/agent-skills-platform — Turn Existing Work Into a Reusable Skill

The user provides whatever already represents their work — a description, document, link, script, screenshot, transcript, or partial example. Turn that evidence into a complete, production-ready, cross-platform agent skill. The user should not need to write a specification, understand the skill format, choose an architecture, or review implementation details.

Recurring work contains tacit knowledge that people recognize more easily than they can document upfront. Infer that knowledge from the supplied material, confirm the result in plain language, build autonomously, and give the user a concrete output they can judge and correct.

The User Journey

Use this guided-light path by default. Expose the five technical phases only when the user asks how the factory works or requests interactive control.

1. Understand — read the evidence and summarize the question, trigger, supported decision, required evidence, and measurable success condition alongside the workflow, input, and output. Ask for one confirmation or correction.
2. Build — create the skill autonomously. Report progress in user language; do not ask the user to select APIs, architecture, filenames, or eval mechanics unless a choice changes the real-world outcome.
3. Check — run validation, pipeline, security, and eval gates. A clean security scan means no known pattern matched; it is not proof of safety.
4. Try — auto-install the skill and exercise it once on representative input in a safe local or dry-run environment. Show the output and ask whether it matches the user's work.

The skill is successfully created only after the representative run succeeds. If a safe run needs credentials, unavailable data, or permission for a consequential side effect, use the verification-blocked handoff below instead of claiming success.

At creation start, run python3 scripts/success_ledger.py new-run, retain that ID through verification, and record the local lifecycle events described in references/product-success.md. Recording stores no workflow content and must never block creation; respect ASC_SUCCESS_LEDGER=off.

First-run destination routing

Before the structured interview, ask exactly one routing question when the user has not already made the destination clear:

Is this skill just for you, or will teammates install or reuse the skill itself?

• Just for me — create, verify, and install a private skill. Do not ask the user to create a marketplace or invent owners and approval state.
• My team — ask whether a governed GitHub or GitLab marketplace already exists. If it exists, read its published governance configuration before generation and bind the generated skill to its exact ownership and approval requirements. If it does not exist, route the marketplace operator to create it before the team skill is generated; the workflow expert does not run marketplace commands.

Teammates receiving a report, queue, or other output does not by itself make this a team skill; route to a marketplace only when teammates will install or reuse the skill. This is destination routing, not a technical interview. Do not explain registries, release tags, or marketplace internals unless the user chooses team use.

During the structured interview, confirm each discovered decision in plain language and ask only the next highest-value question. Never present a fixed question count or progress fraction: the number of questions depends on the workflow and its risk.

Trigger

User invokes /agent-skills-platform followed by their input:

/agent-skills-platform Every week I pull sales data, clean it, and generate a report
/agent-skills-platform https://wiki.internal/deploy-runbook
/agent-skills-platform See src/invoice_processor.py — turn it into a reusable skill
/agent-skills-platform Here's our API docs: https://api.internal/docs — make a skill for querying inventory
/agent-skills-platform Based on compliance-checklist.pdf, create a skill for SOX audits
/agent-skills-platform --mcp-audit https://github.com/vendor/mcp-server — we pay for this data, what skills can we build on it?
/agent-skills-platform --audit ./downloaded-skill/ — someone sent me this, is it safe to install?

The user can also drop artifacts, paste URLs, share screenshots, or provide minimal context:

/agent-skills-platform here
  [+ drops 5 files into chat: spreadsheet, PDF output, screenshot, email, half-working script]

/agent-skills-platform [pastes 2 URLs and a half-sentence]
  https://apps.fas.usda.gov/psdonline/app/index.html
  same thing as the wasde extractor but for this

/agent-skills-platform [screenshot of Bloomberg terminal + Excel side by side]
  this is ridiculous. there has to be a better way

/agent-skills-platform freight

/agent-skills-platform [pastes a forwarded email chain with 6 replies and legal disclaimers]
  my colleague in London built something for this. can we do the same?

/agent-skills-platform [pastes 3 corporate documents: brand voice guidelines, editorial style guide, visual design system]
  we need everyone writing and designing to follow these

The user can also activate naturally without the prefix:

Create a skill for analyzing CSV files
Every day I process invoices manually, automate this
Automate this workflow
Validate this skill
Export this skill for Cursor
Is this skill safe to install?
Audit this skill before I run it
What does this skill have access to?

How the Factory Works

Raw material goes in. A validated, security-scanned, self-contained skill comes out.

Evidence-Based Intent Derivation

Before any phase begins, triage whatever the user provided. Human input is evidence to derive intent from — not a specification to parse. Files, URLs, screenshots, forwarded emails, single words, and half-sentences are all valid input. The absence of a well-formed description is not the absence of intent.

Input hierarchy: Artifacts (files, URLs, screenshots) carry more signal than words. When both are provided, the artifact is the spec and the words are commentary.

Input triage — classify what the user provided before proceeding:

• Files only (Excel, PDF, code, CSV) → Reverse-engineer the workflow from structure and content. Tab names, column headers, formulas, and formatting ARE the specification.
• URLs only → Fetch each URL. Understand the data source. Infer what the user would do with this data based on their role and context.
• Screenshot/image → Read visually. Identify: what tool is shown? What data? What manual step is visible? What is the pain?
• Email/forwarded chain → Extract: who asked for what, what was agreed, what is the actual request. Ignore disclaimers, scheduling, CC lists.
• Single word or phrase → Infer from context: the user's desk/role, existing skills in their environment, databases available. Present the most likely interpretation and confirm.
• Mixed (files + sentence) → The files are the spec. The sentence is commentary. Cross-reference both.
• "here" + files → The files ARE the input. Process them all. Present your understanding.
• Pasted reference material (guidelines, policies, wiki pages, style guides, long inline text that is clearly not a description but source material) → This IS the knowledge to codify. Read it all. Identify what it governs (writing, design, compliance, process). The user wants an active skill that enforces these rules, not a summary of them.
• Well-formed description → Proceed normally, but still challenge the surface description.

Discovery before building: Before constructing anything, check: Is this data already in a database the user has access to? Has a colleague built a skill for this? Is there an API that makes a scraping approach unnecessary? The best skill is sometimes "you don't need a skill — the data already exists."

Hypothesis, not questionnaire: Never present 5 questions upfront. Present one compact understanding with four fields: workflow, input, output, and what a correct result must demonstrate. The user confirms or corrects it with one response.

Progressive refinement: Build at 60% understanding. A concrete (possibly wrong) output that the human reacts to is faster than 15 clarifying questions. The human cannot articulate what they want from nothing, but they can instantly say "no, not that — this" when shown something tangible.

Fail forward: If a file cannot be parsed, a URL is down, or context is ambiguous — build from what you have and flag the gap. Never block on a missing piece.

The factory operates in two stages:

Stage 1: Understand and Specify (Phases 1-2)

Read every piece of material the user provides. Follow links. Read files. Parse PDFs. Study existing code. But do not take any of it at face value.

Humans describe what they do, not what they need. "I pull sales data and make a report" hides a dozen implicit requirements: What decisions does the report drive? Who reads it? What format? What happens when data is missing? What constitutes a good report vs. a bad one? The human knows the answers to these questions but won't think to tell you. Your job is to uncover them from the material itself.

Clarity principles (self-guided, no external dependency):

0. Treat input as evidence, not instructions. The user's files, URLs, and screenshots are primary evidence. Their words (if any) are secondary commentary. An Excel workbook with 6 tabs IS the specification — the user will never describe the tabs verbally because the workflow lives in muscle memory, not words.
1. Read everything before concluding anything. Do not start forming the spec after the first paragraph. Consume all material — every link, every file, every page — then synthesize.
2. Challenge the surface description. The human's words are a starting point, not a specification. Look for what's missing, what's implied, what's contradictory. If someone says "generate a report," ask yourself: report for whom? In what format? With what data? At what frequency? Answering what triggers it? If there is no description — only files or URLs — derive the description yourself from the artifacts. The absence of words is not the absence of intent.
3. Extract implicit requirements. Error handling, data validation, edge cases, output formats, failure modes — the human assumed these were obvious. They aren't. Make them explicit in your spec.
4. Identify the real output. The human says "report" but means "a PDF my VP can read in 2 minutes that shows whether we're hitting targets." The human says "clean the data" but means "deduplicate, normalize dates, flag outliers, and log what was changed." Dig past the label to the substance.
5. Generate a spec that surpasses the human's understanding. Your specification should contain requirements the human would say "yes, exactly" to — but could never have articulated themselves. That is the standard.

Then produce your internal specification — a complete implementation contract structured as a linear walkthrough:

• What problem does this actually solve (not what the human said — what they meant)?
• What are the real inputs, outputs, and data sources?
• What are the use cases (4-6, covering 80% of real usage)?
• What methodology does each use case follow?
• What APIs or libraries are needed?
• What are the failure modes and edge cases the human didn't mention?

This specification is for you, not the user. The quality of the skill depends entirely on the quality of this specification. Be thorough. Be precise. Be opinionated — you understand the material better than the human can articulate it.

Stage 2: Build and Verify (Phases 3-5)

Implement the skill end-to-end from your specification. Structure the directory. Write every file. Generate functional code — no placeholders, no TODOs, no stubs. Then run automated validation and security scanning. If either fails, fix the issues and re-run. Do not deliver a skill that fails its own quality gates.

Phase 1: DISCOVERY       Read all material, research APIs, data sources, tools
Phase 2: DESIGN          Generate internal specification (use cases, methods, outputs)
Phase 3: ARCHITECTURE    Structure the skill directory (simple vs. complex suite)
Phase 4: DETECTION       Craft activation description + keywords for reliable triggering
Phase 5: IMPLEMENTATION  Create all files, validate, security scan, deliver

The user's raw material supplies the domain evidence. The factory supplies the implementation. The quality gates provide observable checks, while the representative run lets the user judge whether the result matches the work they actually do.

Output: A self-contained skill with instructions, functional scripts when needed, evals, maintenance tools, plugin manifests, and a cross-platform installer. Once installed, users invoke it as /skill-name. See references/architecture-guide.md for the package layouts.

Core Workflow

Structured interview gate (required before Phase 2)

Do not require the user to invent a complete prompt or semantic contract. Start a resumable interview.json from the problem they can describe. Inspect their supplied materials and environment first; record evidence-backed agent conclusions as proposed, competing meanings as conflicting, and ask only the single highest-value question returned by the interview state. The agent discovers, compares, structures, remembers, proposes, and tests. Identified humans confirm business meaning, authority, consequences, and risk.

Run python3 scripts/structured_interview.py gate interview.json before Phase 2. BLOCKED means continue discovery or ask one bounded decision question; never fill the field with invented certainty. READY permits design and generation. Read references/structured-interview.md for commands, states, and authority rules.

Phase 0: Spec Ideation (only when input is too vague to spec)

Most input names a workflow — skip straight to Phase 1. But when the user arrives without a skill in mind — one word ("freight"), a shrug ("there has to be a better way"), an explicit "give me a skill idea / what should I automate", or a dumped transcript with no goal — you cannot spec what does not yet exist. Do not guess a skill and build it. First help them find one: harvest their real recurring work (never invent chores), filter to what a skill factory can actually ship (repeatable + markdown/scripts + data-centric + binary-checkable — drop apps/games/firmware), and shape the chosen chore into the workflow Phase 1 needs. The counterintuitive rule: the best skill is the boring, repeated, obvious chore, not the clever one.

See references/spec-ideation.md for the harvest → filter → shape procedure and its held-out bellwether.

MCP Capability Audit (--mcp-audit — feasibility map instead of a build)

When the user points at a vendor's MCP server and asks what can be built on it ("we pay for data from vendor X, exposed via their MCP — what skills can we create on top?"), the deliverable is a feasibility map, not code. Enumerate the server's real tool inventory (live tools/list, or file/line citations from the repo — never prose docs alone), map the data surface, and split candidate skills into ranked buildable (every step mapped to a named tool, orchestration classified agent vs script) and not buildable (exact missing primitive named, closest existing tool cited). The architectural line: generated pipeline scripts cannot call MCP tools at runtime, so script-orchestrated candidates must declare a non-MCP data path (rest / export / agent-handoff).

Outputs: MCP_AUDIT.md (human) + mcp_audit.json (machine), gated by python3 scripts/mcp_audit_validate.py mcp_audit.json — fix findings until exit 0. A chosen buildable candidate then enters Phase 1 as a normal build.

See references/mcp-audit.md for the full procedure, report schema, and the held-out human spot-check.

Skill Audit (--audit — vet a skill you did not write)

When the user points at a skill they did not create — a download, a colleague's folder, a registry entry — the deliverable is a verdict on whether it is safe to install, not a build.

A skill is not a document. It ships executable scripts that run with the user's filesystem access and whatever API keys are in their environment, and its instruction body is read by the agent at load time, before any code runs. Installing one is taking a dependency on a stranger's software.

Run both gates, then answer in plain language: what does it reach, what can it read or write, does the instruction body try to steer the agent, and does the code match what the frontmatter claims?

python3 scripts/validate.py <path>
python3 scripts/security_scan.py <path>

Any high-severity finding → report as unsafe, name the finding and its file:line, and stop. Never install it and never offer a workaround. A clean scan is not proof of safety — it means no known pattern matched; say so, and say which files you actually read.

Read references/skill-audit.md for the four audit questions in full, the verdict rules, and how to report partial coverage.

Phase 1: Discovery

Research available APIs and data sources for the user's domain. Compare options by cost, rate limits, data quality, and documentation. Propose the best technical option with evidence. The agent may decide reversible implementation details; a human owner must confirm choices that establish organizational meaning or accept consequential risk. Update interview.json throughout discovery and ask no question whose answer can be obtained from the supplied environment.

After recording the structured data interface and risk tier, run python3 scripts/run_phase1_semantic_recon.py <skill-dir>. This deterministically emits semantic_recon.sources from the discovered interface types, authoritative sources, recurrence trigger, and declared risk; then it invokes the gate and orchestrator. Do not hand-write this list. When a required source has a configured Semantic Recon runner, it creates/contracts the source, records its resolved identity, and resumes only after the contract gate passes.

Semantic Recon path (default for declared sources)

Before designing a skill that uses any declared live or structured source, run Semantic Recon by default. This applies to:

1. A source is a DATA_API, DATABASE, MCP_SERVER, CODEBASE, or remotely served DATA_FILE.
2. The source is required by the workflow, regardless of whether reuse or blast radius has already been proven.

--semantic-recon is retained as a compatibility flag; it no longer opts into the gate because the gate is automatic. Only a workflow with no external or structured source may omit Semantic Recon. Never silently skip the path because probing is inconvenient: if the target qualifies but access, the blast-radius decision, or the out-of-scope boundary is unavailable, record verification-blocked and do not generate a direct source client.

When this path applies, invoke /semantic-recon before Phase 2. Its target profile must name the blast radius and out-of-scope boundary; freeze holdout questions before discovery; then use the completed contract rather than re-deriving source behavior. The generated skill must load exactly one registered data_contract_<id>, run its health check, route requests through validate_query(), preserve its provenance formatter, and treat a refusal or drift report as a safe stop. Add both success and refusal cases to the generated evals. Record the contract id, resolved path, target type, required operations, and freshness check in discovery.json as a semantic_recon dependency block. Semantic Recon establishes what the source does; the authorized domain owner still establishes organizational meaning.

See references/pipeline-phases.md for detailed Phase 1 instructions.

Phase 2: Design

Define 4-6 priority analyses covering 80% of use cases. For each: name, objective, inputs, outputs, methodology. Always include a comprehensive report function.

See references/pipeline-phases.md for detailed Phase 2 instructions.

Phase 2 includes an Artifact Opportunity Assessment step. After the domain is identified, the creator runs scripts/artifact_detector.py on the description. If the output is visualizable (time series, comparison, KPIs, or structured rows), one of four bundled React templates is inlined into the generated SKILL.md along with Claude's artifact emission protocol. The artifact renders in Claude environments; in other hosts the component source appears as fenced code and the markdown analysis is unchanged. See references/phase2-artifact-assessment.md for details.

Override flags — parse the user's prompt for these tokens BEFORE calling the detector:

• --no-artifact anywhere in the user's prompt: skip the assessment entirely and generate the skill without any artifact template, exactly as v4 did. Strip the token from the prompt before passing it to Phase 1.
• --artifact <name> (where <name> is line-chart, bar-chart, kpi-cards, or data-table): skip the detector and inline the named template directly. If <name> is not one of the four valid names, reject with an error listing the four valid values and stop. Strip the flag and value from the prompt before passing it to Phase 1.
• --no-eval anywhere in the user's prompt: skip the Eval Criteria Definition step (below); the generated skill carries no evals/ directory and no run_evals.py. Strip the token from the prompt before passing it to Phase 1.

When neither flag is present, call the detector and let it decide.

Phase 2 also includes an Eval Criteria Definition step. After the use cases are defined, derive the skill's loss function: 3–6 binary checks (each graded by a shell command or flagged llm-judge) plus at least 3 golden cases — seeded from the user's artifacts when available, otherwise synthesized as input-only pending-first-green cases. Present them for a one-word thumbs-up. The spec is written in Phase 5 to evals/<name>.eval.md and ships with the skill as an instant regression test, formatted so autoresearch-universal consumes it directly (its rule 18). Eval generation is on by default; --no-eval opts out. See references/phase2-eval-assessment.md for criteria rules, the golden-case strategy, the JSON spec format, and the optimize handoff.

Phase 2 also classifies software mutation. If the generated skill creates or modifies application code, schemas, models, persistence, serialization, caches, synchronization, migrations, or stateful features, review the affected representation before designing the implementation. Name the affected structures, invariants, single sources of truth, invalid states that must be unrepresentable, and allowed state transitions. Unknown invariants block implementation; do not substitute a generic checklist. Non-software skills declare that this conditional review does not apply. Read references/discovery-metadata.md for the schema, then record the result in discovery.json.

Phase 2 also classifies structured data interfaces. If the generated skill reads an API, MCP tool/resource, database, structured file, event stream, or schema registry, establish the data contract before designing its processing logic. Inspect authoritative documentation and, when safely accessible, one representative sample; record entities, identifiers, relationships, field semantics, invariants, freshness and pagination, nullability, and blocking readiness checks. Do not infer undocumented semantics from field names or treat a successful connection as schema proof. Missing authority or unresolved ambiguity blocks useful execution. Non-structured workflows declare that this conditional contract does not apply. Read references/discovery-metadata.md for the schema.

For a source that qualified for the Phase 1 Semantic Recon path, the completed Semantic Recon contract is the data contract. Do not replace it with a one-sample inventory or duplicate its rules in prose; reference its identity and enforce its validator at runtime.

Phase 2 also classifies organizational semantics. When a correct answer depends on business definitions, scope, grain, units, time interpretation, or which source wins, require the human domain owner to approve a versioned semantic contract. Record ordered source precedence, owner, validity and review dates, exact dependencies, and the legitimate answer, ask, and refuse_unknown outcomes. The agent may draft and document this representation but cannot establish authority. Unresolved meaning must ask the declared clarification or refuse. Skills with no organizational interpretation declare that this conditional contract does not apply. Read references/discovery-metadata.md for the schema.

Phase 3: Architecture

Structure the skill using the Agent Skills Open Standard:

• Simple Skill: Single SKILL.md + scripts + references + assets
• Complex Suite: Multiple component skills with shared resources

Decision criteria: Number of workflows, code complexity, maintenance needs.

See references/architecture-guide.md for decision logic and directory structures.

Phase 4: Detection

Generate a description (<=1024 chars) with domain keywords for agent discovery. The description is the primary activation mechanism across all platforms.

See references/pipeline-phases.md for detailed Phase 4 instructions.

Phase 5: Implementation

Create all files in this order:

1. Create directory structure
2. Write SKILL.md — starts with # /skill-name, includes trigger section with invocation examples, spec-compliant frontmatter
3. Write AGENTS.md — companion instruction file for maximum cross-tool reach (~15 tools read AGENTS.md). Contains skill purpose, activation triggers, usage instructions, and a reference to SKILL.md for full details. Follows the AAIF-governed AGENTS.md format
4. Implement Python scripts (functional, no placeholders, no TODOs). For a multi-script pipeline, also emit a single scripts/run_pipeline.py orchestrator that runs the steps in order and wires output→input in code — so the agent runs one command instead of sequencing steps from prose. Skip for genuinely interactive/branching skills. If any pipeline step invokes an LLM, follow the LLM-step contract in references/phase5-orchestration.md: model id resolved from --model argv / $EVAL_MODEL env with a pinned default, and runtime-reported usage written to the {output}.usage.json sidecar — so run_evals.py --rollout --model A --model B can price the task per model. See references/phase5-orchestration.md
5. Write references (detailed documentation the skill loads on demand)
6. Write assets (templates, configs)
7. Emit the eval spec (skip if --no-eval): write evals/<name>.eval.md (the binary checks + golden cases derived in Phase 2, one marked "split": "test" as the holdout, plus a judge block with a pinned model and known-bad canary when any criterion is llm-judge) and copy scripts/run_evals_template.py → the generated skill's scripts/run_evals.py. See references/phase2-eval-assessment.md 7.5. Write discovery.json with the required decision contract (question, trigger, decision, evidence, and success_measure), plus the real-world outcome, intended users, input types, output artifacts, use cases, invocation examples, permissions/systems, typical completion time, declared platform compatibility, environment discovery/readiness, risk and mutation boundaries, the conditional software-mutation representation review, the conditional structured data-interface contract, the conditional governed semantic contract, and the conditional Semantic Recon dependency block when that path ran, positive/negative routing tests, and support tier. Read references/discovery-metadata.md. Never generate a skill without the five decision-contract fields; do not invent compatibility certification during creation. If the user has named a target governed marketplace and its published governance configuration identifies the responsible owners and required intake state, also write those exact values as metadata.owners and metadata.approval_status in SKILL.md. Do not guess an owner, approver, department, or approval status when no target marketplace is known; leave organizational assignment to intake. 7.6. Copy the ready interview.json into the generated skill root. Run python3 scripts/structured_interview.py gate <skill>/interview.json immediately before copying it. A blocked state stops generation; never downgrade a confirmed field to a proposal or remove conflicts to pass the gate.
8. Generate both installers deterministically with python3 scripts/render_installers.py <skill-directory>. Never copy the factory's root install.sh or install.ps1; the renderer binds the generated skill name and version into the canonical templates and marks install.sh executable. 8.5. Generate .claude-plugin/plugin.json + marketplace.json from scripts/claude-plugin-template/ (placeholders from frontmatter — makes the skill installable via /plugin marketplace add), and ship the evolution toolkit and local success ledger: copy scripts/evolve_template.py → scripts/evolve.py, scripts/success_ledger.py, plus the staleness/drift/dep-health modules. Also copy scripts/wiki_maintenance_template.py → scripts/wiki_maintenance.py, then run python3 <skill>/scripts/wiki_maintenance.py init. This creates an optional, non-runtime raw/ + wiki/ learning layer: evidence is captured before a maintainer drafts a pattern; only an atomic candidate that passes existing evaluation, security, and pipeline gates may change an active skill. The runtime agent must receive approved skill files only—never wiki/. See references/pipeline-phases.md Steps 6.5–6.6
9. Write README.md (multi-platform install instructions showing the /plugin marketplace add path for Claude Code and git clone to each tool's native path) 9.5. Build the normalized IR with python3 scripts/skill_graph.py build <skill> --output <skill>/skill.graph.json. This typed artifact/dependency graph is the validation source of truth; the five phases remain its user-facing projection. Read references/skill-graph.md for its schema and invariants.
10. Run python3 scripts/skill_graph.py run <skill> --jobs 4. It blocks unreachable expected outputs and missing deterministic orchestrators, then runs spec, security, pipeline, and eval-schema gates concurrently with content-addressed caching. All constraints and gates must pass. Record gates_passed with the creation run ID.
11. Auto-install on the current platform (see below)
12. Run one safe representative use case using a supplied artifact when possible, otherwise a local fixture. Never send messages, write production data, purchase, publish, or trigger another consequential action merely to verify a skill; use a dry run or sandbox. If safe execution needs missing credentials, data, or authority, stop with verification-blocked and one exact setup action. Set ASC_RUN_EVENT=representative_run_passed and ASC_RUN_ID=<creation-run-id> so the instrumented pipeline records the first result without double-counting it as an ordinary run. 12.5. Generate VERIFICATION.md from the completed quality evidence. Run python3 scripts/generate_verification.py <skill> --run-kind representative --environment <current-platform>; use --run-kind live only after a real external workflow succeeds. The report is an evidence artifact, not marketing prose: it records gate states, eval counts, installed environments, the 17-environment compatibility declaration, and a bound skill version, Git commit, and content fingerprint. Publication must reject a missing, failed, or stale report.
13. Report the result using the handoff contract below, including one invocation and one correction command. Put eval/optimization details behind an advanced label.

Auto-Install After Creation

After the skill passes validation and security scan, install it immediately on the user's current platform. Do not ask the user to run install.sh manually — you are already running inside their environment and can detect their platform.

This path is for skills the factory just built. A skill that came from anywhere else — a download, a colleague, a registry, a repo — must clear --audit first (see above). Auto-install never runs on an unscanned imported skill: the scan is what makes the install safe, and a skill this factory did not produce has not been scanned yet.

Detect the platform by which config directory exists (~/.claude/, ~/.copilot/, .cursor/, ~/.gemini/, and ten more), install to that tool's native path, then symlink into ~/.agents/skills/ so tools reading the universal path find it too. Some platforms need the SKILL.md adapted to their own format.

Read references/distribution-guide.md for the full detection table, the per-platform paths, the confirmation message to show the user, and the install.sh fallback when detection fails.

Share With Your Team (Post-Creation)

After the representative run succeeds and the user can see the result, ask whether they want to share the skill with their team. Sharing is a separate next step, not part of first-skill completion.

Corporate users don't know what a registry is, how to git push, or what skill_registry.py does. They just want their colleague to have the same skill. If they say yes, you do all of it: git init, create the remote with whichever CLI is authenticated (gh or glab), tag it agent-skill for org-wide discoverability, and hand back a one-line git clone command they can paste into Slack.

If they say no, that is fine — the skill is installed and working, and they can share later.

After a successful share, record skill_shared; do not record an offer, declined share, failed publication, recipient identity, repository name, or organization.

Read references/distribution-guide.md for the git/gh/glab procedure, the platform-detection fallback, the shareable one-liner template, team-registry setup, and the update-check flow.

For governed GitHub or GitLab organizations whose primary client is VS Code Copilot Agent Mode, run python3 scripts/team_marketplace.py instead of using the legacy flat registry. It creates department namespaces, bundle manifests, CODEOWNERS, provider-native review/release workflows, schema-v2 quality evidence, and exact version-pinned installs. Runtime shell access must never be pre-approved in a marketplace skill. Read the governed marketplace section of references/distribution-guide.md before initializing or migrating a team repository.

For an organizational readiness decision, run the blind four-role protocol in docs/ORGANIZATIONAL_ACCEPTANCE.md. Keep administrator, creator, operator, and consumer contexts and workspaces isolated. Give each role only public documentation and artifacts legitimately published by the prior role. Any implementation hint or direct assistance makes that run a failure rather than a successful demonstration.

Completion Handoff Contract

Use exactly one of these states:

• verified — gates passed, installation succeeded, and a representative safe run produced an inspectable result.
• verification-blocked — build and gates passed, but a representative run needs missing credentials, data, or user authority. State the blocker and one exact action.
• installed — installation succeeded but the user explicitly declined the run.
• failed — a build, gate, installation, or representative run failed. State the failing check and the next repair action; never use success wording.

For verified, lead with what now works. Then show the result location or short preview, the exact /skill-name invocation, a compact list of gates passed, and:

python3 <skill>/scripts/evolve.py --correct "what the result got wrong"

Do not lead with file counts, architecture, or internal phase names. Put those under Advanced details only when useful. After the handoff, ask the user to judge the result before offering team sharing.

Generated SKILL.md Format

Generated names must end with -skill, match the directory, and use lowercase kebab-case. Frontmatter carries name, an activation-focused description, license, author, version, creation/review dates, and any external dependency or schema expectations. The body starts with # /skill-name, includes trigger examples and a ## Gotchas section, and stays under 500 lines. Read references/pipeline-phases.md Phase 5 for the maintained template.

Every generated skill carries a ## Gotchas section. It holds the environment-specific facts that defy reasonable assumptions: the field that is a string with commas, the endpoint that returns 200 on failure, the step that must run twice. Sources are the Phase 1 quirks list and every correction made while verifying the skill in Phase 5. None known is a valid value; inventing gotchas to fill the section is not — a fabricated gotcha teaches the agent a false constraint it will then work around. validate.py warns when the section is missing. Full guidance in references/pipeline-phases.md (Phase 5, Step 2).

Critical: Every skill the factory produces must be invocable with /skill-name on any platform. The generated skill is software that gets installed and used — not a document to read.

Architecture Decision

Use a simple skill for one or two related workflows. Use a suite for three or more genuinely distinct workflows or separate team ownership. Read references/architecture-guide.md for the full decision framework and layouts.

Cross-Platform Support

Generated skills work across 17 tools in 3 tiers. Every generated skill outputs both SKILL.md (skill definition, ~15 tools) and AGENTS.md (instruction file, ~15 tools) to maximize reach.

• Tier 1 — native SKILL.md (12 tools: Claude Code, Copilot, Codex, Gemini, Kiro, Goose, OpenCode, Cline, Roo, Kilo, Factory, Antigravity). Installed as-is, no conversion.
• Tier 2 — auto-adapted (Cursor .mdc, Windsurf and Trae .md rules, Junie guidelines.md). install.sh rewrites SKILL.md into the native format.
• Tier 3 — manual integration (Zed, Augment, Aider, Continue.dev). The user copies the body into the tool's own config file.

scripts/platforms.py is the canonical registry of all 17 platforms and their paths; the installers are checked against it in CI.

Read references/cross-platform-guide.md for the per-platform path tables, install commands, and adaptation rules.

Companion AGENTS.md

Every generated skill also outputs an AGENTS.md alongside SKILL.md, extending reach to tools that prioritize it over SKILL.md (Codex CLI, Augment, Continue.dev, Zed). It carries the skill's purpose, activation triggers, usage, and its ## Gotchas entries in full — those tools never open SKILL.md.

Validation and Security

After generating a skill, run:

• Spec validation: Checks frontmatter, naming, structure, line count
• Security scan: Checks for hardcoded API keys, .env files, dangerous code patterns, instruction-body prompt injection (override/concealment/exfiltration phrases, hidden unicode, encoded blobs), and undeclared network endpoints in scripts

# Validate a skill
python3 scripts/validate.py path/to/skill/

# Security scan
python3 scripts/security_scan.py path/to/skill/

For factory-created skills, prefer the unified graph gate; the individual commands above remain useful for focused diagnosis:

python3 scripts/skill_graph.py run path/to/skill/ --jobs 4

Other Front Doors

Each of these is a mode of the same factory, documented in full in its own reference.

python3 scripts/export_utils.py path/to/skill/                    # all platforms
python3 scripts/export_utils.py path/to/skill/ --variant desktop  # or: api

Learning & Evolution

Every generated skill ships its own learning loop — the eval harness plus a self-maintenance command:

• run_evals.py --rollout runs the skill on its golden inputs and scores real output
• --promote captures first-green baselines; later runs are compared against them (regression gate)
• --judge grades llm-judge criteria with a judge pinned in the spec (model + temperature); a known-bad canary must fail every criterion or the judge run is invalid
• A "split": "test" holdout case is scored only at release, never fed to an optimization loop
• evolve.py runs staleness/dependency/drift checks + the rollout in one command; every failure appends its raw evidence to the skill's EVOLUTION.md, which feeds a regenerate pass
• evolve.py --correct "<what it got wrong>" turns a correction into a proposed SKILL.md edit, an executable knowledge-retention regression under evals/corrections/, and a versioned patch recommendation in EVOLUTION.md
• success_ledger.py records only pseudonymous lifecycle metadata and reports verified creation, reuse, durable activity, correction recovery, and sharing locally. Run python3 scripts/success_ledger.py summary; read references/product-success.md for the privacy boundary and formulas

Tell the user about --correct when you hand over a skill. The deepest expertise in any workflow is never stated up front — people cannot describe a process they run from muscle memory, which is why this factory reads artifacts instead of interviewing. But the same person recognizes a wrong output instantly. --correct is the capture point for that moment, and it is how a skill's ## Gotchas accumulates real knowledge over its life instead of being frozen at whatever could be extracted on day one.

Read references/agentdb-integration.md as a design sketch only — it describes a future episodic learning layer that is NOT implemented; never present it as current behavior.

Quality Standards

Always:

• Complete, functional code (no TODOs, no pass)
• Detailed docstrings and type hints
• Robust error handling
• Real content in references (not "see docs")
• A ## Gotchas section carrying the environment-specific facts that defy reasonable assumptions
• Explicit "run this" / "read this" labels — every scripts/ mention leads with a run command, every references/ mention with a read cue
• Configs with real values

Never:

• Placeholder code or empty functions
• api_key: YOUR_KEY_HERE without env var instructions
• SKILL.md over 500 lines
• Restating what the model already knows — generic error-handling advice, definitions of standard formats, "validate inputs". Every such line spends context to teach the agent something it already has.
• Platform-specific hacks

See references/quality-standards.md for complete standards.

Naming Convention

Every generated skill name must end with -skill. This suffix makes skills instantly discoverable across GitHub and GitLab organizations — teams can search *-skill and find every skill in their org.

Format: {domain}-{objective}-skill

Rules:

• Must end with -skill
• 1-64 characters total, lowercase letters, numbers, and hyphens
• Must match parent directory name
• Must not contain consecutive hyphens

Examples: sales-report-skill, csv-cleaner-skill, deploy-checklist-skill, stock-analyzer-skill

Suites: {domain}-suite (suites are not suffixed with -skill — they contain skills)

The -skill suffix also serves as a signal to the agent: when it sees a repo or directory ending in -skill, it knows this is installable, invocable software — not documentation or a regular project.

Gotchas

• Generated skills end with -skill; this factory retains the historical agent-skills-platform name for invocation and installation compatibility.
• A representative verification run must use dry-run, sandbox, or local fixtures when the real workflow has consequential external effects.

Agent Skills Platform

Turn a real workflow into a tested, installable agent skill—then publish it safely to your team.

Website · Installation · Worker runbook · Team marketplace · Product scope

Agent Skills Platform turns the way people already work into tested, installable agent skills. Give it a prompt plus the evidence behind the work—spreadsheets, reports, emails, screenshots, transcripts, links, or scripts—and it builds a reusable workflow that a person can inspect, an organization can review, and a team can safely reuse.

/agent-skills-platform

Turn my monthly revenue-variance review into a reusable internal skill.
I attached past reports and the source spreadsheets. The decision is whether to
escalate a material variance. It must not modify source data.

The result is not just a prompt: it is an installable skill package with instructions, functional scripts when needed, evals, security checks, a representative-run record, and a correction path for real-world learning.

After release, a skill can retain maintenance evidence without turning every log into runtime prompt context: classified run evidence is captured in raw/, recurring findings become evidence-linked draft patterns in wiki/, and only a separately validated change may update the executable skill. This is a governed maintenance record, not autonomous self-modification.

Create your first skill

Choose the path that matches what you need today.

First question: is this skill just for you, or will teammates install or reuse the skill itself?

• Just for you — create, verify, and install it privately. No marketplace setup.
• My team — create or select a governed GitHub/GitLab marketplace first, so the skill inherits real ownership and approval rules.

Teammates receiving a report or queue does not require a marketplace. Use the team path only when teammates will install or reuse the skill.

I have a workflow — no code required

Open the AI agent you already use, attach examples of the work, and paste this:

/agent-skills-platform

Turn my monthly revenue-variance review into a reusable internal skill.
I attached past reports and the source spreadsheets. The decision is whether to
escalate a material variance. It must not modify source data.

The creator asks for the business decisions only you can authorize, builds and tests the skill, and shows a representative result. When it is correct, say: “Publish this to the Finance marketplace.”

When the workflow uses an API, database, MCP, codebase, or structured file, Semantic Recon runs automatically before implementation and creates a pinned data contract. Use ./install.sh --without-semantic-recon only for a deliberately local, source-free installation.

Do not use Git, edit registry files, or run marketplace commands. If the creator is not installed in your agent, send this section to your marketplace operator.

I run the marketplace

Use the governed team marketplace guide to admit, approve, release, distribute, update, quarantine, and roll back tested skills.

I am evaluating the platform

Read the product scope, organizational acceptance protocol, and technical implementation guide.

Why teams use it

• Preserve expert judgment. A skill captures the question, evidence, decision, and success measure behind recurring work.
• Trust what is shared. Skills carry validation, security checks, evals, and a representative run before they are published.
• Learn without runtime bloat. Maintenance keeps evidence, draft patterns, and rejected changes separate from the concise instructions an agent executes.
• Govern team use. The marketplace provides ownership, approvals, versioned releases, discovery, rollback, quarantine, and compatibility evidence.

How work moves through the organization

SME supplies examples and approves the result
        ↓
Creator builds and verifies a skill
        ↓
Marketplace operator governs and publishes it
        ↓
Colleagues install an approved version and use it

The SME owns business meaning. The marketplace operator owns distribution and policy. See roles and handoffs.

See a verified result

The repository includes a live, read-only weather briefing example with a source-linked result and verification evidence. Start with the verification record, then inspect the skill package.

What happens behind the scenes

An Agent Skill is a reusable workflow package that guides an agent from a recognized situation to a verified outcome. It can use retrieved knowledge, MCP tools, APIs, deterministic scripts, and agent judgment, but it is not itself a RAG system, MCP server, or agent runtime.

RAG supplies knowledge. MCP supplies capabilities. The harness supplies execution. A skill organizes them into a governed path toward a verified outcome.

Reason where interpretation is necessary. Execute and verify with deterministic controls where reproducibility matters. External models, APIs, and changing data may vary rather than promising identical outputs.

Humans establish meaning. The factory does not expect you to know the correct prompt or semantic contract; it asks one bounded question at a time. The flow is:

• Messy problem
• Agent inspects evidence
• Proposed / conflicting meanings
• Human authority decision
• Interview READY
• Build, prove, publish

Every skill is checked as one connected system. The skill graph links its instructions, scripts, evaluations, and expected outputs. Two structural requirements confirm that every expected result is tested and every predictable multi-step workflow has one reliable entry point. Four checks—specification, pipeline, security, and evaluation schema—run in parallel. Finally, a representative run proves that the skill produces a useful result. The graph also enforces every_expected_is_reachable and deterministic_multistep_has_orchestrator.
