Give your AI agent a clear finish line.
You ask for a fix and get a new abstraction. A review lists generic advice. The agent says “done,” but you still have to work out what it checked.
These skills give Claude Code and Codex a concrete way to finish the task: establish the intended outcome, work within scope, verify the result, and make remaining gaps explicit. Choose the skill for the problem in front of you.

Start where you need help. Each skill works independently; a small fix does not require a full lifecycle or audit.
| Your problem | Plugin to install | Useful result |
|---|---|---|
| Is this idea worth building? | product-discovery-suite |
A reasoned opportunity decision, clear requirements, or a usable interaction design. |
| How should this system change? | architecture-suite |
An evidence-backed system map, design decision, or migration approach. |
| Is this plan ready to implement? | delivery-planning-suite |
Missing decisions exposed, work sequenced, and verification planned. |
| Fix, upgrade, simplify, or speed up this code. | implementation-suite |
A bounded change checked against the intended behavior and benefit. |
| What could go wrong with this delivery or codebase? | quality-assurance-suite |
Prioritized findings tied to evidence, or acceptance tests for the agreed scope. |
| Get this change published or deployed. | delivery-suite |
The authorized destination updated and the observed result checked. |
| Why did this fail, or did the feature help? | operations-suite |
An evidence-backed diagnosis or product outcome assessment. |
| Can I trust the instructions in this skill? | skill-maintenance-suite |
A review of its boundaries, consistency, and distribution readiness. |
For a larger task, combine only the steps needed to resolve decisions and produce evidence. Supplied requirements, existing designs, and current tests are valid starting points. Implementation includes its own verification; a separate test-building or review skill is optional.
For a feature or fix, start with implementation-suite. Replace it with another plugin from Choose a route for a different task.

| Index | Skill | Purpose |
|---|---|---|
| 11 | Opportunity Evaluator | Evaluates new product opportunities through demand, channels and economics before committing to build. |
| 12 | Product Requirements Builder | Defines product requirements, business rules and acceptance criteria for a committed intent; edits product docs only. |
| 13 | Interaction Design Builder | Designs user flows, interaction states and mockups for a defined product scope; does not implement UI code. |
Understand the system you have and choose changes with clear boundaries, tradeoffs, and recovery paths.
| Index | Skill | Purpose |
|---|---|---|
| 21 | System Design Baseline Builder | Defines measurable architecture drivers and constraints before system design; edits architecture docs only. |
| 22 | Current Architecture Documenter | Documents current architecture from implementation evidence; does not propose a target or audit fitness. |
| 23 | System Design Proposal Builder | Designs target system boundaries, contracts and tradeoffs from requirements; does not plan tasks or implement. |
| 24 | Architecture Decision Recorder | Records one architecture decision with alternatives, consequences and status; does not design the whole system. |
| 25 | Architecture Diagram Builder | Creates evidence-backed current or target architecture diagrams; not UI design. |
| 26 | Architecture Migration Planner | Plans architecture migrations with compatibility, data safety, rollout and recovery; does not execute them. |
Find missing decisions and risky dependencies before they become implementation rework.
| Index | Skill | Purpose |
|---|---|---|
| 31 | Delivery Plan Builder | Builds dependency-ordered delivery plans from requirements and repository evidence; read-only. |
| 32 | Test Strategy Planner | Plans risk-based test portfolios and acceptance evidence; does not write or execute tests. |
| 33 | Plan Reviewer | Reviews a concrete implementation plan for missing decisions, feasibility and risk before execution; read-only. |
Fix the cause, reuse what already works, and keep changes focused on a verified outcome.
| Index | Skill | Purpose |
|---|---|---|
| 41 | Surgical Change Implementer | Implements one scoped feature or fix through the smallest complete solution; not upgrades or performance tuning. |
| 42 | Dependency Upgrader | Upgrades dependencies in reversible batches with version-specific compatibility and regression checks. |
| 43 | Code Modernizer | Modernizes a bounded capability to reduce demonstrated maintenance cost; not routine upgrades or performance tuning. |
| 44 | Performance Optimizer | Profiles and improves a measured performance bottleneck; retains only verified improvements. |
| 45 | Benchmark Comparator | Compares tools or implementations through controlled benchmarks and independent correctness checks. |
Find gaps that could break a release, mislead a maintainer, or make a passing test meaningless.
| Index | Skill | Purpose |
|---|---|---|
| 51 | Acceptance Test Builder | Builds, updates or retires scoped acceptance tests and verifies execution; does not repair product code. |
| 52 | Delivery Reviewer | Reviews a completed change for acceptance, regressions and release risk; read-only, not a whole-codebase audit. |
| 53 | Documentation Auditor | Audits documentation and comments for trust, coverage, consistency and freshness; read-only. |
| 54 | Codebase Auditor | Audits cross-cutting codebase health, security and maintainability; not a single-change review or specialist audit. |
