職人 · Shokunin

62 engineering skills + persistent AI memory. One command. Zero servers.

v4.2.3 adds freshness decay (time-weighted memory), claim verification (verify_file_path MCP tool), 9 MCP tools (was 8), and 30+ bug fixes.

職人 (shokunin) means artisan in Japanese. These skills aim for that standard: every detail crafted, every edge case handled, every workflow automated.

Ecosystem

OpenCode + VS Code + WezTerm
  62 skills + superpowers plugin + 4 subagents
  MCP servers: filesystem, fetch, memory + ChromaDB
  AI: OpenCode Go (default) + Ollama (local fallback)
  Update system: declarative manifest with drift detection
  Windows (PowerShell) + Linux (bash)

Skills

62 skills across 10 domains. Each skill teaches the agent how to handle a specific domain: with decision tables, error patterns, production checklists, anti-patterns, and cited sources. Not generic prompts. Real engineering guides.

The Docker skill is 1,422 words with a multi-stage Node.js template, BuildKit cache optimization, distroless base images, and CVE scanning. The auth skill references OWASP directly. The database one has real EXPLAIN ANALYZE output. Frontend skills include Emil Kowalski patterns (Sonner, Vaul), Paul Bakaus principles (Impeccable), and Leon Lin variance engines (Taste). Skills are validated by CI on every push: frontmatter, workflow, error handling, sources. All mandatory.

Each skill includes: trigger-optimized descriptions, procedural workflows, error handling, production checklists, anti-patterns, cited sources. Advanced skills also include executable scripts, reference files, and reusable templates.

What You Get

Requirements

Minimum

Linux: additional dependencies

Ubuntu 24.04+: PEP 668 blocks global pip install by default. The installer handles this automatically with --break-system-packages. If you run into issues, see the Troubleshooting section below.

Windows: additional notes

• PowerShell 5.1+ required. Run $PSVersionTable.PSVersion to verify.
• Execution policy must allow scripts: Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

Quick Start

Windows:

# 1. Install
irm https://raw.githubusercontent.com/EliasOulkadi/shokunin/master/install.ps1 | iex

# 2. (Optional) Free NVIDIA API key, or skip, OpenCode Go works without it
#    https://build.nvidia.com/

# 3. Start OpenCode (with memory capture)
.\run-opencode.ps1

# Or without memory capture (simple mode):
opencode

Linux:

# 1. Install
bash <(curl -sL https://raw.githubusercontent.com/EliasOulkadi/shokunin/master/install.sh)

# 2. (Optional) Free NVIDIA API key, or skip, OpenCode Go works without it
#    https://build.nvidia.com/

# Quick Start (non-interactive):
bash <(curl -sL https://raw.githubusercontent.com/EliasOulkadi/shokunin/master/install.sh) -y

# 3. Reload shell and start OpenCode
source ~/.bashrc
opencode

Memory System v4.2.3

Multi-strategy recall (vector + BM25 + temporal + reciprocal rank fusion). Session management with explicit continue (no guessing which session to resume).

• Freshness decay: exponential recency blending — old memories fade over 30-day half-life so stale claims don't drown out recent context
• Claim verification: verify_file_path MCP tool validates file paths from old memory before the agent acts on them — treats memory as claims from a frozen point in time, not facts
• 9 MCP tools (up from 8): store_context, search_context, get_session_summary, multi_search_context (vector+BM25+RRF+temporal), consolidate_memories, list_sessions, continue_session, save_message, verify_file_path

# List recent sessions
python ~/.shokunin/scripts/chroma-helper.py session list 5

# Continue a specific session (loads full context)
python ~/.shokunin/scripts/chroma-helper.py session continue <session_id>

# Search across all memory
python ~/.shokunin/scripts/chroma-helper.py recall "topic"

All data stored at ~/.shokunin/memory/. No cloud, no telemetry, no subscriptions.

# Test the memory system
.\test-memory.ps1

# Validate all memory components
.\memory-healthcheck.ps1
