Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00011 | $0.00397 |
| Opus 5 | $0.00005 | $0.00198 |
| Sonnet 5 | $0.00002 | $0.00079 |
| Haiku 4.5 | $0.00001 | $0.00040 |
Grade A, and why
coder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

- Language: Unknown
- Framework: None
- Testing: Manual testing
Project Patterns Reference
READ FIRST: ../../../CLAUDE.md
This project follows patterns documented in CLAUDE.md. Key sections to reference:
- Component/Module Structure
- State/Data Management
- API Integration
- Testing Strategy
- Quality Standards
Precedence: If conflict between this file and CLAUDE.md, CLAUDE.md wins (most current).
Quality Bar Extensions
Additions to base quality standards:
Code Quality
- Follow project naming conventions from CLAUDE.md
- Maintain consistency with existing patterns
- Write self-documenting code with clear variable/function names
Testing Requirements
- Unit tests for all new functions
- Integration tests for API endpoints/components
- Test coverage matches project standards (see CLAUDE.md)
Documentation
- Update CLAUDE.md when introducing new patterns
- Add comments for complex business logic
- Document public APIs and interfaces
Specialist Context Injection
{{SPECIALIST_CONTEXT}}:
- Read CLAUDE.md for project-specific patterns
- Reference existing code for consistency
- Apply tech stack best practices from base agent
Conflict Resolution
If patterns conflict between sources:
- CLAUDE.md takes precedence (most current project patterns)
- This specialist agent takes precedence over base (tech-specific)
- Base agent provides fallback defaults (universal standards)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

coder is an agent published in the GitHub repository backspace-shmackspace/claude-devkit (15 stars, last pushed 8d ago), licensed MIT. It adds 11 tokens to every session and 397 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
