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 5.1 | $0.00553 | $0.00553 |
| Opus 5 | $0.00277 | $0.00277 |
| Sonnet 5 | $0.00111 | $0.00111 |
| Haiku 4.5 | $0.00055 | $0.00055 |
Grade A, and why
hgm CLAUDE.md 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 5d 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.
This is a copy
75% identical to spectrum-design-data AGENTS.md — 78 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Instructions for AI Agents
This file provides instructions and context for AI coding agents working on this project.
Beads Issue Tracker
This project uses bd (beads) for issue tracking. Run bd prime to see full workflow context and commands.
Quick Reference
bd ready # Find available work
bd show <id> # View issue details
bd update <id> --claim # Claim work
bd close <id> # Complete work
Rules
- Use
bdfor ALL task tracking — do NOT use TodoWrite, TaskCreate, or markdown TODO lists - Run
bd primefor detailed command reference and session close protocol - Use
bd rememberfor persistent knowledge — do NOT use MEMORY.md files
Architecture in one line: issues live in a local Dolt DB; sync uses refs/dolt/data on your git remote; .beads/issues.jsonl is a passive export. See https://github.com/gastownhall/beads/blob/main/docs/SYNC_CONCEPTS.md for details and anti-patterns.
Session Completion
When ending a work session, you MUST complete ALL steps below. Work is NOT complete until git push succeeds.
MANDATORY WORKFLOW:
- File issues for remaining work - Create issues for anything that needs follow-up
- Run quality gates (if code changed) - Tests, linters, builds
- Update issue status - Close finished work, update in-progress items
- PUSH TO REMOTE - This is MANDATORY:
git pull --rebase git push git status # MUST show "up to date with origin" - Clean up - Clear stashes, prune remote branches
- Verify - All changes committed AND pushed
- Hand off - Provide context for next session
CRITICAL RULES:
- Work is NOT complete until
git pushsucceeds - NEVER stop before pushing - that leaves work stranded locally
- NEVER say "ready to push when you are" - YOU must push
- If push fails, resolve and retry until it succeeds
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.

hgm CLAUDE.md is an instructions file published in the GitHub repository weill-labs/hgm (2 stars, last pushed 3mo ago), licensed MIT. It adds 553 tokens to every session, about $0.0028 per session on Opus 5. A static security scan graded it A with 0 findings. It is 75% identical to spectrum-design-data AGENTS.md, differing in 78 lines, and is treated as a copy.
