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 | $0.00059 | $0.00725 |
| Opus 5 | $0.00030 | $0.00362 |
| Sonnet 5 | $0.00012 | $0.00145 |
| Haiku 4.5 | $0.00006 | $0.00072 |
Grade B, and why
agents-md scanned grade B with 1 finding 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.

Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.
find .claude/skills -name "SKILL.md" 2>/dev/null How it starts
The opening of the file, as written. The whole thing — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Maintaining AGENTS.md
AGENTS.md is the canonical agent-facing documentation. Keep it minimal—agents are capable and don't need hand-holding.
File Setup
- Create
AGENTS.mdat project root - Create symlink:
ln -s AGENTS.md CLAUDE.md
Before Writing
Discover local skills to reference:
find .claude/skills -name "SKILL.md" 2>/dev/null
ls plugins/*/skills/*/SKILL.md 2>/dev/null
Read each skill's frontmatter to understand when to reference it.
Writing Rules
- Headers + bullets - No paragraphs
- Code blocks - For commands and templates
- Reference, don't duplicate - Point to skills: "Use
db-migrateskill. See.claude/skills/db-migrate/SKILL.md" - No filler - No intros, conclusions, or pleasantries
- Trust capabilities - Omit obvious context
Required Sections
Package Manager
Which tool and key commands only:
## Package Manager
Use **pnpm**: `pnpm install`, `pnpm dev`, `pnpm test`
Commit Attribution
Always include this section. Agents should use their own identity:
## Commit Attribution
AI commits MUST include:
Co-Authored-By: (the agent model's name and attribution byline)
Example: `Co-Authored-By: Claude Sonnet 4 <[email protected]>`
Key Conventions
Project-specific patterns agents must follow. Keep brief.
Local Skills
Reference each discovered skill:
## Database
Use `db-migrate` skill for schema changes. See `.claude/skills/db-migrate/SKILL.md`
## Testing
Use `write-tests` skill. See `.claude/skills/write-tests/SKILL.md`
Optional Sections
Add only if truly needed:
- API route patterns (show template, not explanation)
- CLI commands (table format)
- File naming conventions
Anti-Patterns
Omit these:
- "Welcome to..." or "This document explains..."
- "You should..." or "Remember to..."
- Content duplicated from skills (reference instead)
- Obvious instructions ("run tests", "write clean code")
- Explanations of why (just say what)
- Long prose paragraphs
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.

agents-md is a skill published in the GitHub repository klh/speedy-claude (11 stars, last pushed 3d ago), licensed MIT. It adds 59 tokens to every session and 725 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
