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 | $0.00082 | $0.01308 |
| Opus 5.5 | $0.00033 | $0.00523 |
| Sonnet 5.5 | $0.00016 | $0.00262 |
| Haiku 4.5 | $0.00008 | $0.00131 |
Grade A, and why
agent-init 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 2mo 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.

AGENTS.md Guide
Overview
Provide a repeatable workflow and quality bar for writing or updating AGENTS.md files so agents receive concrete, repo-specific instructions.
Trigger examples
- "Create an AGENTS.md for this repo and include exact test commands."
- "Replace our agent init command with a proper AGENTS.md file."
- "Audit our existing AGENTS.md for missing boundaries and commands."
- "Update AGENTS.md to reflect the current build and lint commands."
- "Create CLAUDE.md as a symlink to AGENTS.md for Claude Code."
Core Principles (condensed)
- Be concrete: prefer executable commands and code examples over prose.
- Put commands early and include flags/options.
- Use real code examples over explanations.
- Remove ambiguity: state boundaries and non-goals explicitly.
- Be specific about the tech stack; include versions and key dependencies.
- Define the agent's role/persona and how it fits the team.
- Cover the six core areas: purpose, code organization, run/test/validate, change management, dependencies/environment, and avoid list.
- Use three-tier boundaries: Always / Ask first / Never.
- Start small and iterate as the repo evolves.
Brainstorming Mode (divergent Q&A)
Use this mode when requirements are unclear or the repo structure will influence the document shape.
- Ask one question at a time. Prefer multiple choice when possible.
- Base questions on the actual repo shape (single app vs monorepo).
- Confirm which agents will consume the docs and their expectations.
- If Claude Code is in scope, plan a CLAUDE.md symlink to AGENTS.md.
- Ask for exact commands (with flags) and a real code example.
- Propose 1-2 AGENTS.md layouts (section order) with tradeoffs, then converge.
- Keep questions short and actionable, then confirm before drafting.
- Read
references/agents-md-brainstorm.mdfor question banks and decision heuristics.
Workflow
1) Clarify scope and placement
- Confirm whether the task is to create new docs or revise existing ones.
- Default output is root
AGENTS.md. - If the user asks for a different location, confirm the exact path and proceed.
- If Claude Code is in scope, create
CLAUDE.mdas a symlink toAGENTS.md. - Still maintain a single AGENTS.md (no per-agent files unless explicitly requested).
- Confirm which agents will consume the docs and align content with their workflows.
- If the repo uses a different location or filename, ask before proceeding.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

agent-init is a skill published in the GitHub repository dyxushuai/agent-skills (2 stars, last pushed 9mo ago), licensed MIT. It adds 82 tokens to every session and 1,308 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-31.
