What is agentsmd-generator?

A documentation tool that creates AGENTS.generated.md from project rule files. AGENTS.md is a guide that tells coding agents how to work in a repository.

Use it to generate or update repository guidance for coding agents, especially after changing files in .claude/rules/.

It keeps the agent instructions in sync when project rules change or the instruction file is missing. It also adapts rules written for other coding-agent systems into a form used by several tools.

Install

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.

agentmods

npx agentmods add skills/drag88/claude-dev-framework/agentsmd-generator

Any agent

npx skills add drag88/claude-dev-framework --skill agentsmd-generator

Clone the repo

git clone --depth 1 https://github.com/drag88/claude-dev-framework

Made for: Claude Code, Codex.

Or install cdf, the plugin that ships this one along with the rest of its 13 skills, 20 commands, 11 agents, 4 hooks.

Token cost

What it costs to keep this loaded

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	$0.00020	$0.01390
Opus 5	$0.00010	$0.00695
Sonnet 5	$0.00004	$0.00278
Haiku 4.5	$0.00002	$0.00139

Security

Grade A, and why

agentsmd-generator 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md Generator Skill

Auto-generate AGENTS.generated.md from project rules. This is the Codex / GPT-5.5 counterpart to CLAUDE.md. Also picked up by Cursor, Aider, Jules, Devin, Zed, GitHub Copilot, and other coding agents that follow the AGENTS.md convention.

When to Activate

.claude/rules/ exists but no AGENTS.md or AGENTS.generated.md in project root
User asks "generate agents.md" or similar
User asks "create Codex docs" or "set up AGENTS.md"
After /cdf:rules generate completes (auto-chain alongside claudemd)
After /cdf:rules claudemd completes when AGENTS.md is also missing (sibling auto-chain)

What It Does

Executes the /cdf:rules agentsmd behavioral flow. The command definition in commands/rules.md is the single source of truth for:

What gets extracted from which rule files
Host-specific translation rules (strip @file imports, replace XML tags with prose, neutralize Claude-only tool names)
The output template and structure
Line budget and guidelines

Design Principles (Codex-aligned, from `rules-templates/agentsmd-codex-rulebook.md`)

Single source of truth, two host-tailored outputs. Same .claude/rules/ feeds both CLAUDE.md and AGENTS.md. Translate framing per host, not facts.
Target 40-60 lines. Codex caps the combined AGENTS.md chain at 32 KiB (project_doc_max_bytes), so root AGENTS.md stays slim and pushes per-package detail into nested AGENTS.md.
No @file imports. Codex parses Markdown literally — @README.md reads as the literal string, not a transclusion. Inline a 2-line summary if you need the content.
No <xml_tag> blocks. XML processing tags (<plans_instruction>, <use_parallel_tool_calls>) are Claude-specific. Codex sees the angle brackets as text.
Neutral tool vocabulary. Avoid Task tool, TeamCreate, Agent tool, subagent_type. Use subagent, parallel investigation, host skill.
Nested AGENTS.md replaces path-scoped rules. Codex does not honor paths: frontmatter. Polyglot repos push per-package conventions into <package>/AGENTS.md.
AGENTS.override.md is the overlay convention. When a sibling agent ecosystem (Cursor, Aider) needs different framing, ship it as AGENTS.override.md rather than forking the root file.
Every line passes: "Would removing this cause Codex to make mistakes?" If not, cut it.

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.

agentsmd-generator is a skill published in the GitHub repository drag88/claude-dev-framework (2 stars, last pushed 1mo ago), licensed MIT. It adds 20 tokens to every session and 1,390 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 2026-08-31.
