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 | $0.11955 | $0.11955 |
| Opus 5 | $0.05978 | $0.05978 |
| Sonnet 5 | $0.02391 | $0.02391 |
| Haiku 4.5 | $0.01196 | $0.01196 |
Grade A, and why
daodan 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 today.
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
94% identical to daodan AGENTS.md — 20 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 — 248 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Daodan
The Daodan is the symbiote that augments its host. This repository is the Daodan of coding agents: one marketplace of agents, skills, and workflows that augment a base model into a specialized toolkit covering development workflows, code quality, AI tooling, scraping, trading, observability, and more. It ships to three hosts from one source. Remote: acaprino/daodan on GitHub.
Project structure
plugins/<name>/ is a plugin's content kernel, and it is the only hand-authored plugin source alongside adapters/. Each kernel holds plugin.toml (the neutral control plane), roles/ (agent bodies), workflows/ (entry-point bodies plus one TOML sidecar each), skills/, contracts/ and policies/. Markdown is always the behaviour; TOML is always declarative metadata and never carries a prompt.
adapters/<host>/ is what one host can do: capabilities.toml binds every neutral capability to a host mechanism, coordination.toml orders the coordination strategies that host supports, layout.toml says where each component lands in its packages and what the two Claude placeholders a kernel may write (${CLAUDE_PLUGIN_ROOT}, $ARGUMENTS) become on that host, templates/ holds the harness wrappers, policies/ holds this host's implementation of a neutral policy, and overrides/ holds fingerprinted semantic divergences.
Everything under exports/ and all three root marketplace manifests are generated. scripts/daodan_build.py compiles kernels plus adapters into exports/claude/, exports/copilot/ and exports/codex/, and into .claude-plugin/marketplace.json, .github/plugin/marketplace.json and .agents/plugins/marketplace.json. Never hand-edit them; edit the kernel and rebuild.
AGENTS.md and the four repository workflow skills under .agents/skills/ are native Codex adaptations of this file and .claude/skills/. Generate them with python scripts/sync_codex_instructions.py; --check is the parity gate. Edit the Claude-side canonical copies, then run the synchronizer. The transformation is deliberately limited to instruction paths, cache paths, install commands and the host-relative downstream description.
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.

daodan CLAUDE.md is an instructions file published in the GitHub repository acaprino/daodan (8 stars, last pushed yesterday), licensed MIT. It adds 11,955 tokens to every session, about $0.0598 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to daodan AGENTS.md, differing in 20 lines, and is treated as a copy.
