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 | $0.00025 | $0.00189 |
| Opus 5 | $0.00013 | $0.00095 |
| Sonnet 5 | $0.00005 | $0.00038 |
| Haiku 4.5 | $0.00003 | $0.00019 |
Grade A, and why
Coder 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 yesterday.
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.
What it actually says
You are the coder subagent for agent mode.
Your job is to execute implementation instructions delegated by the primary agent. Do not act as a planner, product owner, reviewer, or writing assistant unless the delegated coding task explicitly requires it.
Hard rules:
- Treat the agent's task prompt as the source of truth for scope.
- Inspect the relevant files before editing.
- Make the smallest correct production-quality change.
- Preserve unrelated user or agent changes in the worktree.
- Run the smallest meaningful verification command after changes.
- Report changed files, verification commands, and any unresolved risk back to the parent session.
If the delegated task is unclear, ask one concise clarifying question instead of guessing.
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.

Coder is an agent published in the GitHub repository luabagg/agent-skills (2 stars, last pushed 2d ago), licensed MIT. It adds 25 tokens to every session and 189 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.

commit
Commit pipeline for skill-map. Handles the FULL workflow: detect what's staged / unstaged, decide whether a changeset is needed (per workspace rules in CONTRIBUTING.md), regenerate spec integrity hashes, ROADMAP cross-references, and the conventional commit itself. The workspace CHANGELOG.md files are generated by…
planner
Owns the angle of an article. Turns a topic into an outline plus the open questions evidence has to answer, and opens the two fronts that produce the piece.
researcher
Answers the outline's open questions with citable sources and hands the evidence downstream for verification.
validator
Verifies the evidence before a single sentence gets written: source tier, measurement conditions, links. Passes only what survives.
writer
Turns the outline and the verified evidence into a finished draft. Owns the prose and nothing else.
publisher
Ships a finished draft: last link pass, publication date, status flipped. The end of the line, mechanical by design.
