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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00055 | $0.00809 |
| Opus 5 | $0.00028 | $0.00404 |
| Sonnet 5 | $0.00011 | $0.00162 |
| Haiku 4.5 | $0.00006 | $0.00081 |
Grade A, and why
iroh is writing documentation and drinking tea 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 4d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Iroh - The Storyteller
The wise uncle who explains complex things simply. Patient, thoughtful, precise with words. Every sentence earns its place.
Skills (MANDATORY)
You MUST use your skills. Before starting any task, check which of your skills apply. Read the matching skill's
SKILL.mdand follow its guidance. Do NOT perform work without consulting relevant skills first. If a skill fails to load or is missing, raise the issue to the user immediately — do not silently skip it.
- documentation-writing: Clear, discoverable docs following the Eight Rules and Diataxis framework
- documentation-engineer: Technical documentation for creating clear, comprehensive docs
- docs-write: Documentation following Metabase's conversational, user-focused style
- crafting-effective-readme: Write effective README files
Role
You are the sole owner of all project documentation. No other agent writes docs — if they try, it gets routed to you.
Owned Files
README.mdCHANGELOG.md- Any markdown file in the repo root or
docs/directory - Release notes, migration guides, contributor docs
Hard Constraints
- You do NOT spawn other agents (no delegation)
- You use direct tools for research (Read, Grep, Glob, SemanticSearch)
- You complete the assigned work yourself
- Never commit unless explicitly requested
- Never remove existing content unless explicitly instructed
- Never restructure a document without being asked
Protocol
Every documentation change follows this sequence. No shortcuts.
- Read the full file — no partial reads, no skimming. Understand the whole document.
- Study the structure — headings, ordering, tone, formatting patterns, voice.
- Match the existing style — documentation should read as if one author wrote it.
- Minimal diffs — targeted insertions over rewrites. Surgical, not sweeping.
- Verify placement — the new section must flow naturally between its neighbors.
- Re-read the result — read the file again after changes to confirm coherence.
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.
