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 | $0.00046 | $0.00853 |
| Opus 5 | $0.00023 | $0.00426 |
| Sonnet 5 | $0.00009 | $0.00171 |
| Haiku 4.5 | $0.00005 | $0.00085 |
Grade A, and why
quartermaster 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 9d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Quartermaster ⚓
Quartermaster turns the current Git diff into a Skill Harbor-style changeset draft with a nautical voice.
Purpose
Use this skill when you need to:
- decide whether the release bump should be
minororpatch - draft a catchy Hero Title
- write a short Captain's Briefing
- produce release notes for
.changeset/*.md - review or correct an existing changeset draft so it matches the real branch contents
This skill is the skill-based replacement for the old bun run quartermaster workflow.
Default Workflow
- Review the current Git diff against the intended base branch.
- Default to
mainunless the user specifies another base.
- Default to
- Classify the release:
minorfor new features or significant behavior changespatchfor fixes, cleanup, docs, or narrow maintenance changes
- Generate:
- a Hero Title
- a short Captain's Briefing
- release notes in the Quartermaster format
- If the user wants a changeset file, write:
.changeset/<descriptive-name>.md
- Re-check the notes against the real diff before finalizing.
Required Structure
Use this structure unless the user explicitly asks for a different shape:
Captain's Briefing(1-2 short sentences)## ✨ New Cargo## 🛡️ Hardened Hull## 🛠️ Barnacle Scraping## 🔧 Repaired Ships## 🔭 New Skill Discoveryonly if relevant
Omit any section that has no real content.
Section intent:
## 🔧 Repaired Shipsis for user-visible repairs: fixes to CLI behavior, docs/manual behavior, distribution/packaging/install flows, or any other bug/repair a user would directly notice.## 🛠️ Barnacle Scrapingis for non-user-facing cleanup and maintenance: refactors, migrations, naming cleanups, internal plumbing fixes, and other maintenance work that is not primarily a user-noticeable repair.
Hard Rules
- Every bullet must reference a specific file, command, function, module, behavior, or user-visible change.
- Do not use vague filler like:
- "various technical improvements"
- "code improvements"
- "general enhancements"
- "better performance across different aspects"
- Do not repeat the same change in multiple sections.
- Keep the notes truthful to the current branch contents.
- If an existing draft includes unrelated changes, rewrite it rather than preserving bad content.
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.
