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 | $0.00014 | $0.02819 |
| Opus 5.5 | $0.00006 | $0.01128 |
| Sonnet 5.5 | $0.00003 | $0.00564 |
| Haiku 4.5 | $0.00001 | $0.00282 |
Grade A, and why
improve-doc 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 1mo 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 — 381 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Improve Doc
Analyze an existing markdown document, classify sections by Diataxis type, identify issues, and interactively refine each section.
Arguments
- Path: Path to the markdown document to improve (required)
Workflow Overview
Invoke the improve-doc skill with a document path, e.g. improve-doc docs/guides/getting-started.md.
The skill runs in two phases:
- Analysis Phase: Parse document, classify sections, identify issues
- Refinement Phase: Interactive loop to improve each section
Gates
Hard sequencing — advance only when the pass condition is met (artifact or explicit user input, not assumed).
Before Phase 2 (refinement):
- Read — Full contents of the file at Path are loaded.
- Pass: Enumerated sections (from
#/##/###headings) cover every heading in the file; titles match the source.
- Pass: Enumerated sections (from
- Core skill — docs-style is loaded (or its path read) before classification.
- Pass: Analysis output reflects at least one concrete principle from that skill (name it or quote briefly).
- Handoff — User saw an analysis summary (template in Step 5 or equivalent) and entered
startto begin refinement, orabortto exit.- Pass: If
abort, no writes to Path. Ifstart, proceed to Phase 2.
- Pass: If
Before overwriting the file (Phase 2, Step 4):
- Choices — Every section with open issues has a terminal outcome: applied
yes, unchangedskip, ormodifyloop finished withyesorskip.- Pass: No section left in a pending
modifystate unless the user aborted the whole session (then do not write).
- Pass: No section left in a pending
- Skips — Content for every
skipmatches the original section text (copy preserved, not paraphrased).- Pass: Full block equality check against the initial read (line-for-line, including whitespace).
- Write — Only after the above.
- Pass: Single save to Path; completion report notes backup or major restructure if applicable (Rules).
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.

improve-doc is a skill published in the GitHub repository existential-birds/beagle (82 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 14 tokens to every session and 2,819 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-16.
