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 | $0.00135 | $0.01393 |
| Opus 5 | $0.00068 | $0.00696 |
| Sonnet 5 | $0.00027 | $0.00279 |
| Haiku 4.5 | $0.00014 | $0.00139 |
Grade A, and why
js-docs-sync 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 2d 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 — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.
JS Package Docs Sync
Verify and update hand-written docs/ documentation in a JS package so it stays
accurate against the actual source code. These docs ship in the npm package (via
the files field in package.json) for coding agents to read from node_modules.
When This Matters
The docs are the contract between the package and coding agents that consume it. Stale signatures, missing exports, or invalid examples mean agents write broken code. Source code is the single source of truth — docs must reflect it exactly.
Workflow
Step 1: Identify the Package
Determine which JS package to sync. If not clear from context, check which
packages have a docs/ directory:
find js/packages -maxdepth 2 -name docs -type d
If only one package has docs, use it. Otherwise ask the user.
Step 2: Understand the Doc Structure
Read docs/README.md in the target package. It contains:
- A Documentation Guide table mapping each doc file to its topic area
- An All Exports at a Glance section listing every public export
- A Source Code Map showing which source files contain what
This is your roadmap — it tells you what each doc file covers and where to look in the source to verify it.
Step 3: Identify What Changed
If this is triggered by source edits, focus on the changed files:
git diff --name-only HEAD~1 -- js/packages/<package>/src/
Map changed source files to the doc files that cover them (using the Source Code Map in README.md). You only need to re-verify the affected docs.
If this is a full review (user asks to "check all docs"), verify everything.
Step 4: Verify Each Doc File
For each doc file that needs checking, compare it against the source code. Check these things in order:
4a. Export Completeness
Read the barrel files (src/index.ts and any sub-module index.ts files) to get
the full list of public exports. Compare against what's listed in docs/README.md
under "All Exports at a Glance". Flag any export that is:
- In source but missing from docs (new export, needs documenting)
- In docs but not actually exported (removed or renamed, needs removing from docs)
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.

js-docs-sync is a skill published in the GitHub repository Arize-ai/openinference (1,186 stars, last pushed 3d ago), licensed Apache-2.0. It adds 135 tokens to every session and 1,393 once invoked, about $0.0007 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 2026-08-30.
