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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00051 | $0.00528 |
| Opus 5.5 | $0.00020 | $0.00211 |
| Sonnet 5.5 | $0.00010 | $0.00106 |
| Haiku 4.5 | $0.00005 | $0.00053 |
Grade A, and why
react-doctor 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.
What it actually says
React Doctor
Workflow
- Extract the target path from the user's message. If no path is provided, default to
packages/map. - Derive the base filename by replacing
/with-in the path (e.g.packages/map→packages-map). - Create the output directory if it doesn't exist:
mkdir -p _react-doctor/output
- Run React Doctor and capture output in memory only — do not save the raw scan to disk:
if command -v react-doctor &> /dev/null; then
react-doctor <PATH>
else
npx react-doctor@latest <PATH>
fi
- Parse all issues from the output.
- Group issues by rule type (e.g.
react/jsx-key,react-hooks/exhaustive-deps). Within each rule group, sort by ease of fixing: quick fixes first, involved last. - Write the checklist to
_react-doctor/output/<BASENAME>-review.md:
# React Doctor Review — packages/map
## react/jsx-key
> Missing `key` prop in list renders — mechanical fix, no logic impact
- [ ] `src/components/MapLayer.jsx:67` — Missing `key` prop in list render
- [ ] `src/components/Legend.jsx:34` — Missing `key` prop in list render
## react-hooks/exhaustive-deps
> Missing or incorrect hook dependency arrays — may require reasoning about effect scope
- [ ] `src/components/Map.jsx:42` — useEffect missing dependency: `data`
## react-hooks/rules-of-hooks
> Hook usage violations — touch component logic, review carefully
- [ ] `src/components/Legend.jsx:18` — Hook called conditionally
---
X issues across Y rule types.
- Tell the user the review file has been written to
_react-doctor/output/<BASENAME>-review.md. - Tell the user to check off issues in the review file, then run the
react-doctor-fixskill to work through them one by one.
Do not suggest or provide any fixes at this stage. Do not create any other files.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

react-doctor is a skill published in the GitHub repository CDCgov/cdc-open-viz (55 stars, last pushed today), licensed Apache-2.0. It adds 51 tokens to every session and 528 once invoked, about $0.0002 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 2026-08-30.
