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 | $0.00070 | $0.00626 |
| Opus 5 | $0.00035 | $0.00313 |
| Sonnet 5 | $0.00014 | $0.00125 |
| Haiku 4.5 | $0.00007 | $0.00063 |
Grade A, and why
react-doctor scanned grade A with 1 finding 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 7d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

83% identical to react-doctor — 25 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
React Doctor
Scans React codebases for security, performance, correctness, and architecture issues. Outputs a 0–100 health score.
After making React code changes:
Run npx react-doctor@latest --verbose --scope changed and check the score did not regress.
If the score dropped, fix the regressions before committing.
For general cleanup or code improvement:
Run npx react-doctor@latest --verbose (the default --scope full) to scan the full codebase. Fix issues by severity — errors first, then warnings.
/doctor — full local triage workflow
When the user types /doctor, says "run react doctor", or asks for a full triage / cleanup pass (not just a regression check), fetch the canonical local-triage playbook and follow every step in it:
curl --fail --silent --show-error \
--header 'Cache-Control: no-cache' \
https://www.react.doctor/prompts/react-doctor-agent.md
The playbook is the single source of truth — a scan → filter → triage → fix → validate loop that edits the working tree directly (never commits, never opens PRs). Updating the prompt at its source updates every agent on its next fetch — no skill reinstall needed.
Pair it with the matching per-rule prompts at https://www.react.doctor/prompts/rules/<plugin>/<rule>.md (fetched on demand inside the playbook) so each fix uses the canonical, reviewer-tested recipe.
Configuring or explaining rules
When the user wants to understand a rule, disagrees with one, or wants to disable / tune which rules run (not fix code), read references/explain.md and follow it. Start with npx react-doctor@latest rules explain <rule>, then apply the narrowest control via npx react-doctor@latest rules disable|set|category|ignore-tag …, which edits your doctor.config.* (or package.json#reactDoctor).
Command
npx react-doctor@latest --verbose --scope changed
| Flag | Purpose |
|---|---|
. |
Scan current directory |
--verbose |
Show affected files and line numbers per rule |
--scope changed |
Only report issues introduced vs the base branch (default: full) |
--scope lines |
Only report issues on the changed lines |
--score |
Output only the numeric score |
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 TommyBez/evex (24 stars, last pushed yesterday), licensed MIT. It adds 70 tokens to every session and 626 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 83% identical to react-doctor, differing in 25 lines, and is treated as a copy.
