reactuse: Command for Claude Code

.claude/commands/pre-pr.md

pre-pr is a command for Claude Code from childrentime/reactuse. It costs 21 tokens per session (309 once invoked), scanned A, original, Unlicense.

A pre-pull-request checklist for the ReactUse repository. A pull request is a proposed code change that others review before it is merged.

In plain words
What is it for?
Use it to check the current Git changes, run relevant linting and tests, update the hook registry when needed, scan for debug statements, and verify documentation links.
Why use it?
It catches lint errors, failing tests, stale documentation indexes, debug code, and broken links before review begins.

Command for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md.

This is childrentime/reactuse's own configuration. It tells Claude Code how to work on reactuse itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything reactuse configures →

Token cost

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00021 $0.00309
Opus 5.5 $0.00008 $0.00124
Sonnet 5.5 $0.00004 $0.00062

Security

Grade A, and why

pre-pr 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 2mo 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

Run the pre-PR checklist for ReactUse. Work only against the current diff — fix issues this change introduced, not pre-existing warnings elsewhere.

  1. Scope the diff. git status and git diff --stat to see what changed.

  2. Lint. pnpm lint. Fix only failures in files you touched.

  3. Test. If anything under packages/core/src changed, run pnpm --filter @reactuses/core test (or scope to the affected hooks). All green.

  4. Registry sync. If any .mdx under packages/website-astro/src/content/docs* changed, run bash scripts/generate-hook-registry.sh and include the updated scripts/hook-registry.json in the change.

  5. Debug-log scan. Grep your diff for stray console.log / debugger / .only( left in. Remove them. (Intentional isDev console.error validation stays.)

  6. Link check. If docs or a blog post changed, verify every reactuse.com hook link against scripts/hook-registry.json (see CLAUDE.md).

Report a short pass/fail summary per step. Do not commit or push unless asked.

Changes

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.
