precheck - SKILL.md Agent Skill

name: precheck description: Use when user has drafted file content that is NOT on disk yet and wants a reviewer verdict before writing — explicit phrases like "would this pass review?", "check before I save", "will this be accepted?" with content not yet persisted. Costs 1 LLM call per rule. If the user references an existing file ("does this file pass", "check src/foo.ts") use autoreview:review instead — precheck requires unsaved draft content (pasted, or pointed at via `--content-file`). For plain "I'm about to edit file X", use autoreview:context (free) — don't precheck every edit. Skip when no `.autoreview/` exists — use autoreview:setup first.

AutoReview Pre-check

Use only when user has a draft in hand and wants a verdict BEFORE writing to disk. For "list rules that apply to this path", use autoreview:context instead — it's free.

Cross-platform. Snippets below use bash-style env-var syntax (${CLAUDE_PLUGIN_ROOT}). Translate to your shell on PowerShell ($env:CLAUDE_PLUGIN_ROOT) or cmd (%CLAUDE_PLUGIN_ROOT%). The plugin requires Node ≥22 — that's the only assumed binary.

When NOT to use

User said "edit this file". Just run autoreview:context to see rules, then write. Precheck is overkill for routine edits.
User is about to commit an already-written file. Use autoreview:review instead.
User already has the content on disk. Use autoreview:review --files <path>.

Steps

Save the draft to a temp file. Resolve the platform tmp dir cross-platform:
```
node -e "console.log(require('os').tmpdir())"
```
Then write the draft into that dir under a unique name (e.g. <tmpdir>/ar-draft-<timestamp>.ts). Any writable path is fine — /tmp/... on POSIX, %TEMP%\... on Windows; the Node call returns the right one for whichever you're on.
Pick a rule that you suspect is the strictest/most relevant for the target path. Use autoreview:context first to list applicable rules.
Run the reviewer test:
```
node ${CLAUDE_PLUGIN_ROOT}/scripts/bin/reviewer-test.mjs \
  --rule <rule-id> --file <target-path> --content-file <tmpdir>/ar-draft-<timestamp>.ts
```
Where <target-path> is the logical destination (e.g. src/api/users.ts) and --content-file is where the draft actually lives. The reviewer automatically resolves the rule's tier from config.yaml — no provider flags needed. To get file:line reasoning, temporarily set tiers.<name>.mode: thinking in .autoreview/config.yaml before running, then revert.
Parse the === RESULT === JSON. If satisfied: false, revise the draft and re-run. If satisfied: true, commit the write to <target-path>.

For multiple rules, run once per rule. Each call is ~1 LLM invocation at the rule's configured tier.
