+description: Use when pre-commit hooks pass locally but CI fails on formatting (prettier --check, cargo fmt --check), or when adding/modifying git hooks that enforce code style. Also use when a formatting failure in one CI job cascades to skip downstream lint/test jobs.
+---
+
+# CI Format Guard
+
+Pre-commit hooks that pass locally but CI fails on formatting mean the hook checks but doesn't fix. CI formatting is the last line of defense — it should never be the first.
+
+## Core Principle
+
+**Hooks auto-fix, not just check.** If a hook detects a formatting issue it can fix, it should fix it — not report it and block.
+
+## Pattern: Auto-Fix + Re-Stage
+
+```bash
+# ❌ BAD: Checks but doesn't fix — CI will fail
+cargo fmt --manifest-path desktop/src-tauri/Cargo.toml -- --check $changed_rs || exit 1
+
+# ✅ GOOD: Auto-fixes AND propagates failure for unfixable errors
+cargo fmt --manifest-path desktop/src-tauri/Cargo.toml -- $changed_rs || exit 1
+echo "$changed_rs" | xargs -r git add
+```
+
+The `|| exit 1` stays — cargo fmt can fail for unfixable reasons (missing toolchain, malformed syntax). But formatting issues get auto-fixed and re-staged.
+
+## Quick Reference
+
+| Workspace | Format command (auto-fix) | Verify command (CI) |
+|-----------|--------------------------|---------------------|
+| server (TS/Vue) | `pnpm --filter drop exec prettier --write <file>` | `pnpm --filter drop exec prettier --check .` |
+| Rust (any) | `cargo fmt -- <file>` | `cargo fmt -- --check` |
+| YAML/MD/JSON | `pnpm --filter drop exec prettier --write <file>` | Same as server |
+
+## jq Defensive Patterns
+
+jq in CI scripts crashes on null/non-numeric values. Always guard:
+
+```bash
+# ❌ BAD: crashes on null
+.value | tonumber > 0
+
+# ✅ GOOD: fallback + try/catch guards against non-numeric
+(.value // "0") | (try tonumber catch 0) > 0
+```
+
+## Bash Pipeline Traps
+
+```bash
+# ❌ BAD: while loop runs in subshell — COMMENT_BODY mutations lost
+echo "$data" | jq -c '.[]' | while read -r entry; do
+  COMMENT_BODY+="processed"
+done
+
+# ✅ GOOD: process substitution keeps while in parent shell
+while read -r entry; do
+  COMMENT_BODY+="processed"
+done < <(echo "$data" | jq -c '.[]')
+```
+
+## SonarCloud Coverage Disconnect
+
+`new_uncovered_lines` = 0 but `new_coverage` = 0% happens when changed lines aren't classified as "coverable" (imports, type annotations, comments). Include BOTH metrics in coverage gap detection:
+
+```jq
+select(
+  (.measures[]? | select(.metric == "new_uncovered_lines") | (.value // "0") | tonumber > 0)
+  or
+  (.measures[]? | select(.metric == "new_coverage") | .value // "100") == "0.0"
+)
+```
+
+## Pre-commit Hook Structure
+
+```text
+1. lint-staged (prettier --write, eslint --fix) → auto-fixes JS/TS/Vue → re-stages
+2. cargo fmt → auto-fixes Rust → re-stages
+3. typecheck → validates (read-only, no fixes)
+4. shellcheck → validates (read-only)
+5. fallow audit → validates (read-only, gate-only)
+```
+
+Auto-fixers first, validators last. Nothing unfixed leaves the hook.

+description: Use when PR has 10+ open review threads from automated bots (OCR, CodeRabbit, Sourcery) that need batch evaluation and resolution, or when pre-push hook warnings show unresolved threads accumulating across commits.
+---
+
+# PR Review Cleanup
+
+Automated review bots (OCR, CodeRabbit, Sourcery) fire on every push. Each push creates new threads. Without cleanup, threads accumulate exponentially — every new scan finds existing threads plus new ones.
+
+## Core Pattern
+
+```
+push → new review run → new threads → unresolved count grows
+                                  ↓
+hook warns (advisory) → agent reads JSON → batch evaluate → resolve all
+```
+
+## Quick Reference
+
+| Step | Command |
+|------|---------|
+| Pull unresolved threads | `gh api graphql -f query='...reviewThreads...' -F pr=N` |
+| Filter for JSON | `jq 'select(.isResolved == false)'` |
+| Resolve thread | `gh api --method PATCH repos/:owner/:repo/pulls/:pr/comments/:id -f state=CLOSED` (or use MCP `resolve_thread` with PRRT_xxx ID) |
+| Post summary | `gh pr comment N --body "All N threads evaluated: ..."` |
+
+## GraphQL Query (get PRRT_xxx IDs — cursor-paginated)
+
+```graphql
+query($owner:String!, $repo:String!, $pr:Int!, $cursor:String) {
+  repository(owner:$owner, name:$repo) {
+    pullRequest(number:$pr) {
+      reviewThreads(first:100, after:$cursor) {
+        nodes {
+          id isResolved isOutdated
+          comments(first:1) {
+            nodes { author { login } body path line }
+          }
+        }
+        pageInfo { hasNextPage endCursor }
+      }
+    }
+  }
+}
+```
+
+Loop until `hasNextPage` is false. The `first:100` cap silently drops threads on large PRs; cursor pagination is mandatory.
+
+The returned `id` is the PRRT_xxx GraphQL node ID used for resolution.
+
+## Batch Resolution Pattern
+
+1. Pull all threads into JSON
+2. Filter `isResolved == false`
+3. Categorize: *fix now* (bug/security), *skip with reason* (nitpick/false-positive), *already fixed* (commit addressed)
+4. Post one summary comment explaining disposition of all threads
+5. Resolve all threads via `resolve_thread` API (one call each)
+6. Verify with `pre-push` hook — count should be 0
+
+## Common Thread Categories
+
+| Category | Action |
+|----------|--------|
+| Bug / security / functional | Fix in code, resolve |
+| OCR false positive (Nitro auto-imports, hadolint suppression) | Skip with explanation, resolve |
+| Duplicate from multiple OCR runs | Resolve (one run's copy), other auto-resolved |
+| Nitpick / cosmetic | Skip with reason, resolve |
+| Positive feedback ("good improvement") | Acknowledge, resolve |
+| Pre-existing (not introduced by PR) | Skip, resolve |
+| Stale / outdated (code already changed) | Resolve as outdated |
+
+## Red Flags
+
+- Resolving threads without reading them — OCR finds real bugs
+- Leaving "good improvement" comments unresolved — clutter
+- Not posting a summary comment — future reviewers need context on why threads were closed
+- Using `--no-verify` to skip the hook instead of cleaning threads
+
+## Pre-push Hook Integration
+
+The pre-push hook at `.husky/pre-push` queries unresolved threads. JSON output between `## PR_REVIEW_THREADS_START` / `## PR_REVIEW_THREADS_END` markers. Agent should parse this and act BEFORE pushing — clean threads first, then push clean.
