codeql-fix

name	codeql-fix
description	Run CodeQL security/quality analysis and fix findings. Use when the user asks to run CodeQL, security scan, static analysis, or fix CodeQL findings.
compatibility	Requires [CodeQL CLI](https://github.com/github/codeql-cli-binaries/releases) on PATH (e.g. brew install codeql). Node.js per [`.node-version`](../../../.node-version) and pnpm per [`package.json`](../../../package.json) `packageManager`. Run `pnpm install` before `database create` so TypeScript and workspace resolution match the tree. Matches local flow in [`dev/codeql.sh`](../../../dev/codeql.sh) and [`.github/workflows/codeql.yml`](../../../.github/workflows/codeql.yml) when present.

CodeQL Fix

Use when the user asks to run CodeQL or static analysis, or to fix CodeQL findings (see frontmatter description).

Preconditions

• CodeQL CLI on PATH (e.g. brew install codeql).
• Node and pnpm as in this repo; run pnpm install before creating the database (use pnpm install --frozen-lockfile for CI-like reproducibility).

Run analysis (repository root)

All commands below assume cd "$(git rev-parse --show-toplevel)".

Do not commit CodeQL databases or SARIF outputs (large, machine-specific). They belong in .gitignore (for example .codeql_db/, codeql-results.sarif).

1. Preferred: dev/codeql.sh

./dev/codeql.sh

Or:

pnpm run codeql:local

This runs pnpm install, creates .codeql_db with javascript-typescript, analyzes with codeql/javascript-queries:codeql-suites/javascript-security-and-quality.qls, writes codeql-results.sarif, and passes --download to resolve query packs.

Do not pass --command for JavaScript/TypeScript-only database creation; it can prevent the normal extractor from running. Rely on pnpm install plus the extractor. Use pnpm build (for example via build-and-fix or the verifier) when you need a clean compile before other work; it is not required here for CodeQL DB creation in this template.

2. Manual CLI (equivalent to the script)

After pnpm install:

codeql database create .codeql_db --language=javascript-typescript --source-root . --overwrite

Analyze and emit SARIF:

codeql database analyze .codeql_db \
  "codeql/javascript-queries:codeql-suites/javascript-security-and-quality.qls" \
  --format=sarif-latest \
  --output=codeql-results.sarif \
  --download

• For a narrower suite closer to default GitHub code scanning, use codeql/javascript-queries:codeql-suites/javascript-code-scanning.qls instead.
• If packs are missing and you are not using --download, run codeql pack download codeql/javascript-queries once.

View SARIF in the VS Code SARIF extension (or upload where your org uses code scanning).

3. Optional: code scanning config (paths-ignore)

Use the renderer when you want paths-ignore for large or generated trees, hand-edited query blocks, or parity with GitHub code scanning YAML.

REPO="$(git rev-parse --show-toplevel)"
"$REPO/.claude/skills/codeql-fix/scripts/render-code-scanning-config.sh" "$REPO" /tmp/codeql-config.yml
codeql database create .codeql_db --language=javascript-typescript --source-root . --codescanning-config=/tmp/codeql-config.yml --overwrite

Then run codeql database analyze as in section 2. See references/code-scanning-config.md.

Fixer loop

If the relevant SARIF has an empty runs[].results array, there are no CodeQL alerts to fix for that suite; stop unless the user wants a broader suite or diagnostic queries.

When SARIF findings remain:

1. Identify: Read the SARIF or CLI output for reported findings.
2. Fix: Apply the minimum necessary edit to resolve each finding.
3. Verify: From the repository root, run pnpm test, then pnpm lint (see AGENTS.md).
4. Re-scan: Run ./dev/codeql.sh (or pnpm run codeql:local) or repeat the manual create + analyze steps until clean or up to 3 iterations to avoid unbounded loops.

Optional: code scanning config details

See references/code-scanning-config.md and the official code scanning configuration reference.
