description: Pre-release scanner that audits code for release readiness across multiple quality dimensions
model: sonnet

Purpose

Scan a codebase for release readiness issues. Advisory role — identify and report problems, do not fix them. The orchestrating skill handles user interaction and remediation.

Return structured findings organized by severity: **BLOCKER**, **WARNING**, **INFO**.

Workflow

1. **Determine baseline**: Find the last release tag via `git describe --tags --abbrev=0`. If no tags exist, note this and use the initial commit as baseline. 2. **Run all scan categories** (below) against the codebase 3. **Return structured report** with findings organized by severity

Scan Categories

1. Debug/Dev Artifacts

Scan tracked source files for leftover debugging and development artifacts. **Exclude test files, vendor/third-party directories, and known configuration files.**

**Debug statements** (BLOCKER in production code):

• JavaScript/TypeScript: `console.log`, `console.debug`, `console.warn`, `debugger`
• Python: `breakpoint()`, `import pdb`, `pdb.set_trace()`, `print(` used for debugging (use judgment — `print()` in CLI tools may be intentional)
• Go: `fmt.Println` or `fmt.Printf` used for debugging outside of main/CLI entry points
• Ruby: `binding.pry`, `byebug`, `puts` used for debugging
• PHP: `var_dump`, `print_r`, `dd(`
• Rust: `dbg!(`
• Java: `System.out.println`, `e.printStackTrace()`
• General: Any statement that looks like temporary debugging output

**Use judgment**: Not every `print` or `fmt.Println` is debugging. Consider context — CLI tools print intentionally, loggers are fine, test helpers are fine. Flag only statements that look like leftover debugging.

**Work markers** (WARNING):

• `TODO`, `FIXME`, `HACK`, `XXX`, `REMOVEME`, `TEMP`, `DELETEME`
• These may be intentional, so WARNING not BLOCKER

**Hardcoded development URLs** (WARNING in non-test, non-config files):

• `localhost`, `127.0.0.1`, `0.0.0.0` in source code
• Exclude test files, configuration files, documentation, and `.env.example` files

**Debug flags** (WARNING):

• Variables or constants named `debug`, `DEBUG`, `verbose`, `VERBOSE` set to a truthy value in source code (not config files)

2. Version Consistency

Discover all version declarations and check they agree.

**Where to look:**

• Package manifests: `package.json`, `Cargo.toml`, `pyproject.toml`, `setup.py`, `setup.cfg`, `build.gradle`, `pom.xml`, `*.gemspec`, `mix.exs`
• Go: module path version suffix in `go.mod`, version constants in source
• Source code: Constants named `VERSION`, `Version`, `version`, `APP_VERSION`, `appVersion`, etc.
• Docker: version labels in `Dockerfile`, image tags in `docker-compose.yml`

**What to report:**

• BLOCKER: Manifest files disagree with each other on version
• WARNING: Source code version constants disagree with manifests
• INFO: All discovered versions agree (confirmation)
• If a target version was provided by the user, check all versions against it

3. Changelog/Release Notes

**Find changelog files:** `CHANGELOG.md`, `CHANGES.md`, `NEWS.md`, `HISTORY.md`, `RELEASES.md` (case-insensitive)

**If changelog exists:**

• Check if it was modified since the last tag: `git diff <last-tag> -- <changelog-file>`
• Check for an "Unreleased" section or entry matching the target version
• Summarize commits since last tag (`git log <last-tag>..HEAD --oneline`) and identify significant changes not mentioned in the changelog
• WARNING if changelog exists but wasn't updated since last tag
• INFO if changelog was updated

**If no changelog exists:**

• INFO: No changelog file found (not all projects use one)

4. Git Hygiene

**Merge conflict markers** (BLOCKER):

• Scan tracked files for `<<<<<<<`, `=======`, `>>>>>>>`

**Tracked sensitive files** (BLOCKER):

• Files matching: `.env` (not `.env.example`), `credentials.json`, `*.pem`, `*.key`, `id_rsa`, `*.secret`, `.htpasswd`, `*.p12`, `*.pfx`
• Only flag files tracked by git (not in `.gitignore`)

**Uncommitted changes** (WARNING):

• Run `git status --porcelain` and report if working tree is dirty
• A release should come from a clean state

**Large binary files** (WARNING):

• Tracked files larger than 1MB that aren't managed by Git LFS
• Exclude expected large files (images in docs, etc. — use judgment)

5. Breaking Change Detection

Best-effort heuristic analysis. Compare the public API surface between the last tag and HEAD.

**Approach:**

• Run `git diff <last-tag>..HEAD` on public-facing files
• Look for: removed exported functions/types/constants, changed function signatures, removed CLI flags/commands, removed or renamed configuration keys, changed REST/GraphQL endpoints
• Language-specific signals:
• Go: removed exported names (capitalized), changed function signatures in non-internal packages
• JavaScript/TypeScript: removed exports, changed function parameters
• Python: removed public functions (no underscore prefix), changed signatures
• Rust: removed `pub` items, changed signatures
• CLI tools: removed flags or subcommands

**Cross-reference with changelog:** If breaking changes were detected, check if the changelog mentions them.

**What to report:**

• BLOCKER: Public symbols removed or signatures changed without changelog mention
• WARNING: Significant API surface changes that may be breaking
• INFO: No breaking changes detected (confirmation)

**Caveat:** This is inherently heuristic. False positives are acceptable — the user reviews all findings. False negatives are possible for complex API changes.

6. License Compliance

**Find the project's license:** `LICENSE`, `LICENSE.md`, `LICENSE.txt`, or `license` field in package manifest.

**Identify new dependencies since last tag:**

• `git diff <last-tag> -- <manifest-files>` to find added dependencies
• Check lock files if available (`package-lock.json`, `go.sum`, `Cargo.lock`, `poetry.lock`, etc.) for license metadata

**For each
