source-command-prepare-release

source-command-prepare-release is a skill for Claude Code from Parslee-ai/neo. It costs 20 tokens per session (1,018 once invoked), scanned A, original, Apache-2.0.

A command for preparing a new software release by checking the version, updating the changelog and related files, and building the package files.

In plain words
What is it for?
Use it before a release to validate a semantic version, review commits since the previous tag, update package metadata, synchronize installed metadata, and build wheel and source distributions.
Why use it?
It reduces the chance of inconsistent version numbers or missing release notes before publishing a new version.

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.

Security

Grade A, and why

source-command-prepare-release 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 6d 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.

Command Template

Prepare Release

Updates version numbers, CHANGELOG.md, and builds distributions for a new release.

Usage

/prepare-release 0.7.7

What This Does

  1. Validates the new version is higher than current and follows semver format
  2. Reviews commits since last release tag
  3. Updates CHANGELOG.md with new version section and categorized changes
  4. Updates the version in pyproject.toml, then runs make sync-version to propagate it to the three derived files (src/neo/__init__.py, both plugin manifests)
  5. Syncs the local editable install metadata so importlib.metadata.version("neo-reasoner") matches the new version
  6. Builds wheel and sdist distributions
  7. Reports what was done and next steps

Workflow

Step 1: Validate

  • Read current version from pyproject.toml
  • Verify new version is higher and matches format X.Y.Z
  • Check that last git tag exists (e.g., v0.7.6)

Step 2: Analyze Commits

Run git log v{last_version}..HEAD --oneline and categorize by type:

  • Fixed: Commits with "fix:" prefix or fixing bugs
  • Added: Commits with "feat:" prefix or new features
  • Changed: Commits with "refactor:" or "perf:" or improvements
  • Documentation: Commits with "docs:" prefix

Step 3: Update CHANGELOG

Add new section at top of CHANGELOG.md:

## [{new_version}] - {today's date}

### Fixed
- List of bug fixes from commits

### Added
- List of new features from commits

### Changed
- List of improvements from commits

### Documentation
- List of doc updates from commits

Step 4: Update Versions

Edit one file, then propagate:

  • pyproject.toml: change version = "X.Y.Z" — this is the source of truth.
make sync-version

That rewrites src/neo/__init__.py, .claude-plugin/plugin.json, and plugins/neo/.codex-plugin/plugin.json to match. Do not hand-edit those three: this step used to be "update the version string in all four files", and the manifests silently drifted to 0.37.0 and 0.19.0 while the package was at 0.41.0. tests/test_host_adapter_parity.py fails if they are out of sync, and python tools/sync_version.py --check reports drift without writing.

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.
