README

github-release-skill

Claude Code skill plugin for safe, automated GitHub releases with supply chain security.

Problem

AI coding agents (Claude Code, Copilot, etc.) naturally reach for a bare gh release create when asked to "create a release". This:

1. Creates lightweight unsigned tags instead of signed annotated tags
2. Works with GitHub immutable releases: where the repository setting is on, a published release locks its tag and assets and burns the tag name (no recovery); the setting is per repository, see references/immutable-releases.md
3. Bypasses CI pipelines that handle SBOMs, attestations, and signing

This skill prevents these mistakes structurally via hooks and provides the correct release orchestration.

Features

• Guard hooks: Block gh release delete, gh release edit beyond notes, a gh release create that could create the tag (i.e. without --verify-tag), and lightweight tag creation — at the tool level
• Ecosystem detection: Auto-detect project type (TYPO3, PHP, Node.js, Go, Python, Rust, skill repos)
• Version management: Suggest next semver version from conventional commits, update all version files
• Release orchestration: Version bump PR → merge → signed tag → CI handles the rest
• Health checks: Validate release workflow, tag integrity, supply chain security
• CI templates: Release workflow templates with SBOM, cosign, attestation support

Commands

Command	Description
/release	Full release: detect, bump, PR, tag, CI
/release-prepare	Version bump PR only (tag manually)
/release-status	Release health check

Installation

Claude Code Marketplace (recommended)

Installed automatically via the Netresearch marketplace.

Composer

composer require --dev netresearch/github-release-skill

npm (Node Projects)

npm install --save-dev \
  @netresearch/agent-skill-coordinator \
  github:netresearch/github-release-skill

Requires @netresearch/agent-skill-coordinator, which discovers the skill in node_modules and registers it in AGENTS.md via a postinstall hook. For pnpm, also allowlist the coordinator's postinstall:

{
  "pnpm": {
    "onlyBuiltDependencies": ["@netresearch/agent-skill-coordinator"]
  }
}

Limitation: This installation method only registers the skill's SKILL.md content (procedural knowledge that the agent reads). The slash commands (/release, /release-prepare, /release-status) and the PreToolUse guard hooks defined in .claude-plugin/ are not loaded by Claude Code when the skill is installed via npm — those require Claude Code's plugin mechanism. To get the full skill (slash commands + guard hooks + procedural knowledge), install via the Claude Code Marketplace instead.

Manual

Download the latest release and extract to ~/.claude/plugins/.

How It Works

1. Hooks intercept dangerous commands before execution
2. Ecosystem detection finds all version files in the project
3. Version bump updates all files and promotes CHANGELOG
4. PR workflow ensures changes go through review and CI
5. Signed tag (git tag -s) triggers the release workflow
6. CI pipeline creates the GitHub release with SBOMs, signatures, and attestations

Supported Ecosystems

Ecosystem	Version Files
TYPO3	ext_emconf.php, composer.json, Documentation/guides.xml
PHP/Composer	composer.json
Node.js	package.json, package-lock.json
Go	Tags only (no version files)
Python	pyproject.toml, setup.py
Rust	Cargo.toml
Skill repos	plugin.json, SKILL.md metadata

Governance and policies

This repository follows the Netresearch organisation policies:

• Governance: ownership, roles, how decisions are made and disputes resolved, and continuity.
• Roadmap: planned and explicitly excluded work for the coming year.
• Handling of dependency and code analysis findings: thresholds, deadlines and the exception process for dependency (SCA) and static analysis (SAST) findings.
• Secret management: how CI and release credentials are stored, accessed and rotated.
• Access roster: who holds administrative access to this repository and the organisation.

The security assurance case for this skill (threat model, trust boundaries, countermeasures and limits) is in docs/SECURITY-ASSURANCE.md.

Checks that run on pull requests in this repository:

• Every pull request: Skill Validation (lint.yml and validate.yml: skill structure, markdownlint, yamllint, actionlint, JSON syntax, ShellCheck, ruff, checkpoint schema; validate.yml runs ShellCheck at style severity), Eval Validation (eval-validate.yml) and Script Tests (script-tests.yml, every skills/github-release/scripts/tests/*.test.sh).
• Pull requests to main: security.yml with Betterleaks (secret scanning), zizmor (workflow static analysis), dependency review, Composer Audit and Opengrep SAST; Harness Verification (harness-verify.yml) and Template Drift (check-template-drift.yml). The organisation's security policy sets when dependency review and Opengrep fail: see dependencies and static analysis (SAST).
• Also on every pull request: Labeler (labeler.yml), the DCO sign-off check, SonarCloud Code Analysis and the CodeRabbit review status (GitHub Apps) and, for dependency-update pull requests, auto-merge (auto-merge-deps.yml). CodeQL for actions and python runs through GitHub's default setup.
