git-commit

A guide for writing conventional commit messages for Java projects. Conventional commits use a standard type and scope, such as fix(plugin-loader), to describe a change clearly.

In plain words
What is it for?
Use it after Java code changes or before a pull request to write feature, fix, refactor, test, documentation, performance, build, or maintenance commit messages.
Why use it?
It makes Java repository history easier to scan and keeps commit subjects, bodies, issue references, and wording consistent.

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

git-commit 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 yesterday.

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.

Git Commit Message Skill

Generate conventional, informative commit messages for Java projects.

When to Use

  • After making code changes
  • User says "commit this" / "commit changes" / "create commit"
  • Before creating PRs

Format Standard

Use Conventional Commits format:

<type>(<scope>): <subject>

<body>

<footer>

Types (Java context)

  • feat: New feature (new API, new functionality)
  • fix: Bug fix
  • refactor: Code refactoring (no functional change)
  • test: Add/update tests
  • docs: Documentation only
  • perf: Performance improvement
  • build: Maven/Gradle changes
  • chore: Maintenance (dependency updates, etc)

Scope Examples (Java specific)

  • Module name: core, api, plugin-loader
  • Component: PluginManager, ExtensionFactory
  • Area: lifecycle, dependencies, security

Subject Rules

  • Imperative mood: "Add support" not "Added support"
  • No period at end
  • Max 50 chars
  • Lowercase after type

Body (optional but recommended)

  • Explain WHAT and WHY, not HOW
  • Wrap at 72 chars
  • Reference issues: "Fixes #123" / "Relates to #456"

Examples

Simple fix

fix(plugin-loader): prevent NPE when plugin directory is missing

Check for null before accessing plugin directory to avoid
NullPointerException during initialization.

Fixes #234

Feature with breaking change

feat(api): add support for plugin dependencies versioning

BREAKING CHANGE: PluginDescriptor now requires semantic versioning
format (x.y.z) instead of free-form version strings.

Closes #567

Refactoring

refactor(core): extract plugin validation logic

Move validation logic from PluginManager to separate
PluginValidator class for better testability and separation
of concerns.

Test addition

test(plugin-loader): add integration tests for plugin loading

Add comprehensive integration tests covering:
- Loading from directory
- Loading from JAR
- Error handling for invalid plugins

Build/dependency update

build(deps): upgrade Spring Boot to 3.2.1

Update Spring Boot from 3.1.0 to 3.2.1 for security patches
and performance improvements.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

git-commit is a skill published in the GitHub repository decebals/claude-code-java (722 stars, last pushed 3d ago), licensed MIT. It adds 38 tokens to every session and 1,330 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
