Help author EasyApi rule files (.easyapi/ folder). Invoke when the user is editing an EasyApi rule file or asks to add/modify EasyApi rules (annotations, field rename, custom headers, etc.).
Guide how to write test cases in this project by first analyzing the target class to decide which test pattern, base class, and test utilities to use. Activate when user asks to write tests, add test coverage, or create test cases for any class.
Identifies and fixes bugs systematically. Invoke when user reports an error, test failure, or unexpected behavior that needs debugging and fixing.
Reviews a git commit to create a test plan document. Invoke when user asks to review a commit, analyze changes, or create test coverage plan for recent changes.

| description | Generates standardized Git commit messages following conventional commit rules. Invoke when user asks to write a commit message, create a commit, or needs help formatting a git commit. |
This skill generates clear, standardized Git commit messages that prioritize human readability and debugging efficiency.
Core Principle: The subject line answers "What is the user/system impact?" (Issue Y). The body explains "How did we implement it?" (Solution X).
Invoke this skill when:
Before writing the commit message, understand what changed:
# View staged changes
git diff --cached --stat
git diff --cached
# View recent commit history for style reference
git log --oneline -10
Identify the type of change from the mandatory type list (see Section 3).
Follow the Subject Line Rules (see Section 1).
Follow the Body Rules (see Section 2). When fixing a bug, the body MUST answer the four questions:
If a ticket/issue exists, append Fixes: #<issue> or Refs: #<issue> at the bottom.
Use a HEREDOC to preserve formatting:
git commit -m "$(cat <<'EOF'
<type>(<scope>): <subject>
<body>
Fixes: #<ticket>
EOF
)"
<type>(<scope>): <subject> or <type>!: <subject> for breaking changes, or release v?x.y.z for releasesAdd, Fix, Update, Remove). Never use past tense (e.g., Added, Fixed, Updated).fix: (bug fix), the subject MUST describe the problem (Y) (e.g., Fix login redirect loop on Safari). DO NOT put the implementation (X) in the subject.feat: (new feature), the subject MUST describe the feature itself (X) (e.g., Add dark mode toggle).You MUST prefix the subject with one of these exact types:
| Type | When to use | Auto-label |
|---|---|---|
| feat | A new feature for the user (X) | type: new feature |
| fix | A bug fix for the user (Y) | type: bug |
| enhance | Enhancement to existing features | type: enhancement |
| refactor | Code restructuring - no feature change and no bug fix | type: enhancement |
| perf | Performance improvement | type: enhancement |
| docs | Documentation changes only | type: doc |
| test | Adding or fixing tests | type: test |
| style | Code style (formatting, semicolons, etc.) - no logic change | type: chore |
| build | Build system changes (dependencies, build config) | type: chore |
| chore | Maintenance tasks (configs, tooling) | type: chore |
| amend | Small amendments or corrections | type: amend |
| release | Release version (format: release x.y.z) | release |
If a ticket/issue exists, MUST append one of these to the very bottom of the body:
Fixes: #<issue-number> (if it completely closes the issue)Refs: #<issue-number> (if it partially addresses it)Fix stuff, Update code, or WIP.Error was fixed → use Fix error).Updated → use Update).fix(payment): resolve checkout timeout during 3D Secure redirects
The checkout process was failing for users with banks requiring
3D Secure authentication due to a strict 5-second timeout.
Root cause: The API client did not account for external redirects,
which take 7-10 seconds to return to our callback URL.
Solution: Increased the global timeout to 30 seconds and added
exponential backoff retry logic specifically for the payment endpoint.
We also added a loading state to prevent duplicate submissions.
This change does not affect the regular non-3DS flow.
Fixes: #4421
When generating the commit, strictly follow this structural template:
<type>(<scope>): <Imperative summary of Y if fix, or X if feat>
<Problem summary>
Root cause: <Explanation>
Solution: <Implementation details X>
Impact: <Side effects>
Fixes: #<ticket>
If you want to enforce this automatically, install commitlint and use this commitlint.config.js:
module.exports = {
extends: ['@commitlint/config-conventional'],
rules: {
'subject-case': [2, 'always', 'sentence-case'],
'subject-max-length': [2, 'always', 50],
'body-max-line-length': [2, 'always', 72],
'type-enum': [2, 'always', [
'feat', 'fix', 'enhance', 'refactor', 'perf', 'docs', 'test',
'style', 'build', 'chore', 'amend', 'release'
]]
}
};
