About this skill
End agent responses that include code changes with a Change summary table (Code / Tests / Config / Docs) and per-file line counts from git diff, and the commit message conventions for this app. Use after any code change and before creating a commit.
What this skill tells your AI
The instructions your AI receives, as published by builderio/agent-native in templates/tasks/.agents/skills/change-summary/SKILL.md and read by ahel’s review.
When you modify this repo, end every response that includes code changes with a Change summary section.
Required format
Split the summary into four buckets. Omit a bucket only when nothing changed in it.
## Change summary
### Code
| File | + | − |
|------|---|---|
| `path/to/file.ts` | 12 | 3 |
**Subtotal:** +N −M across K files
### Tests
| File | + | − |
|------|---|---|
| `path/to/file.test.ts` | 4 | 1 |
**Subtotal:** +N −M across K files
### Config
| File | + | − |
|------|---|---|
| `server/plugins/db.ts` | 1 | 1 |
**Subtotal:** +N −M across K files
### Docs
| File | + | − |
|------|---|---|
| `AGENTS.md` | 2 | 2 |
**Subtotal:** +N −M across K files
**Total:** +N −M across K files
How to classify files
| Bucket | Include |
|---|---|
| Code | actions/*.ts (non-test), app/**, server/** except test-only helpers |
| Tests | **/*.test.ts, **/test-*.ts, in-memory test DB SQL in server/db/test-tasks-table.ts |
| Config | DB migrations and table defs (server/plugins/db.ts, server/db/schema.ts), package.json, tsconfig*.json, vite.config.*, CI/workflow YAML, env templates |
| Docs | *.md, skill files under .agents/skills/ and .claude/skills/ |
New untracked files: list under the right bucket with +lines 0 (all lines are additions).
Renames/deletes: show the old path with deletions and the new path with additions, or one row with net +/−.
How to compute counts
Prefer git over guessing:
git diff --numstat
git status --short # for untracked files
wc -l <new-file> # line count for new files
Use line counts from git diff --numstat (added, removed). Do not approximate from memory.
When to include it
- Always after implementation, refactor, or fix commits in the working tree.
- Skip only for pure Q&A with no file edits.
- If the user asked only for a review with no changes, skip the summary.
Place the change summary before the final 🟢/🟡/🔴 status line.
Commit Message Conventions
- Never include
Made-with: Cursorin commit messages. Remove it if it appears in a generated message. - Use one of these prefixes:
feature: ...orfeature(PROJECT): ...fix: ...orfix(PROJECT): ...refactor: ...orrefactor(PROJECT): ...technical: ...ortechnical(PROJECT): ...chore: ...orchore(PROJECT): ...
PROJECTis optional. If provided, it must be one ofgeneratororweb.- Before creating any commit, always:
- ask for confirmation,
- show the proposed commit message first,
- commit only after explicit user approval.
