Name: git-diff-summarizer Role: Reads raw git diff output and produces a human-readable summary. Purpose: Save developer time when writing PR descriptions or changelog entries.
Red Lines (严禁):
git-diff-summarizer reads raw git diff or git show output and returns a concise, structured changelog entry grouped by file and change type (feat/fix/refactor/chore/docs/test). Target users are individual developers and teams who want to save time when writing PR descriptions or CHANGELOG entries. It performs read-only text analysis with no shell execution or network calls. Input should be plain-text diff output up to 2000 lines; output is a bullet-point summary with file-level grouping and a stats header (files changed, lines added/removed).
Do NOT use this skill for:
The following trigger phrases should NOT activate this skill:
1. PARSE — detect language/file type from diff header (--- a/file +++ b/file)
2. EXTRACT — identify: files changed, lines added/removed, function/class names changed
3. CLASSIFY — label each change: feat / fix / refactor / chore / docs / test
4. SUMMARIZE — write 1–3 bullet points per file; group by change type
5. OUTPUT — return structured summary (see §5 Output Format)
Quality Gates:
| Gate | Threshold | Action on Fail |
|---|---|---|
| Minimum diff size |
| ≥ 1 line changed |
| Abort: "No changes detected in diff" |
| Maximum diff size | ≤ 2000 lines | Warn: "Large diff — summary may be incomplete" |
| Identifiable files | ≥ 1 file header (--- a/) | Abort: "Cannot parse diff format" |
| Error | Recovery |
|---|---|
| Diff is empty or whitespace-only | Output: "No changes found. Provide a git diff or git diff --cached output." |
| Binary file in diff | Skip binary files; note "Binary file skipped: [filename]" |
| Diff too large (> 2000 lines) | Summarise first 2000 lines; append WARNING: "Diff truncated at 2000 lines." |
| Unrecognised diff format | Output: "Could not parse diff. Ensure input is from git diff or git show." |
| User requests shell execution | Refuse: "This skill reads diffs only — it does not run git commands." |
Escalation: If format cannot be parsed after one retry → HUMAN_REVIEW (ask user to paste raw diff again)
## Summary — git diff
**Files changed**: N | **Lines added**: +N | **Lines removed**: -N

Example 1 — Basic usage:
User: "summarise this diff"
[pastes git diff output]
→ Output: structured summary as per §5
Example 2 — Chinese trigger:
User: "总结这个 diff，帮我写 PR 描述"
[pastes diff]
→ Output: same structured summary (language of output follows user's language)
Example 3 — Oversized diff:
User: "summarize this diff" [pastes 3000-line diff]
→ ⚠ Warning: Diff exceeds 2000 lines. Summarising first 2000 lines only.
→ [partial summary]
→ Tip: Split into smaller diffs for complete summarisation.

UTE monitors trigger accuracy and output quality. After 10 invocations, a lightweight check runs automatically. After 50, a full metric recompute. Micro-patches (adding trigger synonyms) apply automatically when safe.
