What does this agent skill do?

Skill: impact-check

WHAT

Purpose và context

  • Purpose: Before modifying any symbol (function, class, variable, config key), map all dependents so no callers blindsided.
  • Trigger (when to use):
    • Before editing shared utility, base class, or widely-imported module
    • Before renaming or deleting anything
    • As first step of safe-change or propose
  • Non-goals: không sửa code (output only); không tạo trang wiki cho symbol chưa document (chỉ ghi gap).

Mental model

symbol → mọi reference (import · call · đọc output) → Direct / Indirect → test refs tách riêng → báo cáo + wiki gap.

Input và output contract

FieldRequired?Ý nghĩa
Insymbol(s) cần đổicófunction, class, variable, config key
Outdanh sách referencecófile path, line number, cách dùng, nhãn Direct/Indirect; zero ngoài file thì nói rõ
Outtest refscó nếu cóliệt kê riêng
Outwiki gapnếu cósymbol chưa có trong wiki/
Outdraft output reportcó (trừ khi 0 artefact)llmwiki/wiki/sources/draft/DDMMYY-<ten>.md

Rules và capabilities

  • RULE-01 (MUST): Do not modify anything during this skill — output only.
  • RULE-02 (MUST): If codebase large, search by symbol name AND file pattern (e.g. all *.ts files).
  • RULE-03 (MUST): Do not assume symbol unused because no direct callers — check indirect dependents too.
  • Capabilities: đọc/tìm toàn codebase (text search hoặc code graph); ghi draft report + index/log wiki.

Failure boundaries

  • Symbol mơ hồ (nhiều định nghĩa cùng tên) → clarify symbol chính xác.
  • Zero reference ngoài file → succeeded, nói rõ "0 reference ngoài file".
  • Không tìm được hết (codebase quá lớn, search lỗi) → partial, ghi phạm vi đã quét.

Chi tiết từng bước (nguồn chân lý cho W01–W07):

  1. Identify exact symbol(s) to change.
  2. Search entire codebase for all imports, calls, references to each symbol.
  3. For each reference: note file path, line number, how it uses symbol.
  4. Classify each reference:
    • Direct — calls or imports symbol itself
    • Indirect — depends on behaviour symbol produces (e.g. reads its output)
  5. Report full list. If zero references found outside file, state explicitly.
  6. Flag any reference in test file separately — those must update or give false confidence.
  7. If symbol not yet documented in wiki/, note as gap — do not create entry now. Wiki entries only written after code committed (see verify-before-commit).

Validation và stopping

Dừng khi mọi hit đã có path + line + nhãn Direct/Indirect. Không kết luận "unused" chỉ vì thiếu direct caller (RULE-03). Không file code nào bị sửa.

Examples

  • Positive: đổi chữ ký formatDate(d) trong src/utils/date.ts → 12 Direct (import) + 2 Indirect (đọc chuỗi output để parse) + 3 test refs liệt kê riêng → báo cáo + draft DDMMYY-impact-format-date.md.
  • Boundary/failure: config key retry_limit không có caller trực tiếp nhưng được đọc qua config[key] động → xếp Indirect, KHÔNG báo "unused"; nếu quét không hết thì báo partial kèm phạm vi.

Delivery — Output Report

After all main skill tasks complete, write a propose draft to the wiki.

Steps

1. Build the filename:

  • Format: DDMMYY-<ten>.md
  • DDMMYY = today (e.g., 020626 for 2 June 2026)
  • <ten> = 2–4 kebab-case words summarising what was done (e.g., landing-page-coteccons, brand-kit-fintech, ingest-auth-spec)

2. Write llmwiki/wiki/sources/draft/DDMMYY-<ten>.md:

---
type: draft
title: "DDMMYY-<ten>"
status: proposed
tags: [<skill-name>, output-report]
timestamp: YYYY-MM-DD
---

# DDMMYY-<ten>
**Type:** draft
**Status:** proposed
**Tags:** <skill-name>, output-report
**Proposed:** YYYY-MM-DD

## What
<One sentence — what this skill invocation produced or decided>

## Output
<Key artefacts, files created/modified, or decisions made>

## Files
| File | Action |
|------|--------|
| `path/to/file` | created / modified |

## Notes
- Invoked via: `/<skill-name>` skill

## Origin
- **Draft:** `wiki/sources/draft/DDMMYY-<ten>.md`
- **Commit:** _(filled by verify-before-commit)_
- **Date promoted:** _(filled by verify-before-commit)_

3. Update wiki index & log:

  • llmwiki/wiki/index.md — append one row: | [DDMMYY-<ten>](sources/draft/DDMMYY-<ten>.md) | draft | YYYY-MM-DD |
  • llmwiki/wiki/log.md — append: ## YYYY-MM-DD — <skill-name> — <ten>

Skip only when the skill produces zero artefacts and zero decisions (e.g., a pure display mode like /caveman-stats).

Add the canonical catalog link to the repository README so users can inspect current installs and available audits. The publishing guide covers the complete discovery path.
