What it does

Change Impact is an agent skill from qshanx/docs-governance. 在改代码、数据、接口或治理文档前做有证据的影响分析，并在实施后把计划影响与实际 diff 对照；覆盖代码调用、数据/Schema、API 契约、测试、文档、ADR、部署、迁移和回滚。用于跨模块修改、高风险变更、数据库迁移、认证、公共接口、用户问“会影响哪里”“改之前检查一下”或实施后需要反思偏差时。English triggers: change impact analysis, blast radius, pre-change analysis, migration impact, rollback plan, post-implementation alignment.

Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Architecture decision records. The repository describes itself as: Claude Code、Codex 与 ChatGPT 的文档驱动开发治理插件：防文档腐烂、维护上下文与决策、契约协作、测试与回归证据。 The licence is MIT.

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

代码：入口、直接调用方、下游消费者、生成物和兼容层会受什么影响？
数据：Schema、迁移、历史数据、序列化、缓存和幂等键是否变化？
接口：API、消息、文件格式或 CLI 是否改变？消费者和提供者分别是谁？
测试：哪些成功标准、TEST-ID、契约测试和回归命令应证明变更正确？
文档：是否影响 MAP、ARCHITECTURE、STATUS、LOG、CONTEXT、ADR、CONTRACT、Spec/Plan、TESTS 或 REGRESSION？
发布：部署顺序、兼容窗口、数据恢复、回滚命令和不可逆部分是什么？

What it can do on your machine

Read from SKILL.md and the folder at commit 520696e. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Change Impact loads about 395 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 72 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~76
When it runs · the whole SKILL.md, loaded when a task matches: ~395

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

变更影响分析

默认只读。先用真实依赖与现有文档证明影响面，再实施；未知项明确标“未验证”。

修改前

依次回答：

代码：入口、直接调用方、下游消费者、生成物和兼容层会受什么影响？
数据：Schema、迁移、历史数据、序列化、缓存和幂等键是否变化？
接口：API、消息、文件格式或 CLI 是否改变？消费者和提供者分别是谁？
测试：哪些成功标准、TEST-ID、契约测试和回归命令应证明变更正确？
文档：是否影响 MAP、ARCHITECTURE、STATUS、LOG、CONTEXT、ADR、CONTRACT、Spec/Plan、TESTS 或 REGRESSION？
发布：部署顺序、兼容窗口、数据恢复、回滚命令和不可逆部分是什么？

证据优先取自真实 import/调用、路由、Schema、配置、生成脚本、git grep、git diff 和可执行测试。不要凭目录名猜依赖。

路由规则

架构、数据库、认证、部署拓扑或长期技术策略：检查 context-and-decisions / ADR。
跨端接口：先更新 contract-first 管理的唯一契约源，再规划消费者、提供者和联调证据。
需求、业务规则、风险或 Bug：让成功标准保留在 Spec/Issue，并用 test-collaboration 关联 TEST-ID。
Module 行为或下游依赖变化：实施后运行 module-regression；若权责、状态归属、Interface、依赖方向或核心流转改变，同步更新 ARCHITECTURE.md，并确保 MAP 仍能导航到它。
数据库迁移、破坏性接口、认证和生产发布：必须写回滚条件、恢复步骤、兼容期和不可逆部分；缺任何一项就标为阻塞，不代替人执行回滚。

输出

小改动在回复中给出：影响对象、证据、所需验证、文档同步和未知项。只有跨模块、高风险或用户明确要求留档时，才把报告写入 docs/impacts/；写文件前先确认，避免制造一次性文档。

实施后对照

完成实现后检查：

实际改动是否解决 Spec/Issue 中的原始问题。
实际 diff 是否超出已声明范围；超出项是否获得授权并补充影响分析。
测试和人工证据是否真正覆盖成功标准，而非只证明命令运行过。
CONTEXT、ADR、CONTRACT、TESTS、REGRESSION、MAP、ARCHITECTURE、STATUS 和 LOG 是否按实际变化同步。
是否遗留临时代码、兼容逻辑、迁移尾项或后续 Issue。

默认在交付回复中报告对照结论。只有高风险变更或用户要求正式评审时，才保存到 docs/reviews/。不要创建通用 REFLECTION.md。

Can I use Change Impact in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add qshanx/docs-governance --skill change-impact -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/change-impact, .gemini/skills/change-impact, .github/skills/change-impact and .opencode/skills/change-impact in your project.

What does Change Impact need to run?

Going by SKILL.md and its folder, Change Impact needs the command-line tools its instructions call (git).

Does Change Impact access the network?

SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Change Impact safe to install?

What licence does Change Impact use?

Change Impact is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Change Impact use?

About 395 tokens (SKILL.md is roughly 1.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
