What it does
Impact Trace is an agent skill from Prismer-AI/PrismerCloud. For a change point (function / type / endpoint / SQL column), enumerate its real blast radius across six dimensions with a grep citation per row, then derive the regression test scope. Every impact-table row must trace to a real search hit — never a self-asserted claim.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill.json`). Compatibility notes: ["claude-code","prismer-sdk"]
It sits in Databases, covering SQL and Citation management. It works with SQL and Prisma. The licence is MIT.
When your agent uses it
- Tasks that involve SQL
- Tasks that involve Citation management
Example prompts
- “/impact-trace”
Requirements
- Compatibility (from SKILL.md): ["claude-code","prismer-sdk"]
- Pre-approved tools (allowed-tools): Bash
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit e5d9444. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
rgnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, 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.
Compatibility
["claude-code","prismer-sdk"]
From compatibility in the SKILL.md frontmatter.
Context cost
Impact Trace loads about 1.5k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 416 words of instructions outside code blocks.
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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.

allowed-tools: Bash
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.

impact-trace
给定一个改动点（函数 / 类型 / endpoint / SQL 列），产出它的真实影响面（受影响的调用方 / 契约消费者 / 持久化写入 / 双 Prisma schema / daemon-SDK 镜像 / skill-role 引用）+ 由此推导的回归测试范围（apc/05 §2 S2 · apc/12 impact-trace 行）。
什么时候用：一个 bugfix / feature 改完，进 review 前需要知道"改这一处会波及哪些地方、要回归哪些层"；或评审要判断改动的 blast radius。
铁律：影响表的每一行都必须有 grep/search 证据（path+line）。凭记忆或推理写"这里应该会用到"是开卷考试——本 skill 的产出只认真实搜索命中。你自己不是 ground truth，rg 的命中集才是。
工具契约（签名以此为准，先核后用）
| 命令 | 作用 | 备注 |
|---|---|---|
rg <pattern> [path] -n | 主力搜索：直接调用方 / 契约消费者 / 引用点 | -n 出行号（证据必须带行号）；-l 只列文件；-t ts 限类型 |
rg -c <pattern> | 命中计数（核对"没漏"用） | 计数对不上就是漏搜 |
cloud code grep <pattern> --repo <abs> [--glob '*.ts'] | 白名单 repo 内搜索，输出 JSON [{path,line,snippet,sha256}] | 仅 PRISMER_WORKSPACE_ROOT 或 ~/.prismer/agents/<id>/scratch 内；出带 sha 的可引用片段。--glob 只支持 *.ext 形态 |
rg是本机主力；cloud code grep用于要产出可引用证据片段（带 sha256）时。两者的命中集应当一致——不一致就查是不是路径白名单/glob 把一部分挡在外面了。- 不要用单文件 grep 命中当全貌（memory
feedback_grep_full_range_for_seq_audit）。搜完要核计数：rg -c的总数 == 影响表行数（去掉 N/A 维度），对不上就是漏了。
六维影响面（逐维搜，缺一维要么有证据要么写 N/A 理由）
改动点波及面按六维穷举。任一维标 N/A 必须写理由；双 Prisma 维度永远不许静默省略（apc/12 负控：缺双 Prisma 维且无 N/A 理由 → 校验拒绝）。
| # | 维度 | 怎么搜（示例） | 找什么 |
|---|---|---|---|
| 1 | 直接调用方 | rg '\b<name>\b' -n -t ts | 谁 import / 调用了这个符号 |
| 2 | 契约消费者（API/wire） | rg '<endpoint-path>|<event-code>|<rpc-name>' -n | HTTP 路由消费者、SDK 类型、wire 帧的两端 |
| 3 | 持久化写入 | rg '<column>|<model>\.(create|update|upsert)' -n | 谁写这张表/这个字段 |
| 4 | 双 Prisma schema | rg '<field>' prisma/schema.prisma prisma/schema.mysql.prisma -n | SQLite + MySQL 两份 schema 是否都要改（不许省） |
| 5 | daemon-SDK 镜像 | rg '<name>' sdk/prismer-cloud/runtime/src -n | cloud 侧改了，daemon/SDK 侧有没有对称的一份要跟着改 |
| 6 | skill / role 引用 | rg '<name>' sdk/prismer-cloud/built-in-skills sdk/apc/skills -n | SKILL.md / role template / prompt 里有没有引用它 |
Procedure
1. 锚定改动点
明确改动点的精确标识（符号名 / endpoint 路径 / 列名）。一个改动可能有多个改动点——逐个搜，别只搜一个。
2. 逐维搜索，收集带行号的命中
# 维度 1：直接调用方（示例，把 <name> 换成真符号）
rg '\b<name>\b' -n -t ts > /tmp/impact-callers.txt
rg -c '\b<name>\b' -t ts # 核对命中计数
# 维度 4：双 Prisma（两份 schema 都要看）
rg '<field>' prisma/schema.prisma prisma/schema.mysql.prisma -n对每一维，把命中记成影响表的一行：{ path, line, dimension, contract, risk }。没有命中的维度：确认真的没有（不是搜错 pattern），然后写 N/A + 理由。
3. 组装影响表（副作用产出 1）
| path:line | 维度 | 契约 | 风险 | 回归 |
|---|---|---|---|---|
src/foo.ts:42 | 直接调用方 | 传参 shape | 改签名会破 | T0 |
每行必须能回指一条 rg/cloud code grep 命中。行数（不含 N/A 维）应等于去重后的真实命中数——自查：影响表行数 == Σ rg -c。
4. 推导回归测试范围（副作用产出 2）
按影响表命中的文件所在层映射到 tier（对齐 test-runner 选层规则）：
| 命中落在 | 回归 tier |
|---|---|
src/lib/** | T0 |
src/im/** / endpoint | T1 |
src/app/** | T2 |
| e2e / 跨端 | T3 |
daemon runtime/src/** | daemon 测试（runtime vitest） |
产出："本改动需回归 {tiers}，因为影响面落在 {层}"。

5.（可选）上报 criterion
若本 impact-trace 挂在一个 task 的 acceptance criterion 上，把结论上报：
cloud task verify-criterion "$PRISMER_TASK_ID" "<criterion-id>" --outcome passed \
--note "impact table: N rows, all grep-cited; regression scope: T0,T1"--outcome 合法值恰好四个：passed | failed | n/a | waived。
输出契约（机器判据按这个复验，别自由发挥格式）
本 skill 的验收判据不是「报告里出现了某些词」，而是把报告里的声明拿回文件系统复核（structured-criteria.ts 的 cited-evidence / dimension-coverage）。所以报告必须带下面三样可机器解析的东西——形状对但内容假的报告会被当场判红。
① 改动点声明（一行，锚点必须是本次真实改动点，且会被复核确实存在于该文件）：
CHANGE-POINT: <symbol> @ <path>② 影响表（markdown 表，首列是 path:line）：判据会逐行把 path:line 读回磁盘——文件不存在 / 行号越界 / 该行是空行，任意一条就判红；并且至少 3 条引用所在的那一行必须真的含改动点符号（"真实存在的行" ≠ "真实的搜索命中"），且这些命中要落在 ≥3 个不同文件里——把一条真命中抄满整张表是"单命中报告"，不是影响面（实证：一条真 path:line 复制 12 遍，加固前 5/5 全绿）。
| path:line | 维度 | 契约 | 风险 | 回归 |
| --- | --- | --- | --- | --- |
| src/foo.ts:42 | direct-callers | 传参 shape | 改签名会破 | T0 |③ 六维逐行作答（每维独占一行 + 固定 key）。判据找的是这一行，报告别处出现同一个词（比如正文里出现 npm run prisma:generate）不算答过——这正是旧判据 match:"prisma" 被证伪的地方：
- [1] direct-callers: <path:line>
- [2] contract-consumers: <path:line>
- [3] persistence-writers: <path:line> | N/A — <理由 ≥20 字符>
- [4] dual-prisma: <path:line> | N/A — <理由 ≥20 字符>
- [5] daemon-sdk-mirror: <path:line>
- [6] skill-role-references: <path:line> | N/A — <理由 ≥20 字符>N/A 必须带理由（去空白后 ≥20 字符）；只写 N/A 判红。行号照抄 rg -n 的真实输出，不许凭印象写。
每一维要有自己的证据：同一条 path:line 最多给 2 个维度当证据，第 3 个维度再引它就判红（N/A 维不受影响，它本来就没有引用）。
产出（副作用 oracle，报告里必须给）
- 影响表：每行
{path:line, 维度, 契约, 风险}+ 找到它的那条搜索。行的真实性 = grep 命中，不是叙述。 - 六维覆盖：六维全答；N/A 维带理由（双 Prisma 维不许静默省）。
- 回归范围：由影响表的层映射推出的 tier 集。
4.（若有 task）criterion 上报行：
cloud task verify-criterion落库 outcome，可回读 acceptance view 确认。
不许：把没有搜索命中的行写进影响表；漏搜一个真实调用方（rg -c 计数不核）；把双 Prisma 维度静默省掉；断言聊天文本而非 path:line 证据。
诚实边界
rg命中集是"文本匹配"的 ground truth，不是"语义调用图"——动态派发 / 字符串拼出来的引用 / 反射，文本搜不到。影响表覆盖的是可被文本搜索命中的引用面；无法静态搜到的动态引用要显式标注为已知盲区，不得声称"影响面已穷举"。- 回归范围是"应当回归哪些层"的推导，不代替真跑——真跑归 test-runner skill。
<!-- APC-ACK:v1 -->调用回执（APC 平台方运营纪律 · 自动注入，勿手改）
执行本 skill 的第一步，先落一条调用回执：
cloud skill ack impact-trace --task "$PRISMER_TASK_ID"按退出码分流（这条命令的退出码是承重信息，禁止用 || 兜底、; true、
set +e 或重定向把它抹掉）：
| exit | 含义 | 你要做的 |
|---|---|---|
0 | 回执已落库（im_task_logs.action='skill_ack'） | 继续执行本 skill |
3 | 无 task 上下文——本次运行没有 task，产不出回执 | 继续执行本 skill；但本次运行没有回执，任何报告里都不得声称已 ack |
4 | 你不是该 task 的 assignee，服务端拒绝 | 停下并上报：回执只能由执行该 task 的 agent 产生 |
1 | 其它失败（网络 / 服务端） | 重试一次；仍失败则继续执行，并在结果里显式标注「回执缺失」 |
回执只证明本 skill 被调度，不证明执行正确——效果证明由本 skill 自己的 acceptanceCriteria 副作用断言承担（apc/04 §2 层 1 诚实标注）。

What does Impact Trace need to run?
Going by SKILL.md and its folder, Impact Trace needs the command-line tools its instructions call (rg and npm). Its frontmatter pre-approves these tools: Bash. Compatibility (from SKILL.md): ["claude-code","prismer-sdk"].
Does Impact Trace access the network?
SKILL.md contains no URLs. Its commands use npm, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Impact Trace safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Impact Trace use?
Impact Trace is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Impact Trace use?
About 1.5k tokens (SKILL.md is roughly 6.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
