Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00030 | $0.00531 |
| Opus 5.5 | $0.00012 | $0.00212 |
| Sonnet 5.5 | $0.00006 | $0.00106 |
| Haiku 4.5 | $0.00003 | $0.00053 |
Grade A, and why
api-contract-governance scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
API 契约治理技能
使用场景
-
新增或改造后端 REST 接口。
-
前端接入或修改 API 消费。
-
修复响应体、分页、错误码或登录态接口验证失败。
-
对齐 Controller、前端 API 类型和页面消费字段。
输入
-
待治理接口路径、Controller、前端 API 文件或接口失败列表。
-
当前统一响应体、分页、错误码和登录态验证要求。
输出
-
API 契约一致的后端和前端改动。
-
更新后的接口说明或验证记录。
-
后端编译、单测、前端类型检查或 HTTP 验证结果。
执行步骤
-
读取
rules/api-contract.md、rules/testing-and-validation.md。 -
扫描 Controller 是否存在手动
ApiResponse、对外R<T>、AjaxResult、TableDataInfo、旧分页参数。 -
扫描前端是否读取
msg/rows/records/list、判断code === 200或使用旧字段 fallback。 -
后端按业务对象、
ListResult<T>、PageResult<T>、IdResponse、Void修复。 -
前端按 request 解包后的业务数据和标准分页字段修复。
-
涉及运行态验证时，使用本地临时登录态执行真实 HTTP 请求，不把账号、密码、token、cookie 写入仓库。
-
按影响范围执行 Maven、npm 或 pnpm 验证；失败先修复再继续。
依赖 rules
-
rules/api-contract.md -
rules/testing-and-validation.md -
rules/coding-conventions.md
禁止行为
-
禁止保留旧字段兼容层。
-
禁止将
code === 200作为成功判断。 -
禁止用
items ?? list或同类 fallback 掩盖后端问题。 -
禁止把账号、密码、token、cookie 写入仓库。
-
禁止把 Feign
R<T>暴露给前端 REST。
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 2mo ago First seen · 49 lines · 30 tokens per session scan A 5c4a7fdbe38f
api-contract-governance is a skill published in the GitHub repository SourceLin/sourcelin-cloud-blog (11 stars, last pushed 4mo ago), licensed MIT. It adds 30 tokens to every session and 531 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
