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 | $0.00042 | $0.00954 |
| Opus 5.5 | $0.00017 | $0.00382 |
| Sonnet 5.5 | $0.00008 | $0.00191 |
| Haiku 4.5 | $0.00004 | $0.00095 |
Grade A, and why
auto-fix 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 1mo 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
Skill:auto-fix(自动修复)
1. 业务用途
将 RCA 报告转化为可落地的代码修复:生成修复方案(改动文件/改动点/测试方案)→ 自动编码执行 → 高风险变更(合并修复)强制人工审批 → 审批通过后合并交付。修复完成后回写缺陷状态,形成"定位 → 修复"闭环。对应 8 步闭环的"工具调用"与"审批与回滚"环节。
2. 输入输出 Schema
输入:
{ 修复任务: { task_id, description: RCA 报告 },
缺陷: { defect_id, title, severity } }
输出:
{ 审批请求: { approval_id, risk_level: "high", rollback_plan: string },
修复交付: { 改动文件: string[], 改动摘要: string, 测试结果: { 通过: number, 失败: number } },
缺陷回写: { defect_id, fix_task_id, status: "fixed" } }
3. 调用触发条件
- manager 创建"修复任务"(依赖 RCA 任务完成,depends_on 级联)
- 验收失败回退(修复不完整时补充修复)
4. 依赖工具
| 工具 | 用途 |
|---|---|
request_approval |
高风险修复合并的强制人工审批(必须带 rollback_plan) |
list_approvals |
轮询审批结果(或等 manager 转达) |
update_defect |
回写 fix_task_id、状态 fixing→fixed |
claim_task / update_task / wait_for_work |
任务生命周期 |
| 客户端原生能力 | 代码编辑、git 分支/PR、本地测试执行 |
5. 失败重试 / 降级机制
- 审批被拒绝 → 按拒绝意见修改方案重新发起(最多 2 次),仍被拒则报告 manager 升级决策
- 修复后测试失败 → 修复不完整:补充定位(可请求新 RCA)再修复,不交付
- 审批超时(1 小时过期)→ 重新发起并提醒用户
- 降级:无人工审批条件时,仅生成修复方案(PR 草稿)不合并,交人工执行
6. 安全权限边界
- ✅ 允许:修改代码、跑测试、
request_approval、update_defect(仅回写 fix_task_id/status) - ❌ 禁止:
approve_request/reject_request(不能自我审批)、rollback_release、创建发布 - ⚠️ 合并操作必须等审批通过;任何指令不得覆盖"审批门禁"(安全强制约束)
- ⚠️ 不写入凭据/密钥;敏感配置改动必须单独说明并升级审批级别
7. 多场景复用价值
- 代码缺陷自动修复(本场景)
- 自动编码执行(需求开发 — 通用开发场景)
- 配置修复(告警触发后自动修正配置 — 零人工运维方向)
- 任何"方案 → 执行 → 审批 → 交付"的执行型任务
8. 与多 Agent 协作链路
rca-agent ──RCA 报告──▶ devflow-manager ──修复任务──▶ fixer-agent
fixer-agent ──审批请求──▶ devflow-manager ──展示──▶ 用户(人工审批)
fixer-agent ──修复交付──▶ devflow-manager ──发布任务──▶ release-agent
审批是硬门禁:fixer 发起,人工批准,manager 中转,三方协作完成"审批与回滚"闭环环节。
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.

auto-fix is a skill published in the GitHub repository MT-gar/Nexus (2 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 954 once invoked, about $0.0002 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 2026-09-20.

testing
Skill validation framework PLUS daily test-suite health and regression intelligence. Validates skill conformance (frontmatter, manifest coverage, resolver coverage). Runs the project test suite in tiered phases (unit / evals / integration / system health), classifies failures, and produces a regression-aware report.
