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 | $0.00068 | $0.00576 |
| Opus 5 | $0.00034 | $0.00288 |
| Sonnet 5 | $0.00014 | $0.00115 |
| Haiku 4.5 | $0.00007 | $0.00058 |
Grade A, and why
bug-fixer 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 4d 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
缺陷修复技能 (bug-fixer)
Purpose
用可复现证据定位根因并恢复已经明确的预期行为。不要靠猜测修复，也不要把新的产品决策伪装成 Bug。
Trigger
- 报错、失败测试、审查意见或稳定复现步骤表明既有行为失效。
- 正确行为能由 Product Spec、公开接口、历史行为、测试或用户确认确定。
- 仅改变内部实现且不新增能力、不改变外部契约。
正确行为不清、证据互相矛盾或需要改变公开行为时，不触发本技能，转交 product-spec-builder。
Required context
- 预期行为及来源。
- 实际现象、复现步骤、日志或失败测试。
- 范围、非目标、完成证据和 R0/R1/R2。
- 相关代码、历史变更和当前验证入口。
缺少复现条件时，先形成最小诊断假设；无法验证任何假设则停止。
Workflow
- 复现问题，区分已证实事实、合理推断和未知项。
- 一次验证一个根因假设，找到最小充分证据链。
- 实施最小完整修复，不用大重构掩盖未知根因。
- 复跑原失败证据，并补充与风险相称的回归检查。
- 若范围或风险升级，更新维护契约并按 R2 规则交给 fresh reviewer。
Output
- 根因与证据。
- 修改文件和修复说明。
- 原问题验证、回归结果、失败或跳过项。
- 风险级别、残余风险和 reviewer 结论（如适用）。
Stop or escalate
- 正确行为需要用户或产品决策：升级为产品变更。
- 唯一方案会改变公开 API、数据、权限、业务流程或兼容性：升级为产品变更。
- 只能通过吞错、禁用检查或扩大范围隐藏问题：停止。
- 没有可复现或可替代验证证据：标记阻塞，不声明已修复。

What ships with it
2 files 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.

bug-fixer is a skill published in the GitHub repository arctan303/creator.skill (20 stars, last pushed 29d ago), licensed MIT. It adds 68 tokens to every session and 576 once invoked, about $0.0003 per session on Opus 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.
