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 | $0.00029 | $0.00609 |
| Opus 5.5 | $0.00012 | $0.00244 |
| Sonnet 5.5 | $0.00006 | $0.00122 |
| Haiku 4.5 | $0.00003 | $0.00061 |
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 7d 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。
- 提出有证据的有限根因假设，优先验证最能区分原因的检查；独立调查可并行，避免重复写入和无界尝试，收敛到最小充分证据链。
- 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。
- 范围改变时更新相关契约，按具体影响重新评级；只有 R2 才自动要求 fresh reviewer，路线升级不自动等于 R2。
- 修复后同步受影响现状、命令与任务状态，不引用已失效的历史决定。
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 (19 stars, last pushed 7d ago), licensed MIT. It adds 29 tokens to every session and 609 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.

sentry-fix-issues
Find and fix issues from Sentry using MCP. Use when asked to fix Sentry errors, debug production issues, investigate exceptions, or resolve bugs reported in Sentry. Methodically analyzes stack traces, breadcrumbs, traces, and context to identify root causes.
debugging-executions
Debug failed or wrong-output workflow executions using executions tools. Load when the user reports execution failures, unexpected node output, empty parameter values after a successful run, or a node showing a red or failed expression error. Also load when a live run you started for the user fails with an error from…
audit
Run technical quality checks across accessibility, performance, theming, responsive design, and anti-patterns. Generates a scored report with P0-P3 severity ratings and actionable plan. Use when the user wants an accessibility check, performance audit, or technical quality review.
n8n-docs-assistant
Answers n8n product, setup, credential, node, hosting, API, and usage questions from current n8n docs. Use when the user asks how to configure, set up, troubleshoot, or understand n8n behavior, especially credential setup questions — including which OAuth scopes or permissions a provider app needs.

Upgrade the Sentry JavaScript SDK across major versions. Use when asked to upgrade Sentry, migrate to a newer version, fix deprecated Sentry APIs, or resolve breaking changes after a Sentry version bump.
dorodango
Polishes working code through successive quality passes in fresh subagents. Use after tests pass when code needs multi-dimension refinement before release.
