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 | $0.00037 | $0.00452 |
| Opus 5.5 | $0.00015 | $0.00181 |
| Sonnet 5.5 | $0.00007 | $0.00090 |
| Haiku 4.5 | $0.00004 | $0.00045 |
Grade A, and why
refactoring-patterns 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
重构模式（Refactoring Patterns）
目标
在不破坏现有行为的前提下，逐步提升可读性、可测试性与可维护性。
适用场景
- 巨型函数、深层嵌套、重复逻辑。
- 历史模块耦合严重，改一处影响多处。
- 需要在持续交付中逐步替换旧实现，而非一次性重写。
执行顺序（强制）
- 先锁定行为：补齐回归测试或特征测试（characterization tests）。
- 小步提交：每次只做一种重构动作（如提取函数、重命名、移动模块）。
- 每步验证：确保测试通过后再进入下一步。
- 接口稳定优先：对外 API 先兼容，内部再逐层替换。
常用模式
- 提取函数（Extract Function）：把多职责逻辑拆成具名步骤。
- 引入门面（Facade）：先封装旧接口，再在门面后逐步替换实现。
- 依赖倒置（Dependency Inversion）：把硬编码依赖替换为可注入接口。
- 删除死代码（Dead Code Removal）：仅在有覆盖和调用链确认后执行。
禁止事项
- 无测试直接大规模重写。
- 同一提交混入功能变更与重构变更。
- 修改外部契约却不提供迁移路径或兼容层。
完成标准
- 行为保持一致（回归测试通过）。
- 复杂度下降（函数长度、嵌套层级、重复率可观测改善）。
- 变更说明清晰（记录重构动机、范围与风险点）。
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.

refactoring-patterns is a skill published in the GitHub repository MisonL/Ling (8 stars, last pushed 7mo ago), licensed MIT. It adds 37 tokens to every session and 452 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 2026-08-31.
Other skills, from other repositories
autoreview
Structured code review through the shared OpenClaw agent-skills installation.
omh-code-review
This is an OMH code-review workflow skill, projected for Agent Skills hosts (Claude Code, Codex, Cursor, opencode, OpenClaw, pi).
revdiff-plan
Review the last Codex assistant message (plan, analysis, or proposal) with inline annotations in a TUI overlay. Extracts the most recent response from Codex rollout files and opens it in revdiff for review and annotation. Activates on "revdiff-plan", "review plan with revdiff", "annotate plan", "review last response"…
explore-unknowns
Guide the user through a quadrant walk that maps the unknowns of a task — open by listing the known knowns, then work through known unknowns, unknown knowns, and unknown unknowns one stage at a time, ending with a complete four-quadrant map in the user's hands. Use when a request is ambiguous or underspecified, the…
re0-merge
Review and land an external contribution the way this suite does: gate it against the thesis, land it with the author's credit intact, complete a new skill rather than merging it raw, then approve, credit, and explain before closing. Use when reviewing a pull request, as any collaborator or maintainer, not only the…
asplos-writing-style
Use when drafting or revising ASPLOS prose — engineering the first two pages that rapid review actually reads, stating the cross-layer insight as one quotable sentence, structuring per-layer mechanism sections, writing bounded claims, and fitting everything into 11 self-contained pages that include figures and…
