为什么值得关注

它将模型隐式推理转化为显式的、事件触发的步骤，通过精益的常驻规则和丰富的按需手册，使较弱模型能接近前沿水平，并通过可 grep 的标记验证合规性。

适合谁使用

使用 Claude Code 进行编码的开发者
将 AI 助手集成到软件开发流程中的团队
希望最大限度减少 AI 生成错误和令牌浪费的高级用户

典型使用场景

提高 AI 生成代码的质量并减少 bug
跨会话保持一致的规划和验证流程
通过结构化日志和检查点调试和跟踪 AI 推理过程

项目优势

核心仅约45行，配合按需文档，令牌开销低但覆盖全面
事件短语路由确保相关文档在需要时被读取，而非按主题标签
基于数字的阈值（如“10条消息”、“>50次命中”）实现机械性合规而非判断
每个禁止项都附带替代方案，防止规避行为

使用前须知

需要手动安装和针对每个项目配置
效果取决于模型遵循显式规则和标记的能力
对于简单任务可能引入不必要的开销

README 快速开始

Guardrails Kit v1.0

A portable CLAUDE.md + documentation set that makes Claude Opus / Sonnet operate as close to frontier (Fable) level as possible inside Claude Code: fewer logic errors, fewer introduced bugs, fewer wasted tokens. It works by converting the implicit judgment a stronger model applies automatically into explicit, checkable, event-triggered procedures a weaker model can execute mechanically.

What's in the kit

File	Role
`CLAUDE.md`	Always-loaded core: 12 iron rules, an event-phrased routing table, 4 hard stops. Deliberately small (~45 kit lines, hard cap 60) — always-on compliance is roughly constant-sum, so every extra line taxes obedience to all the others.
`docs/guardrails/PLAN.md`	Before starting non-trivial work: TASK block, premise check, prior-art search, baseline, decomposition, ask-vs-decide.
`docs/guardrails/CODE.md`	While editing: read-before-edit gates, twin/generated-file checks, and the REFERENCE SWEEP procedure (RS1-RS5).
`docs/guardrails/TRAPS.md`	Lookup tables for the classic reasoning traps: dates, epochs, mutation-vs-copy, async, floats/money, sort, division/modulo, regex, familiar-API lookalikes, closures, boolean logic. Read on demand via CODE.md C7.
`docs/guardrails/DEBUG.md`	When anything fails: reproduce-first loop, CAUSE line, failed-attempts ledger with the ESCALATION LADDER, red-flag table keyed on the model's own rationalization phrases.
`docs/guardrails/VERIFY.md`	Before claiming done/committing: 12-item echo protocol — every claim needs output quoted from a real tool result in the same turn.
`docs/guardrails/EFFICIENCY.md`	Token/context discipline as paired rules: every "read less" rule has a "read enough" floor.
`docs/guardrails/SESSION.md`	Long-session survival: docs/STATE.md template (S2), same-turn update triggers (S3), post-compaction recovery (S1), ANCHOR/DETOUR/DECISION ledger keywords.
`docs/guardrails/_FORMAT.md`	Authoring contracts for editing the kit itself (budgets, trigger phrasing, single-sourcing, sanctioned iron-rule pairs).
`MIGRATE.md`	The transport procedure for retrofitting a project that already has a CLAUDE.md — line-accounted, backup-first, verbatim-carry, user-checkpointed, idempotent, with an UPGRADE mode.

Not part of the installable kit (kit-source materials only): docs/research-digest.md (the 155-findin
