event-review

event-review is a skill for Claude Code from reatcat/l123-harness. It costs 92 tokens per session (1,143 once invoked), scanned A, original, MIT.

A weekly review process for event logs and leftover task records, turning repeated problems or useful lessons into proposed memory, knowledge, or skill entries.

In plain words
What is it for?
Reviewing agent events, finding repeated failures or lost context, and placing possible improvements into an inbox for later sorting.
Why use it?
It helps recover useful patterns from past work without treating every logged event as a lasting rule.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

event-review 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 11d 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.

Event Review —— 事件提炼与记忆升级

你是一个干净 agent:不带任何正在进行的任务上下文,只做提炼。 方法论依据:hook 只记事件不做判断;由干净 agent 定期读事件、跨时间去重归类; 人每周批量审,分流到 CLAUDE.md / L2 索引 / memory / 丢掉。

输入

  • 事件日志:.agents/events/events-*.jsonl(按月,不可变)
  • 水位线:.agents/events/.last-reviewed(上次审到的行号/文件名)
  • 检查点:.agents/events/checkpoints/(compact 时抢救的任务状态)
  • 现有条目:CLAUDE.mdAGENTS.md.agents/INDEX.md.agents/knowledge/.agents/pitfalls/.agents/runbooks/ (用来去重:已经沉淀过的不要再提)

不要读 .agents/inbox/ 之外的待审内容当成结论引用;不要读 .agents/current/(那是活跃任务,与本次提炼无关,除非它在 checkpoints 里)。

步骤

1. 读事件,归类

从水位线之后开始读。关注的事件类型:

  • tool_error:同一类错误(同文件/同报错特征)出现 ≥2 次 → 候选 knowledge(坑)
  • compact + checkpoint_saved:对比 checkpoint 里的 plan/notes 与最终结果,找"被压缩掉但仍有价值"的结论
  • gate_block:反复被门禁拦截的同类修改 → 可能是流程问题
  • stop/session_start/session_end:用于判断任务边界,本身通常无价值

2. 写候选进 inbox(只写 inbox,不直接改任何受保护文件)

每个候选一个文件:.agents/inbox/YYYY-MM-DD-<slug>.md,头部包含:

类型: pitfall | knowledge | memory | skill-draft | discard
来源: 事件日志行 / checkpoint 路径
建议去向: CLAUDE.md 第X节 | .agents/INDEX.md 坑目录 | .agents/knowledge/xxx.md | memory(feedback) | 丢掉

3. 应用三个升级阈值

信号 阈值 产出
同类失败重复 ≥2 次 候选 knowledge(写 inbox)
用户重复说同样的话 第 2 次 memory(feedback 类型,写入项目 memory)
同一流程成功 3 次 skill 草稿提议(只提议,绝不自动安装
  • memory 写入:项目 memory(Claude Code 项目级 memory,feedback 类型;路径可用 /memory 查看)。memory 的写入不需要门禁(它是 agent 自己的笔记),但内容必须只关于"这个 agent 怎么干活"。
  • knowledge / pitfall / runbook / skill:一律先进 inbox,等用户审。

4. 陪同用户周审(逐条过)

对每个 inbox 条目,向用户说明:内容、来源证据、建议去向,请用户三选一:

  1. :按去向落盘 ——
    • CLAUDE.md / .agents/INDEX.md / .agents/gate.conf / skills / settings 会触发门禁:先征得用户同意,touch <项目根>/.claude/.gate-token,再写入(令牌一次性)。
    • 落盘后从 inbox 删除该条目,并在来源知识文件的"升级记录"打勾。
  2. :按用户意见修改后再落盘。
  3. :删除条目(大多数候选应该被丢掉,这是正常的)。

5. 收尾

  • 更新 .agents/events/.last-reviewed(记录已审到的事件文件与行号)。
  • 向用户汇报:收了 N 条 / 丢了 M 条 / 待跟进事项。

纪律

  • 跨时间去重优先于收录:同一个坑第二次出现时合并进已有条目,不新建。
  • 拿不准就标"存疑"留待下次,不要强行下结论。
  • 一次只审一周的量;事件太多时分批,不要一口气吞完撑爆上下文。

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.

event-review is a skill published in the GitHub repository reatcat/l123-harness (4 stars, last pushed 20d ago), licensed MIT. It adds 92 tokens to every session and 1,143 once invoked, about $0.0005 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 2026-08-31.
