l2-capture

l2-capture is a skill for Claude Code, Codex from cloud99277/KitClaw. It costs 87 tokens per session (1,042 once invoked), scanned A, original, MIT.

A small tool for saving one to three concise decisions, actions, or lessons from a conversation into shared team memory. L2, or Whiteboard memory, means short-lived shared notes rather than full documentation.

In plain words
What is it for?
Use it to record a team decision, capture a follow-up task, or preserve a useful learning in the shared memory system.
Why use it?
It reduces repeated decisions and keeps important follow-up work visible without turning every conversation into a long document. It also checks entries for duplicates and quality.

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

l2-capture 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/l2_capture.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

l2-capture

为共享 L2 Whiteboard 提供一个薄封装写入入口。

它做四件事:

  1. 接收原始文本或已经标注好的候选条目
  2. 规范成 decision / action / learning
  3. 先做去重和质量检查
  4. 串行调用 memory-manager 完成最终写入

不要用它写 L3 文档;稳定文档仍然进入 Obsidian 知识库。

什么时候用

  • 用户明确说“记到 L2 / 写入白板 / 记下这个决策 / 记下这个待办”
  • 要从当前任务或对话中提炼 1-3 条共享记忆
  • 需要避免直接调用 memory-update.py 时的并发与重复问题

快速开始

先 dry-run 看候选条目:

python3 ~/.ai-skills/l2-capture/scripts/l2_capture.py \
  --project agent-toolchain \
  --from-text "[decision] 共享稳定知识统一落到 20_Knowledge_Base"

第二版也支持从原始总结里自动提炼:

python3 ~/.ai-skills/l2-capture/scripts/l2_capture.py \
  --project agent-toolchain \
  --from-text "我们决定把共享稳定知识统一放到 20_Knowledge_Base。后续需要单独评估 Git 化方案。实测下来 L3 更适合目录监听自动入库。"

确认后写入:

python3 ~/.ai-skills/l2-capture/scripts/l2_capture.py \
  --project agent-toolchain \
  --from-text "[decision] 共享稳定知识统一落到 20_Knowledge_Base" \
  --apply

支持多条:

python3 ~/.ai-skills/l2-capture/scripts/l2_capture.py \
  --project agent-toolchain \
  --from-text "
[decision] OpenClaw 私有记忆不覆盖共享事实
[action] 单独评估 20_Knowledge_Base 的 Git 化方案
[learning] L3 适合目录监听自动入库
" \
  --apply

如果原始文本只对应一条,给定类型即可:

python3 ~/.ai-skills/l2-capture/scripts/l2_capture.py \
  --project agent-toolchain \
  --type learning \
  --from-text "L3 适合目录监听自动入库;L2 更适合结构化短条目写入。" \
  --apply

输入规则

  • 优先使用显式标记:
    • [decision] ...
    • [action] ...
    • [learning] ...
  • 也支持:
    • decision: ...
    • action: ...
    • learning: ...
  • 如果只有一条内容,可以配合 --type
  • 如果没有显式标记,也会尝试自动提炼 1-3 条候选

自动提炼规则

  • 优先从一句话里识别 decision / action / learning
  • 会按关键词和句首信号做启发式分类
  • 返回 source_mode=auto 和命中的 signals
  • 如果内容太泛、太长,仍然会被过滤或要求你显式标注

默认行为

  • 默认是 dry-run
  • 只有加 --apply 才真正写入 ~/.ai-memory/whiteboard.json
  • 写入前会读取现有 whiteboard 做重复检查
  • 真正落盘时会串行写入,避免多条并发写 whiteboard 失败

和 memory-manager 的分工

  • memory-manager:底层读写与检索统一入口
  • l2-capture:更方便的 L2 写入入口

需要了解 L2 规则时,读取:

  • ~/.ai-skills/memory-manager/references/whiteboard-template.md
Files

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.

l2-capture is a skill published in the GitHub repository cloud99277/KitClaw (5 stars, last pushed 6mo ago), licensed MIT. It adds 87 tokens to every session and 1,042 once invoked, about $0.0003 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.
