development-retrospective

development-retrospective is a skill for Claude Code, Codex from Peiiii/nextclaw. It costs 57 tokens per session (782 once invoked), scanned A, original, MIT.

A lightweight end-of-task review that checks whether the work produced a reusable lesson for future development. It records an improvement only when the evidence supports a lasting change.

In plain words
What is it for?
Use it to check goals, ownership, boundaries, rework, wrong decisions, and wasted investigation. It helps decide whether to fix the current task, improve an existing process, or record no lasting change.
Why use it?
It prevents teams from turning every mistake into a new rule, test, or document. It also helps identify unfinished work and recurring process problems.

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

development-retrospective 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 6d 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

Development Retrospective

目标

回答“这次工作是否产生了能让以后做得更好的经验”。每个开发任务结束前做一次轻量判断;没有信息增量时直接结束,不制造规则、测试和文档噪声。

轻量复盘

检查:

  • 最初目标和成功条件是否准确;
  • producer、owner、boundary、consumer 判断是否正确;
  • 方案和实际交付是否一致;
  • 是否发生返工、误判、无效调查、重复验证或错误路由;
  • 下次能否用更短路径取得同等可信度;
  • 当前任务是否其实尚未完成。

当前任务未完成时返回对应返工阶段,不用“后续优化”掩盖缺口。

正式沉淀门槛

同时判断:

  1. 这是重复问题、系统性缺口或高影响单次事件吗?
  2. 现有 owner 本应阻止它却没有阻止吗?
  3. 改进能覆盖一类问题,而不只是当前文件或一句反馈吗?
  4. 新机制的触发成本和误报是否低于问题损失?

任一答案不足时修正当前任务即可,明确“不新增规则”。

根因层次

  • 表层症状:用户或系统看到了什么;
  • 直接触发:哪一步判断或执行出错;
  • 结构根因:owner、路由、合同或验证为何允许它发生;
  • 机制缺口:现有规则是缺失、重复、过宽、触发不到还是不可执行。

正式沉淀时读取经验抽象层级校准,把实例提升到最高但仍可执行的层级,避免窄规则和空泛口号。

持久化路由

  • 用户明确要求改进 AI 驱动开发体系,或反馈命中重复、系统性、高影响机制缺口:由 nextclaw-agent-instructions-governance 进入体系演进判断;
  • 产品想法、设计、计划、PRD、路线图和普通项目知识:project-knowledge-governance
  • 重要交付、跨模块长链路、重大根因、红区或大型治理批次:nextclaw-iteration-log-governance
  • 已确定需要修改 AGENTS、commands、skill、reference 或治理脚本:nextclaw-agent-instructions-governance
  • 稳定行为回归风险:优先自动化测试;
  • 高信号、低误报、可确定执行的问题:扩展已有通用 script;
  • 没有复用价值的一次性经验:不落盘。

规则更新优先删除、合并、收窄或修正现有 owner;只有不存在稳定 owner 时才新增 skill。能由测试或 script 确定解决的问题,不重复追加自然语言。

输出

说明是否需要沉淀;命中时说明重复模式、证据、现有 owner 为什么失效、选择的单一落点和验证方式;未命中时明确不落盘。

本阶段不默认继续修改实现,不把每次任务摘要写进 docs/logs,也不把用户可见 release notes 当作内部复盘。

Files

What ships with it

1 file 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.

Changes

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.

development-retrospective is a skill published in the GitHub repository Peiiii/nextclaw (254 stars, last pushed yesterday), licensed MIT. It adds 57 tokens to every session and 782 once invoked, about $0.0003 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 2026-08-30.
