task-retrospective

task-retrospective is a skill for Codex from BuildrAI/Buildr. It costs 86 tokens per session (2,942 once invoked), scanned A, original, MIT.

A process for reviewing completed or abandoned Buildr tasks. Buildr is a task-execution system that records work, timing, resources, and outcomes.

In plain words
What is it for?
Use it to inspect a finished task, write a retrospective, or handle an existing retrospective result.
Why use it?
It helps reveal wasted time, repeated attempts, expensive steps, and weaknesses in how people and agents worked together.

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

task-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.

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Task Retrospective

本 Skill 是 buildr.task-retrospective/v2 的默认 provider。Agent负责复盘、当前事实重评与后续承接;Retrospective Application只负责terminal校验与SQLite current Result/处置状态,Task来源关系只通过selected buildr.task-record/v2 provider维护。

1. 恢复任务事实

确认 canonical Workspace 和正式 Task ID,读取 Task Record;Task 必须是 completedabandoned。使用当前Workspace matching retained Buildr controller invocation执行bundled inspect;不得使用candidate cliInvocation、resource payload root或checkout内部driver:

<controller-command> <controller-args-prefix...> __internal task-retrospective inspect --task <task-id> --target <canonical-workspace>

已有Result可以重做并完整替换;没有Result只是“尚未复盘”。同时读取 dispositioncurrentDigest;不要打开SQLite;不读取、迁移或删除.buildr/asset-review/

在复盘生成前建立一次有界执行事实图,只读取当前runtime可达且与效率、重复、等待、失败恢复或人机协作直接相关的最小事实:Task Record时点与终态、适用的Development/Review/Verification current摘要、相关Execution Record/Finish timing、当前session工具结果,以及已有current reportMarkdown。已有复盘是本次重新思考的证据之一,不是必须保留的结论。没有某类事实时标记缺口,不为补齐图谱遍历全部owner、读取完整日志或增加任务消耗;同一事实已在当前上下文可用时不重复回读。该图只存在于Agent任务上下文,不写入Result之外的store、Receipt、history或分析平台。

2. 生成一份自由复盘

只基于当前session/runtime可访问的任务步骤、工具结果和最终事实,重点寻找:

  • 哪些步骤耗时最多或token消耗最大;
  • 哪些推理、检索、尝试、验证或恢复发生重复;
  • 哪些等待、阻塞或环境准备可以前移、缓存或确定化;
  • 哪些选择应更早交给人,哪些可以由workflow/harness直接确定;
  • 哪些Buildr引导本身增加了不必要工作量。

报告使用自由Markdown,不要求固定标题、评分、分类或结构化建议。Token 数据按证据可见性处理:可信可得时记录数值、来源和覆盖范围;部分可得时明确覆盖的步骤、阶段或调用及其不代表完整 Task;不可得时直接标记缺失,并继续使用耗时、重复尝试、等待、工具调用和人机协作等可观察事实。不得为了补齐 Token 数字回放完整上下文、读取隐藏推理、强制估算、新增采集流程或增加任务消耗;其他精确成本数据不可见时同样写明缺口并区分观察事实与推断。不得声称读取隐藏推理、完整对话、完整工具日志或后台事件。

用户或团队给出的同类任务耗时参考区间,只作为当前任务复杂度下的比较、解释和优化背景;报告应说明适用范围及偏离原因,不把它固化为通用产品阈值、Result字段、gate、pass/fail标准或自动缩减验证范围的依据。

确定性流程候选

每次生成或重做复盘都主动判断是否存在确定性流程候选,但报告仍是自由Markdown,不要求固定标题、候选数组或评分。可信候选必须有重复证据,或单次已经造成高成本/高风险,并同时说明:

  • closed输入、唯一Owner、明确停止条件、可验证结果与幂等/有界恢复;
  • 哪些机械步骤可由Application、CLI workflow、checker或test确定化;
  • 哪些目标、业务判断、风险取舍和授权仍由人和Agent保留;
  • 预期节省、失败风险、证据局限与建议资产落点。

候选必须通过Core哲学过滤:Buildr应该约束Agent不要做错事,而不是要求Agent必须通过Buildr才能做事。 要求普通动作必须经过Buildr、把推荐路径变成唯一合法路径、建立通用许可层/生命周期gate、自动替代专业判断或自动修改Rule/Skill/workflow的方向,不得作为可固化候选;说明违反的authority/判断边界后保留Agent在现有授权与安全边界内直接执行的路径。证据不足、仍依赖业务语义、边界无法闭合或收益不足时,如实保留为普通优化方向或说明没有可信候选,不为填充报告虚构候选。

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.

task-retrospective is a skill published in the GitHub repository BuildrAI/Buildr (24 stars, last pushed yesterday), licensed MIT. It adds 86 tokens to every session and 2,942 once invoked, about $0.0004 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.
