Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00063 | $0.00913 |
| Opus 5.5 | $0.00025 | $0.00365 |
| Sonnet 5.5 | $0.00013 | $0.00183 |
| Haiku 4.5 | $0.00006 | $0.00091 |
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 9d 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
任务复盘
任务复盘帮助人和Agent从已经结束的工作中发现执行浪费、等待、重复、错误恢复和协作问题。Agent负责分析并生成文档；Task Record只记录当前本机文档版本是否仍等待人的决定。
1. 核对真实对象
读取当前运行时（Runtime）绑定中 buildr.task-record/v4 的契约（Contract）和所选提供者（Provider），确认canonical Workspace、正式Task ID和当前Task Record。Task 必须是 completed 或 abandoned；进行中的工作可以讨论改进，但不登记为终态任务复盘。
只读取当前真正可达且与复盘相关的最小事实：Task目标与结果、当前会话工具结果、Git、代码、测试、适用Review/Verification、CI或外部业务结果。已有本机文档只是调查线索，继续判断前重新核对当前事实。
2. 生成自由Markdown
重点检查 Agent 执行时间、token 消耗、重复尝试、人机协作或 Buildr workflow/harness 效率。报告使用自由Markdown，不要求评分、固定分类、行动项或确定性流程候选。
明确区分：
- 已观察事实；
- 基于事实的推断；
- 当前缺失的数据。
Token、完整耗时或调用次数不可得时直接标记缺失并继续分析。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，不为补齐数字回放上下文、强制估算或新增采集。
用户明确授权生成文档后，把完整报告写入固定本机路径：
.buildr/local/task-retrospectives/<task-id>.md
该文件不进入Git、SQLite正文、发布物或Current Knowledge。先安全写入完整文件，再计算实际SHA-256；文件写入失败时不登记Task状态。
3. 登记当前文档
重新读取Task取得当前recordDigest，执行：
buildr task update <task-id> --retrospective-state pending-decision --retrospective-document-digest <sha256-digest> --expected-record <recordDigest> --target <workspace> --json
Application会重新读取固定文件并校验Task终态、普通文件、非符号链接、正文、大小、摘要和Task版本。登记失败时保留已生成文件，只恢复登记；不得重做已完成的复盘。
4. 查看与决定
用户只要求查看时，读取当前Task和固定Markdown并直接展示；查看零写入，不自动标记已决策。
用户明确决定继续行动时，先核对现有普通Task，复用匹配todo/active Task或展示将创建的普通Task effects并取得授权。普通Task可以在目标中引用来源Task或本机复盘路径；不建立专用来源关系。
用户明确完成决定后，重新读取Task和文档摘要，再执行：
buildr task update <task-id> --retrospective-state decided --retrospective-document-digest <sha256-digest> --expected-record <recordDigest> --target <workspace> --json
decided只表示人已决定是否继续行动，不表示改进已经实施。用户决定不行动时不创建Task，也不保存no-action说明。
文档内容变化或重新生成时，重新登记为pending-decision。只有用户明确要求解除关联时，才使用--clear-retrospective；该动作不删除Markdown。
5. 边界
本Skill不参与Task完成、交付、cleanup或OpenSpec门禁，不自动提示、生成、批量处理或关闭复盘。复盘建议不自动修改Rule、Skill、Application、CLI、测试或工作流；需要继续行动时使用普通Task和对应专业能力。
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.
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 (28 stars, last pushed yesterday), licensed MIT. It adds 63 tokens to every session and 913 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 2026-08-30.
