pdlc-loop-run

pdlc-loop-run is a skill for Claude Code from kanfu-panda/pdlc-skills. It costs 50 tokens per session (2,670 once invoked), scanned A, original, MIT.

An automated loop that moves a feature through TDD, implementation, and review. TDD, or test-driven development, means writing tests as part of defining and checking the code’s expected behavior.

In plain words
What is it for?
Use it to run repeated test, implementation, and review stages for a feature ID, with a maximum number of iterations and a clear stopped or blocked result.
Why use it?
It removes the need to manually coordinate repeated steps during the mechanical part of feature development. It stops when review is complete or when progress is blocked, leaving release and deployment decisions to a person.

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

pdlc-loop-run 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 19d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/pdlc-loop.sh), 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.

收敛循环引擎(loop-run)

把机械收敛段 tdd → implement → review 烧成一个自主循环:从 current_stage 出发逐阶段自动推进,直到 review_done 或被 blocked。这是 /pdlc-loop-next 之上的高层引擎——用户不必自己写 bash 循环。

非交互模式(--autonomous)

若本命令的参数含 --autonomous,本命令进入无人值守模式,按以下规则处理原本需要人应答的交互点。参数是唯一真源:不带 --autonomous 即为交互模式,一切照旧正常询问用户;绝不回读状态机 run_mode 兜底(「掉出 autonomous」是安全的失败方向)。

  1. 流程性确认(如「测试已绿是否继续」「是否覆盖已有文件」)→ 不询问,按预设默认前进,并把决策追加到状态机 history[].auto_decisions[] (写状态机的命令:推进时给状态推进脚本传 --decision "<确认点描述>=<所选默认>",可重复;脚本写成下面的样子):
    { "point": "<确认点描述>", "chose": "<所选默认>", "at": "<ISO 8601>" }
    
  2. 真需人判断(PRD 关键取舍、评审「需人工确认」项、真实循环依赖、测试与设计 / PRD 矛盾等无法安全默认的点)→ 不猜。 改测试、改检查命令让它变绿,永远不是「流程性默认」,不能记成 --decision:
    • current_stage 保持不变(不推进)
    • 写 last_phase_result.ok = false 且 blocked_reason = "<原因>"(写状态机的命令:给状态推进脚本传 --blocked "<原因>")
    • 末行输出哨兵:<<<PDLC blocked reason="<原因>">>>
    • 立即结束命令,交还人类
    • 守卫拦截也走这一条:前置守卫(缺设计文档、缺测试、测试没红等)在 --autonomous 下拦住本命令时, 不能只输出 ⛔ 就停——同样写 ok=false + blocked_reason(写明哪条守卫、缺什么)并输出哨兵。 否则状态机里仍是上一阶段的 ok=true,循环驱动只看到 current_stage 没动,会把「被拦」误报成「卡住」,真实原因丢失。
  3. 破坏性操作(发布 / 部署 / 打 tag / 触发 CI / DROP / force-push 等不可逆·外发操作)→ --autonomous 无效,仍必须人工显式确认。
  4. 顺手的 sidecar 产物(如缺失时创建 CHANGELOG.md、补全文档 PDLC-TRACE 的创建时间等本阶段职责内、可安全默认的辅助改动)→ 视为流程性默认,直接做并记入 auto_decisions[];这类改动不新增外部副作用,不属破坏性操作。

进入 autonomous 模式时,在状态机顶层写 run_mode: "autonomous" 仅供留痕(复盘区分人工 vs 循环产出)。

⛔ 终态即 review_done(设计如此):本引擎只覆盖机械收敛段。到达 review_done 即成功停机,交人工决定是否 /pdlc-ship。绝不自动进入 pdlc-ship / pdlc-deploy——发布/部署是不可逆·外发操作,永远留人(--autonomous 对它们无效)。prd/design 的关键取舍同样不在本引擎范围内。

两种运行形态

  • 默认推荐 · 外部 Runbook(真进程隔离):长跑 / 过夜 / 多 feature 并行时,用独立进程逐轮跑,每轮全新进程 = 真 fresh context 最可信。本命令可打印该 Runbook 脚本(见 usage-guide「自主循环 Runbook」)。
  • 便捷 · 插件内 Task 版(本命令默认行为):适合短收敛。每个 stage 派发给一个 fresh Task subagent(context 相对隔离),返回后读状态机决定推进 / 停 / block。

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.
