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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00029 | $0.09848 |
| Opus 5.5 | $0.00012 | $0.03939 |
| Sonnet 5.5 | $0.00006 | $0.01970 |
| Haiku 4.5 | $0.00003 | $0.00985 |
Grade A, and why
pdlc-implement 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.
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.

按设计文档实现代码
严格按照设计文档和已有的测试用例实现功能代码。
⛔ IRON LAW · 不可违反的硬门禁
以下规则为不可协商的执行约束：
- 文件必须落盘：所有带编号（功能ID / 缺陷ID）的文档，必须作为实际文件写入磁盘，不可仅在对话中输出。
- 阶段必须落章：每个阶段完成后必须在状态机
docs/.pdlc-state/<feature-id>.json追加 history，不可跳过。 - 测试必须存在：进入
/pdlc-implement前，对应测试必须存在且处于红灯状态。违反则中止。 - 自检必须执行：段二自检为强制步骤，不得以"已经很好了"为由跳过。
- 防循环：段三修复为单次，不递归。无法自动修复的问题记录到报告，继续往下走。
- 状态必推进：成功执行某 phase 后
current_stage必须变更。收尾时若发现current_stage未推进，视为失败并报错，不得静默返回（防止外层循环拿滞后的状态空转烧额度）。唯一例外：命中人工点主动 block 时，current_stage保持不变但必须写last_phase_result.ok=false+blocked_reason。
违反任一条 = 立即中止当前命令，输出违规详情，等待人工介入。
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）。
- 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>" } - 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。
- 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。 - 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。
What ships with it
3 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.

pdlc-implement is a skill published in the GitHub repository kanfu-panda/pdlc-skills (18 stars, last pushed 19d ago), licensed MIT. It adds 29 tokens to every session and 9,848 once invoked, about $0.0001 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.
