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 | $0.00058 | $0.02283 |
| Opus 5.5 | $0.00023 | $0.00913 |
| Sonnet 5.5 | $0.00012 | $0.00457 |
| Haiku 4.5 | $0.00006 | $0.00228 |
Grade A, and why
f2s-doc-final 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
执行口径：初稿/终稿统一写入
.Knowledge/stock-docs/；模板优先读取.Knowledge/template/终稿模版.md。
编排（主 / 子 agent）
subAgent/switchAgentVerification两字段语义以统一入口为唯一事实源：Cursor/Claude 读配置根rules/f2s-flow2spec-unified-entry.*；Codex 读.codex/topics/f2s-flow2spec-unified-entry.md（与上同源，flow2spec init镜像）。本节不复述。- 默认不拆子：MD / PDF → 终稿模版的连贯性最好，由主会话一气呵成完成理解、套模版与定稿。
- 可选拆子（仅当
subAgent=true且大体量 / 多文件，阈值：PDF > 50 页 或 > ~5MB 文本）：子 agent 做「套模版、排版与结构搬运」草稿；主 agent 对照终稿模版、识别缺口并向用户追问、与用户对齐并定稿 / 验收；子 agent 不得单独宣称终稿已合规。 - 不为「格式转换可独立」默认拆子：终稿合规依赖模版语义 + 业务表述，主侧验收成本通常仍在。
- 校验：落盘侧 agent 自验，本 SKILL 不绑定交叉校验。
将 PDF 或 MD 转换为《终稿模版》规范格式（spec → context）
用户会在本技能后附带至少一个参数：第一个参数为本地 PDF 文件路径或 Markdown 文件路径（必填）；第二个参数（可选）为输出文件路径，若提供则覆盖默认输出位置。请根据文件类型按下列流程执行，输出便于后续由 f2s-kb-build 技能消费的终稿风格 Markdown 文档。
终稿模版仅作提示：若存在 .Knowledge/template/终稿模版.md，可读取作为结构参考；不强制套用。
项目架构命名（优先于通用方案命名）
- 输入为
f2s-doc-arch产物，或内容明确为项目整体架构时，初稿文件名/一级标题固定为项目架构初稿.md/项目架构初稿，终稿固定为项目架构终稿.md/项目架构终稿；默认目录.Knowledge/stock-docs/。 - 此分支适用于 MD 与 PDF 两种流程；不从旧输入文件名、正文方案名、
package.json.name或仓库目录名拼接项目名前缀，也不生成项目架构初稿_终稿.md。第二参数可改变目录，文件名按对应阶段归一化，并说明实际路径。 - 项目名称只在正文描述；同名目标已存在时增量更新并保留有效内容。转换旧名称输入时不自动删除原文件或覆盖另一份不同范围文档，引用迁移需确认。
- 完成后交接
f2s-kb-build <实际目录>/项目架构终稿.md；架构 topic id 为project-architecture、标题为项目架构，拆分主题按职责命名，均不加下游项目名前缀。 - 其他能力/方案文档继续使用下述
<方案名>_初稿.md/<方案名>_终稿.md约定。
内嵌模板结构（当项目内无 .Knowledge/template/终稿模版.md 时使用）
规范要求：
- 一级标题：方案名（如
# xxx 技术方案设计）。 - 二级标题至少包含：
## 核心概念、## 业务规则、## 关键流程；其余可按需增删（如 状态与流转、接口、配置/表设计/错误码、实现位置与对接方式）。 - 核心概念：用表格列出术语、实体、关键 ID（列：概念、说明）。
- 状态与流转：若有状态机，用列表写状态及流转；若无可简述或省略。
- 业务规则：列表写约束、校验、配置项。
- 关键流程：按「用户侧或系统侧」主流程，列表写流程名、步骤简述、入口接口/方法、结果。
- 可选章节：接口、配置/表设计/错误码、实现位置与对接方式，按需保留并填写。
流程一：用户传入的是 Markdown（.md）
- 读取用户传入的
.md文件内容。 - 参考格式（不强制）：若存在
.Knowledge/template/终稿模版.md，可读取作为结构提示；否则可参考下方内嵌模板结构。 - 分析与转换：
- 理解原文主题与结构，提炼「方案名」「核心概念」「业务规则」「关键流程」及与原文相关的其他章节（如状态与流转、接口、配置/表设计/错误码、实现位置等）。
- 将内容重组为结构清晰的终稿风格 Markdown：一级标题为方案名；建议至少包含 核心概念、业务规则、关键流程 三个二级标题，其余按原文有无与需要增删；表格/列表格式可参考模版，不必完全一致。
- 若原文缺少某节，可标「（待补充）」或根据原文推断补全；若原文结构已清晰，可保留原文章节命名。
- 输出：
- 默认写入
.Knowledge/stock-docs/<方案名>_终稿.md（最终产物带_终稿标识）。 - 若用户希望指定输出路径，可在命令后附带第二个参数作为输出路径；否则用默认。
- 回复：告知用户已生成
.Knowledge/stock-docs/<方案名>_终稿.md，并提示可按f2s-kb-build继续同步.Knowledge/topics、.Knowledge/index.md（必要时manifest）。
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.

f2s-doc-final is a skill published in the GitHub repository double-coding-lab/Flow2Spec (52 stars, last pushed 6d ago), licensed MIT. It adds 58 tokens to every session and 2,283 once invoked, about $0.0002 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.
