brownfield-adopter

brownfield-adopter is a skill for Claude Code, Codex from miniidealab/openlogos. It costs 0 tokens per session (1,970 once invoked), scanned A, original, Apache-2.0.

An optional skill for scanning an existing codebase to create a factual starting baseline. A baseline records verified project structure and possible usage scenarios, without adding explanations about project history or reasons.

In plain words
What is it for?
Use it only when explicitly asking for a full baseline scan or a rescan, and use its status or recovery steps when an earlier scan was interrupted.
Why use it?
It can provide an initial map of an older project, while avoiding unsupported claims and keeping unfinished scan results separate from the official files.

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

brownfield-adopter 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 7d 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.

Skill: Brownfield Adopter(存量项目逆向建基线)

显式可选的存量项目 eager seed 加速器:用户或宿主明确要求预扫全库时,由 AI 会话/driver 逆向扫描可验证代码事实,经 openlogos baseline-seed 两阶段事务落盘。它不是 openlogos adopt 后的默认下一步,不决定项目能否创建 change;完全跳过本 Skill 时,change-writer 仍按 S39 在每次变更中补齐触达场景的正式规格。

触发条件

  • 用户明确要求「建立现状 seed」「预扫全库」「运行 baseline-seed」;或宿主明确选择 eager seed 作为扫描优化。
  • 用户对安全的 open run / 未提交 staging 明确要求续做或重扫。
  • 不得触发:仅因 openlogos adopt 完成、baseline_seed_state: required|partialnext/status 展示 seed 状态而自动派发。三态均不构成 change/plan/delta/merge/verify 前置。

前置依赖

  1. logos/logos.config.json 存在,目标模块可解析;通常为 bootstrap: adopted,但显式重扫不以 bootstrap 值替代用户意图。
  2. 具备用户/driver 授权的代码库读取能力。
  3. CLI 支持 openlogos baseline-seed begin|commit|status
  4. 任一资源/索引读取前,先在模块锁内检查并恢复未终结 commit journal;无法恢复立即报 baseline_commit_in_progress,不得开始扫描或读取半新 resources。

核心原则(不可违反)

  1. 只写可从代码忠实验证的事实:system-map(模块图/入口/依赖)+ 场景候选清单;绝不写 PRD/历史 Why。
  2. verified:false 冻结:不存在确认升级、verified:true、confirmed_*、JIT advisory 或 baseline warning。
  3. 只写 run 私有 staging:不得直接改 logos-project.yaml 或目标 logos/resources/;唯一提交者是 baseline-seed CLI。
  4. 能力缺失不伪造且不阻断 change:显式 seed 失败可重试;用户仍可直接创建 change。
  5. 安全 partial 与未终结事务分流:open run/未提交 staging 可排除后继续;prepared|committing journal 必须恢复,失败是硬操作错误,不能降级为“seed 证据不可用”。
  6. 存量代码 grandfather 边界不变:seed 是未确认事实快照,方法论硬门只约束新意图;候选按 active/tombstone/alias 维护。

执行步骤

Step 1: 确认显式意图与恢复门

确认当前请求确实要求 eager seed,而非普通 adopt→change。随后在项目根调用 seed status/恢复入口;读取目标、索引或 coverage 必须位于「取模块锁 → 检查/恢复 journal → 读取」同一锁区间。若返回 baseline_commit_in_progress,停止本 Skill,不得以代码重扫绕过可能半新的标准 resources。

Step 2: 逆向扫描并规划逻辑 manifest

仅在恢复门通过后扫描代码库,规划无内容 hash 的逻辑产物计划;必需 kind 至少含 system-mapscenario-candidates

{
  "module": "core",
  "expected": [
    { "kind": "system-map", "target_path": "logos/resources/prd/3-technical-plan/1-architecture/core-system-map.md", "candidate_keys": ["core::<hash>"] },
    { "kind": "scenario-candidates", "target_path": "logos/resources/prd/3-technical-plan/2-scenario-implementation/core-scenario-candidates.md", "candidate_keys": ["core::<hash>"] }
  ]
}

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.

brownfield-adopter is a skill published in the GitHub repository miniidealab/openlogos (72 stars, last pushed 11d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,970 tokens. 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.
