opencli-adapter-author is an agent skill for writing OpenCLI site adapters from recon and API discovery through verify-ready clis/site/name.js implementations.

About

opencli-adapter-author guides agents through writing OpenCLI adapters for new sites or new commands on existing sites, replacing opencli-oneshot and opencli-explorer. The workflow targets a sub-30-minute loop from zero to passing opencli browser verify using opencli browser commands, doctor, init, and verify with trace-friendly debugging flags. A coverage-matrix pre-check confirms browser-visible HTTP/JSON/HTML data without realtime push requirements. Agents must produce a strategy note before coding, choosing among PUBLIC_API, COOKIE_API, PAGE_FETCH, INTERCEPT, DOM_STATE, or UI_SELECTOR with contract stability evidence. The decision tree covers site memory reads, site-recon patterns, api-discovery sections, endpoint validation, field decoding, output column design, adapter skeleton generation under clis/site/name.js, and verify with autofix loops. Browser adapters prefer --trace on --keep-tab true --window foreground for retained tabs and summary.md artifacts. References include strategy-selection.md, site-memory, field-conventions, and decode-playbook for unstable internal endpoints.

  • Targets a 30-minute closed loop to opencli browser verify using existing browser, doctor, init, and verify commands.
  • Requires a strategy note before coding with six strategy classes and contract stability evidence.
  • Decision tree covers site memory, recon patterns, API discovery, endpoint validation, and field decoding.
  • Documents maintenance-cost guidance favoring PUBLIC_API and COOKIE_API over unstable PAGE_FETCH or INTERCEPT.
  • Debugging guidance uses --trace on, --keep-tab true, and --window foreground for browser adapters.

How do I add a new OpenCLI adapter for a site with the right fetch strategy and a passing browser verify loop?

Author OpenCLI site adapters end to end from recon and API discovery through field decoding, adapter coding, and browser verify.

Who is it for?

Developers extending OpenCLI with new site adapters who need structured recon, strategy selection, and verify loops.

Skip if: Skip for ad-hoc browser driving without an adapter; use opencli-browser instead.

When should I use this skill?

User asks to write or extend an OpenCLI adapter, add a site command, or debug browser verify failures.

What you get

A verified OpenCLI adapter with documented strategy, decoded fields, and passing opencli browser verify.

  • Verified site adapter under clis/
  • Strategy note with contract evidence

By the numbers

  • Each OpenCLI adapter follows a fixed three-part structure: declaration, args, and func

你是要给一个站点写 adapter 的 agent。这份 skill 目标:从零到通过 `opencli browser verify` 的 30 分钟内闭环

全程用现有工具:opencli browser * / opencli doctor / opencli browser init / opencli browser verify。没有新命令。

调试浏览器型 adapter 时,优先直接带上 --trace on --keep-tab true --window foreground--trace on 每轮都落 trace artifact,summary.md 是失败/成功复盘入口;--keep-tab true --window foreground 让 tab lease 保留且浏览器窗口在前台,方便核对最终页面状态。

---

前置:看你落在哪

先拿 coverage-matrix.md 快速自测。三个问题:

1. 数据在浏览器里看得到吗?(否 → 先解决鉴权) 2. 数据是 HTTP/JSON/HTML 吗?(否 → 不在 skill 范围) 3. 需要实时推送吗?(是 → 找同数据 HTTP 接口;没有就放弃)

三个都 yes 继续。

顶层决策树

先定 strategy,再写 adapter。 每次进入 Step 3/4 后、写代码前,必须产出一段 strategy note。没有这段 note,不要开始写 clis/<site>/<name>.js

核心判断不是 "API 比 DOM 高级",而是 数据源有没有外部契约。实测维护成本显示:公开/官方接口最稳;UI/DOM 语义通常也有用户可见契约;站内未文档化 XHR/GraphQL/signature endpoint 最容易漂。不要为了 "API-first" 把稳定的 UI/DOM 实现盲目迁到无契约内部接口。

Strategy: PUBLIC_API | COOKIE_API | PAGE_FETCH | INTERCEPT | DOM_STATE | UI_SELECTOR
Contract: stable | visible-ui | internal-unstable
Evidence:
- observed request/state: <endpoint / state global / UI-only signal>
- auth source: <none / browser cookie / csrf from meta / localStorage / page runtime>
- replay result: <status + content-type + non-empty sample shape>

If Strategy is PAGE_FETCH or INTERCEPT:
- why PUBLIC_API / COOKIE_API are unavailable:
- why UI_SELECTOR / DOM_STATE are not safer:
- why the maintenance cost is acceptable:

Strategy classes:

Strategy契约级别用在什么时候证据要求
PUBLIC_APIstable不需要登录,Node-side fetch 直接拿到目标数据200 + JSON/HTML 含目标数据,不是埋点/广告
COOKIE_APIstableNode-side fetch + page.getCookies() / header helper 能拿数据cookie/CSRF 来源清楚,replay 非空
UI_SELECTORvisible-uipublish/upload/click/表单,或页面语义比内部接口更稳selector 有语义锚点;错误路径是 typed error
DOM_STATEvisible-ui数据在 hydration state / bootstrap JSON / SSR HTML 里state key / script JSON / HTML 结构明确
PAGE_FETCHinternal-unstable只能在页面上下文 fetch 才能复用 same-origin/session/runtimeopencli browser eval fetch(...) 非空;必须解释为什么避不开内部接口
INTERCEPTinternal-unstable请求签名复杂,但页面自己能自然发出请求触发 UI 后能截到目标 response;必须解释为什么 UI/DOM 不够

选择规则:优先 PUBLIC_API / COOKIE_API。如果 UI/DOM 语义稳定,不要强行升级到 PAGE_FETCH / INTERCEPT。只有公开/官方接口不可用、UI/DOM 无法表达目标数据或操作时,才承担无契约内部接口的维护成本。

实测:PAGE_FETCH / INTERCEPT 的 fix 频率约为 PUBLIC_API 的 7-8 倍,UI_SELECTORCOOKIE_API 同档。详细 ladder 推导、api_candidates 证据怎么填、booking #1680 等反例见 `references/strategy-selection.md`

边界:只复用页面自己已经合法获得的数据/能力。不教破解签名、不绕验证码/风控/访问控制;遇到不可复用签名(如必须由页面 runtime 生成且不能安全抽象)就降级到 UI_SELECTOR / DOM_STATE / INTERCEPT

Runbook(一步一步勾选)

[ ] 1. opencli doctor 返回 "Everything looks good"
[ ] 2. 读站点记忆:
       [ ] ~/.opencli/sites/<site>/endpoints.json 存在?里面有想要的 endpoint?
       [ ] references/site-memory/<site>.md 存在?看"已知 endpoint"节
       [ ] 命中后:**跳到第 5(endpoint 验证) + 第 7(字段核对)**,不能直接跳第 9 写 adapter
       [ ] memory 写入超过 30 天(看 `verified_at`)→ 当作过期,按冷启动走 Step 3 → 4
[ ] 3. 侦察(site-recon.md):
       [ ] **首选**:`opencli browser analyze <url>` 一步拿 pattern + 反爬 + 最近 adapter + next step
       [ ] `analyze` 结论模糊时再手跑:`open` → `wait time 2` (或 `wait xhr <regex>`) → `network`
       [ ] 定 Pattern(A / B / C / D / E)
[ ] 4. API 发现(api-discovery.md)按 Pattern 选 §:
       [ ] Pattern A → §1 network 精读
       [ ] Pattern B → §2 state 抽取 + §1 深层数据
       [ ] Pattern C → §3 bundle / script src 搜索
       [ ] Pattern D → §4 token 来源 + 降级 §5
       [ ] Pattern E → 找 HTTP 轮询接口;找不到才 §5
[ ] 5. 直接 fetch 候选 endpoint 验证:
       [ ] 返回 200
       [ ] 响应含目标数据(不是 HTML / 广告)
[ ] 6. 写 strategy note(写代码前的强制产物):
       [ ] 从 `PUBLIC_API / COOKIE_API / PAGE_FETCH / INTERCEPT / DOM_STATE / UI_SELECTOR` 选一个
       [ ] 填 Contract:`stable / visible-ui / internal-unstable`
       [ ] 填 Evidence:observed request/state、auth source、replay result
       [ ] 如果选 `PAGE_FETCH` / `INTERCEPT`,必须解释为什么 `PUBLIC_API` / `COOKIE_API` / `UI_SELECTOR` / `DOM_STATE` 都不适合
       [ ] 如果选 `UI_SELECTOR` / `DOM_STATE`,不需要为 "为什么不是 API" 过度辩护;只要说明语义锚点和 typed error 路径
[ ] 7. 字段解码:
       [ ] 自解释 → 直接用 key
       [ ] 已知代号 → field-conventions.md 查表
       [ ] 未知代号 → field-decode-playbook.md(排序键对比 / 结构差分 / 常量排查)
[ ] 8. 设计 columns(output-design.md):
       [ ] 命名 camelCase 且对齐邻居 adapter
       [ ] 类型 / 单位 / 百分比格式清楚
       [ ] 顺序:识别列 → 业务数字 → metadata
[ ] 9. 写 adapter(adapter-template.md):
       [ ] opencli browser init <site>/<name>
       [ ] 找同站点或同类型最像的 adapter,cp 过来
       [ ] 改 name / URL / 字段映射
[ ] 10. opencli browser verify <site>/<name>
        [ ] 首轮通过后立刻 `--write-fixture` 生成 `~/.opencli/sites/<site>/verify/<cmd>.json` 种子
        [ ] 手改种子:加 `patterns`(URL / 日期 / ID 格式)+ `notEmpty`(核心字段)+ 收紧 `rowCount`
        [ ] 再跑一次 `opencli browser verify <site>/<name>`,确认 ✓ matches fixture
[ ] 11. 字段值 vs 网页肉眼比对(别只看 "Adapter works!")
[ ] 12. 回写站点记忆(**verify 通过 + 肉眼比对对得上之后**,schema 见 `references/site-memory.md`):
        [ ] `endpoints.json`:以 endpoint 的短名为 key,value = `{url, method, params.{required,optional}, response, verified_at: YYYY-MM-DD, notes}`
        [ ] `field-map.json`:只追加新代号。key = 字段代号,value = `{meaning, verified_at: YYYY-MM-DD, source}`;**已存在的 key 不要覆盖**,有冲突先和网页肉眼值对齐再写
        [ ] `notes.md`:顶部追加一段 `## YYYY-MM-DD by <agent/user>`,写本次写 adapter 时遇到的新坑 / 新结论
        [ ] `verify/<cmd>.json`:**必填。** `opencli browser verify` 的期望值(args / rowCount / columns / types / patterns / notEmpty),Step 10 已经让你生成了,这里只是 checklist
        [ ] `fixtures/<cmd>-<YYYYMMDDHHMM>.json`:存一份该 endpoint 的完整响应样本(去掉 cookie / token / 用户私有字段再存),给后续字段对比 / 离线 replay 用
        [ ] 调试过程中如果在 repo / adapter 目录 dump 过临时文件(`.dbg-*.html` / `raw-*.json` / 等),**在 commit 前清干净**——这些本来就该落在 `~/.opencli/sites/<site>/fixtures/` 或 `/tmp/`

降级路径(某步卡住跳到哪)

卡在现象跳去
Step 4 API 发现network 空,__INITIAL_STATE__ 也空§3 bundle 搜 baseURL
bundle 搜不到 baseURL§5 intercept
Step 5 endpoint 验证401 / 403§4 token 排查
200 但响应是 HTML回 Step 3 换 Pattern 判断
200 但 data: []参数传错 / 接口换版,回 §1 看 network 里真实请求头
Step 7 字段解码排序键对比推不出field-decode-playbook.md §3 结构差分
还推不出先输出 raw,adapter 跑起来再迭代
Step 10 verify 失败fltt 漏了 / 字段映射错autofix skill;复现命令加 --trace retain-on-failure
某列永远是 null字段路径错了,回 Step 7
Step 10 verify fixture mismatch[pattern] row[i] 报错先肉眼比对网页值;值对 → 是 fixture pattern 太严,放宽;值不对 → 字段映射错
[column] missing column "X"实际 response 没这列(站点改版 or args 影响);重新 --update-fixture 或修 adapter
[type] actual null / undefined字段提取失败,回 Step 7 重抽;临时 fallback 用 union type `string\
Step 11 数值不对差 10000 倍单位不统一("万" vs "元")
百分比小 100 倍响应已是 0.025,不要 × 100

references/typed-errors.mdfunc 主体之前必读:5 类 typed error 落点表(ArgumentError / EmptyResultError / CommandExecutionError / AuthRequiredError / TimeoutError)+ 三大 silent anti-pattern(silent-clamp / sentinel-row / generic CliError)的反例修法

---

关键约定

  • adapter 只引 @jackwener/opencli/registry + @jackwener/opencli/errors,不用第三方
  • columns 数组和 func 返回对象 keys 完全对齐(含顺序)
  • 中间解析对象 key 不能跟 `columns` 任一项重叠(否则 silent-column-drop audit 误判,PR #1329 R1 真踩过;改成专属命名 + push row 时 destructure aliasing)
  • `browser:` field 决定 func 签名browser:false → (args)browser:true → (page, args)。搞反时 args 实际是 debug flag,所有外部参数 silent fallback 到 default(PR #1329 upstream 之前 8 个 non-browser adapter 全踩过这个)
  • 已知失败按 `references/typed-errors.md` 5-classification 抛对应 typed error;不要 silent return []不要 silent return [{sentinel}]不要 Math.max/min silent clamp 外部参数
  • 写私人 adapter 用 ~/.opencli/clis/<site>/<name>.js(免 build);要提 PR 才 copy 到 clis/<site>/<name>.js
  • 站点记忆每轮回写:没记忆 → 用 skill → 产生记忆 → 下次变 5 分钟
  • *调试过程中的原始 dump / 抓包 / HTML 样本只能落在 `~/.opencli/sites/<site>/fixtures/` 或 `/tmp/`。严禁在 repo 根目录、`clis/<site>/` 或当前工作目录留 `.dbg-.html / raw-.json / sample.` 这类临时文件**(PR diff 会带上去,别人 review 时很烦)。
  • JSDOM unit-test fixture(`clis/<site>/__fixtures__/<command>.html`)是上面那条的例外——它是有意 commit 进 repo 的 review artifact,不是临时 dump。但因此 quality bar 要更高:必须按 references/jsdom-fixture-pattern.md 的 5 步做完(含 mandatory awk 'NF>0' 空白行收紧),并 reverse-validate 一道证明 regression guard 真能挂。

---

卡住了

  • 诊断类:opencli doctor → 看 notes.md → 搜 autofix skill
  • 字段解码类:field-decode-playbook.md 全三节走完 → 先输出 raw 迭代
  • endpoint 找不到:api-discovery §5 intercept 兜底

不要猜。猜错了 verify 能通过但数据是错的,用户看到乱码才发现。
