docs(stackoverflow): clarify read fetches answers up to --answers-limit (not 'all')

Follow-up from PR #1293 review: 'all answers' was misleading because
the implementation is limit-bounded (default 10, max 100) rather than
unbounded pagination. Spell out the actual contract — including the
accepted-answer-outside-page fallback path — so users don't expect
infinite-scroll behaviour.

Non-blocking docs-only change flagged by codex-mini1 + First-principles-1
during #1293 review.

 ### Features
 
+* **observation** — add trace artifact primitives, `browser console`, `browser network --since/--follow/--failed`, and adapter `--trace=retain-on-failure` for failure-retained browser evidence.
+* **autofix** — retire `OPENCLI_DIAGNOSTIC`; adapter repair now uses `--trace retain-on-failure`, trace `summary.md`, and error-envelope trace metadata.
 * **browser** — `bind` attaches `bound:*` workspaces to user-owned Chrome tabs without taking over window lifecycle; `sessions` reports `idleMsRemaining: null` for bound workspaces because they do not schedule idle close timers. ([#1169](https://github.com/jackwener/opencli/issues/1169), [#929](https://github.com/jackwener/opencli/issues/929))
 * **browser lifecycle** — owned browser workspaces now lease tabs inside a shared dedicated automation container instead of owning one Chrome window per workspace; lease state is persisted for MV3 service-worker reconciliation and idle cleanup is backed by alarms.
 * **web read** — make page extraction render-aware: same-origin iframe content is merged into the Markdown source, `--wait-for` can wait inside main/iframe documents, `--wait-until networkidle` waits for captured requests to settle, and `--diagnose` reports frames, empty containers, and API-like XHRs for shell/AJAX pages.

+## Extending OpenCLI
+
+If you want to add your own commands, start with the [Extending OpenCLI guide](./docs/guide/extending-opencli.md). README keeps this short; the guide covers the directory layout, source-control model, and install commands.
+
+| Need | Recommended path |
+|------|------------------|
+| Keep personal website commands in your own Git repo | `opencli plugin create` + `opencli plugin install file://...` |
+| Quickly draft a private local adapter | `opencli browser init <site>/<command>` in `~/.opencli/clis/` |
+| Modify an official adapter locally | `opencli adapter eject <site>` + `opencli adapter reset <site>` |
+| Publish or install third-party commands | `opencli plugin install github:user/repo` |
+| Wrap an existing local binary | `opencli external register <name>` |

+ *   3. Click "发微博" button to open the inline compose editor
+ *   4. Wait for textarea editor to appear
+ *   5. Fill text content via CDP type
+ *   6. Optionally upload images via CDP setFileInput
+ *   7. Click the publish button
+ *   8. Poll for success/failure feedback
+ *
+ * Usage:
+ *   opencli weibo publish "Hello from OpenCLI! #opencli"  # publishes immediately

+When an AI agent uses `opencli <site> <command>` and the command fails because the site changed DOM, API, or response schema, the agent should automatically repair the adapter and retry without human intervention or pre-written spec files.
 
-### Why the simpler approach
+From first principles, the agent needs five things:
 
-The previous design (PR #863) required pre-authoring `command-specs.json` with verify checks, safety profiles, and failure taxonomy before any command could be repaired. This created a chicken-and-egg problem: you can only repair commands you've already written specs for.
+1. The failing command it just ran.
+2. The structured error envelope from stderr.
+3. The adapter source path.
+4. Browser runtime evidence: actions, page state, network, console, screenshot.
+5. A verify oracle: re-run the same command.
 
-From first principles, the agent already has everything it needs:
-1. **The failing command** — it just ran it
-2. **The error output** — stdout/stderr
-3. **The adapter source** — resolved via `RepairContext.adapter.sourcePath`
-4. **Diagnostic context** — DOM snapshot, network requests (via `OPENCLI_DIAGNOSTIC=1`)
-5. **A verify oracle** — re-run the same command

+## Prerequisites

+- Chrome running with [Browser Bridge extension](/guide/browser-bridge) installed
+- Logged in to [claude.ai](https://claude.ai)
+
+## Caveats
+
+- This adapter drives the Claude web UI in the browser, not an API
+- `claude read` queries the current automation tab; pair it with `--live` on the prior command (or chain after `claude detail <id>`) so the tab stays on the conversation between invocations
+- `--model opus` requires a paid Claude plan; on a free-tier account the adapter surfaces a usage error rather than silently falling back
+- The default Sonnet 4.6 model uses Adaptive thinking by default; `--think` is the explicit switch but Claude may still invoke thinking for complex prompts even when not requested
+- Adaptive-thinking and file-thumbnail widgets render duplicated label paragraphs (`Thought process` / `View uploaded image`) at the top of the response; these are stripped automatically so the row value is the actual answer
+- File upload is constrained by the daemon HTTP body limit (1 MB; `src/daemon.ts:152`); files up to ~700 KB raw work reliably, larger files (e.g. high-res images) may fail with `ECONNRESET`
+- Long responses (code, essays) may need a higher `--timeout`

+### Notes on collections
+
+- `instagram saved` without `--collection` returns the unsegmented "All posts" bucket (same as the original behaviour).
+- With `--collection <name>` it resolves the name to an id via `/api/v1/collections/list/`, then fetches `/api/v1/feed/collection/{id}/posts/`. Match is case-insensitive after trimming. An unknown name throws an error that lists the available names.
+- `instagram collection-create <name>` calls `POST /api/v1/collections/create/` with a multipart `name` field. Instagram silently accepts duplicate names — the API just returns a new `collection_id` each time, so dedupe client-side if you care.
+- `instagram collection-delete <name-or-id>` calls `POST /api/v1/collections/{id}/delete/`. Pass either a case-insensitive collection name or a numeric `collection_id`. If the name resolves to multiple collections (e.g. duplicates from `collection-create`), the adapter throws and lists the candidate ids so you can disambiguate by passing the id explicitly. Unknown names list the available collections in the error message.
+- Saving an existing post directly into a named collection in one shot is not exposed by the web app's documented endpoints (`/api/v1/web/save/{pk}/save/` only writes to "All posts"). Use `instagram save` first, then move the post in the UI, or extend with the `/api/v1/collections/{id}/edit/` mutation.

+## Caveats
+
+- Stack Exchange API has a 300/day quota per IP for unauthenticated
+  requests. A `read` call uses up to 4 quota units (question, question
+  comments, answers, batched answer comments), or 5 when the accepted answer
+  must be fetched separately.
+- `--answers-limit` and `--comments-limit` are bounded to 1-100, matching the
+  Stack Exchange API page size limit. If batched answer comments would be
+  partial, the command fails fast instead of returning an incomplete thread.
+- Bodies are returned as HTML; this adapter strips tags and decodes named
+  / decimal / hex HTML entities for plain-text consumption.

 ## Core Modules
 
-### Registry (`src/registry.ts`)
-Central command registry. All adapters register their commands via the `cli()` function with metadata: site, name, description, domain, strategy, args, columns.
+### CLI Surface
 
-### Discovery (`src/discovery.ts`)
-CLI discovery and manifest loading. Discovers commands from TypeScript adapter files, parses pipelines, and registers them into the central registry.
+- `src/main.ts` — process entrypoint
+- `src/cli.ts` — top-level command tree and built-in command groups
+- `src/completion.ts` / `src/completion-fast.ts` — shell completion
 
-### Execution (`src/execution.ts`)
-Command execution: argument validation, lazy loading of adapter modules, and executing the appropriate handler function.
+### Discovery, Registry, Execution
 
-### Commander Adapter (`src/commanderAdapter.ts`)
-Bridges the Registry commands to Commander.js subcommands. Handles positional args, named options, browser session wiring, and output formatting. Isolates all Commander-specific logic so the core is framework-agnostic.
+- `src/discovery.ts` — discovers built-in adapters, generated adapters, plugins, and manifests
+- `src/registry.ts` — central command registry
+- `src/registry-api.ts` — adapter-facing registration helpers
+- `src/execution.ts` — argument validation, lazy loading, and command execution
+- `src/commanderAdapter.ts` — bridges registry metadata into Commander subcommands
+- `src/output.ts` — `table`, `json`, `yaml`, `md`, `csv` formatting
+- `src/serialization.ts` — registry and manifest serialization helpers
 
-### Browser (`src/browser.ts`)
-Manages connections to Chrome via the Browser Bridge WebSocket daemon. Handles JSON-RPC messaging, tab management, and extension/standalone mode switching.
+### Browser and Runtime
 
-### Pipeline (`src/pipeline/`)
-The pipeline engine. Processes declarative steps:
-- **fetch** — HTTP requests with cookie/header strategies
-- **map** — Data transformation with template expressions
-- **limit** — Result truncation
-- **filter** — Conditional filtering
-- **download** — Media download support
+- `src/runtime.ts` — shared command runtime and target resolution
+- `src/daemon.ts` — lifecycle and bridge behavior for the local daemon
+- `src/doctor.ts` — browser bridge diagnostics
+- `src/observation/` — trace artifacts, redaction, and structured runtime evidence
+- `src/interceptor.ts` — interception helpers for browser-backed strategies
+- `src/browser/` — Browser Bridge connection and browser-side primitives
 
-### Output (`src/output.ts`)
-Unified output formatting: `table`, `json`, `yaml`, `md`, `csv`.
+### Pipeline Engine
 
-## Authentication Strategies
+- `src/pipeline/executor.ts` — pipeline execution
+- `src/pipeline/template.ts` — template expansion
+- `src/pipeline/transform.ts` — transform helpers
+- `src/pipeline/steps/` — concrete steps such as:
+  - `fetch`
+  - `download`
+  - `browser`
+  - `intercept`
+  - `tap`
+  - `transform`
 
-OpenCLI uses a 3-tier authentication strategy:
+### Adapter and Extension Surfaces
 
-| Strategy | How It Works | When to Use |
-|----------|-------------|-------------|
-| `public` | Direct HTTP fetch, no auth | Public APIs (HackerNews, BBC) |
-| `cookie` | Reuse Chrome cookies via Browser Bridge | Logged-in sites (Bilibili, Zhihu) |
-| `header` | Custom auth headers | API-key based services |
-| `intercept` | Network request interception | GraphQL/XHR capture (Twitter) |
-| `ui` | DOM interaction via accessibility snapshot | Desktop apps, write operations |
+- `clis/` — built-in site adapters
+- `src/plugin.ts` / `src/plugin-manifest.ts` / `src/plugin-scaffold.ts` — plugin install, metadata, scaffold
+- `src/external.ts` / `src/external-clis.yaml` — external CLI passthrough and installable tools
+- `src/electron-apps.ts` — desktop / Electron app support
 
-## Directory Structure
+## Command Sources
 
+OpenCLI merges commands from multiple places into one registry:
+
+| Source | Location | Examples |
+|---|---|---|
+| Built-in adapters | `clis/` | `twitter`, `bilibili`, `reddit`, `chatgpt-app` |
+| Generated / local adapters | `~/.opencli/clis/` | user-authored adapters |
+| Plugins | `~/.opencli/plugins/` | community-contributed commands |
+| External CLIs | `src/external-clis.yaml` + local registrations | `gh`, `docker`, `vercel` |
+
+The user sees one unified command tree through `opencli list`.
+
+## Connectivity Modes
+
+### Browser Bridge mode
+
+Primary path for browser-backed commands:
+
+```text
+opencli process
+  ↔ local daemon
+  ↔ Browser Bridge extension
+  ↔ logged-in Chrome / Chromium
 ```

+
+This path is used for:
+
+- cookie-backed websites
+- browser automation primitives
+- interactive browser verification
+
+### Direct CDP mode
+
+Used when OpenCLI talks directly to a Chrome or Electron debugging endpoint through `OPENCLI_CDP_ENDPOINT`.
+
+Typical uses:
+
+- remote Chrome
+- headless Chrome
+- Electron desktop adapters
+
+## Authentication / Access Strategies
+
+OpenCLI currently uses these access strategies:
+
+| Strategy | Purpose |
+|---|---|
+| `public` | direct fetch with no login |
+| `cookie` | reuse browser session cookies |
+| `header` | custom authenticated headers |
+| `intercept` | capture the app's own network responses |
+| `ui` | DOM / accessibility driven interaction |
+
+The key distinction is operational:
+
+- `public`, `header` favor direct network access
+- `cookie`, `intercept`, `ui` depend on a live browser or desktop surface
+
+## High-Risk Change Zones
+
+Changes in these files usually affect broad command behavior:
+
+- `src/cli.ts`
+- `src/commanderAdapter.ts`
+- `src/discovery.ts`
+- `src/execution.ts`
+- `src/runtime.ts`
+- `src/daemon.ts`
+- `src/plugin.ts`
+- `src/external.ts`
+- `src/pipeline/**`
+
+These areas deserve targeted tests first, then broader validation when the change crosses module boundaries.
+
+## Mental Model
+
+The simplest accurate model is:
+
+1. OpenCLI discovers command definitions.
+2. It registers them into one command registry.
+3. It resolves each invocation through execution + runtime.
+4. It reaches the target through one of:
+   - network fetch
+   - Browser Bridge
+   - direct CDP
+   - external CLI passthrough
+5. It formats the result into a stable output surface.
+
+That is the architecture to preserve when refactoring.

+# Documentation Audit — 2026-05
+
+This document reviews the current long-form docs, README surfaces, and developer guides in `opencli`. It focuses on stale facts, internal contradictions, and documentation structure that now causes drift.
+
+## Scope
+
+- `README.md`
+- `README.zh-CN.md`
+- `docs/`
+- `skills/` references that are linked from user-facing docs
+
+## Executive View
+
+The docs are usable, but they are drifting in four visible ways:
+
+1. **Hard-coded counts and feature claims are stale.**
+2. **Developer docs describe an older architecture and older test layout.**
+3. **English and Chinese docs are no longer updated with the same rigor.**
+4. **Some pages still describe deleted concepts or old workflows.**
+
+The highest-value work is:
+
+1. Fix the stale facts in `README*`, `docs/index.md`, `docs/zh/index.md`, and `docs/guide/getting-started.md`.
+2. Rewrite `docs/developer/testing.md` and `docs/developer/architecture.md` against current `main`.
+3. Make English and Chinese entry docs derive from the same source-of-truth checklist.
+4. Stop writing command/adapters counts by hand unless they are generated.
+
+## Priority 0 — Clearly stale or incorrect
+
+### 1. Adapter / site counts are stale across multiple entry points
+
+Affected files:
+
+- `README.md`
+- `README.zh-CN.md`
+- `docs/guide/getting-started.md`
+- `docs/comparison.md`
+
+Current problems:
+
+- `README.md` and `README.zh-CN.md` still say `90+` adapters.
+- `docs/guide/getting-started.md` still says `87+` pre-built adapters.
+- `docs/comparison.md` still says `87+` sites.
+
+Current reality:
+
+- `node dist/src/main.js list --format json | jq 'map(.site) | unique | length'` returns `106`.
+
+Why this matters:
+
+- These are the first pages people read.
+- The mismatch is easy to notice and weakens trust in the rest of the docs.
+- These values will keep drifting if we maintain them manually.
+
+Recommended fix:
+
+- Replace all hard-coded counts with one of:
+  - `100+`
+  - `100+ sites`
+  - `over 100 registered sites`
+- Best option: generate this number into docs at release time or avoid explicit counts entirely.
+
+### 2. `docs/developer/testing.md` is materially out of date
+
+Affected file:
+
+- `docs/developer/testing.md`
+
+Current problems:
+
+- It says adapter tests live in `clis/**/*.test.{ts,js}`.
+- The file examples name adapter tests such as:
+  - `clis/zhihu/download.test.ts`
+  - `clis/twitter/timeline.test.ts`
+  - `clis/reddit/read.test.ts`
+  - `clis/bilibili/dynamic.test.ts`
+- Those files do not exist.
+- It says E2E coverage is `5` files.
+- Current reality is `11` E2E files.
+- It presents `npm test` as the main local gate, while current team rule is to prefer the smallest sufficient test set instead of default full-suite runs.
+
+Current reality from the repo:
+
+- `find src -name '*.test.ts' | wc -l` → `60`
+- `find clis -iregex '.*\\.test\\.(ts|js)$' | wc -l` → `0`
+- `find tests/e2e -name '*.test.ts' | wc -l` → `11`
+- `find tests/smoke -name '*.test.ts' | wc -l` → `1`
+
+Why this matters:
+
+- This page is the main developer testing contract.
+- A new contributor following it will get the wrong mental model of the test layout.
+- It encourages a heavier default test habit than the team currently wants.
+
+Recommended fix:
+
+- Rewrite the page from current files, not from remembered structure.
+- Separate:
+  - `fast local checks`
+  - `targeted validation`
+  - `full CI coverage`
+- Remove nonexistent adapter test examples.
+- Add a short rule:
+  - local default = smallest sufficient validation
+  - full-suite = broader refactor, shared runtime changes, or CI
+
+### 3. `docs/developer/architecture.md` describes an older system shape
+
+Affected file:
+
+- `docs/developer/architecture.md`
+
+Current problems:
+
+- It refers to `src/browser.ts`, but that file does not exist.
+- The directory structure block says `src/clis/`, but adapters live at top-level `clis/`.
+- The architecture diagram is too simplified for the current system and omits important pieces such as:
+  - `daemon.ts`
+  - `external.ts`
+  - `plugin.ts`
+  - `electron-apps.ts`
+  - update check / diagnostics / runtime detection paths
+- It says “3-tier authentication strategy” but lists `5` strategies.
+
+Why this matters:
+
+- This is the page people read to understand the project.
+- Once architecture docs are stale, all deeper docs become harder to trust.
+
+Recommended fix:
+
+- Rewrite this page around current modules:
+  - command discovery and registry
+  - execution
+  - browser / daemon bridge
+  - external CLI integration
+  - plugin system
+  - desktop / CDP path
+  - pipeline engine
+- Replace the static tree with a curated module map that matches current filenames.
+- Change “3-tier” to a neutral label like `authentication strategies`.
+
+### 4. Home pages still mention deleted concepts
+
+Affected files:
+
+- `docs/index.md`
+- `docs/zh/index.md`
+
+Current problems:
+
+- Both home pages say:
+  - `explore`
+  - `synthesize`
+  - `cascade`
+- `docs/developer/ai-workflow.md` explicitly says those commands do not exist and that the skill drives the loop.
+
+Why this matters:
+
+- The home page is currently teaching a product vocabulary that the actual CLI does not have.
+- This creates immediate confusion for users who go from docs to terminal.
+
+Recommended fix:
+
+- Replace those phrases with current concepts:
+  - `browser primitives`
+  - `adapter-authoring skill`
+  - `verify loop`
+- Keep the homepage aligned with `docs/developer/ai-workflow.md`.
+
+### 5. Chinese getting-started page lists a deleted built-in command
+
+Affected file:
+
+- `docs/zh/guide/getting-started.md`
+
+Current problem:
+
+- It says built-in commands include `list、explore、validate...`
+- `explore` is not a current built-in command.
+
+Why this matters:
+
+- This is a hard user-facing error.
+
+Recommended fix:
+
+- Replace the example list with current built-ins such as:
+  - `list`
+  - `validate`
+  - `verify`
+  - `browser`
+  - `doctor`
+  - `plugin`
+  - `adapter`
+
+## Priority 1 — Inconsistent or incomplete
+
+### 6. Installation pages are inconsistent about runtime support and update flow
+
+Affected files:
+
+- `README.md`
+- `README.zh-CN.md`
+- `docs/guide/installation.md`
+- `docs/zh/guide/installation.md`
+
+Current problems:
+
+- `README.md` says Node `>= 21` or Bun `>= 1.0`.
+- `docs/guide/installation.md` and `docs/zh/guide/installation.md` only mention Node.
+- `README.md` documents skill refresh on update.
+- `docs/zh/guide/installation.md` only documents package update and omits skills refresh.
+
+Why this matters:
+
+- Entry docs should agree on install prerequisites and upgrade procedure.
+
+Recommended fix:
+
+- Pick one official runtime support statement and reuse it everywhere.
+- If Bun is supported, add it consistently to guide pages.
+- Mirror the post-update skill refresh guidance in the install/update guides.
+
+### 7. README and docs still use top-level tables and examples that will drift by hand
+
+Affected files:
+
+- `README.md`
+- `README.zh-CN.md`
+
+Current problems:
+
+- The “Built-in Commands” section is manually curated and already partially selective.
+- The surrounding copy still frames it like a broad current snapshot.
+
+Why this matters:
+
+- Manual command snapshots go stale quickly in a repo with active adapter growth.
+
+Recommended fix:
+
+- Reframe the section as:
+  - “Representative built-in commands”
+  - “Sample sites”
+- Keep `opencli list` and `docs/adapters/index.md` as the full registry surface.
+
+### 8. `docs/comparison.md` contains stale scale claims
+
+Affected file:
+
+- `docs/comparison.md`
+
+Current problem:
+
+- It still says `87+` sites.
+
+Why this matters:
+
+- Comparison pages shape market positioning.
+- Stale numbers make the project look less maintained than it is.
+
+Recommended fix:
+
+- Remove exact numbers from comparison copy unless they are generated.
+
+## Priority 2 — Structural drift risks
+
+### 9. English and Chinese docs are drifting independently
+
+Most visible examples:
+
+- `docs/index.md` and `docs/zh/index.md` both kept the deleted `explore / synthesize / cascade` language.
+- `docs/zh/guide/getting-started.md` contains a stale built-in command example that should have been caught by parity review.
+- `README.md` and `README.zh-CN.md` both carry the same stale adapter count.
+
+Why this keeps happening:
+
+- We have mirrored content with no explicit parity checklist.
+- Updates land in one place and rely on memory for the rest.
+
+Recommended fix:
+
+- Introduce a small doc parity checklist for any change that touches:
+  - `README.md`
+  - `README.zh-CN.md`
+  - `docs/index.md`
+  - `docs/zh/index.md`
+  - `docs/guide/*`
+  - `docs/zh/guide/*`
+- Add one PR checklist item:
+  - “Did this change require an English/Chinese mirror update?”
+
+### 10. Core product pages mix generated facts with narrative copy
+
+Examples:
+
+- command counts
+- site counts
+- test counts
+- lists of built-in commands
+
+Why this matters:
+
+- Numbers and command inventories drift faster than narrative guidance.
+
+Recommended fix:
+
+- For fast-changing facts:
+  - generate them
+  - or generalize them
+- Reserve hand-written docs for:
+  - mental models
+  - workflows
+  - constraints
+  - trade-offs
+
+## Suggested rewrite order
+
+### Pass 1 — Fix trust-breaking errors
+
+1. `README.md`
+2. `README.zh-CN.md`
+3. `docs/index.md`
+4. `docs/zh/index.md`
+5. `docs/guide/getting-started.md`
+6. `docs/zh/guide/getting-started.md`
+7. `docs/comparison.md`
+
+### Pass 2 — Rebuild the technical source-of-truth pages
+
+1. `docs/developer/testing.md`
+2. `docs/developer/architecture.md`
+3. `docs/guide/installation.md`
+4. `docs/zh/guide/installation.md`
+
+### Pass 3 — Prevent the next round of drift
+
+1. Add a docs parity checklist to PR workflow.
+2. Remove exact counts from hand-written copy unless generated.
+3. Decide which pages are authoritative for:
+   - install
+   - browser bridge
+   - testing
+   - architecture
+   - AI workflow
+
+## Concrete edits I would make next
+
+### Small fast edits
+
+- Replace all `87+` / `90+` claims with `100+`.
+- Remove `explore / synthesize / cascade` from both home pages.
+- Remove `explore` from `docs/zh/guide/getting-started.md`.
+- Align install docs on Node/Bun support and skill refresh.
+
+### Medium rewrites
+
+- Rewrite `docs/developer/testing.md` from current filesystem state.
+- Rewrite `docs/developer/architecture.md` from current module boundaries.
+
+### Process fix
+
+- Add a lightweight “doc drift” checklist to PRs that touch command surface, runtime support, testing strategy, or adapter discovery.
+
+## Bottom line
+
+The docs do not need a ground-up rewrite. They need a focused trust repair pass on entry pages, then a source-of-truth rebuild for testing and architecture, then a small process change so counts and mirrored pages stop drifting.

-测试分为三层，全部使用 **vitest** 运行：
+- `tests/e2e/`
+- `src/commanderAdapter.test.ts`
+- `src/registry.test.ts`
+- `src/execution.test.ts`
+- `src/validate.ts` / `opencli validate`

----
+推荐顺序：
 
-## 当前覆盖范围
+1. 改动命令文案、输出格式、参数解析：
+   - 跑对应单元测试
+   - 跑一条真实 CLI 命令做 spot check
+2. 改动 adapter 发现、注册、验证逻辑：
+   - 跑 `src/registry.test.ts`
+   - 跑 `src/execution.test.ts`
+   - 跑 `opencli validate`
+3. 改动 browser / daemon / runtime：
+   - 跑对应 `src/*test.ts`
+   - 必要时补一条 `tests/e2e/*` 或手动 `opencli browser ...` 验证
+4. 改动共享底层、跨多个模块、或 merge 前需要更高信心：
+   - 再扩大到 `npm test`
 
-### 单元测试与 Adapter 测试

-### 快速核对命令
-
-需要刷新测试清单时，直接以仓库文件为准：
+## 常用命令
 
 ```bash
-find src -name '*.test.ts' | sort
-find tests/e2e -name '*.test.ts' | sort
-find tests/smoke -name '*.test.ts' | sort
+# 类型检查
+npx tsc --noEmit
+
+# 编译产物
+npm run build
+
+# 跑一个目标测试文件
+npx vitest run src/<target>.test.ts
+
+# 全量 vitest projects
+npm run test:all
+
+# E2E
+npm run test:e2e
+
+# 适配器注册 / schema 校验
+node dist/src/main.js validate
 ```
 
----
-
-## 本地运行测试
-
-### 前置条件
+如果你明确要跑 adapter project，也可以执行：
 
 ```bash
-npm ci                # 安装依赖
-npm run build         # 编译（E2E / smoke 测试需要 dist/src/main.js）
-```
-
-### 运行命令
-
-```bash
-# 默认本地测试口径（unit + extension + adapter）
-npm test
-
-# 只跑 adapter project
 npm run test:adapter
-
-# 全部 E2E 测试（会真实调用外部 API / 浏览器）

-### 浏览器命令本地测试须知
+## 当前 E2E 文件
 
-- opencli 通过 Browser Bridge 扩展连接已运行的 Chrome 浏览器
-- E2E 测试通过 `tests/e2e/helpers.ts` 里的 `runCli()` 调用已构建的 `dist/src/main.js`
-- `browser-public.test.ts` 使用 `tryBrowserCommand()`，站点反爬或地域限制导致空数据时会 warn + pass
-- `browser-auth.test.ts` 验证 **graceful failure**，重点是不 crash、不 hang、错误信息可控
-- 如需测试完整登录态，保持 Chrome 登录态并安装 Browser Bridge 扩展，再手动运行对应测试
-- 对依赖具体 host 页面上下文的 browser adapter，除了单测外，还应手动验证真实命令，并把必要的 target host 约束写进 adapter docs / troubleshooting
-- 对会主动导航页面的 browser commands，手动验证时优先串行执行；多个 CLI 进程同时连到同一个 CDP target 可能互相覆盖导航，制造假的 adapter 故障
+当前 `tests/e2e/` 包含：

-## 如何添加新测试
+如果这个列表变化，以仓库文件为准：
 
-### 新增 Adapter（如 `clis/producthunt/trending.ts`）
-
-1. 根据 adapter 类型，在对应测试文件补一个 `it()` block
-
-```typescript
-// 如果 browser: false（公开 API）→ tests/e2e/public-commands.test.ts
-it('producthunt trending returns data', async () => {
-  const { stdout, code } = await runCli(['producthunt', 'trending', '--limit', '3', '-f', 'json']);
-  expect(code).toBe(0);
-  const data = parseJsonOutput(stdout);
-  expect(Array.isArray(data)).toBe(true);
-  expect(data.length).toBeGreaterThanOrEqual(1);
-  expect(data[0]).toHaveProperty('title');
-}, 30_000);
+```bash
+find tests/e2e -name '*.test.ts' | sort
 ```
 
-```typescript
-// 如果 browser: true 但可公开访问 → tests/e2e/browser-public.test.ts
-it('producthunt trending returns data', async () => {
-  const data = await tryBrowserCommand(['producthunt', 'trending', '--limit', '3', '-f', 'json']);
-  expectDataOrSkip(data, 'producthunt trending');
-}, 60_000);
+## 当前值得优先覆盖的区域
+
+以下改动最容易引入回归：
+
+- `src/cli.ts`
+- `src/commanderAdapter.ts`
+- `src/discovery.ts`
+- `src/execution.ts`
+- `src/runtime.ts`
+- `src/daemon.ts`
+- `src/plugin.ts`
+- `src/external.ts`
+- `src/pipeline/**`
+
+这类改动优先补：
+
+- 精准单元测试
+- 一条真实 CLI 验证路径
+- 必要时再扩大到 `npm test`
+
+## 手动验证建议
+
+文档或命令面改动后，优先做 2 到 4 条真实命令 spot check，例如：
+
+```bash
+node dist/src/main.js --help
+node dist/src/main.js list --format json
+node dist/src/main.js plugin --help
+node dist/src/main.js doctor --help
 ```
 
-```typescript
-// 如果 browser: true 且需登录 → tests/e2e/browser-auth.test.ts
-it('producthunt me fails gracefully without login', async () => {
-  await expectGracefulAuthFailure(['producthunt', 'me', '-f', 'json'], 'producthunt me');
-}, 60_000);
+浏览器相关改动再补：
+
+```bash
+node dist/src/main.js browser --help
+node dist/src/main.js browser tab list
 ```
 
-### 新增管理命令（如 `opencli export`）
+## CI 角色
 
-在 `tests/e2e/management.test.ts` 添加测试；如果新命令会影响输出格式，也同步补 `tests/e2e/output-formats.test.ts`。
+CI 负责更大范围的回归信心，本地负责最快闭环。
 
-### 新增内部模块
+适合交给 CI 的内容：
 
-在对应源码旁创建 `*.test.ts`，优先和被测模块放在同一目录下，便于发现与维护。
+- 更大的命令面回归
+- 多环境差异
+- E2E 稳定性
+- smoke 检查
 
-### 决策流程图
+适合本地优先做的内容：
 
-```text
-新增功能 → 是内部模块？ → 是 → src/ 下加 *.test.ts
-                ↓ 否
-         是 CLI 命令？ → browser: false? → tests/e2e/public-commands.test.ts
-                              ↓ true
-                        公开数据？ → tests/e2e/browser-public.test.ts
-                              ↓ 需登录
-                        tests/e2e/browser-auth.test.ts

-## 浏览器模式
-
-opencli 通过 Browser Bridge 扩展连接浏览器：
-
-| 条件 | 模式 | 使用场景 |
-|---|---|---|
-| 扩展已安装 / 已连接 | Extension 模式 | 本地用户，连接已登录的 Chrome |
-| 无扩展 token | CLI 自行拉起浏览器 | CI、无登录态或纯自动化场景 |

-
-## 站点兼容性
-
-GitHub Actions 的美国 runner 上，部分站点会因为地域限制、登录要求或反爬而返回空数据。当前 E2E 对这些场景采用 warn + pass 策略，避免偶发站点限制把整条 CI 打红。
-
-| 站点 | CI 表现 | 常见原因 |
-|---|---|---|
-| `hackernews`、`bbc`、`v2ex`、`bloomberg` | 通常返回数据 | 公开接口或公开页面 |
-| `yahoo-finance`、`google` | 通常返回数据 | 页面公开，但仍可能受限流影响 |
-| `bilibili`、`zhihu`、`weibo`、`xiaohongshu`、`xueqiu` | 容易空数据 | 地域限制、反爬、登录要求 |
-| `reddit`、`twitter`、`youtube` | 容易空数据 | 登录态、cookie、机器人检测 |
-| `smzdm`、`boss`、`ctrip`、`coupang`、`linux-do` | 结果波动较大 | 地域限制、风控或页面结构变动 |
-
-> 如果需要更稳定的浏览器 E2E 结果，优先使用具备目标站点网络可达性的 self-hosted runner。

+# Extending OpenCLI
+
+OpenCLI has five extension paths. Pick the path based on where you want the source code to live and how you want commands to be shared.
+
+| Goal | Use | Source location | Command surface |
+|------|-----|-----------------|-----------------|
+| Build a personal website command in your own Git repo | Local plugin | Your project directory, symlinked into `~/.opencli/plugins/` | `opencli <plugin> <command>` |
+| Quickly draft a private adapter on this machine | User adapter | `~/.opencli/clis/<site>/<command>.js` | `opencli <site> <command>` |
+| Edit an official adapter locally | Adapter override | `~/.opencli/clis/<site>/` | `opencli <site> <command>` |
+| Publish or install third-party commands | Plugin | Git repo, installed into `~/.opencli/plugins/` | `opencli <plugin> <command>` |
+| Wrap an existing local binary | External CLI | `~/.opencli/external-clis.yaml` | `opencli <tool> ...` |
+
+## Personal commands in your own Git repo
+
+Use a local plugin when you want the code to stay in a normal project directory and be managed by Git.
+
+```bash
+opencli plugin create my-cnn
+cd my-cnn
+git init
+opencli plugin install file://$(pwd)
+opencli my-cnn hello
+```
+
+`plugin install file://...` creates a symlink under `~/.opencli/plugins/`. Your source files stay in your project directory, so edits and commits happen there.
+
+This is the recommended path for custom commands you own long-term.
+
+## Private adapters in `~/.opencli/clis`
+
+Use a user adapter when you want the fastest local adapter loop and do not need a separate project directory.
+
+```bash
+opencli browser init cnn/top
+# edit ~/.opencli/clis/cnn/top.js
+opencli browser verify cnn/top
+opencli cnn top
+```
+
+User adapters are loaded from:
+
+```text
+~/.opencli/clis/<site>/<command>.js
+```
+
+This path is convenient for quick local automation. For code you want to version, review, or share, prefer a plugin.
+
+If the command takes required positional args and no fixture exists yet, seed the first verify run explicitly:
+
+```bash
+opencli browser verify instagram/collection-create --write-fixture --seed-args opencli-verify
+opencli browser verify example/detail --write-fixture --seed-args '["https://example.com/item/1", "--limit", 3]'
+```
+
+`--seed-args` is only used when the fixture has no `args`. Once the fixture is written, `opencli browser verify` reads args from `~/.opencli/sites/<site>/verify/<command>.json`.
+
+## Local overrides for official adapters
+
+Use `adapter eject` when you want to customize an existing official adapter.
+
+```bash
+opencli adapter eject twitter
+# edit ~/.opencli/clis/twitter/*.js
+opencli adapter reset twitter
+```
+
+Files in `~/.opencli/clis/<site>/<command>.js` override packaged adapters with the same `site/command` on this machine. `opencli browser verify <site>/<command>` also runs the local override, so a passing local verify does not prove that the packaged adapter was changed.
+
+The packaged `cli-manifest.json` only describes bundled adapters. User adapters are discovered at runtime and do not need manifest entries.
+
+After copying a local fix into the repository for a PR, remove the local copy or run `opencli adapter reset <site>` after merge. Otherwise the local file keeps shadowing future package updates. `opencli doctor` warns when it detects this shadowing.
+
+## Plugins for sharing commands
+
+Plugins are third-party command packages. They can be installed from GitHub, any git-cloneable URL, or a local directory.
+
+```bash
+opencli plugin install github:user/opencli-plugin-my-tool
+opencli plugin install https://github.com/user/opencli-plugin-my-tool
+opencli plugin install file:///absolute/path/to/plugin
+opencli plugin list
+opencli plugin update --all
+opencli plugin uninstall my-tool
+```
+
+Each plugin directory is scanned for `.ts` and `.js` command files. TypeScript plugins are transpiled during install.
+
+See [Plugins](./plugins.md) for manifest fields, TypeScript examples, update behavior, and monorepo publishing.
+
+## Multiple custom sites in one repo
+
+For a Git-hosted plugin collection, declare sub-plugins in `opencli-plugin.json` and install from GitHub:
+
+```json
+{
+  "plugins": {
+    "cnn": { "path": "packages/cnn" },
+    "reuters": { "path": "packages/reuters" }
+  }
+}
+```
+
+```bash
+opencli plugin install github:user/opencli-plugins
+opencli plugin install github:user/opencli-plugins/cnn
+```
+
+For local development, install each sub-plugin directory directly:
+
+```bash
+opencli plugin install file:///absolute/path/opencli-plugins/packages/cnn
+opencli plugin install file:///absolute/path/opencli-plugins/packages/reuters
+```
+
+Local `file://` installs expect the target directory itself to be a valid plugin with command files. For a monorepo root, push it to GitHub and install it with the GitHub monorepo flow.
+
+## External CLI passthrough
+
+Use external CLI registration when the command already exists as a binary on your machine and you want it available through `opencli`.
+
+```bash
+opencli external register my-tool \
+  --binary my-tool \
+  --install "npm i -g my-tool" \
+  --desc "My internal CLI"
+
+opencli my-tool --help
+```
+
+External CLIs pass stdio and exit codes through to the underlying binary.
