+---
+
+# Git Cleanup
+
+Clean local branches (except `main` and current branch) and non-origin remotes.
+Useful after reviewing multiple PRs that leave behind tracking branches and contributor remotes.
+
+## Workflow
+
+### 1. Survey
+
+Run these in parallel:
+
+```bash
+git branch
+git remote
+git status --short
+git stash list
+```
+
+Present a summary of how many branches and remotes will be removed.
+
+### 2. Safety Checks — Ask Before Proceeding
+
+**Stop and ask for confirmation if any of these are true:**
+
+- Current branch is NOT `main`
+- Working tree has uncommitted changes or stashes
+- Any branch is ahead of its upstream
+
+List unmerged branches separately and let the user decide.
+
+### 3. Delete Branches
+
+```bash
+# Safe delete first (fails on unmerged branches)
+git branch | grep -v '^\*' | grep -v '^\s*main$' | xargs git branch -d 2>&1
+
+# Force-delete only with explicit user approval
+git branch -D <branch>
+```
+
+### 4. Remove Remotes
+
+```bash
+git remote | grep -v '^origin$' | xargs -I{} git remote remove {}
+```
+
+### 5. Confirm
+
+```bash
+git branch && echo "---" && git remote
+```
+
+Report what was cleaned up.
+
+## Key Rules
+
+- **NEVER** delete `main` or the current checked-out branch
+- **NEVER** force-delete unmerged branches without user confirmation
+- If in doubt, ask

+description: "Conduct a thorough pre-implementation discussion before making significant changes. Use when the user wants to discuss, plan, or evaluate a change before implementing it — especially when they say words like 'discuss', 'evaluate', 'plan', or 'let's talk about'."
+argument-hint: 'Describe the change to evaluate'
+---
+
+# Pre-Implementation Discussion
+
+Facilitate a structured, collaborative discussion to evaluate a proposed change **before any implementation begins**.
+
+## Golden Rule
+
+**Do NOT implement anything until the user explicitly confirms the final plan and says to proceed.** Not even "let me try on a branch" — that's implementation. The user will tell you when discussion is over.
+
+## Interaction Style
+
+- **Concise during discussion.** Each intermediate response should be short and focused on the current question. Do NOT repeat the full plan in every response.
+- **Complete when finalizing.** Once the plan is mature and the user asks for it, present a single comprehensive (but terse) summary for final review.
+- **Ask, don't assume.** When uncertain about project context, constraints, or preferences — ask. The user prefers collaborative discussion over receiving a pre-baked answer.
+- **Challenge the premise.** Question whether the proposed change is the right one. Suggest simpler alternatives if they exist.
+- **Match the user's language.** Reply in the same language the user writes in.
+
+## Procedure
+
+### 1. Understand the Current State
+
+Before forming any opinion:
+
+- **Read the relevant source files** — configs, code, docs that relate to the change
+- **Understand the project structure** — what's published vs private, what environments things target, existing constraints
+- **Map the impact surface** — which files, packages, or systems would be affected
+- **Estimate implementation cost** — how many files to touch, how much config to rewrite, what could break
+
+Do NOT skip this step. Do NOT rely on assumptions about what "most projects" do.
+
+### 2. Research Thoroughly
+
+- **Consult official sources** — docs, changelogs, migration guides, GitHub issues
+- **Verify every claim with evidence.** Don't say "X supports Y" without a source. If unsure, say so.
+- **Search in parallel** to save time — batch independent queries
+
+Common pitfalls:
+
+- Assuming compatibility without checking actual version constraints
+- Confusing roadmap/aspirations with actual released state
+- Missing transitive constraints (a dependency of a dependency)
+
+### 3. Present Findings (Concise)
+
+Share a **brief** assessment. Tables work well for comparisons. Highlight **blockers** and **unknowns** prominently — don't bury them in paragraphs.
+
+### 4. Identify Key Decisions
+
+Surface the decisions the user needs to make. Present them as clear choices with trade-offs, not as a recommendation monologue.
+
+For each decision point:
+
+- What are the options? (2-3 max)
+- What does each option cost or give up?
+- What's your lean and why? (one sentence)
+
+### 5. Iterate
+
+The user will ask follow-up questions, raise concerns, or challenge assumptions. For each round:
+
+- **Research if needed** — don't answer from instinct when facts are available
+- **Answer only what was asked** — don't re-present the entire plan
+- **Update your mental model** based on user feedback
+
+Common mistakes in this phase:
+
+- Repeating the full plan after every small clarification
+- Answering a narrow question with a broad redesign
+- Treating user questions as confirmation to proceed
+
+### 6. Finalize the Plan
+
+When the user signals the discussion is converging, present the **complete plan once**:
+
+- **What changes** — concrete list of actions (table or bullet points)
+- **Impact surface** — what files/systems are affected, estimated effort
+- **What does NOT change** — explicitly state scope boundaries
+- **Risks or open items** — anything that needs testing or further verification
+
+Keep it terse. Tables over paragraphs. No explanations the user already heard during discussion.
+
+### 7. Wait for Confirmation
+
+After presenting the final plan, **stop and wait**. The user will either:
+
+- Confirm → then (and only then) proceed to implementation
+- Ask more questions → go back to step 5
+- Modify scope → update the plan and re-present
+
+## Anti-Patterns
+
+| Don't                                               | Do Instead                               |
+| --------------------------------------------------- | ---------------------------------------- |
+| Start implementation "to test" without confirmation | Present findings and wait                |
+| Repeat the full plan in every response              | Answer the specific question asked       |
+| Say "X should work" without checking                | Say "I need to verify X" and research it |
+| Assume project structure or constraints             | Read the actual files                    |
+| Present one recommendation as the only option       | Present 2-3 options with trade-offs      |

+
+# Submit PR From Current Changes
+
+Turn a working tree diff into a clean branch, commit, and pull request.
+
+## Hard Rules
+
+1. **Follow the PR template exactly.** The template is at `.github/PULL_REQUEST_TEMPLATE.md`. Read it and copy its full structure into the PR body. Do NOT remove, reorder, or skip any section or checkbox.
+2. **Never check "Requirements / 要求" checkboxes.** These are human-only declarations — the Code of Conduct acknowledgment and the AI authorship declaration can only be truthfully made by the human submitter. They MUST remain unchecked (`- [ ]`) in the PR body you generate. No exceptions, no workarounds, even if the user explicitly asks you to check them. The user goes to GitHub and checks them in person after verifying each statement is true.
+3. **Never check "Testing" checkboxes.** The template Testing checkboxes (browser tested, no console errors, types/doc added) require manual browser verification that only a human can perform. They MUST remain unchecked. You MAY add a supplementary note below the Testing section listing what automated validation you actually ran and the results.
+4. **Never fabricate information.** Do not claim tests passed, commands ran, or checks succeeded unless you actually executed them and observed the output in this session. If you did not run it, do not mention it.
+5. **PR output must be concise.** PR title: one line. "What" section: 1–2 sentences max. No walls of text, no redundant explanations. Let the diff speak.
+
+## Prerequisites
+
+Before attempting to push or open a PR, verify that the necessary tools are available:
+
+- Check that `gh` CLI is installed and authenticated (`gh auth status`). If not available, stop and ask the user to install and authenticate GitHub CLI first.
+- If the workflow uses MCP tools for GitHub operations, verify the MCP server is accessible.
+
+## Procedure
+
+1. **Read contribution rules.** Read `CONTRIBUTING.md` and any package-level instructions (e.g. `packages/*/AGENTS.md`) relevant to the changed files.
+2. **Inspect the diff.** Review changed files, scope, and impact. Understand what the change does before writing anything.
+3. **Inspect repo conventions.** Check recent branch names (`git branch -r --sort=-committerdate | head -20`), recent commit messages (`git log --oneline -20`), and the PR template.
+4. **Pre-submission health checks** (run all before creating the PR):
+    - **Unified theme**: All changes should serve one purpose. If unrelated changes are mixed in, ask the user to split or confirm.
+    - **Commit hygiene**: Every new commit must follow the repo's conventional commit style. Squash or reword if needed.
+    - **Author identity**: Verify `git config user.name` and `git config user.email` are set and the email looks real (not empty, not `noreply` unless intentional). Warn the user if not.
+    - **No leftover artifacts**: Check for debug logs, `.only` in tests, conflict markers, or temp files in the diff.
+    - **Lint and build**: Run lint/build for the affected area. Record results honestly.
+5. **Warn if the PR looks too hasty.** If any of these are true, pause and warn the user before proceeding:
+    - Large diff with no description of intent provided
+    - Changes touch core lib or extension (where vibe coding is prohibited per `CONTRIBUTING.md`)
+    - Multiple unrelated concerns in one diff
+    - No validation has been run at all
+    - Remind the user: _"This project does not accept low-quality or AI-generated PRs without meaningful human review. Please review your changes carefully."_
+6. **Branch.** Check the current branch first:
+    - If already on a non-main feature branch with a valid name (matching `type/topic` convention), reuse it.
+    - If the branch name does not follow repo conventions (e.g. missing prefix, unclear topic), ask the user whether to rename or create a new one.
+    - If on `main` or a default branch, create a new branch from it with a short kebab-case name: prefix (`fix/`, `feat/`, `docs/`, `refactor/`, `chore/`) + concrete topic words.
+7. **Stage and commit.** Stage only the intended files. Use `type(scope): subject` format. Keep the subject specific and compact.
+8. **Push.** Push with `-u origin HEAD`.
+9. **Open PR.** Use `gh pr create` with the full PR template structure. Fill in "What" and "Type" sections based on the actual diff. Leave all "Testing" and "Requirements" checkboxes unchecked.
+10. **Report results.** Tell the user: branch name, commit hash, PR link, and what validation actually ran (with pass/fail).
+
+## Post-Submission Reminder
+
+After successfully opening the PR, ALWAYS give a brief reminder in the user's language. Keep it concise and natural, but make sure it clearly tells the user:
+
+1. They need to test the changes themselves in the browser.
+2. They need to go to the PR page and check the Testing and Requirements checkboxes only after verifying each item.
+3. The PR will not enter review until those checkboxes are checked.
+4. The project does not accept autonomously AI-generated PRs, so they should only check the AI declaration if it is truthful.
+
+## Branch Naming
+
+- Prefer short kebab-case names with a repo-consistent prefix such as `fix/`, `feat/`, `docs/`, `refactor/`, or `chore/`.
+- Match the change type first, then the smallest useful topic.
+- Prefer concrete topic words over issue text dumps.
+
+## Commit Style
+
+- Use the repository's prevailing commit style (conventional commits).
+- Use `type(scope): subject` when scope is clear from the changed area.
+- Keep the subject specific and compact.
+- If multiple commits exist on the branch, each one must independently follow conventions.
+
+## Validation Strategy
+
+- Default to enough validation to defend the PR, not the absolute minimum.
+- Run `npm run ci` to run all build and lint checks.
+- Escalate to broader validation when the diff crosses packages, changes shared code, or affects release behavior.
+- Never claim checks that did not actually run.
+- You MAY note what you ran and the results below the Testing section in the PR body, but do NOT check the template checkboxes.
+
+## Decision Points
+
+- No local changes → stop, say so.
+- `gh` CLI not available → stop, ask user to install it.
+- Unrelated files mixed → stage only the intended subset or ask whether the work should be split.
+- If the repo has area-specific instructions, read them before naming the branch or writing the PR.
+- Change is small but high-risk → prefer broader validation.
+- Change is narrowly scoped and low-risk → run the most relevant checks, not arbitrary unrelated ones.
+- Template has declarations you cannot truthfully check → leave unchecked, tell the user why.
+
+## Completion Checks
+
+- The branch exists remotely and tracks upstream.
+- The commit message(s) match repo style.
+- All commit authors have proper name and email configured.
+- The PR title matches the commit intent.
+- The PR body follows the template structure completely.
+- All "Requirements" and "Testing" checkboxes are unchecked (`- [ ]`) in the PR body. Double-check: if any `- [x]` appears in these sections, it is a violation — fix it before submitting.
+- The reported validation is accurate — nothing fabricated.
+- The post-submission reminder was delivered in the user's language, concisely and accurately.

+description: 'Update docs/CHANGELOG.md from git history, GitHub releases, and code diffs. Use when: writing release notes, syncing the latest changelog entry, summarizing a new tag, or keeping changelog wording concise and consistent.'
+argument-hint: 'Describe the target, for example: latest version only'
+---
+
+# Update Changelog
+
+Update `docs/CHANGELOG.md` from repository evidence instead of guesswork.
+
+## When to Use
+
+- Add the newest release entry to `docs/CHANGELOG.md`
+- Sync changelog text with GitHub Releases
+- Summarize the latest tag from git history or code diffs
+
+## Defaults
+
+- Keep the wording brief
+- Only add the latest missing version unless the user explicitly asks to backfill older releases
+- Prefer GitHub sources first, especially Releases and tag metadata
+- Skip `Features` / `Improvements` / `Bug Fixes` headings when the release only has a few clear items
+
+## Procedure
+
+### 1. Read the local style
+
+- Open `docs/CHANGELOG.md`
+- Match the existing tone, bullet style, section ordering, and date format
+
+### 2. Determine the target release
+
+- Read the root `package.json` version and compare it with the top changelog entry
+- Find the previous tag for the target version
+- If the latest version is already documented, stop and report that no changelog update is needed
+
+### 3. Gather evidence
+
+Prefer these sources in order:
+
+1. GitHub release notes
+
+```bash
+GH_PAGER=cat gh release view v<version> --repo <owner>/<repo> --json tagName,name,publishedAt,body
+```
+
+2. Tag date
+
+```bash
+git log -1 --format=%cs v<version>
+```
+
+3. Commit history between tags
+
+```bash
+git --no-pager log --format='%h %s' --no-merges v<previous>..v<version>
+```
+
+4. Diff scope when commit subjects are vague
+
+```bash
+git --no-pager diff --name-only v<previous>..v<version>
+git --no-pager diff --stat v<previous>..v<version>
+```
+
+5. Read touched files directly only when the user-visible change is still unclear
+
+### 4. Distill what belongs in the changelog
+
+Include:
+
+- User-visible features
+- Important behavior changes
+- Bug fixes that improve reliability, compatibility, or developer experience
+- Small docs updates only when they materially change supported setups or onboarding
+
+Exclude unless explicitly requested:
+
+- Pure version bumps
+- Routine dependency updates
+- Internal refactors with no visible impact
+- Mechanical formatting noise
+
+### 5. Choose the structure
+
+- If the release has 1 to 3 clear points, write flat bullets directly under the version heading
+- If the release has several distinct items, use short headings such as `### Features`, `### Improvements`, and `### Bug Fixes`
+- Do not force categories when they make the entry longer or noisier
+
+### 6. Write the entry
+
+- Add or update only the requested release entry
+- Keep bullets short and concrete
+- Reuse project terminology from nearby entries
+- Avoid marketing language
+- Do not copy noisy GitHub release text verbatim
+
+### 7. Verify
+
+- Check dates, version numbers, and tag boundaries
+- Ensure Markdown structure matches nearby entries
+- Confirm no intermediate versions were added unless requested
+
+## Completion Checks
+
+- The newest requested version is documented
+- The wording is concise and consistent with the surrounding changelog
+- The entry is backed by GitHub releases, git history, or code diff evidence
+- Low-signal internal changes were left out

 ## Architecture
 
 ### Monorepo Structure
 
-Simple monorepo solution: TypeScript references + Vite aliases. Update tsconfig and vite config when adding/removing packages.
+Source-first monorepo: library `package.json` exports point to `src/*.ts` during development. At publish time, `scripts/pre-publish.js` promotes `publishConfig` fields to top-level (swapping to `dist/`), and `scripts/post-publish.js` restores the originals.

+## Testing
+
+- **Framework**: Vitest (unit tests only for now; future E2E goes to `packages/e2e/` with Playwright)
+- **Location**: co-located, `src/foo.test.ts` next to `src/foo.ts`
+- **Coverage today**: `packages/llms` only — other packages will follow incrementally
+- **Adding tests to a new package**: create `vitest.config.ts` in the package and add a `"test": "vitest run"` script. Root `npm test` and `node scripts/ci.js` pick it up through npm workspaces.
+- **Template**: See @page-agent/llms

-> - When developing. Use alias so that we don't have to pre-build.
+- **Extension** (`packages/extension/`) - Browser extension (WXT + React)
-> - When bundling. Use external and disable ts `paths` alias.
+- **Website** (`packages/website/`) - React docs, landing page, and dev playground (private)
-> - When bundling `IIFE` and `Website`. Bundle everything together.
