zhihu-parallel-pr-workflow

name: zhihu-parallel-pr-workflow description: Coordinate Zhihu++ issue and PR implementation through subagents with isolated git worktrees, off-host Android AVD validation, real screenshots, Chinese PR creation, and main-agent-only review/coordination. Use when the user asks to fan out issues, maximize parallel subagent work, implement multiple Zhihu++ features or fixes, validate on $off-android-avd-ci-debug, or automatically open PRs from worker branches.

Zhihu Parallel PR Workflow

Core Contract

Use this skill for high-throughput Zhihu++ issue work. The main agent must coordinate; worker subagents must implement.

• The main agent may triage issues/PRs, assign scopes, create worktrees, track remote AVD capacity, review returned diffs, and summarize status.
• The main agent must not directly implement code, commit, push, or create PRs for a worker-owned issue unless the user explicitly overrides this boundary.
• Each worker owns exactly one issue or one tightly related issue bundle, in exactly one branch/worktree.
• Workers are not alone in the codebase: tell them not to revert unrelated changes, and to keep write scopes disjoint from other workers.
• Prefer many independent workers over one broad worker, but do not assign overlapping files or features to multiple workers.

Daemon Ban

Do not use any Gradle, Kotlin compiler, build, watch, or long-lived helper daemon in the main checkout or any worker worktree. Daemon processes retain heap across parallel workers and can freeze the machine.

• Every Gradle command in this workflow must use --no-daemon.
• Every Gradle command that compiles Kotlin must also pass -Dkotlin.compiler.execution.strategy=in-process so it does not start a Kotlin compiler daemon.
• Prefer bounded one-shot commands only. Do not run --continuous, watch mode, dev servers, background Gradle processes, or any command intended to stay resident.
• Before a batch and after heavy validation, stop existing Gradle daemons with ./gradlew --stop || true. This cleanup command is allowed because it terminates daemons rather than relying on them.
• Worker prompts must repeat this rule explicitly; if a worker reports validation without --no-daemon, send it back to rerun validation correctly.

Startup

1. Record start time with date '+%Y-%m-%d %H:%M:%S %Z'.
2. Read repo instructions that apply to /Users/zhaoliyan/IdeaProjects/Zhihu, especially AGENTS.md.
3. Read $off-android-avd-ci-debug before any UI or AVD validation.
4. Inspect current checkout, open PRs, and open issues:
   • git status --short --branch
   • git worktree list --porcelain
   • gh pr list --state open --limit 80 --json number,title,headRefName,baseRefName,isDraft,url
   • gh issue list --state open --limit 80 --json number,title,labels,updatedAt,url
5. Run remote AVD health checks once per batch:
   • /Users/zhaoliyan/.agents/skills/off-android-avd-ci-debug/scripts/off-avd-ci-debug.sh status
   • /Users/zhaoliyan/.agents/skills/off-android-avd-ci-debug/scripts/off-avd-ci-debug.sh boot-check
   • If boot-check fails, inspect remote logs before assigning UI verification.
6. Stop any existing Gradle daemons before assigning workers:
   • ./gradlew --stop || true

Candidate Selection

Choose issues critically, not literally. Rank by user impact, feasibility, current PR overlap, blast radius, and testability.

• Skip or defer issues already covered by open PRs unless the task is to review or replace that PR.
• Split unrelated issues across workers.
• Bundle only when the same files and UX path are clearly shared.
• Prefer bug fixes and narrow UX wins before vague platform rewrites.
• For UI/nav/settings changes, require workers to read docs/ai-ui-design-guide.md and NavDestination.kt before editing.

Worktree Rules

Create one worktree per worker from current origin/master.

git fetch origin master --prune
git worktree add .worktrees/<short-name> origin/master -b codex/<short-name>
cp local.properties .worktrees/<short-name>/local.properties 2>/dev/null || true

Use unique branch names such as:

• codex/issue-444-account-history
• codex/issue-445-main-tab-reselect
• codex/issue-440-content-block-spacing

Never give two workers the same worktree. Never let a worker edit the main checkout unless the user explicitly says so.

Worker Prompt Template

Give each worker a self-contained prompt:

Use the Zhihu++ repo at <absolute worktree path>. You own issue #<number>: <title>.

Hard rules:
- Read AGENTS.md before editing.
- For UI/nav/settings work, read docs/ai-ui-design-guide.md and NavDestination.kt before editing.
- Do not touch unrelated files or revert changes you did not make.
- Keep helpers only when they carry real behavior; remove thin wrappers.
- Implement in this worktree only.
- Do not use any daemon: no Gradle daemon, Kotlin compiler daemon, build daemon, watch mode, dev server, or long-lived helper process.
- Validate with ./gradlew --no-daemon -Dkotlin.compiler.execution.strategy=in-process assembleLiteDebug, then ./gradlew --no-daemon -Dkotlin.compiler.execution.strategy=in-process ktlintFormat.
- If you run any additional Gradle command, it must also include --no-daemon and -Dkotlin.compiler.execution.strategy=in-process.
- If UI changed, use $off-android-avd-ci-debug remote AVD for install/launch/UI dump or screenshot. Do not use local bare adb after choosing off.
- Produce a real screenshot for PR description if the UI is visible.
- Commit, push, and open a draft PR with Chinese title/body. Title must start with feat:, fix:, or refactor:. Include Resolves #<number> when appropriate.

Task:
<issue body, product judgement, acceptance criteria, known open PR overlaps, disjoint write scope>

Return:
- branch, commit, PR URL
- files changed
- validation commands and results
- screenshot path or PR asset URL
- risks or intentionally deferred parts

Remote AVD Validation

Use off as a short-lived runner only. Do not run multiple emulator sessions concurrently on off; coordinate AVD access in the main agent.

Minimum UI validation for each UI worker:

1. Build APK locally in the worker worktree with: ./gradlew --no-daemon -Dkotlin.compiler.execution.strategy=in-process assembleLiteDebug
2. Start a short-lived remote AVD session on off using the environment from $off-android-avd-ci-debug.
3. Install app/build/outputs/apk/lite/debug/app-lite-debug.apk.
4. Launch com.github.zly2006.zhplus.lite.
5. Wait for content; if login/disclaimer blocks the path, restore account JSON using the project launch-on-device instructions or state the blocker precisely.
6. Use .agents/skills/ui-test/llm_test_helper.py dump before taps when practical.
7. Capture a screenshot from the actual AVD and place it in the worker worktree, for example artifacts/issue-<n>-final.png.
8. Kill the remote emulator after validation: /Users/zhaoliyan/.agents/skills/off-android-avd-ci-debug/scripts/off-avd-ci-debug.sh kill

If no remote interactive runner exists for a needed step, the worker must either add a small reusable runner script in its branch or mark remote UI validation blocked and still run build/format.

PR Requirements

Workers create draft PRs themselves.

• Base must be master.
• Sync from latest origin/master before branch creation.
• PR title/body must be Chinese.
• Title prefix must be feat:, fix:, or refactor:.
• Include Resolves #<issue> when the PR closes the issue.
• UI PR descriptions must include final effect screenshots from a real app run, AVD, or reproducible UI render.
• Do not create one mega PR for unrelated issue work.

Main-Agent Review

After a worker returns:

1. Inspect git status, git show --stat, and the PR diff.
2. Check for overlap with other worker branches and open PRs.
3. Review for:
   • thin helper/wrapper regressions
   • duplicated logic
   • stale comments or wrong doc-comment style
   • broken navigation semantics
   • settings keys without runtime reads
   • UI text truncation or layout regressions
4. Confirm validation evidence and screenshot are real.
5. If a worker missed requirements, send it back to fix in the same worktree.

Shutdown

1. Ensure remote AVD cleanup: /Users/zhaoliyan/.agents/skills/off-android-avd-ci-debug/scripts/off-avd-ci-debug.sh kill
2. Stop Gradle daemons from the main checkout and every worker worktree: ./gradlew --stop || true
3. Record end time with date '+%Y-%m-%d %H:%M:%S %Z'.
4. If total runtime exceeds 5 minutes, notify: terminal-notifier -message "已完成 Zhihu++ 并行 PR 工作" -sound default
5. Final response must list each worker branch/PR, validation state, screenshots, and any blocked items.
