What it does
PR Local Preview Maintainer is an agent skill from Undertone0809/rudder. Use when checking out, running, previewing, reviewing, or validating a GitHub pull request locally in a safe worktree, including PR preview URLs, local screenshots, readiness checks, logs, and cleanup instructions.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/runbook.md`).
It sits in Development, covering Git worktrees. It works with GitHub. The repository describes itself as: Open-source local Agent harness for self-improving agent teams: run agents, review work, and turn feedback into reusable skills. The licence is Apache-2.0.
When your agent uses it
- Validating a GitHub pull request locally in a safe worktree
- Including PR preview URLs
- Local screenshots
- Readiness checks
Example prompts
- “/pr-local-preview-maintainer”
Workflow steps
8 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit e2ba0f1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
gitghpnpmcurl
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, gh, pnpm and curl, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
PR Local Preview Maintainer loads about 1.6k tokens when it runs, and up to ~3.1k if it reads all its reference files. Until then it costs about 61 tokens; SKILL.md has 694 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

PR Local Preview Maintainer
Run pull requests in a disposable local worktree and give the user a stable preview link. The point is to let the user review the PR while protecting their current working tree and making UI changes visible.
Default Workflow
1. Preserve the current workspace
Start by checking the repository state:
git status --short --branch
gh pr view <number> --json number,title,state,headRefName,headRepositoryOwner,url,isCrossRepositoryIf the current worktree has local changes, do not run gh pr checkout there.
Create or reuse a sibling worktree instead. This avoids overwriting unrelated
work and keeps the PR preview easy to remove later.
Use a predictable path:
<repo-parent>/<repo-name>-pr-<number>For this repository, PR 8 should become:
/Users/zeeland/projects/rudder-oss-pr-8If the directory already exists, inspect it before reusing it:
git -C <worktree-path> status --short --branch
git -C <worktree-path> branch --show-currentIf it is dirty, ask only if the dirty changes conflict with the user's goal.
Otherwise, pick a suffixed path such as <repo-name>-pr-<number>-preview.
2. Check out the PR in the worktree
Create the worktree from the remote base, then check out the PR branch inside it:
git worktree add --detach <worktree-path> origin/main
gh pr checkout <number> --branch zeelandc/pr-<number>If main is not the base branch, use the PR's actual base ref. Prefer a local
branch name that makes the preview purpose clear and follows the user's branch
prefix convention when the repository defines one.
After checkout, verify:
git status --short --branch3. Install dependencies only when needed
Check whether dependencies are present:
test -d node_modules && echo node_modules-present || echo node_modules-missingIf missing, install them from the worktree:
pnpm installReport install warnings only when they affect the preview. Routine peer or bin link warnings can be mentioned briefly.
4. Choose isolated runtime settings
Before starting, inspect occupied ports and existing local runtimes:
lsof -nP -iTCP:<candidate-port> -sTCP:LISTENFor Rudder, prefer:
RUDDER_INSTANCE_ID=pr-<number>
PORT=<free-api-port>
RUDDER_EMBEDDED_POSTGRES_PORT=<free-pg-port>Use 3100 only if it is free and the user clearly wants the default instance.
If another Rudder dev runtime is already running, leave it alone and use a
separate port and instance ID.
Example:
env RUDDER_INSTANCE_ID=pr-8 PORT=3118 RUDDER_EMBEDDED_POSTGRES_PORT=54358 pnpm dev5. Start the preview so it survives hand-off
Use tmux when available. It keeps the preview alive after the assistant turn
ends and gives the user a simple way to inspect logs.
tmux new-session -d -s rudder-pr-<number> -c <worktree-path> \
'env RUDDER_INSTANCE_ID=pr-<number> PORT=<port> RUDDER_EMBEDDED_POSTGRES_PORT=<pg-port> pnpm dev'If tmux is not available, use another managed background process and capture
logs to /tmp/<repo-name>-pr-<number>.log. Do not leave an opaque process
running without telling the user how to stop it.
6. Wait for readiness
Poll the health endpoint or the app's equivalent readiness check:
curl -fsS http://127.0.0.1:<port>/api/healthIf the app has no health endpoint, use the first meaningful route and check for a successful response. For frontend-only apps, load the dev server URL and confirm it serves HTML.
When startup fails, inspect the session logs before returning:
tmux capture-pane -pt rudder-pr-<number> -S -160Fix straightforward startup issues yourself when they are local environment problems, such as missing dependencies or port conflicts. Do not edit PR source code unless the user asked for a fix.
Show full SKILL.md (263 more words)Show less
7. Decide whether UI screenshots are required
Screenshots are required when any of these are true:
- the PR title, files, or user request mentions UI, layout, pages, components, CSS, design, screenshots, visual review, browser behavior, or interaction
- changed files live under
ui/,desktop/, frontend route files, component directories, stylesheets, or public assets - the user says they want to "see" the effect
Use Browser Use for local browser inspection when available. Capture the important screen or flow after the preview is running. Store temporary screenshots outside the repository, for example:
/tmp/rudder-pr-<number>-<view>.pngFor non-UI backend/API PRs, a health check plus a task-specific API smoke check is usually enough. If the user still needs to review manually, provide the URL.
8. Hand-off format
Keep the final response short and concrete:
PR <number> is running in <worktree-path>.
Open: http://127.0.0.1:<port>
Logs: tmux attach -t rudder-pr-<number>
Stop: tmux kill-session -t rudder-pr-<number>
Health check passed: <brief status>
Screenshots: <paths or embedded images when UI changed>If screenshots were required but could not be captured, say exactly why and what verification did run.
Cleanup Requests
When the user asks to close, stop, or clean up the preview, stop only the PR preview session and verify its port is free:
tmux kill-session -t rudder-pr-<number>
lsof -nP -iTCP:<port> -sTCP:LISTENDo not remove the worktree unless the user explicitly asks for cleanup. If they do ask to remove it, verify the worktree has no uncommitted changes first.
Safety Notes
- Never use destructive Git commands in the user's main worktree to make a PR checkout succeed.
- Do not stop unrelated Rudder dev sessions just because the default port is in use; choose an isolated port instead.
- Keep PR preview data isolated with a dedicated
RUDDER_INSTANCE_ID. - If source edits become necessary, pause and state that the task has shifted from previewing a PR to fixing it.
