name: 'Skill: Run skill template'
description: Template file for the Run skill generator showing the frontmatter and section structure for a project-specific run skill
ccVersion: 2.1.145
-->
---
name: run-<unit-name>
description: Build, run, and drive <unit-name>. Use when asked to start <unit-name>, run its tests, build it, take a screenshot of its UI, or interact with the running app.
---
<One-sentence description: what this is and how an agent drives it.
Name the handle here "drive it via
`.claude/skills/run-<unit-name>/driver.mjs` under xvfb" for a desktop
app, or "start the dev server then drive it via `chromium-cli`" for a
web app so an agent knows where to look first.>
<If the unit isn't at repo root:>
All paths below are relative to `<unit-dir>/`.
## Prerequisites
<System-level requirements. The exact `apt-get install` line you ran
not a generic list, the one that actually worked. Target Ubuntu.>
```bash
sudo apt-get update
sudo apt-get install -y <packages-you-actually-installed>
```
<Runtime versions if they matter:>
```bash
# Example: Node 20 via nvm, Python 3.12 via uv, etc.
```
## Setup
<One-time setup after clone: install deps, configure, apply any
patches (feature-gate overrides, config stubs) with the exact command.>
```bash
<commands>
```
<Env vars required vs optional, with sensible defaults:>
```bash
export FOO_API_KEY=... # required — get from <where>
export BAR_MODE=dev # optional — default is prod
```
## Build
<Skip if no separate build step. Otherwise the exact command:>
```bash
<command>
```
## Run (agent path)
<This is the section a future agent actually uses. If you built a
driver/REPL/smoke script, this documents how to launch it and what it
does. If the app is simple enough that `curl` or a one-liner suffices,
that one-liner goes here.>
```bash
<launch-the-driver-or-smoke-script>
```
<For REPL-style drivers, show the tmux wrapping. Poll for a ready marker
between send-keys and capture-pane faster than a fixed sleep and fails
loudly instead of capturing a half-rendered screen:>
```bash
tmux new-session -d -s app -x 200 -y 50
tmux send-keys -t app '<launch command>' Enter
timeout 30 bash -c 'until tmux capture-pane -t app -p | grep -q "<ready-marker>"; do sleep 0.2; done'
tmux send-keys -t app '<first driver command>' Enter
tmux capture-pane -t app -p
```
<Where artifacts land (screenshots, logs) absolute paths:>
Screenshots → `/tmp/shots/`. Logs → `/tmp/<app>.log`.
<If the driver has commands, a table:>
| command | what it does |
|---|---|
| `<cmd>` | <description> |
## Run (human path)
<If meaningfully different from the agent path. Brief agents won't
use this, humans can figure it out.>
```bash
<command> # → <what happens>. <how to stop>.
```
## Test
```bash
<command>
```
<Expected result "N suites pass", or specific known-flaky tests.>
---
<Optional sections below include only if relevant and only with
content you actually hit, not generic advice.>
## Gotchas
<Non-obvious traps. The things that look like they should work but
don't, with the workaround. If this section is generic, delete it.>
- **<specific thing>** — <why it breaks><what to do instead>
## Troubleshooting
<Symptom fix. Only errors you actually encountered.>
- **<exact error message or symptom>**: <cause>. <fix>.

NOTE ON THE FRONTMATTER ABOVE:
- Replace <unit-name> in both `name:` and `description:`. The `name:`
becomes the slash command (/run-<unit-name>) and must match the
directory name.
- The `description:` is what Claude scans to decide whether to load this
skill automatically. Keep the verbs — "start," "run," "build," "test,"
"screenshot" — they're what an asking agent will actually type.
NOTE ON THE DRIVER:
- If you wrote a driver script, it lives in this same directory (next
to this file) by default. Reference it from the Run section.
- For a web app there's usually no driver file — the `chromium-cli`
heredoc in the Run section is the harness.
- If the driver grows into something the project's test suite wants —
shared launch helpers, a real e2e harness — move it to scripts/ or
e2e/ in the unit, and update the paths here. The skill stays put.
