"Start the dev server, inspect the feature in browser, and iterate on polish."

Polish

Start the dev server, open the feature in a browser, and iterate. You use the feature, say what feels off, and fixes happen.

Phase 0: Get on the right branch

  1. If a PR number or branch name was provided, check it out (probe for existing worktrees first).
  2. If blank, use the current branch.
  3. Verify the current branch is not main/master.

Phase 1: Start the dev server

The scripts below ship in this skill's scripts/ directory. The Bash tool's working directory is the user's project, not the skill directory, so a bare scripts/<name> path will not resolve — invoke each by the skill's own absolute path. Every runnable block below sets SKILL_DIR inline (shell state does not persist between Bash tool calls, so each command must carry it); replace the <absolute path …> placeholder with the directory you loaded this ce-polish SKILL.md from before running.

1.1 Check for .claude/launch.json

SKILL_DIR="<absolute path of the directory containing this SKILL.md>"
bash "$SKILL_DIR/scripts/read-launch-json.sh"

If it finds a configuration, use it — the user already told us how to start the project.

1.2 Auto-detect (when no launch.json)

Identify the framework:

SKILL_DIR="<absolute path of the directory containing this SKILL.md>"
bash "$SKILL_DIR/scripts/detect-project-type.sh"

Route by type to the matching recipe reference for start command and port defaults:

| Type | Recipe | |------|--------| | rails | references/dev-server-rails.md | | next | references/dev-server-next.md | | vite | references/dev-server-vite.md | | nuxt | references/dev-server-nuxt.md | | astro | references/dev-server-astro.md | | remix | references/dev-server-remix.md | | sveltekit | references/dev-server-sveltekit.md | | procfile | references/dev-server-procfile.md | | unknown | Ask the user how to start the project |

For framework types that need a package manager, run the resolver and substitute the result into the start command:

SKILL_DIR="<absolute path of the directory containing this SKILL.md>"
bash "$SKILL_DIR/scripts/resolve-package-manager.sh"

Resolve the port:

SKILL_DIR="<absolute path of the directory containing this SKILL.md>"
bash "$SKILL_DIR/scripts/resolve-port.sh" --type <type>

1.3 Start the server

Start the dev server in the background, log output to a temp file. Probe http://localhost:<port> for up to 30 seconds. If it doesn't come up, show the last 20 lines of the log and ask the user what to do.

1.4 Open in browser

Load references/ide-detection.md for the env-var probe table. Open the browser using the IDE's mechanism (Claude Code → open, Cursor → Cursor browser, VS Code → Simple Browser).

Tell the user:

Dev server running on http://localhost:<port>
Browse the feature and tell me what could be better.

Phase 2: Iterate

This is the core loop. The user browses the feature and tells you what to improve. You fix it. Repeat until they're happy.

  • When the user describes something to fix → make the change, the dev server hot-reloads
  • When the user asks to check something → use a browser-automation capability to screenshot or inspect the page; prefer agent-browser if it's installed, otherwise use whatever the host exposes
  • When the user says they're done → commit the fixes and stop

No checklist. No envelope. Just conversation.
