gsp-phase-transition（gsp 相变）

The calling skill provides phase name and output directory. This skill reads STATE.md, renders the transition, and returns. The calling skill handles routing (AskUserQuestion, E2E auto-invoke, etc.) after this skill completes.

Input: Phase name + output directory path from the invoking skill Output: Terminal output with pipeline progress, completion banner, and file tree Agent: None — inline rendering

The invoking skill provides:

• Phase name — which phase just completed (e.g., "discover", "strategy", "build")
• Output directory — path to the phase's output files

Look up the completion message from the defaults table. If the invoking skill provided a custom message, use that instead.

Step 1: Read STATE.md

Determine context by reading the brand or project STATE.md:

• Which pipeline (branding or project)?
• Which phases are complete?
• Brand/project name?

Use Glob to find STATE.md: .design/branding/*/STATE.md or .design/projects/*/STATE.md.

Step 2: Pipeline progress line (conditional)

Show the pipeline line only when 2+ phases are complete. If this is the first phase completed, skip the pipeline line.

Styling

• ◆ for completed phases
• ◈ for next phase
• ◇ for pending phases
• ─── connecting phases

  {brand-or-project-name}
  ◆ discover ─── ◆ strategy ─── ◈ identity ─── ◇ guidelines

Branding phases

discover ─── strategy ─── identity ─── guidelines

If audit phase exists (evolve mode), prepend: audit ───

Project phases

brief ─── research ─── design ─── critique ─── build ─── review

Step 3: Completion banner + file tree

  ◆ {phase} complete — {completion_message}

    {phase_dir}/
    ├── {file1}.md
    ├── {file2}.md
    └── INDEX.md

  ──────────────────────────────

Read the actual output directory to list real files.

File tree rules

• Root is the phase directory name followed by /
• Files sorted alphabetically, directories first
• INDEX.md always listed last
• Use ├── for all items except the last, which uses └──
• Subdirectories show their contents with │ continuation

Final phase

If all phases in the pipeline are complete, add fully pretty. after the divider.

Step 4: Return

Return control to the calling skill. Do NOT present routing options — the calling skill owns routing.
