description	LLM-assisted human-in-the-loop review. Make sense of a change, focus attention where it matters, test. Use when the user says "checkpoint", "human review", or "walk me through this change".

Checkpoint Review Workflow

Goal: Guide a human through reviewing a change — from purpose and context into details.

Your Role: You are assisting the user in reviewing a change.

Conventions

• Bare paths (e.g. step-01-orientation.md) resolve from the skill root.
• {skill-root} resolves to this skill's installed directory (where customize.toml lives).
• {project-root}-prefixed paths resolve from the project working directory.
• {skill-name} resolves to the skill directory's basename.

On Activation

Step 1: Resolve the Workflow Block

Run: python3 ${CLAUDE_PLUGIN_ROOT}/tools/lib/resolve-customization.py --skill {skill-root} --key workflow

If the script fails, resolve the workflow block yourself by reading these three files in base → team → user order and applying the same structural merge rules as the resolver:

1. {skill-root}/customize.toml — defaults
2. {project-root}/.mighty-powers/custom/{skill-name}.toml — team overrides
3. {project-root}/.mighty-powers/custom/{skill-name}.user.toml — personal overrides

Any missing file is skipped. Scalars override, tables deep-merge, arrays of tables keyed by code or id replace matching entries and append new entries, and all other arrays append.

Step 2: Execute Prepend Steps

Execute each entry in {workflow.activation_steps_prepend} in order before proceeding.

Step 3: Load Persistent Facts

Treat every entry in {workflow.persistent_facts} as foundational context you carry for the rest of the workflow run. Entries prefixed file: are paths or globs under {project-root} — load the referenced contents as facts. All other entries are facts verbatim.

Step 4: Load Config

Load config from {project-root}/.mighty-powers/config.yaml and resolve:

• implementation_artifacts
• planning_artifacts
• communication_language
• document_output_language

Step 5: Greet the User

Greet the user, speaking in {communication_language}.

Step 6: Execute Append Steps

Execute each entry in {workflow.activation_steps_append} in order.

Activation is complete. If activation_steps_prepend or activation_steps_append were non-empty, confirm every entry was executed in order before proceeding. Do not begin the main workflow until all activation steps have been completed.

Global Step Rules (apply to every step)

• Path:line format — Every code reference must use CWD-relative path:line format (no leading /) so it is clickable in IDE-embedded terminals (e.g., src/auth/middleware.ts:42).
• Front-load then shut up — Present the entire output for the current step in a single coherent message. Do not ask questions mid-step, do not drip-feed, do not pause between sections.
• Language — Speak in {communication_language}. Write any file output in {document_output_language}.

FIRST STEP

Read fully and follow ./step-01-orientation.md to begin.
