/prd-ce:init — Greenfield Scaffold Seeder

Plant the consumer-owned scaffold for a fresh PRD-CE project. The methodology engine (lifecycle skills, the agent squad, governance hooks, readiness.py) is delivered live by the installed prd-ce plugin — it never gets copied into your repo. This skill seeds only what is yours to own and edit: PRD.md, the SoT/ graph, epics/ templates, your .claude/domain-profile.yaml, and per-agent MEMORY.md starters.

One manifest, no drift. The seed list comes from install-manifest.yaml's template_seed section — the same list install.sh (fork path) and ghm-template-sync (update path) read. This skill drives the deterministic prd-ce-init.sh so behavior is identical no matter who invokes it.

Scope (v1): greenfield only. This seeds an empty structure into a fresh repo. Mid-build and live-codebase on-ramps (entry-mode branching, graph extraction) are backlogged — see temp/plugin-conversion-plan.md. If the target already has PRD.md or SoT/ content, the seeder keeps it (non-destructive) rather than adapting to it.

Consumes

• ${CLAUDE_PLUGIN_ROOT}/templates/ — the bundled seed sources (mirrors template_seed paths) the packager ships with the plugin.
• install-manifest.yaml template_seed + never_touch — authoritative seed/skip lists.
• scripts/prd-ce-init.sh — the deterministic seeder this skill drives.

Produces

• A seeded scaffold in the target repo (no new SoT IDs — this skill places templates, it does not author specs).
• A freshly reset PRD.md (frontmatter at v0.1, today's date, no stale template_version).
• A verification report (hooks emit valid JSON; readiness.py runs).

Workflow

Phase 1 — Preflight

1. Confirm git, python3, bash are present. Warn (don't block) if the target isn't a git repo.
2. Confirm greenfield: if PRD.md or non-empty SoT/ already exist, say so and stop — the seeder will keep them untouched, so there is nothing for init to do. (Point the user at the lifecycle skills to keep building, not at re-seeding.)

Phase 2 — Wizard questions

Ask only what changes the outcome (honor the execution mode's budget):

• Target directory (default: current repo).
• Domain profile: product (default) · library · infrastructure · research. Quick mode skips this and takes the default.

Phase 3 — Seed (drive prd-ce-init.sh)

Run the deterministic seeder so behavior matches every other path:

bash "${CLAUDE_PLUGIN_ROOT}/scripts/prd-ce-init.sh" --target <DIR> --dry-run   # preview
bash "${CLAUDE_PLUGIN_ROOT}/scripts/prd-ce-init.sh" --target <DIR>             # seed

• Show the --dry-run plan first [standard+], then execute.
• The seeder skips any file that already exists (never_touch honored) and resets a freshly seeded PRD.md frontmatter to v0.1.
• After seeding, if the chosen domain profile differs from the default, update the profile: key in the seeded .claude/domain-profile.yaml [standard+].

Phase 4 — Verify (trust-but-verify)

1. Run each plugin hook against the target; assert valid JSON on stdout.
2. Run python "${CLAUDE_PLUGIN_ROOT}/scripts/readiness.py" run — a BLOCK on an empty scaffold is the gate working (no content yet), not a failure. Report the score.
3. Print next steps: customize README.md + PRD.md, then "Let's frame the problem" (v0.1).

Anti-patterns

Pattern	Fix
Hardcoding the seed file list in the skill	Drive prd-ce-init.sh; it reads template_seed
Copying the framework (skills/hooks) into the consumer repo	The plugin provides those live — seed only consumer-owned files
Overwriting an existing PRD.md/SoT/	Greenfield-only; the seeder skips what exists
Leaving PRD.md at the example's version header	Frontmatter reset to v0.1 happens automatically on a fresh seed
Treating a readiness BLOCK on a fresh scaffold as a bug	It's the gate working — report the score
