| description | Decomposes project requirements into well-scoped planning units for /shipwright-plan. Generates CLAUDE.md and .shipwright/agent_docs for the target project.
TRIGGER when: user wants to start a new project, define requirements, create a project spec, decompose a project into components, scaffold a new application, set up project structure, analyze requirements, or extend an existing project with new features that need full planning.
DO NOT TRIGGER when: user asks to implement code (/shipwright-build), run tests (/shipwright-test), fix a bug or make a small change (/shipwright-iterate), deploy (/shipwright-deploy), generate a changelog (/shipwright-changelog), plan implementation details for an existing spec (/shipwright-plan), or design UI mockups (/shipwright-design). |

Shipwright Project Skill
Decomposes project requirements into well-scoped components for /shipwright-plan.
Enhanced fork of deep-project with profile-aware decomposition and project scaffolding.
This Kern is a thin orchestrator โ section headers + cross-references to
references/*.md. Read the references on-demand when the corresponding
step fires. The agent reads Kern fully at startup; references are loaded
when their step is reached.
CRITICAL: First Actions
Governing rules: Read and follow shared/constitution.md (ALWAYS /
ASK FIRST / NEVER boundaries).
BEFORE using any other tools, complete the First Actions checklist
in references/first-actions.md:
- A. Print intro banner
- A.1 Startup check (first turn only โ
shipwright_run_config.json
presence; if missing, AskUserQuestion + END TURN)
- A.2 Startup check next turn (handle Full Pipeline vs Standalone
Spec answer)
- B. Detect scope (Full Application vs Extension)
- C. Detect input mode (File / Inline / Chat)
- D. Detect invocation mode (pipeline vs standalone)
- E. Discover plugin root + run setup script
- F. Handle session state (new vs resume)
- G. Print session report
The reference file is authoritative for the exact prompts, banner text,
shell invocations, and resume-step mapping. Do not paraphrase or
condense โ copy verbatim from the reference into your output where
required.
Single-Session Gate Discipline
When this phase runs as a phase-runner subagent under the single-session
pipeline (shipwright_run_config.json mode: "single_session"), interactive
AskUserQuestion gates โ incl. A.1 and Step 4 โ follow a per-gate policy.
Resolve each before stopping:
uv run "${SHIPWRIGHT_PLUGIN_ROOT}/../../shared/scripts/tools/resolve_gate_policy.py" \
--phase project --list --project-root .
Apply the effective_policy: auto-default โ proceed with the default_answer
(no END-TURN; e.g. the interview is answered from the seed, the split manifest is
auto-approved); orchestrator-approve / hard-stop โ STILL STOP and hand back to
the orchestrator (never auto-answer โ e.g. a missing Supabase secret). Outside a
driven single-session run (standalone / adopted) every gate is interactive. Full contract:
shared/prompts/single-session-gate-discipline.md.
Step 0: Phase Session Context Recovery
See references/step-0-context-recovery.md.
If the orchestrator handed you a phaseTaskId (you were dispatched as a
phase-runner subagent by /shipwright-run), run get_phase_context.py --phase-task-id <id> BEFORE Step 1. Otherwise (standalone), continue
with Step 1.
Step 1: Interview
See references/step-1-interview.md for
the full step. Detailed interview guidance is in
references/interview-protocol.md.
Goal: Surface the user's mental model of the project and combine it
with Claude's intelligence.
Assumptions-first (before the first clarifying question): list your
inferred assumptions explicitly โ web-app vs CLI, stack, persistence, auth
model โ and ask the user to correct them. See the "Surface Inferred
Assumptions First" pre-phase in
interview-protocol.md.
Context to read depends on input mode (File / Inline / Chat). For
Extension scope, read ALL existing project context (CLAUDE.md,
.shipwright/agent_docs/*, all .shipwright/planning/*/spec.md).
Interview depth ranges Light (1-3) for Extensions to Deep (8-15)
for Chat-mode Full Applications. One AskUserQuestion per question.
Checkpoints:
- Write
{planning_dir}/shipwright_project_interview.md (transcript)
- Inline/Chat only: also write
{planning_dir}/requirements.md
Step 2: Split Analysis
See references/split-heuristics.md for
evaluation criteria.
Goal: Determine if project benefits from multiple splits or is a
single coherent unit.
Context to read:
{initial_file} - The original requirements{planning_dir}/shipwright_project_interview.md - Interview transcript
Step 3: Dependency Discovery & project-manifest.md
See references/project-manifest.md
for manifest format.
Goal: Summarize splits, map relationships and write the project
manifest.
Checkpoint: Write {planning_dir}/project-manifest.md with Claude's
proposal.
Step 4: User Confirmation
See references/step-4-confirmation.md.
Goal: Get user approval on split structure.
Present the manifest and use AskUserQuestion to get the user's feedback.
If changes requested, update project-manifest.md directly and
re-present. On approval, proceed to Step 5.
Step 5: Create Directories
See references/step-5-create-dirs.md.
Goal: Create split directories from the approved manifest.
uv run "{plugin_root}/scripts/checks/create-split-dirs.py" --planning-dir "{planning_dir}"
Checkpoint: Directory existence. Resume from Step 6 if directories
exist.
Step 6: Spec Generation
See references/step-6-spec-gen.md.
Detailed file formats in
references/spec-generation.md.
Goal: Write spec files for each split directory.
Checkpoint: Spec file existence.
Step 7: Project Scaffolding (NEW โ Shipwright Enhancement)
See references/step-7-scaffolding.md.
Detailed CLAUDE.md + .shipwright/agent_docs generation in
references/project-scaffolding.md.
Goal: Generate CLAUDE.md and .shipwright/agent_docs/ for the
target project.
This step only runs for Full Application scope. Extensions already
have these files.
Key sub-flows (see reference for the verbatim shell commands and
templates):
- Profile detection โ match interview against
{plugin_root}/../../shared/profiles/ JSONs; supabase-nextjs is the
primary supported profile.
- Generate CLAUDE.md,
architecture.md, decision_log.md,
conventions.md, and .claude/rules/*.md.
- Phase-router hook โ
suggest_iterate is registered in
shipwright-iterate; no project-level install. Cleanup of legacy
.claude/settings.json UserPromptSubmit entries is documented in
the reference.
- Write config via
write-project-config.py.
- Write interview decisions to
decision_log.md via the shared
write_decision_log.py tool โ once per project-specific decision.
- Supabase setup (supabase-nextjs profile only) โ
supabase init,
supabase link --project-ref, verify .supabase/ exists.
- GitHub Repo Hygiene โ enable
delete_branch_on_merge=true if a
GitHub remote exists.
Checkpoint: CLAUDE.md existence + supabase/config.toml existence
(supabase-nextjs only).
Step 8: Completion
See references/step-8-completion.md
for the full verification list, the C1/C2/C3/C4/C5 + phase_history
canon, and the final summary banner.
Verification (all must pass before "phase complete"):
- All declared splits have spec.md files
- project-manifest.md exists and lists all splits with execution order
- CLAUDE.md exists (Full Application only)
.shipwright/agent_docs/ directory exists with all 5 files (Full
Application only)- Spec Completeness Gate โ Scope + FRs + NFRs in each spec.md
- Manifest-Spec Consistency โ bijection between manifest and
spec.md files
Phase complete โ update pipeline state by running the
C1/C2/C3/C5 + phase_history block from
references/step-8-completion.md, then
call the orchestrator update-step to mark the project phase complete.
Error Handling
See references/error-handling.md for
the invalid-input-file and session-conflict prompts.
