/deep-plan $ARGUMENTS

Orchestrate the full planning pipeline in the correct order. Each phase invokes an existing skill via the Skill tool and presents a checkpoint before the next phase.

This skill sequences sub-skills. It does NOT duplicate their content.

Argument Parsing

Arguments: $ARGUMENTS

Parse flags:

• --yes — Auto-answer all checkpoints with defaults (opt-in phases skip, opt-out phases run). Pass --yes to sub-skills that support it.
• --skip-reviews — Skip Phases 4-6 (deep eng + design + multi-review). Use when spec's Phase 2.5 inline reviews are sufficient.
• --no-decompose — Skip Phase 7 (Linear decomposition).
• Everything else = the feature description. Store as $FEATURE.

If $FEATURE is empty, ask: "What feature or idea do you want to plan?"

Do not proceed without a feature description.

Phase 1: Product Review (always)

Run /product-review via Skill tool with $FEATURE as arguments.

Wait for completion. The sub-skill handles its own internal checkpoints (interrogation, DVF gate, mode selection).

Checkpoint:

If --yes: proceed automatically.

Otherwise, use AskUserQuestion:

• Question: "Product review complete. Continue to planning?"
• Options: "Continue to planning" (recommended) / "Stop here — need to rethink"

If user stops: output "Pipeline stopped after product review. Re-run /deep-plan when ready." Then STOP.

Phase 2: Design Exploration (opt-in)

If --yes: skip this phase (default = skip for opt-in).

Otherwise, use AskUserQuestion:

• Question: "Explore 3-5 different UI directions before writing the spec? Recommended for UI-heavy features."
• Options: "Yes, explore directions" / "No, go straight to spec" (recommended)

If yes: Run /design-shotgun via Skill tool with $FEATURE as arguments. Wait for completion.

If no: Proceed.

Phase 3: Spec (always)

Run /spec via Skill tool with $FEATURE as arguments.

/spec runs Phase 2.5 (lightweight eng + design review) inline and writes a plan file to docs/plans/. Wait for completion.

After /spec finishes, identify the plan file path. Store as $PLAN_PATH:

ls -t docs/plans/*.md 2>/dev/null | head -1

Checkpoint:

If --yes: proceed to Phase 4 (unless --skip-reviews, then jump to Phase 7).

Otherwise, use AskUserQuestion:

• Question: "Spec written to $PLAN_PATH. Phase 2.5 ran inline eng + design checks. What next?"
• Options: "Continue to deep reviews" (recommended) / "Skip reviews, go to decompose" / "Stop here — spec is the deliverable"

If "Skip reviews": jump to Phase 7. If "Stop here": jump to Pipeline Summary.

Phase 4: Engineering Review (opt-out)

If --skip-reviews: skip to Phase 7.

If --yes: run automatically.

Otherwise, use AskUserQuestion:

• Question: "Run deep engineering review? Full interactive review of architecture, code quality, tests, and performance — goes beyond Phase 2.5."
• Options: "Continue (recommended)" / "Skip"

If continue: Run /plan-eng-review via Skill tool with $PLAN_PATH as arguments.

If skip: Proceed.

Phase 5: Design Review (opt-out)

If --skip-reviews: skip to Phase 7.

If --yes: run automatically.

Otherwise, use AskUserQuestion:

• Question: "Run deep design review? Scores 7 UI/UX dimensions 0-10 and fixes the plan."
• Options: "Continue (recommended)" / "Skip"

If continue: Run /plan-design-review via Skill tool with $PLAN_PATH as arguments.

If skip: Proceed.

Phase 6: Multi-Review on Plan (opt-out)

If --skip-reviews: skip to Phase 7.

If --yes: run automatically.

Otherwise, use AskUserQuestion:

• Question: "Run specialized reviewers (security, performance, architecture) on the plan? Catches issues before code is written."
• Options: "Continue (recommended)" / "Skip"

If continue: Run /multi-review via Skill tool with --plan $PLAN_PATH as arguments.

If skip: Proceed.

Phase 7: Decompose (opt-out)

If --no-decompose: skip to Pipeline Summary.

Check if Linear MCP is available (try calling list_teams). If unavailable, skip silently. Log: "Linear MCP not available — skipping decomposition."

Check if /spec already decomposed during Phase 3 (look for Linear issues associated with the plan). If already decomposed, skip.

If --yes: run decomposition automatically.

Otherwise, use AskUserQuestion:

• Question: "Decompose the plan into Linear issues for tracking and dispatch?"
• Options: "Yes, create issues (recommended)" / "No, plan file is sufficient"

If yes: Run /spec via Skill tool with $PLAN_PATH as arguments. Spec will detect the existing plan and offer decomposition.

If no: Proceed.

Rules

• NEVER duplicate sub-skill content. This skill sequences, it does not replace.
• ALWAYS pass $FEATURE or $PLAN_PATH to sub-skills so they have context.
• NEVER skip Phase 1 (product review) or Phase 3 (spec). They are the backbone. If you don't want product review, use /spec directly.
• Each sub-skill handles its own internal interaction (questions, modes, outputs). This skill only manages transitions between them.
• If a sub-skill fails or the user exits it early, stop the pipeline. Do not silently continue.
