description	Strategic planning — create implementation plan from brainstorm specs. Tasks, dependencies, acceptance criteria.

Planning From Specs

Turn brainstorm decisions into an actionable implementation plan.

Boundaries

This skill MAY: read specs, read codebase, ask questions, write plan document, update brainstorm checkboxes. This skill MAY NOT: edit code, implement anything, run tests, deploy.

NEVER write code during this skill. This is planning, not implementation.

Command Format

/unipi:plan specs:<path>(multiple,optional) <string(greedy)>(optional)

• specs:<path> — one or more brainstorm specs to plan from (auto-suggested)
• string(greedy) — optional scope guidance (e.g., "focus on API layer only")
• If no specs provided → agent asks user which spec to plan from
• Runs in current session, read-only sandbox + write to .unipi/docs/

Sandbox

• Read: full codebase access for context
• Write: only .unipi/docs/ directory

Output Path

.unipi/docs/plans/YYYY-MM-DD-<topic>-plan.md

Committed to current branch.

---

Phase 1: Load Specs

1. If specs: arg provided, read those spec files
2. If not provided, list available specs in .unipi/docs/specs/ and ask user to choose
3. Read the spec(s) fully — understand problem, approach, design, checklist

Exit: Spec(s) loaded. Understand what to plan.

---

Phase 2: Review & Ask

1. Review spec critically — identify concerns or gaps
2. If concerns: raise with user before proceeding
3. If string(greedy) provided: use it to scope planning (e.g., "focus on auth only")
4. Ask clarifying questions if needed (one at a time)
5. Ask about work branch:

"Where should this work happen?"

1. Main branch — work directly on main (small/medium tasks, low risk)
2. New branch — isolated worktree (larger tasks, risky changes)

If "New branch": "What branch name? (e.g., feat/auth, or press enter for auto-naming based on spec topic)"

Record the decision:

• Main branch → workbranch: will be empty in plan frontmatter
• New branch → workbranch: {branch-name} in plan frontmatter (auto-generate feat/{topic} if not provided)

Exit: No blockers. Branch strategy decided. Ready to plan.

Phase 3: Create Implementation Plan

Structure the plan with heart of gold style:

---
title: "{Topic} — Implementation Plan"
type: plan
date: YYYY-MM-DD
workbranch: {branch-name}   # empty string = work on main branch
specs:
  - path/to/spec.md
---

# {Topic} — Implementation Plan

## Overview
{Brief summary of what this plan covers}

## Tasks

- unstarted: Task 1 — {Task Name}
  - Description: {What needs to be done}
  - Dependencies: {None, or list of tasks}
  - Acceptance Criteria: {How to verify done}
  - Steps:
    1. {Concrete step}
    2. {Concrete step}

- unstarted: Task 2 — {Task Name}
  - Description: ...
  - Dependencies: ...
  - Acceptance Criteria: ...
  - Steps: ...

## Sequencing
{Order of execution, dependency graph if complex}

## Risks
{Potential blockers or concerns}

Task Guidelines

• Each task should be discrete and completable in one session
• Dependencies must be explicit — task B can't start before task A
• Acceptance criteria must be verifiable — not "looks good" but "tests pass, builds clean"
• Steps are bite-sized — agent can follow without guessing
• Order tasks by dependency (foundational work first)

Task Status Lifecycle

Tasks use prefixes to track progress:

Status	Meaning
unstarted:	Not started
in-progress:	Being worked on
completed:	Done and verified
failed:	Attempted but failed, needs investigation
awaiting_user:	Needs user action (test, approve, provide input)
blocked:	Waiting on dependency or external factor
skipped:	Intentionally not doing (deferred, out of scope)

---

Phase 4: Update Brainstorm Checkboxes

After plan is complete:

1. Read the source brainstorm spec(s)
2. For each checklist item covered by this plan, mark [x]
3. Leave items not covered as [ ]
4. Write updated spec back

Example:

## Implementation Checklist
- [x] Set up auth middleware — covered in Task 1
- [x] Create login endpoint — covered in Task 2
- [ ] Add OAuth support — deferred to next plan
- [ ] Rate limiting — out of scope

This creates the link between brainstorm and plan — plan covers some items, others remain for future plans.

Semantics: Spec [x] means "planned" (covered by a plan). It does NOT mean "done". Implementation progress is tracked in the plan file, not the spec.

---

Phase 5: Review Plan

Self-check before presenting:

• Every task has clear acceptance criteria
• Dependencies are correct (no circular, no missing)
• Steps are bite-sized (agent can follow without guessing)
• String greedy scope respected (if provided)
• Plan is focused enough for single /unipi:work session

Do NOT re-read or re-edit the spec checkboxes — Phase 4 already wrote them.

---

Phase 6: Present & Handoff

Present plan summary to user. Then ask what to do next. If ask_user is available, prefer structured handoff options using action: "new_session" so the selected workflow can be queued automatically:

ask_user({
  question: "What would you like to do next?",
  options: [
    {
      label: "Proceed to /unipi:work",
      description: "Start implementing the plan",
      value: "work",
      action: "new_session",
      prefill: "<work-command>",
    },
    {
      label: "Proceed to /unipi:auto",
      description: "Run full pipeline (work → review → merge)",
      value: "auto",
      action: "new_session",
      prefill: "/unipi:auto plan:YYYY-MM-DD-<topic>-plan.md",
    },
    { label: "Revise plan", description: "Adjust tasks or scope", value: "revise" },
    { label: "Done for now", description: "Return later", value: "done", action: "end_turn" },
  ],
  allowFreeform: false,
})

Use the correct <work-command>:

• Worktree branch → /unipi:work worktree:<branch-name> specs:YYYY-MM-DD-<topic>-plan
• Main branch → /unipi:work specs:YYYY-MM-DD-<topic>-plan (no worktree arg)

Copyable fallback commands when ask_user is unavailable:

/unipi:work worktree:<branch-name> specs:YYYY-MM-DD-<topic>-plan
/unipi:work specs:YYYY-MM-DD-<topic>-plan
/unipi:auto plan:YYYY-MM-DD-<topic>-plan.md

Recommend starting a new session for work if using a worktree; the ask_user launcher handles compact/direct queuing when available.

Resumability

If user runs /unipi:plan on an existing plan:

1. Read the plan — look for completed: tasks
2. Ask user if they want to add tasks, modify existing, or plan new scope
