/research-and-plan [output FILE] <description...> — Meta-Plan Decomposer

Breaks broad goals into focused sub-plans, each drafted via /draft-plan and executed via /run-plan. The output is a meta-plan file whose phases are pure delegation — no drafting happens during execution.

Ultrathink throughout.

Arguments

• output FILE (optional) — meta-plan output path. Default: plans/<SLUG>_META.md (slug from description).
• auto (optional) — skip the decomposition confirmation checkpoint. Proceed directly to drafting after decomposition research. Used by /research-and-go for fully autonomous operation.
• description (required) — everything after recognized keywords.

Detection: scan arguments for output + path, auto, and first token ending .md. Everything else = description. auto is stripped from the description.

Escalation from /draft-plan: If the invoking context mentions a research file at /tmp/draft-plan-research-*.md, read it — that research feeds Step 1 and avoids redundant exploration.

Step 1 — Decomposition Research

Three focused investigations. If a research file was passed from /draft-plan, start from it — validate and extend rather than starting from scratch.

1a. Domain survey — Dispatch Explore agents to map the scope: what the

goal encompasses, what exists already, natural sub-domains, shared infrastructure needed across sub-problems.

1b. Dependency analysis — Build a dependency graph: which sub-problems

are independent (parallelizable), which are sequential, and whether shared prerequisites exist (e.g., "generalize the port system" before new domains).

1c. Scope sizing — Estimate each sub-problem's size. If a sub-plan

would need 8+ phases, split further. Each must be completable by /run-plan finish auto in one session. Mark in-scope vs. out-of-scope.

Present the decomposition:

Decomposition complete. I identified N sub-problems:

1. Sub-problem A — [one-line description] (est. N phases)
2. Sub-problem B — [one-line description] (est. M phases, depends on A) ...

Dependency graph: A -> B -> D, A -> C (independent of B)

In scope: [list]. Out of scope: [list].

Without auto: wait for user confirmation. They may reorder, drop, merge, or add sub-problems. Do NOT proceed until confirmed.

With auto: present the decomposition for the record, then proceed directly to Step 2. The user said auto — that's approval.

Step 2 — Draft All Sub-Plans

After user approval, draft each sub-plan by invoking /draft-plan.

DO NOT just skip /draft-plan and issue agents to plan directly. If you do, all work will be thrown out. /draft-plan dispatches separate reviewer and devil's advocate agents that catch problems you cannot catch in your own work. Writing a plan and self-reviewing it is not adversarial review — it's rubber-stamping.

PROHIBITED — the exact shortcut that keeps failing: Do NOT use the Agent tool to dispatch "plan-drafting agents" or "writing agents" that produce plan files directly. The ONLY way to draft a sub-plan is via the Skill tool with skill: "draft-plan". This has been violated three separate times, each time producing garbage that was thrown out. The agent rationalizes "I'll go faster" and skips adversarial review. It does NOT go faster — it produces plans with 10+ CRITICAL issues that require full restarts.

For each sub-problem:

1. Determine the sub-plan output path: plans/<SLUG>_<N>.md (or let the user specify).
2. If research from Step 1 was written to a file, pass that path to the /draft-plan agent so it has the decomposition context.
3. Dispatch: /draft-plan output <path> <sub-problem description>
4. Wait for each /draft-plan batch to complete before dispatching the next batch (see parallelism rules below).

Parallelism and resource limits: Dispatch at most 3 /draft-plan agents concurrently. Wait for each batch to complete before the next. While waiting, do NOT draft plans yourself — wait. The idle time is the cost of not melting the container. Past failure: 11 parallel agents caused load average 67, 54 test timeouts, and forced a full restart.

Draft in dependency order:

1. Foundation plan first (alone — everything depends on it)
2. Independent plans in batches of 3
3. Dependent plans after their prerequisites complete

Dependent sub-plans must be drafted after their prerequisites so later plans can reference earlier plans' actual content.

Staleness notes for dependent sub-plans. Sub-plans that depend on earlier ones get this in their Dependencies section:

### Dependencies
- Plan A must be complete. **Note:** This plan was drafted before Plan A
  was implemented. APIs and data structures referenced here are based on
  Plan A's design, not actual code. `/run-plan` may refresh this plan
  before execution.

This tells /run-plan to offer a plan refresh (interactive) or auto-refresh (auto mode) before implementing — ensuring the plan reflects actual code, not predictions.

Step 2b — Verify All Sub-Plans Were Properly Drafted

Before proceeding to cross-plan review, verify that each sub-plan went through /draft-plan's adversarial process. Two checks:

Check 1 — Mechanical (grep)

for plan in plans/<SLUG>_*.md; do
  if ! grep -q '## Plan Quality' "$plan" || ! grep -q '### Round History' "$plan"; then
    echo "FAILED: $plan — missing adversarial review signature"
  fi
done

If any plan fails, it was not drafted via /draft-plan. Stop and re-draft it properly.

Check 2 — Verification agent

Dispatch a verification agent that reads every sub-plan file and checks:

1. ## Plan Quality section exists with ### Round History table
2. Round History has at least one round with non-zero findings — real adversarial review almost always finds issues on round 1. A table showing "0 issues | 0 issues" on round 1 is suspicious.
3. The findings described in Round History reference specific content from the plan (phase names, field names, design decisions) — not generic boilerplate like "looks good, no issues found"
4. The plan's phases have concrete work items and acceptance criteria — not vague descriptions that suggest a rushed draft

The agent reports pass/fail per plan with evidence. Any plan that fails must be re-drafted via /draft-plan before proceeding.

Do NOT proceed to Step 3 with unreviewed plans — the cross-plan review cannot compensate for plans that were never individually reviewed.

Step 3 — Cross-Plan Consistency Review (converge until clean)

After all sub-plans are drafted and verified (Step 2b), review the full set for cross-plan consistency. Individual sub-plans were reviewed by /draft-plan, but cross-plan issues (shared schemas, naming collisions, directory conflicts, storage model disagreements) only emerge when you look at all plans together.

Each round: dispatch 2+ review agents in parallel

Reviewer agent — cross-plan consistency:

• Do all sub-plans agree on shared data structures, schemas, field names?
• Are directory paths, ID prefixes, and namespaces consistent?
• Is the dependency ordering correct?
• Are there missing sub-problems? (Infrastructure, integration, glue?)

Devil's advocate agent — structural risks:

• Wrong split — would a different decomposition be simpler?
• Hidden coupling — shared assumptions that break if one plan changes?
• Missing glue — who integrates the sub-plans?
• Deferred complexity — hardest part buried in the last sub-plan?

After each round: apply fixes to the sub-plan files

This is the critical step that was previously missing. For every finding that changes a sub-plan's assumptions, schemas, naming, or structure — edit the actual sub-plan file. Do NOT just document resolutions in the meta-plan. The sub-plan files are what /run-plan reads; the meta-plan is an index, not a patch set.

Verify each fix was applied by reading the sub-plan file after editing.

Convergence

Continue rounds until no CRITICAL or MAJOR issues are found. Minor issues may be noted for implementation-time resolution. Maximum 3 rounds — if still finding MAJOR issues after 3 rounds, the decomposition itself may need restructuring. Report to the user.

Step 4 — Write the Meta-Plan

After all sub-plans are drafted and the decomposition is reviewed, write the meta-plan. Every phase is pure delegation — /run-plan executes sub-plans, no /draft-plan during execution.

Meta-plan template

# Meta-Plan: <Title>

## Overview
[What this meta-plan accomplishes and the decomposition rationale]

## Decomposition
[Sub-problems identified, dependency graph, scope rationale]

## Sub-Plans
| Plan | Phases | Dependencies | Notes |
|------|--------|--------------|-------|
| [SUB_PLAN_A.md](SUB_PLAN_A.md) | N | None | |
| [SUB_PLAN_B.md](SUB_PLAN_B.md) | M | A | May need refresh after A |

## Progress Tracker
| Phase | Status | Commit | Notes |
|-------|--------|--------|-------|
| 1 — Implement: <sub-problem A> | ⬚ | | |
| 2 — Implement: <sub-problem B> | ⬚ | | |

## Phase N — Implement: <Sub-problem X>

### Goal
Execute the plan for <sub-problem X>.

### Execution: delegate /run-plan plans/<SUB_PLAN_X>.md finish auto

### Acceptance Criteria
- [ ] All phases in the sub-plan are marked Done
- [ ] All tests pass on main after landing
- [ ] Plan report exists with verification results

### Dependencies
[List prerequisite phases. Dependent sub-plans may auto-refresh.]

## Plan Quality
**Drafting process:** /research-and-plan with cross-plan consistency review
**Sub-plans:** Each drafted via /draft-plan with adversarial review
**Cross-plan review:** N rounds until no CRITICAL/MAJOR issues remain

Repeat the Phase N template for each sub-problem. First phase has Dependencies: None. Dependent phases list their prerequisites and note that the sub-plan may auto-refresh to reflect actual implementation.

Tracking — Standalone Invocation

If this skill was invoked directly (not via /research-and-go), create tracking requirement files so that pipeline-aware tools can monitor progress. This only applies when /research-and-go did not already create them.

After writing the meta-plan, check for an existing pipeline sentinel:

MAIN_ROOT=$(cd "$(git rev-parse --git-common-dir)/.." && pwd)

If $MAIN_ROOT/.claude/tracking/pipeline.active does not exist, this is a standalone invocation. Create requirement files for each phase that delegates to /run-plan:

mkdir -p "$MAIN_ROOT/.claude/tracking"
for i in 1 2 ... N; do
  printf 'skill=run-plan\nindex=%d\nrequiredBy=research-and-plan\ncreatedAt=%s\n' "$i" "$(date -Iseconds)" > "$MAIN_ROOT/.claude/tracking/requires.run-plan.$i"
done

Replace 1 2 ... N with the actual phase indices from the meta-plan (one per phase that uses delegate /run-plan). These files allow a subsequent /run-plan invocation (or a monitoring tool) to know how many phases the meta-plan expects and track which have been completed.

If pipeline.active does exist, /research-and-go already created the requirement files in its Step 1b — do not create duplicates.

Note: The existing 3-layer /draft-plan verification (Step 2b) is fully preserved. Tracking supplements the verification process; it does not replace it.

Finalization

1. Write the meta-plan to the output path.
2. Update plans/PLAN_INDEX.md if it exists (add a row to "Ready to Run"). If it doesn't exist, suggest /plans rebuild.
3. Present the result:

   Meta-plan written to plans/<FILE>.md with N sub-plans. Sub-plans: [list with paths]

   Execute with: /run-plan plans/<FILE>.md Or with scheduling: /run-plan plans/<FILE>.md auto every 4h now

Key Rules

• Pure delegation in the meta-plan. Every phase uses ### Execution: delegate /run-plan. No delegate /draft-plan — all drafting happens upfront in Step 2.
• User confirms the decomposition. Step 1 ends with a checkpoint. Do not draft sub-plans until the user approves the split.
• Staleness notes on dependent sub-plans. Sub-plans drafted before their dependencies are implemented get explicit warnings so /run-plan knows to refresh.
• Adversarial review targets the decomposition. Individual sub-plans get their own review via /draft-plan. Step 3 reviews the split itself.
• Respect constraints. No external solvers, no bundlers, no dependencies without approval. These apply to every sub-plan.
• Each sub-plan must be session-completable. If a sub-plan needs 8+ phases, split it further.
