Bidirectional planning for ambiguous or design-heavy tasks. Use when the user requests help breaking down a problem or formulating a plan, and also when an existing plan has too many gaps or needs refinement; converge top-down framing with bottom-up inventory and explicit questions.

Pincer Planning

Overview

Create a plan by pairing a top-down framing with a bottom-up inventory, stress-testing both with questions, then merging into a single, gap-checked plan. Use for design, strategy, or fuzzy scopes.

Quick start

  1. Draft top-down framing (goal, constraints, success criteria).
  2. Draft bottom-up inventory (facts, assets, risks, unknowns).
  3. Ask clarifying questions (use AskUser).
  4. Flip perspective and refine the opposite view.
  5. Merge into a single plan and list remaining gaps.

Core Guidance

  • Start with either top-down or bottom-up; explicitly label the other side as provisional.
  • Ask 3–7 targeted questions that would change the plan, then wait for answers.
  • After answering, re-run the opposite perspective to find contradictions or gaps.
  • Converge: produce a merged plan plus a short gap list (what’s still unknown).
  • Keep planning separate from execution; do not run tools during planning.

Trust / Permissions

  • Always: Read local files, ask clarifying questions, draft plans.
  • Ask: Any writes to disk (e.g., saving plan.json), network calls, or execution.
  • Never: Destructive actions or credential exfiltration.

Resources

  • references/pincer-checklist.md: Question prompts and convergence checks.
  • templates/plan.json: Plan scaffold with top-down and bottom-up sections.

Validation

  • Confirm top-down and bottom-up sections converge; list explicit gaps.
  • Ensure questions are answered before final plan is delivered.
