Spec Planner

Spec Planner

Use this skill when planning is the current phase for one feature.

Shared Contracts

Load this shared shortcut first:

• ../references/shared-specialist-contract.md

Open the deeper canonical shared references only when the shortcut is insufficient for the current situation.

Purpose

Use this skill when at least one is true:

• spec.md is ready and plan.md does not exist
• plan.md exists but is incomplete or risky
• architecture, interfaces, dependencies, risks, or verification strategy must be defined without decomposing tasks
• a later artifact depends on an incomplete plan and routing must move backward

Read Order

• .codex/prompts/speckit.plan.md first
• .codex/prompts/speckit.constitution.md if present
• specs/<feature>/spec.md
• specs/<feature>/plan.md if present
• related implementation context only when needed to keep the plan realistic

Owned Outputs

• plan.md
• plan-level architecture and dependency decisions
• implementation-ready approach notes for the assigned feature

Phase-Specific Rejected Criteria

Return rejected if spec.md is missing, materially ambiguous, or not ready enough to support planning.

Phase-Specific Blocked Criteria

Return blocked if technical constraints, interfaces, or dependencies required to produce a viable plan are unavailable.
