MCP Skill: Software Planning

Scope

Use the MCP server configured as Software-planning-mcp in .vscode/mcp.json to produce planning artifacts that align with Black-Tortoise governance (DDD boundaries, append-before-publish, minimalism).

Preconditions

• Ensure .vscode/mcp.json contains a server entry named Software-planning-mcp .

• Planning output must be compatible with the repo workflow (requirements/design/tasks + audit notes when needed).

Operating Rules

• Keep plans minimal and verifiable (Occam's Razor): only create artifacts that will be used.

• Tie every plan step to a concrete file/command in this repo (e.g., pnpm run architecture:gate ).

• Do not invent APIs or layers; follow existing module boundaries.

Typical Workflows

• Requirements drafting

• Input: feature goal, constraints, affected bounded context/capability.

• Output: acceptance criteria + non-functional constraints.

• Design outline

• Input: existing module location + eventing/state constraints.

• Output: dependency direction, events, store changes, UI signals, persistence.

• Task breakdown

• Output: ordered tasks with explicit validation steps (lint/build/gate/tests).

Prompt Templates

• "Create a requirements.md and tasks.md plan for: . Constraints: Angular 20 zoneless, signals-first, event-first flow, DDD boundaries. List files to touch and commands to run."

• "Draft a design.md for capability using append-before-publish, include event schema and causality IDs. Keep it minimal."

Validation Checklist

• Architecture direction preserved (Presentation -> Application -> Domain; Infrastructure implements ports).

• Append -> Publish -> React ordering explicit.

• Testing/gates listed when the change touches architecture, eventing, or integration.
