MCP Skill: Sequential Thinking

Scope

Use the MCP server configured as sequentialthinking in .vscode/mcp.json to produce step-by-step reasoning artifacts for complex changes.

Preconditions

• Ensure .vscode/mcp.json contains a server entry named sequentialthinking.

Operating Rules

• Prefer short, ordered steps that can be validated locally.
• Call out unknowns explicitly and convert them into concrete discovery steps (search files, read AGENTS, inspect type errors).
• Keep the solution Occam-simple: avoid introducing new abstractions without a demonstrated need.

When To Use

• Refactors crossing multiple modules (shell/workspace/capability/eventing/integration).
• Any change that might impact DDD boundaries or the append-before-publish contract.
• Debugging nondeterministic behavior (signals/streams, event ordering).

Output Shape

• A numbered sequence of actions.
• Each action includes: target file(s), expected outcome, and how to verify (command or observation).

Prompt Templates

• "Think sequentially about implementing . Identify risks (DDD boundaries, event causality, signals boundary) and produce a minimal step plan with verification per step."
• "Given this error/log: , produce an ordered debug plan with the smallest set of probes/changes."
