sequential-thinking-skill

Sequential thinking for Claude Code — no MCP server required.
Branch. Revise. Adapt. Think deeper.

Quick Start · Features · How It Works · MCP vs sequential-thinking-skill

A **Claude Code skill** that replicates the [Sequential Thinking MCP server](https://github.com/modelcontextprotocol/servers/tree/main/src/sequentialthinking) with full feature parity. No MCP infrastructure needed — just copy a folder and go.

Claude gains structured, multi-step reasoning with **branching**, **revision**, and **dynamic depth adjustment**, all tracked by a lightweight TypeScript state machine that persists to disk.

Demo

Here's what structured thinking looks like in action:

💭 Thought 1/5
First, I need to clarify what type of auction we're dealing with.
I'll assume sealed-bid first-price unless told otherwise.
[1/5] history=1 next=true

🔄 Revision 3/5 (revising thought 1)
Wait — I assumed one format, but the question is generic.
I should cover multiple auction types. Changing approach.
[3/5] history=3 next=true

🌿 Branch 4/7 (from thought 2, ID: vickrey)
In a Vickrey auction, the dominant strategy is to bid your true
valuation regardless of the number of players. Exploring this path.
[4/7] history=4 branches=vickrey next=true

Each thought is a deliberate step — Claude can **revise** when assumptions ar
