What is retrieval-augmented-thinking CLAUDE.md?

Instructions for a retrieval-augmented thinking tool named RAT. Retrieval-augmented thinking means using retrieved context while forming, checking, and revising lines of reasoning.

Running structured reasoning steps, testing hypotheses, exploring alternatives, proposing revisions, and marking verification points.

They explain how to install and connect the tool so an agent can preserve context while exploring and checking multiple hypotheses.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01253	$0.01253
Opus 5.5	$0.00501	$0.00501
Sonnet 5.5	$0.00251	$0.00251
Haiku 4.5	$0.00125	$0.00125

Security

Grade A, and why

retrieval-augmented-thinking CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

RAT (Retrieval Augmented Thinking) MCP Tool

Tool Name

rat

Description

A context-aware reasoning system that orchestrates structured thought processes through dynamic trajectories. Implements iterative hypothesis generation and validation cycles while preserving context coherence across non-linear reasoning paths.

Installation

Simple 3-Step Process

git clone https://github.com/stat-guy/retrieval-augmented-thinking.git
cd retrieval-augmented-thinking
npm install -g .

Verify Installation

Test before configuring Claude Desktop:

npx mcp-server-rat-node --help

Success indicator: If you see RAT MCP Server (Node.js) running on stdio, installation is complete!

Claude Desktop Configuration

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "rat": {
      "command": "npx",
      "args": ["mcp-server-rat-node"]
    }
  }
}

Restart Claude Desktop after adding the configuration.

Parameters

Required Parameters

thought (string): Structured reasoning step content
- Primary analysis chains
- Hypothesis formulation/validation
- Branch exploration paths
- Revision proposals
- Context preservation markers
- Verification checkpoints
nextThoughtNeeded (boolean): Signal for continuation of reasoning chain
- true: Continue to next thought
- false: Complete current reasoning trajectory
thoughtNumber (integer, min: 1): Position in current reasoning trajectory
- Sequential numbering starting from 1

branchFromThought (integer): Indicates parallel exploration paths source
branchId (string): Context identifier for parallel reasoning chains
needsMoreThoughts (boolean, default: false): Signals scope expansion requirement

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
