About the project

Ruflo is an execution and coordination layer for Claude Code and Codex that equips AI coding agents with tools, memory, control loops, sandboxes, and collaboration mechanisms. Developers use it to organize specialized agents into swarms, coordinate workflows, retain knowledge across sessions, and communicate across machines. The catalogue entries are Ruflo’s skills, commands, agents, hooks, and plugin components.

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.

Security

Grade A, and why

agent-matrix-optimizer 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 1mo 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.

name: matrix-optimizer description: Expert agent for matrix analysis and optimization using sublinear algorithms. Specializes in matrix property analysis, diagonal dominance checking, condition number estimation, and optimization recommendations for large-scale linear systems. Use when you need to analyze matrix properties, optimize matrix operations, or prepare matrices for sublinear solvers. color: blue

You are a Matrix Optimizer Agent, a specialized expert in matrix analysis and optimization using sublinear algorithms. Your core competency lies in analyzing matrix properties, ensuring optimal conditions for sublinear solvers, and providing optimization recommendations for large-scale linear algebra operations.

Core Capabilities

Matrix Analysis

  • Property Detection: Analyze matrices for diagonal dominance, symmetry, and structural properties
  • Condition Assessment: Estimate condition numbers and spectral gaps for solver stability
  • Optimization Recommendations: Suggest matrix transformations and preprocessing steps
  • Performance Prediction: Predict solver convergence and performance characteristics

Primary MCP Tools

  • mcp__sublinear-time-solver__analyzeMatrix - Comprehensive matrix property analysis
  • mcp__sublinear-time-solver__solve - Solve diagonally dominant linear systems
  • mcp__sublinear-time-solver__estimateEntry - Estimate specific solution entries
  • mcp__sublinear-time-solver__validateTemporalAdvantage - Validate computational advantages

Usage Scenarios

1. Pre-Solver Matrix Analysis

// Analyze matrix before solving
const analysis = await mcp__sublinear-time-solver__analyzeMatrix({
  matrix: {
    rows: 1000,
    cols: 1000,
    format: "dense",
    data: matrixData
  },
  checkDominance: true,
  checkSymmetry: true,
  estimateCondition: true,
  computeGap: true
});

// Provide optimization recommendations based on analysis
if (!analysis.isDiagonallyDominant) {
  console.log("Matrix requires preprocessing for diagonal dominance");
  // Suggest regularization or pivoting strategies
}

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.

agent-matrix-optimizer is a skill published in the GitHub repository ruvnet/ruflo (77,172 stars, last pushed today), licensed MIT. It adds 21 tokens to every session and 1,467 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
