Rotifer Self Evolving Agent

Your Agent gets stronger by competing, not by configuring. Scan capabilities, benchmark against Arena rankings, and upgrade to fitter alternatives — driven by objective performance data, not opinions.

Quick Start

Evolve Your Agent

Scan your Agent's current setup and get upgrade recommendations:

/evolve

This analyzes your local Agent configuration, identifies capabilities below Arena median, and recommends higher-performing replacements.

Check Agent Status

View your Agent's capability dashboard:

/evolve status

Shows all installed capabilities, their fitness scores, and overall Agent health.

Upgrade a Capability

Replace a capability with a stronger alternative:

/evolve upgrade <name>

Finds the top-ranked alternative in the same domain and installs it.

Discovery & Comparison

Discover Capabilities

Find capabilities by what you need, not by internal names:

/evolve discover web scraping
/evolve discover --domain code.format
/evolve discover --fidelity Native

Compare Candidates

Side-by-side fitness comparison:

/evolve compare <id-1> <id-2>

Arena Rankings

See top performers in any domain:

/evolve arena search.web
/evolve arena code.format

Inspect Details

Full technical details for a specific capability:

/evolve inspect <id>

Agent Management

Create a New Agent

/evolve create-agent <name>

Run Your Agent

/evolve run-agent <name>

How it Works

Under the hood, Rotifer uses Genes — atomic, transferable AI capabilities that compete in an Arena. The fittest Genes (measured by the fitness function F(g)) survive and are automatically selected.

F(g) = [S_r · ln(1 + C_util) · (1 + R_rob)] / [L · Resource_Cost]

No voting, no human preference — pure runtime performance metrics determine which capabilities win.

Capability Types (Fidelity)

What "Evolve" Actually Does

When you run /evolve, the assistant:

1. Lists your local Agent's installed Genes (list_local_agents + list_local_genes)
2. Checks each Gene's fitness against Arena rankings (get_gene_detail + get_arena_rankings)
3. Identifies Genes scoring below the domain median
4. Searches for stronger alternatives (search_genes)
5. Presents a ranked upgrade plan with fitness comparisons

No Gene is replaced without your confirmation.

Security & Transparency

Runtime dependency

This Skill runs @rotifer/mcp-server@0.8.1 via npx at runtime. The package is fetched from npm on first use and cached locally. This is a standard MCP Skill pattern but means you are trusting remote code — review the source before use.

• Source code: github.com/rotifer-protocol/rotifer-mcp-server
• Verify: npm view @rotifer/mcp-server@0.8.1 dist.integrity

Network requests

All API calls go to the Rotifer public API at rotifer.dev (hosted on Supabase). The MCP server is designed to contact only this endpoint. You can verify by capturing network traffic on first use.

Credentials

The MCP server uses only the Supabase anon key (a public, client-safe key protected by Row Level Security). It does not request, store, or transmit any user secrets, API tokens, or environment variables.

Local data access

• Reads your local Agent configuration (~/.rotifer/) to generate upgrade recommendations.
• Local configuration is designed not to be transmitted to any server. Comparison logic runs locally against data fetched from the public API. You can verify this by inspecting the source code.
• Write operations (install_gene) only modify files under ~/.rotifer/ and require explicit user confirmation — no Gene is replaced silently.

Permission justification

• network:outbound — required to query Arena rankings, Gene metadata, and fitness scores from the Rotifer public API.
