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:
/evolveThis 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 statusShows 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 NativeCompare 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.formatInspect Details

/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)
| Type | Description |
|---|---|
| Native | Pure WASM — fully sandboxed, highest security |
| Hybrid | WASM logic + controlled external calls |
| Wrapped | Thin envelope around an external API |
What "Evolve" Actually Does
When you run /evolve, the assistant:
- Lists your local Agent's installed Genes (
list_local_agents+list_local_genes) - Checks each Gene's fitness against Arena rankings (
get_gene_detail+get_arena_rankings) - Identifies Genes scoring below the domain median
- Searches for stronger alternatives (
search_genes) - 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.
