What Evolve does

Evolve starts or monitors an evolutionary development loop that iteratively refines ontology and acceptance criteria across generations until convergence. Use it to evolve a coding task through generation, execution, judgment, and gating with the Ouroboros MCP tools.

Evolve is cataloged under AI Engineering on DirSkills. Evolve comes from a repository tagged agent-os, agentic-ai, ai-agent, ai-coding-agent and claude-code.

Documentation

README

Excerpt

Gen 1: Seed(O₁) → Execute(all nodes) → Judge → Gate
Gen 2: Wonder(failed nodes) → Reflect(active nodes only) → Execute(active) → Gate(all)
Gen 3: Repeat with a smaller active set; frozen PASS nodes are reverified, not regenerated
...until the outcome gate passes, the working set stagnates, ontology converges,
or max 30 generations is reached

Usage

Start a new evolutionary loop

ooo evolve "build a task management CLI"

Fast mode (ontology-only, no execution)

ooo evolve "build a task management CLI" --no-execute

This is the opening of the README. Read the full README on GitHub.

Frequently asked about Evolve

What else does Q00 publish alongside Evolve?
Evolve is one of 25 skills that DirSkills catalogs from Q00/ouroboros, the repository it ships in. Its siblings there include Brownfield, Brownfield and Cancel. Each one is a separate skill with its own page in this directory, installs the same way Evolve does, and is maintained by Q00 in that same repository. The rest of the collection is listed on the Q00/ouroboros page.
How does Evolve compare to other AI Engineering skills?
Evolve ranks #467 by stars among the 2451 AI Engineering skills in this catalog. The most-starred ones next to it are Architecture Decision Records, AI-First Engineering and Agentic OS. DirSkills ranks by the star count of the repository each skill ships in, so that order reflects how popular those repositories are rather than any review of Evolve against them. Open each page to compare what they document and how they install.
