YYLO system / three open-source layers

Coordinate, remember, and evaluate agentic engineering work.

YYLO is one connected system: a control plane for action, a Git-native Ledger for task truth, and Benchmark evidence for comparing agent attempts over time.

Control plane

YYLO

Coordinate bounded agent execution, provenance, validation, review, and integration.

Engineering memory

YYLO Ledger

Preserve Git-native tasks, wiki knowledge, workflow definitions, artifacts, dependencies and history.

0.4.0 stable →

Evaluation evidence

YYLO Benchmark

Compare reviewed cases and independent attempts with later evaluations and separate result rows; frozen checklists make assessment criteria explicit.

0.2.1 stable →

Ecosystem package

YYLO Skills

Reusable procedures for Ledger Records, planning and bounded delivery. Supports all three systems.

2.1.1 stable →

Ecosystem package / independently versioned

Give agents reusable YYLO procedures.
