YYLO
A command-line orchestrator that runs coding agents through a typed task lifecycle with isolated worktrees, validation gates, and Git-protected merges.
Profile
Where it fits
YYLO is an MIT-licensed command-line orchestrator for coding agents, repeatable workflows, and receipt-backed repository changes. It installs from npm as @yylo/cli and exposes equivalent yylo and yy launchers.
task start freezes the protected target SHA, creates a dedicated branch and worktree, and completes configured dependency hydration before reporting WORKING; implementation and focused tests happen in that worktree, task finish verifies delivery, and merge land composes the change in a detached candidate using Git expected-old ref protection.
Task and Kanban state, Record storage, and evaluation evidence live in the separate YYLO Ledger and YYLO Benchmark packages; yy ledger and yy benchmark delegate to those independently installed CLIs rather than bundling alternate implementations.
Builder web analytics
Measure outcomes from YYLO-orchestrated work
YYLO records task runs, receipts, and merge results. Separately configured analytics can help a team assess a deployed change's user-facing results.
This is an optional workflow, not a built-in YYLO integration with Agent Analytics. Configure tracking on the deployed product and analytics access separately; YYLO does not install tracking or send its run receipts to Agent Analytics.
First loop to measure
- a team uses YYLO to run a coding-agent task and land the reviewed change
- the team deploys the change to a separately instrumented surface
- a human or an agent with separately configured analytics access reads the observed results
- the team uses that evidence when deciding on the next task
Copyable prompt
If analytics access and tracking are already configured, inspect the deployed change's observation window and report measured user outcomes. Otherwise, explain what is missing. Do not imply a native YYLO integration or infer causation from a before-and-after comparison alone.
