rtk-engine

The RTK pipeline engine: it parses, resolves and validates pipeline.toml, evaluates rules, and runs the methods and chains those rules name. The rtk CLI links it for the hooks; the rtk-proxy daemon links it for proxy.request rules.

User documentation

The pipeline reference lives in the user guide, docs/guide/pipelines/, published at rtk-ai.app/guide:

Page	Covers
Pipelines	what the engine does, the files you might write, upgrading
Writing a Pipeline	file locations and load order, the rule tree, actions, routing, overrides
Conditions and Judges	every when key, the call context, classifiers
Methods	built-in methods and chains, your own chains and filters
Directives	text RTK puts in front of the agent
Tasks and Upstreams	delegation to a cheaper model
Reference Pipelines	the six built-ins as literal files
Pipeline Commands	show, validate, explain, shadow, share, adopt
