Agentic Harness — Systemic Agentic Framework.
The agent harness — deterministic resolutions, validations, and traceability of agentic workflows, keeping probabilistic agents on rails.
Why it matters
What Agentic Harness changes for you.
The workflow step graphs are validated by a deterministic harness — methodology- and host-agnostic, so the same method runs unchanged on any agent host, and work state lives in your own files and git history.
Deterministic rails for probabilistic agents.
Every step passes precondition, authorization, and postcondition checks grounded in persisted configuration — agents advance through evidence and sequence, not vibes.
Delivered by Workflow & step resolution · Agent authorization
Invalid bytes never land.
Agents stage writes in the working tree; the harness validates artifacts against their schemas before commit — invalid output is discarded and restored, so committed state is always clean.
Delivered by Artifact validation
One method, any host.
The harness is a stable CLI over plain files — the same workflows run in your IDE today and a CI runner tomorrow, with no relearning and no lock-in.

Features
What Agentic Harness does.
Workflow & step resolution
Workflow and step graphs are resolved deterministically from plain files — the same method runs unchanged on any agent host.
Skill and instruction prompt injection
Skills and instructions are injected into the agent’s context at the right step — knowledge arrives exactly when it’s needed.
LLM resolution
The harness resolves which model backs each step — swappable, host-agnostic, no hard-wired vendor lock-in.
Artifact validation
Every artifact produced by a step is validated against its schema before the step is considered complete.
Agent authorization
Pre, invariant, and post conditions gate every step — agents move through evidence and sequence, not vibes.
Logging
Every step execution is journaled — the delivery history is an auditable event log, not a chat scrollback.
