Automated README summary
Automatically summarized from the README on 30 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Harness Router is a framework-agnostic tool router for coding agents. It takes a goal, observation, and available tools, then returns a next-tool choice, confidence, or a planner fallback, keeping obvious calls on a fast path.
How it uses Jev
Jev makes discrete next-tool decisions from compact state and tool descriptions via OpenRouter. The router accepts choices above a confidence threshold, caches reusable high-confidence choices, and otherwise falls back to the host planner. MCTS can optionally use a Jev prior.
Primitives:choice
Technique worth stealing
Route only genuinely ambiguous tool choices through Jev; keep obvious calls on a fast path and fall back to the planner on low confidence.
Try it
uv tool install --force --with 'mcp>=2' harness-router, then run har route --help.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
