Ruivalim/decision-router

Route each prompt to the right LLM with calibrated Jev decisions.

Automated README summary

Automatically summarized from the README on 6 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

decision-router picks which of your candidate LLMs should handle a prompt, so cheap models take simple edits and strong models take hard debugging. It ships as a CLI, a Claude Code plugin, and a Pi extension for coding agents.

How it uses Jev

One Jev call asks a Choice over candidate models in both orders and a complexity Score from 0 to 4. Plain code averages the Choices, uses the Score as a minimum tier floor, falls back below minConfidence, and filters candidates by context window and quota.

Primitives:choicescore

Technique worth stealing

Ask the same Choice in both orders and average, since Jev leans toward the first option.

Try it

npm install -g decision-router, then decision-router auth set and decision-router pick "...".

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.
