OpenCode plugin that lets Jev pick reasoning effort per step.

Automated README summary

Automatically summarized from the README on 11 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

An OpenCode plugin for developers using wrapped OpenAI or Anthropic models. It asks Jev how much reasoning each primary request needs, so one model handles quick edits and hard debugging without manually switching effort levels.

How it uses Jev

For each primary request, the plugin sends a bounded summary of recent conversation to Jev, which picks a reasoning effort. That choice is added as an OpenAI configuration_update item or an Anthropic effort-only system message. If Jev is slow or unavailable, the request continues at a fallback effort (high by default).

Primitives:choice

Technique worth stealing

Cacheable prompt prefix: earlier effort updates stay in place so the prompt prefix stays cacheable.

Try it

Add the plugin to OpenCode config, export JEV_API_KEY and OPENAI_API_KEY, restart OpenCode.

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.
