Browser & OS Action E0 · catalogued

Jev MCP server: a decision layer for coding agents, built on TypeSafe Jev (System One model). Ship gates, risk checks, file triage that keeps files out of context, and a safe headless browser, with calibrated confidence. For Claude Code, Codex, Cursor.

alphaoptimizer

alpha-tales

650

Context GC & Filter MIT E2 · source reviewed

AlphaOptimizer is an open-source tool from AlphaTales that helps Codex work with large command and tool outputs. Instead of sending a huge log or search result straight into the context window, AlphaOptimizer keeps the useful parts visible, keeps the original output available for a limited time, and uses Jev to help rank what matters when an API key is configured.

JEV · Decision point

Jev independently judges relevance for a bounded set of normal output chunks after local bypass and sensitivity rules; the provider validates candidate IDs, sharing budget and exact answer coverage.

Allows a compact visible result while preserving supported originals locally; reported payload reductions are not actual billing savings.

Curates Codex handoff context by using Jev to select old tool records while retaining selected text verbatim.

JEV · Decision point

Judges relevance of eligible read-only tool records; local rules protect required content and assemble a handoff packet.

Preserves source references, selection reasons, and original text order in the handoff.

Browser & OS Action E1 · source linked

The [experimental open-task paths](docs/OPEN_TASKS.md) separate model planning from Jev's typed action selection. They discover browser DOM elements or Windows UI Automation controls dynamically and offer grounded structured-tool / physical-GUI alternatives without a site- or app-specific click sequence. A twelve-action browser-to-VS-Code research case now runs end to end with a model and Jev, but **arbitrary-task generalization is not claimed**.

Context GC & Filter E2 · source reviewed

Verdict-based context compaction for DeepSeek Harness — replaces lossy LLM summaries with fast keep/truncate/drop decisions from jev-latest; everything kept stays verbatim. Port of tamaratran/fast-jev-compaction.

JEV · Decision point

Two Nouls per eligible tool pair control keep, truncate-result or drop-pair. DSH code rebuilds the retained text inside a transcript checkpoint and falls back to compaction-basic on failure.

Keeps selected tool evidence verbatim at DSH’s compaction seam, with an inspectable verdict report and explicit fallback.
