Creative Tools MIT E1 · source linked

Custom nodes for using Jev's text interpretation and judgments in ComfyUI. Use natural-language instructions to select candidates, evaluate conditions, score text, or extract numbers, then pass the results to other nodes. Jev judgments use the TypeSafe API by default.

Context GC & Filter MIT E2 · source reviewed

A pre-compaction advisor for DeepSeek Harness that scores eligible tool results before normal compaction and replaces selected model-visible results with markers or archive pointers.

JEV · Decision point

Jev returns a global should_reduce Noul and per-result retain Nouls; deterministic code keeps protected or invalid items and applies hard-low-retain and dual-signal truncation rules.

Makes pruning incremental and distinguishes recoverable workspace archives from unload-and-rerun behavior.

High-Frequency & Simulation E2 · source reviewed

A ViZDoom Agent that uses Jev to choose movement, targets and firing from structured game state.

JEV · Decision point

Jev selects tactical goals and actions while local geometry handles fine aiming.

Separates game ticks from network inference so the engine need not wait on every frame.

JEV · Decision point

Assesses past conversation turns with Jev when context limits approach, selecting critical tool outputs and user requirements for retention.

Avoids blanket truncation or lossy re-summarization by selectively preserving exact code locations and decision traces.

Domain & Vertical Tools E1 · source linked

We built a working MVP that pairs an LLM-authored ontology with Jev's calibrated classification, tested it against the live Jev API on 78 unique tickets across 5 sessions (86 classifications -- Session 4 re-runs Session 2's eight tickets), closed the feedback loop, and ran a 3-iteration convergence experiment. Total cost: $0.0085.
