High-Frequency & Simulation MIT E2 · source reviewed

An island-airport simulator using Jev for routes, yielding, emergency broadcasts and landing order.

JEV · Decision point

Turns aircraft and nearby traffic state into questions whose answers drive simulated actions.

Shows requests, answers and simulation state, with a separate mock path available.

Security & Guardrails E1 · source linked

The signal result above was challenged on three points: no non-AI baseline, selection and evaluation on the same emails, and no equivalent decomposition for the LLM. Three controls were added (`bench/heuristics.py`, `bench/protocol.py`, `run_llm_signals.py`); nothing above was changed. Full tables in `results/report.md`, chart in `results/controls.png`.

JEV · Decision point

Jev returns a structured decision for the local program; consult the source for the exact decision policy.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.

Ranks Claude Code skills for the current project to reduce the descriptions loaded by default.

JEV · Decision point

Assesses skills against the project stack, directory, and README before adjusting description visibility.

Keeps relevant descriptions while preserving manual access to other skills.

Voice & Conversation MIT E2 · source reviewed

A terminal Q&A app where OpenAI writes answers and Jev sets response policy and reviews drafts.

JEV · Decision point

Judges response mode, depth, uncertainty and draft quality inside a LangGraph workflow.

Displays the answer alongside a structured decision report.

Security & Guardrails E2 · source reviewed

Adds tool-call approval and tool-list pruning to the Vercel AI SDK.

JEV · Decision point

Deterministic rules run first; Jev assesses remaining call risks and tool relevance for threshold-based handling.

Approval-call failures request human review; model judgments cannot guarantee detection of every risk.

Decision Tools MIT E2 · source reviewed

A Neovim plugin that asks a plain-language question of every function in the buffer and lists every Jev hit in quickfix, ranked by probability.

JEV · Decision point

Scores each Treesitter function against the user question, splitting across requests if the buffer does not fit. Every hit is listed in quickfix; only hits at or above the threshold get buffer marks.

Finds cross-language shapes that grep misses, and lands the ranked hits in the existing quickfix loop.
