  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 79/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 209 tokens (~209/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.

  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 1 captured unit(s) of tool text and found none that tries to manipulate the model reading it.

### `jev_decide` (~209 tokens)

Ask Jev for typed decisions

Evaluate supplied context using TypeSafe Jev. Batch independent, narrow questions in one call: choice selects a provided label; score returns a position on 2–10 ordered levels (0-based); noul returns probability of yes, not intensity. Supply relevant evidence and full instructions; question IDs are not sent to the model. Include an other/none choice when appropriate. Questions cannot use each other's answers. Returns raw judgments, probabilities, confidence for choice/score, and token usage. Use caller-defined policies for uncertainty. This sends the supplied state and questions to TypeSafe and may incur API charges. It does not execute selected actions.

Input parameters:

- `model` (string): Optional TypeSafe model override; defaults to the configured model or jev-latest.
- `questions` (object, required): Named independent questions over the same state. IDs are not model instructions; write each full judgment in instructions.
- `state` (required): Relevant source text or JSON context; include evidence, definitions and policies needed for the questions.

Output parameters:

- `answers` (object)
- `model` (string)
- `usage` (object)
