# Model Governance and Evaluations

> Control model availability, customize agent eval rubrics, and automate API access through named CLI environments.

## What's New

### Model Availability Controls

Organization and Project administrators can exclude models by model ID, provider, or vendor. Organization rules flow into every Project, and safety checks prevent a policy from removing every active model. See [Model governance](/docs/production/model-governance).

### Custom Agent Eval Rubrics

Agent eval runs can now use a custom objective and ordered rubric. The resolved policy is stored with the run, while evals without a custom policy continue to use functional equivalence. See [Evals](/docs/production/evals).

### Project-Wide Share Management

A unified Shares view brings Task and agent shares into one searchable, filterable list. Share tags can be managed from the same Project-level workflow.

### CLI Access Tokens and Environments

The Rightbrain CLI can return a refreshed access token with its deployment and Project context. JSON environment listings make authenticated API automation independent of the CLI's private credential-file format. See [Rightbrain CLI](/docs/api/cli).

## Improvements

* Oversized agent tool responses are replaced with a bounded omission record before they enter model-visible history
* Failed agent runs retain more context and report accurate total charged credits
* MCP servers support safer deletion, reauthorization, and bulk tool registration
* OpenAPI error contracts and request-body documentation now align with live API behavior
* New model options include GPT 5.6 Sol, Terra, and Luna, plus Gemini 3.6 Flash
* Agent chat validates file-size limits before starting a run
