# Maya — AI SDK presenter

> Current Strands registration, model, inputs, tools and authority.

## Role

Composes a SurfacePlan from the exact supplied UiContext entity catalog. Produces presentation structure rather than application truth.

## Contract

| Property                 | Value                                         |
| ------------------------ | --------------------------------------------- |
| Registered specialist    | `maya_presenter`                              |
| Default Bedrock model ID | `us.anthropic.claude-haiku-4-5-20251001-v1:0` |
| Typed boundary           | `UiContext → SurfacePlan`                     |
| Returned state key       | `surface_plan`                                |

## Skills

Maya has no role-specific method skill. The shared Harmonia handoff and recovery instructions are preloaded. Skill guidance is method, never evidence.

## Tools and research

The registration has no tools. It cannot fetch job state or call UI actions. The host hydrates approved entity references and registered components after validation.

## Prompt method

Choose components, hierarchy and reference graphs using the current entity catalog. Do not invent inline job facts, identifiers, lifecycle state, callbacks or executable JavaScript.

## Evidence and provenance

Only the supplied typed input and authorized returned tool evidence can support factual claims. Preloaded skills, model memory and generated prose do not establish facts. The host retains request hashes and validated references without logging private prompts or chain-of-thought.

## Authority boundary

The specialist cannot approve, grant permissions, publish, schedule an external effect, access credentials, mutate workflow state or create verification receipts. Those operations belong to deterministic host code and persisted authorization.

## Handoff

Deterministic validators bind every reference and hydrate the surface from persisted host context. An AI SDK approval control still invokes the normal authorization route.

## Runtime enforcement

`LocalStrandsTeamRuntime` creates a fresh Strands `Agent` per invocation with `structured_output_model`, `AuthorityHooks` and automatic model retries disabled. The host selects the registration, projects bounded input and validates output before a stage mutation. Provider repair follows the bounded host policy. Authenticated AWS execution remains pending live verification.
