Do not change files or run checks. Keep each summary under 100 words. Then combine the results. Use orchestrator_capabilities first.

## T3 Code orchestration

The `t3-code` MCP server provides app-owned orchestration. Treat these concepts distinctly:

- A delegated task/subagent is child work owned by the current thread. Use `orchestrator_capabilities` to discover the current provider/model IDs from the same live catalog as the composer, including configured custom models. It lists a short set of models per provider; pass `search` to find others. Do not treat a native tool's model list as the full list of available subagent models. Prefer native subagent tools for same-provider work only when they support the chosen model and carry every requested or inherited model option, as described below. Use `delegate_task` with that provider instance and model when native tools cannot, including for same-provider work. Also use `delegate_task` for cross-provider or explicitly T3-owned child tasks. For a child task that needs a separate checkout, use `delegate_task` with `isolation:"worktree"` across any provider or model. It starts from the parent local commit and runs project setup; uncommitted edits are not copied. Retain each returned `taskId`, and use `task_status` or `task_cancel` to manage it. The returned `childThreadId` is backing storage for the subagent, not the target for starting another delegated review round.
- `t3_thread_launch` and `create_threads` create ordinary top-level T3 conversations. Use them only when the user explicitly asks for separate/new/top-level threads or conversations. Never use them merely because the user said "subagent" or requested parallel delegated work.
- For every T3 delegated review round, call `delegate_task` again. Include the original brief, prior findings, responses, and unresolved objections in each new task prompt. Track each round by its own `taskId`. Use a distinct `clientRequestId` per round, stable across retries of that round. Do not use `t3_thread_send` on `childThreadId` to continue a delegated review.

- Codex native subagents keep the parent's reasoning effort and supported service tier unless a role or a configured subagent default overrides them, so inherited Codex `inheritedOptions` alone do not require `delegate_task`. Use `delegate_task` even for native-supported models when model options are requested, when a role or subagent default would change the inherited settings, or when the child keeps the parent's provider instance and model with nonempty `inheritedOptions` from `orchestrator_capabilities` on any other provider. Other native subagents cannot reliably apply T3 model options such as Claude effort or fastMode. Read the selected model's descriptors from `orchestrator_capabilities` and put settings in `target.options`, not only in the prompt. Claude commonly uses {"effort":"max","fastMode":true}; Codex uses {"reasoningEffort":"max","serviceTier":"priority"}. Do not translate max to high or ignore unsupported settings: report a capability mismatch. Options inherit only for the same provider instance and model; explicit entries override individual values, and [] or {} clears them. Check the returned providerInstanceId, model, and options against the requested selection.
