The spawn dialog's bundled lists miss versioned Claude models and current OpenCode choices. It also applies a hidden Codex effort default without an explicit model-aware control.

Discovers installed-CLI catalogs for localhost brokers using portable PATH/home resolution, bounded discovery, a shared ten-minute cache and per-provider fallback. The dialog offers advertised effort levels; CLI defaults remain unless explicitly overridden. Structured effort reaches local/cloud transports. Local validation translates it into native Claude/Codex arguments or process-local OpenCode model/variant configuration, preserving explicit PTY launch settings.

Validation:

• 671 tests passed (418 dashboard, 253 server), including regressions for aliases, advertised variants, configuration isolation and agent defaults. The server suite passed with two workers after three existing tests timed out in the default parallel run.
• Windows: both package typechecks, dashboard-server build, production UI build and dashboard server-entry build passed.
• Isolated production-build browser smoke verified versioned models, current OpenCode options, effort selection/reset and unsupported-model behavior.
• Live installed-CLI discovery, native Windows OpenCode executable resolution and a controlled default-agent configuration lookup passed without model prompts.

Compatibility:

• Remote brokers retain the bundled registry; cloud adapters forward effort to their host API. The legacy orchestrator hides the control because its API cannot carry effort.
• OpenCode effort requires harnessConfig.env support (verified with broker 14). Implicit default-agent lookup requires an absolute worker directory; remote brokers, custom launchers or unavailable defaults require an explicit --agent. Dashboard inline configuration is inherited only for local brokers. Older brokers and native broker/model execution are not covered by the transport tests.
• Linux/macOS execution awaits CI/maintainer verification. Excludes generated assets, personal paths, credentials and self-hosting patches.

Note

Medium Risk
Changes agent spawn payloads and runs local CLI discovery with harness/env rewriting for OpenCode; mitigated by validation, timeouts, and remote-broker isolation but still affects launch behavior.

Overview
Adds local model discovery for localhost brokers: Claude/OpenCode via bounded CLI probes and Codex via models_cache.json, with a 10-minute shared cache, per-provider fallback to bundled/cached catalogs, alias resolution, and catalogWarnings when discovery fails. Remote brokers keep the bundled registry only.

The Spawn Agent flow gains an opt-in Reasoning effort control driven by per-model metadata from /api/models, replacing the previous silent Codex effort injection in spawn commands. Effort is sent as a separate field through local and cloud spawn APIs; the broker proxy validates it against the catalog and returns HTTP 400 when unsupported.

Server-side translation maps effort to native launch settings: --effort for Claude, model_reasoning_effort for Codex, and process-local OPENCODE_CONFIG_CONTENT (with default-agent discovery via debug config on local brokers). The legacy orchestrator path hides the control and errors if effort is set. README documents discovery, caching, and compatibility limits.

📝 Walkthrough

The change adds local model discovery and a /api/models catalog response. The dashboard adds a model-aware reasoning-effort selector and forwards explicit selections through supported spawn APIs. The broker validates selections and applies provider-specific launch configuration.

Changes: Model discovery and reasoning effort

Layer / File(s)	Summary
Model catalog discovery and delivery packages/dashboard-server/src/lib/model-catalog.ts, packages/dashboard-server/src/lib/model-catalog.test.ts, packages/dashboard-server/src/routes/models.ts, packages/dashboard-server/src/routes/models.test.ts, packages/dashboard-server/src/proxy-server.ts, packages/dashboard-server/src/proxy-server.test.ts	The server parses Claude, OpenCode, and Codex model data. Local discovery uses a ten-minute cache, shared in-flight loads, bounded CLI processes, and provider-specific fallback options. The models route returns the catalog, and server registration supplies it to both model and broker-proxy routes.
Dashboard effort selection and forwarding packages/dashboard/src/components/SpawnModal.tsx, packages/dashboard/src/components/SpawnModal.test.tsx, packages/dashboard/src/components/App.tsx, packages/dashboard/src/providers/AgentProvider.tsx, packages/dashboard/src/providers/AgentProvider.test.tsx, packages/dashboard/src/types/index.ts, packages/dashboard/src/adapters/types.ts, packages/dashboard/src/lib/model-options.ts, packages/dashboard/src/components/hooks/useModelOptions.ts, README.md	The modal shows effort options supported by the selected model and clears invalid selections. Spawn requests carry an explicit effort separately from the model command. The dashboard enables the control only for supported contexts; orchestrator spawning rejects an explicit effort.
Broker validation and CLI configuration packages/dashboard-server/src/lib/spawn-effort.ts, packages/dashboard-server/src/routes/broker-proxy.ts, packages/dashboard-server/src/routes/broker-proxy.test.ts	The broker checks effort values against the model catalog and returns HTTP 400 for invalid selections. It applies provider-specific flags for Claude and Codex, and updates the selected OpenCode agent configuration before forwarding the request.

Merge Risk: 🟡 Moderate · up to 6229d

A remote broker can receive the dashboard host’s OpenCode configuration, potentially including credentials. Restrict that fallback to local brokers before merging.

_{I’m a rabbit with a model list,
I pick an effort, neat and clear.
The broker checks the choice I sent,
Then shapes the launch for each CLI.
I twitch my nose and hop away,
With cached choices tucked in tow.}
