Replace promptAsync + manual polling loop with promptSyncWithModelSuggestionRetry
(session.prompt) which blocks until the LLM response completes. This matches
OpenCode's native task tool behavior and fixes empty/broken responses that
occurred when polling declared stability prematurely.
Applied to both executeSyncTask and executeSyncContinuation paths.
Remove 'prometheus' from PLAN_AGENT_NAMES so isPlanAgent() no longer
matches prometheus. The only remaining connection is model inheritance
via buildPlanDemoteConfig() in plan-model-inheritance.ts.
- Remove 'prometheus' from PLAN_AGENT_NAMES array
- Update self-delegation error message to say 'plan agent' not 'prometheus'
- Update tests: prometheus is no longer treated as a plan agent
- Update task permission: only plan agents get task tool, not prometheus
Previously, demoted plan agent only received { mode: 'subagent' } with no
model settings, causing fallback to step-3.5-flash. Now inherits all
model-related settings (model, variant, temperature, top_p, maxTokens,
thinking, reasoningEffort, textVerbosity, providerOptions) from the
resolved prometheus config. User overrides via agents.plan.* take priority.
Prompt, permission, description, and color are intentionally NOT inherited.
When Anthropic models reject requests with 'This model does not support
assistant message prefill', detect this as a recoverable error type and
automatically send 'Continue' once to resume the conversation.
Extends session-recovery hook with new 'assistant_prefill_unsupported'
error type. The existing session.error handler in index.ts already sends
'continue' after successful recovery, so no additional logic needed.
The ralph-loop hook calls promptAsync in the implementation, but the
test mock only defined prompt(). Added promptAsync with identical
behavior to make tests pass.
- All 38 ralph-loop tests now pass
- Total test suite: 2361 pass, 3 fail (unrelated to this change)
PR #1620 migrated all prompt calls from session.prompt (blocking) to
session.promptAsync (fire-and-forget HTTP 204). This broke look_at which
needs the multimodal-looker response to be available immediately after
the prompt call returns.
Fix: add promptSyncWithModelSuggestionRetry() that uses session.prompt
(blocking) with model suggestion retry support. look_at now uses this
sync variant while all other callers keep using promptAsync.
- Add promptSyncWithModelSuggestionRetry to model-suggestion-retry.ts
- Switch look_at from promptWithModelSuggestionRetry to sync variant
- Add comprehensive tests for the new sync function
- No changes to other callers (delegate-task, background-agent)
