- Rename all PascalCase types: OhMyOpenCodePlugin → OhMyOpenAgentPlugin, etc.
- 231 OhMyOpenAgent references across ~60 files
- Centralize 4 PACKAGE_NAME constants to import from plugin-identity.ts
- Update src/plugin-config.ts to use CONFIG_BASENAME from plugin-identity
Wave 3 Tasks 5 & 6 complete.
Align runtime defaults, tests, docs, and generated artifacts with the newer GPT-5.4 baseline. Keep think-mode and prompt-routing expectations consistent after the model version bump.
- runtime-fallback: guard session.error with sessionRetryInFlight to prevent
double-advance during active retry; expand session.stop abort to include
sessionAwaitingFallbackResult; remove premature pendingFallbackModel clearing
from auto-retry finally block
- hashline-edit: add HASHLINE_LEGACY_REF_PATTERN for backward-compatible
LINE:HEX dual-parse in parseLineRef and normalizeLineRef
- tmux-subagent: defer session on null queryWindowState; unconditionally
re-queue deferred session on spawn failure (not just close+spawn)
- ultrawork-db: wrap new Database(dbPath) in try/catch to handle corrupted DB
- event: add try/catch guards around model-fallback logic in message.updated,
session.status, and session.error handlers
Make provider auto-retry signal detection respect timeout_seconds setting:
- When timeout_seconds=0, disable quota-based fallback escalation
- Only treat auto-retry signals as errors when timeout is enabled
- Add test to verify behavior when timeout_seconds is disabled
- Update documentation to explain timeout_seconds=0 behavior
This allows users to disable timeout-based fallbacks while keeping
error-based fallback functionality intact.
Refactor retry signal detection to be provider-agnostic:
- Replace hardcoded Copilot/OpenAI checks with generic pattern matching
- Detect any provider message containing limit/quota keywords + [retrying in X]
- Add OpenAI pattern: 'usage limit has been reached [retrying in X]'
- Update logging to use generic 'provider' instead of specific names
- Add 'usage limit has been reached' to RETRYABLE_ERROR_PATTERNS
This enables fallback escalation for any provider that signals automatic
retries due to quota/rate limits, not just Copilot and OpenAI.
Closes PR discussion: generalize retry pattern detection
Bug fixes:
1. extractStatusCode: handle nested data.statusCode (Anthropic error structure)
2. Error regex: relax credit.*balance.*too.*low pattern for multi-char gaps
3. Zod schema: bump max_fallback_attempts from 10 to 20 (config rejected silently)
4. getFallbackModelsForSession: fallback to sisyphus/any agent when session.error lacks agent
5. Model detection: derive model from agent config when session.error lacks model info
6. Auto-retry: resend last user message with fallback model via promptAsync
7. Persistent fallback: override model on every chat.message (not just pendingFallbackModel)
8. Manual model change: detect UI model changes and reset fallback state
9. Agent preservation: include agent in promptAsync body to prevent defaulting to sisyphus
Additional:
- Add sessionRetryInFlight guard to prevent double-retries
- Add resolveAgentForSession with 3-tier resolution (event → session memory → session ID)
- Add normalizeAgentName for display names like "Prometheus (Planner)" → "prometheus"
- Add resolveAgentForSessionFromContext to fetch agent from session messages
- Move AGENT_NAMES and agentPattern to module scope for reuse
- Register runtime-fallback hooks in event.ts and chat-message.ts
- Remove diagnostic debug logging from isRetryableError
- Add 400 to default retry_on_errors and credit/balance patterns to RETRYABLE_ERROR_PATTERNS
- Add normalizeFallbackModels helper to centralize string/array normalization (P3)
- Export RuntimeFallbackConfig and FallbackModels types from config/index.ts
- Fix agent detection regex to use word boundaries for sessionID matching
- Improve tests to verify actual fallback switching logic (not just log paths)
- Add SessionCategoryRegistry cleanup in executeSyncTask on completion/error (P2)
- All 24 runtime-fallback tests pass, 115 delegate-task tests pass
- Add Category-level fallback_models support in getFallbackModelsForSession()
- Try agent-level fallback_models first
- Then try agent's category fallback_models
- Support all builtin agents including hephaestus, sisyphus-junior, build, plan
- Expand agent name recognition regex to include:
- hephaestus, sisyphus-junior, build, plan, multimodal-looker
- Add comprehensive test coverage (6 new tests, total 24):
- Model switching via chat.message hook
- Agent-level fallback_models configuration
- SessionID agent pattern detection
- Cooldown mechanism validation
- Max attempts limit enforcement
All 24 tests passing

Add configuration schemas for runtime model fallback feature:
- RuntimeFallbackConfigSchema with enabled, retry_on_errors,
max_fallback_attempts, cooldown_seconds, notify_on_fallback
- FallbackModelsSchema for init-time fallback model selection
- Add fallback_models to AgentOverrideConfigSchema and CategoryConfigSchema
- Export types and schemas from config/index.ts
