Summary

Fixes built-in actors (e.g., openai/gpt-4, anthropic/claude-3-opus) to work with agents actor run command by generating and persisting v3 YAML text with required type and description fields.

Changes

Core Implementation

  • src/cleveragents/actor/registry.py: Added _generate_builtin_actor_yaml() helper method that generates spec-compliant v3 YAML text for built-in actors
  • src/cleveragents/actor/registry.py: Modified ensure_built_in_actors() to generate and persist yaml_text via upsert_actor()

Testing

  • features/builtin_actor_v3_yaml.feature: BDD scenarios covering v3 YAML format validation
  • features/steps/builtin_actor_v3_yaml_steps.py: Step definitions for new scenarios
  • tests/actor/test_registry_builtin_yaml.py: Unit tests for YAML generation and schema validation

Documentation

  • CHANGELOG.md: Added entry under Fixed section

Technical Details

Root Cause

Built-in actors were created without yaml_text, causing ReactiveConfigParser._is_v3_format() to fail (no type key), resulting in:

  • Empty agents and routes dictionaries
  • run_single_shot() returning empty output silently
  • No error message to indicate what went wrong

Solution

Generated v3 YAML includes:

name: openai/gpt-4
type: llm
model: openai/gpt-4
description: Built-in actor from provider registry (openai/gpt-4)
provider: openai
capabilities:
  supports_streaming: true
  supports_tool_calls: true
  supports_vision: false
  max_context_length: 4096
  supports_json_mode: false
unsafe: false
source: provider-registry

Backward Compatibility

  • Existing built-in actors automatically refreshed on next ensure_built_in_actors() call
  • No database migration needed
  • No breaking changes to actor list/show/remove commands

Test Step Design Notes

The agents actor run scenario uses a dedicated mock step
I call agents actor run with mock "{actor_name}" rather than the generic
I run "{command}" step (which invokes the real CLI with no LLM mocking).
This keeps the scenario firmly in unit-test territory — it exercises only the
actor-lookup and v3-format-check logic, not the LLM invocation path.

Built-in actors (e.g., openai/gpt-4, anthropic/claude-3-opus) were failing
silently with agents actor run because they lacked the required v3 type
field in their stored configuration. The ReactiveConfigParser._is_v3_format()
check failed, resulting in empty agents/routes dictionaries and no output.

This fix adds _generate_builtin_actor_yaml() helper to ActorRegistry that
generates spec-compliant v3 YAML text including:
- type: llm (required for v3 format recognition)
- description (required by v3 schema)
- name, model, provider, capabilities, unsafe, source fields

The ensure_built_in_actors() method now calls this helper and persists
yaml_text via upsert_actor(), ensuring built-in actors work identically
to custom actors with the agents actor run command.

Existing built-in actors will be automatically refreshed on next startup
since they are regenerated from the provider registry - no database
migration needed.

Added:
- _generate_builtin_actor_yaml() helper method
- BDD feature file with scenarios for v3 YAML format
- Step definitions for new BDD scenarios
- Unit tests covering YAML generation and schema validation
- CHANGELOG entry

Review Summary — PR #10894: fix(actor): add v3 YAML text generation for built-in actors

CI Status

All 14 CI checks passing (lint, typecheck, security, unit_tests, integration_tests, e2e_tests, coverage, build, docker, helm, push-validation, status-check). CI is green.

Checklist Results

  1. CORRECTNESS — The code correctly addresses the root cause: built-in actors were persisted without yaml_text, causing ReactiveConfigParser._is_v3_format() to fail. The fix generates spec-compliant v3 YAML with the required type: llm and description fields, which is then passed to upsert_actor(). The Actor domain model has a yaml_text field, so persistence is correct. All acceptance criteria from the PR body are met.

  2. SPECIFICATION ALIGNMENT — The generated YAML follows the ActorConfigSchema format (with type key set to llm), which is_v3_yaml() detects correctly. All required top-level fields (name, type, description) are present. The model field includes the full provider/model path (provider/model), consistent with how the spec expects model references. source: provider-registry correctly identifies this as auto-generated rather than user-authored.

  3. TEST QUALITY — Comprehensive test coverage:

    • BDD: 4 feature scenarios in builtin_actor_v3_yaml.feature covering type field presence, required v3 fields, CLI command execution, and schema validation. Well-named scenarios that read as living documentation.
    • Unit tests: 14 test methods in a clean test class structure (TestGenerateBuiltinActorYaml and TestEnsureBuiltInActorYaml). Covers individual YAML fields, v3 detection, schema validation, capabilities inclusion, slash sanitization (OpenRouter edge case), multi-provider scenarios, and empty-provider edge case.
    • Edge cases tested: no providers (returns empty), slash sanitization, capabilities with None values, multiple providers.
    • Step definitions import from existing actor_registry_steps.py stubs, maintaining consistency with the existing test architecture.
  4. TYPE SAFETY — All function signatures and return types are annotated. _generate_builtin_actor_yaml uses dict[str, Any] and ProviderCapabilities | None properly. The Any import from typing is used correctly. No # type: ignore comments anywhere.

  5. READABILITY — Clean, descriptive names. The _generate_builtin_actor_yaml method clearly separates concern from ensure_built_in_actors. The YAML dict construction with None-value filtering (yaml_dict = {k: v for k, v in ...}) is concise and readable. Comments in ensure_built_in_actors explaining the name sanitization vs. raw provider/model intent are helpful.

  6. PERFORMANCE — Lightweight change. YAML generation runs once per configured provider during ensure_built_in_actors(). No loops or N+1 patterns. The sort_keys=False parameter in yaml.safe_dump() avoids unnecessary sorting overhead.

  7. SECURITY — No hardcoded secrets, tokens, or credentials. Uses yaml.safe_dump() (not yaml.dump()), which prevents arbitrary Python object instantiation. No external inputs involved. The description string is constructed from provider/model names which are already validated by the provider registry.

  8. CODE STYLE — SOLID principles followed: single responsibility (YAML generation is isolated in _generate_builtin_actor_yaml). Files are under 500 lines (registry.py ~470 lines). Follows ruff conventions. Consistent with the existing codebase patterns. Note: pre-existing issues (duplicate comment block on lines 334-335, duplicate @staticmethod decorator in config.py line 43) are NOT introduced by this PR and are noted as non-blocking for follow-up.

  9. DOCUMENTATION _generate_builtin_actor_yaml has a thorough docstring covering purpose, args, and return type. The ensure_built_in_actors docstring was updated to document the new v3 YAML behavior. Changelog entry is clear and user-facing. The BDD scenarios serve as living documentation for the feature.

  10. COMMIT AND PR QUALITY — Single atomic commit with correct conventional changelog format (fix(actor): add v3 YAML text generation for built-in actors). Changes are tightly scoped: only YAML text generation for built-in actors. 5 changed files, 688 additions, 1 deletion. Clean diff with no unrelated changes.

Non-blocking observations (not preventing approval):

  1. Comment 1, line 334: # Legacy upsert (preserved for backward compatibility) appears twice (lines 334-336). This is an existing artifact, not PR-introduced. Worth cleaning up in a follow-up.

  2. Test stub duplication: The step file builtin_actor_v3_yaml_steps.py defines _StubActorService and _StubProviderRegistry classes, then also imports them from features.steps.actor_registry_steps. Consider deduplicating — either the steps file should only use the existing stubs, or the stubs should be moved to a shared test utilities module. This is a pre-existing pattern in the codebase though.

  3. Changelog entry: Could be slightly more concise and could include the PR number (#10894) in addition to the issue number for traceability. Minor suggestion.

Conclusion

All 10 checklist categories pass. The PR correctly and comprehensively addresses the bug described in #10861/#10883. The fix is minimal, well-tested, and follows project conventions. CI is fully green. No blocking issues found. Ready for merge.

Comments in `ensure_built_in_actors` explaining the name sanitization vs. raw provider/model intent are helpful. 6. **PERFORMANCE** ✅ — Lightweight change. YAML generation runs once per configured provider during `ensure_built_in_actors()`. No loops or N+1 patterns. The `sort_keys=False` parameter in `yaml.safe_dump()` avoids unnecessary sorting overhead. 7. **SECURITY** ✅ — No hardcoded secrets, tokens, or credentials. Uses `yaml.safe_dump()` (not `yaml.dump()`), which prevents arbitrary Python object instantiation. No external inputs involved. The description string is constructed from provider/model names which are already validated by the provider registry. 8. **CODE STYLE** ✅ — SOLID principles followed: single responsibility (YAML generation is isolated in `_generate_builtin_actor_yaml`). Files are under 500 lines (registry.py ~470 lines). Follows ruff conventions. Consistent with the existing codebase patterns. Note: pre-existing issues (duplicate comment block on lines 334-335, duplicate `@staticmethod` decorator in config.py line 43) are NOT introduced by this PR and are noted as non-blocking for follow-up. 9. **DOCUMENTATION** ✅ — `_generate_builtin_actor_yaml` has a thorough docstring covering purpose, args, and return type. The `ensure_built_in_actors` docstring was updated to document the new v3 YAML behavior. Changelog entry is clear and user-facing. The BDD scenarios serve as living documentation for the feature. 10. **COMMIT AND PR QUALITY** ✅ — Single atomic commit with correct conventional changelog format (`fix(actor): add v3 YAML text generation for built-in actors`). Changes are tightly scoped: only YAML text generation for built-in actors. 5 changed files, 688 additions, 1 deletion. Clean diff with no unrelated changes. ### Non-blocking observations (not preventing approval): 1. **Comment 1, line 334**: `# Legacy upsert (preserved for backward compatibility)` appears twice (lines 334-336). This is an existing artifact, not PR-introduced. Worth cleaning up in a follow-up. 2. **Test stub duplication**: The step file `builtin_actor_v3_yaml_steps.py` defines `_StubActorService` and `_StubProviderRegistry` classes, then also imports them from `features.steps.actor_registry_steps`. Consider deduplicating — either the steps file should only use the existing stubs, or the stubs should be moved to a shared test utilities module. This is a pre-existing pattern in the codebase though. 3. **Changelog entry**: Could be slightly more concise and could include the PR number (#10894) in addition to the issue number for traceability. Minor suggestion. ### Conclusion All 10 checklist categories pass. The PR correctly and comprehensively addresses the bug described in #10861/#10883. The fix is minimal, well-tested, and follows project conventions. CI is fully green. No blocking issues found. Ready for merge.
