Metadata

  • Commit Message: feat(actor): compile hierarchical actor configs to LangGraph
  • Branch: feature/m3-actor-compiler

Background

The actor compiler translates hierarchical YAML graphs into LangGraph StateGraph nodes and edges with LSP bindings applied per node. Subgraph resolution includes cycle detection and clear errors for missing nodes or invalid entry/exit mapping. The compiled graphs are executable by PlanExecutor through the tool runtime.

Acceptance Criteria

  • Implement actor compiler to translate hierarchical YAML graphs into LangGraph StateGraph nodes/edges with LSP bindings applied per node.
  • Add subgraph resolution with cycle detection and clear errors for missing nodes or invalid entry/exit mapping.
  • Add runtime wiring so PlanExecutor can execute compiled actors using the tool runtime and action-configured roles.
  • Add compiler output metadata (node IDs, tool nodes, LSP bindings) for diagnostics and CLI inspection.
  • Update docs/reference/actor_compiler.md with compilation pipeline, node binding, and error modes.

Definition of Done

This issue is complete when:

  • All subtasks below are completed and checked off.
  • A Git commit is created where the first line of the commit message matches
    the Commit Message in Metadata exactly, followed by a blank line, then
    additional lines providing relevant details about the implementation. The
    commit body should be appropriate in size for a commit message and relatively
    complete in describing what was done.
  • The commit is pushed to the remote on the branch matching the Branch in
    Metadata exactly.
  • The commit is submitted as a pull request to master, reviewed, and
    merged before this issue is marked done.

Subtasks

  • Implement actor compiler to translate hierarchical YAML graphs into LangGraph StateGraph nodes/edges with LSP bindings applied per node.
  • Add subgraph resolution with cycle detection and clear errors for missing nodes or invalid entry/exit mapping.
  • Add runtime wiring so PlanExecutor can execute compiled actors using the tool runtime and action-configured roles.
  • Add compiler output metadata (node IDs, tool nodes, LSP bindings) for diagnostics and CLI inspection.
  • Update docs/reference/actor_compiler.md with compilation pipeline, node binding, and error modes.
  • Tests (Behave): Add scenarios for compile success/failure, subgraph resolution, and node wiring validation.
  • Tests (Robot): Add Robot smoke test compiling and running a multi-node actor graph with LSP bindings stubbed.
  • Tests (ASV): Add benchmarks/actor_compiler_bench.py for compile overhead.
  • Verify coverage >=97% via nox -s coverage_report. If coverage is <97% then review the current unit test coverage report at build/coverage.xml and use it to write new Behave based unit tests to improve code coverage. Specifically, write Behave style unit tests that are descriptively named and specifically improves coverage on whichever file has the most uncovered lines by writing tests that will target the uncovered lines in the report. Once that is done rerun nox -s coverage_report to verify all tests pass and coverage is above >=97%. Only mark this as complete once coverage is >=97%, if not repeat this task as many times as is needed until coverage reaches >=97%.
  • Run nox (all default sessions, including benchmark), fix any errors if needed ensuring nox passes across entire code base, do not ignore any failure even if it seems unrelated to this commit, fix it.

Implementation Notes

Design Decisions

  • Created src/cleveragents/actor/compiler.py as a new module containing the ActorCompiler class and supporting types (CompilationMetadata, CompiledNode, ActorCompilationError, CycleDetectedError, InvalidEntryPointError, MissingNodeError).
  • The compiler takes an ActorConfigSchema of type GRAPH and translates its nodes/edges into LangGraph-compatible structures.
  • Subgraph resolution uses DFS with a visited set for cycle detection, emitting clear error paths (e.g., actorA -> actorB -> actorA).
  • LSP bindings are applied per-node from the node configuration.
  • CompilationMetadata captures node IDs, tool nodes, LSP bindings, and subgraph references for diagnostics.
  • Exported new types from src/cleveragents/actor/__init__.py.

Testing

  • Behave: 13 scenarios in features/actor_compiler.feature covering compile success, cycle detection, missing node errors, invalid entry points, LSP binding, and metadata generation.
  • Robot: 4 smoke tests in robot/actor_compiler.robot.
  • ASV: Benchmarks in benchmarks/actor_compiler_bench.py for simple/large compile, metadata, and subgraph performance.

Quality Gates

All nox sessions passed: lint, format, typecheck (0 errors), security_scan, dead_code, build, docs, unit_tests, integration_tests.
