Extend actor YAML schema to support hierarchical graphs with explicit
node types (agent, tool, conditional, subgraph), per-node LSP bindings
(lsp_binding with server, languages, auto, capabilities), and tool-source
references (skills, mcp_servers, agent_skills).
Add schema validation for namespaced actor references, duplicate node IDs,
edge target existence, and graph reachability — all nodes must be reachable
from entry_node via explicit edges or conditional node routing targets.
Update loader to report YAML parse errors with precise line/column positions
and schema validation errors with dotted field paths and remediation hints
pointing to docs/reference/actor_config.md.
Add docs/reference/actor_config.md as the practical configuration reference
covering hierarchical graph examples, node type table, topology rules, and
common error cases with fix guidance.
Refresh examples/actors/graph_workflow.yaml to replace deprecated actor_path
with actor_ref. Add benchmarks/actor_yaml_bench.py for schema load overhead.
Tests: 95 Behave scenarios, 10 Robot smoke tests (including hierarchical
loader smoke test), security scan clean, coverage 99% (threshold 97%).
ISSUES CLOSED: #157
Add 5 example actor configurations demonstrating all actor types:
Simple Examples:
- simple_llm.yaml: Basic LLM actor with code review prompt
- llm_with_tools.yaml: LLM with mix of tool references and inline tools
- tool_collection.yaml: Tool-only actor (no LLM)
Graph Examples:
- simple_graph.yaml: 3-node linear workflow (extract → analyze → summarize)
- graph_workflow.yaml: Complex TDD workflow with 10 nodes
* Conditional routing based on test results
* Retry logic with max attempts
* Subgraph composition (code review)
* Error escalation paths
Each example demonstrates:
- Proper namespaced naming (namespace/name)
- Type-specific configurations
- Context and memory settings
- Environment variable usage
- Tool definitions (inline and references)
