# Full reference trajectory configuration - BookWriter-A2A # # Version: ideal trajectory derived from the code design (applies to all models) # Principle: include only steps explicitly required by the code design; do not rely on test statistics # # Code-design analysis: # 1. Three main stages are executed sequentially (orchestrator.py): # - OutlineGenerator: generate the book outline (2 agents: Researcher + Outliner) # - WriteBookChapterCrew: concurrently write multiple chapters (2 agents per chapter: Researcher + Writer) # - ReviewBookCrew: review the complete book (1 agent: Editor) # # 2. A2A-specific characteristics: # - The orchestrator calls three independent A2A servers via HTTP/JSON-RPC # - Each server runs a Crew and uses MCP tools # - Extra SPAN layers are added: a2a_call_* and *_server_execution # - Chapter writing is executed in concurrent batches (batch_size=4) # # 3. Tool usage analysis: # - OutlineGenerator: # - Researcher: bocha_websearch_tool, extract_keywords # - Outliner: no tools (pure reasoning) # - WriteBookChapterCrew (per chapter): # - Researcher: bocha_websearch_tool, extract_keywords # - Writer: count_words, analyze_chapter_quality, validate_markdown_structure # - ReviewBookCrew: # - Editor: count_book_words, analyze_book_quality, validate_book_markdown, extract_book_keywords # # 4.

Trajectory hierarchy (A2A version): # - Level 1: SPAN (book_writing_orchestrator) # - Level 2: SPAN (crew_execution) # - Level 3: SPAN (generate_outline, write_chapters, review_book) # - Level 4: SPAN (a2a_call_*: A2A call layer for each stage) # - Level 5: SPAN (*_server_execution: server-side execution layer) # - Level 6: Chain (Crew***.kickoff; UUID is wildcarded) # - Level 7: AGENT (agent role must match exactly) # - Level 8: LLM (wildcard match any model) # - Level 8: Tool (tool name must match exactly) # # 2. Differences between the A2A version and the MCP version: # - The A2A version adds two extra SPAN layers: a2a_call_* and *_server_execution # - These SPANs represent the HTTP communication between the orchestrator and A2A servers # - Tool invocation is the same, but wrapped inside the server execution layer # - In execution_path.md, SPAN names may include chapter titles (e.g., a2a_call_chapter_writer_(chapter_title)) # # 3. Wildcard handling: # - Crew_.kickoff -> Crew***.kickoff (handled automatically by evaluate_trajectory.py) # - a2a_call_chapter_writer_* -> matches any chapter title # - LLM: * -> matches any model name (e.g., gpt-5-chat-latest, deepseek-reasoner) # - Agent names must match fully (including prefixes/suffixes) # # 4. Exact match requirements: # - Orchestrator-layer SPANs: "book_writing_orchestrator", "crew_execution", "generate_outline", "write_chapters", "review_book" # - A2A call-layer SPANs: "a2a_call_outline_generator", "a2a_call_chapter_writer_*", "a2a_call_book_reviewer" (chapter writer uses wildcard) # - Server-layer SPANs: "outline_crew_server_execution", "chapter_writer_server_execution", "book_reviewer_server_execution" # - Chain: "Crew***.kickoff" (wildcard) # - Agents: names must match the role fields in agents.yaml exactly (including full names and formatting) # - LLM: "LLM: *" (wildcard match any model) # - Tools: must match MCP server tool names exactly # - Actual chapter count may be 3-5; this affects exact_match but not in_order_match # - Some tool calls may be skipped or repeated depending on agent decisions # # 5. Metric meanings: # - Exact Match: trajectories must be identical (including LLM call counts; single-chapter pattern is repeatable) # - In-order Match: extra calls are allowed, but core steps must appear in order # - Any-order Match: all required steps must be present (order ignored) # - Precision: fraction of predicted steps that are correct # - Recall: fraction of reference steps that are covered # - Single-tool Use: checks whether all required tools are used # - unique_path_ratio: path diversity (unique complete trajectories / sample count) # - path_entropy: Shannon entropy of trajectory frequencies, normalized to 0-1 # # 6. Example command: # python3 evaluate_trajectory.py --config reference_trajectory.yaml # # 7. Design notes: # - This reference represents an ideal execution path (single-chapter pattern matches 3-5 chapters) # - Three main stages execute in order: Outline → Chapters → Review # - In-order Match and Recall are often more informative for real-world behavior # # 8. Differences from real trajectories: # - The reference defines a single-chapter pattern; real runs repeat it 3-5 times (depending on outline chapter count) # - Real trajectories may contain extra LLM calls (planning, reasoning, summarization) # - Some models may call tools multiple times (retries or extra checks) # - Some models may skip certain tool calls and still produce results # - These differences reflect strategy choices and do not necessarily indicate errors # # 9. A2A-specific notes: # - The orchestrator calls three independent A2A servers via HTTP/JSON-RPC # - Each A2A server runs a Crew and uses MCP tools internally # - Extra SPAN layers are added to trace A2A communication and server-side execution # - Tool categories: search (bocha_websearch_tool), analysis (extract_keywords), # quality checks (count_words, analyze_*_quality), and format validation (validate_*) # - Chapter writing is executed in concurrent batches; each chapter has an independent trajectory # - Compared to the MCP version, the A2A version has deeper span nesting but the same core logic
