| # Full reference trajectory configuration - RecruitmentAssistant-A2A project | |
| # | |
| # Version: ideal trajectory ported from the MCP version and adapted to the A2A architecture (applies to all models) | |
| # Principle: only include steps explicitly required by the code design; do not rely on test statistics | |
| # | |
| # Migration notes: | |
| # - This file is based on RecruitmentAssistant-MCP/reference_trajectory.yaml | |
| # - It preserves the same business roles, Agent names, LLM/Tool names, and the dynamic 3x/4x reference trajectory design | |
| # - Only the trajectory hierarchy is adapted to match the actual execution path under A2A: | |
| # * Top-level SPAN: recruitment_orchestrator | |
| # * Second-level SPAN: crew_execution | |
| # * Inside each business stage (analyze_job / evaluate_candidates / prepare_interviews) | |
| # add A2A-specific multi-layer SPANs: a2a_call_xxx → xxx_server_execution → Crew***.kickoff | |
| # | |
| # Code design + A2A architecture analysis (based on trace samples execution_path.md): | |
| # 1. The top-level orchestrator runs 3 stages sequentially: | |
| # - JobAnalysisCrew: Senior Job Requirements Analyst uses unified_web_search for market research | |
| # - CandidateEvaluationCrew: Senior Candidate Evaluator uses candidate_evaluator_pro to evaluate candidates | |
| # - InterviewCommunicationCrew: Senior Interview Materials Coordinator uses tools to generate interview materials and email templates | |
| # | |
| # 2. Tool usage (business design is consistent with the MCP version): | |
| # - Job Analysis: unified_web_search (web search for market research; recommended 3-4 calls) | |
| # - Candidate Evaluation: candidate_evaluator_pro (core scoring tool) | |
| # - Interview Communication: comprehensive_interview_material_generator + email_template_generator | |
| # | |
| # 3. A2A execution flow (adds two extra server-related SPAN layers compared to MCP): | |
| # - orchestrator creates the top-level SPAN: recruitment_orchestrator | |
| # - orchestrator creates crew_execution SPAN, then runs 3 business stages in order: | |
| # * analyze_job | |
| # * evaluate_candidates | |
| # * prepare_interviews | |
| # - Within each stage, introduce the A2A-specific 3-level nesting: | |
| # * Business method SPAN: analyze_job / evaluate_candidates / prepare_interviews | |
| # * A2A call SPAN: a2a_call_job_analysis / a2a_call_candidate_evaluation / a2a_call_interview_communication | |
| # * Server execution SPAN: job_analysis_server_execution / candidate_evaluation_server_execution / interview_communication_server_execution | |
| # * Then enter the Crew chain inside the server: Chain: Crew***.kickoff → Agent → LLM/Tool | |
| # | |
| # 4. SPAN hierarchy under A2A (abstracted from execution_path.md): | |
| # - [SPAN] recruitment_orchestrator | |
| # └─ [SPAN] crew_execution | |
| # ├─ [SPAN] analyze_job | |
| # │ └─ [SPAN] a2a_call_job_analysis | |
| # │ └─ [SPAN] job_analysis_server_execution | |
| # │ └─ [Chain] Crew***.kickoff | |
| # │ └─ [AGENT] Senior Job Requirements Analyst | |
| # ├─ [SPAN] evaluate_candidates | |
| # │ └─ [SPAN] a2a_call_candidate_evaluation | |
| # │ └─ [SPAN] candidate_evaluation_server_execution | |
| # │ └─ [Chain] Crew***.kickoff | |
| # │ └─ [AGENT] Senior Candidate Evaluator | |
| # └─ [SPAN] prepare_interviews | |
| # └─ [SPAN] a2a_call_interview_communication | |
| # └─ [SPAN] interview_communication_server_execution | |
| # └─ [Chain] Crew***.kickoff | |
| # └─ [AGENT] Senior Interview Materials Coordinator | |
| # | |
| # 5. The dynamic reference trajectory design remains unchanged (choose 3x/4x by unified_web_search count): | |
| # - If unified_web_search under analyze_job SPAN ≤ 3, use reference_trajectory_3x | |
| # - If unified_web_search under analyze_job SPAN ≥ 4, use reference_trajectory_4x | |
| # | |
| # 6. Important conventions: | |
| # - Agent role names must match the role fields in each self-hosted server's agents.yaml | |
| # - Tool names must match the actual invoked tool names: unified_web_search, candidate_evaluator_pro, | |
| # comprehensive_interview_material_generator, email_template_generator | |
| # - For [LLM], use "LLM: *" as a wildcard for any concrete model name | |

| # Notes: | |
| # - Real traces may include extra LLM calls and auxiliary tools (e.g., candidate_profile_analyzer). | |
| # They are not written into the reference trajectory, but are allowed in the In-order / Any-order / Precision / Recall metrics. | |

| # ============================================================================ | |
| # Usage - A2A architecture version | |
| # ============================================================================ | |
| # | |
| # 1. Trajectory hierarchy (tiered by type): | |
| # - Level 1: SPAN (recruitment_orchestrator) | |
| # - Level 2: SPAN (crew_execution) | |
| # - Level 3: SPAN (analyze_job / evaluate_candidates / prepare_interviews) | |
| # - Level 4: SPAN (a2a_call_job_analysis / a2a_call_candidate_evaluation / | |
| # a2a_call_interview_communication) | |
| # - Level 5: SPAN (job_analysis_server_execution / | |
| # candidate_evaluation_server_execution / | |
| # interview_communication_server_execution) | |
| # - Level 6: Chain (Crew***.kickoff) | |
| # - Level 7: AGENT (Senior roles for each stage) | |
| # - Level 8: LLM / Tool (alternating) | |
| # | |
| # 2. Wildcards and exact matching: | |
| # - SPAN names: must exactly match the names in this file | |
| # - Chain name: "Crew***.kickoff"; evaluate_trajectory.py will automatically normalize | |
| # the actual Crew_<UUID>.kickoff into this form | |
| # - AGENT names: exact match the role fields in agents.yaml (e.g., | |
| # "Senior Job Requirements Analyst") | |
| # - LLM: use "LLM: *" as a wildcard to match any model (gpt-5-chat-latest, | |
| # deepseek-reasoner, gemini-2.5-flash, qwen3-235b-a22b, etc.) | |
| # - Tool names: exact match tool names | |
| # | |
| # 3. Metric meanings (consistent with the MCP version): | |
| # - Exact Match: Predicted trajectory exactly matches the reference trajectory in length and every step | |
| # - In-order Match: Reference trajectory is a subsequence of the predicted trajectory, allowing extra steps | |
| # - Any-order Match: Only requires the presence of all necessary steps, ignoring order | |
| # - Precision: Proportion of steps in the predicted trajectory that are considered correct | |
| # - Recall: Proportion of steps in the reference trajectory that are covered | |
| # - Single-tool Use: Average usage of each tool in target_tools | |
| # - unique_path_ratio: Number of unique complete trajectories / total samples | |
| # - path_entropy: Shannon entropy based on trajectory frequencies, normalized to 0-1 | |
| # | |
| # 4. How to use dynamic reference trajectories: | |
| # - evaluate_trajectory.py automatically counts unified_web_search calls under analyze_job SPAN | |
| # for each sample: | |
| # * ≤ 3 → use reference_trajectory_3x | |
| # * ≥ 4 → use reference_trajectory_4x | |
| # - This treats models with fewer/more searches more fairly. | |
| # | |
| # 5. Run example: | |
| # - Run in the RecruitmentAssistant-A2A directory: | |
| # python3 evaluate_trajectory.py --config reference_trajectory.yaml | |
| # | |
| # 6. Possible differences vs. real A2A traces: | |
| # - Real traces may include: | |
| # * More LLM calls (thinking / planning / self-reflection) | |
| # * Extra tools (e.g., multiple calls to candidate_profile_analyzer) | |
| # * Orchestrator-level retries or business retries | |
| # - These are not written into the reference trajectory, but will naturally be reflected in Precision/Recall; | |
| # when analyzing results, focus on In-order Match, Recall, and path diversity metrics. | |
