From 0c9bdb8000e3acae32e222660cf77d06c039736f Mon Sep 17 00:00:00 2001 From: Max Date: Sat, 17 Jan 2026 12:22:23 +0800 Subject: [PATCH] Implement P3 Run Phase with Enhanced Validation and Execution Logic - Completed the implementation of the P3 Run phase, integrating task execution and validation mechanisms. - Introduced a new `RunConfig` struct to manage execution parameters such as retries and validation thresholds. - Developed a two-layer validation system using the new `yao/assert` package, supporting both natural language and structured JSON rules. - Enhanced the `RunExecution` method to execute tasks sequentially with progress tracking and a retry mechanism for validation failures. - Updated task structures to include comprehensive validation rules and expected outputs, ensuring robust task management. - Added unit tests for the new execution and validation features, achieving high test coverage across the implementation. - Revised documentation to reflect changes in the architecture and functionality of the P3 phase. --- agent/robot/DESIGN.md | 94 +- agent/robot/TECHNICAL.md | 14 +- agent/robot/TODO.md | 128 ++- agent/robot/executor/standard/run.go | 125 ++- agent/robot/executor/standard/runner.go | 445 ++++++++ agent/robot/executor/standard/tasks_test.go | 9 +- agent/robot/executor/standard/validator.go | 495 +++++++++ agent/robot/types/robot_test.go | 12 +- assert/asserter.go | 471 ++++++++ assert/asserter_test.go | 1078 +++++++++++++++++++ assert/helpers.go | 174 +++ assert/types.go | 94 ++ 12 files changed, 3086 insertions(+), 53 deletions(-) create mode 100644 agent/robot/executor/standard/runner.go create mode 100644 agent/robot/executor/standard/validator.go create mode 100644 assert/asserter.go create mode 100644 assert/asserter_test.go create mode 100644 assert/helpers.go create mode 100644 assert/types.go diff --git a/agent/robot/DESIGN.md b/agent/robot/DESIGN.md index 228b71c9..86c558a6 100644 --- a/agent/robot/DESIGN.md +++ b/agent/robot/DESIGN.md @@ -261,7 +261,7 @@ Human/Event: P1 → P2 → P3 → P4 → P5 | P0 | Inspiration | Clock + Data + News | Report | Clock only | | P1 | Goal Gen | Report + history | Goals | Always | | P2 | Task Plan | Goals + tools | Tasks | Always | -| P3 | Validator | Results | Checked results | Always | +| P3 | Run + Valid | Tasks + Experts | TaskResults | Always | | P4 | Delivery | All results | Email/File | Always | | P5 | Learning | Summary | KB entries | Always | @@ -367,22 +367,102 @@ type Task struct { ### 4.5 P3: Run +**Architecture:** P3 uses a modular design with three components: + +``` +┌─────────────────────────────────────────────────────────────┐ +│ run.go (P3 Entry) │ +│ - RunConfig: retries, threshold, continue-on-failure │ +│ - RunExecution: main execution loop │ +└─────────────────────┬───────────────────────────────────────┘ + │ + ┌────────────┴────────────┐ + ▼ ▼ +┌─────────────────┐ ┌─────────────────┐ +│ runner.go │ │ validator.go │ +│ - Runner │ │ - Validator │ +│ - Task exec │ │ - Two-layer │ +│ - Multi-turn │ │ - Rule+Semantic│ +└────────┬────────┘ └────────┬────────┘ + │ │ + │ ▼ + │ ┌─────────────────┐ + │ │ yao/assert │ + │ │ - 8 assertion │ + │ │ types │ + │ └─────────────────┘ + ▼ +┌─────────────────────────────────────────┐ +│ Executor Types │ +│ - assistant: AI Agent (multi-turn) │ +│ - mcp: MCP Tool (clientID.toolName) │ +│ - process: Yao Process │ +└─────────────────────────────────────────┘ +``` + +**Execution Flow:** + For each task: -1.
