# Physics Research Skill Thin wrapper that delegates physics formalization research to `physics-research-agent` subagent. **IMPORTANT**: This skill implements the skill-internal postflight pattern. After the subagent returns, this skill handles all postflight operations (status update, artifact linking, git commit) before returning. ## Context References Reference (do not load eagerly): - Path: `.claude/context/formats/return-metadata-file.md` - Metadata file schema Note: This skill is a thin wrapper with internal postflight. Context is loaded by the delegated agent. ## Trigger Conditions This skill activates when: - Task type is "physics" - Research involves dynamical systems, chaos theory, or physics formalization - Domain context files are needed for physics foundations --- ## Execution Flow ### Stage 1: Input Validation Validate required inputs: - `task_number` - Must be provided and exist in state.json - `focus_prompt` - Optional focus for research direction --- ### Stage 2: Preflight Status Update Update task status to "researching" BEFORE invoking subagent. --- ### Stage 3: Create Postflight Marker Create the marker file to prevent premature termination. --- ### Stage 4: Prepare Delegation Context Prepare delegation context for the subagent: ```json { "session_id": "sess_{timestamp}_{random}", "delegation_depth": 1, "delegation_path": ["orchestrator", "research", "skill-physics-research"], "timeout": 3600, "task_context": { "task_number": N, "task_name": "{project_name}", "description": "{description}", "task_type": "physics" }, "focus_prompt": "{optional focus}", "metadata_file_path": "specs/{NNN}_{SLUG}/.return-meta.json" } ``` --- ### Stage 5: Invoke Subagent **CRITICAL**: You MUST use the **Agent** tool to spawn the subagent. **Required Tool Invocation**: ``` Tool: Agent (NOT Skill, NOT Plan) Parameters: - subagent_type: "physics-research-agent" - prompt: [Include task_context, delegation_context, focus_prompt, metadata_file_path] - description: "Execute physics research for task {N}" ``` **DO NOT** use `Skill(physics-research-agent)` - this will FAIL. The subagent will: - Load domain context files from `.claude/context/project/physics/` - Search codebase for existing patterns - Use Mathlib lookup tools - Execute web research for physics/dynamical systems literature - Create research report in `specs/{NNN}_{SLUG}/reports/` - Write metadata to `specs/{NNN}_{SLUG}/.return-meta.json` - Return a brief text summary (NOT JSON) --- ### Stage 5b: Self-Execution Fallback **CRITICAL**: If you performed the work above WITHOUT using the Agent tool (i.e., you read files, wrote artifacts, or updated metadata directly instead of spawning a subagent), you MUST write a `.return-meta.json` file now before proceeding to postflight. Use the schema from `return-metadata-file.md` with status value "researched". If you DID use the Agent tool, skip this stage -- the subagent already wrote the metadata. --- ## Postflight (ALWAYS EXECUTE) The following stages MUST execute after work is complete, whether the work was done by a subagent or inline (Stage 5b). Do NOT skip these stages for any reason. ### Stage 6-11: Standard Postflight Parse metadata file, update task status, link artifacts (update TODO.md per `@.claude/context/patterns/artifact-linking-todo.md` with `field_name=**Research**`, `next_field=**Plan**`), git commit, cleanup, return brief summary. --- ## Error Handling Standard error handling patterns: validate inputs, handle missing metadata, non-blocking git failures. --- ## Return Format This skill returns a **brief text summary** (NOT JSON). The JSON metadata is written to the file and processed internally.
