## TASK ASSIGNMENT

### MANDATORY FIRST STEPS
1. Read your FULL task JSON: ${sessionFolder}/{task_json_path}
   - CSV row is a brief — task JSON has pre_analysis, flow_control, convergence, and full context
2. Read shared discoveries: ${sessionFolder}/discoveries.ndjson (if exists)
3. Read project context: .workflow/project-tech.json (if exists)

---

## Your Task

**Task ID**: {id}
**Title**: {title}
**Description**: {description}
**Agent Type**: {agent}
**Scope**: {scope}

### Task JSON (full details)
Read: ${sessionFolder}/{task_json_path}

### Implementation Hints & Reference Files
{hints}

> Format: \`tips text || file1;file2\`. Read ALL reference files (after ||) before starting. Apply tips (before ||) as guidance.

### Execution Directives
{execution_directives}

> Commands to run for verification, tool restrictions, or environment requirements.

### Acceptance Criteria
{acceptance_criteria}

### Previous Context (from predecessor tasks)
{prev_context}

### Project Context
${contextBlock}

---

## Execution Protocol

1. **Read task JSON**: Load ${sessionFolder}/{task_json_path} for full task details including pre_analysis steps and flow_control
2. **Check execution method**: If task JSON has \`execution_config.method\`, follow it (agent vs cli mode)
3. **Execute pre_analysis**: If task JSON has \`pre_analysis\` steps, run them first to gather context
4. **Read references**: Parse {hints} — read all files listed after \`||\` to understand existing patterns
5. **Read discoveries**: Load ${sessionFolder}/discoveries.ndjson for shared findings
6. **Use context**: Apply predecessor tasks' findings from prev_context above
7. **Stay in scope**: ONLY create/modify files within {scope} — do NOT touch files outside this boundary
8. **Apply hints**: Follow implementation tips from {hints} (before \`||\`)
9. **Execute**: Implement the task as described in the task JSON
10. **Generate summary**: Write execution summary to ${sessionFolder}/.summaries/{id}-summary.md with sections:
    ## Summary, ## Files Modified (as \`- \\\`path\\\`\` list), ## Key Decisions, ## Tests
11. **Run directives**: Execute commands from {execution_directives} to verify your work
12. **Update TODO**: In ${sessionFolder}/TODO_LIST.md, change \`- [ ] {id}\` to \`- [x] {id}\`
13. **Share discoveries**: Append findings to shared board:
    \`\`\`bash
    echo '{"ts":"<ISO8601>","worker":"{id}","type":"<type>","data":{...}}' >> ${sessionFolder}/discoveries.ndjson
    \`\`\`
14. **Report result**: Return JSON via report_agent_job_result

### Discovery Types to Share
- \`code_pattern\`: {name, file, description} — reusable patterns found
- \`integration_point\`: {file, description, exports[]} — module connection points
- \`convention\`: {naming, imports, formatting} — code style conventions
- \`blocker\`: {issue, severity, impact} — blocking issues encountered

---

## Output (report_agent_job_result)

Return JSON:
{
  "id": "{id}",
  "status": "completed" | "failed",
  "findings": "Key discoveries and implementation notes (max 500 chars)",
  "files_modified": ["path1", "path2"],
  "tests_passed": true | false,
  "acceptance_met": "Summary of which acceptance criteria were met/unmet",
  "error": ""
}

**IMPORTANT**: Set status to "completed" ONLY if:
- All acceptance criteria are met
- Verification directives pass (if any)
Otherwise set status to "failed" with details in error field.
