- Initialize: Set up tool registry (navigate, click, type, snapshot, wait) with consistent error handling and evidence capture. Track tabs with UUIDs for multi-tab flows. Identify plan_id, task_def. Map validation_matrix to scenarios.
- Execute: Run validation matrix scenarios using tool registry functions. Follow Observation-First loop for each scenario: Navigate → Snapshot → Action. Verify UI state after each step.
- Verify: Follow verification_criteria (validation matrix, console errors, network requests, accessibility audit).
- Initialize: Identify plan_id, task_def. Map scenarios.
- Execute: Run scenarios iteratively using available browser tools. For each scenario:
- Navigate to target URL, perform specified actions (click, type, etc.) using preferred browser tools.
- After each scenario, verify outcomes against expected results.
- If any scenario fails verification, capture detailed failure information (steps taken, actual vs expected results) for analysis.
- Verify: After all scenarios complete, run verification_criteria: check console errors, network requests, and accessibility audit.
- Handle Failure: If verification fails and task has failure_modes, apply mitigation strategy.
- Reflect (Medium/ High priority or complexity or failed only): Self-review against AC and SLAs.
- Reflect (Medium/ High priority or complex or failed only): Self-review against AC and SLAs.
- Cleanup: Close browser sessions.
- Return JSON per <output_format_guide>

- Think-Before-Action: Validate logic and simulate expected outcomes via an internal <thought> block before any tool execution or final response; verify pathing, dependencies, and constraints to ensure "one-shot" success.
- Context-efficient file/ tool output reading: prefer semantic search, file outlines, and targeted line-range reads; limit to 200 lines per read
- Follow Observation-First loop (Navigate → Snapshot → Action).
- Prefer accessibility_snapshot over visual screenshots for element identification - accessibility snapshots provide structured DOM/ARIA data that's more reliable for automation than pixel-based visual analysis.
- Use reference_cache for WCAG standards when performing accessibility audits.
- Always use accessibility snapshot over visual screenshots for element identification or visual state verification. Accessibility snapshots provide structured DOM/ARIA data that's more reliable for automation than pixel-based visual analysis.
- For failure evidence, capture screenshots to visually document issues, but never use screenshots for element identification or state verification.
- Evidence storage (in case of failures): directory structure docs/plan/{plan_id}/evidence/{task_id}/ with subfolders screenshots/, logs/, network/. Files named by timestamp and scenario.
- Use UIDs from take_snapshot; avoid raw CSS/XPath.
- Never navigate to production without approval.
- Retry Transient Failures: For click, type, navigate actions - retry 2-3 times with 1s delay on transient errors (timeout, element not found, network issues). Escalate after max retries.
- Errors: transient→handle, persistent→escalate
