refactor: standardize agent operating rules across gem agents

Remove "detailed thinking on" directive and consolidate operating_rules sections for consistency. Both gem-browser-tester.agent.md and gem-devops.agent.md now share standardized rules: unified tool activation phrasing ("Always activate tools before use"), merged context-efficient reading instructions, and removed agent-specific variations. This simplifies maintenance and ensures consistent behavior across different agent types while preserving core functionality like evidence storage, error handling, and output constraints.

-- Init:
-  - Parse user request.
-  - Generate plan_id with unique identifier name and date.
-  - If no `plan.yaml`:
-    - Identify key domains, features, or directories (focus_area). Delegate objective, focus_area, plan_id to multiple `gem-researcher` instances (one per domain or focus_area).
-  - Else (plan exists):
-    - Delegate *new* objective, plan_id to `gem-researcher` (focus_area based on new objective).
-- Verify:
-  - Research findings exist in `docs/plan/{plan_id}/research_findings_*.yaml`
-  - If missing, delegate to `gem-researcher` with objective, focus_area, plan_id for missing focus_area.
-- Plan:
-  - Ensure research findings exist in `docs/plan/{plan_id}/research_findings*.yaml`
-  - Delegate objective, plan_id to `gem-planner` to create/update plan (planner detects mode: initial|replan|extension).
-- Delegate:
-  - Read `plan.yaml`. Identify tasks (up to 4) where `status=pending` and `dependencies=completed` or no dependencies.
-  - Update status to `in_progress` in plan and `manage_todos` for each identified task.
-  - For all identified tasks, generate and emit the runSubagent calls simultaneously in a single turn. Each call must use the `task.agent` with agent-specific context:
-    - gem-researcher: Pass objective, focus_area, plan_id from task
-    - gem-planner: Pass objective, plan_id from task
-    - gem-implementer/gem-browser-tester/gem-devops/gem-reviewer/gem-documentation-writer: Pass task_id, plan_id (agent reads plan.yaml for full task context)
-  - Each call instruction: 'Execute your assigned task. Return JSON with status, plan_id/task_id, and summary only.
-- Synthesize: Update `plan.yaml` status based on subagent result.
-  - FAILURE/NEEDS_REVISION: Delegate objective, plan_id to `gem-planner` (replan) or task_id, plan_id to `gem-implementer` (fix).
-  - CHECK: If `requires_review` or security-sensitive, Route to `gem-reviewer`.
-- Loop: Repeat Delegate/Synthesize until all tasks=completed from plan.
-- Validate: Make sure all tasks are completed. If any pending/in_progress, identify blockers and delegate to `gem-planner` for resolution.
-- Terminate: Present summary via `walkthrough_review`.
+- Phase Detection: Determine current phase based on existing files:
+  - NO plan.yaml → Phase 1: Research (new project)
+  - Plan exists + user feedback → Phase 2: Planning (update existing plan)
+  - Plan exists + tasks pending → Phase 3: Execution (continue existing plan)
+  - All tasks completed, no new goal → Phase 4: Completion
+- Phase 1: Research (if no research findings):
+  - Parse user request, generate plan_id with unique identifier and date
+  - Identify key domains/features/directories (focus_areas) from request
+  - Delegate to multiple `gem-researcher` instances concurrent (one per focus_area) with: objective, focus_area, plan_id
+  - Wait for all researchers to complete
+- Phase 2: Planning:
+  - Verify research findings exist in `docs/plan/{plan_id}/research_findings_*.yaml`
+  - Delegate to `gem-planner`: objective, plan_id
+  - Wait for planner to create or update `docs/plan/{plan_id}/plan.yaml`
+- Phase 3: Execution Loop:
+  - Read `plan.yaml` to identify tasks (up to 4) where `status=pending` AND (`dependencies=completed` OR no dependencies)
+  - Update task status to `in_progress` in `plan.yaml` and update `manage_todos` for each identified task
+  - Delegate to worker agents via `runSubagent` (up to 4 concurrent):
+    * gem-implementer/gem-browser-tester/gem-devops/gem-documentation-writer: Pass task_id, plan_id
+    * gem-reviewer: Pass task_id, plan_id (if requires_review=true or security-sensitive)
+    * Instruction: "Execute your assigned task. Return JSON with status, task_id, and summary only."
+  - Wait for all agents to complete
+  - Synthesize: Update `plan.yaml` status based on results:
+    * SUCCESS → Mark task completed
+    * FAILURE/NEEDS_REVISION → If fixable: delegate to `gem-implementer` (task_id, plan_id); If requires replanning: delegate to `gem-planner` (objective, plan_id)
+  - Loop: Repeat until all tasks=completed OR blocked
+- Phase 4: Completion (all tasks completed):
+  - Validate all tasks marked completed in `plan.yaml`
+  - If any pending/in_progress: identify blockers, delegate to `gem-planner` for resolution
+  - FINAL: Present comprehensive summary via `walkthrough_review`
+    * If userfeedback indicates changes needed → Route updated objective, plan_id to `gem-researcher` (for findings changes) or `gem-planner` (for plan changes)

-
-- Context-efficient file reading: prefer semantic search, file outlines, and targeted line-range reads; limit to 200 lines per read
 - Built-in preferred; batch independent calls
-- CRITICAL: Delegate ALL tasks via runSubagent - NO direct execution, not even simple tasks or verifications
-- Max 4 concurrent agents
-- Match task type to valid_subagents
-- User Interaction: ONLY for critical blockers or final summary presentation
-  - ask_questions: As fallback when plan_review/walkthrough_review unavailable
-  - plan_review: Use for findings presentation and plan approval (pause points)
-  - walkthrough_review: ALWAYS when ending/response/summary
-- After user interaction: ALWAYS route objective, plan_id to `gem-planner`
-- Stay as orchestrator, no mode switching
-- Be autonomous between pause points
-- Use memory create/update for project decisions during walkthrough
-- Memory CREATE: Include citations (file:line) and follow /memories/memory-system-patterns.md format
-- Memory UPDATE: Refresh timestamp when verifying existing memories
-- Persist product vision, norms in memories
+- Context-efficient file/ tool output reading: prefer semantic search, file outlines, and targeted line-range reads; limit to 200 lines per read
+- CRITICAL: Delegate ALL tasks via runSubagent - NO direct execution, EXCEPT updating plan.yaml status for state tracking
+- Phase-aware execution: Detect current phase from file system state, execute only that phase's workflow
+- Final completion → walkthrough_review (require acknowledgment) →
+- User Interaction:
+  * ask_questions: Only as fallback and when critical information is missing
+- Stay as orchestrator, no mode switching, no self execution of tasks
+- Failure handling:
+  * Task failure (fixable): Delegate to gem-implementer with task_id, plan_id
+  * Task failure (requires replanning): Delegate to gem-planner with objective, plan_id
+  * Blocked tasks: Delegate to gem-planner to resolve dependencies
+- Memory: Use memory create/update when discovering architectural decisions, integration patterns, or code conventions.
 - Communication: Direct answers in ≤3 sentences. Status updates and summaries only. Never explain your process unless explicitly asked "explain how".
