Refactor agent communication structure across multiple skills to unify message handling

- Updated SKILL.md files in team-testing, team-ui-polish, team-uidesign, team-ultra-analyze, team-ux-improve, and team-visual-a11y to replace 'items' with 'message' for agent spawning.
- Enhanced role assignment and task context messaging for clarity and consistency.
- Introduced new agents: cli_roadmap_plan_agent, exploration_planner, requirements_analyst, and validation_archivist with detailed developer instructions for parallel development cycles.
- Implemented timeout settings for wait_agent() calls in workflow-plan and workflow-tdd-plan skills to improve execution reliability.

+## Progress Milestone Protocol
+
+Report progress via `mcp__ccw-tools__team_msg` at natural phase boundaries. This enables coordinator status dashboards and timeout forensics.
+
+### Milestone Reporting
+
+At each phase boundary, report progress:
+
+```javascript
+mcp__ccw-tools__team_msg({
+  operation: "log",
+  session_id: "<session_id>",
+  from: "<task_id>",
+  to: "coordinator",
+  type: "progress",
+  summary: "[<task_id>] <brief phase description> (<pct>%)",
+  data: {
+    task_id: "<task_id>",
+    role: "<role>",
+    status: "in_progress",
+    progress_pct: <0-100>,
+    phase: "<what just completed>",
+    key_info: "<most important finding or decision>"
+  }
+})
+```
+
+### Role-Specific Milestones
+
+| Role | ~30% | ~60% | ~90% |
+|------|------|------|------|
+| analyst/researcher | Context loaded | Core analysis done | Verification complete |
+| writer/drafter | Sources gathered | Draft written | Self-review done |
+| planner | Requirements parsed | Plan structured | Dependencies validated |
+| executor/implementer | Context loaded | Core changes done | Tests passing |
+| reviewer/tester | Scope mapped | Reviews/tests done | Report compiled |
+
+### Blocker Reporting
+
+Report blockers immediately (don't wait for next milestone):
+
+```javascript
+mcp__ccw-tools__team_msg({
+  operation: "log",
+  session_id: "<session_id>",
+  from: "<task_id>",
+  to: "coordinator",
+  type: "blocker",
+  summary: "[<task_id>] BLOCKED: <brief description>",
+  data: {
+    task_id: "<task_id>",
+    role: "<role>",
+    blocker_detail: "<what is blocking>",
+    severity: "high|medium",
+    attempted: "<what was tried>"
+  }
+})
+```
+
+### Completion Report
+
+After `report_agent_job_result` / Phase 5 SendMessage, also log:
+
+```javascript
+mcp__ccw-tools__team_msg({
+  operation: "log",
+  session_id: "<session_id>",
+  from: "<task_id>",
+  to: "coordinator",
+  type: "task_complete",
+  summary: "[<task_id>] Complete: <one-line result>",
+  data: {
+    task_id: "<task_id>",
+    role: "<role>",
+    status: "completed",
+    progress_pct: 100,
+    artifact: "<artifact_path>",
+    files_modified: []
+  }
+})
+```
+
+### Overhead Rule
+
+- Max 3-4 milestone messages per task (context loaded, core work done, verification complete, plus blockers)
+- Each message < 200 chars summary
+- Do NOT report every minor step — only natural phase boundaries
+
+---
+
 ## Phase 5: Report + Pipeline Notification (Built-in)
 
 After Phase 4 completes, determine Phase 5 variant (see Execution Flow for decision table).

+- Topologically-sorted task sequence
+- Each task: id (T1-Tn), title, type, scope, inputs, outputs, convergence, depends_on, parallel_group
+- Inputs must come from preceding task outputs or existing resources
+- Tasks in same parallel_group must be truly independent
+
+## Output
+Write decomposition results to session folder as specified in task assignment.
+Create issues via ccw issue create for each task/layer.
+Generate roadmap.md with full plan structure.
