# Task Board — Milestone T3: Feature Expansion

**Submilestone:** T3 (Custom plugins, workflow templates, audit, advanced features)

| ID | Scope | Status | Branch | Verification |
|----|-------|--------|--------|--------------|
| T3.1 | Custom skill plugins: load user-defined skills from plugin registry (not just pi clone) | [ ] | `task/T3.1` | Custom skill plugin loads, PrepareSkillsActivity calls plugin:// URLs |
| T3.2 | Workflow templates: save/load orchestrator config as YAML templates (not CLI flags only) | [ ] | `task/T3.2` | Load template `templates/golang-project.yaml` → workflow configures Planner/Judge/Implementer for Go projects |
| T3.3 | Task dependency graph: specify task order (T0.2 must complete before T0.3 can start) | [ ] | `task/T3.3` | Board supports `depends_on: [T0.1]` field, orchestrator respects ordering |
| T3.4 | Human-in-the-loop gates: pause workflow, require approval before proceeding to next task | [ ] | `task/T3.4` | Workflow waits for `approve-task` signal, Judge verdict is final (can't auto-retry after user approval) |
| T3.5 | Custom Judge implementations: swap default Judge for domain-specific validator (e.g., security auditor) | [ ] | `task/T3.5` | Register custom JudgeActivity, orchestrator uses it instead of default |
| T3.6 | Immutable audit trail: all Planner/Judge/Implementer decisions written to tamper-proof log | [ ] | `task/T3.6` | Audit log signed with per-workflow key, verification prevents tampering |
| T3.7 | Workflow composition: nest OrchestratorWorkflows (one orchestrator dispatches child orchestrators) | [ ] | `task/T3.7` | Multi-level task hierarchy: T0 milestone → T0.a/T0.b sub-milestones, each with own orchestrator |
| T3.8 | Integration with external task systems: import tasks from Linear, GitHub Issues, JIRA | [ ] | `task/T3.8` | Load board from GitHub Issues API, update issues with task completion status |

## Submission Criteria
All T3.1–T3.8 marked `[x]` → submilestone complete → squash-merge `task/T3.*` to main.
