### ✅ Advanced DSL Features (NEW!)

**Implemented**: 2025-10-20

Major enhancements to DSL capabilities:

#### Subtask Attribute Inheritance

| Feature | Status | Implementation |
|---------|--------|----------------|
| Parent → child inheritance || `schema.rs` inherit_from_parent() |
| Agent inheritance || Default to parent agent |
| Context injection cascade || inject_context propagation |
| Error handling inheritance || on_error strategy |
| Priority inheritance || Parent priority cascade |
| Loop control inheritance || Loop settings propagation |

**Tests**: 8 comprehensive inheritance tests passing

#### Workflow Context Injection

| Feature | Status | Implementation |
|---------|--------|----------------|
| Opt-in context injection || `inject_context` field in TaskSpec |
| Output file path in context || Agents know where to save results |
| Token usage optimization || Only inject when needed (default: false) |
| Workflow state visibility || Completed tasks summary |

**Tests**: 3 context injection tests passing

#### Variable Interpolation in DoD

| Feature | Status | Implementation |
|---------|--------|----------------|
| Variable support in paths || `${workflow.variable}` syntax |
| Pattern interpolation || Variables in search patterns |
| FileExists criteria || Interpolated paths |
| FileContains criteria || Interpolated paths & patterns |
| FileNotContains criteria || Interpolated paths & patterns |
| Regex pattern support || Full regex in file checks |

**Tests**: 32 executor tests passing including regex patterns

#### CLI File Input Support

| Feature | Status | Implementation |
|---------|--------|----------------|
| File-based descriptions || `-f/--file` flag added |
| Optional arguments || Description or file required |
| Modification from file || Update workflows via file |
| Error validation || Ensure input provided |

---

### ✅ Definition of Done Permission Intelligence

**Implemented**: 2025-10-20

Intelligent permission detection and guidance system for DoD failures:

#### Features

| Feature | Status | Implementation |
|---------|--------|----------------|
| Permission issue detection || `executor.rs` detect_permission_issue() |
| Enhanced feedback with hints || `executor.rs` enhance_feedback_with_permission_hints() |
| Auto-elevation support || `schema.rs` auto_elevate_permissions field |
| Contextual guidance || Tailored feedback based on detection |

#### How It Works

When DoD criteria fail:
1. **Detect**: Analyze output for permission keywords and file failures
2. **Enhance**: Add targeted hints to feedback
3. **Guide**: Tell agent about available permissions (if auto_elevate=true)
4. **Retry**: Agent receives clear guidance on next attempt

**Benefits**:
- ✅ Faster DoD resolution with permission clarity
- ✅ Reduces retry failures from permission confusion
- ✅ Configurable via `auto_elevate_permissions` flag
- ✅ Backward compatible (default: false)

**Code Changes**:
- Modified: `src/dsl/schema.rs` (1 field added)
- Modified: `src/dsl/executor.rs` (~100 lines added)
- Functions: `detect_permission_issue()`, `enhance_feedback_with_permission_hints()`

---

### ✅ DSL Generator Auto-Fix System

**Implemented**: 2025-01-19

A robust auto-fix retry system for DSL workflow generation that automatically detects and corrects errors:

#### Features

| Feature | Status | Implementation |
|---------|--------|----------------|
| YAML extraction error handling || `nl_generator.rs` lines 112-130 |
| Parsing error detection & retry || `nl_generator.rs` lines 133-155 |
| Validation error correction || `nl_generator.rs` lines 158-190 |
| Multi-attempt retry logic || Up to 3 attempts with detailed feedback |
| Error context preservation || Failed YAML + error messages sent to AI |
| Progress feedback || User-visible retry attempt messages |

#### How It Works

When `periplon-executor generate` encounters an error:
1. **Attempt 1**: Generate workflow from description
2. **On Error**: Capture failed YAML + error message
3. **Retry**: Submit both to AI with fix instructions
4. **Validate**: Check parsing and semantic correctness
5. **Repeat**: Up to 3 attempts total

**Benefits**:
- ✅ Handles `ConditionSpec` parsing errors
- ✅ Fixes invalid agent references automatically
- ✅ Corrects circular dependency issues
- ✅ Resolves tool name typos
- ✅ Clear user feedback during retry process

**Code Changes**:
- Modified: `src/dsl/nl_generator.rs` (~140 lines added)
- Functions: `generate_from_nl()`, `modify_workflow_from_nl()`
- Max retries: 3 attempts (configurable via `MAX_VALIDATION_RETRIES`)

## Known Limitations

### Current Implementation

1. ~~**No Dependency Resolution**: Tasks with dependencies not fully resolved (Phase 3)~~**RESOLVED**
2. ~~**No Lock Files**: Cannot guarantee reproducible builds (Phase 3)~~**RESOLVED**
3. ~~**No Task Groups**: Cannot bundle related tasks (Phase 4)~~**RESOLVED**
4. **No Registry Support**: Only local and git sources (Phase 5) - **Next Priority**
5. **No Publishing Tools**: Cannot easily share tasks (Phase 6)

### Planned Resolution

Remaining limitations (Phases 5 & 6) will be addressed in upcoming development cycles.
