### ✅ Advanced DSL Features (NEW!)
**Implemented**: 2025-10-20
Major enhancements to DSL capabilities:
#### Subtask Attribute Inheritance
| 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
| 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
| 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
| 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
| 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
| 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`)
