Conductor Implement

Conductor Implement

Orchestrates intelligent skill selection and execution for conductor implement workflows. Applies the 5 Laws of Elegant Defense to guide data naturally through the orchestration pipeline, preventing errors before they occur. Selects optimal skills based on multi-factor scoring including text similarity, historical performance, and system availability.

TL;DR Checklist

• Parse all inputs at boundary before processing (Law 2)
• Handle edge cases with early returns at function top (Law 1)
• Fail immediately with descriptive errors on invalid states (Law 4)
• Return new data structures, never mutate inputs (Law 3)
• Implement minimum 2-level fallback chain for all skill executions
• Log all skill selections with context for full audit trail
• Validate skill metadata and dependencies before selection
• Update confidence scores after each execution for learning

When to Use

Use this skill when:

• Orchestrating multi-step workflows that require skill delegation
• Implementing adaptive skill routing based on confidence scores
• Building fallback mechanisms for failed skill executions
• Creating intelligent task decomposition and parallel execution
• Designing skill dependency graphs with automatic resolution
• Implementing skill selection with historical performance weighting
• Building agent systems that need to self-organize around tasks

When NOT to Use

Avoid this skill for:

• Direct task execution without orchestration needs - use individual skills instead
• High-frequency trading scenarios where latency must be minimized - the selection overhead may be prohibitive
• Simple linear workflows without branching or fallback requirements
• Cases where skill metadata is unavailable or unreliable

Core Workflow

1. Parse and Analyze Request - Extract intent, entities, and constraints from user input. Checkpoint: All required parameters must be present and in valid format before proceeding.

2. Score Available Skills - Calculate match scores using multi-factor algorithm:

   • Text similarity between request and skill triggers
   • Historical success rate for similar tasks
   • Skill availability and health status
   • Required dependencies and their availability

   Checkpoint: Skip to fallback if no skill scores above threshold.

3. Select Optimal Skill - Choose skill with highest score that meets minimum confidence. Checkpoint: Verify skill has not been disabled or deprecated.

4. Execute with Fallback - Run skill execution wrapped in retry and fallback logic. Checkpoint: Log all execution attempts for audit trail.

5. Return or Fallback - Either return successful result or apply fallback chain:

   • Retry with adjusted parameters
   • Try alternative skill from related-skills
   • Defer to human operator for critical tasks

   Checkpoint: Record outcome with timing and confidence metadata.

Implementation Patterns

Pattern 1: Skill Selection Logic

class ConductorOrchestrator:
    """Domain-specific orchestrator for conductor-implement workflows."""
    
    def score_and_select(self, request: str, registry: list[dict]) -> dict | None:
        """Multi-factor skill selection with dependency validation and audit logging."""
        if not request or not registry:
            raise ValueError("Request and skill registry are required")
        
        # Law 2: Parse at boundary before scoring
        parsed = self._parse_request(request)
        best_match = None
        best_score = 0.0
        
        for skill in registry:
            # Law 1: Early exit for disabled/deprecated skills
            if skill.get("status") in ("disabled", "deprecated"):
                continue
            
            # Multi-factor scoring: text similarity + historical success + availability
            text_score = self._cosine_similarity(parsed["intent"], skill["triggers"])
            history_score = skill.get("success_rate", 0.0)
            availability_score = 1.0 if skill.get("available") else 0.0
            
            # Weighted composite score with configurable thresholds
            composite = (text_score * 0.5) + (history_score * 0.3) + (availability_score * 0.2)
            
            if composite > best_score and composite >= 0.7:
                # Law 3: Return new structure, never mutate registry
                best_match = {
                    "skill_id": skill["id"],
                    "score": round(composite, 3),
                    "dependencies": skill.get("requires", []),
                    "confidence": composite,
                    "selection_context": parsed["entities"]
                }
                best_score = composite
                
        # Audit log selection decision
        self._log_selection(best_match, parsed)
        return best_match

Pattern 2: Execution with Fallback

class ConductorOrchestrator:
    # ... (previous method) ...
    
    def execute_with_fallback_chain(self, selected: dict, context: dict) -> dict:
        """Domain-specific execution with 2-level fallback and confidence tracking."""
        skill_id = selected["skill_id"]
        attempts = 0
        
        # Fallback chain: Primary -> Alternative -> Human Escalation
        fallback_targets = [
            {"id": skill_id, "type": "primary"},
            {"id": selected.get("alternative_skill"), "type": "alternative"},
            {"id": "human_operator", "type": "escalation"}
        ]
        
        for target in fallback_targets:
            attempts += 1
            try:
                # Law 4: Fail fast on invalid state
                if not self._validate_context(context, target["id"]):
                    raise InvalidStateError(f"Context mismatch for {target['id']}")
                    
                result = self._invoke_skill(target["id"], context)
                
                # Update confidence based on execution outcome
                self._update_confidence_score(target["id"], success=True)
                
                return {
                    "status": "success",
                    "executed_skill": target["id"],
                    "result": result,
                    "attempts": attempts,
                    "audit": self._log_execution(target["id"], attempts)
                }
                
            except TransientError:
                continue # Proceed to next fallback level
            except InvalidStateError as e:
                # Law 4: Fail loud, don't patch bad data
                self._log_execution(target["id"], attempts, error=str(e))
                raise ExecutionFailedError(f"Invalid state at {target['id']}: {e}") from e
                
        # All fallbacks exhausted
        self._log_execution("fallback_exhausted", attempts)
        raise ExecutionFailedError(f"All fallback chains failed for {skill_id}")

MUST DO

• Always validate skill metadata before selection (Early Exit)
• Implement fallback chain with at least 2 levels (Fallback Skill + Human)
• Log all skill selections with full context for auditability
• Return new data structures instead of mutating inputs (Atomic Predictability)
• Fail immediately with descriptive errors on invalid states
• Update confidence scores after each execution for adaptive routing
• Reference code-philosophy (5 Laws of Elegant Defense) in all logic

MUST NOT DO

• Select skills based on a single factor (e.g., only confidence score)
• Disable fallback mechanisms "temporarily" - this creates fragile systems
• Skip validation of skill dependencies before execution
• Return partial results - either complete success or clear failure
• Use magic numbers for confidence thresholds - make them configurable
• Cache skill selections without considering context changes

TL;DR Checklist

• Parse all inputs at boundary before processing (Law 2)
• Handle edge cases with early returns at function top (Law 1)
• Fail immediately with descriptive errors on invalid states (Law 4)
• Return new data structures, never mutate inputs (Law 3)
• Implement minimum 2-level fallback chain for all skill executions
• Log all skill selections with context for full audit trail
• Validate skill metadata and dependencies before selection
• Update confidence scores after each execution for learning

TL;DR for Code Generation

• Use guard clauses - return early on invalid input before doing work
• Return simple types (dict, str, int, bool, list) - avoid complex nested objects
• Cyclomatic complexity < 10 per function - split anything larger
• Handle null/empty cases explicitly at function top (Early Exit)
• Never mutate input parameters - return new dicts/objects
• Fail fast with descriptive errors - don't try to "patch" bad data
• Reference code-philosophy laws in comments for complex logic
• Include timing and confidence metadata in all return values

Output Template

When applying this skill, produce:

1. Selected Skills - List of skill names with confidence scores
2. Selection Rationale - Why each skill was chosen (match score, history, availability)
3. Execution Plan - Order of execution with dependencies
4. Fallback Strategy - Which fallback skills will be tried and in what order
5. Risk Assessment - Any potential failure points and their impact
6. Timing Estimates - Expected latency including fallback scenarios

Constraints

MUST DO

• Parse user request into structured task specifications before dispatching to downstream agents
• Implement a state machine for each conductor phase with explicit entry/exit conditions and transition logs
• Validate implement outputs against expected schema before proceeding to the next orchestration step
• Log every orchestration decision including rationale, selected strategy, and confidence scores for auditability
• Maintain a task queue with priority ordering — critical path items execute first during resource contention

MUST NOT DO

• Do not allow a single failed agent task to silently terminate the entire workflow — implement per-step fallbacks
• Avoid circular delegation patterns where Agent A delegates to B which delegates back to A without termination condition
• Never bypass the validation step for implement results even if timing is critical — correctness supersedes speed
• Do not use shared mutable state between parallel agent executions — use message-passing or immutable data transfer
• Avoid hardcoding agent selection rules; parameterize them and load from configuration for runtime flexibility
