Agent Manager Skill
Orchestrates intelligent skill selection and execution for agent manager skill 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
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.
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.
Select Optimal Skill - Choose skill with highest score that meets minimum confidence. Checkpoint: Verify skill has not been disabled or deprecated.
Execute with Fallback - Run skill execution wrapped in retry and fallback logic. Checkpoint: Log all execution attempts for audit trail.
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
def route_task_to_agent(
task: TaskRequest,
agent_registry: List[AgentMetadata],
min_capability_score: float = 0.75
) -> Optional[AgentMetadata]:
"""Route a task to the most capable available agent based on domain expertise and current load.
Domain logic: Matches task domain tags against agent capabilities,
applies load balancing, and validates agent state before selection.
"""
if not task.domain or not task.payload:
raise ValueError("Task must specify a domain and contain a payload")
# Parse task requirements into normalized capability vectors
required_capabilities = _normalize_domain_tags(task.domain)
scored_agents = []
for agent in agent_registry:
if agent.status != "AVAILABLE":
continue
capability_match = _calculate_capability_overlap(required_capabilities, agent.capabilities)
load_penalty = agent.current_load / agent.max_capacity
adjusted_score = capability_match * (1.0 - load_penalty)
if adjusted_score >= min_capability_score:
scored_agents.append({
"agent_id": agent.id,
"score": adjusted_score,
"domain_match": capability_match,
"estimated_latency_ms": agent.avg_response_time * (1 + load_penalty)
})
if not scored_agents:
return None
# Sort by score descending, then by latency ascending
scored_agents.sort(key=lambda x: (-x["score"], x["estimated_latency_ms"]))
return scored_agents[0]
Pattern 2: Execution with Fallback
def execute_agent_task_with_routing(
task: TaskRequest,
selected_agent: AgentMetadata,
fallback_agents: List[AgentMetadata],
max_routing_attempts: int = 2
) -> ExecutionResult:
"""Execute task on selected agent with domain-aware fallback routing.
Domain logic: Handles agent-specific execution protocols,
implements tiered fallback routing (specialist -> generalist -> human),
and captures execution telemetry for confidence scoring.
"""
execution_context = _build_execution_context(task, selected_agent)
attempts = 0
while attempts <= max_routing_attempts:
try:
# Execute using agent-specific protocol
response = yield_to_agent(selected_agent, execution_context)
# Validate response structure and domain compliance
validated_result = _validate_agent_response(response, task.domain)
return ExecutionResult(
success=True,
agent_id=selected_agent.id,
payload=validated_result,
confidence=validated_result.confidence_score,
routing_attempts=attempts
)
except AgentTimeoutError:
attempts += 1
if attempts > max_routing_attempts:
break
# Fallback: route to next available agent in tier
selected_agent = _get_next_fallback_agent(selected_agent, fallback_agents, attempts)
if not selected_agent:
break
execution_context = _update_context_for_agent(execution_context, selected_agent)
except DomainValidationError as e:
# Fail fast on invalid domain state
raise ExecutionError(f"Domain validation failed: {e}") from e
# All routing attempts exhausted
return ExecutionResult(
success=False,
agent_id=selected_agent.id if selected_agent else None,
error="Routing chain exhausted",
confidence=0.0,
routing_attempts=attempts
)
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

Constraints
MUST DO
- Define clear input/output contracts for every step in the orchestration flow with explicit validation
- Implement structured logging at each stage capturing context, inputs, outputs, timing, and errors
- Build in fallback paths: if the primary strategy fails, degrade gracefully to a simpler approach
- Validate all preconditions before starting — do not proceed if required resources or permissions are missing
MUST NOT DO
- Do not create deep nesting of orchestration steps (>5 levels) — flatten workflows where possible
- Avoid silent failure modes: every step must either succeed, fail explicitly, or escalate to a higher handler
- Never use shared mutable state between parallel workflow branches — communicate via immutable messages only
- Do not hardcode execution order when the dependency graph naturally determines it; derive order from explicit dependencies
