# Gemini Api Integration

Orchestrates intelligent skill selection and execution for gemini api integration 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

```python
def build_gemini_request(
    task_description: str,
    system_prompt: str,
    model: str = "gemini-1.5-pro",
    max_tokens: int = 2048,
    temperature: float = 0.7
) -> Dict:
    """Construct a validated Gemini API request payload.
    
    Applies Law 2 (Parse at boundary) by validating inputs against Gemini's constraints.
    Returns a new dict structure representing the API call.
    """
    if not task_description or not task_description.strip():
        raise ValueError("Task description cannot be empty")
        
    supported_models = ["gemini-pro", "gemini-1.5-pro", "gemini-1.5-flash"]
    if model not in supported_models:
        raise ValueError(f"Unsupported model: {model}. Use one of {supported_models}")
        
    clean_prompt = task_description.strip()
    if len(clean_prompt) > 30000:
        clean_prompt = clean_prompt[:30000]
        
    request_payload = {
        "contents": [
            {"role": "user", "parts": [{"text": clean_prompt}]}
        ],
        "generationConfig": {
            "maxOutputTokens": max_tokens,
            "temperature": temperature,
            "topK": 40,
            "topP": 0.95
        },
        "safetySettings": [
            {"category": "HARM_CATEGORY_HARASSMENT", "threshold": "BLOCK_MEDIUM_AND_ABOVE"},
            {"category": "HARM_CATEGORY_HATE_SPEECH", "threshold": "BLOCK_MEDIUM_AND_ABOVE"}
        ]
    }
    
    if system_prompt:
        request_payload["system_instruction"] = {"parts": [{"text": system_prompt}]}
        
    return request_payload
```


### Pattern 2: Execution with Fallback

```python
def execute_gemini_call(
    request_payload: Dict,
    api_key: str,
    fallback_model: str = "gemini-1.5-flash",
    max_retries: int = 2
) -> Dict:
    """Execute a Gemini API call with domain-specific fallback chain.
    
    Implements Law 4 (Fail Fast/Loud) for API errors.
    Fallback: 1. Retry with exponential backoff -> 2. Switch to faster/cheaper model -> 3. Return cached/error
    """
    import time
    import requests
    
    model_name = request_payload["generationConfig"].get("model", "gemini-1.5-pro")
    url = f"https://generativelanguage.googleapis.com/v1beta/models/{model_name}:generateContent"
    headers = {"Content-Type": "application/json"}
    
    for attempt in range(max_retries + 1):
        try:
            response = requests.post(
                url,
                headers=headers,
                params={"key": api_key},
                json=request_payload,
                timeout=30
            )
            
            if response.status_code == 200:
                return {
                    "success": True,
                    "model_used": model_name,
                    "candidates": response.json().get("candidates", []),
                    "usage_metadata": response.json().get("usageMetadata", {}),
                    "attempts": attempt + 1
                }
                
            if response.status_code == 401:
                raise ValueError("Invalid Gemini API key")
            if response.status_code == 429:
                retry_after = int(response.headers.get("Retry-After", 2 ** attempt))
                time.sleep(retry_after)
                continue
                
        except requests.exceptions.RequestException as e:
            if attempt == max_retries:
                return _apply_gemini_fallback(request_payload, api_key, fallback_model)
            time.sleep(2 ** attempt)
            
    return {"success": False, "error": "All retries exhausted", "fallback_triggered": True}
```

### 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
- 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
