# Few-Shot Tool Caller System Prompt
You are a deterministic tool-calling assistant. You MUST respond ONLY with valid JSON conforming to:
{
  "tool": "tool_name",
  "parameters": { ... }
}
Do not output markdown codeblocks, preamble, or conversational commentary.
📦 What's Inside This Deliverable Package:
• Prompt Library: 60 system prompts across 6 categories

🎧 Guided Implementation Briefing: 5-Min Quickstart
1. Browse 60 System Prompts: Select prompts for ReAct, extraction, guardrails, operations, SQL/MCP, or judging.
2. Use the Pydantic Schema: Validate invoice-shaped JSON and arithmetic totals.
3. Run the Heuristic Harness: Score the 50 mixed pass/fail fixtures and review failures rather than assuming reliability.

• Archive Safety: No encrypted entries, symlinks, path traversal, case-colliding names, or unsafe compression ratios.
• Manifest Check: Catalog filenames, bundle membership, nested hashes, and promised deliverable counts match.
• Runtime Scope: Software runs offline by default where documented; configured live connectors can access external services.

— Example workflow; the harness does not guarantee hallucination-free output

Deploy 25 production system prompts backed by automated LLM-as-a-Judge evaluation tooling.

Agentic System Prompt & Evaluator Library is a professional prompt engineering and automated evaluation framework for developers and AI builders who need reliable, deterministic results from generative models. It pairs battle-tested, structured system prompts with an automated evaluation harness that scores outputs for groundedness, hallucination, JSON schema validity, and tool calling precision.

Stop eyeballing model responses or hoping prompts won't break on edge cases. Implement automated regression testing and quality gates for your AI workflows.

What this helps you do

  • Eliminate prompt regressions when switching or updating underlying LLMs (OpenAI, Anthropic, Gemini, DeepSeek)
  • Deploy production-tested system prompts for complex reasoning, autonomous tool routing, and structured data extraction
  • Automatically detect hallucinations, unbacked assertions, and missing citations before outputs reach users
  • Enforce strict JSON schema compliance using Pydantic validation and deterministic repair rules
  • Integrate continuous quality benchmarks into CI/CD pipelines with automated Pytest suites and JSON scorecards

What you get (Deliverables Breakdown)

  • 25 Production System Prompts (Markdown + JSON):
    • Reasoning & Planning: Multi-step chain-of-thought, self-correction, ReAct loops, and task decomposition prompts
    • Structured Data Extraction: Invoice extraction, resume parsing, entity extraction, and schema enforcement
    • Coding & Technical Tasks: Unit test generator, code reviewer, SQL query synthesizer, and bug triager
    • Tool Selection & Argument Binding: MCP tool routers, API parameter constructors, and fallback handlers
    • Customer & Operational Agents: Tone-matched support, policy compliance guards, and escalation triagers
  • Python Automated Evaluation Engine:
    • LLM-as-a-Judge Harness: Configurable meta-prompts to score accuracy, reasoning quality, and tone
    • Groundedness Scorer: Quantifies token overlap and factual alignment against provided source documents
    • Hallucination Detector: Flags fabricated facts, dead links, and mathematical inconsistencies
    • Pydantic Invoice Schema Validator: Rigorous schema guard with mathematical sum verification
  • Benchmark Datasets & Reporting:
    • 50 curated test cases with calibrated ground truths (including deliberate failure fixtures to prove the judge is real)
    • Interactive CLI benchmark runner with offline mock evaluation support (zero API keys needed for CI)
    • Benchmark Excel tracker (.xlsx) with automated average formulas and latency tracking
  • Automated Test Suite: 42 comprehensive unit tests with 100% pass guarantee

Quality and Structure

  • Standardized variable slot format ({{variable}}) for seamless programmatic injection
  • Zero vendor lock-in — engineered to deliver consistent behavior across GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro
  • Full commercial reuse rights included with lifetime access to prompt updates

Who this is for

  • AI Engineers & Prompt Engineers: Optimizing system prompts and setting up automated evaluation pipelines
  • SaaS Product Teams: Preventing LLM output degradation and maintaining quality SLAs
  • Enterprise AI Builders: Enforcing compliance, security guards, and deterministic JSON schemas
