AI-Augmented API Skill

Design LLM tool definitions, agentic workflows, and natural language API interfaces.


Anthropic Tool Use Definition

"query": {
"type": "string",
"description": "Search query keywords"
},
"category": {
"type": "string",
"enum": ["electronics", "clothing", "books", "home"],
"description": "Optional category filter"

"limit": { "type": "integer", "default": 10, "description": "Max results to return" }
},
"required": ["query"]
}
}

OpenAI Function Calling Definition

json
{
"type": "function",
"function": {
"name": "create_order",
"description": "Create a new order for a user. Use when the user wants to purchase a product. Always confirm product and quantity before calling.",
"parameters": {
"type": "object",
"properties": {
"product_id": { "type": "string", "description": "The product ID to order" },
"quantity": { "type": "integer", "minimum": 1, "description": "Quantity to order" },
"shipping_address": {
"type": "object",
"properties": {
"street": { "type": "string" },
"city": { "type": "string" },
"country": { "type": "string" }
},
"required": ["street", "city", "country"]
}
},
"required": ["product_id", "quantity", "shipping_address"]
}
}
}

MCP (Model Context Protocol) Tool Schema

json
{
"name": "get_build_status",
"description": "Get the status of a HyperExecute test job. Use when the user asks about test results, job status, or CI build outcomes.",
"inputSchema": {
"type": "object",
"properties": {
"job_id": { "type": "string", "description": "The HyperExecute job ID" }
},
"required": ["job_id"]
}
}
🔗 Real-World Integration — TestMu AI HyperExecute
Build MCP tools that let AI agents query and control test jobs via the HyperExecute API.

Tool Design Principles

  1. One tool = one action: Don't combine search + filter + sort into one tool. Split them.
  2. Description drives routing: The LLM picks tools from descriptions — be specific and include trigger phrases.
  3. Required vs optional: Only mark fields required if the API truly needs them.
  4. Enum for constrained values: Use enum instead of string for fixed-choice fields.
  5. Idempotent where possible: Prefer read tools over write tools for exploration.
  6. Confirm before destructive actions: Description should say "Always confirm with the user before calling."

Agentic Workflow Example

User: "Get me the status of my last 3 test builds"
Agent plan:
1. call list_jobs(limit=3, sort="created_at:desc")
→ returns [{id: "job_1", status: "passed"}, {id: "job_2", status: "failed"}, ...]
2. call get_job_details(job_id="job_2") // dig into the failed one
→ returns task breakdown, error logs
3. Synthesize: "Your last 3 builds: job_1 passed, job_2 failed (2 of 15 tasks failed on Chrome/Win10), job_3 passed."

Natural Language → API Mapping Table

Build this mapping for any domain:

Natural language intentAPI call
"Find hotels in Paris"GET /hotels/search?location=Paris
"Book a room for 2 nights"POST /bookings
"Cancel my reservation"POST /bookings/{id}/cancel
"Show my past orders"GET /orders?user=me&sort=date:desc
"Is the API working?"GET /health/ready

API-as-Plugin (OpenAPI → GPT Plugin / Tool)

Minimal ai-plugin.json:

json
{
"schema_version": "v1",
"name_for_human": "My API",
"name_for_model": "my_api",
"description_for_human": "Access my service's data and actions.",
"description_for_model": "Use this plugin to search, create, update and delete resources in My API. Always prefer specific endpoints over generic ones. Confirm destructive actions with the user first.",
"auth": { "type": "oauth" },
"api": { "type": "openapi", "url": "https://api.example.com/openapi.json" }
}
