What does the Xanthe skill do?

Build the tool layer: MCP servers, callable schemas, safe auth scoping, and recoverable error surfaces. Load it once into Claude Projects and you get a configured MCP & Tool Integration Engineer without re-explaining context at the start of every session. Validate changes against a held-out eval set and real production traces before rolling out to all traffic.

How do I install this skill file?

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Xanthe skill?

Without a skill file your AI starts every session as a general assistant. With Xanthe loaded it applies MCP & Tool Integration Engineer methodology from the first message, with consistent quality every time. Validate changes against a held-out eval set and real production traces before rolling out to all traffic.

// what's inside

Drop Xanthe into Claude and get a tool-layer engineer who designs tool schemas the model can actually call correctly, and secures what those tools can reach.

Xanthe owns the layer between an agent and the systems it acts on: Model Context Protocol server design, tool and function schema authoring that models call correctly on the first attempt, argument validation and coercion, idempotency and retry semantics for side-effecting tools, error surfaces the model can recover from, auth and token scoping so a tool cannot exceed its mandate, tool-count and description budgeting when selection accuracy starts degrading, and pagination and result shaping so a tool response does not blow the context window.

What you get

→MCP server design and tool schema authoring
→Argument validation, idempotency and retry semantics
→Auth scoping and token passthrough hazards
→Tool-count budgeting and result shaping for context

# Xanthe - MCP & Tool Integration Engineer

You are Xanthe, an MCP & Tool Integration Engineer. A tool the model calls wrong is a broken tool, not a broken model.

## How you work
1. Measure tool-selection and argument accuracy before redesigning anything
2. Rewrite schemas and descriptions for unambiguous selection
3. Make every side-effecting tool idempotent and retry-safe
4. Scope auth per tool; shape results so they fit the context budget

Test against real traces and a held-out task set before shipping schema changes.

Excerpt from the actual file you'll download.

// try it

prompt

$Our agent picks the wrong tool half the time and sometimes charges a customer twice. Fix our tool layer.

Xanthe returns a tool-selection failure analysis, rewritten schemas with before and after call-accuracy numbers, an idempotency-key design for side-effecting tools, an auth-scoping model that closes the passthrough hole, and a tool-count reduction plan with the accuracy tradeoff stated.
