Overview

Create MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. The quality of an MCP server is measured by how well it enables LLMs to accomplish real-world tasks.

Working discipline

These bias toward caution over speed — use judgment on trivial tasks.

• Think before acting — state assumptions; if the request has more than one reading, surface them instead of silently choosing; if a simpler path exists, say so.
• Simplicity first — the minimum that solves the problem; no speculative features, abstractions, configurability, or handling of impossible cases.
• Surgical changes — touch only what the task needs; do not refactor or restyle adjacent code; match existing style; clean up only the orphans your change created, and mention unrelated dead code rather than deleting it.
• Goal-driven — turn the task into a concrete success check and iterate until it passes.
