Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

Scored across 8 tools
Each tool has a clearly distinct purpose with no overlap: checking type compatibility, finding interfaces, getting package types, getting project info, looking up types, reinitializing the indexer, validating interface implementation, and validating type usage. The descriptions make it easy for an agent to select the right tool without confusion.
The naming follows a consistent verb_noun pattern (e.g., check_type_compatibility, find_interfaces, get_package_types) with one minor deviation: 'lookup_type' uses 'lookup' instead of 'look_up' or 'get', but it still fits the overall style. The pattern is predictable and readable throughout.
With 8 tools, the count is well-scoped for a TypeScript definitions server. Each tool serves a specific, useful function in the domain of type checking and project management, with no redundancy. This number allows comprehensive coverage without being overwhelming.
The tool set covers core TypeScript definition workflows well, including type lookup, compatibility checks, interface handling, project info, and validation. A minor gap is the lack of tools for modifying or generating types (e.g., create_type or update_definition), but agents can work around this with the provided tools for most common tasks.
