Changes observed during successful MCP inspections.
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, but the description adds no behavioral context beyond confirming it is an ingestion/write operation. It does not describe side effects, idempotency, permissions, or what happens to existing data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with the main purpose and a clear parameter instruction. Every word earns its place; no fluff or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple one-parameter tool with no output schema, the description covers the essential purpose and parameter. However, it lacks any indication of return values, post-ingestion behavior, or cautions about the destructive nature beyond the annotations. Adequate but with clear gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, with the 'source' enum already documenting the values. The description repeats the enum values and maps them to data types ('religious' = historic religious properties, 'aahs' = African American historic sites) which adds some meaning, but does not go beyond the schema's baseline.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function: ingesting Philadelphia public records (landmarks, historic religious properties, African American historic sites) into the lilo system. The verb 'ingests' is specific and distinguishes this write operation from sibling read/search tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is given on when to use this tool versus alternatives. The instruction 'Pass source: all, landmarks, religious, or aahs' is parameter guidance, not usage context. No mention of exclusions or how this relates to read-only search tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
