bulk-upsert

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions 'bulk insert or update' and 'upsert operations,' which implies mutation capabilities, but doesn't address critical behaviors like authentication requirements (though the schema hints at apiKey), error handling, performance characteristics, rate limits, or what happens on conflicts. The description is too sparse for a mutation tool with zero annotation coverage.

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?

The description is extremely concise with two sentences that directly state the tool's function and key feature. Every word earns its place, and it's front-loaded with the core purpose. No unnecessary details 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?

Given the complexity of a bulk mutation tool with 4 parameters, 50% schema coverage, no annotations, and no output schema, the description is incomplete. It lacks details on authentication, error handling, return values, performance implications, and usage context. For a tool that modifies data, this is inadequate.

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 description coverage is 50% (2 of 4 parameters have descriptions). The description adds some context by mentioning 'CSV or JSON file' and 'unique key,' which loosely relates to 'filePath' and 'upsertKey' parameters, but doesn't provide detailed semantics like file format specifics, key constraints, or how upsert works. It partially compensates for the coverage gap but not fully.

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 purpose: 'Bulk insert or update data from CSV or JSON file. Supports upsert operations with a unique key.' It specifies the verb (bulk insert/update), resource (data), and format (CSV/JSON), but doesn't explicitly differentiate from siblings like 'run-raw-sql' or 'get-table-schema' which serve different purposes.

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 provided on when to use this tool versus alternatives. The description mentions upsert operations but doesn't specify scenarios where bulk-upsert is preferred over individual operations or other data import methods. There's no mention of prerequisites, limitations, or comparison with sibling tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
