import_json_file

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

No annotations are provided, so the description carries the burden. It explains what the tool does and parameter roles, but does not disclose whether import is additive or destructive, what happens on failure, or any file size limits. Core behavior is covered, but side effects and error handling are omitted.

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 brief (four sentences plus list), front-loads the core purpose, and uses a clear structure. Every sentence adds value without repetition or fluff.

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 5 parameters, no output schema, and no annotations, the description covers purpose, format support, and parameter details. It lacks mention of return value or side effects (e.g., whether data is appended or replaced). Considering complexity, it is mostly complete but misses output context.

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 0%, but the description provides full parameter details in an Args section: purpose, required/optional status, and default values. This adds complete meaning beyond the schema, which only lists names and types.

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 imports messages from JSON files, specifies supported formats (arrays, JSON-lines, wrapped objects), and lists example data sources (Google Chat, Hangouts, LinkedIn). It distinguishes from siblings by focusing on generic JSON import rather than platform-specific formats.

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?

The description implies use for JSON files, especially those from common services, but does not explicitly exclude other formats like CSV (handled by import_csv_file) or state when not to use this tool. It provides context but lacks explicit alternatives or exclusion criteria.

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