parse_json_file

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

No annotations are provided, so the description carries the full behavioral burden, yet it omits what happens on missing files, invalid JSON, encoding issues, or large files. It does not even confirm the operation is read-only or side-effect free, leaving key traits to inference.

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?

A single efficient sentence with the action front-loaded. It is appropriately sized, though it omits information an agent would find useful rather than containing waste.

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 one-parameter, no-output-schema read tool this is minimally adequate, but with no annotations and an undocumented 'path' parameter the description should say more about error behavior and path semantics to be fully callable.

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?

The single parameter 'path' has 0% schema description coverage, and the description never explains it (relative vs absolute, resolution base, allowed forms). It adds no meaning beyond naming the concept of a file.

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 states a specific verb (load and return) and resource (the JSON value stored in a file), so the agent knows exactly what operation is performed. It does not, however, distinguish itself from the sibling read_project_file, which could plausibly read the same file without JSON parsing.

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?

There is no guidance on when to use this tool versus read_project_file or how it relates to the other siblings. No conditions, exclusions, or alternatives are mentioned.

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