verify_file_sha256

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

With no annotations, the description must carry the full behavioral burden. It only states that the file is verified against a digest, but does not disclose what happens on mismatch, whether the operation is read-only, or any side effects (e.g., logging). The 'dedicated workspace' constraint is a small addition but insufficient for complete transparency.

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 a single, front-loaded sentence with no unnecessary words. It clearly communicates the core action and scope in a compact manner.

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 lack of annotations and output schema, the description is too sparse. It does not explain the return value on success/failure, error handling for non-existent files or invalid digests, or what 'dedicated workspace' means in practice. This leaves critical gaps for an agent to use the tool correctly in a real workflow.

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 description does not mention the parameters 'file' or 'expectedSha256' at all. With 0% schema description coverage, the agent is left without guidance on how to specify the file path (relative vs absolute) or how to format the digest (though the schema provides a regex pattern). The description completely fails to compensate for the schema's lack of explanations.

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 action (verify) on a specific resource (one file under the dedicated workspace) against an expected SHA-256 digest. It clearly distinguishes itself from sibling tools by focusing on file integrity verification rather than mutation, disassembly, or emulator control.

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 about when to use this tool versus alternatives like run_project_verification or nds_mutation_verify. The description implies usage for SHA-256 file checks but does not mention exclusions, prerequisites, or situations where another tool would be more appropriate.

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