validate_file

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint, so the safety profile is covered. Beyond that, the description says nothing about what "integrity" means (checksums, structural parse, branch/entry sanity), how failures are surfaced, or whether the check is a costly full scan of a potentially large file — meaningful gaps for a validation operation.

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?

Five words, front-loaded, with zero filler or repetition. It is terse to the point of under-specification, but nothing in the sentence is wasted.

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?

With no output schema, the description must explain what a successful versus failed validation returns (boolean, error list, exception), and it does not. Combined with the missing sibling differentiation and undefined notion of "integrity," an agent cannot predict the result shape or cost before calling.

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 a single required "path" parameter, so the schema already documents the input and a baseline 3 applies. The description adds only the implied constraint that the path should reference a ROOT file, with no detail on accepted path forms (local vs remote) beyond that.

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?

"Validate ROOT file integrity" gives a specific verb (validate) and resource (ROOT file), so the agent knows this checks a file rather than listing or reading it. It does not explicitly distinguish itself from the closest sibling, inspect_file, leaving the boundary between inspecting and validating to inference.

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 choose this over inspect_file, list_files, or read_branches, and no stated prerequisites (e.g., file must be closed, accessible, or local versus remote). The agent must guess the trigger condition for validation from the name alone.

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