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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is known. The description adds nothing beyond that: it never says whether deletion is permanent, whether checkpoints or restore_checkpoint can recover the file, or whether folders are removed recursively — all critical for a destructive 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?

A single short sentence with zero filler, front-loaded with the verb. It is concise to the point of under-specification, however, and the phrase "file or folder" creates cost-free ambiguity rather than earning its place.

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 an irreversible destructive tool with no output schema and only half its parameters documented, the description omits the details an agent most needs: recoverability, recursive folder behavior, and how it differs from delete_folder and delete_items. It is not adequate for the tool's risk level.

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 only 50%: projectId is documented ("Project id from list_projects") but path has no description, and the tool description adds no meaning about path format, whether it is relative to the project root, or how directories are addressed. With a coverage gap, the description should compensate but does not.

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?

States a concrete verb and resource ("Deletes a file or folder") scoped to a project, so the operation is immediately identifiable. However, saying it deletes "a file or folder" blurs the boundary with the sibling delete_folder tool, so an agent cannot fully distinguish the two from the description alone.

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 when-to-use guidance, no exclusion such as "use delete_folder for directories," and no mention of the sibling delete_items or delete_folder alternatives despite both existing. The agent must guess which deletion tool applies to directories.

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