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

Annotations already declare destructiveHint=true, so safety is structurally disclosed. The description adds nothing about irreversibility, whether data is recoverable, required project state, or permission needs, and the "detach/delete" ambiguity leaves the actual consequence of the call unclear.

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?

It is a single short, front-loaded phrase with no filler, but that is brevity by omission rather than by discipline; the sentence is under-specified for a destructive tool.

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 destructive, one-parameter operation with no output schema, the definition should say what is destroyed, whether it is reversible, and how to recover. None of that is present, so an agent cannot predict the outcome beyond the destructive flag.

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% and the single project_id property already explains the "or use session from use_project" fallback. The description contributes no additional parameter guidance, which is the baseline expectation when the schema is complete.

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 names a verb and resource ("Detach/delete the project database"), so the target is identifiable. But the slash conflates two operations with very different consequences, and it does not distinguish this from sibling delete_project or explain its relation to attach_database.

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 statement of when to use this versus attach_database, delete_project, or delete_file. The agent must infer scope and prerequisites entirely from the sibling list.

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