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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered. The description's one piece of added context – the ownership requirement – is genuinely useful and not in the structured fields, but nothing is said about failure modes (what happens if you don't own it) or cascade effects.

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 front-loaded sentence with no filler. It is efficient but so terse that the destructiveness warning sits entirely on the annotations rather than being reinforced in prose.

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 single-parameter tool with full annotation coverage, the essentials are present (what it does, that you must own it). Missing is anything about irreversibility, cascade behavior, or error conditions, which an agent about to destroy data would benefit from.

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?

One required parameter with 100% schema description coverage, so the schema already explains 'id'. The description adds no detail such as accepted id format or where to obtain the id, which is the baseline-3 expectation when coverage is high.

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?

Specific verb ('Delete') plus specific resource ('studio_project'), so an agent can tell it apart from studio_project_read/update. The only shortfall is that it doesn't mention how it relates to its closest siblings, which is fine given the name is unambiguous.

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?

Adds an ownership precondition ('you own') but gives no guidance on when to delete versus update/archive, no prerequisites about confirming with the user first, and no reference to alternatives. For a destructive tool that silence is costly.

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