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

Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=false, so the safety profile is covered. The description adds one genuinely useful non-obvious fact — that published pages survive the deletion — but omits irreversibility, permission requirements, and whether pages/revisions inside the project are cascaded away.

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?

Two short sentences with no filler; the primary action is front-loaded and the non-obvious side-effect caveat follows immediately. Nothing redundant with the title.

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?

Annotations carry the destructive/idempotent profile, so the description does not need to restate them. It is still thin for a destructive operation: no confirmation of what else is destroyed, no permission or recovery context, and the sole parameter's meaning is left implicit.

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 0% schema description coverage; the description never clarifies whether 'id' is a project identifier, slug, or name. For a single-identifier delete tool the convention is largely guessable, so the baseline 3 is appropriate rather than a penalty.

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 specific verb and resource ('Remove a saved project') and bounds the scope ('from this workspace'). The resource noun cleanly separates it from sibling delete tools such as delete_page, delete_guide, and delete_audience, so an agent can route without opening the schema.

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?

Usage is implied by the verb and scope, but there is no explicit when-to-use guidance, no mention of alternatives (e.g., save_project for modifying, get_project for reading), and no stated prerequisites or preconditions for deletion.

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