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

Annotations already flag destructiveHint=true, readOnlyHint=false, idempotentHint=false and openWorldHint=true, so the safety bar is lower. The description adds a genuinely useful behavioral fact — that it updates in place rather than creating a new project — but it never explains what is overwritten (prior score or assessment history) or that a network fetch of the live URL occurs, leaving the destructive annotation unexplained.

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 the core behavior front-loaded and the documentation pointer trailing. Nothing is padded, though the second sentence is a URL pointer rather than substantive content.

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 two-parameter mutating tool with no output schema, the description promises a score comparison but never says what the response contains (old vs new score, delta) or what the reassessment replaces. Annotations cover the safety profile, so the gap is moderate rather than severe.

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 50%: the schema documents 'url' as an optional replacement HTTPS URL but leaves 'projectId' bare. The description mentions neither parameter, so it adds no meaning beyond the schema and fails to compensate for the undocumented required projectId.

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 uses a specific verb and resource ('Reassess a connected project') and adds a distinguishing scope note ('without creating a second project'), which separates it from assess_launch. It stops short of naming the sibling explicitly, so it is clear but not fully differentiated.

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?

'After changes' implies the trigger condition for using this tool, and the no-duplicate-project clause hints at why to prefer it over a fresh assessment. However, it never names assess_launch or states when a new assessment is preferable, so the guidance remains implied rather than explicit.

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