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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows this is a safe read operation. The description adds the phrase 'privacy-filtered project metadata,' which hints at a behavioral trait (data is filtered for privacy), but it is too vague to be genuinely useful. No contradiction with annotations.

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?

The description is short, but its brevity is not a virtue because it sacrifices clarity. The phrase 'hosted get project health' is awkward and likely a typo or artifact, and the sentence structure is confusing. It is concise in word count but not in communicative efficiency.

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 read tool with no output schema and 0% parameter coverage, the description is incomplete. It does not explain what 'health' means, what data is returned, how privacy filtering affects results, or how this differs from get_project_status. The annotations cover safety but not the operational semantics an agent needs to invoke the tool correctly.

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 description coverage is 0%, so the description carries the full burden of explaining parameters. It fails to do so: it does not explain what projectId, sessionId, or executionId mean, how they relate, or which are required. The description's mention of 'project metadata' only weakly maps to projectId and does not clarify the optional sessionId and executionId parameters.

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 'Read hosted get project health using privacy-filtered project metadata' is confusing and tautological. It repeats the tool name ('get project health') and the phrase 'hosted get project health' is grammatically awkward and unclear. It does not clearly state what the tool does or what 'health' means in this context, and it does not distinguish it from siblings like get_project_status or get_project_sync_status.

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?

The description provides no guidance on when to use this tool versus alternatives. It does not mention that get_project_status or get_project_sync_status might be more appropriate for specific needs, nor does it state any prerequisites or context for calling it. The only hint is 'privacy-filtered project metadata,' which is vague and not actionable.

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