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 safety profile is covered. The description adds only one behavioral detail beyond that: results are drawn from "privacy-filtered project metadata," which hints at data scoping but says nothing about what health signals (sessions, sync, findings) are included.

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 short sentence is appropriately sized, but the wording "Read hosted get project health" is redundant and awkwardly assembled, and the modifier "using privacy-filtered project metadata" trails rather than front-loads the useful detail.

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-only, idempotent tool with full annotation coverage, a complete output schema absent, the description is nearly sufficient — an agent knows it is a safe read. What remains missing is what "health" comprises and how it differs from sibling status tools, a gap more relevant to selection than invocation.

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 100%, so the baseline is 3. The description adds nothing about projectId, sessionId, or executionId semantics, and notably the schema reuses the same projectId-oriented description for sessionId and executionId, which the description does not clarify.

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 garbled phrasing "Read hosted get project health" still conveys a read of project health, so the resource and verb are recoverable. But it offers no differentiation from siblings like get_project_status, get_project_sync_status, or get_dashboard_widget_state, leaving ambiguity about which health/status view this is.

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 indication of when to call this versus the many adjacent status/health tools in the sibling list. No prerequisites, no exclusions, no named alternative are given; the agent must infer selection.

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