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

With no annotations, the description carries the full behavioral burden, and it does disclose one genuinely useful trait: results are ordered newest first. However, it says nothing about pagination behavior even though a cursor parameter exists, nor about whether results are scoped to the caller's visible projects.

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 sentence with zero filler; the resource and its ordering are front-loaded so an agent gets the essential fact immediately.

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?

An output schema exists, so return shape need not be explained, and the schema documents the cursor contract. The only real gap is the absence of any pagination note tying limit/cursor together into a paging workflow.

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 67%: cursor and project_id are documented in-schema, but limit is not. The description adds no parameter meaning beyond noting the newest-first ordering, which only loosely relates to limit/cursor. With middling coverage and a self-evident limit param, this is a baseline 3.

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 (List) and resource (a project's status updates), and clarifies the resource's meaning with '(health history)' plus the sort order. It does not explicitly name the sibling project_status_post as the write counterpart, but the list-vs-post distinction is self-evident from the names.

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 never says when to reach for this tool versus alternatives, nor does it mention prerequisites such as needing an existing project_id or any permission to read a project's health history. Usage is only inferable from the verb and resource.

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