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

No annotations are provided, so the description carries the full burden, and it does contribute one genuine behavioral fact not in the schema: results are returned newest-first. However, it never states that this is a safe read-only operation, says nothing about pagination behavior beyond the ordering, and gives no auth or scope notes.

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 with no filler, and the ordering constraint is front-loaded where an agent will see it 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?

For a simple two-parameter list tool with an output schema (which handles return-value explanation), the description covers purpose and ordering adequately. The gaps are the undocumented limit parameter and lack of read-only/auth framing, which are minor given the tool's simplicity.

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 only 50%: objective_id is documented as an 'Objective UUID' but limit has no description at all. The description implies which objective is queried ('an objective's status updates') but says nothing about limit, the default of 20, or the 1-100 range, so it does not compensate for the coverage gap.

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 ('an objective's status updates') plus an ordering guarantee ('newest first'), which clearly separates it from the mutating sibling memory_strategic_objective_status_post. It does not name that sibling explicitly, so sibling differentiation is implicit rather than stated.

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 when-to-use, when-not-to-use, or alternative-tool guidance. The agent must infer from the name alone that this is the read side of the status-update pair; no prerequisites or scoping conditions are given.

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