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

With no annotations, the description must carry the full behavioral burden. It usefully discloses ordering (newest first), the event taxonomy, and that each entry identifies the causing actor, but it says nothing about the operation being read-only, pagination/truncation behavior, or rate limits.

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 tight sentences with no waste; the resource and its ordering are front-loaded, followed by the intended use.

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?

With no output schema, the description compensates by describing the shape of returned entries (event, actor, timestamp ordering), enough for an agent to know what it gets back. It leaves return size/pagination behavior unaddressed, but the schema covers the count cap.

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 project_id and count are already fully documented in the schema, and the description's 'newest first' merely echoes the count parameter's own wording. Baseline 3 applies when the schema does the heavy lifting.

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 names a specific resource (a Scrapy Cloud project's activity log) and enumerates the event types it contains (jobs started/completed/cancelled, deployments), which no sibling offers. The verb is only implied by the noun phrase and tool name, so it falls just short of a crisp verb+resource statement.

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?

'Use it to answer who did what and when in a project' gives a clear scenario for selecting this tool over e.g. get_job_log or list_jobs. It does not name alternatives or state when not to use it, so it is context without exclusions.

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