Import Tracker worklog record

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

Annotations already carry the mutation profile (readOnly=false, idempotent=false, destructive=false), so the bar is lower. The description still adds value beyond them: the admin-only authorization requirement, the side effect of retaining original authorship timestamps, and the note that the endpoint responds with a JSON array (important because no output schema exists).

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 zero filler. The differentiating behavior and the admin-only constraint are front-loaded, and the return-shape note is appended economically.

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 2-parameter nested-body tool with no output schema, the description covers the essentials: what it does, the authorization gate, and the response shape (JSON array). It lacks pagination/error or duplicate-handling notes, but nothing critical to a correct invocation is missing.

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% and every body field (start, duration, createdAt, createdBy, comment) is individually documented, so the baseline of 3 applies. The description adds no parameter-level meaning beyond the schema, but none is needed.

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 gives a specific verb+resource ('Import a worklog record') and adds a differentiating qualifier — it preserves the original author and timestamps — which separates it from the sibling tracker_worklog_create. It stops short of explicitly naming that sibling, so it is clear but not fully sibling-differentiated.

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?

It states the administrative prerequisite ('admin-only'), which is real usage guidance. However, it never states when to choose this over tracker_worklog_create or tracker_worklog_update; the 'preserve original author/timestamps' phrasing only implies the migration use case rather than saying it.

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