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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description does add one real behavioral fact not in the annotations — that private entries are included — and notes privacy settings come back, but it omits pagination/default-limit behavior beyond what the schema says.

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?

One short sentence with no waste, but it is a sentence fragment that front-loads a possessive noun phrase rather than the action. Brevity here reflects under-specification as much as conciseness.

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 partially compensates by naming what is returned (entries and privacy settings). However, it leaves the limit default/pagination behavior and the relationship between the two returned datasets unexplained for a two-parameter listing tool.

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% (limit is documented as 'max 100', api_key with its header alternative), so the schema carries parameter meaning. The description adds nothing further about parameters, making 3 the correct baseline.

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 identifies the resource (recent work log entries plus work privacy settings) but is a noun fragment with no verb, so it never literally says 'list/retrieve'. It is distinguishable from siblings like list_my_projects and log_work, but the reader must infer the action.

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 statement of when to use this rather than log_work, set_work_privacy, or list_my_projects, and no prerequisites or exclusions. Usage is only implied by the name and the mention of the returned data.

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