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

Annotations already declare the safe read-only, idempotent, non-destructive profile. The description adds useful context beyond that by listing the returned fields and stating the cross-tool timezone convention, though it does not discuss error or permission-failure behavior.

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?

It is front-loaded with "Start here" and then gives a compact enumeration of the returned information. The timezone note is short and directly relevant, with no wasted sentences.

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 does a good job covering the main return values and the important timezone convention for other tools. It could be slightly more complete by mentioning exact field names, workspace identifiers, or return structure, but it is sufficient for an agent to call a zero-parameter read 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?

The tool takes no parameters, so there is no parameter semantics to explain. The description appropriately focuses on what the call returns rather than on nonexistent inputs.

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 workspace context resource and enumerates exactly what it returns: workspace name, timezone, plan limits, monthly post usage, approval requirement, and permissions. No sibling tool covers this workspace-level scope, so an agent can distinguish it immediately.

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?

"Start here" gives clear initial-call guidance, and the timezone note tells the agent how to interpret times in other tools. It does not specify when not to use it or name alternatives, but no sibling appears to overlap this purpose.

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