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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety and scope are covered structurally; the description's 'connected to this Sendhour workspace' reinforces the non-open-world scoping. Beyond that it discloses nothing about return shape, whether disconnected/expired accounts are included, or ordering.

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 short sentences with the resource stated first and the follow-up usage hint second. No filler, no redundancy, and the key information is front-loaded.

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 zero-parameter read tool with no output schema, the definition covers what is returned (connected social accounts) and why it matters (ids feed other tools). A note on whether account metadata or status is included would close the remaining gap, but nothing essential to 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?

The tool takes zero parameters, so there is no parameter semantics to explain and the baseline of 4 applies. Nothing in the description contradicts or misleads about the empty schema.

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 and resource: 'list' the 'social accounts connected to this Sendhour workspace', so an agent knows exactly what it retrieves. No sibling tool overlaps with account listing, so explicit differentiation isn't required, though it omits any hint of what fields each account carries.

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 the ids with the other tools' implies this is a prerequisite/discovery step for tools that act on accounts, which is a useful contextual cue. However, it never states when to call this versus, for example, get_credits or get_analytics, nor any preconditions or alternatives.

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