Agents of this workspace

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description still adds real value: it discloses the per-agent payload (activity plus a track record over created/executed/signal-recorded/outcome/overdue) and the important limitation 'Counts only, no ranking.' It stops short of disclosing pagination or exact return shape.

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 dense sentence, front-loaded with the resource and its metrics, with the endpoint appended. Slightly run-on with the colon list, but every clause carries information and nothing is wasted.

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 only one optional parameter, no output schema, and annotations covering safety, the description adequately conveys what the tool returns and its counts-only scope. It could say more about granularity or ordering, but it is sufficient for correct invocation.

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%; the single 'days' parameter is fully documented in the schema ('Window in days, default 30'). The description adds no extra meaning about the window, so the baseline 3 applies.

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?

States the resource (every agent of this workspace) and enumerates the specific activity metrics returned: created, executed, signal recorded, outcomes, overdue. This is a clear verbless-but-specific retrieval description that an agent can act on, though it never explicitly differentiates itself from siblings like forbiz_me or forbiz_state.

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?

Usage is only implied: the roster-plus-tally framing suggests it is an overview tool, and 'Counts only, no ranking' hints at its scope. There is no explicit when-to-use statement and no named alternative for getting per-action or per-user detail.

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