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

Annotations already declare readOnlyHint=true and idempotentHint=true, so safety and repeatability are covered. The description adds the team-level scope, which is useful, but leaves 'recent actions' undefined — no time window, no pagination or volume limits — and repeats return contents that the output schema already supplies.

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 sentences, zero filler, and the resource plus scope are front-loaded before the return summary. Every clause earns its place.

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-only tool with annotations covering the safety profile and a full output schema, the description is nearly sufficient — scope and contents are both stated. The remaining gap is the undefined 'recent' window, which affects how an agent interprets and reports the data.

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 nothing for the description to disambiguate and the baseline of 4 applies. The stated team scope correctly signals that no user or team identifier needs to be passed.

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 a specific verb ('Get') and resource ('autonomous agent activity') plus the scope ('authenticated user's team'), and enumerates what comes back (enabled agents, recent actions, per-agent stats, pending approvals). That enumeration distinguishes it from neighbors like get-person-activity-tool, get-ai-adoption-tool, and get-my-insights-tool, though it never names an alternative explicitly.

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 reach for this tool versus the many overlapping reporting siblings (get-ai-adoption-tool, get-mcp-adoption-tool, get-team-overview-tool, get-my-status-tool). The only guidance is the implicit 'for the authenticated user's team' scoping; no exclusions or prerequisites are given.

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