zulip_status

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and network access are covered. The description adds the default-resolution chain for topic selection and the shape of the returned line, but says nothing about authentication requirements, failure modes, or how recent the "recent mentions" window is, which matter for an open-world read.

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 compact sentences with no filler, and the output content is front-loaded before the defaulting rule. The opening phrase "One line:" is slightly cryptic but functions as a useful format hint.

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 and no annotations beyond read-only and open-world, the description must convey returns and defaults, which it does at a summary level. It still leaves gaps on the meaning of the "age" and "recent mentions" windows and on prerequisites for reaching the server, so an agent could call it but not fully predict the result.

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 coverage is 0% and both parameters are nullable with no descriptions, so the description carries the burden; it does so by explaining that topic falls back to the path's repo and branch and then to the server's folder. That fallback chain is exactly the meaning an agent needs to decide whether to pass path or topic, though path's own semantics are only implicit.

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 states the tool returns a one-line topic summary: message count, last sender, age, and recent bot mentions. That is a specific resource and content set, but there is no clear verb ("status" is not clarified as a read/report action), and nothing explicitly separates it from zulip_mentions or zulip_topics, which overlap with the mention and topic elements.

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 explicit when-to-use or when-not-to-use guidance, and no sibling is named as an alternative. The defaulting chain for topic selection is useful context but is a parameter behavior, not usage guidance.

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