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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is fully covered. The description adds value beyond that: the data comes from Atlassian's official status page and includes official incident updates plus component-level health, and it discloses a cost of 1 credit, which is operationally useful.

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?

Front-loaded with the purpose, then scope, then return content, then cost. Two clauses ('project management tools, issue tracking, and developer workflows') are largely redundant expansions of 'Jira' and could be trimmed without losing routing value.

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 parameterless, read-only status reader with no output schema, the description covers source, subject matter, and what kind of data comes back (incident updates, component health). Refresh cadence or whether it returns an overall up/down flag is unstated, but nothing essential to a correct call 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?

Zero parameters, so baseline 4 applies; there is nothing for the description to clarify about inputs and it doesn't waste words pretending otherwise.

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 ('monitor'/'check') and resource ('status of Jira Software and related Atlassian cloud services'), which distinguishes it from the many sibling status tools (github_status, cloudflare_status, slack_status) by naming the vendor and product family. It doesn't explicitly say 'for Atlassian products only' but the naming makes the routing clear enough.

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?

It gives a use context ('check for outages affecting project management tools, issue tracking, and developer workflows') but no explicit when-to-use/when-not guidance or named alternatives. An agent must infer it should pick this over github_status or zoom_status purely from the product name.

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