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

Annotations already cover safety (readOnly/idempotent/non-destructive), and the description still adds real substance: notices are returned critical-first, carry a stable id/kind/message/action URL, and dismissed notices are filtered out. It even explains the operational consequence of a disconnected tracker (missions cannot start or report back), which helps the agent prioritize escalation to a human.

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?

Three sentences, front-loaded with the purpose and severity ordering. The return-shape sentence and the dismissal-exclusion sentence each carry distinct information, and the closing line lands the call-to-action.

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 input schema, no output schema and annotations already covering the safety profile, the description supplies everything an agent needs: what the notices represent, ordering, returned fields, exclusion rule, and when to check. Nothing material is missing despite the lack of a documented response schema.

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 the baseline is 4. The description correctly implies no caller-side filtering, noting that dismissal state (not a parameter) governs exclusion from results.

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?

Specific verb (read) + resource (workspace notices) with scope and ordering (critical first) made explicit. The two example notice kinds (rejected tracker connection, credits running out) make it unmistakable against siblings like get_billing, get_setup_progress or dismiss_notice.

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?

Gives a clear proactive directive ('Check it before dispatching work'), which is exactly the trigger context an agent needs. It does not explicitly name alternatives (e.g. go to get_billing instead for billing detail), so 5 is not warranted.

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