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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety and locality are covered. The description adds that this is an aggregate starting point rather than a filtered query, but says nothing about time scope for the non-'today' categories (how far back unpaid balances or parts delays go) or whether results are cached. With annotations carrying the safety profile, this is adequate but not rich.

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 short sentences, front-loaded with the contents and closed with the orientation cue. The telegraphic comma-list is efficient but slightly fragmented, making the four categories read as an unstructured run-on rather than a clean enumeration.

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 no-parameter, read-only aggregation tool with no output schema, enumerating the four result categories is exactly the information an agent needs to decide to call it. Nothing required for correct invocation 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?

There are zero parameters, so there is nothing for the description to disambiguate; the baseline of 4 applies. The description correctly implies no input is needed by presenting the tool as a fixed dashboard.

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 enumerates the concrete contents of the summary (today's jobs, unpaid accounts, jobs waiting on parts, tech pay owed), which tells an agent this is an aggregated office dashboard read. It is specific about content but never states the verb explicitly ('returns a summary of...'), so the action is inferred from the title rather than the text. It does distinguish itself from single-purpose siblings like list_jobs or tech_pay_report by spanning all of them.

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?

'Start here' gives a genuine orientation cue, implying this is the entry point before drilling into detail tools. However, no alternatives are named and no conditions for choosing it over what_did_i_miss, tech_pay_report, or list_jobs are stated. The routing signal is present but thin.

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