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

Annotations already establish read-only, idempotent, and non-destructive behavior, so the bar is lower. The description adds value by stating the result is the full, permanent record for a published day and by pinning the expected date format (YYYY-MM-DD).

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 deliver the core behavior, date format, and primary use case without fluff. The most important scoping phrase ('one dated Executive Brief in full') is front-loaded.

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?

The description handles purpose, ordering relative to list_executive_notes, and date format, and an output schema is present. However, with 0% input-schema coverage, the unexplained scope and market parameters leave a real gap for an agent selecting values or understanding the tool's breadth.

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 description coverage is 0%, so the description needs to compensate for all three parameters. It implicitly covers as_of via 'dated (YYYY-MM-DD)' but says nothing about scope or market, which appear only as unannotated names with defaults.

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 names a specific resource ('one dated Executive Brief in full'), requires a date, and frames it as the permanent daily record. It differentiates itself from list_executive_notes by saying this is the follow-up read for a specific day, and from the many siblings by highlighting the dated-retrieval scope.

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?

The description explicitly gives two triggers: use after list_executive_notes to read a specific day, and use it for retroactive questions like 'what did we say about X back then?'. This clearly routes an agent toward this tool and away from list_executive_notes.

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