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

Annotations already cover the safety profile (readOnlyHint, destructiveHint=false, openWorldHint), so the description's contribution is the auth/subscription requirement and the note that it runs on a hosted Cohere Command A+ model. That is real operational context beyond the annotations, though it doesn't cover latency, rate limits, or failure modes.

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 tight sentences: the first states the action and outputs, the second states the access prerequisite. Front-loaded and free of filler.

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 read-only analysis tool with full schema coverage and no output schema, the description covers what it does, what it returns conceptually, and the access requirement. Only the omission of alternatives/usage routing keeps it from being fully complete.

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 100%, so the schema already documents all five parameters, including the nested profile object and its fields. The description adds no syntax or format detail beyond what the schema provides, which is the expected baseline.

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?

Names a specific verb (review/analyze), a specific resource (CanadaBuys tender), and the concrete outputs (fit, risks, next steps), which separates it from generic summarizers like summarize_contracts. It does not explicitly name or contrast a sibling tool, so it falls short of the top band.

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 gives a prerequisite ('sign-in and an active workspaceAlberta Pro subscription required') but no guidance on when to choose this over siblings such as bid_no_bid_scorecard or get_contract_details. There are no when-not conditions or named alternatives.

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