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

Annotations already cover readOnly/openWorld/non-destructive, and the description adds genuinely new operational context: it is a hosted call requiring sign-in and an active subscription, and it names the underlying model. It does not mention latency, per-call cost/quotas, or how long an analysis is cached, which would be the remaining useful disclosures.

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 sentences, front-loaded with the action and followed by the gating prerequisite. No filler, no restating of the title.

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, non-destructive analysis tool with 100% schema coverage and no output schema, the description covers what the tool produces and what it requires to run. Minor gap: no hint of response length/format despite exposing a `max_tokens` control, and no guidance on the shared-public-endpoint vs subscriber-key modes for this specific call.

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% and the required `reference` parameter plus the nested `profile` object are fully documented in the schema, including the override semantics of the inline profile. The description adds nothing about parameters beyond the schema, so the baseline 3 applies.

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 (review/analyze), a specific resource (a CanadaBuys tender), the engine used (Cohere Command A+), and the shape of the output (fit, risks, next steps). An agent can distinguish this from lookup siblings like get_contract_details or get_opportunity_details, though the boundary with bid_no_bid_scorecard (also a fit assessment) is not addressed.

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 real precondition ('sign-in and an active workspaceAlberta Pro subscription required'), which is actionable usage context. However, it never says when to choose this over bid_no_bid_scorecard, classify_tender, or check_cohere_status, so the selection logic is left to inference.

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