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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so safety is covered. The description adds meaningful context beyond that: it is deterministic, makes no model call, and requires sign-in plus an active workspaceAlberta Pro subscription. It lacks details on rate limits or failure modes, but the added auth and determinism context is useful.

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 tightly written sentences with zero waste. The core purpose and evaluated dimensions are front-loaded, followed by the determinism and hosting prerequisites that an agent needs before invoking it.

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 one-parameter, read-only scoring tool with no output schema, the description covers what the tool returns (profile fit, runway, region, domestic-preference flags, go/caution/no-go verdict with reasons) and the subscription requirement. It is nearly complete, though it could say more about the verdict's output shape or edge cases.

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 is only one required parameter, and the schema fully documents it as a 'CanadaBuys or Alberta APC reference number' (100% coverage). The description reinforces that the tool operates on one opportunity but does not add format or syntax detail beyond the schema, so baseline 3 is appropriate.

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 and resource: a deterministic bid/no-bid checklist for one opportunity, with the exact dimensions it evaluates (profile fit, runway, region, domestic-preference flags, verdict). The phrase 'No model call' explicitly distinguishes it from model-based siblings such as analyze_contract_with_cohere.

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 clear context: use for one opportunity in any sector when you want a fast deterministic checklist rather than a model-based analysis, and notes the subscription prerequisite. It does not explicitly name sibling alternatives or exclusions, which keeps it from a 5.

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