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

Annotations already declare readOnlyHint and destructiveHint=false, so the safety profile is covered. The description still adds genuinely useful context beyond them: it discloses that non-applicable Ontario streams are labeled, and explicitly states that workspaceAlberta does not apply for funding or decide eligibility, which sets an important authority boundary.

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?

The opening clause is well front-loaded, but the bulk of the description is a long run-on enumeration of specific program names that is more marketing copy than decision-relevant information for an agent selecting a tool. The final disclaimer earns its place; the program list largely does not.

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?

There is no output schema, so the description should describe what a caller gets back. It hints at an 'applies section' only indirectly through the limit parameter and never explains sections, ranking, or result shape, leaving a meaningful gap for a tool whose value is in structured matching results.

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 fully documents the six parameters including the nested profile object. The description adds essentially nothing about parameter behavior, only the incidental phrase 'applies section' which loosely relates to the limit parameter. Baseline 3 applies when the schema carries this weight.

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 (a read-only catalog of industrial and tariff support programs) and enumerates the covered programs, so its domain is unmistakable against siblings that deal in contracts and tenders. There is a mild verb mismatch: the tool name says 'match' while the description frames it as a 'catalog', leaving some ambiguity about whether matching/ranking is performed or just listing.

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?

'For any Canadian business' and 'an Alberta firm can ask about' imply the audience, and the Ontario-only labeling note clarifies scope. But there is no explicit when-to-use statement, no exclusions relative to sibling tools (e.g., find_alberta_opportunities), and no stated prerequisites, so the agent must infer placement in the workflow.

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