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

Annotations already cover read-only, idempotent, non-destructive, and closed-world behavior. The description adds useful behavioral context by explaining that the result is a deterministic 'no AI' brief with labelled decision-card lines and confidence-labelled timeline links, though it does not mention auth or rate-limit behavior.

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 key point is front-loaded: it returns one SAM.gov contract notice. The sentence is dense and uses long parenthetical lists, but the detail is largely justified because there is no output schema and the return shape is non-trivial.

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?

With no output schema, the description must explain what comes back, and it does: decision card contents, timeline elements with confidence labels, and file-version diffs. Combined with the fully documented single parameter and annotations, this is complete enough for an agent to call it correctly.

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 notice_id format and sources, including the SAM.gov URL pattern and run_plan rows. The description repeats those sources but adds no additional syntax or semantic detail beyond the schema, making the baseline score 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?

The description clearly states it retrieves one SAM.gov contract notice and enumerates the brief contents: decision card, timeline, and file-version changes. It is specific about the resource and verb, but it does not explicitly distinguish itself from sibling search or planning tools such as run_plan.

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?

Usage is implied by 'One SAM.gov contract notice' and by saying notice_id comes from run_plan contract_opportunities rows or a SAM.gov notice URL. However, there is no explicit guidance on when to use this tool versus search tools or run_plan, and no exclusions or prerequisites are stated.

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