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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed-world scope, so safety is covered. The description adds one genuinely useful behavioral detail — that results are 'stored'/'latest', i.e. a cached snapshot rather than a live recomputation — but says nothing about freshness, refresh cadence, or what happens when no audit exists.

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?

A single compact sentence with no filler, and the key qualifier ('latest stored') is front-loaded. It is a noun phrase rather than a clause, which costs a little immediate actionability but wastes nothing.

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 parameters, no output schema, and full annotation coverage, the definition is nearly sufficient for invocation. However, it never defines what an 'audit finding' contains or what the letter-grade scale means, which is the main thing an agent must know to interpret 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?

The tool takes zero parameters, so there is no parameter semantics for the description to carry; the baseline of 4 applies. The schema is trivially complete and the description introduces no confusing parameter-like language.

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 (latest stored audit findings) and its payload (letter grades and scores), so an agent can tell what comes back. It stops short of a verb and never distinguishes itself from the similarly-shaped sibling get_latest_report, leaving overlap unresolved.

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?

There is no statement of when to call this tool, no prerequisites, and no mention of alternatives such as get_latest_report or get_performance_summary. The agent must infer that this is the grades-only read path.

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