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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds two useful behavioral facts: the enumerated action states and that it reports 'what the last check saw', plus a 'Free' cost disclosure. It does not cover pagination or result shape, so it sits at a solid 3 against the annotation baseline.

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 short, front-loaded sentences with no padding; the content of the result is stated first. The 'Free.' fragment is terse and slightly cryptic but still informative.

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 no-required-param read tool this is mostly adequate: it says what is returned and the possible states. However, with no output schema and 0% schema coverage, the unexplained module filter and the vague 'what the last check saw' leave gaps an agent would want filled.

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 0%, so the description must carry parameter meaning. It echoes the state enum (CLAIMED/VERIFIED/FAILED), which is already structured data and earns no credit, while the module filter and its nine enum values are never explained. Filtering semantics remain undocumented.

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 conveys a clear resource — recorded actions with their states and last-check observations — so an agent understands this is a read/list tool. The verb is implicit ('Every recorded action'), and it does not distinguish itself from siblings like record_action or verify, but the resource is specific enough to act on.

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?

No when-to-use, when-not-to-use, or alternative is named. The trailing 'Free' hints at cost but gives no selection guidance relative to the many sibling query tools (record_action, verify, tracking_check).

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