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

With no annotations and no output schema, the description carries the full behavioral burden and delivers little. It mentions state values and 'what the last check saw', but says nothing about permissions, scope (whose actions), result ordering, pagination, or result volume for what is presumably an unbounded listing.

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 state list is placed early. The dangling 'Free.' is contextual noise that is not integrated into the sentence structure, keeping this just short of a 5.

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 read tool with no annotations, no output schema, and two undocumented enum parameters, the description is too thin. An agent cannot tell what set of actions is returned, whether filters are ANDed, how results are ordered, or what 'last check' maps to in the output.

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?

Both parameters have 0% schema description coverage and the description only echoes the state enum values that already appear in the schema. It never explains the module enum or what filtering by module means, and with 0 required parameters it does not say whether omitting both returns everything.

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 identifies the resource (recorded actions) and its payload (state plus what the last check saw), which is more than a tautology. However, it never states a verb or retrieval scope, and it does nothing to separate itself from siblings like record_action, verify, or app_audit, which an agent could easily confuse with it.

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 guidance on when to call this versus record_action, verify, tracking_check, or app_audit. The trailing 'Free.' hints at a cost distinction but never says to prefer this tool on that basis, so the agent is left to infer the usage context entirely.

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