Polar Privacy Audit

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

Annotations already declare this a safe read-only, idempotent, non-destructive, closed-world operation. The description adds genuine value beyond that by committing to a redaction guarantee ('without revealing secret values') and enumerating the inspected surfaces, which matters for a security-sensitive audit tool.

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 front-loaded sentence leads with the return verb and the security caveat, with no filler. Every clause carries scope information.

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?

An output schema exists, so return-value explanation is not required, and rich annotations cover the safety profile. What remains thin is routing guidance against overlapping sibling tools, otherwise the definition is complete for a read-only audit call.

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 single response_format parameter (markdown/json, default markdown) is undocumented in both the schema and the description. The description never mentions output format options, so it fails to compensate for the coverage gap even though the enum is fairly self-explanatory.

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 gives a specific verb ('Return') and an enumerated resource ('local privacy, cache, token-path and env-presence posture'), so an agent knows exactly what surface it inspects. It does not, however, differentiate itself from overlapping siblings such as polar_cache_status or polar_data_inventory, which likely return related posture data.

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 explicit when-to-use guidance, no prerequisites, and no mention of alternatives like polar_cache_status (cache focus) or polar_connection_status. Usage is only vaguely implied by the audit framing, leaving the agent to guess how this differs from the neighboring status tools.

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