Clear Session Audit Log

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

Annotations already declare destructiveHint=true and idempotentHint=false, so the safety profile is known. The description adds the irreversibility detail ('cannot be undone') and the connection scope, which is modest value, but it does not say what exactly is erased or whether other callers on the connection are affected.

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 sentences, front-loaded with the action and followed by the blast radius. Nothing extraneous or padded.

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 zero-parameter destructive operation with annotations covering the safety profile and no output schema, the description supplies the essentials. A note on the retention/confirmation implications, and reconciling 'audit log' in the description with 'session log' in the name, would close the remaining gap.

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 to explain and the schema already declares an empty object with additionalProperties=false. Baseline of 4 applies; nothing is missing.

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?

States a specific verb and resource — 'Clear the audit log' — scoped to 'the current connection', which is more precise than the bare tool name. It does not, however, name its closest siblings (get_session_log, list_audit_logs) to make the read-vs-clear distinction explicit.

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 clear versus when to keep the log, no prerequisite or confirmation guidance, and no reference to the sibling read tools that an agent would naturally consider first. The destructive warning is a caution, not usage routing.

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