Clear recorded sequential-thinking history for one session or all sessions.

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

No annotations are provided, so the description carries the full behavioral burden for what is clearly a destructive operation. It never states that clearing is irreversible, whether an in-progress thinking session is affected, or whether confirmation/permissions are required — only the verb 'Clear' implies data loss.

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 with no filler; the scope qualifier comes at the end but the core action leads. It is efficient, though it duplicates the title almost verbatim, so brevity comes at the cost of added 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?

For a destructive tool with no annotations, no output schema, and zero required parameters, the description is too thin. It omits irreversibility, default behavior when neither parameter is supplied, and any return/confirmation semantics an agent needs to call it safely.

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 100%, so the schema already documents 'session_id' and 'all_sessions'; baseline is 3. The description's 'one session or all sessions' loosely mirrors the two parameters but adds no format, default, or interaction details (e.g., behavior when both are omitted).

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?

Tautological: description restates name/title.

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 when-to-use or when-not-to-use guidance, no mention of prerequisites, and no pointer to the sibling get_thinking_history or sequentialthinking_tools. The phrase 'one session or all sessions' hints at the parameter choice but does not tell the agent which situation calls for which scope.

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