Stop Memory Snapshots

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

The annotations only declare readOnlyHint, destructiveHint, and idempotentHint as false, so they provide little safety context. The description adds meaningful behavioral detail: existing snapshot files are retained, the final authorization check is performed by Montycat, and the action applies to exactly one existing in-memory keyspace. This clarifies non-destructiveness and preconditions beyond what annotations alone convey.

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?

The description is compact and well ordered. The first sentence states the core purpose, the second paragraph provides two important side-effect/context facts, and the Args section clearly ties the parameter to its role. No sentence is wasted.

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 tool with one simple parameter and no output schema, the description covers the main action, the key side-effect, and an important precondition. It does not mention error cases or explicitly reference how to resume snapshots, but the core operation is adequately specified for correct invocation.

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%, and the schema only names the required parameter as 'Keyspace'. The description compensates by explaining that keyspace must be an explicit, existing in-memory keyspace whose snapshot schedule stops. This adds real semantic meaning and reduces ambiguity about what value to provide.

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 opens with a specific verb and resource: 'Stop scheduled snapshots' for an explicit in-memory keyspace. It clearly distinguishes the operation from siblings like montycat_start_snapshots and montycat_clean_snapshots by focusing on stopping a schedule rather than creating, cleaning, or managing snapshot content.

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?

The description gives no explicit guidance about when to use this tool versus its siblings. It does not mention montycat_start_snapshots as the counterpart for resuming snapshots, nor does it state any conditions or exclusions. The only implicit signal is the word 'existing', which weakly implies a prerequisite.

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