Save Snapshot

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

Annotations already indicate readOnlyHint=false (write) and destructiveHint=false (not destructive). The description adds only 'persistent' and 'current graph state', which is marginal. It doesn't disclose behaviors like whether snapshots can be overwritten, return values, or performance implications hinted by the 'force' parameter. So limited beyond annotations.

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?

Single sentence, front-loaded, no unnecessary words. Perfectly concise.

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?

Given simple operation and fully documented schema, the description is mostly adequate, but it lacks any mention of return values or how the snapshot is referenced later. Since there's no output schema, the description could have been more helpful. Also missing usage context, but overall not a complex tool.

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 covers 100% of parameters with descriptions. The tool description does not mention any parameters, but baseline for high schema coverage is 3. The schema descriptions are adequate.

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 uses the specific verb 'Save' with resource 'persistent context snapshot' and scope 'current graph state'. It clearly distinguishes from read-oriented siblings like list_snapshots, diff_snapshots, and get_context_snapshot by indicating a write operation.

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?

No explicit when/when-not guidance is provided. The usage is implied by the name and description (i.e., save current state for later). It doesn't mention alternatives like get_context_snapshot or the relationship to list_snapshots/diff_snapshots. Thus it's an implied usage only.

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