save_state

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

With no annotations, the description carries full responsibility for disclosing side effects. It reveals that the operation persists state but does not state whether it overwrites a previous snapshot, whether it is idempotent, whether prior changes must exist, or what happens on success/failure.

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 a single, front-loaded sentence with no filler or redundancy. Every word earns its place, and the main verb 'save' appears first.

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 0-parameter tool with no output schema, the description gives the core operation but leaves scope ambiguous: 'current state' could mean session, tree, or global storage. It also does not explain return or success behavior, so an agent can call it but cannot fully predict its consequences.

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 has zero parameters and an empty input schema, so there are no parameter meanings for the description to clarify. Per the zero-parameter baseline, the description adequately covers the input contract by not omitting anything relevant.

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 states a clear action ('save') and a clear object ('current state to storage'), so an agent can infer the tool's basic purpose. It does not explicitly differentiate from sibling tools, but no sibling offers an equivalent save/persistence operation, making the purpose reasonably distinct.

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 guidance on when to invoke this tool versus alternatives. The word 'Manually' implies it is used for explicit, user-triggered persistence, but no conditions, prerequisites, or alternative tool references are provided.

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