sassy_state_get

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

With no annotations, the description carries the burden of disclosing behavior. It states that the tool 'Returns JSON-encoded value,' which is useful, and implies a read-only operation via 'retrieve.' However, it does not explain what happens if the key is missing, or how state is namespaced, leaving gaps.

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 words. It is appropriately sized for a simple getter tool, though it omits useful details.

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 that the tool has two required parameters, no annotations, and no parameter descriptions, the description is too sparse. It does not explain how to specify tool_name or key, nor what 'persistent state' means in context. The output schema exists but is not shown, so the agent may still be uncertain about return values.

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 coverage is 0%, so the description must clarify the two parameters. It only hints that tool_name refers to a tool, but does not define the key parameter or explain the relationship between tool_name and key. The description adds minimal value beyond the raw schema.

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 'Retrieve' and identifies the resource as 'persistent state for a tool,' making its function clear. While it doesn't explicitly distinguish from sassy_state_set/clear, the verb 'retrieve' clearly positions it as the getter in the state trio.

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 guidance is provided on when to use this tool versus sassy_state_set or sassy_state_clear, nor any context about retrieving state that was previously stored. The description offers no usage scenarios or exclusions.

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