storage

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

No annotations are provided, so the description carries the full burden. It does not disclose whether set/remove/clear mutate persistently, what clear actually wipes (all keys vs. one), whether the key/value are required for which action, or any auth/scope context. The mutation semantics are left entirely implicit.

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?

It is a single terse fragment with no wasted words and the action list is front-loaded. But it is under-specified rather than genuinely concise, with no structure to indicate the per-action parameter requirements.

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 4-parameter, multi-mode tool with no annotations, no output schema, and zero schema description coverage, this definition is far too thin. An agent cannot tell which parameters each action requires or what a get returns.

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?

All four parameters have 0% schema description coverage, so the description must compensate. It only echoes the four action values, leaving key, value, and the local/session type enum unexplained, and giving no hint that action dictates which other params are required.

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?

States the resource (storage) and enumerates the four actions, so the general purpose is inferable. However, it is a generic multiplexer whose siblings get_storage, set_storage and clear_storage each do a subset of this more precisely, and the description does nothing to distinguish itself from them.

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 use this combined operation versus the dedicated get_storage/set_storage/clear_storage siblings, nor any note about required parameters per action. Nothing beyond the bare action list is provided.

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