Discover persistent file storage

get_storage

Read-onlyIdempotent

Two buckets accept general-purpose files: public for sharing, private for working data. available indicates whether this deployment is configured. Uses your existing agent identity. Operational limits are per-file/per-request, with no per-agent storage entitlement. Public; no authentication required.

B3/5.0

Behavior3/5

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

Annotations cover readOnly/idempotent/openWorld. The description adds useful operational context: identity usage and the key disclosure that limits are per-file/request with no per-agent storage entitlement. It does not describe what data is returned, but an output schema exists.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Short and mostly front-loaded, but the sentences are somewhat disjointed — bucket description, availability flag, identity, limits, and auth are strung together without clear structure or a leading statement of what the tool returns.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be spelled out. However, with zero params and a discovery-style name, the description should at minimum say what the tool surfaces (e.g., bucket availability/config) to distinguish it from list_storage_files and list_storage_agents.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Zero parameters, so baseline 4 applies. No parameter semantics are needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The title says 'Discover persistent file storage' and the description explains buckets, but the tool name 'get_storage' plus zero parameters makes the actual operation ambiguous. This appears to be a discovery/info tool, but the description never states what is returned or why you'd call it instead of list_storage_files.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No indication of when to use this tool versus list_storage_files or the create/write/delete siblings. A reader cannot tell whether get_storage returns capabilities, usage stats, or a bucket listing.

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