Get Volume Keys

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

The description discloses meaningful behavior beyond annotations: credentials are derived, not stored, stable for the volume, and require no rotation. This complements the readOnlyHint and adds context an agent would not get from the schema or annotations alone.

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 two sentences with no filler, front-loading the most important behavioral fact and ending with a precise parameter reference. Every sentence earns its place.

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?

The description covers credential stability and the source of `volume`, but with no output schema it does not state what the returned keys look like. It also leaves env and region semantics to inference, though the simple read-only nature of the tool reduces the impact of these gaps.

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 description coverage is 0%, so the description must compensate. It only explains `volume` as a name from listVolumes; workspaceSlug, appSlug, env, and region receive no additional meaning despite being undocumented in the 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 title and description together make it clear the tool returns volume credentials, and the description adds that they are derived rather than stored. However, the description never explicitly states the action ('get volume keys') or return value, and it does not differentiate this tool from siblings like getDbCredentials.

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?

The description implies the tool is for retrieving stable volume credentials and instructs that `volume` must come from listVolumes, which is a useful workflow hint. It does not name alternatives or state when not to use the tool, so usage guidance is mostly implicit.

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