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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description does add genuinely useful authorization context the annotations do not carry (a live grant or owner/admin/grantor is required), but it stops there and is cut off before any further behavior is disclosed.

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 text ends mid-sentence ("byte for..."), and the opening clause is syntactically broken ("Needs the get right..."). This is under-specification plus truncation rather than tight, front-loaded writing.

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 two-required-parameter read with no output schema, an agent needs to know what `space` and `name` are and roughly what comes back. Neither is covered, and the sentence is incomplete, so the definition is not sufficient to call the tool correctly.

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% for both required parameters, so the description carries the full burden for `space` and `name`. It never explains what either parameter identifies, and the truncated tail may have contained that information but does not deliver it.

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 phrase "one secret's value" identifies the resource and the read action, so an agent can guess this fetches a single secret. But the leading clause ("Needs the get right...") is garbled and the sentence is truncated mid-word, so the verb+resource statement is never made cleanly and no sibling (space_secret_list, space_secret_put, space_secret_grant) is named.

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 states a prerequisite (a live grant, or being owner/admin/the grantor) but never says when to use this rather than space_secret_list or space_secret_grant. There is no explicit when-to-use, no exclusion, and no alternative named.

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