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

Beyond the annotations it discloses what annotations cannot: the tool is disabled unless explicitly enabled, requires a separate human-approved grant, consumes an authorized use per call, and returns plaintext only to this client. It also warns against putting the result into documentation or conversation replies, which is exactly the kind of non-obvious, high-stakes behavior a caller needs.

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?

Sentences are dense and mostly earn their place, but the most important fact (what the tool returns) is buried behind multiple prerequisite clauses, and the phrasing "the provider receives the result" is ambiguous.

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 destructive, gated secret-exposure operation with no output schema it covers auth, enablement, consumption, and output handling well, but with 0% schema coverage it leaves binding_id and result_offset (likely paging) entirely undocumented, which is a real gap for a 3-parameter tool.

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 carry parameter meaning, but it only gestures at "project options" and instead references "account" and "workspace" options that do not exist in the schema. binding_id, the second required parameter, and result_offset are never explained, so the guidance is both incomplete and partly misleading.

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 implies a secret-export ("return plaintext secret (or base64 file)") but leads with gating conditions rather than a verb+resource statement, and never names itself relative to the obvious sibling use_secret. An agent can infer the purpose but must read several clauses before it becomes clear.

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?

It gives concrete conditions for use ("Off by default: needs the account, workspace and project options", plus a "separate human-approved secrets.export grant"). However, it offers no guidance on when to pick this over use_secret or how the two differ, so the alternative-selection part of the job is missing.

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