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

Beyond the annotations, the description discloses the human-approval gate, the approval_required intermediate state, the two-call retrieval pattern, and that the token is shown only once — all high-value behavioral facts for a write tool. Two blemishes: the 'call again with the same arguments' instruction sits in tension with idempotentHint=false, and the final sentence about payments/confidential data/sign-ins restates authority rules in a way that does not map onto this tool's actual data_class enum (public/internal).

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?

Only three sentences, but the first is ungrammatical and missing its verb, so the reader must reconstruct the auth requirement, and the third sentence is a confusing coda that does not obviously apply to this endpoint. The most important fact — create then re-call to get the one-time token — is buried in the middle rather than front-loaded.

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 7-parameter mutation behind human approval, the description covers the essentials an agent needs: auth scope, the approval wait, the retry-to-retrieve pattern, and the one-time token. An output schema exists, so return shape need not be explained, and the remaining gaps (what happens on denial, how to check status via trooth_delegations) are minor.

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 100%, so the schema already explains every parameter, making 3 the baseline. The description adds no parameter-level detail (no hint at role examples, expiry limits, or why data_class is restricted), and its mention of 'confidential or restricted data' actively conflicts with the public/internal enum, so it does not compensate with useful meaning.

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 middle sentence states the core action and scope: 'Asks for one data-sharing delegation,' which is clearly distinct from trooth_delegations (list) and trooth_delegation_revoke. However, the opening sentence ('With the workspace's agent key with the settings area') is syntactically broken, and the closing sentence about payments, confidential/restricted data, and sign-ins muddies what the tool actually does versus what it merely notes.

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 genuinely useful procedural guidance — expect status approval_required, then call again with the same arguments to obtain the delegation and its token. It also states the auth prerequisite (agent key with settings scope, Bearer tra_...). What is missing is any routing advice relative to siblings: no mention of when to use trooth_delegations to check status or trooth_delegation_revoke to undo one.

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