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

Annotations establish the mutation/safety profile (destructive=true, idempotent=true), and the description goes well beyond them: it enumerates exactly what is destroyed (owner mark, coupons, owner tools), what survives (the card itself), and what the caller must do afterwards (a fresh proof for a later claim). It also discloses the auth behavior on unauthenticated calls (401 plus OAuth flow), which no annotation conveys.

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?

Three short sentences, front-loaded with the action and its side effects, followed by the consequence and the auth prerequisite. No filler, no repetition of name or title.

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 single-parameter destructive mutation with no output schema, the description covers the action, what is destroyed and preserved, the follow-up implication, and authentication behavior. An agent has everything needed to decide and to call it correctly; return shape is not required since there is no output schema.

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% for the single 'domain' parameter, so the schema already documents format and an example ('acme.ai'). The description adds nothing about the parameter, so the baseline 3 for fully-covered schemas applies.

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 opening sentence gives a specific verb and resource ('Give up the claim on a card'), and the follow-up explicitly separates this from a card deletion by stating the card stays in the Atlas. It is clear what the tool does, though it never names the natural counterpart (atlas_owner_claim) or any other sibling explicitly to anchor the distinction.

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 gives a prerequisite ('Needs a signed-in inite.ai account: a guest call answers 401 and starts the OAuth flow') and a consequence ('A later claim needs a fresh proof'), which is useful context. However it never states when an agent should release a claim versus not, only what the call requires and what follows.

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