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

With no annotations, the description carries the full burden, and it does disclose a useful behavioral trait: instructions are returned conditionally, only while a claim is pending. It says nothing about permissions, session requirements, or whether the result is scoped or exhaustive beyond 'this account.'

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?

A single tight sentence with the resource front-loaded and no filler. The parenthetical 'while pending' clause is slightly tangled but earns its place by signaling conditional content.

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?

No output schema exists, so the description must cover return values, and it does name what comes back (claims, statuses, pending instructions). For a one-parameter read tool this is nearly sufficient, though it omits collection shape and any result limits.

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?

There is a single parameter and schema description coverage is 100% — the session token is fully documented as coming from agent_session_verify. The description adds no parameter detail, so the baseline of 3 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 description names the resource (every claim of this account) and the payload (status and, while pending, instructions), so an agent can tell it retrieves claim state. It does not explicitly distinguish itself from siblings such as claim_start, claim_verify, claim_public, or listing_status, leaving differentiation to inference.

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?

There is no when-to-use statement, no prerequisites, and no named alternative. The agent must infer that this is the read-side companion to the claim_* mutation tools; nothing in the text guides that choice.

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