hl_transfer_status

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

With no annotations, the description carries the full burden and does disclose meaningful behavior: the three possible outcomes (landed, pending with retry eligibility, blocked requiring an owner to clear a double-land), which is a real business rule not derivable from any structured field. It stops short of stating read-only nature explicitly or any auth/rate-limit constraints.

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 sentence, front-loaded with the verb and resource, then the outcome enumeration in a compact parenthetical. Every clause earns its place; nothing is padded.

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?

With zero parameters and no output schema, the description usefully compensates by describing the returned states themselves. It is nearly complete for a status tool, missing only explicit read-only framing and any mention of what is needed to identify the transfer.

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?

The tool takes zero parameters, so per the rubric the baseline is 4. The description correctly implies the account scope is implicit rather than passed as an argument, and adds no misleading parameter expectations.

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?

States a specific verb and resource: it reconciles/reports the status of the account's in-flight transfer against the exchange ledger, and enumerates the three result states. It is clearly distinguishable from siblings like hl_transfer (initiates) and hl_account_status (broader account state), though it does not name any sibling explicitly.

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?

Usage is implied: 'in-flight transfer' and 'reconcile' signal this is a post-transfer verification call, most naturally after hl_transfer. However, there is no explicit when-to-use/when-not statement, no mention of the alternative (hl_account_status) and no statement of prerequisites or ordering.

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