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

No annotations are provided, so the description carries the full behavioral burden. It does add that a signed receipt is returned, but it does not say whether re-probing mutates state, whether it is idempotent, what permissions are required, or what happens if no fix was served — significant gaps for an operation that may trigger a probe.

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 compact sentence with the action front-loaded and no filler. It is efficient, though its terseness contributes to the gaps elsewhere rather than being fully earned brevity.

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 tool with no annotations, no output schema, and an undocumented required parameter, the description is too thin. An agent knows the broad intent but lacks the mutation/safety profile, the precondition failure behavior, and any detail on the identifier it must supply.

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 one required parameter, loop_id, with 0% schema description coverage and no mention of it in the description. The phrase 'a loop run' loosely implies the identifier refers to a loop, but nothing states format, source, or how to obtain the ID.

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 does name a specific verb ('re-probe') and resource ('a loop run whose fix was served') plus a return artifact ('signed recovery receipt'). However, 'loop run' and 'signed recovery receipt' are domain jargon with no elaboration, and it never distinguishes this from the sibling tools loop_status or apply_fix, so an agent must infer how it differs.

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 clause 'whose fix was served' implies the precondition (a fix has already been applied), giving implicit usage guidance. But it never explicitly says when to use this instead of loop_status for checking run state, nor does it name any alternative or exclusion.

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