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 usefully discloses pricing ($0.05 / plan / first run free), but it does not say whether starting a loop mutates state, what side effects occur, whether it is idempotent, what permissions are needed, or what the agent should expect after invocation.

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?

The description is a single front-loaded sentence with no wasted wording, and the pricing detail is useful for cost-aware agents. It could be slightly more structured, but it is appropriately concise.

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 three-parameter tool with no annotations and no output schema, the description is missing too much: parameter semantics, usage context against siblings, mutation/side-effect behavior, and post-invocation expectations. The pricing note is helpful but insufficient to make the definition complete.

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 0% for all three parameters (catalog_id, catalog, selector_class). The description mentions 'current live catalog' but does not explain the distinction between catalog_id and catalog, nor what selector_class controls. It leaves every parameter undocumented.

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 states a specific verb and resource: start a recovery loop run against the current live catalog. It is clear enough to distinguish from status-checking siblings like loop_status, but it does not explicitly contrast with apply_fix or verify_recovery.

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 explicit guidance on when to use this tool versus the sibling tools apply_fix, loop_status, register_catalog, or verify_recovery. The phrase 'recovery loop run' implies a workflow, but no conditions, prerequisites, or exclusions are stated.

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