mutate_watchlist

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

With no annotations, the description carries full burden. It discloses the confirmation requirement but fails to mention that deletions are destructive, whether the tool has side effects beyond the mutation, or what happens after a create/delete. No detail on permissions or reversibility.

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 concise sentence, front-loaded with the core function. However, it is under-specified rather than efficiently complete, which slightly reduces the score, but there is no wasted text.

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?

This is a multi-action mutation tool with 5 parameters and no annotations. The description omits critical context like parameter combinations, the confirm flag's role, and whether actions are irreversible. An output schema exists but does not compensate for missing operational context. For the complexity, the description is incomplete.

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 schema has 0% description coverage, so the description must explain parameters. It only says 'add/remove a market' without mapping parameters (epic, watchlist_id) to actions. The enum `action` is self-explanatory, but the description does not clarify which parameters are needed for each action, leaving the agent to infer.

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 clearly states the verbs and resources: create/delete a watchlist or add/remove a market. It distinguishes from sibling tools like watchlists (presumably read-only) and create_working_order by focusing solely on watchlist mutation.

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?

No when-to-use or alternative guidance is provided. The only hint is 'Requires confirm=true,' which is a prerequisite rather than context about when to choose this tool over siblings. The description does not mention that watchlists is for viewing or that this tool is for mutations.

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