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

Annotations already declare destructiveHint=true and idempotentHint=false, so the description does not need to re-prove that deletion is destructive. It adds real value beyond them: the 30-day soft-delete/restore window and the fact that no financial value or transaction is touched. It stays silent, though, on repeated-delete behavior (consistent with idempotentHint=false) and on any effect on related scenarios or goals that reference the grant.

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?

Front-loaded with the action and followed by short, scannable sentences covering side effects, undo, and id sourcing. The two negative clauses ("exercises or sells nothing" / "does not change the asset's value") overlap somewhat, and the trailing advice disclaimer consumes space without aiding invocation.

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 single-param destructive tool with annotations and no output schema, the description covers the essentials: what it does, what it does not do, how to undo it, and where to get the id. Only error/repeat-invocation behavior is left unspecified.

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?

Only one parameter (id) with 0% schema description coverage, so the description must carry meaning — and it does by directing the agent to beyondpayday_list_equity_grants as the source of the id. It does not describe the accepted UUID format or the failure mode for an unknown id, which keeps this from a 5.

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 ("Deletes one stock grant record") and immediately bounds the action by clarifying it exercises or sells nothing and does not change asset value. That scope statement separates it from sibling deletes (delete_asset, delete_holding) whose records back different objects.

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?

Gives the concrete prerequisite for the id ("Get the id from beyondpayday_list_equity_grants") and names the recovery path ("restored for 30 days with beyondpayday_restore_deleted"). It does not explicitly say when to prefer update_equity_grant over delete, but the "exercises or sells nothing" clause implies the alternative for a real disposal event.

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