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

With no annotations, the description carries the full burden and does so well: it discloses destruction scope (cascade-deletes events and event-link rows), a non-obvious side effect (linked bank transactions remain intact and are restored to their original state), and reversibility (soft-delete vs hard-delete via force). These are exactly the traits an agent needs before invoking a destructive operation.

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-loads the core action in the first sentence, then layers cascade scope, side effects, and confirmation guidance in a logical order. Slightly redundant with the schema on the force behavior, but every sentence is otherwise informative.

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?

No output schema or annotations exist, so the description must stand alone, and it covers destruction scope, side effects, and reversibility adequately for correct invocation. Permission/auth requirements and error conditions are unaddressed, which is the only meaningful remaining gap.

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 coverage is 100% and the schema already documents both parameters, including the force default and dealId provenance ('from list_venture_deals'). The description restates the force semantics rather than adding meaning beyond them, so the baseline 3 applies.

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 ('Delete a venture deal') and immediately scopes it with cascade behavior. An agent can distinguish it from sibling deletes like delete_venture_event or delete_venture_platform because the target resource is named precisely and the cascade relationship to those siblings is spelled out.

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?

Provides clear context including a precondition ('Confirm with the user before calling') and explains the force parameter's selection semantics. It does not name alternatives or when-not-to-use conditions, but there is no obvious competing sibling that needs routing.

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