Remove Spam Blacklist Entry

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

Annotations already declare destructiveHint=true and idempotentHint=true, but the description adds genuinely new context: matching is case-insensitive so stored casing may differ, and the blast radius spans every domain on the account. It does not say whether removal requires prior existence or what happens on a miss, though idempotentHint covers that.

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?

Three short sentences, each carrying distinct information, with the core action front-loaded. No redundant restatement of the title or schema.

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?

Output schema and annotations are rich, so the description does not need to cover safety or return shape. The remaining gap is the role of the required `domain` argument given account-wide tooling, plus any permission requirements, which an agent would want before invoking a destructive operation.

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%, so the baseline is 3; the description does add one piece of meaning beyond the schema, namely that entry matching is case-insensitive. However, it never explains why a required `domain` parameter exists when the list is described as shared across all domains, which leaves the most confusing parameter unexplained.

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 ("Removes an entry from the spam blacklist"), which cleanly separates it from add_spam_blacklist_entry and the whitelist siblings. It does not explicitly name a sibling alternative, but the resource is unambiguous.

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?

Usage is only implied by the operation itself; there is no when-to-use vs. add_spam_blacklist_entry / remove_spam_whitelist_entry guidance and no stated prerequisites. The account-wide scope note reads more as a warning than as routing guidance.

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