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

Goes well beyond the annotations: the annotations only say destructive/openWorld/idempotent, while the description discloses that passing the original post id cascades to all translations and takes their pages offline, and — critically — that passing a translation's own id deletes nothing yet still reports success. That silent-failure trap is exactly the kind of behavior an agent cannot infer from structured fields.

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 trigger and no filler sentences; every clause carries information. The single dense sentence packing both the original-id and translation-id branches is slightly hard to parse on first read, which keeps it just short of ideal.

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 destructive, single-parameter tool with full annotation coverage, a complete schema and an output schema present, the description covers the remaining risk surface: cascade scope, page-offline side effect, and the misleading-success edge case. Nothing an agent needs before invoking it is missing.

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 explains that 'id' is the original post's originalArticleId, so baseline credit is limited. The description nevertheless adds meaning the schema omits: the consequence of supplying a translation's own id (nothing deleted, misleading success result). That is genuine semantic value, though the format/lookup of the id itself is left to the schema.

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 precise verb+resource+scope: 'permanently delete a blog post in every language,' which distinguishes it from update_article and the read/search siblings. It also explicitly excludes a near-neighbor use case with 'Not for unpublishing.' An agent can route to this tool without opening any schema.

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?

Opens with an explicit trigger ('Use this when someone asks to permanently delete a blog post'), names the outcome scope (all languages), and closes with an explicit exclusion ('Not for unpublishing'). Both when-to-use and when-not-to-use are stated outright.

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