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

With no annotations provided, the description carries the full behavioral burden. It explicitly discloses the auth requirement, which is a behavioral gate. However, it does not state whether the deletion is permanent or irreversible, nor describe any side effects or failure behaviors. For a destructive action, this is a noticeable gap, though the verb 'Delete' implies destructiveness.

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 concise and well-structured: a one-line purpose, an auth note, and a clear Args list. Every sentence serves a purpose, and it is front-loaded with the core action. No redundant information.

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?

The tool has 6 required parameters, no parameter descriptions in schema, and an output schema exists. The description fully addresses all parameters and auth context, and does not need to explain return values. It is complete enough for an agent to invoke the tool correctly, though it could optionally clarify behavior when the path does not exist or whether the operation is idempotent, but these are not essential given the other signals.

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 description coverage is 0%, so the description must compensate. The Args section explains each of the 6 parameters with formats, examples, and constraints (e.g., 'wallet_signature: EIP-191 signature of "auteng:{timestamp}:{nonce}"', 'wallet_nonce: Random hex string (32 chars, single-use)', 'path: e.g. "reports/q1.md"'). This adds significant meaning beyond the schema's bare titles.

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 'Delete a document from the agent's workspace.' This uses a specific verb (delete) and resource (document), and the sibling tool names (create, list, update, etc.) make the deletion purpose distinct. No ambiguity.

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?

The description provides clear context that the operation requires EIP-191 wallet signature auth and points to auteng_docs_create for auth details, which gives usage prerequisites. However, it does not explicitly state when to choose this over alternatives or provide exclusions, but the purpose is straightforward enough that the context is adequate.

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