vault_execute

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

The description discloses that credentials are never exposed and flow through a secure side channel, which is critical. However, it omits other behavioral traits like error handling, idempotency, or required permissions. Since no annotations exist, the description should cover more.

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 extremely concise, using only two sentences to convey the purpose and a key security property. Every word adds value, and it is front-loaded.

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?

With no output schema and 5 parameters, the description fails to explain return values or clarify the usage pattern for handle vs auto_detect. More context is needed for a first-time user.

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?

All parameters have descriptions in the schema (100% coverage), so the description adds minimal semantic value. It hints at the relationship between handle and auto_detect but does not explicitly state they are mutually exclusive.

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 the tool executes an action using a credential, distinguishing it from other vault tools like vault_find or vault_store. However, it does not explicitly differentiate from memory tools or provide a broader context.

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?

No guidance is given on when to use this tool versus alternatives, such as when to prefer auto_detect over handle, or prerequisites like needing a handle from vault_handles.

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