vault_store_file

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

States 'encrypted vault' and 'upserts', but no annotations provided. Missing details like size limits, encoding, return value, or permissions required for a write 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?

Two sentences, first verb-purpose, second upsert key. No filler, 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?

No output schema, so description should hint at return behavior. It does not mention success/failure indicators. Otherwise covers essential purpose.

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% giving baseline 3. Description adds the upsert key combination (provider, fileName, project), which is not in schema descriptions, enhancing parameter understanding.

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?

Clear verb 'store' with specific resource 'auth file' and example auth.json. Mentions 'Upserts by (provider, fileName, project)' differentiating it from siblings like vault_store (likely more general) and vault_delete_file.

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?

Implied usage: for persisting auth files with upsert semantics. No explicit when-to-use, when-not-to-use, or alternatives among siblings like vault_store.

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