add_file_to_changeset

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

With no annotations provided, the description carries full burden for behavioral disclosure but provides minimal information. 'Add a file to a changeset' implies a write/mutation operation, but the description doesn't disclose permission requirements, whether this action is reversible, what happens if the file already exists, rate limits, or what the response looks like. For a mutation tool with zero annotation coverage, this is inadequate.

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 maximally concise with a single clear sentence: 'Add a file to a changeset in ServiceNow.' Every word earns its place - 'Add' (action), 'a file' (object), 'to a changeset' (target), 'in ServiceNow' (context). There's zero waste or redundancy.

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 mutation tool with 3 parameters, 0% schema description coverage, no annotations, and no output schema, the description is severely incomplete. It states what the tool does at a high level but provides no information about parameters, behavioral characteristics, error conditions, or expected outcomes. The agent would struggle to use this tool correctly without additional context.

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%, meaning none of the 3 parameters have descriptions in the schema. The tool description provides no parameter information whatsoever - it doesn't mention changeset_id, file_path, or file_content. The description fails to compensate for the complete lack of schema documentation, leaving all parameters semantically undefined.

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 action ('Add a file') and target resource ('to a changeset in ServiceNow'), providing specific verb+resource pairing. It distinguishes from sibling tools like 'create_changeset' or 'commit_changeset' by focusing on file addition rather than changeset creation or finalization. However, it doesn't explicitly differentiate from potential file-related operations that might exist in other contexts.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing changeset), when not to use it, or what alternatives exist for similar operations. The agent must infer usage from the tool name alone without contextual guidance.

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