insert_rung

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

The description does not disclose any behavioral traits beyond the basic operation. It fails to mention side effects such as shifting existing rungs, error conditions for invalid indices, or any impact on the program structure. The destructiveHint annotation is not elaborated.

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 appropriately concise as a single sentence, which aids quick understanding. However, it is too terse and omits critical details that would make it more useful, balancing brevity at the expense of completeness.

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?

Given the tool's moderate complexity (multiple parameters, destructive annotation), the description is severely incomplete. It does not cover parameter usage, side effects, or usage context, making it insufficient for an agent to correctly invoke the tool without additional information.

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?

The description does not explain the purpose of the parameters like 'instructions', 'comment', or 'expected_revision'. It only references 'mnemonic rung' and 'index' but does not map them to the actual input schema, leaving most parameters unexplained.

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 (insert) and the target (a mnemonic rung) and specifies the position (zero-based index). It distinguishes from other rung manipulation tools by focusing on insertion.

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 provided on when to use insert_rung over other tools like replace_rung or delete_rung. The description lacks any context about typical use cases, prerequisites, or scenarios where insertion is appropriate.

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