il.rewrite.noop_replace

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

No annotations are provided, so the description carries the full burden. It gives no information about side effects (e.g., whether it modifies the database, leaves the IL in a different state, or is reversible), nor does it explain what 'no-op' means in this context. The behavioral disclosure is minimal.

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 short but under-specified rather than efficiently informative. Every sentence should add value; here, a single vague phrase does not earn its place because it omits critical context. A helpful description could add a sentence about scope or typical use.

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 complexity of IL rewriting, six parameters (two required), no output schema, and no annotations, the description is far from complete. It fails to inform the agent about return values, behavior, or required state, leaving large gaps.

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% and the description adds no meaning to the six parameters (e.g., 'index', 'level', 'generate_ssa_form'). The agent has no guidance on what these parameters represent or how to set them, making correct invocation difficult.

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 states 'Perform no-op IL expression replacement,' which provides a verb (replace) and a resource (IL expression), but it is ambiguous whether it replaces an expression with a no-op or replaces no-op expressions. It does not differentiate from related sibling tools like il.rewrite.translate_identity or il.rewrite.capabilities, which also manipulate IL.

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. There is no mention of prerequisites, when not to use it, or context that would help an agent decide to invoke it over other IL rewrite tools.

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