imgui_redo

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool re-applies reversed state and pairs with imgui_undo, but doesn't disclose failure modes (e.g., what happens if there's nothing to redo), whether it's idempotent, or whether state is partially restored. For a zero-parameter state mutation tool, more transparency about its failure behavior would be valuable.

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, zero waste. The description clearly states the operation (redo) and the mechanism (re-applies state reversed by imgui_undo) without padding. Every word serves a purpose.

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?

The tool is simple (zero params, no output schema), so the description covers the core semantics adequately. However, for a state-mutating operation with no annotations and no output schema, it could mention edge behaviors like whether redo fails silently or errors when the undo stack is empty. The pairing with imgui_undo is helpful context but doesn't fully cover the behavioral contract.

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 tool has zero parameters, so parameter semantics are inherently vacuous. With 100% schema coverage and an empty properties object, there's nothing for the description to add about parameters. The baseline of 4 for zero-param tools applies here since there are literally no parameters to document.

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 this tool redoes the last undone operation, pairing it explicitly with imgui_undo. The verb 'redo' plus the resource context (undo history) makes the purpose clear. It doesn't fully clarify what 'redo' means in terms of actions, but it's specific enough to distinguish from the 80+ siblings.

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 mentions the tool re-applies the state reversed by imgui_undo, which implies it should be used after an undo operation. However, it doesn't explicitly state when NOT to use it (e.g., no undo history means nothing to redo), nor does it specify prerequisites or edge cases like what happens when called without a matching undo.

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