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

No annotations are supplied, so the description carries the full behavioral burden. It does disclose real behavior: undo reverses a previously merged change and that reversal is recorded. However, it never says what merge or dismiss actually do to the firm's configuration, whether merge is irreversible, or what permissions are required, which are significant gaps for a mutation tool.

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, front-loaded with the action set and resource, followed by the one non-obvious semantic ('undo reverses a merged change and records it'). Nothing is padded and every clause carries information.

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 three-parameter mutation tool with no annotations and no output schema, the description covers the action vocabulary and undo semantics but omits error conditions, required permissions, and what a successful decision returns. It is workable but not complete for an agent acting unattended.

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 67%, with 'consolidation_id' and 'index' described in the schema and the 'decision' enum carrying no per-value description. The description partially compensates by mapping its three verbs onto the enum and explaining that 'undo' reverses a merged change, but it adds nothing about what 'index' indexes into or how to obtain the consolidation id beyond the sibling pointer.

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 gives concrete verbs (merge, dismiss, undo) applied to a specific resource: a change to how the firm works, proposed by its agents. That is far more specific than the tool name alone. It stops short of differentiating from the sibling decide_approval, which sounds like a parallel decision surface, so a 4 rather than a 5.

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 parenthetical '(see firm_history and what_needs_me)' usefully points to where proposals are discovered before deciding, which is implied when-to-use guidance. There is no explicit when-not guidance and no statement of how this decision differs from decide_approval, leaving the agent to infer routing between two decision tools.

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