Analyze Metadata Impact

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

Without annotations, the description carries the full burden. It only states the tool summarizes impact but does not disclose output format, authentication needs, side effects, or whether it is read-only. The lack of output schema exacerbates the opacity.

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 a single concise sentence, front-loading the main purpose. However, it sacrifices informativeness for brevity. A slightly longer description with structured details would be more helpful.

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 5 parameters, including complex nested objects, and no output schema or annotations, the description is too minimal. It fails to explain what the tool returns, how to format the diff input, or what qualifies as 'impact'. The tool's complexity demands more 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%, so the description must compensate. It only mentions metadataDiff, sqlIndex, and businessGlossary by name but provides no meaning for profile, maxResults, or the structure of the object-type parameters. This leaves the agent with insufficient information to correctly populate inputs.

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 'Summarize metadata diff impact' clearly indicates the verb (summarize) and resource (metadata diff impact). The mention of optional SQL usage index and business glossary evidence adds specificity. However, it does not fully differentiate from siblings like ob_generate_metadata_change_report which also likely summarize changes, but the focus on 'impact' provides some distinction.

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 explicit guidance on when to use this tool versus siblings. The description mentions optional inputs but does not state prerequisites, alternatives, or scenarios. For example, it does not clarify when to prefer this over ob_generate_metadata_change_report or ob_compare_metadata_snapshots.

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