Capture Metadata Snapshot

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 states the snapshot is 'metadata-only' and 'bounded', hinting at non-destructive behavior, but does not explicitly confirm read-only nature, performance implications, or what happens on limit violations. It adds moderate behavioral context.

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, front-loaded sentence with 14 words, making it very concise. However, it sacrifices parameter information, which could be justified as the schema should handle that, but with 0% coverage, it should compensate. Still, the structure is efficient.

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 10 parameters, no output schema, and no annotations, the description fails to explain what a snapshot is, what the tool returns, or how it integrates with siblings. It covers purpose but not the full operational context needed for correct invocation.

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 0%, and the description provides no explanation of the 10 parameters. It does not mention schema, profile, maxTables, or any other parameter, leaving the agent without guidance on how to use them.

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 verb 'Capture', the resource 'metadata snapshot', and specifies it is 'bounded', 'metadata-only', and for 'offline diff and impact analysis'. This distinguishes it from sibling tools like 'ob_compare_metadata_snapshots' which compare snapshots, and 'ob_analyze_metadata_impact' which is for analysis.

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 implies its usage for offline diff and impact analysis, providing clear context. However, it does not explicitly state when not to use this tool or mention alternatives, though the context is clear.

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