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

There are no annotations, so the description carries the full behavioral disclosure burden. It does well by explicitly stating what the tool returns: disc breakdown, plastics, wear states, confidence ratings, slot coverage, and deep links. The 'Retrieves' wording implies a read-only operation, which is a sensible behavioral signal even without an explicit readOnlyHint.

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 entire description is one dense but efficient sentence that front-loads the action, gives concrete input examples, and summarizes the return payload. Every clause adds value without repeating the schema or padding the text.

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 read-only retrieval tool with no output schema, the description covers the essential ground: accepted input formats, the nature of the operation, and the key output categories. It does not mention error cases or behavior when both parameters are supplied, but this is a minor gap given the tool's simplicity.

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?

Both parameters are already described in the schema with examples, so the baseline is 3. The description adds a little extra context by mentioning 'slug link' as an accepted input form, which is not explicitly in the schema, but it does not clearly map that format to either parameter or clarify precedence when both parameters are provided.

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 a specific verb ('Retrieves and inspects') and a clear resource ('a player's saved disc golf bag from a BagIQ share link'), and enumerates the returned breakdown. It does not explicitly contrast with sibling tools like analyze_bag or find_gaps, so it lacks active sibling differentiation, but the core purpose is unambiguous.

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 the use case: when you have a BagIQ share link, short share ID, or slug link and need the saved bag contents. However, it does not say when NOT to use this tool or explicitly point to alternatives such as analyze_bag or build_minimal_bag, leaving the selection decision to inference.

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