psa_population_report

Look up PSA population report by certification number or spec ID. Get card details (year, brand, subject) and complete grade distribution from Auth to PSA 10.

Instructions

Look up PSA card certification details and full population report. Returns card info (year, brand, subject, grade) and complete grade breakdown from Auth through PSA 10, showing how many cards exist at each grade level.

specIDNoPSA spec ID for direct population lookup
Behavior3/5

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

No annotations provided, so description carries full burden. It describes output structure but does not disclose whether the tool is read-only, requires authentication, or has side effects. Missing behavioral details beyond the return format.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with purpose, then explicit return structure. No unnecessary words; every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite no output schema or annotations, description provides a good overview of returned data (card info fields, grade breakdown range). Lacks mention of optional parameters or error handling, but adequate for a simple lookup tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with clear parameter descriptions. Description adds no additional parameter info, so it meets the baseline for high coverage but does not enhance understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the tool looks up PSA card certification details and population report, listing specific return fields. Purpose is specific and distinct from unrelated siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implies use when PSA population data is needed, but lacks explicit guidance on when to use which parameter or alternatives. No direct siblings to distinguish, so minimal guidance is acceptable.

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