PAM overview

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 does disclose the shape of the result (aggregate counts and date-window maintenance forecasts), which is genuine behavioral value for a tool with no output schema, and its aggregate phrasing correctly implies a read-only operation. It says nothing about cost, caching, freshness, or whether the export date is the data cutoff versus a snapshot time.

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?

A single front-loaded sentence that leads with the tool's nature and then enumerates the payload with no filler. The trailing list is dense but each element is informative rather than redundant.

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 one-parameter read-only tool with no annotations or output schema, the description adequately covers what the call returns. However, it leaves the routing decision against pam_expiring unresolved and omits any indication of scope, so an agent can invoke it but cannot confidently choose it over the overlapping sibling.

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?

With a single optional parameter and 100% schema description coverage, the schema already fully documents 'category'. The description echoes it ('counts by support status and category') but adds no syntax, defaults, or semantics beyond what the schema states, so the baseline of 3 applies.

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?

States a specific verb-and-resource pair ('Overview of the SAP Product Availability Matrix data') and then enumerates exactly what the overview contains (export date, version counts, support-status and category breakdowns, EOM timelines). The 'overview' framing implicitly separates it from the lookup-oriented siblings (pam_get_product, pam_search_products), though no sibling is named explicitly to make the distinction airtight.

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?

There is no when-to-use guidance, no prerequisites, and no named alternatives. This gap is substantive rather than cosmetic: the description promises 'how many reach end of mainstream maintenance in 3/6/12/24 months', which overlaps directly with the sibling pam_expiring, and nothing here tells an agent which of the two to pick.

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