ise_ers_list_ancendpoint

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

No annotations are provided (no readOnlyHint, destructiveHint), so the description carries the full behavioral burden. It discloses pagination behavior but says nothing about whether this is a read-only operation, requires authentication, what the response format is, or the max page size limits. For a listing tool, the lack of any note about read-only status or rate implications is a meaningful gap.

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 extremely concise at two short sentences with zero wasted words. It front-loads the core purpose ('List all ANC Endpoints') and flags the pagination behavior. Extremely efficient, though slightly under-specified for the completeness it needs.

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 simple paginated list tool with no output schema and low parameter coverage, the description is sparse. It would benefit from noting that ANC Endpoints are Adaptive Network Control endpoints, the relationship to ise_ers_get_ancendpoint/ise_ers_search_ancendpoint, and default page size behavior. The 'List all' claim combined with pagination suggests enumeration semantics that aren't fully explained.

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?

Only 1 of 3 parameters (deployment) has a schema description, giving 33% coverage. The description itself adds no parameter detail. The deployment parameter has rich semantic meaning in its schema description (name/slug/number formats and fallback behavior), but the page and size parameters are bare integers with defaults, and the description doesn't add meaning beyond pagination context. Schema does most of the work here, but coverage is low so the baseline is a 3.

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 the purpose clearly: 'List all ANC Endpoints' with pagination. However, it doesn't distinguish itself from sibling tools like ise_ers_list_ancpolicy, ise_ers_get_ancendpoint, or ise_ers_search_ancendpoint, making it harder for an agent to know why to choose this specific list operation over related alternatives. The verb+resource is clear but the differentiation gap holds it to a 3.

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?

'Paginated' implies this is the listing operation and that page/size control the result set, which gives some usage context. However, there's no explicit statement of when to use this vs ise_ers_search_ancendpoint (which likely does filtered search) or ise_ers_get_ancendpoint (single item). The 'Paginated' mention hints at full enumeration use but offers no exclusions or alternatives.

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