List Project Vulnerabilities

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

Annotations already cover safety (readOnly, idempotent, non-destructive, openWorld), and the description adds genuinely non-structured context: the cursor-based pagination contract pointing at page_info.end_cursor, plus the terse 'Ultimate' tier marker implying a licensing prerequisite. It stops short of covering rate limits, empty-result behavior, or error semantics, so not a 5.

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?

Front-loaded with the core verb and returned fields, then filters, then pagination – a logical order with no filler. The trailing fragment 'Ultimate.' is efficient but reads as an afterthought and could be fused into a clearer clause.

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 6-parameter tool with no output schema, the description usefully describes the returned record shape and paging loop. However, it omits project_id format expectations, the maximum page size, and any notion of result limits or ordering, which an agent would need to call reliably without schema descriptions.

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 0% schema description coverage across 6 parameters, the description carries the burden and mostly succeeds: it names state, severity, report_type, first, and after (via the cursor mechanism), and the phrase 'a project's vulnerabilities' implies project_id. It does not enumerate allowed enum values, the first<=100 cap, or that no parameters are required, leaving some inference to the schema.

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 ('List a project's vulnerabilities') and enumerates exactly what comes back (severity, state, scanner, CVE/CWE identifiers, location), so an agent can tell this apart from the other gitlab_list_project_* tools at a glance. No sibling overlaps in subject matter, so no disambiguation is required.

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?

Gives concrete operational guidance: filter by state, severity, and report_type, and page using 'first' plus the returned page_info.end_cursor as 'after'. It lacks explicit exclusions or when-not-to-use conditions, but for a read-only listing tool the usage context is clear and actionable.

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