check_kev_statusCheck if a CVE is in the CISA Known Exploited Vulnerabilities (KEV) catalog. Returns KEV details including required remediation actions and due dates.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds behavioral context by specifying the return value includes KEV details, remediation actions, and due dates, which goes beyond the annotations.
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 two sentences: the first states the main purpose, the second lists the key return fields. Every word earns its place, with no redundancy or unnecessary detail.
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 one-parameter read-only tool with no output schema, the description is complete. It explains what the tool does and what it returns, making it sufficient for an agent to select and invoke it correctly.
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?
Schema description coverage is 100%, with the required cve_id parameter described as 'CVE identifier'. The description reinforces the parameter's purpose but adds no additional semantic detail beyond what the schema already provides.
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 clearly states the tool checks if a CVE is in the CISA KEV catalog, using a specific verb and resource. It distinguishes itself from siblings like get_cve_details and search_cve by focusing on KEV-specific status.
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 provides clear context for when to use the tool (whenever KEV status is needed) but does not explicitly mention alternatives or exclusions. The narrow scope makes the usage obvious, so it earns a 4 rather than a 3.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Most tools have clearly distinct purposes, but a few pairs overlap: get_current_step vs get_progress, search_cve vs search_by_product, and describe_capabilities vs get_my_capabilities. The descriptions provide enough detail to differentiate them, but agents could still occasionally misselect.
Names overwhelmingly follow a verb_noun snake_case pattern (get_*, list_*, search_*, start_*, etc.). Minor deviations like 'diff' and 'search' (single-word) and 'batch_search' (compound modifier) are predictable and don't disrupt the overall consistency.
With 30 tools, the server is on the heavier side. The broad scope (legal intelligence, CVE data, full workflow engine) justifies many tools, but some are internal or niche (probe_corpus, recommend_subagents) and could be hidden. It's borderline between well-scoped and excessive.
The legal and CVE domains are well-covered: search, provision lookup, validation, diff, coverage, and detailed CVE enrichment. Workflow management is end-to-end. However, get_regulatory_deadlines is referenced by get_regulatory_intelligence_status but not exposed in the toolset, leaving a notable gap.
