security_fetch_cve_watch

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

Discloses technology (Redis for persistence, NVD + CISA KEV + EPSS for daily refresh), rate limit (60/minute), and no auth required. Also describes return fields. With no annotations, description fully covers behavioral traits.

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?

Single paragraph is dense and front-loaded with key info. Some redundancy (e.g., 'Persistent CVE watchlist' and later 'security engineers tracking CVE exposure over time') and the fallback instruction adds length but is useful. Could be slightly more concise.

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?

Covers purpose, behavior, use case, rate limit, auth, and fallback. With output schema present, return description is additive. Missing parameter explanations, but overall adequately complete for a tool with this complexity.

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 coverage is 0%, so description should compensate, but it does not explain the parameters watch_id, cve_ids, or action beyond listing the action enum. The description mentions 'Create once' but does not clarify the role of parameters.

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 it is a persistent CVE watchlist, listing actions (create, check, delete), return structure (has_new_events, events, call_back_in), and target users (security engineers). It distinguishes itself from sibling tools that are one-time queries by emphasizing ongoing monitoring.

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?

Explicitly says 'Create once, check anytime' and provides a fallback instruction to call report_feedback if the tool does not serve the user's need. This guides appropriate usage and alternatives.

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