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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses nothing beyond the implied read: no permissions or auth requirements, no statement of whether freshness/drift records are persisted or merely computed, no rate or scope limits. "Return ... evidence" hints at a read operation but that is inference, not disclosure.

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 with no filler, which is structurally fine. But given seven optional parameters and no output guidance, the brevity reads as under-specification rather than economy.

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?

An output schema exists, so return values need not be described. Still, with seven undocumented parameters, zero annotations, and no usage routing, the definition leaves an agent without enough information to invoke the tool correctly or predict its behavior.

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 0% across seven parameters (decision, source_id, freshness_class, publisher_family, watched_source_id, source_class_family, primary_watchlist_id), and the description explains none of them. The phrase "source-freshness" weakly gestures at freshness_class/source_id but gives no meaning, format, or filtering semantics for the remaining 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 names a verb ("Return") and a resource ("source-freshness and standards-drift evidence") scoped to SecurityRecipes, so the general purpose is discernible. However, it never distinguishes this watch from near-identical siblings such as recipes_agentic_standards_crosswalk, recipes_agentic_threat_radar, or recipes_mcp_tool_surface_drift_pack, and "evidence" is left undefined.

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 statement of when to use this tool, when not to, or which sibling it replaces. An agent has no basis for choosing it over the many other agentic evidence/assessment tools in the same family.

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