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

With no annotations provided, the description carries the full behavioral burden. It discloses the return shape ('Returns agent score + band alongside the Kin Score') and the ANDed DO satisfy/do NOT satisfy filter semantics. It does not disclose pagination behavior, default results when no filters are applied, or any safety/read-only characteristic — gaps that are more consequential given the absence of 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?

Two sentences with the core purpose front-loaded before the examples, and every clause carries information. The 'INFLUENCE —' branding prefix and the word 'alongside' add mild flourish but no real waste. It is dense yet readable, though marginally longer than strictly necessary.

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?

Given 8 all-optional parameters, no output schema, and no annotations, the description covers the core mechanism and return fields well but omits several things an agent needs: what happens when no filters are supplied (presumably the full ranked catalog), pagination via page/limit, and the meaning of 'band.' The Kin Score reference is treated as known context, which may confuse an agent with no prior exposure.

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 75%, so the baseline is 3, but the description adds genuine meaning beyond the schema: it maps has/missing onto concrete cohort concepts ('OAuth-capable MCP cohort', 'addressable market for a fix') and ties the returned score+band fields to the filter semantics. The context, sort, and min_score parameters are not elaborated in the description, but the schema already describes them adequately.

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-resource pairing — 'Rank providers by agent readiness' — and scopes it to 'the whole catalog,' which differentiates it from a single-provider lookup. The has/missing filter mechanism gives it a distinctive identity among the many find_* siblings. It stops short of 5 because it never names the sibling tools it competes with (e.g., get_agent_readiness, agent_readiness_dimensions), leaving differentiation implicit.

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?

Provides concrete, instructive examples: has='mcp_server,protected_resource_metadata' for the OAuth-capable cohort and missing='agent_card' for the addressable-market view, which effectively teaches when to use each filter mode. However, it gives no guidance on when to choose this tool over get_agent_readiness, readiness_gates, or agent_readiness_dimensions — the agent must infer routing from the name alone.

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