B2B Buyer-Signal MCP

interpret_hiring_signal

Analyze B2B hiring signals (exec hires, team expansions) to get signal strength, optimal outreach timing, pitch angle, pitfalls, and decision window for sales engagement.

Instructions

Interpret a hiring signal (new exec hire, team expansion, role posting). Returns signal strength, outreach timing, pitch angle, common pitfalls, average decision window. Provide signal_type from: head_of_sales, head_of_revenue, head_of_security, vp_marketing, sdr_team_expansion, head_of_data.

Behavior2/5

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It states the tool returns analysis fields but does not reveal whether it is read-only, requires authentication, or has side effects. The behavioral profile is opaque beyond the listed outputs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with the action, and contains no superfluous content. Every word adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simplicity of the tool (one parameter, no output schema), the description adequately covers the input and output. It lacks some behavioral context and usage guidelines, but is otherwise complete for a straightforward interpretation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The only parameter, signal_type, has an enum defined in the schema. The description repeats the enum values but does not explain what each signal type means or how they differ. With 0% schema description coverage, the description adds marginal value—it lists values but lacks semantic explanation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool interprets a hiring signal, lists the return fields (signal strength, outreach timing, etc.), and specifies the input enum values. This distinguishes it from sibling tools like interpret_expansion_signal or interpret_funding_signal.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description tells the agent to provide a signal_type from a list, but does not give explicit guidance on when to use this tool versus alternative interpretation tools (e.g., interpret_leadership_change). Usage context is implied by the signal type names, but no when-not or exclusions are stated.

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