FoundRole — AI Job Search & Application Tracker MCP for Claude & ChatGPT

Compare jobs

jobs_compare

Read-only

Compares 2 to 4 jobs side by side using the same FoundRole analysis fields: resume match, missing skills, H-1B and E-Verify signals, ghost-job risk, posted pay, and market salary estimates.

comparison_refs accepts exact FoundRole job IDs returned by jobs_search and exact external comparisonRef URLs returned by jobs_analyze_external. Analyze each outside job first; a bare URL that has not been analyzed cannot be compared because FoundRole does not have its posting facts. Preserve every reference exactly, keep the user's requested order, and do not send duplicates.

Input Schema

A4.4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds genuine behavioral context beyond that: the analysis fields produced, the hard constraint that un-analyzed URLs cannot be compared, and the ordering/dedup invariants the caller must respect. It stops short of describing output format, but that is carried by the output schema.

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

Conciseness4/5

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

Front-loaded with the core action and comparison fields, then a focused second sentence on input constraints. Every sentence earns its place; the field enumeration is slightly long but directly useful for setting caller expectations.

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

Completeness5/5

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 explained, and the description fully covers the one input's format, provenance, and invariants against the annotation-provided safety profile. Nothing an agent needs to invoke it correctly is missing.

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

Parameters4/5

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

Schema coverage is 100% with effectively one parameter, so baseline is 3. The description adds real meaning beyond the schema by specifying the exact provenance (FoundRole job IDs from jobs_search, external comparisonRef URLs from jobs_analyze_external) and the invariants (preserve exact references, keep requested order, no duplicates).

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?

States a specific verb (compares) and resource (jobs) with explicit scope (2 to 4, side by side) and enumerates the exact analysis fields returned (resume match, missing skills, H-1B/E-Verify, ghost-job risk, pay, salary estimates). An agent can distinguish this from jobs_search or jobs_analyze_external, which are named as the sources of its inputs.

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

Usage Guidelines4/5

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

Gives a clear prerequisite workflow: analyze each outside job first via jobs_analyze_external, and notes that a bare un-analyzed URL cannot be compared. Names the sibling tools that produce valid refs. No explicit 'when-not-to-use' exclusion, but the conditional guidance is strong and actionable.

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