Alion: company, startup and market intelligence

Get a company profile

Read-onlyIdempotent

Everything Alion knows about one company - for due diligence, account research, a competitor or supplier check: identity (name, local name, domain, website, description, founded year, size band with confidence), headquarters and offices on file (city, country, kind, open jobs per office), industries, public links (LinkedIn, GitHub, X), the ATS board and when it was last verified, live hiring aggregates (open roles, added in 30/90 days, closed in 30 days, velocity, senior/remote/visa/equity counts, top roles, hiring countries, nine weeks of open-role history, average stated and estimated pay, the hiring-signal breakdown), the technology stack seen in its postings, funding rounds with their investors, the funds and accelerators behind it, headcount and revenue on file, public traction signals, growth events of the last 90 days, a dated story of its stages, visa-sponsor register matches, and freshness stamps for every source. Identify the company by id, domain, url or name (a name goes through resolve_company). Paid from the account's credits (a few cents a profile). Docs: https://alion.io/developers/docs

A3.6/5.0

Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive/non-open-world, so the safety profile is covered. The description adds genuinely new behavioral context: the operation is billed against account credits, name lookups route through resolve_company, and results carry per-source freshness/verification stamps. No contradictions with annotations.

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

Conciseness2/5

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

The purpose is front-loaded, but the body is one enormous run-on colon-list enumerating dozens of return fields. Since an output schema already exists, this enumeration is largely redundant and makes the description far larger than needed for tool selection.

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 a rich output schema, the description need not explain return contents; it correctly covers identification options, cost, and use contexts, which is sufficient for correct invocation. It lacks explicit sibling routing, keeping it below the top mark.

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?

Schema description coverage is 100%, so the schema already documents all four identifiers, including 'prefer the domain when you have it.' The description's one semantic addition ('a name goes through resolve_company') largely duplicates the schema's own note that name is 'matched like resolve_company.' Baseline 3 for high coverage is appropriate.

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

Purpose4/5

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

The opening 'Everything Alion knows about one company' plus the explicit use cases (due diligence, account research, competitor/supplier check) state a clear verb and resource. It does not, however, distinguish itself from siblings like search_companies, similar_companies, or get_job, and the remainder reads as a return-field inventory rather than purpose. Clear but not sibling-differentiated.

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?

It names concrete contexts ('for due diligence, account research, a competitor or supplier check') and discloses the credit cost ('a few cents a profile'), which helps an agent decide whether to call it. It stops short of stating when-not-to-use or explicitly routing to a cheaper alternative such as search_companies.

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