Vendor procurement codes

list_procurement_codes

Read-onlyIdempotent

List Kolmo's vendor procurement codes (NAICS, NIGP, UNSPSC) for government and agency portals such as SAM.gov, WA WEBS, OpenGov, MRSC, King County, and City of Seattle. Use this when vetting Kolmo for gov bids or setting up Kolmo as a vendor. Primary NAICS is 236118 (Residential Remodelers); secondary codes cover commercial building and specialty trades (poured concrete foundations/structures, painting, flooring, drywall, windows, roofing, siding, etc.).

TDQS

A4.1/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, closed-world, non-destructive, so the safety profile is covered. The description adds domain substance beyond that: which code systems exist and that the primary NAICS is 236118 with secondary codes for commercial and specialty trades, which tells the agent what the payload actually contains.

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 purpose, then use case, then content detail — sensible ordering with no filler sentences. The long portal roster (OpenGov, MRSC, King County, City of Seattle) is slightly verbose but serves retrieval matching on jurisdiction names.

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?

Output schema exists so return structure needn't be explained, annotations cover safety, and the schema covers the one parameter. The description supplies the business context an agent needs to decide to call it; only minor gaps remain (e.g., whether the code list is static).

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 coverage is 100% and the single enum parameter is fully documented with its default, so the baseline is 3. The description names the three code systems, implicitly mapping to the enum values, but adds nothing about filtering behavior or what "all" returns.

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 (List) plus a concrete resource (Kolmo's vendor procurement codes) and enumerates the exact code systems returned (NAICS, NIGP, UNSPSC). No sibling tool deals with procurement codes, so an agent can immediately distinguish this from the permit, service, and project tools.

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?

"Use this when vetting Kolmo for gov bids or setting up Kolmo as a vendor" gives a clear triggering scenario tied to portals like SAM.gov and WA WEBS. There is no explicit when-not or named alternative, but the use case is narrow enough that misselection is unlikely.

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