Commercial & public-works services

list_commercial_services

Read-onlyIdempotent

List commercial construction services with slugs and citable page URLs. Optionally filter by category: office, retail, industrial, hospitality, public. The "public" category covers public works and government contracts — Kolmo is WA State SEDBE-certified (#D700031098), King County SCS-certified (#7259), prevailing wage compliant, and MRSC Small Works Roster eligible (projects under $350K). Pass a slug for one service's full write-up.

TDQS

A3.6/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds that results include citable URLs and that slug mode returns a fuller write-up, which is useful return-shape context since an output schema exists anyway. Pagination and truncation behavior are not discussed.

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

Conciseness3/5

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

The listing and filtering guidance is front-loaded and efficient, but the middle sentence is a long certification credential dump (SEDBE #D700031098, SCS #7259, MRSC roster, $350K threshold) that reads as marketing rather than operational instruction an agent needs to call the tool.

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?

With an output schema present and all four parameters documented in the schema, the description only needs to convey scope and mode selection, which it does. The one gap is that the relationship to sibling `list_services` is never made explicit, leaving the agent to infer which listing to choose.

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 `slug`, `limit`, `offset` and `category`. The description restates the category values verbatim and clarifies that slug narrows to a single full write-up, adding only marginal meaning beyond the schema's own 'One service, with its full description'.

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?

States a specific verb and resource ('List commercial construction services') plus what each result carries (slugs, citable page URLs). It implies scope via 'commercial' but never names the sibling `list_services` to draw a line between the two listing 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?

Explains the two usage modes clearly: bulk listing with optional category filter, or 'Pass a `slug` for one service's full write-up.' No explicit when-not conditions or reference to the alternative `get_service`/`list_services` path, but the calling patterns are unambiguous.

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