Grounded permit Q&A

answer_permit_question

Read-onlyIdempotent

Grounded permit Q&A for a specific Seattle-area address. Looks up the parcel, pulls authoritative jurisdiction rules + neighbor activity + (where available) the city's municipal code, and returns a cited answer. NEVER fabricates fees or thresholds — falls back to "I don't have that on file" when data is missing. Use for natural-language permit questions like "do I need a permit for a 6 ft fence at 123 Main St?" or "what permits does an ADU at this address require?"

TDQS

A4.7/5.0

Behavior5/5

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

Beyond the readOnly/openWorld/idempotent annotations, the description discloses the grounding workflow (parcel, rules, neighbor activity, municipal code) and, critically, the failure mode: it never fabricates fees or thresholds and falls back to "I don't have that on file" when data is missing. That is high-value behavioral context an agent cannot infer from annotations alone.

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?

Three tight sentences: purpose and pipeline first, anti-fabrication guarantee second, concrete usage examples last. Every sentence adds information with no repetition.

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?

With annotations covering safety and an output schema covering the return shape, the description only needs to explain scope and behavior — and it does: what it looks up, what it returns (a cited answer), and how it handles missing data. Nothing an agent needs to invoke it correctly is absent.

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%, so the schema already defines both parameters. The description still adds value by clarifying the question types the tool expects and tying them to a specific parcel address, slightly exceeding the baseline for a fully documented two-parameter schema.

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 (answers grounded permit questions) and resource (Seattle-area parcel permit rules), then spells out the pipeline: parcel lookup, jurisdiction rules, neighbor activity, municipal code, cited answer. This clearly distinguishes it from narrower siblings like check_permit_requirements or estimate_permit_fee, which each cover only one step.

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 concrete natural-language usage examples ('do I need a permit for a 6 ft fence at 123 Main St?', 'what permits does an ADU at this address require?') and scopes it to a specific address. It does not explicitly name when to prefer a sibling tool instead, but the examples make the intended use clear.

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