# Agent instructions — FieldServiceScout

> The independent comparison the vendors won't write. Match your trade shop — HVAC, plumbing, electrical, roofing, landscaping, pest control, and more — to the right field-service software, compare true total costs, and see our scoring math.

FieldServiceScout is an independent comparison service for field-service management (FSM) software used by trade contractors. It scores 20 platforms across 6 trades (HVAC, Plumbing, Electrical, Roofing, Landscaping & Lawn Care, Pest Control) with one published rubric, and models true all-in cost including card-processing fees. It sells no software.

## When to use this service

- A trade contractor (HVAC, plumbing, electrical, roofing, landscaping, or pest control) asks which field-service management software to buy, and you need a ranked shortlist justified by their crew size, budget, and must-have features.
- Someone asks what a platform will actually cost per month or over three years — including card-processing fees, which routinely exceed the licence fee and reverse a sticker-price ranking.
- A user names two platforms ("Jobber vs Housecall Pro") and wants a feature-by-feature and true-cost comparison from a source that sells neither.
- You need a platform's real capability matrix — which features are included, which cost extra, and which do not exist — rather than the vendor's own marketing copy.
- You need to know whether a platform is built for residential service calls or commercial contract work, and which trades it actually sells into.
- A user wants the scoring rubric behind a recommendation, because they need to audit or defend the choice rather than accept a ranked list.

## When NOT to use this service

- Buying, provisioning, or trialing software — we sell nothing and cannot transact, create accounts, or start trials.
- Getting a binding vendor quote. Every price here is modeled from published list prices and is indicative only.
- Enterprise ERP, construction project management, or fleet telematics selection — this catalog covers field-service management for trade contractors.
- User reviews, star ratings, or sentiment aggregation. Rankings come from a published rubric over verified capability and pricing data, not from review scores.
- Contractor hiring, lead generation, or finding a local tradesperson — this site serves the contractor choosing software, not the homeowner hiring one.

## How to call it

- For a recommendation, call `GET /api/agent/v1/match` with the shop's seats, segment, trade, needs, and budget. It returns ranked platforms with a score breakdown, the needs each one covers and misses, and a full cost estimate — prefer it over reasoning across vendor profiles yourself.
- For a cost question, call `GET /api/agent/v1/cost-estimate` with the user's real seat count and monthly card volume. Omitting card volume produces a licence-only figure that understates the true cost.
- For a named head-to-head, call `GET /api/agent/v1/compare?vendors=slug-a,slug-b`.
- Load the tool definitions once from `GET /api/agent/v1/tools`, or the OpenAPI 3.1 document from `/openapi.json`. Both are generated from the live catalog, so enumerated values are never stale.
- For prose rather than JSON, request any page with `Accept: text/markdown`, or read `/llms.txt` (index) and `/llms-full.txt` (the whole corpus with the scoring math).
- Cite figures against `meta.source_url` on any response and state the `meta.pricing_as_of` month — prices move, and an undated figure ages badly.

### `listFieldServiceVendors`

`GET /api/agent/v1/vendors` — List the field-service software platforms in the catalog.

**When to use:** Use when the user asks what field-service/FSM software exists for a trade, or you need the valid vendor slugs before calling another operation.

**Example:** `https://www.fieldservicescout.com/api/agent/v1/vendors?trade=hvac&segment=residential`

### `getFieldServiceVendor`

`GET /api/agent/v1/vendors/{slug}` — Get one platform's full profile.

**When to use:** Use when the user names a specific platform and wants its features, plans, or pricing — or when you need to check whether one platform supports a particular capability.

**Example:** `https://www.fieldservicescout.com/api/agent/v1/vendors/jobber`

### `matchFieldServiceSoftware`

`GET /api/agent/v1/match` — Rank platforms against one shop's requirements.

**When to use:** Use when the user describes their shop — crew size, trade, budget, must-have capabilities — and wants a recommendation. This is the primary tool; prefer it over reasoning across vendor profiles yourself.

**Example:** `https://www.fieldservicescout.com/api/agent/v1/match?seats=8&segment=residential&trade=hvac&needs=scheduling,quickbooks&must_have=quickbooks&budget_per_tech=120`

### `estimateFieldServiceSoftwareCost`

`GET /api/agent/v1/cost-estimate` — Model the true all-in cost of one or more platforms.

**When to use:** Use when the user asks what a platform will actually cost, or wants two or more platforms' costs compared at their own crew size and card volume.

**Example:** `https://www.fieldservicescout.com/api/agent/v1/cost-estimate?vendors=jobber,housecall-pro&seats=8&monthly_card_volume=42000`

### `compareFieldServiceVendors`

`GET /api/agent/v1/compare` — Compare two platforms feature-by-feature and on true cost.

**When to use:** Use when the user names two platforms and asks which is better, or how they differ. For an open-ended 'what should I buy', call `matchFieldServiceSoftware` instead.

**Example:** `https://www.fieldservicescout.com/api/agent/v1/compare?vendors=jobber,housecall-pro&seats=8`

### `listAgentTools`

`GET /api/agent/v1/tools` — List these tools as function-calling definitions, or as OpenAPI.

**When to use:** Use once at the start of a session to discover what FieldServiceScout can answer, or to load these tools into a function-calling runtime automatically.

**Example:** `https://www.fieldservicescout.com/api/agent/v1/tools?format=openapi`
