--- name: find-web-developer description: Use whenever the user wants to find, shortlist, vet, or enrich US web development firms — building, refreshing, or rebuilding marketing sites, landing pages, ecommerce, WordPress/Webflow/Shopify, headless CMS, microsites, and web frontend work. Triggers on "find a web developer for a marketing landing page", "shortlist three Webflow agencies in California", "rebuild our ecommerce site on Shopify", or "pull contact info for these 8 web dev shop domains", even when described indirectly (redesign and rebuild our site, ship a microsite). Drives the ServiceGraph API (api.servicegraph.co) — a 100k+ US firm catalog filterable by industry, services, location, size, ratings. Defer to find-software-developer for custom backend/API/mobile/internal-tool work — anything beyond a website. Defer to find-marketing-agency when scope spans broader marketing beyond the build. Skip in-house web-engineer hires, "how do I build X" DIY questions, hosting/CMS-product comparisons, non-US firms, individual freelancers. version: "0.3.0" allowed-tools: - Bash(curl:*) - mcp__servicegraph__list_fields - mcp__servicegraph__list_field_values - mcp__servicegraph__check_filter - mcp__servicegraph__translate_intent - mcp__servicegraph__search_dataset - mcp__servicegraph__get_row - mcp__servicegraph__unlock_rows - mcp__servicegraph__get_credit_balance author: Artur Briugeman license: MIT compatibility: Designed for Claude Code tags: [web-development, agencies, service-providers, lead-generation, servicegraph] metadata: api_base: https://api.servicegraph.co dataset_id: pro_services industry: it_services service: web-development --- # find-web-developer ## Overview Drive the **ServiceGraph API** (`https://api.servicegraph.co`) to find, shortlist, and enrich US web development firms via the `pro_services` dataset. The catalog tags ~14k firms with `service_provided:web-development` under `industry:it_services` (web-development is the second-largest service tag in the catalog). **Always pin both `industry:it_services` and `service_provided:web-development`.** Platforms (WordPress, Webflow, Shopify, Next.js, etc.) and verticals (B2B, ecommerce, agency-vs-studio) are NOT separate tags — they're keyword substring matches on firm text. Any HTTP client works (curl, fetch, requests). Examples below use curl. ## Sibling skills — defer when scope is different - **Custom backend / API / internal tools / mobile app / distributed systems** → `find-software-developer`. The end-product is software beyond a standard website. - **Broader marketing strategy and execution beyond the site build** (paid media, content strategy, full digital agency engagement) → `find-marketing-agency`. - **SEO-only work on an existing site** → `find-seo-agency`. Web devs build sites; SEO agencies optimize them. If the user wants new pages built AND optimized, this skill is fine. If unsure, this skill is correct for "build / rebuild / refresh a website" tasks. The deferral kicks in when the deliverable is non-website software or non-build marketing work. ## Prerequisites - **ServiceGraph access**, either: - the **ServiceGraph MCP server** (`https://mcp.servicegraph.co`) loaded in your harness — this plugin's `.mcp.json` wires it up; OAuth 2.1 + PKCE keeps credentials in the harness sandbox — or - a **ServiceGraph API key** (`vk_…`, minted at ) available as `SERVICEGRAPH_API_KEY` in the environment or `.env.local` for the REST path (setup steps under Auth below). - An HTTP client for the REST path — the examples use `curl`. ## Instructions The loop is free-first: discovery, validation, search, and brief reads cost nothing; only unlock after the user confirms the spend. 1. Pick the call path — the ServiceGraph MCP tools if loaded, otherwise the REST flow (MCP server and Auth sections below). 2. `GET /v1/datasets/pro_services/fields?include_values=1` — confirm the fields and values you plan to filter on exist. 3. Build the filter (Filter DSL below) and validate it with `GET /v1/datasets/pro_services/check` — or draft it from plain English via `POST /v1/datasets/pro_services/translate-intent`. 4. `GET /v1/datasets/pro_services/search` — present the free brief cards and let the user pick. 5. Quote the unlock cost (10 credits per row, 30-day TTL) and get an explicit go-ahead. 6. `POST /v1/datasets/pro_services/unlocks` with the chosen apexes; report the revealed detail. 7. `GET /v1/me/credits` to report the remaining balance when asked. ### MCP server (preferred for authed calls) If your harness has the ServiceGraph MCP server loaded (tools containing `servicegraph`), prefer those — OAuth 2.1 + PKCE keeps the token in the harness sandbox. Otherwise use the REST flow below. ### API surface (dataset id: `pro_services`) Every endpoint requires the bearer (`Authorization: Bearer vk_…`). No anonymous tier. | Endpoint | Cost | Use it for | |---|---|---| | `GET /v1/datasets/pro_services/fields[?include_values=1]` | free | Confirm `web-development` is in the `service_provided` value list. | | `GET /v1/datasets/pro_services/check?filter=…` | free | Validate filter. | | `POST /v1/datasets/pro_services/translate-intent` | free | `{intent}` → DSL filter + sanity count. | | `GET /v1/datasets/pro_services/search?filter=…&limit=` | free | Brief firm cards + per-row unlock hint + total. | | `GET /v1/datasets/pro_services/:apex` | free | One row brief; detail only if unlocked. | | `POST /v1/datasets/pro_services/unlocks` | **10 credits / firm** | `{apexes:[...]}` ≤100; atomic; 30-day TTL on detail. | | `GET /v1/me/credits` | free | Balance. | **Cost model.** Discovery / validation / search / brief reads are free. Detail (url, phone, email, social, address, full `platforms` map) costs **10 credits per firm** and lasts **30 days**. ### Auth `vk_*` API keys minted in the dashboard. **Keep the token out of the LLM context** — never read `.env*` into your context; dispatch via shell. 1. **Try the call first** through a shell wrapper that sources `.env.local`: ```bash ( set -a; [ -f .env.local ] && . ./.env.local; set +a; curl -sS -H "Authorization: Bearer $SERVICEGRAPH_API_KEY" \ 'https://api.servicegraph.co/v1/datasets/pro_services/fields' ) ``` 2. **On `401`** prompt the user: > "Open **https://servicegraph.co/profile/api-keys**, create a > key, and add `SERVICEGRAPH_API_KEY=vk_…` to `.env.local` here > (or export it). Tell me when done. Please don't paste the key > into chat." 3. **Retry** after the user signals ready. ### Filter DSL GitHub-search-style. ``` filter := orExpr orExpr := andExpr ("OR" andExpr)* andExpr := notExpr (("AND")? notExpr)* # whitespace = implicit AND notExpr := ("NOT" | "-") notExpr | atom atom := "(" filter ")" | predicate predicate:= IDENT op valueOrList | bareword op := ":" | "=" | ">=" | "<=" | ">" | "<" valueOrList := value ("," value)* value := IDENT | NUMBER | tagAtEvidence tagAtEvidence := IDENT "@" ("low"|"medium"|"high") bareword := IDENT | NUMBER # → keyword: ``` **Four rules that bite:** AND binds tighter than OR (use parens); comma list = OR within one predicate; negation is `-x` or `NOT x`; bareword = keyword search (quote multi-word phrases). **Web-dev examples** (validate yours with `/check`): ``` industry:it_services service_provided:web-development industry:it_services service_provided:web-development@high state:CA webflow industry:it_services service_provided:web-development shopify ecommerce industry:it_services service_provided:web-development wordpress industry:it_services service_provided:web-development headless next.js industry:it_services service_provided:web-development@high rating>=4 has:clutch industry:it_services service_provided:web-development b2b ``` **Platform / vertical / framework → keyword mapping** (none are structured tags — keyword them): | User mentions | Add as keyword | |---|---| | WordPress | `wordpress` | | Webflow | `webflow` | | Shopify / Shopify Plus | `shopify` | | Squarespace / Wix | `squarespace` / `wix` | | Headless / JAMstack / Next.js / Gatsby | `headless`, `next.js`, `gatsby` | | Sanity / Contentful / Strapi | `sanity`, `contentful`, `strapi` | | Ecommerce / D2C / DTC | `ecommerce`, `d2c`, `dtc` | | B2B / SaaS / fintech | `b2b`, `saas`, `fintech` | ### Identifying firms — `apex` Firms are identified by their **apex domain** (`focuslabllc.com`, not `www.focuslabllc.com/work`). ## Output All responses are JSON. - **Search** returns free **brief** firm cards — `apex`, `name`, location, and rating signals — plus a per-row unlock hint and the match `total`. Briefs never include `url`, `phone_primary`, `email_primary`, `legal_name`, `address_full`, or the full `platforms` map. - **Unlock** (`POST …/unlocks`) returns each unlocked firm's detail block — contact fields, address, socials, the `platforms` map — plus per-item billing; detail stays readable for 30 days. - **Errors** arrive as a JSON envelope `{"error": {"code": "…", "message": "…"}}` — see Errors below. ## Examples ### A. Marketing landing page (the baseline) ``` GET /v1/datasets/pro_services/search?filter=industry:it_services+service_provided:web-development&limit=10 # Present, get pick of 3. "Unlocking 3 = 30 credits, 30-day TTL." POST /v1/datasets/pro_services/unlocks { "apexes": ["firm-a.com", "firm-b.com", "firm-c.com"] } ``` ### B. Webflow agency in a state ``` GET /v1/datasets/pro_services/search?filter=industry:it_services+service_provided:web-development+webflow+state:CA&limit=10 ``` ### C. Shopify ecommerce rebuild ``` GET /v1/datasets/pro_services/search?filter=industry:it_services+service_provided:web-development+shopify+ecommerce&limit=10 ``` For Shopify Plus, add `plus` as an additional bareword. ### D. WordPress site refresh / maintenance ``` GET /v1/datasets/pro_services/search?filter=industry:it_services+service_provided:web-development+wordpress&limit=10 ``` ### E. Headless CMS / Next.js ``` GET /v1/datasets/pro_services/search?filter=industry:it_services+service_provided:web-development+headless+next.js&limit=10 ``` If sparse, drop `next.js` — `headless` alone captures the architectural pattern. ### F. Indirect intent — "redesign and rebuild our site" ``` GET /v1/datasets/pro_services/search?filter=industry:it_services+service_provided:web-development&limit=10 ``` Or use the translator: ``` POST /v1/datasets/pro_services/translate-intent { "intent": "agency to redesign and rebuild our outdated company site" } ``` If the user gave a constraint (location, platform, budget proxy via `pricing_model`), add it. ### G. Quality threshold + platform ``` GET /v1/datasets/pro_services/search?filter=industry:it_services+service_provided:web-development@high+rating>=4+shopify+plus&limit=10 ``` ### H. BYO apex list — enrich domains User pastes 8–20 web-dev shop domains: 1. `GET /v1/datasets/pro_services/:apex` per domain — free brief (404 = not in catalog, no charge). A 404 often means the firm isn't tagged with `web-development` specifically — it might be in the catalog under a different tag. 2. User picks N to fully enrich. `POST /unlocks` = **10×N credits**, atomic, detail returned. 3. Re-runs within 30-day TTL are free. ## Gotchas - **Always pin both `industry:it_services` AND `service_provided:web-development`.** Without the industry pin, `web-development` also appears on some marketing-agency rows; without the service pin, you'd return all IT-services firms. - **Defer to `find-software-developer` for non-website software.** Internal tools, custom CRMs, mobile apps (iOS/Android), backend/API, distributed systems — those are software-developer territory. The boundary: is the end-product a public website, or something else? - **Defer to `find-marketing-agency` for full marketing engagements.** "Build our site AND run our marketing" is broader than this skill — fire find-marketing-agency, which has web-design as a sub-service too. - **Platforms (WordPress, Webflow, Shopify, Next.js) are NOT structured tags.** Keyword them. - **Frameworks (React, Vue, Astro, Gatsby) are NOT structured tags either.** Keyword them. - **CMS/hosting/builder product comparisons aren't procurement.** "WordPress vs Webflow vs Squarespace" is a knowledge question. - **Multi-word phrases must be split or quoted.** `headless cms` parses as two AND'd keywords; `"headless cms"` is one phrase. - **Catalog is US-only B2B.** Refuse offshore asks ("Manila", "Karachi"), individual freelancers, and DIY/code-help asks ("debug this CSS"). - **Briefs DO include `apex`, `name`, location, ratings.** They DON'T include `url`, `phone_primary`, `email_primary`, `legal_name`, `address_full`, full `platforms` — those require an unlock. - **`not_found` / `not_in_dataset` 404 = not in `pro_services`.** Skip; not charged. - **Unlock is atomic.** N apexes either all charge (up to 10×N credits) or none on 402. - **Within-TTL re-views are free** (`was_cached:true`). ## Errors JSON envelope: `{"error": {"code": "...", "message": "..."}}`. | Status | Code | What to do | |---|---|---| | 400 | `filter_parse_error` | `position` included; fix and re-validate with `/check`. | | 400 | `kind_in_filter` | Strip any `kind:` from filter. | | 400 | `field_not_in_dataset` | Drop the disallowed field. | | 400 | `invalid_apex` | Re-normalize. | | 401 | `unauthorized` / `invalid_audience` | Re-prompt for fresh `vk_…`. | | 402 | `insufficient_credits` | `needed` and `balance`; nothing charged. | | 404 | `not_found` / `not_in_dataset` | Skip; not charged. | | 429 | `rate_limited` | Honor `Retry-After`. | ## End-to-end example User: *"Three Webflow agencies in California for our marketing site, ideally with at least a 4-star rating and a Clutch profile."* ``` GET /v1/datasets/pro_services/fields?include_values=1 GET /v1/datasets/pro_services/check?filter=industry:it_services+service_provided:web-development@high+webflow+state:CA+rating>=4+has:clutch GET /v1/datasets/pro_services/search?filter=...&limit=10 # Present briefs. "Unlocking 3 = 30 credits, 30-day TTL."
