Contractor Toolkit
An AI plugin marketplace for contractors.
Tell Claude about your company once, and it writes your estimates, proposals, bid packages, contracts, RFIs, daily logs, and pay apps — in your brand, in your voice, the way a senior PM would.
Built for general contractors, design-builders, and specialty trades. Free, open source, yours to fork.
What you get
| Plugin | What it does |
|---|
| contractor-initialize | The setup wizard. Answer questions about your company once — name, colors, logo, voice, markets, defaults — and every skill below gets configured automatically. |
| contractor-brand | Keeps every document on-brand: your colors, fonts, logos, and how your company sounds. |
| contractor-docs | The document engine. Clean, premium HTML and DOCX output — the kind of paperwork that wins work. |
| contractor-estimating | The full preconstruction pipeline: ROM → Conceptual Budget → Formal Bid, plus plan takeoff, scope checks, sub bid packages, bid leveling, contracts, and subcontracts. |
| contractor-extras | The everyday paperwork: proposals, timelines, change orders, RFIs and RFI logs, submittals, daily logs, look-aheads, punch lists, incident reports, capabilities statements. |
| contractor-subs | For subcontractors: quote GC bid invitations, change order requests, T&M tickets, progress pay applications. |
Everything is plain Markdown — read it, edit it, make it yours.
Get started in 3 steps
1. Get the code
gh repo fork Sunrise-Systems/contractor-toolkit --clone
cd contractor-toolkit
(Or just clone it. Forking lets you save your company's configured version.)
2. Install in Claude Code
/plugin marketplace add /absolute/path/to/contractor-toolkit
/plugin install contractor-initialize@contractor-toolkit
/plugin install contractor-brand@contractor-toolkit
/plugin install contractor-docs@contractor-toolkit
/plugin install contractor-estimating@contractor-toolkit
/plugin install contractor-extras@contractor-toolkit
Subcontractor? Add /plugin install contractor-subs@contractor-toolkit.
3. Run the wizard
/initialize
Claude interviews you — company name, brand colors, logo files, how you talk, who your clients are, your estimating defaults, what makes you win work. Takes about 10 minutes. Every answer flows into every document the toolkit ever produces.
That's it. Try:
/rom → ballpark budget from a project description
/estimate → full pipeline, idea to formal bid
/proposal → branded client proposal
/daily-log → site report from the super's notes
A typical project, start to finish
/project-intake Qualify the lead
/rom "You're looking at roughly $X–$Y" — before design starts
/plan-takeoff Quantities from the drawings when plans arrive
/conceptual-budget CSI-structured budget + scope gap check
/sub-bid-package Send trades out to bid
/bid-leveling Bids come back — compare apples to apples
/formal-bid The proposal that wins the job
/contract Signable contract from the accepted bid
/subcontract Agreements for your awarded subs
/lookahead Run the job week to week
/rfi-log /change-order /daily-log /submittal The paperwork as it happens
/punch-list Close it out
/capabilities-statement Win the next one
Share it with your team
After /initialize, push your configured fork to a private repo:
gh repo create my-company-skills --private --source=. --remote=origin --push
Teammates clone it, install the marketplace, and get your company's skills with zero setup.
Use it on claude.ai too
Want these skills in the claude.ai web app or Cowork? After running /initialize, build standalone packages:
./scripts/build-dist.sh
Then upload zips from dist/zips/ at Settings → Skills → New skill. Order matters: zips built before /initialize contain unconfigured templates (the build script warns you). See dist/README.md for details and which skills depend on each other.
Make it yours
Every skill is a Markdown file under plugins/<plugin>/skills/<skill>/SKILL.md. Common customizations:
- Swap the cost benchmarks in
contractor-estimating/skills/estimating-workflow/references/cost-reference.md for your historical numbers
- Replace the California license classifications in
sub-trade-mapping.md with your state's
- Add your standard exclusions and clarifications to the master libraries
- Drop your licensed AIA boilerplate into
contractor-brand/skills/brand/resources/ and /contract uses it automatically
Improvements that would help any contractor? PRs welcome.
