Claude skill packs

Claude skills for one job, packed and ready to run.

Each pack is a set of named, install-ready Claude skills for one job: cold outreach, inbox zero, or idea validation, with the compliance gates and output formats already wired in. Drop it into Claude and your agent runs the whole pipeline.

Built by Merrowby, a studio that builds agent-operated businesses. These outreach, inbox and idea-kill workflows are the ops tooling we run on, not a demo reel.

Two full skills are open in the storefront, read them before you decide. Your email only locks the $49 founding price and pings you the day packs open, no card, no sales call. The price rises at public launch; the early list keeps yours at $49.

    cold-outreach-list-building

    Build a clean, targeted, compliance-ready list of US small-business owners from public sources, ready for a first-touch email sequence.

    Cold outreach: list building

    Turn a vague "SMB owners in {city} / {industry}" into a deduplicated, verified, compliance-scrubbed list you can actually send to.

    When to use this

    Use at the very top of a US B2B outreach pipeline, before writing a single email. Do not skip the compliance gate at the end: it is what keeps the list sendable instead of a liability.

    Inputs

    • ICP: industry (NAICS code or plain words), location (state, metro or ZIP), size band.
    • Volume target: how many verified records you need (e.g. 500).
    • Channel: email, phone, or both. Phone adds TCPA and Do-Not-Call duties.

    Step 1. Pull from public, terms-compliant sources

    Prefer primary public sources over scraped lists:

    • State Secretary of State registries (entity name, agent, status).
    • Google Business Profiles for category, address, website, phone.
    • State professional licensing boards for regulated trades.
    • Company websites for a named owner or a role you can address.

    Record the source URL for every field, so every claim is traceable.

    Step 2. Normalize and dedupe

    • One row per business; collapse duplicate locations under a parent.
    • Normalize phone to E.164, addresses to USPS format, domains to the root.
    • Drop dissolved entities and PO-box-only records.

    Step 3. Find the owner and verify the email

    • Resolve to a named owner or decision-maker, not info@.
    • Verify each email: syntax, MX, SMTP, catch-all detection. Discard the risky.
    • Keep bounce risk under about 2%. A dirty list burns your sending domain.

    Step 4. Compliance gate (a hard stop, not advice)

    A record that fails any check is removed, not flagged:

    • CAN-SPAM: every commercial email needs a valid physical postal address, a working one-click opt-out, and honest From and Subject lines. FTC penalties run to $53,088 per email (inflation-adjusted, effective Jan 17, 2025).
    • TCPA (only if you call or text): marketing calls and texts need prior express written consent; violations are $500 to $1,500 per message. Cold lists rarely carry consent, so default to email first.
    • Do Not Call: scrub any phone list against the FTC National Do Not Call Registry before you dial.

    Output schema

    Return CSV or JSON with: business_name, owner_name, email, email_status, phone, website, address, source_url, icp_match, compliance_ok.

    Quality bar

    • Every row has a source_url and compliance_ok = true.
    • Zero role-based catch-alls in the final send list.
    • Every field is traceable to a public source you could show a regulator.
  • Skip-trace stackEnrich each record to a verified owner name, direct email and mobile through a provider waterfall. Stops at the first confident hit and caps spend per record, so a big list never runs away on cost.Locked
  • Email verification waterfallValidate every address through syntax, MX, SMTP handshake and catch-all detection, then drop the risky ones before send. Keeps bounce rate under 2% so your sending domain stays trusted.Locked
  • Compliance gateEnforce CAN-SPAM, TCPA and Do-Not-Call rules on every record as a hard gate. A row that fails any check is dropped, not flagged, so nothing unsendable ever reaches the outbox.Locked
  • Four-touch sequence writerDraft a value-first, four-touch sequence in your voice with one clear ask per message and a working opt-out. Spaces the follow-ups so you stay persistent without tipping into nagging.Locked
  • Reply triage routerSort every inbound reply into interested, later, unsubscribe or referral, and route each to the right next action. Honors opt-outs on the spot, so nothing warm goes cold and nothing scrubbed gets re-contacted.Locked
  • Sending-domain warmupWarm a fresh sending domain on a staged volume ramp and watch inbox placement and spam signals daily. Pauses the ramp if placement drops, so you land in the inbox, not the promotions tab.Locked

Why now

Skills just became a format. The packs didn't exist yet.

Oct 16, 2025

Anthropic shipped Agent Skills: a folder with a SKILL.md that packages one workflow for Claude, Claude Code and the API.

Dec 18, 2025

Skills became an open standard for cross-platform portability. A skill written once travels, which means it can be packaged and shared.

The gap

The skills that actually work are scattered across gists and threads. There is no curated, battle-tested pack you can just install. That is the crate.

How it works

From crate to running workflow in minutes.

STEP 01

Pick a pack

Cold Outreach, Inbox Zero, or Idea Validation. Each is a set of named skills you can read in full before you buy.

STEP 02

Drop it into Claude

A pack is a set of SKILL.md folders. Copy them into Claude or Claude Code and your agent discovers them automatically. No account with us.

STEP 03

Your agent runs the workflow

Ask in plain language. The skill supplies the steps, the guardrails and the output format. You review and approve.

These are the workflows that run our studio.

Merrowby is a venture studio. Every skill in these packs came out of real work: outreach we send, inboxes we clear, and ideas we kill before they cost us. We packaged what worked. No user counts, no revenue claims, just the skills, written to a standard you can read line by line.

The quality bar
  • Every skill is plain, editable SKILL.md you own.
  • Guardrails and compliance gates are built in, not bolted on.
  • Two full skills are free, so you judge before you pay.
Free vs the pack

Two full skills are free. Here is what the $49 adds.

Free samples$0no email
  • Two complete SKILL.md files, fully readable: list building and inbox triage
  • The exact format, depth and guardrails every paid skill is held to
  • Yours to copy, edit and ship, or use as a template for your own
  • No email, no account, no card
The pack$49early access
  • Every skill in the pack, install-ready (five to seven per pack)

  • The whole pipeline runs end to end, not one step in isolation
  • Output schemas and guardrails wired in, not left as an exercise
  • You keep the files. No runtime, no seat fees, no lock-in

Same format on both sides. The free samples are the whole skill, not a teaser; the pack is the other skills plus the wiring that makes them run as one pipeline.

Early access

Questions

Fair questions, answered straight.

Because the format being open is the whole point, and it still takes real work to get one right. What you buy is the curation and the battle-testing: the exact steps, the edge cases, and the guardrails, wired together from workflows we run for real. Two full skills are free right here so you can judge the quality before you pay. Prefer to build your own? The free samples are a fair template to start from.

Anthropic's skills cover general tasks like documents and spreadsheets. SkillCrate packs are opinionated, end-to-end business workflows, a whole outreach pipeline rather than a single step, with the glue and the guardrails that a grab-bag of free skills leaves out.

A pack is a set of SKILL.md folders. Drop them into Claude or Claude Code and your agent picks them up automatically. There is no runtime to run, no account with us, and no lock-in. You keep the files.

They are starting points you own and edit, not black boxes. Every skill is plain markdown you can read and change in a minute. The two free samples above show exactly how specific and editable they are.

No. The pack leads with a compliance gate: CAN-SPAM, TCPA and Do-Not-Call scrubbing are built in, and a record that fails a check is dropped, not sent. It is built for permission-aware, value-first outreach, not blasting. Indicative, not legal advice.

If you already use Claude or Claude Code, you can install a pack by copying folders. No coding. The skills do the work; you review and approve each step.

This is early access. Your email locks the $49 founding price, which rises when packs open to everyone, and gets you the full install-ready pack the day it opens. No card now, no sales call. The two free samples above are yours to use with no email either way.

Open the crate before it's full-price.
