AI copilot for lifecycle and CRM ops on Braze, Klaviyo and Iterable. Read-only.
These three are never merged into one score: opinions, measurements and popularity are different things.

The AI copilot for lifecycle and CRM operations on Braze, Klaviyo and Iterable. Ship campaigns faster. Break nothing that's live.
A Claude Code plugin for lifecycle, CRM and marketing-ops teams who build campaigns by hand. It knows your live account and your team's rules. It is read-only: it never sends or edits anything.
No account and no Claude Code needed, just Node.js 20+. This checks four sample emails that ship with the package:
npx crm-lifecycle-ops check --demo
Then point it at your own templates: npx crm-lifecycle-ops check path/to/emails. That covers emails. The plugin below adds the rest: every channel, your live account, what a change will break, and build steps.
| Try | ||
|---|---|---|
| Plan and build faster | Click-by-click build steps in your platform's terms, with your naming and UTMs | /build-plan |
| Change safely | See what a change to a segment, field or shared block will break, before you make it | /what-breaks |
| Send with confidence | Every message on every channel, checked as every kind of customer | /check-campaign |
| Prove the impact | Delivery health after launch, plus problems caught and hours saved | /ops-report |
Needs Claude Code and Node.js 20+.
/plugin marketplace add har5h98/crm-lifecycle-ops
/plugin install crm-lifecycle-ops@crm-lifecycle-ops
Then try it on the built-in demo account. No platform access needed:
/refresh demo loads a fictional brand's Braze workspace./check-campaign Price Drop Alert checks a whole campaign./what-breaks loyalty_tier shows what a change would affect.When you're ready for your own account:
/setup teaches it your team's rules (about five minutes, or paste an email you like and it learns from that)./connect adds a read-only key. Keys go in the plugin's settings and your system's secure storage, never in chat.Using Cursor, Claude Desktop or another MCP client?
The engine is also on npm, so any MCP client can run it. The slash commands are Claude Code skills, so elsewhere you ask in plain words ("check this email", "what breaks if I rename loyalty_tier?").

Leave env out to use the demo account. Every setting is listed in server.json.
Check email templates in CI
The same checks run from a terminal, so a pipeline can stop a broken email before anyone launches it. It exits 1 on a blocking problem (or on warnings too, with --fail-on warn), and uses your house rules.
npx crm-lifecycle-ops check emails/ --rules team-rules.json
# .github/workflows/email-qa.yml
on: pull_request jobs: email-qa: runs-on: ubuntu-latest steps:
--help lists the options (--platform, --subject, --transactional, --json). The template language is detected per file.
Early alpha. Everything works on the demo account and against mocked API responses. It hasn't been
field-tested on real accounts yet. If a result looks wrong,
/report-problemturns it into a test and a fix.
Real output from the demo account:
/check-campaign Price Drop Alert 🔴 Don't send. 1 blocking problem
fail links.non-production-host "See items" points at staging.fernbrook.example warn personalization.dangling-punct. Someone with no first name on file sees "Hi ," warn links.utm-inconsistent 1 of 2 links carry UTM tags; "Help" doesn't warn html.img-missing-alt 1 image has no alt text
/check-sms Flash Sale Text 🟡 Fix before sending
warn sms.unicode "’" and "—" switch the text to Unicode: 70 characters per segment, not 160. Swap ’ → ' and — → - warn sms.too-many-segments Up to 3 billed segments; house limit is 2 warn sms.no-opt-out No "Reply STOP to opt out"
Code makes every pass/fail call, never AI. Claude adds a labelled, advisory review (subject line, CTA, tone) on top. Need a record for the launch ticket? Ask /check-campaign for a QA sign-off report: a Markdown file with every finding, what couldn't be verified and a reviewer sign-off, ready to paste into Jira, Slack or Notion.

What "check" covers, by channel
| Channel | Catches |
|---|---|
Broken Outlook blocks, unclosed tables, missing alt text, Gmail clipping; a preheader that's missing, repeats the subject or reads "View in browser"; staging or malformed links, http://, inconsistent UTMs, broken pages (live check); missing unsubscribe (skipped for transactional mail) | |
| Accessibility (email) | Missing lang, "click here" links, image-only links with no alt text, layout tables screen readers read as data, text under 12px |
| Push | Title and body length for your *longest* customer names, line breaks that hide titles on iOS, deep links, Android's required title (Braze) |
| SMS | Billed segments the way carriers count them, the exact character that switches a text to Unicode, opt-out wording, sender name, each platform's limits |
| In-app | Body length, buttons and their links, click-through destination, HTML structure |
| Content cards | Title and message length, card link and image destinations |
| Webhooks | Missing or staging URLs, keys written into the URL, JSON bodies that break when a name contains a quote |
| Personalization (all) | Renders every message for a *complete*, *empty*, *long-values* and *accented-name* customer (or your own): Hi , blanks, literal null, leftover {{ }}, template errors, Iterable comparisons that silently skip the send |
| Campaigns & journeys | Audience and conversion event, naming convention, dead-end branches, unreachable steps, empty message steps |
Braze Liquid, Klaviyo's template language and Iterable Handlebars are supported. Platform tags that can't run locally (coupon codes, catalog lookups, Connected Content) are reported as *not verified*, never as passing or failing. Full list with ids: src/checks/catalog.ts.
Your rules, not just ours
What's "wrong" depends on the team, so checks come in three layers:
| Layer | Examples | Can a team change it? |
|---|---|---|
| Locked: wrong for everyone | No unsubscribe, template syntax that doesn't render, broken links | No |
| Defaults: sensible everywhere | Missing alt text, http:// links, Gmail clipping, mixed UTM tagging | Re-grade or turn off |
| House rules: your conventions | Spelling, date format, brand terms, banned phrases, approved domains and senders, UTM naming, footer, subject length, name fallback, naming convention, test customers | Set in /setup |
"That's fine for us" becomes a recorded exception with a reason (/house-rules), which is different from "the tool is wrong" (/report-problem). Teams share one rulebook by setting the same Shared rules file in the plugin's settings.
What it can't see (yet)
Every result says what it couldn't verify, and every dependency says how it's known (*confirmed by the API*, *read from the template*, *read from the segment description*, *seen on screen*).
/what-breaks lists those as "can't rule out" and can read them from your Braze dashboard via Claude in Chrome, with your OK./build-plan and /edit-plan tell you how; /bulk-edit previews only.It never sends messages, never
