Sequenzy
Overview
Use this generic skill when the user refers broadly to Sequenzy and no narrower skill is obviously better. For email-marketing/product work, prioritize sequenzy-email-marketing: campaigns, subscribers, lists, tags, segments, templates, sequences, transactional email, delivery stats, dashboard URLs, CLI/MCP behavior, and currently-supported workflow checks. Prefer the sequenzy CLI for supported workflows, treat packages/mcp/src/tools/index.ts as the MCP source of truth when the task goes through MCP tools, and explicitly call out when a requested workflow is not wired in the current implementation.
Ground Rules
Treat packages/cli/src/index.tsx as the source of truth for which commands are actually wired.
Treat packages/cli/src/commands/ and packages/cli/src/api.ts as the source of truth for CLI behavior, payload shape, and API routes.
Treat packages/mcp/src/tools/index.ts as the source of truth for MCP tool names, arguments, and preflight validation.
Do not promise support for commands or tools that only appear in docs or --help text without an attached implementation.
Prefer sequenzy login for interactive auth and SEQUENZY_API_KEY for automation.
Prefer inspection before mutation whenever the workflow allows it.
Supported Workflows
Read references/use-cases.md before executing anything non-trivial. The currently implemented CLI flows are:
login and logout
local auth/session check with whoami
account inspection with account
company inspection or creation with companies list|get|create
stats overview or stats by campaign/sequence ID
subscribers list, add, get, and remove, with list fetching every page by default and supporting tag, segment, and list filters
lists list, create, update, delete, add-subscribers, remove-subscribers, and import alias for bulk list population from emails, JSON, CSV, or newline files
tags list, create, update, and delete, with bare sequenzy tags still listing tag definitions for backwards compatibility
segments list, create, update, delete, and count, including --match any, nested filter roots, custom event filters, and saved-segment composition filters
templates list, get, create, update, and delete, with list supporting label filters and create/update accepting labels, raw HTML, or Sequenzy block JSON
campaigns list, get, create, update including label and reply-to updates, schedule, and test, with list supporting label filters, create accepting labels plus raw HTML, Sequenzy block JSON, or prompt-generated content, update accepting labels plus raw HTML or Sequenzy block JSON, and schedule returning a review preview link
campaign lifecycle control with campaigns cancel (stops scheduled, paused, waiting-approval, or sending campaigns immediately, no confirmation prompt), campaigns pause and for an active send (resume supports ), (blocked while sending, scheduled, or paused - cancel first), and with
Unsupported Or Placeholder Workflows
Treat missing subcommands as unsupported even when the noun exists. The main remaining gap is campaign immediate send: there is no "send now" command, so schedule the campaign with a near-future --at timestamp instead. Bulk list population is supported through sequenzy lists add-subscribers and its sequenzy lists import alias, not through subscribers add.
Execution Pattern
Check auth first with sequenzy whoami or by verifying SEQUENZY_API_KEY is set.
Pick the narrowest command that matches the use case.
Validate IDs, recipient email, subject, template, or content input before issuing a mutation.
Surface CLI limitations directly instead of inventing a workaround.
If the workflow is unsupported in the CLI, say whether the next-best path is the Sequenzy dashboard or direct API use.
When you create, inspect, or schedule a campaign, sequence, template, or company and the user may want to review/edit it, surface the dashboard URL from url, previewUrl, or appUrls in the tool/CLI output. If needed, generate it with sequenzy urls or MCP get_app_urls.
Destructive commands (delete, delete-variant, cancel-invitation, and similar) prompt for confirmation. Pass --yes (or -y) to skip the prompt; --yes is required when stdin is not a TTY, which covers most agent and CI runs.
webhooks create returns a one-time signing secret. Surface it to the user immediately - it cannot be retrieved later.
Call out implementation caveats that matter operationally, such as whoami using cached local auth state, sequence creation supporting both --goal and explicit step modes, explicit discount steps requiring Stripe before activation, generated sequences being capped at 10 emails, campaigns test being a stubbed success path in the current backend, and conditional email content requiring block JSON rather than raw HTML.
Dashboard URLs
Use SEQUENZY_APP_URL as the dashboard base when it is set; otherwise default to https://sequenzy.com.
Prefer actual URLs returned by the CLI/MCP result:
ab-tests list, get, stats, restart, update-variant, create, add-variant, delete-variant, and delete; create/add-variant/delete-variant/delete work on campaign A/B tests in draft status, variant A is the protected control, and restart reruns a finished sequence A/B test
MCP template and campaign tools support labels on list/create/update; MCP update_campaign also supports replyTo and replyProfileId, and MCP schedule_campaign schedules draft or already scheduled campaigns
MCP search_subscribers supports list filters through list, listId, or listName; MCP add_subscribers_to_list accepts up to 500 emails per call
sequences list, get, create, update, enable, disable, delete, enroll, and cancel-enrollments, including explicit discount action steps, cancellation by subscriber ID or event-property field values, and update branch insertion with tag, list, segment, event, clicked-link, and field conditions; event and clicked-link branch checks can use activityScope (this_sequence, previous_email, ever)
manual sequence enrollment with sequences enroll from emails, JSON, or files, optionally at a specific node with --target-node-id, reporting enrolled, skipped, and not-found subscribers
team list, invite with --role admin|viewer and owner-only --billing-access, and cancel-invitation
inbox list with status, search, unread, and pagination filters, get, reply including internal notes with --note, close, reopen, and mark-read
webhooks list, create, update, delete, test, deliveries, and replay for outbound webhook endpoints, with create printing the signing secret exactly once
AI generation with generate email, generate sequence, and generate subjects
dashboard URL generation with CLI urls, MCP get_app_urls, and appUrls/url fields on campaign, sequence, template, and company results
websites list, add, check, and guide
products list, sync, attach-file, and detach-file for digital product delivery, with attach-file --file uploading local files via presigned URLs; attached files are exposed on saas.purchase events as {{event.download.url}} / {{event.download.name}} (MCP: list_products, attach_product_file, remove_product_file, sync_products)
API key creation with api-keys create
send one transactional email by template or raw HTML
