From the author
Agent guide for operating Sequenzy. Use when Codex needs to authenticate, inspect identity, manage subscribers, create or edit campaigns/sequences/templates, generate draft email content, send a transactional email, read delivery stats, or decide whether a requested Sequenzy workflow is currently supported. Prefer the CLI when it is implemented, and fall back to the dashboard or direct API use when the current CLI surface is only partial.

Install

Each tab says whether it installs commit a110309, the one we checked, or the latest version.

No tab for your agent? Use Any agent for OpenCode, Goose, Windsurf (Devin Desktop), Zed, Roo Code, Factory Droid, Junie, Amp and Antigravity, and Claude Code for Cline. Kiro needs the folder copied by hand.

Pinned to commit a110309, the one we checked.

From your project's root folder:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/davepoon/buildwithclaude.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin a1103092fa571c032ae3e706433505ce0d6327bc &&
  git -C "$tmp" sparse-checkout set -- plugins/all-skills/skills/sequenzy-email-marketing &&

  cp -R "$tmp"/plugins/all-skills/skills/sequenzy-email-marketing/. .claude/skills/sequenzy-email-marketing/ &&
  rm -rf "$tmp"

What it can touch

From the files and frontmatter at commit a110309. This is how much a skill can do, not whether it is risky.

What it can touch: Scripts or outside hosts

  • Runs shell commands

    Its instructions or files give the agent commands to run on your computer.

  • Names web addresses

    It mentions outside web addresses the agent may visit. We list them but don't follow them.

Pattern check

Pattern check: nothing flagged · commit a110309 · 27 Oct 2026

We checked every text file in this skill, at commit a110309 on 27 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

How the check worksReport an incorrect finding

Outside links we did not follow

  • https://sequenzy.com
  • https://api.sequenzy.com

Format check

Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.

  • Agent Skills specPasses with warnings

    The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.

    • Warning

      Fields outside the spec: category. Uploads to the Claude apps and API, and the spec's validator, reject the file; most agents ignore these fields. O1

      Fix: Delete them for a portable skill, or keep them if you only target the agents that read them.

    • Note

      There is no license field, so readers can't tell whether they may reuse the skill. O2

      Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.

    • Note

      Reference files over 100 lines with no table of contents at the top: references/command-reference.md (479 lines) and references/use-cases.md (493 lines). B5

      Fix: Add a short list of the sections at the top of each.

  • Claude CodePasses

    Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.

    • Note

      Claude Code ignores fields it doesn't know: category. O1

      Fix: Check the spelling against Claude Code's field list, or delete them.

    • Note

      Reference files over 100 lines with no table of contents at the top: references/command-reference.md (479 lines) and references/use-cases.md (493 lines). B5

      Fix: Add a short list of the sections at the top of each.

  • Claude apps & API uploadFails

    Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.

    • Error

      Upload and packaging fail on fields outside the spec: category. O1

      Fix: Delete them, and keep your own data under metadata as text values.

    • Note

      The description is 442 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4

      Fix: If the claude.ai upload refuses it, trim the description to 200 characters.

    • Note

      Reference files over 100 lines with no table of contents at the top: references/command-reference.md (479 lines) and references/use-cases.md (493 lines). B5

      Fix: Add a short list of the sections at the top of each.

  • OpenAI (Codex & API)Passes with warnings

    Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.

    • Warning

      Fields outside the spec: category. Codex ignores them; OpenAI doesn't say whether its upload accepts them. O1

      Fix: Delete them, or move your own data under metadata as text values.

  • VS Code & CopilotPasses

    VS Code reads skills one folder below .github/skills, .claude/skills or .agents/skills and falls back to the folder name when the name is missing or differs; GitHub's Copilot docs require the exact name SKILL.md.

    • Note

      VS Code ignores fields it doesn't support: category. O1

      Fix: Delete them unless another agent you target reads them.

    Teaches when to recall from long-term memory before acting and when to save durable decisions, corrections and failures afterwards.

Works with any memory backend: a folder of Markdown files, a local MCP server, or a managed service.
