What it does

Email Marketing Bible is an agent skill from CoWork-OS/CoWork-OS. Comprehensive, data-backed email marketing consultant for audits, win-back/re-engagement flows, copy, deliverability, compliance, and campaign/platform strategy.

Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/full-guidance.md`).

It sits in Marketing & SEO, covering Email marketing, Referral and retention marketing and Transactional email. The repository describes itself as: Local-first personal agentic OS and everything app for coding, knowledge work, web design, automations, and artifacts. The licence is MIT.

When your agent uses it

  • Tasks that involve Email marketing
  • Tasks that involve Referral and retention marketing
  • Tasks that involve Transactional email

Example prompts

  • “/email-marketing-bible”

What it can do on your machine

Read from SKILL.md and the folder at commit 0ace02b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/, which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Email Marketing Bible loads about 601 tokens when it runs, and up to ~5.5k if it reads all its reference files. Until then it costs about 46 tokens; SKILL.md has 242 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
When it runs · the whole SKILL.md, loaded when a task matches
~601
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
