  • SKILL.md covers Scope, Width / mobile, Images and Chrome / CTAs, plus 2 more sections
  • Reaches deltalytix.app

What it does

Marketing Email Chrome is an agent skill from hugodemenez/deltalytix. Reuse the August 2026 Deltalytix marketing and product-news email chrome lock when sending via Resend or Zeno. Use for latest-release broadcasts, fluid 100% width, hosted images, full-width CTAs, and send/copy rules. Do not originate campaign copy.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. The repository describes itself as: Trading journal with AI agents and dashboard with statistics.

When your agent uses it

  • Latest-release broadcasts
  • Fluid 100% width
  • Full-width CTAs
  • Send/copy rules

Example prompts

  • “/marketing-email-chrome”

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. After the first content block (after the first screenshot, not under the H1).
  2. After the sign-off.

What it can do on your machine

Read from SKILL.md and the folder at commit 1ed4c73. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are html and css).

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • deltalytix.app

    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

Marketing Email Chrome loads about 1.5k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 470 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 470 words (~1,452 tokens).

“Lock for Zeno and anyone sending marketing or product-news mail through Resend.”
