What it does

Newsletter is an agent skill from EmertonData/glide. Drafts the monthly GLIDE LinkedIn newsletter (and, on request, its companion punchy LinkedIn post). Use this skill whenever the user asks to write, draft, or prepare the monthly newsletter, the LinkedIn issue, or the next GLIDE newsletter — even if phrased informally ("let's do the newsletter", "time for the monthly post", "draft this month's issue").

Its SKILL.md is about 3.8k 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 Writing & Content, covering Newsletters and Social media posts. It works with LinkedIn. The repository describes itself as: Helping humans ride the GenAI evaluation wave.

When your agent uses it

  • The user asks to write
  • Prepare the monthly newsletter
  • The LinkedIn issue
  • The next GLIDE newsletter — even if phrased informally (lets do the newsletter

Example prompts

  • “s do the newsletter”
  • “time for the monthly post”
  • “draft this month”
  • “/newsletter”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Auto-research (no user input needed)
  2. Information gathering
  3. Deep research
  4. Write the newsletter
  5. Companion post (only if requested in Phase 2)

What it can do on your machine

Read from SKILL.md and the folder at commit 21a9553. 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

    Shell commands in SKILL.md call:

    • gh

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

  • Network

    Links to these hosts (documentation or services it may open):

    • science.org

    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

Newsletter loads about 3.8k tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 2,245 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~3.8k

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 2,245 words (~3,847 tokens).

“This skill produces newsletters/YYYY-MM.md — the draft of the monthly GLIDE LinkedIn newsletter — and, if the user wants it, a second file newsletters/YYYY-MM-linkedin-post.md, a shorter and punchier companion post in a different register (see the "LinkedIn post companion" section…”
