What it does

Substack Note Generator is an agent skill from aiskilloftheweek/claude-ai-skill-of-the-week. Generate optimized Substack Notes starting from long-form content.

Its SKILL.md is about 3k 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. It works with Substack. The repository describes itself as: Curating the greatest Claude Skills that actually change how you work.

When your agent uses it

  • Tasks that involve Newsletters

Example prompts

  • “/substack-note-generator”

Workflow steps

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

  1. Analyze Input & Choose Note Type
  2. Apply Structural Formula
  3. Generate Note
  4. Format for Substack

What it can do on your machine

Read from SKILL.md and the folder at commit f3b155c. 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.

    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

Substack Note Generator loads about 3k tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 1,161 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~3k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,161 words (~3,036 tokens).

“name: substack-notes description: Generate high-performing Substack notes using proven structural patterns and psychology while maintaining your authentic voice.
