What it does

Article Writing is an agent skill from c0x12c/ai-toolkit. Write blog posts, guides, tutorials, and long-form content. Sounds like a real person, not AI. Use when the user wants polished written content.

Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `examples.md`).

It sits in Writing & Content, covering Blog and article writing.

When your agent uses it

  • The user wants polished written content
  • Tasks that involve Blog and article writing

Example prompts

  • “/article-writing”

Workflow steps

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

  1. Start with something concrete: example, number, story, or code block.
  2. Explain after the example, not before.
  3. Short, direct sentences.
  4. Use real numbers when you have them.
  5. Never make up facts, company data, or quotes.

What it can do on your machine

Read from SKILL.md and the folder at commit 96b2c9d. 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

Article Writing loads about 878 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 517 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~40
When it runs · the whole SKILL.md, loaded when a task matches
~878

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 517 words (~878 tokens).
