What it does

Social Post Writer is an agent skill from evolution-foundation/evo-nexus. When the user wants to write a social media post for LinkedIn, Twitter/X, Threads, or Bluesky. Also use when the user mentions 'write a post,' 'draft a post,' 'LinkedIn post,' 'tweet,' 'Threads post,' 'Bluesky post,' 'social media post,' 'help me write,' or shares a topic and wants it turned into a post. For multi-part content, see social-thread-writer. For carousels, see social-carousel-writer. For opening lines specifically, see social-hook-writer.

Its SKILL.md is about 2.4k 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 Social media posts. It works with LinkedIn, Bluesky and X (Twitter). The repository describes itself as: The open source operating system for AI-powered businesses.

When your agent uses it

  • Wants to write a social media post for LinkedIn
  • The user mentions write a post
  • Social media post
  • Shares a topic and wants it turned into a post

Example prompts

  • “write a post,”
  • “draft a post,”
  • “LinkedIn post,”
  • “/social-post-writer”

Workflow steps

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

  1. Select or generate a hook — use patterns from social-hook-writer (contrarian, question, story opener, statistic, list preview, bold claim…
  2. Draft the post body — use the user's voice from the context file. Mirror their vocabulary, sentence rhythm, and punctuation habits. Do not…
  3. Add the CTA — make it specific to the content type
  4. Format for readability — use generous white space to make the post scannable and easy to read. Apply one of these spacing patterns
  5. Apply platform-specific rules — hashtags, character limits, and link placement per platform.
  6. Generate variants if requested — offer 2-3 versions with different hooks or angles when the user wants options.

What it can do on your machine

Read from SKILL.md and the folder at commit 7f5dd76. 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

Social Post Writer loads about 2.4k tokens when it runs. Until then it costs about 118 tokens; SKILL.md has 1,114 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~118
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k

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 1,114 words (~2,355 tokens).

“You are an expert social media writer who crafts platform-native posts that stop the scroll, match the user's authentic voice, and drive real engagement. You know the structural rules, character limits, and cultural norms of every major platform — and…”
