What it does

Social Card Gen is an agent skill from BrianRWagner/ai-marketing-claude-code-skills. Generate platform-specific social post variants (Twitter/X, LinkedIn, Reddit) from one source input. Works with or without Node.js script. Includes platform reasoning, quality review, and guardrails against cross-posting spam.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files (for example `.clawdhub/origin.json`, `README.md` and `SKILL-OC.md`).

It sits in AI & LLM Engineering, covering Social media graphics, Social media posts and Social publishing and cross-posting. It works with Node.js, X (Twitter), LinkedIn and Reddit. The repository describes itself as: Marketing frameworks that AI actually executes. Designed for Claude Code, but could be used for OpenClaw, etc.

When your agent uses it

  • Tasks that involve Social media graphics
  • Tasks that involve Social media posts
  • Tasks that involve Social publishing and cross-posting

Example prompts

  • “/social-card-gen”

Requirements

  • Node.js

Workflow steps

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

  1. Distill the Core Message
  2. Generate 3 Platform Variants

What it can do on your machine

Read from SKILL.md and the folder at commit f36b34f. 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

    Ships script files (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node
    • npm

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

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    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 Card Gen loads about 1.9k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 798 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k

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 798 words (~1,866 tokens).

“Transform one source message into platform-ready social copy for Twitter/X, LinkedIn, and Reddit.”
