agent-brain: Skill for Claude Code

.agents/skills/draft/SKILL.md

draft is a skill for Claude Code from Railly/agent-brain. It costs 11 tokens per session (908 once invoked), scanned A, original, MIT.

A content-writing workflow that turns a stored idea into a draft for formats such as tweets, threads, LinkedIn posts, blog articles, or video scripts. It uses a “Shipping Bible,” a set of writing principles and templates.

In plain words
What is it for?
Use it to browse ideas, select one, and create a dated Markdown draft with a hook, story, key points, call to action, and launch checklists.
Why use it?
It removes the need to choose an idea, format, structure, and checklist from scratch. It gives unfinished ideas a consistent place and shape.

Skill for Claude Code

This is Railly/agent-brain's own configuration. It tells Claude Code how to work on agent-brain itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-brain configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

draft scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

    • Thread (multi-post story)
    • LinkedIn (longer story format)
    • Blog (full article)
    • Video script (demo/tutorial)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
