onboarding-brand-brief

onboarding-brand-brief is a skill for Claude Code from moses607/socialforge. It costs 128 tokens per session (1,108 once invoked), scanned A, original, MIT.

A first-run setup that records a creator’s audience, position, offer, platforms, and writing voice in a reusable brand brief. It can also study the creator’s existing posts or admired creators to describe the voice.

In plain words
What is it for?
Defining a niche, unique angle, offer, growth goal, target platforms, and writing style before creating hooks, personas, captions, or content calendars.
Why use it?
It gives later content work a clear source of audience and style information instead of relying on generic assumptions. The brief can be reused across other social-media tasks.

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

onboarding-brand-brief 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 9d 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.

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Onboarding Brand Brief

Everything downstream — hooks, personas, calendars, captions — degrades to generic mush without a foundation the model can anchor on. A brand brief is not branding fluff; it is a compression of five decisions (who you serve, why you, what you sell, where, and how you sound) into a block short enough to prepend to every generation. Extract it once, reuse it forever. The single highest-leverage step is voice training: a model that has read five of the creator's real posts stops writing "in today's fast-paced world" and starts writing like them.

Method: interrogate the five pillars

Ask these in order. One question at a time. Push back on vague answers — "fitness" is not a niche, "busy moms who want to lift heavy without a gym" is.

  1. Niche + sub-niche. Force specificity. Broad niche = the room; sub-niche = the corner they own. Reject anything you could put on a billboard for a competitor.
  2. Positioning / unique angle. Finish this sentence with them: "Unlike everyone else in [niche], I ___." If they can't, probe their contrarian take, origin story, or unfair advantage.
  3. Offer + primary goal. What is the money or growth event? Followers, email leads, product sales, bookings? Name ONE primary goal and the metric that proves it. Secondary goals get logged but never drive the strategy.
  4. Platforms. Where do they post now and where do they want to. Rank them. Downstream skills adapt format per platform.
  5. Voice attributes. Pull 3 adjectives, but make them earn it — "professional" is banned. Push for tension pairs like "blunt but warm" or "nerdy but irreverent".

Method: voice training from real posts

  1. Ask for 3-5 of their best-performing or favorite posts — their own, or admired creators they want to sound like (flag which).
  2. Extract three layers explicitly: tone (emotional default — deadpan, hyped, tender), lexicon (recurring words, slang, jargon, signature phrases, emoji habits), rhythm (sentence length, one-liners vs paragraphs, use of line breaks, punctuation quirks).
  3. Derive a do-words / don't-words list: words that sound like them, and words that would break the illusion (corporate filler, hashtag-speak, AI tells like "delve", "elevate", "unlock").
  4. Write one 2-sentence sample in their voice and ask "does this sound like you?" Iterate until yes. Do not finalize the brief on an unconfirmed voice.
