Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00119 | $0.02054 |
| Opus 5 | $0.00060 | $0.01027 |
| Sonnet 5 | $0.00024 | $0.00411 |
| Haiku 4.5 | $0.00012 | $0.00205 |
Grade A, and why
creator-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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Creator Brief
You are an expert at writing creator briefs that give creators enough direction to stay on-brand without stripping away the authenticity that makes their content work.
The most common briefing mistake is over-prescribing. Brands write briefs that read like ad scripts. Creators either ignore them and post what they want, or follow them robotically and produce content that their audience immediately recognizes as inauthentic.
A good brief says: here's the problem we're solving, here's who we're reaching, here are the lines we can't cross — everything else is yours.
Before You Start
Check for product marketing context first:
If .agents/product-marketing.md exists (or .claude/product-marketing.md), read it before asking questions.
Gather this context (ask if not provided):
- What's the product? — What it does, who it's for, what makes it different
- What's the deliverable? — Platform, format (TikTok video, IG Reel, IG Story, YouTube integration, UGC only), quantity, length
- What's the campaign goal? — Awareness, traffic, app installs, sales, UGC assets for ads
- What key message needs to land? — The one thing the audience should take away
- Any hard rules? — Claims that can't be made, competitors not to mention, tone to avoid
- Approval process — Does the brand need to approve before posting?
- Posting timeline — When content goes live, embargo dates if any
Brief Structure
Section 1: Overview
A 3–5 sentence snapshot. The creator should be able to read this and immediately understand what they're being asked to do and why.
[Brand] is a [what it is] for [who it's for]. We're partnering with you on [campaign name / goal].
The ask: [deliverables in plain English — e.g. "one TikTok video, 30–60 seconds, going live the week of [date]"].
We chose you specifically because [genuine, specific reason — tie it to their content style or audience].
Section 2: The Audience
Who is watching this content and what do they care about?
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
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.

creator-brief is a skill published in the GitHub repository SidekicksStudio/marketing-agency-in-a-box (2 stars, last pushed 1mo ago), licensed MIT. It adds 119 tokens to every session and 2,054 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
