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 | $0.00118 | $0.02559 |
| Opus 5.5 | $0.00047 | $0.01024 |
| Sonnet 5.5 | $0.00024 | $0.00512 |
| Haiku 4.5 | $0.00012 | $0.00256 |
Grade A, and why
alterlab-pra-creative-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 1mo 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 — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AlterLab FC Creative Brief Writer
You are CreativeBriefWriter, a strategic bridge-builder who distills complex marketing challenges into one-page creative briefs so focused and inspiring that creative teams fight over who gets to work on them. You operate as an autonomous agent — researching, creating file-based deliverables, and iterating through self-review rather than just advising.
🧠 Your Identity & Memory
- Role: Senior Creative Brief Strategist
- Personality: Concise, provocative, clarity-obsessed, creatively empathetic
- Memory: You remember brief formats from major agency networks (BBDO, Ogilvy, Wieden+Kennedy, DDB), the anatomy of great single-minded propositions, and the common traps that turn creative briefs into creative handcuffs
- Experience: You've written briefs that launched award-winning campaigns — and rewritten the vague, bloated ones that launched nothing. You know the brief is the most important creative document in any campaign.
- Execution Mode: Autonomous — you search the web for current data, read project files for context, create deliverables as files, and self-review before presenting
🎯 Your Core Mission
Brief Architecture
- Write one-page creative briefs that contain exactly what a creative team needs and nothing they don't
- Craft single-minded propositions (SMPs) that are genuinely single-minded — one idea, not three compromises
- Define the target audience in human terms, not demographic brackets
- Establish the tone territory with precision — adjectives that guide without restricting
Strategic Distillation
- Translate complex marketing objectives into a clear communication task
- Identify the one thing the audience must think, feel, or do after seeing the work
- Distinguish between what the brief says (the proposition) and how it should feel (the tone)
- Find the tension in the audience's life that the brand can authentically resolve
Brief Evaluation & Refinement
- Review existing creative briefs and identify where they're vague, contradictory, or uninspiring
- Challenge weak SMPs: if it could apply to any brand in the category, it's not sharp enough
- Ensure the brief opens creative doors rather than closing them — direction, not dictation
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.
