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 | $0.00062 | $0.00765 |
| Opus 5 | $0.00031 | $0.00382 |
| Sonnet 5 | $0.00012 | $0.00153 |
| Haiku 4.5 | $0.00006 | $0.00076 |
Grade A, and why
brief-creative 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 11d 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brief creative work
Turn a marketing decision into a production brief that a designer, developer, photographer, or video creator can execute without guessing.
Define the communication job
Establish:
- target audience and viewing context;
- action or belief the asset must create;
- one message hierarchy;
- product mechanism and proof to make visible;
- destination and campaign promise;
- format, placement, dimensions, duration, language, and accessibility constraints;
- available source assets and factual restrictions.
Ask only when a missing decision would materially change the concept. Label reasonable assumptions.
Choose one concept
Express the concept as a concrete relationship between message, product evidence, and form. A concept is not a mood-board adjective. Explain why the chosen form makes the claim easier to understand or believe.
Prefer:
- product behavior, demonstration, comparison, or artifact as evidence;
- one dominant idea and deliberate hierarchy;
- native composition for the destination;
- readable type, useful contrast, captions, and reduced-motion alternatives;
- modular production that supports the required variants.
Reject arbitrary gradients, stock symbolism, decorative dashboards, fake UI, fabricated metrics, and visual novelty disconnected from the message.
Specify the production
Deliver:
- communication job and audience moment;
- single concept and why it works;
- frame, section, shot, or scene sequence;
- exact copy hierarchy and required product evidence;
- art direction: composition, imagery, typography behavior, color roles, and motion;
- asset inventory, source-of-truth files, and production constraints;
- variant matrix for formats that genuinely need different composition;
- accessibility and localization requirements;
- acceptance criteria and rejection conditions.
For a landing page, specify scan order, sections, proof placement, objection handling, and responsive behavior. For video, specify hook, beat timing, visual proof, captions, audio role, CTA, and end state. For product previews, distinguish representative mockups from shipped functionality.
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.
- 11d ago First seen · 86 lines · 62 tokens per session scan A 1e017386eeeb
brief-creative is a skill published in the GitHub repository forsvn-labs/meta-skills (14 stars, last pushed 1mo ago), licensed MIT. It adds 62 tokens to every session and 765 once invoked, about $0.0003 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 2026-08-30.
