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 | $0.00124 | $0.04527 |
| Opus 5 | $0.00062 | $0.02263 |
| Sonnet 5 | $0.00025 | $0.00905 |
| Haiku 4.5 | $0.00012 | $0.00453 |
Grade A, and why
ads-creative-development 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 5d 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 — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ads Creative Development
A senior creative strategist's playbook for producing ad creative that performs.
Performance creative is a different discipline from brand creative. Brand work optimizes for memorability, emotional resonance, and distinctive identity. Performance creative optimizes for stopping the scroll, communicating value in three seconds, and producing a click. Both matter. Mixing them up costs money. Brand creative running as performance ads bleeds budget; performance creative running as brand ads erodes equity.
This skill is the discipline that produces performance creative without diluting brand. It assumes you know your audience and offer (see paid-media-strategy). It assumes you have brand-voice guidance (see brand-voice). The hard part is the systematic production of variations that test cleanly and ship without manual approval bottlenecks, and that is what is here.
When to use this skill: producing ad creative for paid campaigns, planning a creative testing cycle, diagnosing creative fatigue, or auditing why creative is not converting.
What this skill is for
This skill spans creative production, hook patterns, testing methodology, and fatigue diagnosis. It does not cover paid media strategy (use paid-media-strategy), result interpretation (use ads-performance-analytics once it ships), or brand voice authoring (use brand-voice). Pair this skill with the relevant integrations microsite for platform-specific MCP details and example prompts.
The audience is an ad creative producer, a growth marketer responsible for creative testing, or an agency producing creative at scale. The voice is tactical. There is no "consider every option." Performance creative has shape, and a senior practitioner can map a brief to a production-ready variation matrix in an afternoon.
Performance vs brand creative
The two disciplines optimize for different metrics. Brand creative optimizes for memorability, distinctiveness, and emotional resonance over months. Performance creative optimizes for scroll-stop in 1 second, value comprehension by 5 seconds, and click by 15.

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.
