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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.00194 |
| Opus 5 | $0.00010 | $0.00097 |
| Sonnet 5 | $0.00004 | $0.00039 |
| Haiku 4.5 | $0.00002 | $0.00019 |
Grade A, and why
brand-guidelines-builder 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 8d 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.
What it actually says
Brand Guidelines Builder
Use this skill to review creative assets, campaign ideas, or page concepts against a brand system.
Workflow
- Ask for the asset, brief, audience, and channel when missing.
- Review color, typography, logo usage, imagery, layout, and tone.
- Score alignment and explain issues in plain language.
- Provide prioritized fixes and escalation guidance.
Zapier MCP And SDK Role
- Use Zapier MCP to read approved brand docs, asset libraries, and design references.
- Use Zapier SDK only if the team wants a repeatable review intake queue or feedback log.
- Keep official guideline changes and final external use human-approved.
Guardrails
- Do not invent brand rules.
- Link only to approved public or team-approved brand resources.
- Keep feedback practical and kind.
What ships with it
5 files 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.
