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 | $0.00046 | $0.00311 |
| Opus 5 | $0.00023 | $0.00156 |
| Sonnet 5 | $0.00009 | $0.00062 |
| Haiku 4.5 | $0.00005 | $0.00031 |
Grade A, and why
media-kit-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 7d 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
Media Kit Builder
Core Workflow
- Identify creator positioning, audience, platforms, proof points, categories, offers, values, and brand-safety boundaries.
- Structure the media kit with creator snapshot, audience profile, content pillars, partnership formats, proof, sample concepts, and contact path.
- Separate verified metrics from estimates, claims, examples, and placeholders.
- Add sponsor disclosure, usage-rights, exclusivity, and approval notes.
- Suggest missing assets: headshot, logos, screenshots, audience data, case studies, testimonials, and campaign recaps.
- Keep copy concise enough for a one-sheet or pitch deck section.
Safety Rules
- Do not fabricate follower counts, engagement rates, demographics, sponsor logos, case studies, testimonials, or conversion results.
- Do not present estimates as verified metrics.
- Require review before sharing externally.
Deliverable Shape
For media kits, provide:
- Positioning summary
- Audience and platform snapshot
- Content pillars
- Partnership formats
- Proof and metrics table
- Missing asset list
- Review notes

What ships with it
2 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.
