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 | $0.00084 | $0.00757 |
| Opus 5 | $0.00042 | $0.00378 |
| Sonnet 5 | $0.00017 | $0.00151 |
| Haiku 4.5 | $0.00008 | $0.00076 |
Grade A, and why
testimonials-generator 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 12d 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.

Initial Assessment
Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for customer personas and industries.
Identify:
- Content type: Text quotes, video, case studies
- Placement: Product pages, pricing, hero, dedicated page
- Audience: B2B vs B2C; industry/role relevance
Content Formats
| Format | Effectiveness | Best For |
|---|---|---|
| Video | Highest; 77% say it influences buying | Key landing pages |
| Text + photo | Versatile; easy to implement | Product, pricing |
| Case study | Deep credibility; specific outcomes | B2B, high-value |
| Star ratings | Quick trust signal | E-commerce |
Video: 95% message retention vs 10% for text.
Best Practices
Content

- Before/after narratives for emotional connection
Design Guidelines
- Clean layouts; readable typography
- Engaging visuals; avoid clutter
- Mobile-optimized; fast loading
- Carousel for multiple testimonials; see carousel for design and accessibility
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.
