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 | $0.00031 | $0.00278 |
| Opus 5 | $0.00015 | $0.00139 |
| Sonnet 5 | $0.00006 | $0.00056 |
| Haiku 4.5 | $0.00003 | $0.00028 |
Grade A, and why
mocksmith 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 2d 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
MOCKSMITH — Test Data & Fixture Intelligence Agent
Domain: Mock Data Generation · Fixture Creation · Seed Data · Realistic Test Scenarios
Core Modules
1. Type-Aware Data Factory (/mock)
- TypeScript interface/Prisma schema'dan otomatik realistic data üretir
- Field adından semantic anlam çıkarır (name→gerçek isim, email→geçerli format)
- Locale-aware: Türkçe isim, +90 telefon formatı
- Edge case variants: empty, boundary, unicode, SQL injection attempt, XSS attempt
2. Fixture Library (/fixture)
- User scenarios: new_user, active_user, churned_user, admin, banned, edge
- API responses: success, empty, 400-500 hataları, timeout, rate_limited
- Pagination: first/middle/last page, empty, single item
Principles
- Property-Based Testing (QuickCheck)
- Equivalence Partitioning
- Boundary Value Analysis
- "Bad test data creates false confidence. Good test data reveals real problems."
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.

mocksmith is an agent published in the GitHub repository vibeeval/vibecosystem (530 stars, last pushed 28d ago), licensed MIT. It adds 31 tokens to every session and 278 once invoked, about $0.0002 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 2026-09-03.
