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 | $0.00068 | $0.01356 |
| Opus 5 | $0.00034 | $0.00678 |
| Sonnet 5 | $0.00014 | $0.00271 |
| Haiku 4.5 | $0.00007 | $0.00136 |
Grade A, and why
verfi scanned grade A with 1 finding 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Verfi — Consent Verification for Lead Gen
Verfi captures verifiable proof of consumer consent. Publishers add a script tag to capture sessions; buyers verify consent via API before contacting leads.
When to Use This Skill
- Adding consent capture to a web form
- Checking if a lead has valid TCPA consent
- Claiming sessions for long-term retention
- Pulling machine-readable proof for disputes
- Integrating Verfi into an existing lead gen pipeline
Quick Start
1. Capture Consent (Publisher)
Add the SDK to any page with a form:
<script src="https://sdk.verfi.io/v1/verfi.js" data-key="pk_YOUR_PUBLIC_KEY" async></script>
The SDK auto-detects forms, records interactions (mouse, clicks, keystrokes, scroll), and generates a Verfi ID (VF-xxxxxxxx) on form submission.
2. Verify Consent (Buyer)
curl -H "Authorization: Bearer sk_YOUR_SECRET_KEY" \
https://api.verfi.io/tenant/v1/sessions/VF-a1b2c3d4/proof
Returns consent status, interaction metrics, form data, device info, and tamper verification. All PII is SHA-256 hashed.
3. Claim Session
curl -X POST -H "Authorization: Bearer sk_YOUR_SECRET_KEY" \
https://api.verfi.io/tenant/v1/sessions/VF-a1b2c3d4/claim
Starts 3-year retention. Unclaimed sessions expire in 72 hours.
Authentication
Two key types:
| Key | Format | Use |
|---|---|---|
| Public | pk_... |
SDK script tag (client-side) |
| Secret | sk_... |
API calls (server-side, Bearer token) |
Secret keys have scopes: sessions:claim, sessions:unclaim, sessions:search, sessions:proof, sessions:expiration.
Generate keys in the Verfi dashboard under Integration > API Keys.
API Endpoints
Base URL: https://api.verfi.io/tenant/v1
All endpoints require Authorization: Bearer sk_... header.
| Method | Path | Scope | Description |
|---|---|---|---|
| GET | /sessions |
— | List claimed sessions (paginated) |
| GET | /sessions/{verfiID} |
sessions:search |
Look up session, verify PII hashes |
| GET | /sessions/{verfiID}/proof |
sessions:proof |
Machine-readable proof data |
| POST | /sessions/{verfiID}/claim |
sessions:claim |
Claim session (3-year retention) |
| POST | /sessions/{verfiID}/unclaim |
sessions:unclaim |
Release session (30-day retention) |
| PUT | /sessions/{verfiID}/expiration |
sessions:expiration |
Update expiration date |
What ships with it
3 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.

verfi is a skill published in the GitHub repository Verfi-io/verfi-mcp-server (0 stars, last pushed 10d ago), licensed MIT. It adds 68 tokens to every session and 1,356 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
