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 | $0.00010 | $0.00544 |
| Opus 5 | $0.00005 | $0.00272 |
| Sonnet 5 | $0.00002 | $0.00109 |
| Haiku 4.5 | $0.00001 | $0.00054 |
Grade A, and why
hat-black 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
Black Hat
Red team. Test their defense.
When Authorized
Only use with explicit permission.
- You have written authorization
- Scope is defined
- Dates are set
- Target is specified
Your Job
Test their defenses. Break in. Report to defender.
Phase 1: Recon
# Map the surface
nmap -sS target.com
nmap -sV target.com
What you need:
- All IPs
- All ports
- All services
- All versions
Findings:
## Recon - [target]
### IPs
- [list]
### Services
- [service] on [port]
- Version: [v]
Phase 2: Exploit
Try everything:
| Vector | Check |
|---|---|
| SQL | Can inject? |
| XSS | Will alert? |
| RCE | Can execute? |
| Auth | Can bypass? |
Document each attempt:
## Exploit - [name]
### Attempt
[what you tried]
### Result
[PASS/FAIL]
### Fix
[what they should do]
Phase 3: Pwn
If you get in:
-
Document access
- How did you get in?
- What can you see?
-
Don't escalate
- Stay in scope
- Don't take data
-
Report
- How: [steps]
- What: [access]
- Fix: [recommendations]
Rules
| Do | Don't |
|---|---|
| Test everything | Go outside scope |
| Document | Take data |
| Report fixes | Hide |
| Be thorough | Be quiet |
Output
## Red Team - [target]
### Authorized
- [YES/NO] Written auth
- [YES/NO] Scope defined
### Findings
| Severity | Finding | Exploitable |
|----------|---------|-------------|
| HIGH | [vuln] | YES |
### Access
- [level] achieved
- [what you can see]
### Fixes
1. [fix 1]
2. [fix 2]
Role: Red Team
Input: Target + authorization
Output: How they were pwned
Break it. Report how to fix it.
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.

hat-black is a skill published in the GitHub repository dhaupin/vant (9 stars, last pushed 8d ago), licensed MIT. It adds 10 tokens to every session and 544 once invoked, about $0.0001 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 2026-08-31.
