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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00052 | $0.01173 |
| Opus 5 | $0.00026 | $0.00587 |
| Sonnet 5 | $0.00010 | $0.00235 |
| Haiku 4.5 | $0.00005 | $0.00117 |
Grade C, and why
Hash Cracking Workflow scanned grade C with 2 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.
Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

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

Hash Cracking Workflow
Step 1: Identify Hash Type
By Length
| Length | Possible Types |
|---|---|
| 32 | MD5, NTLM |
| 40 | SHA1 |
| 56 | SHA224 |
| 64 | SHA256 |
| 96 | SHA384 |
| 128 | SHA512 |
By Format
| Format | Type | Hashcat Mode |
|---|---|---|
$1$salt$hash |
md5crypt | 500 |
$5$salt$hash |
sha256crypt | 7400 |
$6$salt$hash |
sha512crypt | 1800 |
$2a$, $2b$, $2y$ |
bcrypt | 3200 |
$apr1$ |
Apache MD5 | 1600 |
$P$ or $H$ |
phpass (WordPress) | 400 |
Tools
# hashid
hashid '<HASH>'
hashid -m '<HASH>' # Show hashcat mode
# hash-identifier

# haiti (more accurate)
haiti '<HASH>'
Step 2: Find Wordlist
Common Locations
# Kali/Parrot
ls /usr/share/wordlists/rockyou.txt 2>/dev/null
zcat /usr/share/wordlists/rockyou.txt.gz > /tmp/rockyou.txt 2>/dev/null
# SecLists
ls /usr/share/seclists/Passwords/
# Custom locations
ls ~/wordlists/ /opt/wordlists/ 2>/dev/null
Wordlist Priority
rockyou.txt- 14M passwords, good coveragetop-passwords-shortlist.txt- Quick check- Custom company/target wordlist
- Rule-based mutations
Step 3: Crack with Hashcat
Common Modes
# MD5
hashcat -m 0 hash.txt /path/to/rockyou.txt
# NTLM (Windows)
hashcat -m 1000 hash.txt /path/to/rockyou.txt
# SHA1
hashcat -m 100 hash.txt /path/to/rockyou.txt
# SHA256
hashcat -m 1400 hash.txt /path/to/rockyou.txt
# sha512crypt ($6$)
hashcat -m 1800 hash.txt /path/to/rockyou.txt
# bcrypt
hashcat -m 3200 hash.txt /path/to/rockyou.txt
# Kerberoast
hashcat -m 13100 hash.txt /path/to/rockyou.txt
# AS-REP Roast
hashcat -m 18200 hash.txt /path/to/rockyou.txt
With Rules (Better Coverage)
hashcat -m <MODE> hash.txt wordlist.txt -r /usr/share/hashcat/rules/best64.rule
Check Cracked
hashcat -m <MODE> hash.txt --show
Step 4: Alternative - John the Ripper
# Auto-detect format
john hash.txt --wordlist=/path/to/rockyou.txt
# Specific format
john --format=raw-md5 hash.txt --wordlist=/path/to/rockyou.txt
john --format=nt hash.txt --wordlist=/path/to/rockyou.txt
# Show cracked
john hash.txt --show
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.

Hash Cracking Workflow is a skill published in the GitHub repository allsmog/blackbox-claude-plugin (5 stars, last pushed 6mo ago), licensed MIT. It adds 52 tokens to every session and 1,173 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (reaches for credential files, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
