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 | $0.00039 | $0.02737 |
| Opus 5 | $0.00019 | $0.01368 |
| Sonnet 5 | $0.00008 | $0.00547 |
| Haiku 4.5 | $0.00004 | $0.00274 |
Grade A, and why
bypassing-authentication-with-forced-browsing 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 6d 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.

Bypassing Authentication with Forced Browsing
When to Use
- During authorized penetration tests to discover hidden or unprotected administrative pages
- When testing whether authentication is consistently enforced across all application endpoints
- For identifying backup files, configuration files, and debug interfaces left exposed in production
- When assessing access control on API endpoints that should require authentication
- During security audits to validate that all sensitive resources enforce session validation
Prerequisites
- Authorization: Written penetration testing agreement covering directory enumeration
- ffuf: Fast web fuzzer (
go install github.com/ffuf/ffuf/v2@latest) - Gobuster: Directory brute-force tool (
apt install gobuster) - Burp Suite: For intercepting and analyzing requests and responses
- Wordlists: SecLists collection (
git clone https://github.com/danielmiessler/SecLists.git) - Target access: Network connectivity and valid test credentials for authenticated comparison
Workflow
Step 1: Enumerate Hidden Directories and Files
Use ffuf or Gobuster to discover paths not linked in the application's navigation.
# Directory enumeration with ffuf
ffuf -u https://target.example.com/FUZZ \
-w /usr/share/seclists/Discovery/Web-Content/raft-medium-directories.txt \
-mc 200,301,302,403 \
-fc 404 \
-o results-dirs.json -of json \
-t 50 -rate 100
# File enumeration with common extensions
ffuf -u https://target.example.com/FUZZ \
-w /usr/share/seclists/Discovery/Web-Content/raft-medium-files.txt \
-e .php,.asp,.aspx,.jsp,.html,.js,.json,.xml,.bak,.old,.txt,.cfg,.conf,.env \
-mc 200,301,302,403 \
-fc 404 \
-o results-files.json -of json \
-t 50 -rate 100
# Gobuster for directory enumeration
gobuster dir -u https://target.example.com \
-w /usr/share/seclists/Discovery/Web-Content/directory-list-2.3-medium.txt \
-s "200,204,301,302,307,403" \
-x php,asp,aspx,jsp,html \
-o gobuster-results.txt \
-t 50
What ships with it
2 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.

bypassing-authentication-with-forced-browsing is a skill published in the GitHub repository Youngmaidainon/Agent-Level-Up (3 stars, last pushed 15d ago), licensed MIT. It adds 39 tokens to every session and 2,737 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 100% identical to bypassing-authentication-with-forced-browsing, differing in 0 lines, and is treated as a copy.
