What it does
Open Redirect Testing is an agent skill from NeoTheCapt/RedteamAgent. Test for unvalidated redirects — URL parameters, login flows, OAuth callbacks that redirect to attacker-controlled domains
Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering Authentication, OAuth and OpenID Connect and Penetration testing. The repository describes itself as: An AI red-team agent for authorized labs and web app pentesting workflows. Turns Claude Code / OpenCode / Codex into a structured recon → test → exploit → report workflow, with…
When your agent uses it
- Tasks that involve Authentication
- Tasks that involve OAuth and OpenID Connect
- Tasks that involve Penetration testing
Example prompts
- “/open-redirect-testing”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Identify Redirect Parameters
- Test Redirect Bypass Techniques
- Test in Authentication Flows
What it can do on your machine
Read from SKILL.md and the folder at commit 2e60476. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Open Redirect Testing loads about 608 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 77 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 77 words (~608 tokens).
