What it does

Parameter Fuzzing is an agent skill from NeoTheCapt/RedteamAgent. Discover hidden parameters, test values, and identify input handling anomalies

Its SKILL.md is about 940 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 Security, covering Fuzzing 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 Fuzzing
  • Tasks that involve Penetration testing

Example prompts

  • “/parameter-fuzzing”

Workflow steps

9 steps, taken from the step headings in SKILL.md.

  1. Establish Baseline
  2. GET Parameter Discovery
  3. POST Parameter Discovery
  4. Value Fuzzing
  5. Header Fuzzing
  6. Cookie Fuzzing
  7. Multi-Parameter / Clusterbomb
  8. Arjun
  9. Verification

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

Parameter Fuzzing loads about 944 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 164 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~24
When it runs · the whole SKILL.md, loaded when a task matches
~944

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 164 words (~944 tokens).

“run_tool ffuf (primary), run_tool curl (verification), run_tool arjun (dedicated param discovery, if available)”
