What it does
Vulnhunter Run is an agent skill from nealbridges/VulnHunter. Unattended VulnHunter operator. Clone a repo, run the vulnhunt skill with this harness's own tools and subagents, then write and check the scan manifest. Does not call a model SDK and does not name a harness.
Its SKILL.md is about 710 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 Subagents. The repository describes itself as: Agentic AI security scanner that hunts exploitable vulnerabilities like an adversary, proves them with executable PoCs, and fixes them test-first. A maintained fork of Capital… The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Subagents
Example prompts
- “/vulnhunter-run”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Clone. If the user gave a git URL, run vh clone --dest .
- Hunt. Invoke the vulnhunt skill on that checkout. Use this harness's
- Results. Run vh find-results . One directory must be

What it can do on your machine
Read from SKILL.md and the folder at commit b91b81e. 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
Shell commands in SKILL.md call:
python3
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
Vulnhunter Run loads about 711 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 373 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.

- Unattended VulnHunter operator. Clone a repo, run the vulnhunt skill with this harness's own tools and subagents, then write and check the scan manifest. Does not call a model SDK and does not name a harness.
- trigger
- /vulnhunter-run, user asks to scan a repository unattended, user asks to run vulnhunter headlessly
VulnHunter operator
You are the operator, not the hunter. The hunt methodology lives in the
vulnhunt skill. Your harness runs that skill with its own model, tools,
and subagents. You only sequence the steps and refuse to improvise when a
step fails.
Install into the harness that is running you
When asked to install these skills, run install.sh from the repository
root. Do not guess a directory.
- If
GROK_HOMEis set, skills go to$GROK_HOME/skillsand the agent file goes to$GROK_HOME/agents. Do not write to~/.grokwhenGROK_HOMEis a different directory. - Otherwise use the skills directory and the agents directory this harness
scans. Do not use
~/.claude/skillsunless this process is Claude Code. - The same
install.shwritesvhto~/.local/binunlessVULNHUNT_BIN_DIRis set.vhis what later steps call. It is notpython3 -m vhfrom some other checkout.
VULNHUNT_SKILLS_DIR="$GROK_HOME/skills" \
VULNHUNT_AGENTS_DIR="$GROK_HOME/agents" \
./install.shOmit GROK_HOME from that command when it is unset, and pass this harness's
own two directories instead.
The vh commands do not talk to a model.

Steps
- Clone. If the user gave a git URL, run
vh clone <url> --dest <dir>. If they gave a checkout, use that directory and skip the clone. - Hunt. Invoke the
vulnhuntskill on that checkout. Use this harness's subagents for the phase fan-out the skill describes. Do not shell out to another product's agent CLI. Wait until the skill finishes. - Results. Run
vh find-results <checkout>. One directory must be printed. If none is printed, stop and say the hunt produced no results. Do not invent a results directory. - Manifest. Run
vh write-manifest <results-dir>, thenvh validate-manifest <results-dir>. If validation fails, stop and report the error. Do not hand-edit the manifest to force a pass. - Stop. Tell the user the results path and whether the manifest
validated. Publishing and GitHub issue filing are separate; do them only
when the user asked, and use
gitandghdirectly. Do not claim an issue was filed unlessghprinted the URL.
Headless lab use
A batch runner sets VULNHUNT_HOST_CMD to this harness's headless one-shot.
That program receives the prompt file path as its last argument and writes
its transcript to stdout. vh host <prompt-file> is the only launcher.
There is no default command.
