What it does

Skillward Audit is an agent skill from Fangcun-AI/SkillWard. Security-audit a third-party skill bundle (folder with SKILL.md, or .zip / .tar.gz archive) before installing it, using the SkillWard cloud scanner. Trigger on any natural safety question about an external skill — "is this skill safe?", "audit / scan / review this skill", "should I install this?", "trustworthy?", "any malware?", "is it sketchy?" — even when the user doesn't name SkillWard explicitly. Do NOT trigger when the user is authoring their own skill, asking for a code review of code they wrote, or…

Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/scan.py`).

It sits in Security, covering Security review and Code review. The repository describes itself as: Security scanner for Agent Skills — uncover hidden threats before deployment.

When your agent uses it

  • Any natural safety question about an external skill — is this skill safe?
  • Audit / scan / review this skill
  • Should I install this?
  • Is it sketchy? — even when the user doesnt name SkillWard explicitly

Example prompts

  • “is this skill safe?”
  • “audit / scan / review this skill”
  • “should I install this?”
  • “/skillward-audit”

Requirements

  • Python 3
  • Docker

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. User gave a path — verify it exists. If it's a folder, confirm it contains
  2. User said "this skill" / "the skill" without a path — ask one clarifying
  3. User gave a URL or GitHub link — v1 does not support remote fetching.

What it can do on your machine

Read from SKILL.md and the folder at commit 7e406b7. 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

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • skillward.fangcunleap.com

    Also links to:

    • github.com

    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

Skillward Audit loads about 2.9k tokens when it runs. Until then it costs about 143 tokens; SKILL.md has 1,430 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~143
When it runs · the whole SKILL.md, loaded when a task matches
~2.9k

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); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,430 words (~2,870 tokens).

“Thin client for the SkillWard public scanning service at https://skillward.fangcunleap.com. Given a local skill bundle (folder with SKILL.md, or a .zip / .tar.gz archive), this skill packages it, uploads it to the remote service, streams scan progress, and reports the…”
