SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code scans file system directories looking for sensitive files. This could be reconnaissance for credential theft.
    Fix: Remove unnecessary filesystem scanning. If file access is needed, use explicit, scoped paths. Avoid reading ~/.ssh, ~/.aws, or credential directories.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

skill-installer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/_common.py, scripts/install_skill.py, scripts/list_skills.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Skill Installer

Helps install skills from GitHub or other sources.

Quick Commands

List installed skills:

ls -la ~/.ouro/skills/

Install from GitHub via the /skills menu or /skills call skill-installer:

python scripts/install_skill.py --url https://github.com/owner/repo
python scripts/install_skill.py --url https://github.com/owner/repo#path/to/skill

Installation Sources

From GitHub URL

Install a skill from any public GitHub repository:

python scripts/install_skill.py --url https://github.com/owner/repo

For private repos, ensure git credentials are configured.

From Subdirectory

If the skill is in a subdirectory, use the #path suffix:

python scripts/install_skill.py --url https://github.com/owner/repo#skills/my-skill

From Local Path

Copy a local skill directory:

cp -r /path/to/skill ~/.ouro/skills/skill-name

Listing Skills

List Installed Skills

python scripts/list_skills.py --installed

Or directly:

ls ~/.ouro/skills/

List Available Skills from Registry

python scripts/list_skills.py --repo owner/repo --path skills

Behavior

  • Skills are installed to ~/.ouro/skills/<skill-name>
  • Installation fails if the destination already exists (no overwrite)
  • Git clone uses --depth 1 for efficiency
  • After installation, skills are available immediately (no restart needed)

Notes

  • Private repos require git credentials or GITHUB_TOKEN/GH_TOKEN environment variable
  • Installed skills are loaded on ouro startup
  • Each skill must have a valid SKILL.md with name and description in frontmatter
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
