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 →

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 C, and why

gitlab-public-recon scanned grade C with 2 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.

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.

GitLab Public Recon Skill

Enumerate publicly accessible GitLab repositories to extract source code, credentials, internal IPs, CI/CD tokens, deployment configurations, and environment files. GitLab instances with registration enabled or public visibility expose the entire development infrastructure. Confirmed on gov-finance-portal (3 public repos, 461K CPFs, internal IP 10.11.82.75, CI/CD tokens), dev-agency (GitLab with SSL private keys), and fitness-chain (Firebase SA keys in repos).

When to Use

  • Target has a gitlab. subdomain or self-hosted GitLab instance.
  • crt.sh reveals gitlab.target.com in certificates.
  • After subdomain-enumeration discovers GitLab hosts.
  • After js-secrets-extraction finds GitLab CI/CD references.
  • Target is a government agency or large enterprise (common self-hosted GitLab users).

Prerequisites

  • terminal with curl, python3, jq.
  • GitLab URL (e.g., https://gitlab.target.com).
  • GitLab API is accessible without authentication for public resources.

How to Run

# List public projects
curl --max-time 30 --connect-timeout 10 -sk "https://gitlab.TARGET.com/api/v4/projects?visibility=public&per_page=100" | jq '.[].path_with_namespace'

# Read a file from a public repo
curl --max-time 30 --connect-timeout 10 -sk "https://gitlab.TARGET.com/api/v4/projects/GROUP%2FPROJECT/repository/files/PATH/raw?ref=main"

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.

gitlab-public-recon is a skill published in the GitHub repository uphiago/recon-skills (1,251 stars, last pushed 8d ago), licensed MIT. It adds 19 tokens to every session and 2,742 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
