github-org-security-overview

github-org-security-overview is a skill for Claude Code, Codex from mappedsky/seizu. It costs 29 tokens per session (730 once invoked), scanned A, original, Apache-2.0.

A guide for reviewing the security of a GitHub organization, which is a group of repositories managed together.

In plain words
What is it for?
Checking repository exposure, open security alerts, high-risk projects, and the most urgent vulnerabilities.
Why use it?
It structures the investigation so important repositories, vulnerabilities, and stale data are not missed.

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

github-org-security-overview 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 4d 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.

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

Investigate the GitHub organization org using the github_security user-defined tools. Treat org as an explicit required input and do not substitute a default organization.

Inputs — the values arrive in the ## Inputs block below these instructions:

  • org — the organization to review; empty matches every organization in the graph.
  • exclude_forks — whether forked repositories are left out.
  • include_archived — whether archived repositories are included.
  • limit — how many rows to request from each ranked query.

Workflow:

  1. Call github_security__sync_freshness with org first. State the newest GitHub sync timestamp and qualify the report if the data looks stale or incomplete.
  2. Call github_security__org_overview with org, exclude_forks, and include_archived. Establish repository count, visibility split, alert totals, and any caveats around fork metadata.
  3. Call github_security__repo_risk_summary and identify the highest-risk repositories by critical/high alerts, total open alerts, public exposure, and risk score.
  4. Call github_security__top_vulnerabilities with state='open' and limit. Prioritize critical and high findings, then high EPSS/CVSS medium findings if they materially change remediation order.
  5. Call github_security__actions_hardening_findings. Look for unpinned actions, write-level permissions, publish/deploy workflows, and pull_request_target usage.
  6. Call github_security__coverage_gaps. Identify missing CodeQL, Scorecard, dependency graph coverage, manifests, and language metadata.
  7. Call github_security__identity_access_summary. Summarize org admins, direct repo admins, and MFA visibility limits without overstating unknown fields.
  8. Call github_security__recommendations and reconcile its computed recommendations with the evidence from the earlier tools.

Output format:

  • Start with a concise security posture summary for org.
  • Include a Data Freshness note with exact sync timestamps when available.
  • Include Top Risks ordered by severity and likely exploitability.
  • Include Vulnerabilities with repository, package, severity, CVE/GHSA when present, patch version, and why it matters.
  • Include Misconfigurations and Coverage Gaps focused on GitHub Actions, scanning, dependency visibility, and identity/access findings.
  • Include Top Recommendations as a numbered remediation plan, with affected repositories and concrete next actions.
  • Call out graph limitations explicitly, especially missing fork metadata, archived state uncertainty, absent MFA fields, or repositories with no dependency manifests.
  • Do not claim a repository is forked, archived, protected, or MFA-enforced unless the tool output contains that evidence.
  • Keep the response evidence-backed; separate confirmed facts from inferences.

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.
