Purpose: The graph is the third retrieval layer. Authoring it correctly — idempotent extraction, backend-neutral query layer, honest confidence scores — is what makes cos_graph_* tools faster + more accurate than grep. Getting any one of those wrong corrupts the graph silently, and the agent starts trusting hallucinations.
Graph Os Authoring is a community-contributed Claude Code skill in the web-security sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/graph-os-authoring/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when adding a new node/edge type, writing a new extractor (Python AST, doc-headings, etc.), evolving the SQLite backend, or modifying the reindex dispatcher.
The Graph Os Authoring Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 191,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
mkdir -p ~/.claude/skills/graph-os-authoring curl -L https://claudskills.com/skills/graph-os-authoring/SKILL.md \ -o ~/.claude/skills/graph-os-authoring/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/graph-os-authoring/. Claude Code auto-discovers it on next session.
Skills live at ~/.claude/skills/graph-os-authoring/SKILL.md on macOS/Linux, or %USERPROFILE%\.claude\skills\graph-os-authoring\SKILL.md on Windows. See the full install guide for step-by-step instructions.

The ClaudSkills desktop app installs any skill directly into ~/.claude/skills/ with one click — no terminal required. Pro starts at $9/mo or $149 lifetime.
For the full experience including quality scoring and one-click install features for each skill — upgrade to Pro.
SKILL.md from the source repository to ~/.claude/skills/graph-os-authoring/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Graph Os Authoring is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
