Build and deploy Claude Code extensions (skills, hooks, agents, agent teams, ralph loops, graph workflows, slash commands) and answer questions about Claude Code functionality. Use when (1) creating new Claude Code functionality, setting up .claude infrastructure, creating custom hooks (SessionStart, PreToolUse, PermissionRequest, SubagentStart, SubagentStop, PostToolUseFailure, TeammateIdle, Stop), developing specialized agents, implementing skills, coordinating agent teams, setting up Ralph Loops, or designing graph workflows, OR (2) asking questions about Claude Code features, agent teams, hook patterns, skill development, memory system, modular rules, MCP integration, ralph loop, graph workflow, agentic loop, fresh context pattern, .claude directory structure, progressive disclosure, 500-line rule, OR (3) building programmatic LLM systems with Agent SDK. Includes P1 official documentation references and implementation guides.
Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
Claude Skills install to a single target, no runtime picker.
nerlo install -- cathy-kim/ccbuilder
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- cathy-kim/ccbuilder ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
4 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
This review has not run for this scan yet. It runs once per scan, in the background, and is kept; it appears here when it has. Until then all 45 findings above stand exactly as their scanners reported them, at full severity.
