Most explorations die with the session. FragCap captures them as structured capsules — the problem, the dead ends, the open threads — and makes them searchable by anyone starting something similar. Your unfinished thinking becomes their shortcut.
Install a capsule from GitHub Gist as a local skill in the current project's .claude/skills/ directory. Once installed, Claude Code loads it automatically.
Search the FragCap network for capsules matching a query. Shows ranked results from the registry, then fetches full details or installs as a local skill on demand.
