Stop herding AI skills across Claude, Codex, and Cursor

What it does

skillshare treats your AI tool configurations like a dotfiles repo. You keep skills, agents, and extra rules in one directory—~/.config/skillshare/—and the tool syncs them to the native config paths of Codex, Claude Code, Cursor, and dozens of others. It uses symlinks on Unix and NTFS junctions on Windows, so updates propagate instantly without manual copying.

The interesting bit

The “extras” feature with extension transforms is where it gets clever: it can take a single Markdown source file and convert it to Gemini TOML or Codex TOML agents on the fly during sync, papering over format differences between tools. It also runs a built-in security audit scanning for prompt injection and data exfiltration before anything reaches your agent.

Key highlights

• Single Go binary, no registry or telemetry; runs fully offline after install.
• Supports 60+ targets, with filtering via .skillignore and per-target include/exclude rules.
• Manages skills, custom agents, and extras (rules, commands, prompts) from one Git-tracked source.
• Built-in web UI (skillshare ui) and TUI for visual management and auditing.
• Team workflows via project-local .skillshare/ directories or shared organization repos.

Verdict

Worth a look if you juggle multiple AI coding assistants or need to standardize prompts across a team. Skip it if you live inside a single tool and never leave.
