A2X Marketplace

Personal Claude Code plugins — stable utilities for development, planning, knowledge work, and bot operations. Install what you need, when you need it.

Install

/plugin marketplace add thamam/A2X-marketplace
/plugin install <plugin>@A2X

Claude remains the source of truth for its own installation and updates:

/plugin update <plugin>@A2X

For Cursor, Codex, and hosts using .agents/skills, sync the same canonical skills without maintaining separate copies of their source:

python3 scripts/sync_skills.py --target all

This updates ~/.cursor/skills/, ~/.codex/skills/, and

~/.agents/skills/. Claude is intentionally excluded because /plugin owns its lifecycle. Use --target claude only when explicitly managing a separate non-marketplace Claude skill directory. The sync state and hashes prevent unmanaged skills from being overwritten; use --overwrite only after review.

Profiles

profile-manager is always enabled and bundles plugins into workflow profiles so you can switch sets at once instead of toggling individually.

/profile list          # show profiles (dev, planning, research, meta, ops, full, minimal)
/profile dev           # activate a profile
/layout                # open the interactive marketplace layout designer

layout-designer.html at the repo root is the tool /layout opens — you can also open it directly in a browser.
