A mod manager for Claude Code. Mods are plugins that hook into a Claude Code session: they can run programs, read the conversation, change what the model sees. modmgr shows which ones you have and what each one can do, and lets you find, install, switch off, update or remove them without leaving the session.
/plugin install modmgr --marketplace ayagmar/claude-modsThen type /mods. Needs Claude Code 2.1.292 or newer, with the claude CLI on your path.
Installed lists every mod with its state, version, scope and what it can do. Changes are staged and applied together, with one plugin reload after, and the last batch can be undone.

z: undo j: jobs h: keys esc closeA mod's detail says what it hooks and calls, grouped by what that reaches (your machine, the network, the conversation, the model's input, other plugins), and calls out what's worth a second look. When an update adds something notable, it says so until you have seen it:

j: jobs h: keys esc backDiscover lists the mods in every marketplace you have added, and the mods published anywhere else on public GitHub (about 3,000). Both come from indexes modmgr's CI rebuilds daily, so they are there at once; anything else is checked while you work, search matches first. A community mod shows what it can do before you install it, as claude plugin validate read it. Installing goes through a review that says what will run and where: a community mod installs from the marketplace in its own repository, which the install adds to your user settings first, and one whose repository has no marketplace offers its link instead. o sorts by popularity, stars, name or source; k keeps only your own marketplaces' entries. A command a marketplace declares is shown whole, with its sha256, and runs only when you confirm that exact command.

esc backDev lists the mods you are writing (loaded with --plugin-dir, CLAUDE_CODE_PLUGIN_DIRS, your skills folder or a folder marketplace): validate them, run their tests, reload, and get the line someone else needs to install yours.
Health lists what needs you, worst first, each with a fix one key away:

l: reload j: jobs h: keys esc closeUpdates are checked every few hours while no turn is running (updateCheckHours, 0 turns them off).
For scripts and claude -p:
/mods list | info <id> | doctor [--json] | export
/mods install <id> [--scope user|project|local] [--accept-command <sha256>] --yes
/mods remove <id> [--wipe-data] --yes
/mods update [<id>] --yes
/mods enable <id> --yes | disable <id> --yes
/mods apply <file> --yesWrites need --yes (without it they print what they would run) and never reload: run /reload-plugins after. Exit codes: 0 done, 1 refused or failed, 2 usage. Under -p, Claude Code prefixes the answer with modmgr: .
Set them with claude plugin configure modmgr:
| Option | Default | |
|---|---|---|
updateCheckHours | 6 | Hours between update checks; 0 turns them off. |
detectRemote | on | Read the daily catalogue and community indexes, and catalogue entries' hooks.json, from raw.githubusercontent.com to find mods. |
debugTimings | off | Write how long each step took to the debug log (--debug). |
CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC turns off everything modmgr fetches. modmgr sends no telemetry.
modmgr is a lens, not a sandbox: once a mod runs, it runs with your session's power. It tells you what a mod can do and asks before anything new runs. docs/SECURITY.md says what it reads, fetches and stores.
See CONTRIBUTING.md and docs/PERF.md. The landing page is in site/ (pnpm site).
The community index finds mods the way awesome-claude-code-mods (browse it at mods.aidojo.si) does, and reads its list of candidate repositories (CC0) so a mod GitHub's search hasn't indexed yet is still found.
