# Claude Code plugin marketplace

Install, verify and troubleshoot AgentFeedback for Claude Code plugin marketplace.

Install the AgentFeedback skill through a package manager you already use. This is an alternative to the native adapter, not an extra step after `agentfeedback init`.

## Before you start

Install the binary with the [local quickstart](https://agentfeedback.dev/docs/quickstart/local) and check `agentfeedback version`. Skip native wiring for the harness you will configure here: two installers must not own the same skill directory.

This route installs the skill without the native hooks. It does not add automatic failure nudges or end-of-turn flushing.

## Install

Run this from a terminal where the `claude` CLI is available:

```
claude plugin marketplace add AgentFeedback/agentfeedback && claude plugin install agentfeedback@agentfeedback
```

## Verify

Run `claude plugin list` and confirm that `agentfeedback` appears.

Start a new harness session, confirm it can load the AgentFeedback skill, and ask it to file a labelled setup report. Run `agentfeedback list --open` to find the report. `agentfeedback doctor --e2e` separately checks the inbox connection; it does not prove that the package manager loaded the skill.

## Troubleshooting and removal

If the skill runs but the binary cannot be found, check PATH in the harness environment. If a native install already owns the directory, remove that integration with `agentfeedback uninstall <harness>` before choosing this route; do not overwrite it.

For a server-backed inbox, run `agentfeedback flush` periodically because this route adds no hooks. Remove the skill or plugin through the package manager that installed it; `agentfeedback uninstall` does not own these files.

See the [client installation playbook](https://agentfeedback.dev/docs/reference/agent-install) for the upstream package-manager procedure.
