Problem

Installing an extension currently requires `pip install -e extensions/my-extension`, which assumes the agent knows the absolute path, the correct pip binary (`.venv/bin/pip`), and the `-e` flag. This is fragile for autonomous agents working from different directories.

Proposed Solution

```bash

Install an extension by path

pyrite extension install extensions/legal

Install and verify

pyrite extension install extensions/legal --verify

List installed extensions

pyrite extension list

Uninstall

pyrite extension uninstall legal ```

Behavior

Resolves the path to the extension's pyproject.toml

Runs `pip install -e ` using the correct Python environment

With `--verify`: imports the plugin, checks it registers correctly, runs its tests

`pyrite extension list`: shows installed plugins with their registered types, tools, and hooks

`--format json` for all subcommands

extension-init-cli — Creates the extension; this command installs it

bhag-self-configuring-knowledge-infrastructure — Agent self-installation loop
