# codexbar-quota-handoff Development

## Local setup

From the repository root, run the only public setup entry point:

```bash
bash scripts/setup.sh --plugin codexbar-quota-handoff --threshold 0.9
```

In a terminal the script interactively installs the plugin into a selected
Claude Code, Codex, or Copilot runtime, then configures the host integration.
It detects and skips an existing plugin install. Pass `--local` to register
this checkout instead of the published GitHub source, or use `--runtime` and
`--yes` for non-interactive setup. Grok uses only the global hook.

The root `scripts/upgrade.sh` and `scripts/uninstall.sh` use the same interactive
runtime/plugin-state flow. Upgrade refreshes the local integration; uninstall
removes it after the selected plugin-manager entry is removed.
Plugin-local `configure-host.sh` and `remove-host.sh` are internal post-action
helpers and are not public lifecycle entry points.

## Checks

From the repository root:

```bash
for test in tests/codexbar-quota-handoff-*.sh; do bash "$test"; done
mise run lint
```

The three marketplace manifests (`.claude-plugin/`, `.agents/plugins/`,
`.grok-plugin/`) must continue to resolve to this shared plugin root; Copilot
and Cursor reuse the Claude one, so there is no fourth. Grok does not register
marketplace hooks, so its reminder path is the Stop-only global hook
`~/.grok/hooks/codexbar-quota-handoff.json` written by the root setup.

The reminder's host detection depends on each runtime's hook identity variables
and the order they are tested in (`../../docs/agents/harnesses.md`). Reminder
env cases: `CURSOR_INVOKED_AS=cursor-agent` must select
`quota-low-cursor.json`, not `quota-low-claude.json`.

## Prevent Recurrence

- Propose a candidate only when you can name who hits it again, where, and on
  what change.
- On confirmation, offer the first tier that reaches them and only that one:
  enforce it (assert/type/test) with its size quoted, else a comment at that
  site, else the nearest existing topic document with a backtick-path pointer here
  and one sentence on why the tiers above cannot hold it.
- When adding to a file, audit the rest of it in the same pass; drop entries
  once tests or current documentation make them redundant.
