+# Plugin commands
+
+Use these to make, check, load and manage Orca plugins (themes, terminal themes, icon themes,
+syntaxes, language packs, custom editors, panels). All commands take `--json`; branch on
+`error.code`, not on wording.
+
+```text
+ORCA plugin create <dir> --template <theme|terminal-theme|icon-theme|syntax|language-pack|editor|panel> --publisher <owner> [--id <id>] [--name <name>] --json
+ORCA plugin validate <dir|orca-plugin.json|orca-catalog.json> --json
+ORCA plugin inspect <dir> --json
+ORCA plugin dev load <dir> [--approve <fingerprint>] --json
+ORCA plugin dev reload [<dir>] [--approve <fingerprint>] --json
+ORCA plugin dev unload <dir|plugin-key> --json
+ORCA plugin list --json
+ORCA plugin logs <plugin-key> --json
+ORCA plugin enable <plugin-key> [--approve <fingerprint>] --json
+ORCA plugin disable <plugin-key> --json
+```
+
+Exit codes: `0` ok, `1` error, `2` `plugin_invalid`, `3` `approval_required` or `approval_stale`.
+
+## Make and load a plugin
+
+1. `plugin create` into a new folder. Set `--publisher` to the GitHub or GitLab user or
+   organization that will own the repository; `stablyai` and an `orca-` id prefix are reserved.
+2. Edit the files. Field rules: `docs/reference/plugin-manifest.md`, `plugin-themes.md`,
+   `plugin-theme-tokens.md`, `plugin-syntax.md` and `plugin-authoring.md` in the Orca repository.
+3. `plugin validate` until it passes. It is offline and never runs plugin code.
+4. `plugin dev load <dir>` adds the folder to Settings → Plugins → Development folders on the
+   Orca host and loads it. Orca reloads it when its files change; run `plugin dev reload <dir>`
+   if a change was missed. `plugin logs` shows what a panel or worker printed.
+5. `plugin dev unload <dir>` when done.
+
+Paths are on the machine that runs Orca. With `--environment <server>`, pass an absolute path
+on that server. From an SSH or WSL shell that forwards `orca` to another machine, the authoring
+and dev commands refuse; work on the Orca host instead.
+
+`plugin_system_disabled` means plugins are off on that host. Ask the user to click "Turn on
+plugins" in Settings → Plugins; there is no CLI way to turn them on.
+
+## Approval
+
+- Content-only plugins (themes, terminal themes, icon themes, syntaxes, language packs) load
+  and enable without approval.
+- Anything that runs code or acts in Orca (panels, editors, commands, shortcuts, workers,
+  capabilities) fails with `approval_required` (exit 3). `error.message` and `error.data`
+  say exactly what it would be granted, why approval is needed, and `error.data.command`, the
+  same command with `--approve <fingerprint>`.
+- The fingerprint is bound to that plugin, version, files and access. A different plugin,
+  version, set of files, or more access gets `approval_stale` with the new grants and a new
+  fingerprint.
+- Approving grants real access on the user's machine or server. Ask your user before re-running
+  with `--approve` unless they already asked for exactly this plugin and this access. Never pass a
+  fingerprint you did not get from Orca for this exact command. Each approval is written to the
+  plugin audit log as approved via CLI.
+- Without approval a development folder stays loaded but nothing in it runs.
+- For an approved development folder, later code edits run without asking again; new
+  capabilities, a higher execution level, or changed commands and shortcuts need a new approval.
+- `disable` and `dev unload` never need approval.
+
+## Publish
+
+There is no publish command. Use Git and `gh` with the user's own credentials:
+
+1. `plugin validate .` must pass, and the work must be committed and pushed to the GitHub
+   repository whose owner matches `publisher`.
+2. Set `version` in `orca-plugin.json`, commit, then tag that commit `v<version>` and push the
+   tag: `git tag -a v1.2.0 -m v1.2.0 && git push origin v1.2.0`.
+3. Add the `orca-plugin` topic to the repository: `gh repo edit <owner>/<repo> --add-topic orca-plugin`.
+4. Check the listing status at `https://www.onorca.dev/plugins/<owner>/<repo>`.
+
+Publishing is public and acts under the user's GitHub identity; do it only when the user asked
+to publish.
