* plugins: contributes.hooks runtime with terminal.send and workspace.create hooks
Workers register orca.hooks.on(hook, (event, next) => ...). Orca runs listed
plugins in order before it acts: next(event) continues with allowed fields
changed, { deny } stops, nothing passes. A plugin past its 2 s deadline, or
one that throws, crashes or is disabled, counts as passing and is logged with
plugin, hook and duration. First hooks: terminal.send (runtime sendTerminal),
workspace.create.before (IPC and runtime creates, folders included) and
observe-only workspace.create.after. orca/testing mountWorker gains
hooks.fire. Needs main + trusted-worker and engines.orca >=1.4.248.

* plugins: keep hook plugins' workers started; bound start-up separately from the hook deadline
Workers of enabled plugins that list hooks start as soon as they are approved
and are never idle-reaped; crash restarts follow the manager's policy. A hook
waits up to the worker ready timeout for start-up, then gives the handler its
full 2 s, so a cold worker no longer lets the first hooked action through.

* plugins: give hook workers their own soft cap instead of the active-worker cap
Always-running hook workers no longer hold slots of the shared 5-worker cap, so
many hook plugins cannot starve the rest. They have a soft cap of 16; past it a
hook worker waits for another to stop, logged once.
Co-Authored-By: Claude <noreply@anthropic.com>
* test(plugins): type the hook warmer's ensureWorker mock
* plugins: address hook review: ordering, human input, overflow, revalidation, folder creates
- Hook workers past the soft cap start as overflow (logged once) instead of
waiting, so reconciliation, disable and uninstall never hang.
- Writes to one terminal stay in order while terminal.send decides, so a later
Enter cannot submit the previous line.
- terminal.send runs only for programmatic sends (main, plugins, the CLI);
desktop, mobile and legacy client input is a person's typing.
- Text a hook rewrote passes the AI Vault resume check again.
- Project-group folder workspace creates (RPC, agent launch, window) run the
workspace.create hooks through one boundary.
- A decision from a plugin disabled or changed while it ran is discarded.

* test(plugins): drive hook start-up timing with fake-timer deferreds, no real sleeps
Co-Authored-By: Claude <noreply@anthropic.com>
* plugins: only the hook decision holds a terminal's write order
A delivery that waits (a permission prompt, the launch composer) no longer
blocks later writes, and a person's input, interrupts and query replies never
wait behind a pending decision.
Co-Authored-By: Claude <noreply@anthropic.com>
* plugins: hook DX: onError deny, denied_by_plugin, a Hooks reference, --template hook
- contributes.hooks[].onError: "deny" makes a throw, timeout, crash or bad
answer refuse the action, naming the plugin; the default still passes.
orca/testing mountWorker honours it, and mockHost answers fire-and-forget
methods (result { ok: true }) with success by default.
- A plugin denial reaches RPC clients as denied_by_plugin with the plugin and
reason, and the CLI no longer suggests a retry for it.
- The skill's host-api reference gains a generated Hooks section (event, what
next may change, stop result); the recipe passes sends through unchanged and
warns against awaiting other calls before deciding.
- orca plugin create --template hook: a worker-only terminal.send guard that
fails closed, with a test.

* plugins: regenerate hook docs on main; bind the plugin runtime and its hook runner in one call
Keeps main-process-plugins.ts under 300 lines now that status bar items landed.

Orca plugin catalog reference
The orca-catalog.json file that lists installable plugins and their releases.
Add "$schema": "https://raw.githubusercontent.com/stablyai/orca/main/docs/schemas/plugins/orca-catalog.v2.schema.json" to orca-catalog.json for completion and inline errors in your editor.
Since is the first Orca release that reads the field. Older releases ignore fields they do not know.
Fields
| Field | Type | Required | Since | Description |
|---|---|---|---|---|
$schema |
string | no | 1.4.245 | JSON Schema URL for editor completion. Ignored by Orca. |
catalogVersion |
2 |
yes | 1.4.245 | Catalog format. Raised only for a change older Orca cannot ignore; a newer Orca reads this one. |
name |
string | yes | 1.4.245 | Catalog display name. Example: "Orca Plugins" |
owner |
string | yes | 1.4.245 | Account that publishes the catalog. Example: "stablyai" |
plugins |
CatalogEntry[] | yes | 1.4.245 | Listed plugins, at most 2048. Each id should appear once; Orca keeps the first. An entry this Orca cannot read is skipped, never fatal. |
CatalogEntry
One installable plugin.
| Field | Type | Required | Since | Description |
|---|---|---|---|---|
id |
string | yes | 1.4.245 | <publisher>.<id>: the publisher is the repository owner, lowercased (Orca installs under this key, whatever the manifest's deprecated publisher says), and the id is the manifest's id. Each half is at most 64 characters, and the reserved names constructor and prototype are refused. Example: "acme.gleam-syntax" |
source |
CatalogGitSource | yes | Where the plugin source lives. | |
ownerId |
integer | no | 1.4.246 | GitHub's numeric id of the repository owner, recorded the first time the plugin was listed. Names can be renamed or re-registered; this id cannot. Informational: Orca does not read it yet, and older Orca ignores it. Example: 1234567 |
description |
string | no | 1.4.245 | Listing text shown in the catalog. |
categories |
string[] | no | 1.4.245 | Lowercase slugs used to filter the catalog, each listed once. At most 16; extras are ignored. |
releases |
CatalogRelease[] | yes | 1.4.245 | Installable releases, newest first. Orca installs the first one whose minimumOrca it meets, so keep older releases listed when you raise engines.orca. At most 32. |

path |
string | no | 1.4.245 | Directory inside the repository that holds orca-plugin.json, so one repository can publish many plugins. Use / separators, with no leading /, . or ... Omit when the plugin is the repository root. Example: "plugins/gleam-syntax" |
CatalogRelease
The exact release the catalog vouches for. Orca refuses bytes that differ.
| Field | Type | Required | Since | Description |

("interface-language" | "app-theme" | "terminal-theme" | "icon-theme" | "syntax" | "instructions" | "panel" | "editor" | "worker")[] |
no | 1.4.245 | Optional; Orca derives it from contributes and execution. When present, every kind of contribution the release carries, matching its manifest exactly. instructions needs the declarative profile or higher, panel and editor need sandboxed-ui, and worker needs trusted-worker. Example: ["syntax"] |

Versions and compatibility
- What only lists is tolerant. A catalog never decides what runs (installing re-checks the exact bytes), so Orca keeps whatever it can read: unknown keys are ignored at every level, an entry it cannot read is skipped, an invalid display-only field is dropped, a list over its limit is trimmed, and a repeated
idkeeps the first entry. Validation in CI is where these become errors. - The file name never changes.
catalogVersion(now 2) rises only for a change older clients cannot ignore; an Orca that sees a higher number refuses the catalog with "update Orca to browse this catalog" rather than misreading it. - Releases are a list, newest first. Orca offers the first release whose
minimumOrcait meets, so keep the previous release listed when a new one raisesengines.orca; Orca shows "Needs Orca X" only when none fits.
Publisher names and trust
- Publisher is the repository owner. Like a Go module path, a plugin's publisher is where it lives, never what its manifest says: the official and community catalogs set each entry's
idto<owner>.<manifest id>from the GitHub user or organization that owns the repository (acmeforgithub.com/acme/gleam-syntax), and Orca installs under thatid. A Git URL install uses the URL's owner and a folder useslocal. The manifest'spublisheris deprecated and ignored. Orca does not check the owner for catalogs you add yourself; theiridis what they say. - Listed names are pinned to GitHub ids. The community catalog records the numeric owner and repository ids when a plugin is first listed, pauses new versions after a rename or transfer until Stably confirms it, and refuses a repository that was deleted and recreated under the same name. Each listed version is permanent: a moved tag never replaces it.
- Reserved names install only from Orca's official catalog. The publishers
stablyai,official,anthropic,openai,githuband any startingorca(any case), and ids startingorca-, are refused from any other catalog, a Git URL or a local folder. A catalog that lists one is refused whole.pnpm validate:pluginrejects these publishers exceptstablyai. - Trust comes from the catalog's address. Orca labels a plugin with where it came from: the Official mark for Orca's catalog, otherwise the catalog's name and the owner in its Git URL (
github.com/acme,gitlab.com/acme/tools), never the manifest's text. Development folders showDev · unverified, Git URL installsUnverified. - An install stays with its catalog. Orca records the catalog each plugin was installed from and updates it only from there. When another catalog lists the same id, the plugin page says so, and switching means removing the plugin and installing it again.
One repository can hold many plugins
Give each plugin its own directory and set source.path to it. Orca downloads the pinned commit but installs only that directory, and contentHash covers only its files, so a commit that changes a sibling plugin leaves this plugin's hash, and its users, untouched. Moving a plugin to another directory counts as moving repositories: users review the update before it installs.
{ "id": "acme.gleam-syntax", "source": { "kind": "git", "url": "https://github.com/acme/orca-plugins.git", "ref": "main", "path": "plugins/gleam-syntax" } }
Run pnpm validate:plugin plugins/gleam-syntax in that repository to print the directory's path and its release entry. Listing images stay relative to the catalog repository.
Install links
An install link opens Orca at a plugin's page in Settings → Plugins. It never installs: the user reads the page and presses Install, and the usual review applies. If plugins are off, the page waits behind Turn on plugins.
orca://plugins/<publisher>.<id>?catalog=<official | community | catalog Git URL>
catalogdefaults toofficial.communityis Orca's community catalog. Any other value must be an HTTPS or SSH Git URL of at most 512 characters, read at itsmainbranch, without a password or token. Orca asks Add catalog …? before fetching a catalog the user hasn't added, and that includescommunity.- Reserved publishers (above) are accepted only with the official catalog. A link longer than 2048 characters, with another query parameter, or with an id that isn't
<publisher>.<id>shows a short error and does nothing else. Repeats of the same link within a few seconds are ignored. - Browsers and README viewers often block custom schemes, so link to the directory page instead. It opens the
orca://link and shows install steps when Orca is missing:https://onorca.dev/plugins/<publisher>.<id>?catalog=<same value>.

Clients before format 2
Orca reads orca-catalog.json first and falls back to orca-marketplace.json. That older file is frozen: shipped clients reject any key they do not know, so it carries only name, owner and each plugin's id, source, description and categories, and leaves out plugins with a source.path, which those clients would install from the repository root. Generate it from orca-catalog.json rather than editing two files:
node config/scripts/export-legacy-plugin-catalog.mjs orca-catalog.json orca-marketplace.json
