plugin

Manage complete native plugins across supported tools. Capability checks distinguish installation support from format discovery. Start with Manage plugins across tools.

skillshare plugin                         # Interactive manager
skillshare plugin add                     # Source → plugin → targets → review
skillshare plugin discover ./my-plugin --json
skillshare plugin add ./my-plugin --target claude --target codex --no-tui
skillshare plugin add ./my-plugin --no-tui   # Keep it in Skillshare; choose targets later
skillshare plugin import review@team --from claude --no-tui
skillshare plugin list --json
skillshare plugin inspect review --json
skillshare plugin disable review --target codex --no-tui
skillshare sync plugins --dry-run --json
skillshare sync plugins --no-tui
skillshare plugin enable review --target codex --no-tui
skillshare plugin check review --json
skillshare plugin update review --target claude --no-tui
skillshare plugin remove review --no-tui

enable and disable change Skillshare's sync selection, not the Agent's native enabled state. Deselecting a target saves the choice. The next sync plugins removes its managed installation while retaining the definition. Selecting it again allows the next sync to reinstall it. Unmanaged plugins are unaffected.

add without --target (or with nothing selected in the interactive picker) keeps the plugin in Skillshare without installing it anywhere. Add targets later with the same source and --name, or from the plugin's row in the dashboard; that install uses the source as it is then. Such a plugin stays managed when its last target is removed. remove NAME without --target removes it from Skillshare.

Commands

Command	Behavior
`list`	Configured bindings and native installation state; interactive manager in a terminal
`discover SOURCE`	Inspect a local directory, `owner/repo`, or HTTPS Git repository
`add [SOURCE]`	Choose and install a whole plugin with its target adapter, or an `npm:` package through Pi
`import [NATIVE-ID]`	Adopt an existing installation without reinstalling or enabling it
`inspect NAME`	Inspect one managed package
`sync [NAME]`	Reconcile selected targets and retry incomplete native operations
`check [NAME]`	Compare source content with the recorded digest, or a Pi npm package's version with npm's latest; never update
`update [NAME]`	Review source changes and use a supported native update operation
`enable / disable [NAME]`	Include/exclude a target in the next sync
`remove [NAME]`	Uninstall managed bindings and remove their definitions

Bare commands prompt for missing inputs in a terminal. Noninteractive mutation commands require explicit inputs. sync and check may operate on all packages. sync --all does not include plugins; use sync plugins explicitly.

Options

Option	Meaning
`--target TARGET`	Repeatable selection: `claude`, `codex`, `cursor`, `antigravity` (`agy` alias), `antigravity-cli`, `copilot`, `grok`, `pi`, `omp`, `opencode`, or the name of another account of an Agent; see the capability table below
`--plugin NAME`	Select one plugin from a source marketplace
`--name NAME`	Logical package name when adding or importing
`--from TARGET`	Import from Claude, Codex, Antigravity CLI, Copilot, Grok, Pi, OMP marketplaces, OpenCode, or another account of an Agent
`--dry-run`, `-n`	Preview without changing Skillshare or Agent configuration
`--source-ref REF`	Git branch, tag, or commit for `discover`, `add`, and `update`; remote sources only
`--entry PATH`	Explicit built OpenCode JS/TS entry, relative to the package root (`discover` and `add`)
`--revision ID`	Refuse application if source, configuration, or native inventory changed since preview
`--json`	Machine-readable output; disables TUI
`--no-tui`	Disable interactive menus; also respects `tui: false`
`--global`, `-g`	Global Skillshare config and native user scope
`--project`, `-p`	Project config; Claude, Antigravity, Pi, OMP, or OpenCode (never global fallback)

JSON output includes source paths and native identifiers. Do not put credentials in source URLs. A failed mutation can still return successful per-target outcomes; the CLI exits nonzero when any target fails. Inspect the result before retrying.

Target support

Target	Format	Global	Project	Update
Claude Code	`.claude-plugin/plugin.json`	Yes	Yes	Native update
Codex	`.codex-plugin/plugin.json` or Agent Plugins root manifest	Yes	No	Refresh reviewed source and add it again, only if enabled in Codex
Cursor	`.cursor-plugin/plugin.json` or Agent Plugins root manifest	Yes	No	Replace reviewed local copy
Antigravity Desktop	Root `plugin.json` with an explicit name	Yes	Yes	Replace reviewed local copy
Pi	`package.json` with `pi` resources, or `pi-package` keyword and conventional resource folders	Yes	Yes, with native project trust	Refresh managed source snapshot
Oh My Pi	Marketplace-backed local/Git plugins with native-compatible metadata	Fresh-cache install/reinstall, import and scoped removal	At OMP's project anchor	Updates blocked; removal retains shared cache
OpenCode	`package.json` with an SDK dependency, `.opencode/plugins/` entry, or explicit `--entry`	Yes	Yes	Refresh managed source snapshot

Kimi's noninteractive lifecycle, Hermes's profile inventory/consent, and Devin's local inventory/trust/cloud distinction are not yet verified by these adapters. Their formats are shown during discovery, but installation is disabled with a reason. A source declaring a target does not imply that Skillshare can manage it. list --json and discover --json include targetDefinitions with allowed operations; discovery also exposes targetInfo for each format's version, components, entry, and validation problem. A broken manifest is isolated to its target; a malformed catalog is reported as a warning without hiding valid formats.

Another account of an Agent

A target declared as another account of an Agent is a plugin target too, for claude, codex and pi. Skillshare runs that Agent's own CLI against the account's config directory, through CLAUDE_CONFIG_DIR, CODEX_HOME or PI_CODING_AGENT_DIR:

targets:
  claude-work:
    agent: claude
    config_dir: ~/.claude-work

skillshare plugin add owner/repo --target claude-work
skillshare plugin import demo@market --from claude-work

An account with cli runs that compatible CLI instead, such as omo for a Pi account, against the same config directory. A Pi account also sets SENPI_CODING_AGENT_DIR and OMO_CODING_AGENT_DIR, which Pi forks read before PI_CODING_AGENT_DIR. If the CLI cannot be found, the operation fails; Skillshare does not fall back to the Agent's own.

The account takes the operations of the Agent it belongs to and keeps its own bindings under its own name, so a plugin can be installed in one account and not in the other. Accounts exist in global scope only: a project's plugins belong to the project, not to one account. --target and --from accept the account name, and the terminal picker and the dashboard's Plugins page list it next to the Agents.

Cursor and Antigravity

These adapters copy the whole plugin into documented local discovery directories. They do not require a CLI executable or modify marketplace registries:

Cursor: ~/.cursor/plugins/local/<name>; local imports must be allowed. Reload Cursor and check Customize. An installed marketplace plugin with the same name takes precedence over a local copy.
Antigravity desktop: ~/.gemini/config/plugins/<name> globally; .agents/plugins/<name> in a workspace (or an existing _agents/plugins/ directory). If both workspace directories exist, consolidate them first.
The standalone agy CLI has a separate plugin store. The antigravity target manages the desktop/workspace discovery paths, not that CLI store. agy is only a Skillshare target alias. Use --target antigravity-cli for the standalone CLI; --target agy retains its existing desktop meaning.

Use plugin add for these local packages. Importing pre-existing local folders or marketplace installs is not supported. Skillshare refuses to overwrite unowned folders, symlinks, or locally edited managed content. An explicit Antigravity manifest name keeps the identity stable across Git checkouts and snapshots.

Oh My Pi (OMP)

OMP uses its own marketplace lifecycle, not Pi's package commands. Skillshare manages reviewed local/Git plugin sources and imports native marketplace entries identified as name@marketplace:

skillshare plugin add ./my-omp-plugin --target omp --dry-run --json -g
skillshare plugin add ./my-omp-plugin --target omp --no-tui -g
skillshare plugin import demo@my-market --from omp --dry-run --json -g

Installation requires OMP 18.6.1, a reviewed local/Git source and a verified, previously unused cache destination and an absent scope-local runtime destination. The runtime package name comes from the reviewed source, not just the marketplace name. Existing module directories or links block installation rather than being replaced; the destination is bound to the preview and checked again before install. The adapter keeps the plugin tree together, uses native marketplace installation, and verifies the resulting registration. Catalogs can use .omp-plugin/marketplace.json or the legacy .claude-plugin/marketplace.json. Preview does not invoke OMP's native --dry-run, which can write files. Review the source before applying: OMP can execute plugin extensions and tools in-process at the next startup, without a project trust prompt. Installation is not proof that those resources loaded successfully.

Shared-cache limitation in OMP 18.6.1: its native uninstall and upgrade can delete or replace plugin cache files still referenced by a different project. Native inventory lists only the user registry and the current project's registry, so it cannot establish the safety of those operations across other projects. Skillshare does not invoke those destructive commands. Remove and disable-plus-sync instead use a scoped adapter that deletes the installation's registry entry, runtime selection and verified node_modules link. The plugin is uninstalled from that scope, not merely disabled. Shared cache, marketplaces and plugin settings are retained; no cache garbage collection is attempted. Reinstall automatically chooses a fresh marketplace/cache identity when the old cache still exists, without replacing files another project may use. Unreadable, linked or non-directory cache destinations remain blocked.

Removal requires the verified 18.6.1 metadata contract, matching installed version, unambiguous JSON and proven runtime-link ownership. A real module folder, foreign link, npm dependency collision or ambiguous runtime owner is refused. If the cache manifest is missing, the adapter requires a unique runtime-lock key whose scope-local link points to that installation's cache; it never guesses the marketplace name and reports success with the actual runtime link still installed. Unverifiable active installations remain blocked. If native uninstall already removed the cache, registration and runtime link/selection, Forget drops only the stale Skillshare binding; another plugin's node_modules directory does not block it. Native file changes invalidate the preview. Partially completed removal can be retried from the retained cache and binding identity without saving full native settings backups. Windows writes additionally require verifiable private ACLs; Skillshare does not change permissions to make them pass. No extension code runs.

The adapter serializes Skillshare removals and checks native file revisions, but OMP's plugin commands do not participate in its lock; do not run native plugin mutations concurrently. This is not an atomic multi-file native transaction. Updates remain blocked until a non-destructive upgrade contract is available; imported code is never upgraded without a reviewed source.

Project operations require the selected root to match OMP's native project anchor; they never silently install globally or in an ancestor project. Native profile/config-root overrides (PI_CONFIG_DIR, PI_CODING_AGENT_DIR, OMP_PROFILE or PI_PROFILE) block plugin management. A relocated native cache invalidates an existing preview. An arbitrary account config_dir does not redirect OMP's plugin store, so OMP account plugin targets are not supported.

Native npm/Git/link packages are visible in inventory but are not imported as marketplace plugins. Manage those packages in OMP; plugin add npm:... remains a Pi-only workflow. Do not separately copy a plugin's extensions, hooks, skills or MCP entries into Skillshare's other resources.

Choosing standalone OMP extensions

Open an OMP target's Extensions tab to review file-based selection. Cards group files by source and scope, with plugins grouped by their inspected package root and other files by directory. File lists remain visible. Plugin cards use a package icon and Plugins · <name> heading from the native package identity, not the extension folder name. Known manifest versions and scope stay visible, with an Open Plugins navigation icon rather than repeated origin tags. Shared folders are plugin-relative, and full file paths remain in tooltips. Details uses the same labeled two-column layout as Pi for the full source, native name, selection identifiers and notes. Missing identity metadata falls back to the inspected folder; no package identity or version is guessed. Read-only reasons and links to Hooks or Plugins remain visible with their entries. Supported standalone modules have switches; Preview shows the change and Apply writes only disabledExtensions in the selected native YAML settings file. Global, project and explicitly configured account directories remain separate. The editor preserves unrelated YAML and comments, checks the reviewed revision again under OMP's native lock, and refuses stale or busy writes.

Selection editing requires a verifiable OMP 18.6.1 package behind the selected launcher. Unidentified versions, standalone binaries and wrapper launchers stay read-only. This check reads package metadata without running OMP. Same-name module groups, explicit files that bypass the disabled-name filter, ambient hooks/pre|post factories, uncertain selection and linked paths are read-only. Hooks-owned and plugin-owned entries stay with their respective managers.

The backup records the before/after selection and settings hashes under omp-extensions/backups in Skillshare's state directory, not unrelated YAML values or credentials. It is a selection recovery record, not a whole-settings restore. A successful apply describes configuration on disk, not a running extension; restart/reload remains an OMP action.

Pi and OpenCode

Pi keeps the first global registration and the last project registration of a package. If an earlier global or later project source has an unresolved identity, Skillshare cannot prove which entry owns a package and keeps potentially shadowed entries Unknown/read-only, including inherited project deltas. It does not guess identity by stripping URL queries. Proven entries outside that ambiguity remain editable.

Pi uses pi install / pi remove; inventory reads documented package settings without loading extension code. PI_CODING_AGENT_DIR is respected. Pi project trust must be established in Pi; Skillshare does not pass --approve for you.

npm packages from pi.dev

plugin add npm:<package> installs a package published to npm, such as one listed on pi.dev, through Pi itself:

skillshare plugin add npm:@scope/package --target pi --dry-run --json -g
skillshare plugin add npm:@scope/package@1.2.0 --target pi --no-tui -g

Pi downloads the package and runs its install scripts, so Skillshare can't review its content first; check the package on pi.dev or npm before adding it. discover does not accept npm sources, and an npm source takes no --source-ref, --entry or --plugin. Only Pi targets take npm sources, including a Pi account that runs pi. For an account that runs another executable, install the package with that executable, then import it. With --project, Pi installs the package into the project's settings; once the project has a .pi folder, Pi changes its packages only after you trust the project in Pi.

Pi keeps one entry per package name. If Pi already has the same source, add imports it; another version of the package is installed, and Pi replaces that entry's source. update runs pi update, except for a package pinned to an exact version, which Pi keeps: add the package again with the new version instead. For a package added without a version, check compares the version in the installed package's package.json with the version npm's latest tag names on the public registry, and update leaves a package that is already at that version alone. A package added with a version range or tag, one that the environment or an .npmrc sends to another registry, or one whose version is not a plain X.Y.Z, is reported as something to check in Pi. The dashboard shows the installed version of every Pi package, on the Plugins page and in a Pi target's Extensions tab. When you turned off some of the package's extensions, Pi keeps those rules on the new version, and Skillshare records them again so a later reinstall restores them. A Pi package that another Skillshare package already manages is refused; update or remove that one instead.

In the dashboard's add dialog, you can paste the pi install npm:<package> command or the package's pi.dev address; either becomes its npm: source.

Choosing a package's extensions

In the dashboard, the target page of pi and of a Pi account has an Extensions tab. It lists each package entry of that target's settings.json with the extensions its filters select. Packages managed by Skillshare use a package icon and Plugins · <name> heading, matching OMP plugin cards. They retain the installed version, scope and relevant project override shape; the navigation icon opens Plugins. Unmanaged Pi packages keep their native identity and Pi icon. This presentation does not change ownership or extension-selection rules. Extension rows remain visible; Details independently shows the source and filter rules. A switch writes one exact +path or -path rule into that entry's extensions list. When removing the file's own exact rule already gives the state the switch asks for, the switch removes that rule instead, so turning a file back to what the remaining rules select leaves no rule behind. Remove rule, shown when the switch would not remove the rule itself, deletes the exact rule for that file, written as a relative or an absolute path, and the file then follows the remaining rules; the preview shows the result. Apply shows a preview first and edits only those lists: the entry's other keys, its skills, prompts and themes filters, glob and ! rules, and the rest of the file stay exactly as written. A string entry becomes {"source": ...} so it can hold a rule. For a string entry, Pi takes a package's skills, prompts and themes only from its pi manifest, while an object entry also loads them from the package's skills, prompts and themes folders when the manifest leaves them out. A string entry of a package with such a folder is read-only, because Skillshare can't show that converting it leaves those resources as they are. A source that is one file is read-only too, because Pi loads it as it is and ignores filters. A user-scoped npm registration without a managed cache is Unknown/read-only, not necessarily uninstalled: Pi may use a legacy global npm/pnpm root that Skillshare does not probe. If the file changed after the preview, or Pi holds its settings lock, nothing is written. An empty lock directory older than Pi's 10-second stale threshold can be reclaimed only if its inode and mtime are unchanged. Fresh, renewed, replaced, nonempty, file, and symlink locks are refused. Reclamation follows Pi's stale-lock protocol; age does not prove an owner has died, and the final check/removal is not an atomic CAS. While writing, Skillshare holds that lock the way Pi does and writes nothing if it loses it. Before each apply, Skillshare saves a persistent record of the changed extension lists and the before/after file hashes. Successful records are kept without automatic pruning; if Apply fails, only the new record for that attempt is removed. This is not a copy of settings.json and cannot restore the whole file. The tab lists every package in the settings, including ones installed with Pi itself, such as npm: packages from pi.dev. Skillshare installs and removes packages only through plugin: plugin add takes a local directory, a Git source or an npm package, and plugin import --from pi adopts a package installed with Pi.

Skillshare reads packages without running them, so the tab shows what the settings select (switches and selection notes), not whether Pi loaded them; reload Pi after applying. A file the settings name but the package lacks is marked as missing. A choice Skillshare can't work out shows Can't tell with the reason and where to change it, never a guessed on or off. Editing needs the target's own Pi to be 0.99.2 or later (the oldest version checked against Pi itself) and strict JSON settings; an older version is read-only and the tab says which version it found. A Pi account that runs a different executable is read-only, and Skillshare does not run it. An entry whose list is [] (nothing loads) is read-only, as is any extension decided by a pattern Skillshare cannot evaluate, such as ? against an emoji. An entry with an empty source, or whose source or rules contain an unpaired UTF-16 surrogate escape or invalid UTF-8, is left as written and read-only, since Skillshare can't read it exactly as Pi does. Pi uses only the first global entry of a package, so when Skillshare can't read that entry, the package's later entries are read-only too.

A project that syncs to Pi has the same tab on its project page. It shows each package as the project's settings select it on top of the global ones, marked as inherited from pi (global) or as a project override. A switch saves a rule to the project's .pi/settings.json only, the way pi config does: a global package gets a project entry {"source": ..., "autoload": false, "extensions": [...]} that changes only the files it names and leaves the global entry as it is. A local source is written relative to .pi, an npm or git source as the global settings have it. When the last project rule of such an entry is removed, the entry is removed only if that cannot reveal an earlier registration's filters; otherwise the empty winning override is kept. Only explicit JSON false means a delta; autoload: null is not false. A project entry with autoload: false and no global entry loads only the files it names with +. The file, and its .pi folder, are created only when you apply. The global settings and Pi's trust.json are never written, and Skillshare never trusts a project for you: Pi uses the project's settings only if it trusts the project. A global source that carries credentials or a query is never copied into a project, so that package is read-only there, and so is every package when the project's settings have an entry Skillshare can't read. Apply holds Pi's lock on the project file and checks both settings files and the package again right before it writes. Extensions in Pi's own extensions folders, including files linked there by extras, are listed read-only with where to change them; a project lists its own folder, which Pi reads only if it trusts the project, and the global one.

OpenCode registers the managed entry as a file URL in opencode.json or the existing opencode.jsonc, preserving comments and unrelated entries. Version 1 uses plugin; version 2 uses plugins. XDG_CONFIG_HOME and an absolute global OPENCODE_CONFIG are respected; ambiguous or unsupported overrides are rejected. OpenCode must be on PATH so Skillshare can choose the version's schema.

A local OpenCode source must already include its built entry (main, a string root export, or index.js) and required runtime dependencies. Skillshare does not run build scripts or install dependencies into the source. Registration is not proof the module loaded successfully; check OpenCode after reload.

Import accepts plain Pi package sources and, on Pi 0.99.2 or later, filtered object entries with supported sources and option shapes. Preview lists retained field names, never opaque values. Import changes neither native settings nor installed files. The original entry is kept in private Skillshare state; shared config stores only its digest. Sync/update retain the live entry. When uninstalling, Skillshare captures its latest rules and options; reinstall restores that object before native installation, avoiding a default-enabled window. Multiple restores in one Apply recognize only that Apply's own exact writes; unrelated settings changes still stop later restores. Keep private state with these bindings: a missing, modified, or cross-target record blocks restoration. On Windows, new registration directories use protected owner/SYSTEM ACLs. Existing directories and records must grant access only to the current user and privileged SYSTEM/Administrators principals; unsafe or unverifiable ACLs refuse import or restoration. Skillshare does not rewrite existing ACLs: retain the records and repair their access protection as the owner before retrying. Unresolved sources, ambiguous precedence, unsupported encoding, and local references Pi would normalize remain read-only. Plain OpenCode entries can be imported; filtered OpenCode entries are still rejected. Imported Pi packages are updated with pi update SOURCE in global mode, which keeps their settings entry; a project's are updated in Pi, because pi update also reaches global packages. Imported OpenCode v1 packages are updated in their native tool. OpenCode v2 global imports can use its native update command; project imports must be updated natively because the v2 update command is global.

skillshare plugin add ./cursor-plugin --target cursor --no-tui
skillshare plugin add ./agy-plugin --target agy --no-tui -p
skillshare plugin add ./pi-package --target pi --no-tui
skillshare plugin add ./opencode-package --target opencode --no-tui
skillshare plugin import npm:my-pi-package --from pi --name my-package --no-tui

Refs and explicit entries

Advanced options in Add plugin accept an optional Git ref and OpenCode entry. Leave them empty for the normal guided flow. The terminal wizard accepts the same flags; automation can use:

skillshare plugin discover obra/superpowers --source-ref v6.3.0 --json
skillshare plugin add owner/repo --source-ref v1.0.0 --target copilot --no-tui
skillshare plugin add ./package --entry dist/plugin.js --target opencode --no-tui
skillshare plugin update review --source-ref v1.1.0 --target claude --dry-run --json

Bindings record source_ref and the resolved commit. Installation uses the reviewed commit; check and update resolve the configured ref again, so a branch can advance while a commit remains pinned. --revision is a preview token, not a Git ref. --entry is relative to each candidate's package root and must already exist; it does not trigger a build or package-manager install.

Copilot and Antigravity CLI installs use reviewed local snapshots. Imports have no reviewed source for reinstall: after removal, install in the native client and sync again. Grok also requires native trust before install/reinstall. Skillshare never supplies native trust approval flags.

Compatibility and boundaries

Claude requires its native .claude-plugin/plugin.json package.
Codex accepts .codex-plugin/plugin.json and recognized portable root plugin.json packages. When a package has both, Codex installs from the portable root plugin.json, so Skillshare expects that manifest's version, or 1.0.0 when it has none. A Claude-only package is not silently converted.
Sources may contain a marketplace with local plugin entries. External catalog catalogs are merged by plugin name/path. Conflicting paths are rejected; external entries are reported with instructions to add their repository directly or install natively and import. Command-based sources are not auto-approved.
Complete source snapshots retain plugin scripts, assets, and safe relative symlinks (including AGENTS.md → CLAUDE.md). Absolute, escaping, dangling, cyclic, and .git-referencing links and special files are rejected; sources are limited to 20,000 files and 100 MiB.
Native installation is not proof of runtime activation. Restart/reload the Agent and complete authentication or hook trust in that Agent.
Codex runs codex from PATH. When it is not there, Skillshare tries Homebrew's /opt/homebrew/bin and /usr/local/bin, then the CLI inside the Codex desktop app (ChatGPT.app or Codex.app on macOS, %LOCALAPPDATA%\OpenAI\Codex\bin on Windows). Set SKILLSHARE_CODEX_CLI on a machine where Codex is elsewhere. An account with its own cli is not searched.
Codex native project installation is not provided by this adapter. Sync selection still works for global Codex installations.
Codex has no update command, so an update adds the plugin again from the refreshed snapshot. Adding always enables it, so a plugin disabled in Codex is skipped. An imported Codex plugin is updated with codex plugin marketplace upgrade NAME, which reinstalls every plugin Codex installed from that marketplace, as Codex also does when it starts.
An update skips a target it cannot reach and says why; the plugin's other Agents still update, and a skipped update stays pending for a later sync.
Imported plugins retain their original marketplace identity. check cannot infer release availability for an imported plugin without a source, except an npm package in Pi, which it checks against npm. If an imported Claude or Codex plugin's native marketplace is gone, sync and update skip that target and say so. This also happens on another machine where that marketplace was never added. Restore the marketplace in the Agent, or remove the target and add the plugin again from its source; Skillshare never moves an imported plugin to another source on its own.
Skillshare registers one marketplace per managed Claude/Codex plugin, named skillshare-<plugin>-<hash> (older installs keep skillshare-<hash>). Removing or excluding the plugin also removes that marketplace, even when the plugin is already gone; a failed cleanup is retried on the next sync. An update registers it again if it went missing. Same-name registrations at another path and imported plugins' marketplaces are left alone; snapshots and native caches are retained.
These registrations point at this machine's Skillshare state directory, in user and project settings alike. Sharing Agent settings through Git or a dotfile manager carries paths that do not exist elsewhere; add the plugin from its source on each machine instead.
Claude also reads a skill folder in its skills directory that has a plugin manifest as a plugin named <name>@skills-dir, and loads only one plugin per name. Adding a Claude plugin with the same name says so in the preview: Claude loads the plugin and skips the skill folder until one of them is renamed or removed.

The native lifecycle is exercised with Claude Code 2.1.276, Codex CLI 0.154.0, Pi 0.85.1, and Copilot CLI 1.0.86. Antigravity CLI 1.2.6 was checked with isolated native install/list/remove operations. OpenCode 1.18.31 is used to verify version-aware registration; the v2 schema is covered by fixture tests. Cursor and Antigravity filesystem lifecycles are tested in isolated directories, without claiming GUI runtime activation. Installed command capabilities and inventory schemas are checked at runtime; unsupported operations are blocked with an explanation.
