OMP plugins ship their own .mcp.json, and that provider whitelists fields into
the canonical MCPServer shape the same way the other loaders do, so a plugin
bundling an integer-only server could set requestIdFormat and still have it
dropped before it reached a transport.
Extract the value parsing into parseRequestIdFormat() next to parseBoolean() in
discovery/helpers.ts and use it from all three OMP-owned loaders (native,
standalone mcp.json, omp-plugins), replacing the two hand-rolled copies.
Vendor providers (claude, claude-plugins, cursor, vscode, gemini, opencode,
windsurf) are deliberately untouched: they translate another tool's own server
list, where an OMP-specific key has no meaning.
Discovered plugin .mcp.json stdio servers launched relative command/cwd
values against the session cwd instead of the plugin's config directory,
breaking bundled ChatGPT/Codex plugins (e.g. Computer Use) with ENOENT
when spawning ./... from an unrelated cwd.
The claude-plugins and omp-plugins providers now resolve relative cwd and
path-like command (./ or ../) against the .mcp.json directory via a shared
resolvePluginStdioPaths helper; bare executables such as npx are left
untouched so PATH lookup still works.
Fixes#5330
Bug 1: capability loaders in src/discovery/builtin.ts only walked
.omp/ and ~/.omp/agent/, so extension packages registered via
extensions: in settings or --extension on the CLI shipped their
skills/, hooks/pre|post/, tools/, commands/, rules/, prompts/, and
.mcp.json silently — the docs at omp.sh/docs/extension-authoring
advertise the opposite. Add a new omp-plugins discovery provider that
scans every configured extension package directory for those
sub-trees, plus a small omp-extension-roots helper that resolves the
union of settings-driven and CLI-injected roots. main.ts injects CLI
extension paths via injectOmpExtensionCliRoots before any capability
load.
Bug 2: install was never registered as a top-level subcommand, so
`omp install ./my-extension` was rewritten to `launch install
./my-extension` and forwarded to the LLM as an initial prompt. Add a
top-level install command that routes local paths to plugin link and
remote specs to plugin install. Extract the command table into
src/cli-commands.ts so tests can introspect registered subcommands
without triggering cli.ts's top-level await.
Fixes#1496
