${argv0} info

${argv0} list

The ctx.pear surface exposes selected Pear and Bare build/bundling packages

(pear-build, pear-bundle, bare-bundle-compile, etc.) when BARE_OS_BARE_MODULES
|
|
is enabled.
|
|
|

Many operations (full release, seeding, live sidecar IPC) currently delegate to
|
|
a host Pear sidecar (when available) following the same pattern as peerctl and
|
|
the P2P App Store.
|
|
|
|
Pear apps you create here are natural citizens of the P2P App Store:
|
|
- Stage your app with Pear tooling
|
|
- Publish it via appstore (or directly as a pear:// package)
|
|
- Other users can discover and run it
|
|
|
|
Use the pear-dev agent skill together with the appstore skill for
|
|
autonomous "build Pear app → publish to my store" workflows.
