Scans an existing application codebase and produces a snap-analysis.json file that captures everything needed to package the app as a snap: language/runtime, build system, entry points, system resource requirements, snap plugin recommendation, interface list, hook requirements, confinement type, and layout needs. Does…

Guides interactive publishing of snap packages to the Snap Store. Handles uploading new .snap files, registering snap names, releasing revisions to channels, and promoting existing revisions between channels. Operates hand-in-hand with the user, confirming every mutation before execution. Does NOT build snaps …

Trims and shrinks snap packages by editing snapcraft.yaml — never by hand-editing or repacking the .snap artifact. Analyzes a prebuilt .snap as ground truth, finds removal candidates (lint-flagged unused libraries, duplicates against the base and content/ extension snaps, internal duplicate libs, classic cruft)…
Skill Claude CodeCodex
Validates snap packages by provisioning a clean LXD container, installing with --dangerous, running all declared CLI apps and daemons, and capturing AppArmor/SecComp denials via snappy-debug. Records denials in snap-validation-results.json for snapcraft-author to act on — never patches snapcraft.yaml directly.…

Alternative producer of snap-analysis.json for OCI/container input: Docker Hub URLs, image references, docker save tarballs, or pre-extracted config.json + rootfs/. Downloads with skopeo, extracts via docker-to-snap (https://github.com/canonical/docker-to-snap), derives the build architecture from OCI metadata, and…

Entry point for packaging any application as a snap — start here. Takes a source-code project or OCI/Docker container input all the way to a validated, installable snap with correct interfaces by coordinating snap-analyzer (or snap-oci-analyzer), snapcraft-author, and snap-validator as sequential sub-agents: analyze →…

Pipeline stage, normally invoked by the snap-builder skill — to package an application as a snap, use snap-builder instead. Reads a snap-analysis.json file produced by snap-analyzer or snap-oci-analyzer and generates all files needed to package the application as a snap: snapcraft.yaml targeting core24 and snapcraft…
