This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
capacitor-app-upgrades from cap-go/capgo-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Routes and drives a Capacitor app upgrade across one or more major versions (4 to 9), including the required 8.4 to 8.5 iOS UIScene step before Capacitor 9 and Xcode 27. Detects the current version, plans the hop order (e.g. 6 to 7 to 8 to 8.5 to 9), runs `npx cap migrate` per hop, delegates each hop to its version skill, and verifies native builds between hops. Use for "upgrade Capacitor", "update to the latest Capacitor", "cap migrate", multi-version jumps, or when the target version is…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Capacitor App Upgrade (router)
Plan and run a Capacitor app upgrade one hop at a time, using the version-specific skill for each hop.
## When to Use
TRIGGER when:
- User wants to upgrade a Capacitor app and the start or target version is unknown or more than one major apart
- User asks for "the latest Capacitor" (decide stable 8.5.x vs prerelease 9 with them)
- Xcode 27 builds fail on a Capacitor 8.4-or-older app (needs the 8.5 UIScene step)
- `npx cap migrate` failed midway and the user needs to know where they are
Do not use:
- Plugin library repos -> `capacitor-plugin-upgrades`
- Cordova/PhoneGap apps -> `cordova-to-capacitor`
- CocoaPods to SPM only -> `cocoapods-to-spm`
## Live Project Snapshot
Current Capacitor packages from `package.json`:
!`node -e "const fs=require('fs');if(!fs.existsSync('package.json'))process.exit(0);const pkg=JSON.parse(fs.readFileSync('package.json','utf8'));const out=[];for(const section of ['dependencies','devDependencies']){for(const [name,version] of Object.entries(pkg[section]||{})){if(name.startsWith('@capacitor/'))out.push(section+'.'+name+'='+version)}}console.log(out.sort().join('\n'))"`

How to install
mdr add cap-go/capgo-skills/capacitor-app-upgrades@sha256:5a45c3e3a52e4ecfThe line at the top of this page pins the label git:20261011.86834d4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
