Manual Capacitor Upgrades: A Skill for Agents

Where this fits

A developer is maintaining a Capacitor app that's been on version 6 for a year. The team wants to jump to version 8 to get the latest iOS and Android SDK support, but the interactive npx cap migrate command often misses manual steps like changing plugin APIs or updating build configurations. This skill gives an agent a deterministic, step-by-step procedure to upgrade the project manually—no interactive prompts, no guesswork.

Why agents benefit

• Explicit version detection: The agent reads the current @capacitor/core version from package.json before choosing the correct upgrade path, avoiding missteps from assumptions.
• Prerequisite validation: Each target version (5–8) includes required Node.js, Xcode, and Android Studio versions, so the agent can check the environment before making changes.
• Multi-version jumps: The skill supports sequential upgrades (4→5→6→7→8) and can handle direct jumps by chaining the procedures, ensuring no step is skipped.
• Manual execution: Since it avoids npx cap migrate, the agent has full control over every file change, making it easier to audit and roll back if something goes wrong.
• Clear scope boundaries: The skill explicitly excludes plugin library upgrades and non-Capacitor frameworks, preventing the agent from applying the wrong steps to unrelated code.

Practical scenarios

Upgrading a legacy Capacitor 4 app to 8

The skill walks the agent through each major version incrementally, updating dependencies, native project files, and configuration—all without relying on the interactive migrator.

CI/CD pipeline integration

When a pull request triggers an upgrade task, the agent can run the skill in a headless environment, verify prerequisites, and commit the changes automatically, providing a consistent upgrade path across branches.

Pre-release testing for a new Capacitor version

A developer wants to test a beta app against the next major version. The agent uses the skill to upgrade a copy of the project, runs the test suite, and reports any compatibility issues—all without affecting the main codebase.

Add it to your agent workflow

Install the skill directly from the capawesome-team repository:

npx skills add capawesome-team/skills --skill capacitor-app-upgrades

Once installed, invoke it in your agent's instructions. For example, to upgrade a project from Capacitor 6 to 7:

Use the capacitor-app-upgrades skill to upgrade the project to Capacitor 7.
First detect the current version, then follow the procedure for that target.

The skill provides the full procedure in its README, so the agent can follow it step by step. For more context on how this skill fits into the broader agent-skill ecosystem, see OpenAgentSkill.

Compare before adopting

Before adding this skill, compare it with other upgrade approaches: check if the repository is actively maintained (look at recent commits and issue responses), verify that the skill's manual steps align with your team's upgrade policy, and consider whether the official npx cap migrate might be sufficient for simpler upgrades. Also evaluate if the skill's scope matches your use case—it's strictly for Capacitor app projects, not plugins or other mobile frameworks.

Why it is worth tracking

With 44 stars and a clear, focused purpose, this skill addresses a real pain point for Capacitor developers who need reliable, auditable upgrades. Its maintenance by capawesome-team, a known entity in the Capacitor ecosystem, adds credibility. As Capacitor evolves, this skill will likely be updated for new major versions, making it a useful asset to monitor for any team that regularly upgrades mobile apps.
