Code Engine Update

Code Engine Package Update (CLI)

Use this skill for package update/version workflows and safe contract evolution.

Intent

This skill covers:

• update existing package code
• create a new version on an existing package id
• detect and handle mapping drift between package and app manifest
• validate datatype contract stability

For app-runtime invocation code, use ~/.agents/skills/code-engine/SKILL.md.

Primary Execution Path

Prefer community-domo-cli:

community-domo-cli --instance <instance> code-engine update-version <package_id> <version> --body-file payload.json

Fallback endpoint pattern:

POST /api/codeengine/v2/packages

with id and version set in body for versioned update behavior.

Release Safety Rule

Hard rule: never call any Code Engine release endpoint unless the user explicitly says "release".

• Do not infer release from context.
• Do not release as part of "finish", "publish", or "make it work".
• If release appears necessary, stop and ask for explicit release approval first.

Update/New-Version Behavior

Preferred create/update model:

1. Create a new package: POST /api/codeengine/v2/packages
2. Create a new version of an existing package: also POST /api/codeengine/v2/packages with id and version (for example 1.0.1) in the request body, including code/manifest payload.
3. Update an existing package version: PUT /api/codeengine/v2/packages/{id}/versions/{version}
4. If update fails because the target version is deployed/immutable, create a new version and then update that new version.

Execution notes:

• For new-version creation, prefer creating the version with full code+manifest payload immediately.
• Use PUT for subsequent changes to that specific version.

Always emit resulting packageId and version for downstream manifest sync.

Contract Safeguards

Before update publish:

• compare existing function aliases vs proposed aliases
• compare parameter names/types/nullability
• compare output shape/type
• flag breaking changes (removed required params, incompatible type changes)

When breaking change is intentional, require explicit migration note in generated output.

Drift Handling

After update:

• compare manifest.json packagesMapping against returned package id/version
• sync packageId, version, and parameter/output contracts when drift detected
• keep mapping aliases stable unless user requested rename

Checklist

• Correct update path selected (existing vs versioned)
• Input/output datatype contracts validated
• Breaking changes flagged clearly
• Manifest packagesMapping drift checked and synchronized
• Output includes updated package id/version and contract summary
