Code Engine Package Create (CLI)

Use this skill for package creation workflows, payload generation, and post-create mapping sync.

Intent

This skill covers lifecycle operations that are out of scope for app-runtime invocation skills:

• create new package shell
• publish first package content payload
• infer and normalize function input/output datatypes
• update app manifest.json packagesMapping entries after create

For in-app function invocation patterns, use ~/.agents/skills/code-engine/SKILL.md.

Primary Execution Path

Prefer community-domo-cli:

community-domo-cli --instance <instance> code-engine create-package --body-file payload.json

Fallback endpoint when CLI path is unavailable:

POST /api/codeengine/v2/packages

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.

Required Payload Shape

{
  "name": "My Package",
  "description": "Optional",
  "code": "// JS source",
  "environment": "LAMBDA",
  "language": "JAVASCRIPT",
  "manifest": {
    "functions": [
      {
        "name": "myFunction",
        "displayName": "My Function",
        "description": "",
        "inputs": [],
        "parameters": [],
        "output": {}
      }
    ],
    "configuration": {
      "accountsMapping": []
    }
  }
}

Create semantics:

• POST /api/codeengine/v2/packages creates a package or version payload target.
• For a new version on an existing package, include id and version in the create body and send full code/manifest payload.

Datatype Mapping Rules (Auto-Map)

When generating manifest.functions[].inputs/parameters/output, apply these defaults:

• payload, params, config, data, body, options => object
• names indicating counts/limits/offsets => decimal
• boolean-like names (is*, has*, enabled, required) => boolean
• identifiers/text fields (*id, name, query, message) => text
• unknowns => text
• output default => object

Use the same type value for type and dataType when both fields are present.

Post-Create Manifest Follow-up

After successful create, update app manifest.json packagesMapping:

• set packageId to created package id
• set version to returned version (or explicit target version)
• ensure each mapped function has matching parameters and output

If package ID/version changes, treat existing mapping as drift and sync immediately unless user requests otherwise.

Post-Create Verification (Required)

After create, verify target package/version before declaring success:

1. GET /api/codeengine/v2/packages/{packageId}
2. Confirm target version exists and includes expected function names.
3. Confirm function inputs/outputs have expected datatypes and nullability.

If create returns an incomplete version shell (for example missing function contracts), hand off to update flow:

• PUT /api/codeengine/v2/packages/{id}/versions/{version} via code-engine-update
• Re-run verification after update
