Riela Workflow Checkout

Use this skill when the user wants to install, import, check out, replace, or troubleshoot a riela workflow bundle from GitHub with workflow checkout.

When the target is a registry package id rather than a raw GitHub workflow directory URL, prefer the package lifecycle commands:

riela package install <package-id>
riela package list
riela package remove <workflow-name-or-package-id>

Use package list --output json to show installed package versions, package hashes/checksums, install ids, workflow destinations, and installed skill metadata. Use package remove --install-id <install-id> when multiple package records may match the same package or workflow name; removal deletes the recorded workflow install plus managed/projected package skills.

For running, listing, validating, inspecting, or monitoring existing workflows, use riela-workflow-run instead.

Command

Inside this repository, prefer:

riela workflow checkout <github-directory-url>

When riela is installed, prefer:

riela workflow checkout <github-directory-url>

Supported URL shape:

https://github.com/<owner>/<repo>/tree/<ref>/<workflow-directory-path>

Common source layout:

https://github.com/<owner>/<repo>/tree/<ref>/.riela/workflows/<workflow-name>

Behavior

• The source must be a public https://github.com directory URL.
• The final URL path segment becomes the workflow name and must pass the normal safe workflow-name rule.
• Branch or tag refs containing slashes are supported only when the GitHub directory can be resolved unambiguously. If multiple ref/path splits resolve, checkout fails with AMBIGUOUS_GITHUB_DIRECTORY_URL.
• Checkout fetches the remote directory into temporary staging, then validates it as a workflow bundle before writing the destination.
• Project scope is the default destination:

<project-root>/.riela/workflows/<workflow-name>

• If no project .riela exists, project-scope checkout creates:

<cwd>/.riela/workflows/<workflow-name>

• --project-root <path> or RIEL_PROJECT_ROOT can make the project scope explicit.
• Add --scope user to install under:

<user-root>/workflows/<workflow-name>

• --user-root <path> or RIEL_USER_ROOT can override the user root. The checkout registry is always written under the resolved user root, including project-scope checkouts.
• Add --workflow-definition-dir <path> to bypass scoped workflow catalogs and install directly under:

<path>/<workflow-name>

The registry record is still written under the resolved user root.

• Duplicate checkouts fail when the destination directory or registry record already exists.
• Add --overwrite only when the user explicitly wants replacement. The implementation validates the newly staged bundle before replacing the existing destination.
• Each successful checkout writes provenance under:

<user-root>/workflow-registry/checkouts/<scope>-<workflow-name>.json

The registry record includes the workflow name, source URL, scope, checkout time, and destination directory.

Text output prints the checked-out workflow name, scope, destination, and registry path. --output json returns workflowName, sourceUrl, scope, destinationDirectory, registryPath, validationStatus, and overwritten.

Standard Workflow

1. Confirm the source URL points to a single workflow directory containing workflow.json.
2. Choose scope:
   • Default to project scope unless the user asks for user-wide installation.
   • Use --scope user for user-wide installation.
   • Use --project-root or --user-root only when the destination root must be explicit.
   • Use --workflow-definition-dir only when the user wants a direct workflow definition directory destination.
3. Reject or remove conflicting remote-control options before running checkout:
   • Do not run against --endpoint.
4. For duplicates, run without --overwrite first unless the user explicitly requested replacement.
5. Use --output json when the result will be parsed or saved.
6. After checkout, optionally validate or list from scoped catalog lookup:

riela workflow validate <workflow-name>
riela workflow list

Examples

Project-scope checkout:

riela workflow checkout \
  https://github.com/<owner>/<repo>/tree/<ref>/.riela/workflows/<workflow-name>

User-scope checkout:

riela workflow checkout \
  https://github.com/<owner>/<repo>/tree/<ref>/.riela/workflows/<workflow-name> \
  --scope user

Replace an existing checkout after staged validation succeeds:

riela workflow checkout \
  https://github.com/<owner>/<repo>/tree/<ref>/.riela/workflows/<workflow-name> \
  --overwrite

Machine-readable result:

riela workflow checkout \
  https://github.com/<owner>/<repo>/tree/<ref>/.riela/workflows/<workflow-name> \
  --output json

Explicit project root:

riela workflow checkout \
  https://github.com/<owner>/<repo>/tree/<ref>/.riela/workflows/<workflow-name> \
  --project-root /path/to/project/.riela

Direct workflow definition directory:

riela workflow checkout \
  https://github.com/<owner>/<repo>/tree/<ref>/.riela/workflows/<workflow-name> \
  --workflow-definition-dir /path/to/workflow-definitions

Guardrails

• Use --workflow-definition-dir only for a direct local workflow definition directory; it writes to <path>/<workflow-name> instead of a scoped catalog.
• Do not combine checkout with --endpoint; checkout is local-only.
• Do not use checkout for arbitrary filesystem copies or non-GitHub sources.
• Do not assume a slash-containing branch or tag name is safe if checkout reports an ambiguous URL; ask the user for a less ambiguous ref or directory path.
• Do not add backend-specific checkout behavior for Codex, Claude, Cursor, OpenAI, or Anthropic. Backends are validated through the normal workflow bundle validation path after checkout.
• Do not use --overwrite unless the user asked to replace the existing checkout or approved the duplicate replacement.

Troubleshooting

• UNSUPPORTED_SOURCE_URL: use a public https://github.com directory URL.
• INVALID_SOURCE_URL: ensure the URL includes /tree/<ref>/<workflow-directory-path>.
• AMBIGUOUS_GITHUB_DIRECTORY_URL: the URL could resolve through multiple ref/path splits; use a less ambiguous ref or path.
• INVALID_REMOTE_DIRECTORY: confirm the URL resolves to a directory rather than a file and that the selected directory exists for the ref.
• INVALID_WORKFLOW_NAME: rename the remote workflow directory to a safe workflow name.
• DUPLICATE_CHECKOUT: rerun with --overwrite only if replacement is intended.
• USAGE: remove unsupported checkout options such as --endpoint.
• VALIDATION: inspect the remote bundle for invalid workflow.json, missing node payloads, missing prompt files, invalid step/node references, or unsafe workflow-local file paths.
• FETCH_FAILED: confirm the repository, ref, directory path, and network access.
