AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a structured workflow and automation helper for migrating existing NeMo Flow applications, documentation, and configurations to NeMo Relay. It focuses on mechanical renaming across multiple programming languages and surfaces, including Python, Rust, Node.js, Go, C FFI, and CLI configurations, while ensuring safe handling of project-specific settings and dependencies.

What it does

  • Identifies and renames NeMo Flow identifiers to NeMo Relay across source code and documentation.
  • Provides a dry-run mode to review all proposed file renames and text edits before application.
  • Handles language-specific updates for package managers, imports, and build configurations.
  • Flags legacy configuration files that require manual migration for user review.
  • Verifies the migration through targeted search and language-specific test execution.
  • Ensures safe file system operations by requiring explicit confirmation of the target root.

When to use it

  • When upgrading an existing project from NeMo Flow to NeMo Relay.
  • When updating documentation or examples to reflect the NeMo Relay branding and API structure.
  • When migrating cross-language repositories that contain Python, Rust, Node.js, or Go code.
  • When needing to update CLI configurations or environment variables from NeMo Flow to NeMo Relay.

Advantages

  • Reduces manual effort for large-scale codebase renames.
  • Provides a safe, review-first approach with dry-run capabilities.
  • Supports a wide range of languages and integration surfaces.
  • Prevents accidental modification of sensitive or project-local configuration files.
  • Includes built-in verification steps to ensure code integrity post-migration.

Usage examples

“I need to migrate my project at /home/user/my-app from NeMo Flow to NeMo Relay. How do I start?”
The agent will guide you to set the SKILL_DIR and TARGET_PATH variables, then execute the migration script in dry-run mode to generate a report of all pending changes for your review.
“I have reviewed the dry-run report for my migration. How do I apply the changes?”
The agent will instruct you to run the migration script with the --write and --confirm-root flags to safely apply the renames and edits to your project files.

Documentation by NVIDIA Corporation and Affiliates

Migrate From NeMo Flow To NeMo Relay

Use this skill when a user has existing NeMo Flow code or documentation and wants it converted to NeMo Relay. Treat the migration as a mechanical rename plus language-specific validation, not a behavior rewrite. Keep compatibility exceptions explicit before applying broad renames.

Default Workflow

  1. Inspect the working tree and identify touched surfaces: Rust, Python, Node.js, Go, C FFI, CLI/config, docs, or integrations.

  2. Resolve SKILL_DIR to the absolute directory containing this SKILL.md and TARGET_PATH to the source repository or target project. Run the bundled helper in dry-run mode before editing: python3 "$SKILL_DIR/scripts/migrate_from_nemo_flow.py" "$TARGET_PATH" --rename-paths

  3. Review the reported text edits, path renames, and legacy project configuration warnings with the user. Do not migrate project-local .nemo-flow/config.toml or .nemo-flow/plugins.toml into .nemo-relay. Move those settings manually to a supported user or explicit configuration path after review.

  4. Obtain explicit confirmation for the resolved target root, then rerun with --write, --rename-paths, and --confirm-root "$TARGET_PATH".

  5. Apply language-specific cleanup for package manager lockfiles, generated artifacts, and public API examples.

  6. Search for remaining Flow names and verify the affected language surfaces.

Mechanical Rename Map

  • Brand and repository: NeMo Flow -> NeMo Relay, NeMo-Flow -> NeMo-Relay

  • Python: nemo-flow -> nemo-relay, nemo_flow -> nemo_relay, python/nemo_flow -> python/nemo_relay

  • Rust: nemo-flow -> nemo-relay, nemo-flow-adaptive -> nemo-relay-adaptive, nemo_flow:: -> nemo_relay::

  • Node.js: nemo-flow-node -> nemo-relay-node, including related entry points such as /typed, /plugin, /adaptive, and /observability

  • Go: github.com/NVIDIA/NeMo-Flow/go/nemo_flow -> github.com/NVIDIA/NeMo-Relay/go/nemo_relay, package aliases nemo_flow -> nemo_relay, and source directories go/nemo_flow -> go/nemo_relay

  • C FFI: nemo_flow.h -> nemo_relay.h, nemo_flow_* -> nemo_relay_*, NemoFlow* -> NemoRelay*, and NEMO_FLOW_* -> NEMO_RELAY_*

  • CLI/config: nemo-flow -> nemo-relay, ~/.config/nemo-flow -> ~/.config/nemo-relay, NEMO_FLOW_* -> NEMO_RELAY_*, and x-nemo-flow-* -> x-nemo-relay-*. Do not blindly rename project-local .nemo-flow/config.toml or .nemo-flow/plugins.toml into .nemo-relay; those files require manual migration to a supported user or explicit configuration path.

Do not replace bare flow, Flow, or FlowError. Those can be domain words or intentional compatibility names.

Language Cleanup

  • Python: update pyproject.toml, imports, type stubs, integration package paths, extras, and native module names. Regenerate or refresh lockfiles with the user's package workflow after source edits.

  • Rust: update Cargo.toml crate names, workspace dependencies, package references, and use nemo_relay::... imports. Let Cargo regenerate Cargo.lock when dependencies changed.

  • Node.js: update package.json, workspace names, package-lock entries, native addon artifact names, and imports from nemo-relay-node. Run the package manager to refresh locks.

  • Go: update go.mod, import paths, package declarations, aliases, and any local directory layout under go/nemo_relay.

  • C FFI: update header includes, exported symbol names, status and callback type names, macro constants, loader paths, and downstream bindings.

  • Docs and examples: update badges, package install commands, repository links, hosted docs URLs, CLI commands, config paths, and integration names.

Automation Helper

Use $SKILL_DIR/scripts/migrate_from_nemo_flow.py for first-pass edits. The helper:

  • runs as a dry run unless --write is passed

  • skips common vendor, build, cache, and generated directories

  • skips lockfiles unless --include-lockfiles is passed

  • skips symbolic links and credential-bearing dotenv files

  • detects project-local .nemo-flow/config.toml and .nemo-flow/plugins.toml, leaves them unchanged, and reports that they require manual migration to a supported user or explicit configuration path

  • requires the reviewed target root to be repeated with --confirm-root before writing, and refuses filesystem-root or home-directory writes

  • anchors writes and renames to verified directory handles without following symbolic links, and refuses write mode on platforms that cannot provide those guarantees

  • uses atomic no-replace path renames and exits nonzero when any requested mutation fails

  • can report or perform path renames with --rename-paths

  • rewrites only explicit NeMo Flow identifiers, package names, repository names, config paths, headers, environment variables, and FFI type prefixes

The helper does not classify arbitrary JSON, YAML, TOML, or INI files as secret. Review every configuration file in the dry-run report. If any reported file is unreviewed or credential-bearing, do not use --write on that root. Apply the reviewed changes manually and leave secret-bearing files untouched without reading or displaying their values.

Set shell-safe absolute paths before invoking the helper. Replace the example values with the resolved skill directory and either the source repository or the user's target project:

SKILL_DIR="/resolved/absolute/path/to/nemo-relay-migrate-from-flow"
TARGET_PATH="/resolved/absolute/path/to/target-project"

python3 "$SKILL_DIR/scripts/migrate_from_nemo_flow.py" "$TARGET_PATH" --rename-paths
python3 "$SKILL_DIR/scripts/migrate_from_nemo_flow.py" "$TARGET_PATH" \
  --write --rename-paths --confirm-root "$TARGET_PATH"

Use --include-lockfiles only when the user wants lockfiles edited directly; otherwise regenerate them with Cargo, uv/pip, npm, or Go tooling.

Verification

  • Search for remaining explicit Flow identifiers: rg -n "NeMo Flow|NeMo-Flow|nemo_flow|nemo-flow|NEMO_FLOW|NemoFlow|nemo_flow\\.h|nemo_flow_"

  • Run targeted tests for every affected language surface.

  • For Rust changes, run cargo test or the repository's Rust test recipe.

  • For Python changes, run the relevant import check and tests in the target environment.

  • For Node.js changes, run package install, type checks, and package tests.

  • For Go changes, run go test ./... from the updated module.

  • For docs-only migrations, build or link-check docs if the site navigation, install commands, or API references changed.
