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.
Default Workflow
- Inspect the working tree and identify touched surfaces: Rust, Python,
Node.js, Go, WebAssembly, C FFI, CLI/config, docs, or integration patches.
- Run the bundled helper in dry-run mode before editing:
python skills/nemo-relay-migrate-from-flow/scripts/migrate_from_nemo_flow.py <path> --rename-paths
- Review the reported text edits and path renames. If the scope is correct,
rerun with
--write --rename-paths.
- Apply language-specific cleanup for package manager lockfiles, generated
artifacts, and public API examples.
- 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 and WebAssembly:
nemo-flow-node -> nemo-relay-node,
nemo-flow-wasm -> nemo-relay-wasm, and 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, .nemo-flow -> .nemo-relay,
~/.config/nemo-flow -> ~/.config/nemo-relay, NEMO_FLOW_* ->
NEMO_RELAY_*, and x-nemo-flow-* -> x-nemo-relay-*
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 or
nemo-relay-wasm. 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 patch
names.
Automation Helper
Use scripts/migrate_from_nemo_flow.py for first-pass edits. It:
- runs as a dry run unless
--write is passed
- skips common vendor, build, cache, and generated directories
- skips lockfiles unless
--include-lockfiles is passed
- 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
Run it from either the source repository or the user's target project:
python skills/nemo-relay-migrate-from-flow/scripts/migrate_from_nemo_flow.py . --rename-paths
python skills/nemo-relay-migrate-from-flow/scripts/migrate_from_nemo_flow.py . --write --rename-paths
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 or WebAssembly 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.
