Add or change a public NeMo Relay runtime API across Rust and affected language bindings when no more specific maintainer skill owns the domain. Do not use for middleware additions, internal refactors, binding-local fixes, or docs-only changes.

The file

We split this skill into the rules it gives an agent

8 rules. About 0 are common, 6 are distinctive, and 2 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈6

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  1. Distinctive:

    Use this skill when a change affects the public runtime surface and must stay in parity across the Rust core, FFI, and one or more bindings.

  2. Distinctive:

    Do not use this skill for:

    line 13
  3. Very specific:

    Update crates/ffi and its generated header only when the capability is exposed through the C ABI or Go binding.

    line 27
  4. Distinctive:

    Update each binding that exposes the capability.

    line 30
  5. Distinctive:

    Update Python wrapper modules, Go shorthand packages, typed helpers, or adaptive/plugin helpers if the new behavior belongs there.

    line 33
  6. Distinctive:

    Update reference docs, language-binding docs, and examples when the public surface or expected usage changed.

    line 36
  7. Distinctive:

    Follow the repository validation policy for the surfaces whose public or observable behavior changed.

  8. Very specific:

    If tool execution is affected, does every callback, continuation, managed return, and manual end surface use the canonical …

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Add a Binding Feature

Use this skill when a change affects the public runtime surface and must stay in parity across the Rust core, FFI, and one or more bindings.

Do not use this skill for:

  • Internal-only core refactors with no public API change
  • New middleware contracts, which use the middleware-specific workflow
  • Binding-local bug fixes that do not change shared behavior
  • Docs-only or example-only updates

Implementation Order

  1. Core Rust Implement the behavior first in crates/core/src/api/ and related core modules such as crates/core/src/api/runtime/, crates/core/src/codec/, or crates/core/src/json.rs.
  2. FFI / shared C surface, when affected Update crates/ffi and its generated header only when the capability is exposed through the C ABI or Go binding.
  3. Language-native bindings Update each binding that exposes the capability; leave unrelated bindings unchanged.
  4. Language wrapper helpers Update Python wrapper modules, Go shorthand packages, typed helpers, or adaptive/plugin helpers if the new behavior belongs there.
  5. Docs and examples Update reference docs, language-binding docs, and examples when the public surface or expected usage changed.
  6. Validation Follow the repository validation policy for the surfaces whose public or observable behavior changed.

Parity Checklist

  • Core function with doc comment in crates/core/src/api/
  • Runtime callback/state, codec, JSON, or event/tool/LLM/scope types added in the relevant core module if needed
  • FFI wrapper and generated header updated if the C ABI changes
  • Python native binding, wrapper, docstring, and stubs updated if exposed
  • Go wrapper and shorthand package updated if the experimental Go surface exposes the capability
  • Node.js native binding and wrapper updated if exposed
  • Typed wrapper or adaptive/plugin helper surfaces updated when applicable
  • Meaningful tests added in every affected language surface
  • SPDX license header on any new files
  • Relevant pages under docs/reference/ updated
  • README.md, docs/getting-started/, or binding-level READMEs updated if behavior differs by language
  • Relevant getting-started, README, or example docs updated if usage changed

Decision Points

Lock these before implementing:

  • Which bindings actually expose the new surface?
  • Is the change part of the plain JSON API, typed wrappers, adaptive/plugin helpers, or observability helpers?
  • Does the new API need manual lifecycle and managed execute variants, or only one of them?
  • Does the new behavior change event fields, metadata, or scope expectations?
  • If tool execution is affected, does every callback, continuation, managed return, and manual end surface use the canonical ToolExecutionResult contract and preserve its opaque annotation?
  • Are docs/examples required because the intended usage changed?

Key References

  • Architecture: docs/about-nemo-relay/architecture.mdx
  • Reference index: docs/reference/api/index.mdx
  • Getting started and binding status: README.md, docs/getting-started/quick-start/index.mdx, docs/reference/support-matrix.mdx
  • Typed wrappers and codecs: docs/integrate-into-frameworks/using-codecs.mdx, docs/integrate-into-frameworks/provider-codecs.mdx
  • Adaptive config/plugins: docs/configure-plugins/about.mdx, docs/build-plugins/about.mdx, docs/configure-plugins/adaptive/configuration.mdx
  • Existing pattern: follow a surface already implemented across core, FFI, Python, Go, and Node.js rather than inventing a new shape

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
