proto-sync

proto-sync is a skill for Claude Code from Gkrumbach07/openshell-dashboard. It costs 34 tokens per session (414 once invoked), scanned A, original, Apache-2.0.

A procedure for updating protocol definition files from NVIDIA’s OpenShell project and regenerating the Go code that represents them. Protocol files describe how software services communicate.

In plain words
What is it for?
Use it when OpenShell’s protocol definitions change, then rebuild the Go backend and check whether new service operations need dashboard support.
Why use it?
It keeps the dashboard’s generated Go code aligned with upstream API changes and reveals breaking changes during the build.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

Not installable on its own: it reads a path above its own folder, which only exists inside its repository. The line is git -C ../OpenShell fetch upstream main.

Install

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

proto-sync scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

SDK Sync

This repo no longer copies upstream proto files or regenerates local stubs. When OpenShell changes upstream, update the pinned Go SDK version and audit the affected handlers/models instead.

Note: proto-sync remains only as a discoverable alias for older prompts. The live workflow is SDK-first per ADR 0003.

Steps

1. Inspect upstream changes

git -C ../OpenShell fetch upstream main

Then compare the pinned SDK version against upstream:

  • sdk/go/openshell/v1/ for public client methods and resource shapes
  • sdk/go/openshell/v1/types/ for request/response field details
  • sdk/go/proto/sandboxv1/ only when the frontend policy protojson contract is involved

2. Bump the vendored SDK

cd backend
go get github.com/NVIDIA/OpenShell/sdk/go@<version-or-commit>
go mod tidy

3. Update call sites if the SDK shape changed

  • Handlers should keep calling app.sdk.<SubClient>()...
  • DTO shaping belongs in backend/internal/models/sdk_converters.go
  • Policy JSON compatibility belongs in backend/internal/models/policyproto.go
  • Only keep backend/internal/sdkclient/rawexec.go if the public SDK still lacks non-TTY stdin exec

4. Check for new user-facing capabilities

Compare upstream capabilities with the dashboard surface to see whether we should expose anything new. Prefer the public SDK. If a feature is missing in the SDK, document the exact gap before adding any workaround.

5. Commit

git add backend/go.mod backend/go.sum
git commit -m "build: bump OpenShell Go SDK"
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

proto-sync is a skill published in the GitHub repository Gkrumbach07/openshell-dashboard (2 stars, last pushed yesterday), licensed Apache-2.0. It adds 34 tokens to every session and 414 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
