What it does

Frb Upgrade Docker is an agent skill from fzyzcjy/flutter_rust_bridge. Upgrade and publish the flutterrustbridge development Docker image, including toolchain bumps, image build fixes, candidate tags, and default-branch promotion.

Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Containers and Cross-platform mobile apps. It works with Docker, Flutter and Rust. The repository describes itself as: Flutter/Dart <- Rust binding generator, feature-rich, but seamless and simple. The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit 848e438. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- gh
- docker
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use gh and docker, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Frb Upgrade Docker loads about 798 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 346 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~45
When it runs · the whole SKILL.md, loaded when a task matches: ~798

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: frb-upgrade-docker
description: Upgrade and publish the flutter_rust_bridge development Docker image, including toolchain bumps, image build fixes, candidate tags, and default-branch promotion.

1 Scope the PR

Put every development-image upgrade in an independent PR targeting master. Make it the first PR in a toolchain-upgrade chain.
Include all Docker-owned changes required by the upgrade:
- .devcontainer/Dockerfile toolchain and system packages;
- .github/workflows/publish_dev_docker.yaml build, test, and publication logic;
- image metadata tests, tag derivation, and Docker-specific supporting code.
Leave FRB runtime fixes, generated scaffolds, and example migrations to later PRs.
Read frb-docker for local use and frb-dev-env before running repository commands in a container.

2 Build before merge

Before pushing the Docker upgrade PR, follow frb-docker's local Dockerfile validation workflow with a freshly built image. Do not validate with a stale per-worktree container.
Make Dockerfile and publish-workflow PRs automatically build and smoke-test native linux/amd64 and linux/arm64 images with push: false.
Do not expose registry credentials to untrusted pull-request code.
Derive image tags from Dockerfile ARG values instead of duplicating versions.
Verify Flutter, Dart, Rust, the pinned nightly and wasm target, Node, Yarn, wasm-pack, Chrome, ChromeDriver, and ./frb_internal --help.
For a manual build-only check, run:

shell

gh workflow run publish_dev_docker.yaml --ref <branch> -f publish=false

3 Publish safely

If later PRs need the image before merge, let a maintainer explicitly publish only an immutable candidate-pr-<number>-sha-<short_sha> tag. Reject a conflicting existing tag; allow only an identical retry.
Never update latest, canonical version tags, or stable SHA tags from pull-request code.
Publish stable tags only from a push to master. A manual stable dispatch must check out the current remote master head, not an older reachable commit.
After merge, publish from master:

shell

gh workflow run publish_dev_docker.yaml --ref master

Stable publication may then update:
- latest;
- flutter-<flutter>-rust-<rust>-nightly-<nightly>;
- the version-plus-code and stable SHA tags.

4 Verify and hand off

Inspect the candidate when used, then inspect the canonical tag and latest after merge:

shell

docker buildx imagetools inspect fzyzcjy/flutter_rust_bridge_dev:<tag>
docker inspect fzyzcjy/flutter_rust_bridge_dev:latest \
  --format '{{ index .Config.Labels "org.opencontainers.image.revision" }}'

Require linux/amd64 and linux/arm64; ignore BuildKit attestation entries reported as unknown/unknown.
Merge latest master into the remaining chain, switch it from any candidate to the canonical tag, and do not merge a consumer before that tag exists.
Diagnose Docker Hub login, per-platform pushes, and manifest creation separately.
If local latest is stale, use the exact candidate/canonical tag or build the Dockerfile locally; do not generate locks or scaffolds with the wrong toolchain.
