What it does

Overview is an agent skill from projectbluefin/finpilot. Architecture, repository layout, and file map for this template. Use when orienting to the repository, tracing how the image is assembled, or deciding which skill covers a task.

Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Build your own custom Bluefin. The licence is Apache-2.0.

When your agent uses it

  • Orienting to the repository
  • Tracing how the image is assembled
  • Deciding which skill covers a task

Example prompts

  • “/overview”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit 8e0eb5d. 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:

    • just

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

Overview loads about 740 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 345 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~740

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.

Overview

This repository builds a bootc operating system image by assembling OCI layers rather than by modifying an existing image. Bluefin, Aurora, and Bluefin LTS are built the same way, so the desktop configuration here is the one they ship.

How the image is assembled

The Containerfile is the source of truth, and it is deliberately verbose. It defines three things:

  1. Context stage (ctx) — combines the local build/ and custom/ directories with files pulled from two OCI images:

    • ghcr.io/projectbluefin/common — the shared desktop configuration, branding, and the Brew/Flatpak/ujust plumbing
    • ghcr.io/ublue-os/brew — the Homebrew integration
  2. Base image — the FROM line. It defaults to Fedora Silverblue and is the only place the base is chosen. just build reads the image name and tag from it; the Fedora major is read from the base image itself during the build.

  3. Phases — each build script runs in its own RUN block, in the order the Containerfile names them. build/README.md lists them.

Upstream

The template consumes Project Bluefin's shared infrastructure rather than copying it:

  • projectbluefin/common — the shared runtime layer and the lifecycle label workflow
  • projectbluefin/actions — the reusable workflows for image build, promotion, sync, PR validation, and Renovate
  • ublue-os/brew — the Homebrew integration

Changes stay in this repository. ublue-os/* is read-only.
