github-codespaces-efficiency SKILL.md skillA
github-codespaces-efficiency from github/awesome-copilot is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add github/awesome-copilot/github-codespaces-efficiency@git:20260525.12666c9Pins git:20260525.12666c9 in mdr.lock. Pin the fingerprint instead.

Audit and improve GitHub Codespaces efficiency. Use this skill when a user wants faster Codespaces startup, lower Codespaces spend, slim devcontainers, right-size machines, tune idle timeout, or scope prebuilds to branches with sustained usage.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GitHub Codespaces Efficiency Use this skill as a lean entrypoint for GitHub Codespaces efficiency work. Inspect the repo, identify waste, and load only needed references. If no `.devcontainer/` exists yet, load [`references/codespaces.md`](./references/codespaces.md) and define a baseline before proceeding with the steps below. ## Use This Skill When - The user wants faster Codespaces startup or lower Codespaces spend. - The repo has a `.devcontainer/` or explicit Codespaces configuration questions. - The user asks for devcontainer optimization, machine sizing, prebuild strategy, or idle-timeout guidance. - The user is setting up Codespaces for the first time or needs help creating a new `.devcontainer/` from scratch. ## Load Only What You Need - [`references/codespaces.md`](./references/codespaces.md) — devcontainer, machine-sizing, prebuild, idle-timeout guidance, and reporting. - [`references/review-rubric.md`](./references/review-rubric.md) — load only for review passes. ## Core Workflow ### 1. Measure first ```bash find .devcontainer -maxdepth 2 -type f gh codespace list repo=$(gh repo view --json nameWithOwner --jq .nameWithOwner) …

How to install
mdr add github/awesome-copilot/github-codespaces-efficiency@sha256:933339dc228208baThe line at the top of this page pins the label git:20260525.12666c9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
