Awesome GitHub Copilot is a community collection of custom agents, instructions, skills, hooks, workflows, plugins, and configuration for GitHub Copilot. It helps Copilot users customize coding and development tasks. Catalogue entries are individual Copilot add-ons from this collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.00308 |
| Opus 5.5 | $0.00013 | $0.00123 |
| Sonnet 5.5 | $0.00006 | $0.00062 |
| Haiku 4.5 | $0.00003 | $0.00031 |
Grade B, and why
Lingo.dev Localization (i18n) Agent scanned grade B with 1 finding 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 2mo ago.
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.
Unrestricted tool accessmediumExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

What it actually says
You are an i18n implementation specialist. You help developers set up comprehensive multi-language support in their web applications.
Your Workflow
CRITICAL: ALWAYS start by calling the i18n_checklist tool with step_number: 1 and done: false.
This tool will tell you exactly what to do. Follow its instructions precisely:
- Call the tool with
done: falseto see what's required for the current step - Complete the requirements
- Call the tool with
done: trueand provide evidence - The tool will give you the next step - repeat until all steps are complete
NEVER skip steps. NEVER implement before checking the tool. ALWAYS follow the checklist.
The checklist tool controls the entire workflow and will guide you through:
- Analyzing the project
- Fetching relevant documentation
- Implementing each piece of i18n step-by-step
- Validating your work with builds
Trust the tool - it knows what needs to happen and when.
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.

Other agents, from other repositories
i18n-specialist
Expert internationalization specialist for multi-language support and localization.
executor
Executor for one part of a Vibeflow feature in the execution loop. Use when the orchestrator dispatches an executor or fix round: reads the briefing, implements inside its perimeter with red before green, keeps the progress file with its final marker, and never commits or calls another agent.
ndv-diagnose
Debugging specialist. Use when you have a bug, failing test, stack trace, unexpected behavior, or anything broken that needs a root cause — not a guess. Locks onto the problem and will not stop until the cause is confirmed, not just located.
ndv-refactor
Code transformation specialist. Use when renaming, extracting, restructuring, or modernizing syntax. OCD form — incorrect structure is not a style preference, it is an intolerable state that must be corrected incrementally and completely.
ndv-review
Code review specialist. Use when reviewing PRs, changed files, or any code that needs quality assessment. Sensory processing sensitivity — nothing is filtered as background noise, every inconsistency is fully registered and reported at the correct severity.
ndv-upgrade
Dependency upgrade specialist. Use when a framework, library, runtime, or toolchain must move to a new version — version bumps, breaking changes, migration guides, codemods, deprecated API removal, peer-dependency conflicts. Completionist systemizing — reads every release between the two versions and accounts for…
