A setup guide for customizing GitHub Copilot CLI, GitHub's command-line coding assistant. It explains when to use instructions, skills, hooks, MCP servers, custom agents, extensions, and plugins.

In plain words
What is it for?
Use it to configure repository instructions, path-specific guidance, skills, hooks, MCP servers, custom agents, extensions, or plugins for Copilot CLI.
Why use it?
It helps developers choose the right configuration mechanism instead of putting persistent rules, reusable workflows, tool safeguards, and external connections in the wrong place.

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.

ModelPer sessionOnce invoked
Fable 5 $0.00079 $0.03183
Opus 5 $0.00039 $0.01591
Sonnet 5 $0.00016 $0.00637
Haiku 4.5 $0.00008 $0.00318

Security

Grade B, and why

copilot-cli-configurator 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 400 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Copilot CLI Configurator

Set up and configure GitHub Copilot CLI customization surfaces. For creating skills, extensions, or MCP servers from scratch, use the dedicated skill-creator, create-extension, or mcp-builder skills instead.

Choosing the Right Customization

Goal Use
Copilot should always follow repo conventions Custom instructions
Repeatable workflow invoked on demand Skills
Guardrails, policy, or automation around tool use Hooks
External tools and data sources MCP servers
Specialist persona with constrained toolset Custom agents
Custom tools, programmatic hooks, model switching Extensions
Bundle of functionality to distribute Plugins

Read references/feature-comparison.md for detailed trade-offs between each surface.


1. Custom Instructions

Persistent guidance loaded at session start — tells Copilot how to behave across all tasks.

File Locations

Type File Location
Repository-wide copilot-instructions.md .github/
Path-specific *.instructions.md .github/instructions/ (supports subdirs)
Agent instructions AGENTS.md Repo root, cwd, or COPILOT_CUSTOM_INSTRUCTIONS_DIRS paths
Local/personal copilot-instructions.md ~/.copilot/

Also supports CLAUDE.md and GEMINI.md at repo root.

Path-Specific Instructions

Require YAML frontmatter with applyTo glob:

---
applyTo: "**/*.ts,**/*.tsx"
---

Use strict TypeScript with no `any` types. Prefer interfaces over type aliases.

Optional excludeAgent field to exclude "code-review" or "coding-agent".

When to Use

  • Style and quality rules (e.g., "prefer small PRs, write tests")
  • Repository conventions (e.g., "use pnpm, keep CHANGELOG.md updated")
  • Communication preferences (e.g., "explain tradeoffs briefly")

When NOT to Use

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
