Copilot Configuration Manager

Manage all GitHub Copilot CLI configuration files from a single skill. Covers every config file the Copilot CLI reads — trusted folders, user settings, MCP servers, hooks, skills, custom agents, custom instructions, BYOK models, authentication, and session management.

What it does

Without this skill, an agent answers Copilot CLI configuration questions from training data alone, which can predate recent features and contain incorrect field names for several config files. The skill loads authoritative reference material for the exact config file the task requires, rather than loading everything at once.

It covers the CLI's global and project-level configuration, including settings, MCP and LSP servers, hooks, skills, custom agents, plugins, custom instructions, bring-your-own-key providers, sandboxing and permissions, built-in safety checks, session management, and OpenTelemetry export. It also bundles a script that shows the current configuration.

Where it applies

Use it when an agent edits or explains GitHub Copilot CLI configuration, in any client that loads skills.

Install

# Install globally for all detected agents
npx skills add CowboyLogic/ai-dev --skill client-config-copilotcli -g

# Install for a specific agent only
npx skills add CowboyLogic/ai-dev --skill client-config-copilotcli --agent copilot -g

# Preview what would be installed without installing
npx skills add CowboyLogic/ai-dev --skill client-config-copilotcli -g -l

Using gh copilot (Copilot CLI only)

gh copilot skill install CowboyLogic/ai-dev/skills/client-config-copilotcli

Verify installation

# List globally installed skills
npx skills ls -g

# Filter by agent
npx skills ls -g --agent copilot

Evaluation and history

In a benchmark run on 2026-04-26, the skill raised the assertion pass rate from 30% to 100%, with the largest gains on session management and bring-your-own-key setup. The detail is in the skill README, and the version history is in the CHANGELOG.
