GitHub Copilot Governance & Instructions Sync
Sync .github/copilot-instructions.md across your team with one command. Enforce governance policies, maintain audit trails, and keep every developer aligned with organizational standards. Built for GitHub Copilot.
The Copilot instructions drift problem
When every developer configures Copilot differently, you lose consistency, security, and visibility across your organization.
Inconsistent copilot-instructions.md
Every developer has different instructions. Some projects have thorough documentation, others have none. AI behaves inconsistently across your codebase.
Uncontrolled Context
Copilot indexes whatever it finds. Without governance, sensitive files may be indexed or AI may reference internal documentation inappropriately.
No Team Sync
Custom prompts and instructions live on individual machines. When someone leaves, institutional knowledge walks out the door with them.
Governance features for Copilot
GAL provides the governance layer that sits between your organization and Copilot, ensuring every session operates within approved boundaries.
Instructions Sync
Pull approved .github/copilot-instructions.md and settings with a single command. Keep every developer on the same configuration.
Governance Policies
Define org-wide rules for what Copilot can and cannot do. Block sensitive file indexing, restrict context boundaries, enforce security standards.
CLI Integration
GAL wraps your Copilot workflow. One command to sync, one command to verify compliance, zero friction for developers.
Team Management
Invite team members, manage access levels, and ensure everyone runs the same baseline configuration across all projects.
How Copilot instructions sync works
Get your entire team on the same Copilot configuration in under 5 minutes.
Connect Your Organization
Install the GAL GitHub App to connect your repositories. GAL auto-discovers all Copilot configurations across your codebase.
Define Approved Config
Create your organization's approved .github/copilot-instructions.md and Copilot settings in the GAL dashboard.
Developers Sync
Team members run `gal sync --pull` to get the approved configuration. Updates are distributed instantly when policies change.
One command to governance
Developers sync their Copilot configuration with a single CLI command. No manual file copying, no Slack threads, no merge conflicts.
# Install the GAL CLI npm install -g @scheduler-systems/gal # Authenticate with your GitHub account gal auth login # Pull the organization's approved Copilot configuration gal sync --pull --agent copilot # Output: # ✓ .github/copilot-instructions.md updated (v3 → v4) # ✓ .github/copilot-settings.json updated (2 new ignore patterns) # # Sync complete. Copilot is now on approved baseline.
Who uses GAL for Copilot governance
Security Teams
Define rules for what files Copilot can index. Prevent sensitive data exposure. Ensure every Copilot session follows security policy.
Engineering Leads
Distribute coding standards via copilot-instructions.md. Share custom prompts for common workflows. Onboard new developers faster with pre-configured instructions.
Compliance Officers
Maintain audit trails of what configurations were deployed. Demonstrate governance during SOC 2 or ISO 27001 audits.

| Capability | Manual (Git/Dotfiles) | GAL |
|---|---|---|
| Push updates to team | No (pull only) | Yes |
| Multi-repo support | Manual symlinks | Org-wide sync |
| Audit trail | Git log only | Full visibility |
| Enforcement | None | Policy layer |
| Setup time | Hours per repo | 5 minutes |
Frequently asked questions
Does GAL replace Copilot?
No. GAL is a governance layer that works WITH Copilot. Your developers still use Copilot normally. GAL ensures they all use the same approved instructions and policies.
What files does GAL sync for Copilot?
GAL syncs .github/copilot-instructions.md (project instructions) and Copilot settings stored in .github/copilot-settings.json.
How do developers update their config?
Developers run `gal sync --pull --agent copilot` to get the latest approved configuration. You can also set up automated sync on a schedule or via CI/CD.
Can developers override the approved config?
With the Convenience tier, developers can override locally. With the Enforcement tier, GAL actively blocks operations outside approved boundaries regardless of local settings.
Does GAL work with other AI coding agents?
Yes. GAL supports Claude Code, Cursor, GitHub Copilot, Windsurf, Gemini Code Assist, and Codex. You define policy once, and GAL translates it to each platform's configuration format.
