What is vscode-copilot-sync copilot-instructions.md?

Repository instructions for PowerShell scripts that copy GitHub Copilot resources from the awesome-copilot repository into user and project locations. PowerShell is a Windows command-line scripting language.

Use them when configuring the sync, installing resources for all VS Code sessions, or adding agents, instructions, hooks, workflows, and skills to a specific repository.

They clarify which scripts to run, where resources belong, and how errors and logs should be handled, reducing setup mistakes.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01186	$0.01186
Opus 5.5	$0.00474	$0.00474
Sonnet 5.5	$0.00237	$0.00237
Haiku 4.5	$0.00119	$0.00119

Security

Grade A, and why

vscode-copilot-sync copilot-instructions.md scanned grade A with 0 findings 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 15d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Copilot Instructions

This repository contains PowerShell scripts that sync Copilot resources from github/awesome-copilot to a local machine and distribute them to the right VS Code/Copilot locations.

Script Workflow

Scripts are designed to be run in this order:

configure.ps1                      # Main entry point (chains all steps)
scripts/sync-awesome-copilot.ps1   # 1. Clone/pull github/awesome-copilot → ~/.awesome-copilot/
scripts/init-user.ps1              # 2. User-level resources → ~/.copilot/{agents,instructions,skills}/
scripts/init-repo.ps1              # 3. Interactive per-repo setup → .github/

Resource scopes:

User-level (all Copilot harness sessions, no .github/ needed): Agents → ~/.copilot/agents/; Instructions → ~/.copilot/instructions/; Skills → ~/.copilot/skills/
Per-repo (committed to .github/): Agents → .github/agents/; Instructions → .github/instructions/; Skills → .github/skills/. Hooks and workflows are optional catalog categories.

MCP server configuration is not managed by this repository. Workspace MCP configuration is .mcp.json; user configuration is $COPILOT_HOME/mcp-config.json or ~/.copilot/mcp-config.json when COPILOT_HOME is unset.

Key Conventions

Error Handling

All scripts use $ErrorActionPreference = 'Stop' so errors terminate rather than prompt. Use try/catch blocks for recoverable errors — do not rely on error preference for expected failure paths.

Logging & Common Primitives

All shared primitives, path assertions, and logging functions reside in scripts/lib/Common.ps1. Use Log or Write-CopilotLog (not raw Write-Host):

Log "Message here"           # INFO (Cyan)
Log "Something wrong" 'WARN' # Yellow
Log "Done!" 'SUCCESS'        # Green
Log "Failed" 'ERROR'         # Red

Dry-Run Pattern

Every destructive operation must be guarded by $DryRun:

if ($DryRun) { Log "[DryRun] Would do X"; return 'would-copy' }
# actual operation here

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.
