Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is sybrew/troy's own configuration. It tells GitHub Copilot how to work on troy itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything troy configures →

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.

Security

Grade A, and why

troy local.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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Local Workspace Rules

  • .local/ is gitignored. Agent Grep and Glob cannot search it, even with an explicit path. .cursorignore !.local/** does not fix those tools. Use Read/Write with an explicit path, or Shell (Get-ChildItem, Select-String, rg --no-ignore-vcs). A zero Grep/Glob result does not mean .local is empty.
  • Treat .local/ as private workspace-only context.
  • Do not expose .local/ details or related-repository context in public-facing instructions or responses unless the user asks for them.
  • Keep private workspace-only guidance, partner or outreach rules, and related-repository cross-references in .local/.instructions/*.instructions.md, not in tracked repo instruction files.
  • Troy is a monorepo. When local guidance refers to Troy, Troy Server, Troy Client, Troy Client Daemon, or Troy Installer, keep the target package explicit.
  • Treat support, partner, or outreach inquiries as first-class engineering work.
  • These inquiries may require code inspection, reproduction, remediation, product explanation, or patches.
  • Do not assume an inquiry is explanation-only.
  • Diagnose whether the issue is configuration, expected behavior, a defect, a documentation gap, or a feature gap before recommending action.
  • Fix the cause, not the symptom.
  • Prefer the smallest safe remediation that prevents end-user issues.
  • If the issue cannot be resolved from current context, gather the missing evidence or ask precise follow-up questions.

Load .local instruction files

.local/.instructions/*.instructions.md is not auto-injected. Do not Read them all.

  1. From the repo root, extract YAML frontmatter only (commands below).
  2. Read the files whose applyTo matches the current paths, or whose description matches the task. Files with no applyTo still match on description.
  3. Do not paste the extract or private bodies into chat.

Windows

Get-ChildItem -LiteralPath '.local/.instructions' -Filter '*.instructions.md' | ForEach-Object {
	$raw = [System.IO.File]::ReadAllText($_.FullName)
	if ($raw -match '(?s)\A---\r?\n(.+?)\r?\n---') {
		Write-Output ("FILE: {0}`n{1}`n" -f $_.Name, $Matches[1].Trim())
	}

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.
