Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 C, and why

arbor copilot-instructions.md scanned grade C 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 yesterday.

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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

How it starts

The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

  • Verify that the copilot-instructions.md file in the .github directory is created. (Created with checklist for Tauri Lattice setup)

  • Clarify Project Requirements (Tauri v2 + Rust backend + Svelte frontend for Lattice Personal OS with Arbor integration, MCP tools, system tray - from previous query; no ask needed)

  • Scaffold the Project

  • Customize the Project

  • Install Required Extensions (None specified by get_project_setup_info for 'other'; skipped)

  • Compile the Project

  • Create and Run Task

  • Launch the Project

  • Ensure Documentation is Complete

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.
