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

copilot-agent-factory 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 6d 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.

GitHub Copilot Instructions

Repository: Copilot Agent Factory
Generated: 2026-01-09

General Guidelines

  • Follow project conventions defined in AGENT.md
  • Use specialized agents via @agent-name for domain-specific tasks
  • Leverage MCP servers (git, filesystem) for template operations

Code Generation Standards

Always

  • Follow DRY and SOLID when developing new features (see AGENT.mdDRY and SOLID During New Feature Development)
  • Use {{placeholder}} convention (double braces, snake_case)
  • Follow standard agent template structure (Role → Knowledge → Standards → Boundaries → MCP)
  • Include concrete examples in templates
  • Add Boundaries section with ✅/⚠️/🚫 format
  • Keep documentation under 1000 lines
  • Test examples before adding to documentation
  • Use tables for structured data

Never

  • Use incorrect placeholder format (single braces, camelCase)
  • Create generic "helpful AI" instructions
  • Add placeholder/TODO sections to documentation
  • Include vague detection rules ("React project" vs "package.json with 'react'")
  • Break backwards compatibility without discussion
  • Skip approval gates in Feature Development Workflow
  • Duplicate content across templates without refactoring

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.
