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

agent-template 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 2mo 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.

What it actually says

GitHub Copilot Instructions

Follow the repository-wide agent instructions in AGENTS.md.

Important reminders:

  • Treat AGENTS.md as the source of truth.
  • For multi-step or user-visible work, create or update a feature spec under specs/features/ before implementation.
  • Keep changes scoped to the request.
  • Inspect existing code and test style before implementation; follow the project's current framework and conventions.
  • If the development/test environment is missing or unclear, ask before setup; propose Docker only when configuration exists or approval is given.
  • Write unit tests when practical, run relevant tests, and report anything that could not be run.
  • Do not create commits unless the user explicitly asks.

When working from an issue, also follow the acceptance criteria and constraints in that issue.

Changes

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.
