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

agentregistry 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

Read and follow AGENTS.md for repo-local coding and workflow guidance.

Before creating or updating a pull request, review the PR authoring rules in AGENTS.md and follow .github/PULL_REQUEST_TEMPLATE.md.

Keeping the PR Description Up-to-Date

The report_progress tool is the only way to update an existing PR's description. The create_pull_request tool only works when no PR exists yet — it cannot edit the body of an existing PR.

Whenever you make meaningful progress on a task:

  1. Call report_progress with an accurate prDescription that follows .github/PULL_REQUEST_TEMPLATE.md.
  2. Use the exact top-level headings from the template: # Description, # Change Type, # Changelog. The CI labeler enforces a # Description section (single #) and will fail if ## headings are used or the section is missing.
  3. Populate every required section of the template (Description, Change Type, Changelog).
  4. Do not consider the task complete until the PR description has been updated via report_progress.

Important: The prDescription you pass to report_progress becomes the literal GitHub PR body. Always start it with # Description (not ## Description) so the CI labeler can find the required section.

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.
