Copilot

An adapter that starts the GitHub Copilot command-line program through ACP, a standard protocol for communicating with coding agents. It uses Copilot's standard-input mode so acpx can exchange messages with it.

In plain words
What is it for?
Use it to launch GitHub Copilot CLI through acpx. Your installed Copilot version must support ACP over standard input.
Why use it?
It provides a direct acpx entry point for Copilot CLI sessions. It also makes the version requirement clear, because older Copilot CLI releases cannot start in the required ACP mode.

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 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.

What it actually says

Copilot

acpx copilot requires a GitHub Copilot CLI release that supports ACP stdio mode. Older copilot binaries fail before ACP startup.

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.

Copilot is an agent published in the GitHub repository openclaw/acpx (3,194 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 85 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
