Hi @VolkovIlia, thanks for the report and the self-fix!

Original issue: agent: "gh" refers to the GitHub CLI (gh), which is NOT an ACP-compatible agent. The ACP provider expects an agent that speaks the Agent Client Protocol — like claude, codex, or copilot. The gh CLI outputs its help text as plain text, which acpx tries to parse as JSON, causing the cascade of errors you saw.

Your fix is correct: Changing to agent: "copilot" (GitHub Copilot CLI) resolves this.

Regarding the Stage 10 GitHub API 404 errors: These https://api.github.com/search/code 404 errors are typically caused by GitHub API rate limiting or authentication issues. The code search API requires authentication. This is non-critical — the pipeline falls back to other code generation approaches when GitHub search is unavailable.

We'll update the documentation to clarify which agents are ACP-compatible.
