From 3f59a59d79d265ef896f6df8bf7e0e97296a2f9a Mon Sep 17 00:00:00 2001 From: Pranit Date: Sat, 29 Aug 2026 00:27:11 -0400 Subject: [PATCH 01/30] Unify command execution under shell Replace the terminal and background command surfaces with one managed shell lifecycle. Preserve process ownership, PTY input, output replay, legacy session cleanup, and Ctrl-X visibility through the existing runtime boundaries. --- sdk/AGENTS.md | 4 +- src/acp/prompt.zig | 52 +- src/acp/server.zig | 16 +- src/acp/sessions.zig | 53 +- src/acp/types.zig | 4 +- src/builtins/browser_workspace_tools.zig | 55 +- src/builtins/commands.zig | 25 +- src/builtins/context.zig | 429 -- src/builtins/tools.zig | 1290 ++--- src/core/agent/runtime/assistant_stream.zig | 4 +- src/core/agent/runtime/orchestrator.zig | 626 ++- src/core/agent/runtime/parallel_execution.zig | 2 +- src/core/agent/runtime/prompt_context.zig | 12 +- src/core/agent/runtime/stop_policy.zig | 190 -
