From f41389edfc8d6ed73e889959043438ee34421e60 Mon Sep 17 00:00:00 2001 From: Clifford Ressel Date: Tue, 2 Dec 2025 14:53:30 -0500 Subject: [PATCH 1/5] feat(acp): Add approval bridging infrastructure Implements the minimal-footprint approval bridging between ACP permission requests and Codex approval system: - Add ApprovalRequest type bundling translated event with response channel - Translate ACP RequestPermissionRequest to Codex ExecApprovalRequestEvent - Translate Codex ReviewDecision back to ACP RequestPermissionOutcome - Expose approval receiver via AcpConnection::take_approval_receiver() - Fall back to auto-approve if channel closed, deny if response dropped - Add placeholder comments for future: history persistence, export, resume This enables the TUI to receive approval requests and respond to them without modifying codex-core. --- codex-rs/acp/DESIGN_DECISIONS.md | 248 ++++++++++++++++++ codex-rs/acp/DESIGN_SUMMARY.md | 18 ++ codex-rs/acp/docs.md | 51 +++- codex-rs/acp/src/connection.rs | 161 ++++++++++-- codex-rs/acp/src/lib.rs | 1 + codex-rs/acp/src/translator.rs | 214 +++++++++++++++ .../streaming__cancelled_stream.snap | 2 +- .../snapshots/streaming__submit_input.snap | 2 +- 8 files changed, 679 insertions(+), 18 deletions(-) create mode 100644 codex-rs/acp/DESIGN_DECISIONS.md create mode 100644 codex-rs/acp/DESIGN_SUMMARY.md diff --git a/codex-rs/acp/DESIGN_DECISIONS.md b/codex-rs/acp/DESIGN_DECISIONS.md new file mode 100644 index 000000000..c2dbfef1f --- /dev/null +++ b/codex-rs/acp/DESIGN_DECISIONS.md @@ -0,0 +1,248 @@ +# ACP Integration: Critical Design Decisions + +## Core Principle: Minimal Footprint + +The ACP implementation is designed to **minimize changes to codex-core** to ease the burden of accepting upstream changes.

This made tests non-deterministic. Changes: - Add normalize_for_input_snapshot() function that strips the startup header block (both boxed and plain text forms) for consistent snapshots - Update all E2E tests to use the new normalization function - Regenerate all snapshots without header content for determinism - Keep original normalize_for_snapshot() for cases where header content needs to be tested explicitly The header is detected by looking for box characters, To get started, or Welcome to Codex, then stripping everything up to and including the /review command line. --- codex-rs/acp/src/translator.rs | 13 +- codex-rs/tui-pty-e2e/docs.md | 29 +-- codex-rs/tui-pty-e2e/src/lib.rs | 46 +++++ codex-rs/tui-pty-e2e/tests/acp_mode.rs | 174 ++++++++++++++++++ codex-rs/tui-pty-e2e/tests/input_handling.rs | 8 +- codex-rs/tui-pty-e2e/tests/prompt_flow.rs | 10 +- .../snapshots/acp_mode__acp_mode_startup.snap | 7 + .../prompt_flow__custom_response.snap | 11 +- .../prompt_flow__prompt_submitted.snap | 11 +- .../startup__runs_in_temp_directory.snap | 18 +- .../startup__startup_shows_welcome.snap | 3 +- ...up__startup_welcome_dimensions_40x120.snap | 18 +- .../streaming__cancelled_stream.snap | 16 +- .../snapshots/streaming__submit_input.snap | 17 +- codex-rs/tui-pty-e2e/tests/startup.rs | 10 +- codex-rs/tui-pty-e2e/tests/streaming.rs | 6 +- 16 files changed, 274 insertions(+), 123 deletions(-) create mode 100644 codex-rs/tui-pty-e2e/tests/acp_mode.rs create mode 100644 codex-rs/tui-pty-e2e/tests/snapshots/acp_mode__acp_mode_startup.snap diff --git a/codex-rs/acp/src/translator.rs b/codex-rs/acp/src/translator.rs index a2ce71914..e3dde14a5 100644 --- a/codex-rs/acp/src/translator.rs +++ b/codex-rs/acp/src/translator.rs @@ -180,9 +180,10 @@ fn extract_command_from_tool_call(tool_call: &acp::ToolCallUpdate) -> Vec Vec Option { // Use the title as a basic description, or fall back to ID - let name = tool_call - .fields - .title - .as_deref() - .unwrap_or("unknown tool");
