From 983af5e14f1a0b2ed88fce0bb8fbba7bc5703571 Mon Sep 17 00:00:00 2001 From: leynos Date: Thu, 9 Apr 2026 18:27:57 +0200 Subject: [PATCH 01/36] refactor(agent): split delegate.rs into cohesive submodules (fixes #122) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Split src/agent/dispatcher/delegate.rs into a module directory to address CodeScene warnings: - Complex Method: execute_tool_calls (CC = 47) - Low Cohesion: 5 distinct responsibilities New structure: src/agent/dispatcher/delegate/ ├── mod.rs # ChatDelegate struct, thin NativeLoopDelegate impl ├── llm_hooks.rs # check_signals, before_llm_call, call_llm, handle_text_response │ # + compact_messages_for_retry, strip_internal_tool_call_text └── tool_exec.rs # Slimmed execute_tool_calls (orchestration only) # + All helper methods extracted from original: # - record_redacted_tool_calls # - group_tool_calls (PreflightOutcome, ToolBatch) # - run_tool_batch_inline, run_tool_batch_parallel # - handle_rejected_tool # - process_runnable_tool (returns Option for auth) # - maybe_emit_image_sentinel # - sanitize_output # - fold_into_context # + execute_chat_tool_standalone # + check_auth_required, parse_auth_result, ParsedAuthData execute_tool_calls now only orchestrates: 1. Push assistant message with tool calls 2. Send "Thinking / executing N tool(s)..." status 3. Call record_redacted_tool_calls 4. Call group_tool_calls → destructure ToolBatch 5. Dispatch to inline or parallel execution 6. Post-flight loop calling handle_rejected_tool or process_runnable_tool 7. Return deferred-auth or NeedApproval outcome Also consolidated preflight.rs, execution.rs, postflight.rs into delegate/ to eliminate module fragmentation. All 3575 tests pass. No observable behavior changed.

Large error payloads (verbose shell/HTTP failures) could inflate persisted conversation rows and increase token pressure on rehydrated context. Apply the same truncate_preview(1000) strategy used for results.

Trim the now-unreachable legacy delegate helpers, keep approval-test coverage intact, and add a regression test proving the assistant tool-call message records the post-hook arguments rather than the original payload. --- src/agent/dispatcher/delegate/loops.rs | 177 +----------- src/agent/dispatcher/delegate/mod.rs | 56 +++- src/agent/dispatcher/delegate/preflight.rs | 218 +-------------- .../dispatcher/delegate/tool_exec/mod.rs | 259 ++++++++++++++++-- .../delegate/tool_exec/postflight.rs | 16 +- src/agent/dispatcher/types.rs | 27 -- 6 files changed, 287 insertions(+), 466 deletions(-) diff --git a/src/agent/dispatcher/delegate/loops.rs b/src/agent/dispatcher/delegate/loops.rs index e684c9b6b..3297a8dbe 100644 --- a/src/agent/dispatcher/delegate/loops.rs +++ b/src/agent/dispatcher/delegate/loops.rs @@ -8,131 +8,9 @@ use crate::agent::session::ThreadState;
