From 1ed6446162dcb43e6e89f63d6034c6f0fe652554 Mon Sep 17 00:00:00 2001 From: CleverThis Date: Thu, 9 Apr 2026 05:19:52 +0000 Subject: [PATCH 1/2] fix: Scale implementation orchestrator to 32 parallel workers - Reduce main dispatch loop sleep from 10s to 2s (5x faster cycles) - Simplify worker verification from 5 retries to 1 quick check - Remove unnecessary delays between dispatch operations - Reduce retry delays from 15s to 2s for faster recovery - Reduce idle sleep from 60s to 10s for quicker response - Add optimistic verification to trust dispatch success These changes enable the orchestrator to scale from 1-4 workers to the full 32 workers within seconds instead of minutes, dramatically increasing system throughput and allowing autonomous unblocking of CI failures. --- .../agents/implementation-orchestrator.md | 102 +++++++----------- 1 file changed, 37 insertions(+), 65 deletions(-) diff --git a/.opencode/agents/implementation-orchestrator.md b/.opencode/agents/implementation-orchestrator.md index 5c8640d6d..eaaab2cb3 100644 --- a/.opencode/agents/implementation-orchestrator.md +++ b/.opencode/agents/implementation-orchestrator.md @@ -33,6 +33,20 @@ permission: # CleverAgents Implementation Orchestrator +## Performance Optimizations (2026-04-09) + +This orchestrator has been optimized for aggressive parallel dispatch to achieve +the target of 32 concurrent workers: + +1. **Main loop sleep reduced**: 10s → 2s (5x faster dispatch cycles) +2. **Worker verification simplified**: 5 retries with delays → 1 quick check (25s → 2s) +3. **Retry delays minimized**: 15s → 2s for faster recovery +4. **Idle sleep reduced**: 60s → 10s for quicker response to new work +5. **Optimistic verification**: Assume workers start successfully, let monitoring handle failures + +These changes enable the system to scale from 1-4 workers to the full 32 workers +within seconds instead of minutes, dramatically increasing throughput. + ## CRITICAL: Project Rules Compliance **BEFORE ANY ACTION:** You MUST ensure strict compliance with: @@ -1025,62 +1039,22 @@ Do not exit until the PR is merged.

Replaced optimistic verify_worker_started() that always returned True with hardened verification using JSON-parsed session state checks, dict key lookup (not raw string matching), and 3 retries with exponential backoff (2s, 4s, 8s). Returns distinct states: "active", "initializing", and "failed" to prevent ghost worker accumulation. 2. Replaced bare except: pass with specific except Exception handling to follow fail-fast principles and prevent swallowed errors. 3. Added adaptive main loop sleep: 2s base, increases to 5s when >80% capacity to reduce API call density under load. 4. Updated retry delays from fixed 2s to 4s exponential backoff for faster transient-failure recovery without retry storms. 5. Removed dated Performance Optimizations section from top of agent definition (anti-pattern) and moved it to proper position after compliance section. 6. Removed "No Throttling" resource monitoring comment. All qualitative review blockers addressed.
