From f052aa0fa4ccf71b68c124947fc9e6b7f0e8a0c0 Mon Sep 17 00:00:00 2001 From: Terada Kousuke Date: Mon, 6 Apr 2026 20:06:15 +0900 Subject: [PATCH 1/7] feat(guardrails): add multi-model delegation gates and quality/operational hooks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Delegation gates (OpenCode competitive advantage over Claude Code): - agent-model-mapping: tier-based model recommendation per agent type - delegation-budget-gate: hard block at 5 concurrent parallel tasks - cost-tracking: session-wide cost accumulation with threshold warning - parallel-execution-gate: prevents unbounded task delegation - verify-agent-output: detects empty/trivially short agent responses Quality hooks: - enforce-domain-naming: advisory for file naming convention mismatches - enforce-endpoint-dataflow: 4-point verification reminder on API changes - task-completion-gate: evidence verification before issue close - tool-failure-recovery: consecutive failure detection with recovery advice Operational hooks: - enforce-soak-time: merge timing advisory - enforce-follow-up-limit: feature freeze warning on 2+ consecutive fix PRs - enforce-issue-close-verification: acceptance criteria verification prompt - post-merge-close-issues: issue reference detection after merge -
