feat(hooks): add single-task directive and system-reminder tags to orchestrator

code-yeongyu · sisyphus-dev-ai · code-yeongyu · commit 5331a9f8c18a · 2026-01-08T23:07:05.000+09:00
Inject SINGLE_TASK_DIRECTIVE when orchestrator calls sisyphus_task to enforce atomic task delegation. Wrap verification reminders in <system-reminder> tags for better LLM attention. Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-opencode) Co-authored-by: Sisyphus <clio-agent@sisyphuslabs.ai>
