Sub-agents configured under [agents.<name>] previously received only the
bare system_prompt string. They now receive a structured system prompt
containing: tools section (allowed tools with parameters and invocation
protocol), skills section (from scoped or default directory), workspace
path, current date/time, safety constraints, and shell policy when shell
is in the effective tool list.
Add optional skills_directory field to DelegateAgentConfig for per-agent
scoped skill loading. When unset, falls back to default workspace
skills/ directory.
Closes#3046
