Agents were guessing absolute paths for file/exec tools, causing failed
tool calls and wasteful retries. Strengthen LLM guidance at three levels:
- System prompt: instruct to use relative paths, not guess absolute paths
- Tool param descriptions: mention workspace-relative resolution
- Subagent prompt: add missing workspace section with path guidance
Four per-agent settings stored in the database (and configurable via UI)
were silently ignored at runtime because the tool/system layer always
used the global config defaults instead.
**restrict_to_workspace**: Tools used the global config default baked at
startup. Fix: pass per-agent value through context; tools check context
override before falling back to constructor default.
**subagents_config**: ParseSubagentsConfig() existed but was never called.
All agents shared one SubagentManager with global limits. Fix: resolve
per-agent config in the agent resolver, store it on each spawned task,
and use it for limit checks, deny lists, and system prompt generation.
**memory_config**: Only the enabled toggle was read per-agent; search
weights (vector_weight, text_weight, max_results, min_score) were
hardcoded from PGMemoryStore defaults. Fix: extend MemorySearchOptions
with weight overrides, read per-agent config from context in the
memory_search tool.
**sandbox_config**: Only workspace_access was extracted per-agent; mode,
image, memory, CPU, timeout, network settings were discarded. Fix: pass
full sandbox.Config through context; Manager.Get() accepts an optional
config override for new containers.
