* fix(harness): allow agent read access to /mnt/skills in local sandbox Skill files under /mnt/skills/ were blocked by the path validator, preventing agents from reading skill definitions. This change: - Refactors `resolve_local_tool_path` into `validate_local_tool_path`, a pure security gate that no longer resolves paths (left to the sandbox) - Permits read-only access to the skills container path (/mnt/skills by default, configurable via config.skills.container_path) - Blocks write access to skills paths (PermissionError) - Allows /mnt/skills in bash command path validation - Adds `LocalSandbox.update_path_mappings` and injects per-thread user-data mappings into the sandbox so all virtual-path resolution is handled uniformly by the sandbox layer - Covers all new behaviour with tests Fixes #1177 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * refactor(sandbox): unify all virtual path resolution in tools.py Move skills path resolution from LocalSandbox into tools.py so that all virtual-to-host path translation (user-data and skills) lives in one layer. LocalSandbox becomes a pure execution layer that receives only real host paths — no more path_mappings, _resolve_path, or reverse resolve logic. This addresses architecture feedback that path resolution was split across two layers (tools.py for user-data, LocalSandbox for skills), making the flow hard to follow. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(sandbox): address Copilot review — cache-on-success and error path masking - Replace @lru_cache with manual cache-on-success for _get_skills_container_path and _get_skills_host_path so transient failures at startup don't permanently disable skills access. - Add _sanitize_error() helper that masks host filesystem paths in error messages via mask_local_paths_in_output before returning them to the agent. - Apply _sanitize_error() to all catch-all (Exception/OSError) handlers in sandbox tool functions to prevent host path leakage in error output. - Remove unused lru_cache import.
