Address issues identified in PR #137 with a cleaner approach:
- Sandbox isolation: add SandboxCwd/ResolveSandboxPath helpers to map
filesystem tool paths to agent-scoped container subdirectories,
preventing cross-agent file access via read/write/edit/list tools
- DooD volume mounting: add resolveHostWorkspacePath with multi-strategy
container ID detection (/proc/self/mountinfo, HOSTNAME, os.Hostname)
and 5s timeout on docker inspect
- Sandbox hints: expand from 1 pattern (binary not found) to 6 patterns
(permission denied, network disabled, read-only FS, missing file,
resource limits) with MaybeFsBridgeHint for filesystem tools
- Nginx DNS: add Docker resolver (127.0.0.11) with dynamic upstream
variable to handle backend container IP changes
- MCP args: switch from comma-separated to space-separated parsing
with quote support for --flag="value with spaces" patterns
- Refactor: rename ExecTool.workingDir to workspace for consistency,
extract sandbox.DefaultContainerWorkdir constant
* fix(memory): auto-backup + overwrite warning for memory files
When an agent writes to a memory file that already has content:
1. Old content is backed up to memory/.prev/{filename} (best-effort)
2. Write succeeds normally (no blocking)
3. Tool result includes warning with previous content (truncated to
4000 chars) so the agent can notice and merge if needed
Backup files are hidden from list_files and not indexed/embedded.
No database migration needed - uses existing PutDocument.
* fix(memory): support append mode + fix UTF-8 truncation in overwrite warning
- Add appendMode parameter to MemoryInterceptor.WriteFile() so
write_file(append=true) actually appends to memory files instead
of silently replacing content. Uses "\n\n---\n\n" separator.
- Fix UTF-8 truncation in overwrite warning: use []rune instead of
byte slicing to avoid cutting multi-byte characters.
- Fix char count in warning message: use len([]rune()) not len().
- Remove .prev/ backup mechanism (prevBackupPath, isPrevPath, backup
writes, ListFiles filter) in favor of simpler approach: append
mode prevents data loss, warning enables self-correction.

- Add append=true parameter for chunked file writing
- Add ~12000 char warning in tool description and system prompt
- Helps models avoid API truncation on large file writes
Flip write_file deliver param default from false to true so result files
(reports, articles, generated content) are automatically sent as document
attachments to chat channels without requiring explicit LLM opt-in.
Add .md MIME type to mimeFromExt for proper markdown file delivery.
- Add WithToolTeamWorkspace/ToolTeamWorkspaceFromCtx context key for
team workspace path (accessible but not necessarily default)
- Create WorkspaceInterceptor for team-specific write validation
(RBAC, quota, blocked extensions, event broadcasting)
- File tools (read_file, write_file, list_files, edit) allow access
to team workspace via allowedWithTeamWorkspace() helper
- read_file/list_files hint team workspace path when file not found
- Registry detects empty tool call args and returns actionable hint
(DashScope/Qwen large-output truncation workaround)
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.
