Add complete pt-BR translation of the README and update language
navigation links across all existing READMEs (English, Chinese,
Japanese) to include the Portuguese option.
Phase 1: centralize protocol message/tool/response types in protocoltypes and keep compatibility aliases in providers and protocol packages.
Phase 1: preserve HTTPProvider constructor compatibility and route Anthropic api_base through factory auth/provider constructors with base URL normalization.
Phase 2: expand provider routing/auth tests (deepseek/nvidia/shengsuanyun, codex/claude oauth/codex-cli) and add openai_compat + anthropic coverage for proxy transport, model normalization, numeric option coercion, token-source refresh, and base URL behavior.
Phase 3: apply gofmt and validate with Dockerized tests (go test ./pkg/providers/... ./pkg/migrate and go test ./...).
Replace unconditional WithTimeout usage with conditional context creation
based on timeout configuration. Zero values now bypass timeout enforcement,
using WithCancel for graceful cancellation while preserving existing timeout
behavior for positive values. Simplifies CronTool initialization by removing
unnecessary conditional timeout assignment.
Remove pre-populated example servers (filesystem, github, brave-search,
postgres) from DefaultConfig() to reduce memory footprint per instance.
Changes:
- Set MCP.Servers to empty map instead of 4 example servers
- Reduces default config size by ~500 bytes per instance
- Users should add MCP servers via config.json or documentation
Example configurations are still available in:
- README.md MCP section
- config.example.json
- Official MCP documentation
This optimization benefits deployments with many agent instances.
Replace full *config.Config reference with config.MCPConfig value type
in AgentLoop to allow garbage collection of unused configuration data.
Changes:
- AgentLoop now stores only MCPConfig and workspacePath (minimal deps)
- Add mcp.Manager.LoadFromMCPConfig() for minimal dependency version
- Keep LoadFromConfig() for backward compatibility
- Full Config object can be GC'd after NewAgentLoop() returns
This optimization reduces memory usage by not holding references to
unused channel, provider, gateway, and device configurations.
Resolve conflicts:
- pkg/agent/loop.go: integrate context compression, command handling,
utf8 token estimation, and summarization notification into
multi-agent routing architecture
- pkg/config/config_test.go: merge imports from both branches
- pkg/agent/loop_test.go: update test to use registry-based sessions
Critical bug fix:
- MCP tools were never registered because servers loaded in Run()
but tool registration happened in NewAgentLoop() with empty manager
- Move MCP tool registration from createToolRegistry to Run()
- Register MCP tools for both main agent and subag after successful server loading
- Add subagentManager field to AgentLoop for dynamic registration
- Add tool_count logging for better observability
This ensures MCP tools are properly available to both agent and subagents.
- Add defer in Run() to guarantee MCP connection cleanup
- Handles both normal termination and context cancellation
- Prevents resource leaks when Run() exits via ctx.Done()
- MCP Manager.Close() is idempotent, safe to call from both defer and Stop()
This fixes GitHub Copilot feedback that MCP cleanup only happened in
Stop() but Run() could return on ctx.Done() without cleanup, causing
subprocess/session leaks on normal cancellation shutdown.
- Defer MCP server initialization to Run() using agent's context
- Add mcpConfig and mcpInitOnce fields to AgentLoop
- Use sync.Once to ensure MCP loads exactly once with proper context
- Prevents orphaned subprocesses and resource leaks on cancellation
This fixes GitHub Copilot feedback that MCP connections with
context.Background() won't terminate when the agent stops, causing
potential resource leaks and orphaned stdio/SSE connections.
- Handle json.RawMessage and []byte types by direct unmarshal
- Use JSON marshal/unmarshal for struct types to preserve schema
- Add test case for json.RawMessage schema
- Fixes issue where non-map schemas returned empty object
This fixes GitHub Copilot feedback that Parameters() was dropping
tool schema when InputSchema wasn't already map[string]interface{}
- Change NewMCPTool to accept MCPManager interface instead of concrete *mcp.Manager
- Remove unused mcpPkg import from mcp_tool.go
- Remove newMCPToolForTest helper function as NewMCPTool now accepts interface
- Update all tests to use NewMCPTool directly with MockMCPManager
- Improves testability and follows dependency inversion principle
- Resolve relative envFile paths relative to workspace instead of CWD
- Add filepath import for path operations
- Pass workspace path to goroutines for path resolution
- Improves portability in Docker environments where CWD may vary
- Absolute envFile paths continue to work as before
- Add errors.Join to return aggregated error when all enabled MCP servers fail
- Track enabled server count separately from total configured servers
- Return error only when all servers fail, not for partial failures
- Improve logging with accurate server counts (enabled vs connected)
- Maintains fault tolerance: partial failures don't stop initialization
