* feat(node-vfs): enhance VfsSandbox to support absolute paths in commands and add related integration tests
- Implemented a method to rewrite absolute paths in commands referencing VFS entries to point to the temporary directory.
- Added integration tests for executing multi-file Node.js projects with both absolute and relative paths.
- Updated existing tests to clarify path usage in commands.

* fix(deepagents): reorder middleware so prompt caching and memory run last
Move anthropicPromptCachingMiddleware and memoryMiddleware after all static

* feat(acp): add authMethods to InitializeResponse for ACP registry compliance
The ACP registry CI verifies that agents advertise authentication
methods during initialization. Add configurable `authMethods` to
`DeepAgentsServerOptions` with sensible defaults (Anthropic/OpenAI
env_var methods + agent-type fallback), and expose typed interfaces
for all three ACP auth method types (agent, env_var, terminal).

* test isAnthropicModel
* update logic to ensure all stable content BEFORE the memory block is cached - not just the system prompt
* fix type check error
* add cache breakpoint after subagent middleware for default and general purpose
* fix: delegate CompositeBackend.id to default sandbox backend
CompositeBackend failed isSandboxBackend check because it lacked the
required id property from SandboxBackendProtocol. Added a get id()
getter that delegates to the default backend's id when it is a sandbox,
or returns an empty string otherwise. This preserves the real sandbox
ID (e.g. from Daytona/Deno/Modal) for external lifecycle operations
like provider.delete({ sandboxId: sandbox.id }).
Fixes#275
* Fix delegation of CompositeBackend.id to sandbox backend
* fix: add truncation to grep/glob/ls tool results
Fixes#272
grep, glob, and ls tools can return hundreds of KB of results, which
can exceed context limits and cause model retries or blank responses.
This adds truncation at the TOOL_RESULT_TOKEN_LIMIT (20K tokens ~80KB)
threshold, consistent with read_file's existing behavior.
Changes:
- Import truncateIfTooLong utility in fs.ts middleware
- Apply truncation to ls, glob, and grep tool results
- Truncate arrays before joining to preserve complete lines
- Add guidance message when results are truncated
The truncation happens in the middleware layer (matching Python's
architecture), not in the backend, so backends return full results
and middleware applies the limit.
* test: add documentation for truncation test coverage
Add note explaining that ls/grep/glob truncation is covered by
existing truncateIfTooLong tests in utils.test.ts (lines 290-314).
Full integration tests would require complex LangGraph context setup.
* test: add integration tests for ls/grep/glob truncation
Add proper integration tests that verify truncation works through the
entire middleware → tool → backend → formatting → truncation pipeline.
- Mock getCurrentTaskInput to enable tool invocation without LangGraph
- Test ls, glob, and grep tools with large result sets (truncated)
- Test ls, glob, and grep tools with small result sets (not truncated)
- Remove unnecessary comments for cleaner test code
These tests verify that the truncation logic added in commit 6e4a2b8
works correctly through the full middleware integration.
* Implement truncation in tool results
Add truncation feature to grep, glob, and ls tool results.
