37-41: LGTM!

The addition of Monaco editor schema files to the ASAR unpack list is appropriate. Monaco needs direct filesystem access to these files, and unpacking them ensures they're available at runtime.

84-102: Excellent fix for stale closure in keepalive interval.

The ref pattern correctly ensures the interval always accesses the latest parts array. Without this, the interval would capture stale parts from when the effect first ran, causing keepalive calls to reference outdated tool call IDs if parts changed.

Removing parts from the dependency array is correct since the ref provides access to current values without triggering effect recreation.

---

236-256: Consistent application of the ref pattern for keepalive stability.

The toolCallIdRef follows the same pattern as partsRef in AIToolUseBatch, ensuring the keepalive interval references the current tool call ID even if toolData.toolcallid changes between renders.

---

406-416: Clearer batch insertion logic.

The restructured if-else chain ensures each batch type (approval-needed vs. no-approval) is inserted exactly once when the first matching part is encountered, preventing duplicate batch insertions. The explicit flag checks (addedApprovalBatch, addedOtherBatch) make the single-insertion guarantee clear.

55-76: Well-implemented input verification hook.

The verification function provides early validation before tool execution:

1. Parses and validates input parameters
2. Expands home directory paths
3. Confirms the path exists via os.Stat
4. Enforces that the path is a directory

The directory check at lines 71-73 prevents tool misuse by guiding users to use read_text_file for files instead.

Note: There's a small TOCTOU window between verification and execution where the path could be deleted or changed, but this is acceptable for this use case.

---

157-157: Verification hook properly integrated.

The ToolVerifyInput assignment ensures inputs are validated before the tool callback executes, providing better error messages and preventing unnecessary work.

pkg/aiusechat/tools_readfile.go (2)

200-225: Robust input verification with security checks.

The verification function implements defense-in-depth validation:

1. Input parsing and validation
2. Path expansion with home directory support
3. Security check: Blocks access to sensitive files (credentials, keys, etc.) early
4. Path existence verification
5. Type check to prevent directory reads

The early sensitive file check at lines 211-213 is particularly valuable—it prevents unnecessary I/O and provides immediate feedback when users attempt to access blocked files.

Note: As with verifyReadDirInput, there's a minor TOCTOU window between verification and execution, which is acceptable here.

---

400-400: Verification hook properly integrated.

Consistent with the pattern in tools_readdir.go, the ToolVerifyInput assignment enables early validation and better error reporting.
