In `@internal/mail/mailbox_test.go`:
- Around line 438-448: Add a new table-driven test TestSafePath_EdgeCases that
calls safePath with a variety of problematic filenames and asserts it returns
ErrInvalidPath for invalid inputs; include cases for empty string, bare "..", a
filename containing a null byte, and backslash-based traversal (e.g.,
"..\\etc\\passwd"), and use t.Run subtests to make failures clear while
comparing errors to ErrInvalidPath. Ensure the test imports/uses the same error
identifier ErrInvalidPath and reuses the same base directory string as in
TestSafePath_DotInFilename so behavior is consistent.

5-5: The GitHub Actions CI/CD pipeline is fully implemented and operational.PR testing (test.yml) runs on pull requests and main branch pushes with comprehensive checks including formatting, dependency verification, unit tests with coverage reporting, and security scanning (govulncheck and gosec). Release creation (release.yml) is configured with semantic versioning using paulhatch/semantic-version, automatically calculating version numbers from commit messages. Multi-platform binary distribution is implemented via a build matrix that compiles for linux-amd64, linux-arm64, darwin-amd64, and darwin-arm64, with artifacts included in GitHub releases. The Homebrew tap is automatically updated upon release. All workflows include proper concurrency controls, timeouts, and error handling.

5-5: Confirm the storage restructure feature is fully implemented and tested.The status update to "Implemented" is accurate. Verification of the codebase confirms that all 15 functional requirements (FR-001 through FR-015) and all 6 success criteria (SC-001 through SC-006) are implemented and extensively tested:
Key findings:
- ✓
.agentmail/and.agentmail/mailboxes/directories are consistently used throughout the codebase with proper constants (RootDir = ".agentmail",MailDir = ".agentmail/mailboxes")- ✓ Messages are stored in
.agentmail/mailboxes/<recipient>.jsonlwith JSONL format maintained- ✓ Recipient state stored at
.agentmail/recipients.jsonlwith proper read/write handling- ✓ Daemon PID file location updated to
.agentmail/mailman.pid(PIDFile constant and PIDFilePath function verified)- ✓ No references to deprecated
.git/mail/or.git/mail-recipients.jsonlfound in codebase- ✓ Directory creation with appropriate permissions (0750 for directories) implemented in EnsureMailDir and tested
- ✓ File watching infrastructure (FileWatcher class) properly configured to monitor
.agentmail/hierarchy- ✓ Comprehensive test coverage across all affected modules (mailbox, recipients, daemon, CLI, MCP handlers)
- ✓ Git repository requirement maintained; silent transition from old storage location confirmed
All functional and success criteria are met.

5-5: Claude hooks integration is fully implemented and properly tested.The
--hookflag functionality is complete:
- FR-001: Outputs "You got new mail" to STDERR with message details and exits with code 2 when unread messages exist
- FR-002: Exits silently (code 0, no output) when no unread messages exist
- FR-003: Exits silently (code 0, no output) when not in a tmux session
- FR-004: All error conditions (file read, lock, corruption) exit silently with code 0
- FR-005: All output is written to STDERR in hook mode
- FR-006: Documentation is comprehensive in the README under "Claude Code Hooks" section with configuration instructions and behavior explanation
Implementation verified in
internal/cli/receive.go(lines 22-176), with test coverage for all scenarios ininternal/cli/receive_test.go.specs/010-mcp-server/spec.md (1)
5-5: MCP server implementation is fully complete and ready.All requirements are implemented and tested:
- STDIO transport (FR-001) ✓
- Four tools with descriptions and schemas (FR-002, FR-011) ✓
- Send/receive/status/list-recipients handlers (FR-003–FR-009) ✓
- Message size validation at 64KB (FR-013) ✓
- Tmux context monitoring with 1-second exit on loss (FR-014) ✓
- Error handling and logging (FR-010, FR-015, FR-016) ✓
- Comprehensive test coverage (3493 lines across handlers, server, and tools tests) ✓

5-5: Formula file not found - status "Implemented" appears premature.The Homebrew tap repository
UserAd/homebrew-agentmailexists and is properly set up, but the required formula file is not accessible athttps://raw.githubusercontent.com/UserAd/homebrew-agentmail/main/agentmail.rb(returns 404). According to the specification (FR-001), the formula is a mandatory requirement for this feature to be functional. The status should remain "Draft" or "In Progress" until the formula file is pushed to the tap repository.specs/008-stale-agent-mailman/spec.md (1)
5-5: Implementation confirmed - The status change to "Implemented" is justified.Evidence of implementation found across the codebase:
- Stale agent tracking via
StatelessTrackerininternal/daemon/loop.go- Notification loop with stale agent processing (T020-T024)
- Mailman daemon with file watcher for instant notifications
- Recipients command (
list-recipientstool).agentmailignorefile support ininternal/mail/internal/mail/mailbox_test.go (4)
371-383: Well-structured security test introduction.Good use of a clear comment header and a straightforward test case for the valid filename scenario. The test properly validates both the error return and the expected path result.
385-406: Comprehensive directory traversal test coverage.Excellent use of table-driven tests covering multiple traversal attack vectors including the subtle "hidden traversal" case (
foo/../../../etc/passwd) that attempts to bypass naive prefix checks. The test cases align well with OWASP path traversal attack patterns.
427-436: Good coverage of valid subdirectory paths.This test ensures the security function doesn't over-restrict, allowing legitimate nested directory structures while still protecting against traversal attacks.
408-425: Remove the suggestion to add Windows path tests—this project is Unix/Linux/macOS only.The codebase uses
syscall.Flock()for file locking andtmuxfor window management, both of which are Unix-only. CI is configured to test on Linux only and build releases for Linux and macOS only—no Windows support is planned. The existing Unix absolute path tests are sufficient for the project's scope.Likely an incorrect or invalid review comment.

🧹 Nitpick | 🔵 Trivial
Good dot normalization test; consider additional edge cases.
The test correctly validates that ./ is cleaned. For comprehensive security coverage, consider adding tests for additional edge cases.
🛡️ Suggested additional edge case tests
func TestSafePath_EdgeCases(t *testing.T) {
tests := []struct {
name string
filename string
expectErr bool
}{
{"empty filename", "", true},
{"only dots", "..", true},
{"null byte injection", "file\x00.jsonl", true},
{"backslash traversal", "..\\etc\\passwd", true},
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
_, err := safePath("/base/dir", tt.filename)
if tt.expectErr && err != ErrInvalidPath {
t.Errorf("safePath should reject %q with ErrInvalidPath, got: %v", tt.filename, err)
}
})
}
}These cases cover:
- Empty filenames (could cause unexpected behavior)
- Bare
..without slash - Null byte injection (classic attack to truncate paths in some systems)
- Backslash-based traversal (relevant if paths are passed through different systems)

Core AgentMail structure is NOT fully implemented per specification constraints.
While send and receive commands (FR-001 through FR-012) are implemented with JSONL-based message storage and tmux integration, the following specification requirements are not met:
- IC-002 (stdlib only): Implementation uses external dependencies (fsnotify, modelcontextprotocol/go-sdk, ff/v3), violating the stdlib-only constraint.
- SC-005 (80% test coverage): Current test coverage is below 80% target across multiple packages:
- internal/cli: 68.3%
- internal/mail: 72.9%
- internal/tmux: 46.7%
IC-001 (Go 1.21+) is satisfied with go 1.25.5.
