# Dependencies Review Report

**Branch**: feat/simplify-event-system-88 -> main
**Date**: 2026-03-16
**PR**: #91

## Issues in Your Changes (BLOCKING)

No blocking dependency issues found.

## Issues in Code You Touched (Should Fix)

No should-fix dependency issues found.

## Pre-existing Issues (Not Blocking)

### LOW
**Stale documentation reference to deleted module** - `tests/TESTING_ARCHITECTURE.md:46`
- Problem: `TESTING_ARCHITECTURE.md` still references `autoscaling-manager.test.ts` in the file tree, but this test file was deleted in this PR.
- Impact: Documentation drift; no runtime impact.
- Fix: Remove the line referencing `autoscaling-manager.test.ts` from the testing architecture doc. Not blocking since the file is documentation, not code.

## Analysis Details

### Dependency Changes: None

The `dependencies` and `devDependencies` sections in `package.json` are **identical** between `main` and this branch. No packages were added or removed.

| Dependency | Version (main) | Version (branch) | Change |
|-----------|----------------|-------------------|--------|
| @clack/prompts | ^1.0.1 | ^1.0.1 | None |
| @modelcontextprotocol/sdk | ^1.24.3 | ^1.24.3 | None |
| better-sqlite3 | ^12.4.1 | ^12.4.1 | None |
| cron-parser | ^4.9.0 | ^4.9.0 | None |
| zod | ^3.25.76 | ^3.25.76 | None |

All devDependencies are also unchanged.

### package.json Script Changes

Two test scripts were modified to remove references to deleted test files:

1. **`test:services`** - Removed `autoscaling-manager.test.ts` (file deleted)
2. **`test:handlers`** - Removed `query-handler.test.ts` and `output-handler.test.ts` (files deleted)

These changes are correct and consistent with the deleted source/test files.

### Lockfile Status

- `package-lock.json` exists and is tracked by git.
- No lockfile modifications in this PR (expected, since no dependency changes).

### Deleted Modules and Import Cleanup

Three source modules and their corresponding test files were deleted:

| Deleted Source File | Deleted Test File |
|--------------------|-------------------|
| `src/services/autoscaling-manager.ts` | `tests/unit/services/autoscaling-manager.test.ts` |
| `src/services/handlers/output-handler.ts` | `tests/unit/services/handlers/output-handler.test.ts` |
| `src/services/handlers/query-handler.ts` | `tests/unit/services/handlers/query-handler.test.ts` |

**Import cleanup verified**: Zero remaining references to `AutoscalingManager`, `QueryHandler`, or `OutputHandler` in the `src/` directory. Two benign comment references in test files (explaining what mocks replace) are acceptable.

### Dependency Usage Audit (Post-Deletion)

All 5 production dependencies remain actively used after the deletions:

| Dependency | Used In |
|-----------|---------|
| @clack/prompts | `src/cli/ui.ts`, `src/cli/commands/init.ts` |
| @modelcontextprotocol/sdk | `src/index.ts`, `src/adapters/mcp-adapter.ts` |
| better-sqlite3 | 6 repository/database implementation files |
| cron-parser | `src/utils/cron.ts` |
| zod | 6 files (adapters, config, repositories) |

No orphaned dependencies were introduced by the removal of the autoscaling manager, query handler, or output handler.

### Supply Chain Assessment

- No new packages introduced (zero attack surface change)
- No version range changes
- Lockfile committed and unchanged
- Package removal reduces code surface area (net positive for security)

## Summary

| Category | CRITICAL | HIGH | MEDIUM | LOW |
|----------|----------|------|--------|-----|
| Blocking | 0 | 0 | 0 | - |
| Should Fix | - | 0 | 0 | - |
| Pre-existing | - | - | 0 | 1 |

**Dependencies Score**: 10/10
**Recommendation**: APPROVED

This PR makes no dependency changes. The only `package.json` modifications are removing deleted test files from test scripts, which is correct housekeeping. All production dependencies remain actively used. The deletion of 3 source modules and their tests reduces the project's internal dependency graph without affecting external packages.
