Code Review
This pull request aims to deliver critical security and stability fixes, specifically addressing a SQL injection vulnerability and resolving a resource leak in concurrent request handling. While it correctly identifies and fixes a SQL injection in the get_top_models method and addresses thread-safety, the SQL injection fix in src/heidi_cli/integrations/analytics.py is incomplete, as it missed several other methods using the same vulnerable pattern. Additionally, the PR introduces a new HeidiDoctor code health checker. While potentially useful, its inclusion expands the scope of this critical fix PR and introduces issues such as unused imports, a critical missing dependency causing runtime crashes, and flawed import analysis logic. It is recommended to move the HeidiDoctor feature to a separate pull request to allow these important fixes to be merged promptly.

src/heidi_cli/doctor/doctor.py (116)
This line imports the toml package, but it is not declared as a dependency in pyproject.toml. This will cause a ModuleNotFoundError at runtime for users who don't have it installed. Please add toml to the project's dependencies to ensure this new feature works correctly.
src/heidi_cli/integrations/analytics.py (178-181)
The fix for SQL injection using parameterized queries is incomplete. While it was correctly applied to the get_top_models method, several other methods in the same file (get_performance_metrics and get_usage_trends) still use string formatting to build SQL queries with the days parameter.
Even though the current CLI implementation validates days as an integer, the UsageAnalytics class itself remains vulnerable if used in other contexts or if the validation is bypassed. An attacker could potentially inject SQL commands by providing a malicious string for the days parameter (e.g., 30') OR 1=1 --).
Please apply the same parameterized query pattern to all methods using the days parameter.
src/heidi_cli/cli.py (1067-1199)
This large block of code, which includes the truth_app and its commands, appears to have been removed. This functionality was present on the origin/main branch, and its removal is not mentioned in the pull request description. This seems to be a significant and potentially breaking change. Was the removal of the status command and the truth_app intentional, or could this be an incorrect merge conflict resolution?
src/heidi_cli/doctor/doctor.py (3-16)
This file contains several unused imports (importlib, inspect, sys, subprocess, json, Panel). Removing them will improve code clarity and maintainability.
import ast
import os
from pathlib import Path
from typing import Dict, List, Any, Optional, Set, Tuple
from dataclasses import dataclass
from rich.console import Console
from rich.table import Table
from rich.progress import Progress, SpinnerColumn, TextColumn
src/heidi_cli/doctor/doctor.py (211-212)
The logic to find the imported file is not robust. The check if import_name in other_file: performs a simple substring search of a module name within a file path string. This can lead to incorrect matches (e.g., a module named cli matching a file path .../heidi_cli/utils.py) and result in false positives for circular dependencies. A more reliable approach would involve resolving the import to a full module path and comparing it against a map of module paths to file paths.
