Summary of Changes
Hello @groupthinking, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request introduces a substantial upgrade to the guardian_linter_watchdog.py script, transforming it from a basic linter watchdog into a more comprehensive 'Guardian Agent'. The core change involves migrating from a polling-based file monitoring system to an event-driven one, which is more responsive and resource-efficient. Beyond linting, the agent now proactively checks for common code placeholders and automatically performs test coverage analysis, providing immediate feedback on code quality and completeness.
Highlights
- Core Refactor: Event-Driven File Monitoring: I've significantly refactored the file monitoring mechanism in
guardian_linter_watchdog.py. The previous polling-based approach usingasynciohas been replaced with an event-driven system leveraging thewatchdoglibrary. This change should provide more immediate and efficient detection of file modifications. - New Feature: Placeholder Detection: The Guardian Agent now includes a new capability to scan modified Python files for common placeholder strings such as
TODO,FIXME,XXX, andPLACEHOLDER. This helps in identifying incomplete or temporary code sections that need attention. - New Feature: Automated Test Coverage Analysis: I've integrated automated test coverage analysis into the Guardian Agent. Upon detecting a file change, the script will now run
pytestandcoverage.pyto assess the project's test coverage, reporting the percentage and flagging if it falls below a configurable minimum (defaulting to 80%). - Simplified Linter Execution: The
pylintexecution logic has been updated to use synchronoussubprocess.run, simplifying the code and improving error handling for cases wherepylintis not found or encounters issues.

Pull Request Overview
This PR replaces a polling-based linter watchdog with a filesystem‐event-driven GuardianAgent that lints on modifications, checks for placeholders, and runs test coverage analysis.
- Introduces
watchdogto trigger linting, placeholder checks, and coverage on file changes - Adds placeholder scanning and a minimum coverage threshold
- Removes async polling, logging, and module docstring

guardian_linter_watchdog.py:1
- [nitpick] Add a module-level docstring (and shebang if needed) to describe the script's purpose, improving clarity for new readers.
import os
guardian_linter_watchdog.py:14
- [nitpick] Currently only on_modified events are handled; you may also want to handle on_created (and possibly on_moved) to ensure newly added files are linted immediately.

Code Review
The code changes introduce a watchdog to monitor file changes, run linters, check for placeholders, and analyze test coverage. There are critical issues that will prevent it from running correctly, including a missing dependency, a typo in a command, and incorrect parsing of the test coverage report. Additionally, running the entire test suite on every file change is a major performance concern.

21-31: Well-implemented linter execution with proper error handling.The method correctly handles both linter failures and missing pylint installation.
57-69: Clean implementation of the watchdog observer pattern.The main execution block properly sets up the file system observer with appropriate cleanup on interruption.
41-55: [web_search]Which versions of coverage.py support the "--format=total" option for the report command?
