feat(webfetch-guard): add grace period for previous year searches #9
Conversation
During Jan-Mar, allow searches for the previous year since content from that year is still relevant at year start. Searches for 2+ years ago are still blocked. After March, previous year is blocked. Also adds user-visible output message when searches are blocked, showing current date and prompting to use current year. Simplified code by consolidating helper functions and removing unnecessary abstractions. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Code Review
This pull request introduces a grace period for previous-year searches in the webfetch guard, a valuable enhancement. The code is also simplified by consolidating helper functions, which improves maintainability.
My review focuses on a few key areas for improvement:
- I've identified a potential for false positives in the year-detection logic and suggested a more robust implementation using regular expressions.
- I've pointed out a magic number that should be converted to a constant for better readability.
- I've also suggested a minor tweak to an error message for a more consistent tone.
Overall, these are solid changes that improve the functionality of the hook. Addressing these points will make the implementation more robust and maintainable.

Good use of dynamic test naming based on the current date. Ensure that the conditional naming remains in sync if the grace period logic is ever adjusted. - Reason this comment was not posted:

2. webfetch-guard/scripts/webfetch-guard.py:72
- Draft comment:
The choice of a 10‐year range for blocked years (using current_year - 10) is hardcoded. Consider adding a comment or making it configurable if future changes are anticipated. - Reason this comment was not posted:
Comment looked like it was already resolved.
3. webfetch-guard/scripts/webfetch-guard.py:120
- Draft comment:
Non-year-referenced inputs result in a silent pass (no output). This is intended, but consider documenting this behavior explicitly for future maintainers. - Reason this comment was not posted:
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 15% vs. threshold = 50% The comment is suggesting to add documentation for the implicit behavior when no year references are found. However, this falls into several problematic categories: 1) It's asking for documentation rather than pointing out a code issue, 2) The behavior is actually quite clear from reading the code - if neither condition is met, the function exits normally with exit code 0 (which is the default success behavior), 3) The old code had an explicit sys.exit(0) at the end which was removed, but this is actually cleaner since Python functions naturally exit anyway, 4) This is not a code change that needs to be made - it's a suggestion to add comments "for future maintainers" which is speculative and not actionable. The behavior might not be immediately obvious to someone unfamiliar with hook systems - they might wonder what happens when the script exits with code 0 without printing JSON output. Perhaps there's value in documenting this for clarity, especially since the other paths explicitly print JSON responses. While the behavior might not be immediately obvious, the comment is still asking for documentation rather than identifying a bug or necessary code change. The rules explicitly state not to make comments that are purely informative or obvious. The fact that the old code explicitly had this case documented and it was intentionally removed suggests the author made a deliberate choice. Additionally, this is the kind of thing that would be clear from understanding the broader system context, which we're told to assume the author has. This comment should be deleted. It's asking for documentation to be added rather than identifying a code issue. The behavior (silent pass when no year references are found) is clear from the code structure, and the old code's explicit handling of this case was intentionally removed in this refactor. This is not an actionable code change.

You can customize 
- Replace substring matching with regex word boundaries in find_blocked_year() to prevent false positives (e.g., "1202345" matching "2023")
- Extract magic number 10 to YEAR_BLOCK_RANGE constant for better readability and maintainability
- Update error message tone from informal ("Hey, you searched an old year... Try again.") to neutral ("Your search included an outdated year.")
Addresses PR #9 review threads:
- Thread 1: False positive prevention with regex word boundaries
- Thread 2: Magic number extraction to constant
- Thread 3: Message tone consistency

Review Feedback ResolutionAll three review comments have been addressed and implemented: 1. False Positive Prevention (HIGH)Status: Fixed ✓ Replaced the substring matching approach ( The implementation also sorts blocked years in descending order to check more recent years first as a minor optimization. 2. Magic Number Extraction (MEDIUM)Status: Fixed ✓ Extracted the magic number 3. Message Tone Consistency (MEDIUM)Status: Fixed ✓ Updated the error message from the informal "Hey, you searched an old year. The current time and date are: {timestamp}. Try again." to the more neutral "Your search included an outdated year. The current time is {timestamp}." This maintains consistency with the rest of the script's messaging. All changes have been tested to ensure no false positives occur and existing functionality remains intact. |

Pull request overview
This PR adds grace period logic to the webfetch-guard plugin, allowing previous year searches during January-March while blocking searches for years 2+ years old. After March, both previous year and older years are blocked. The implementation also adds user-visible stderr messages and simplifies the codebase by consolidating helper functions.
Changes:
- Grace period logic: Jan-Mar allows previous year, Apr-Dec blocks previous year and older
- User-facing stderr messages added to inform users when searches are blocked
- Code simplification: merged helper functions and removed unnecessary abstractions

1. webfetch-guard/scripts/webfetch-guard.py:36
- Draft comment:
The new _is_year_reference helper centralizes the year detection logic and excludes identifier-style prefixes (e.g., 'RFC', 'ISO'). Consider making the list of excluded prefixes configurable for easier extensibility in the future. - Reason this comment was not posted:
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 20% vs. threshold = 50% The comment is about code that was actually changed (the new function was added). It's a code quality suggestion about making the hardcoded list of prefixes ('rfc', 'iso') configurable. However, this is a speculative suggestion - it's saying "consider making this configurable for easier extensibility in the future" without evidence that this extensibility is actually needed. The current implementation with just 'rfc' and 'iso' seems reasonable and simple. The comment doesn't point to a clear problem or bug, just suggests a potential future improvement. This falls into the category of speculative refactoring suggestions without clear justification. The comment is about actual changes and suggests a concrete refactoring (making the prefix list configurable). It could be argued that this is an actionable code quality suggestion, which the rules say are good if they are "actionable and clear." While the suggestion is technically actionable, it's speculative about future needs ("for easier extensibility in the future") without evidence that such extensibility is actually required. The current implementation is simple and clear with just two prefixes. Adding configurability would add complexity without a demonstrated need. This is more of a "nice to have" suggestion rather than a clear code improvement. This comment should be deleted. It's a speculative suggestion about future extensibility without clear evidence that the added complexity is needed. The current simple implementation with two hardcoded prefixes is reasonable and clear.

Changing YEAR_BLOCK_RANGE to 2 aligns with the new grace period logic. Ensure that both documentation and tests reflect this update accurately. - Reason this comment was not posted:

3. webfetch-guard/scripts/webfetch-guard.py:105
- Draft comment:
Detection of the current_year via a simple substring ('in' check) might yield false positives in non-date contexts. Consider using the _is_year_reference helper here for consistency with blocked year detection. - Reason this comment was not posted:
