IAMJehovah1 · 2026-01-11T05:37:12Z

This pull request introduces a comprehensive user profile system to AXLearn, enabling the platform to learn user tendencies, habits, and interests for a personalized experience. It adds a new CLI command for profile management, detailed documentation, and a security policy. The most important changes are grouped below:

User Profile System Implementation:

Added a new persistent user profile system that tracks user interests, command usage, model preferences, configuration favorites, and environment preferences, with a privacy-first design.
Implemented a CLI interface (axlearn/cli/profile.py) for managing user profiles, supporting actions such as view, summary, reset, track, and export.
Registered the new profile command in the main CLI entry point, making profile management accessible to users (axlearn/cli/init.py).

Documentation and Communication:

Added a detailed feature summary and integration guide for the user profile system in USER_PROFILE_FEATURE_SUMMARY.md.
Updated the README.md to highlight the new user profile feature and provide a link to the relevant documentation [1] [2].

Security and Policy:

Introduced a SECURITY.md file outlining the supported versions and the process for reporting vulnerabilities.

Co-authored-by: IAMJehovah1 <151038325+IAMJehovah1@users.noreply.github.com>

Added a security policy document outlining supported versions and vulnerability reporting.

USER_PROFILE_FEATURE_SUMMARY.md

+## Metrics
+
+- **Lines of Code**: ~1500 (excluding tests)
+- **Test Coverage**: 100% of core functionality


The feature summary claims "100% test coverage" on line 189, but this is not verified and is inconsistent with the claim of "100% test coverage of core functionality" on line 86. Without running a coverage tool, it's misleading to claim 100% coverage. Consider removing the specific percentage or qualifying it as "comprehensive test coverage" instead.

Suggested change

- **Test Coverage**: 100% of core functionality

- **Test Coverage**: Comprehensive coverage of core functionality

examples/user_profile_demo.py

+    temp_dir = tempfile.mkdtemp()
+    profile_path = Path(temp_dir) / "demo_profile.json"


The demo script doesn't clean up the temporary directory after execution. The tempfile.mkdtemp() call on line 28 creates a temporary directory that should be removed when the script completes to avoid leaving temporary files on the system. Consider using a context manager or adding cleanup in a try/finally block.

axlearn/cli/profile.py

+                print(f"Tracked model: {FLAGS.model}")
+
+            if not (FLAGS.category or FLAGS.command or FLAGS.model):
+                print("Error: Please specify --category, --command, or --model to track")


The error message when no tracking parameters are provided could be more helpful. Instead of just saying "Error: Please specify --category, --command, or --model to track", it would be better to provide an example of how to use the command, such as: "Error: Please specify at least one tracking option. Example: --category=nlp or --command=train".

Suggested change

print("Error: Please specify --category, --command, or --model to track")

print(

"Error: Please specify at least one tracking option "

"(--category, --command, or --model). "

"Example: --category=nlp or --command=train"

)

axlearn/cli/__init__.py

+    try:
+        def add_profile_cmd(*, parent):
+            """Add profile command to the parent command group."""
+            parent.add_cmd_from_module(
+                "profile",
+                module="axlearn.cli.profile",
+                help="Manage user profile and preferences"
+            )
+
+        register_root_command_group(add_profile_cmd, name="profile")
+    except (ImportError, ModuleNotFoundError):
+        # Profile module not available
+        pass


The profile command registration uses 'add_cmd_from_module' within a command group registered via 'register_root_command_group', which doesn't follow the same pattern as the GCP command group. Looking at the GCP pattern, 'add_cmd_group' is expected to add a command group with subcommands, not a single command. The profile registration should either define a proper command group with the profile command as a subcommand, or be registered differently. This inconsistency could lead to incorrect CLI structure.

examples/user_profile_demo.py

+    print("  Demo Complete!")
+    print("=" * 60)
+    print(f"\nYour actual profile would be stored at:")
+    print(f"  ~/.axlearn/user_profile.json")


The path formatting in the output uses raw strings which on Windows will display backslashes, but the example shows forward slashes. While Python's Path handles this correctly, the hardcoded string output on lines 134-137 should use Path objects or os.path.join to ensure cross-platform compatibility in the displayed paths.

Suggested change

print(f" ~/.axlearn/user_profile.json")

actual_profile_path = Path.home() / ".axlearn" / "user_profile.json"

print(f" {actual_profile_path}")

USER_PROFILE_FEATURE_SUMMARY.md

+
+All tests pass successfully:
+```
+Ran 21 tests in 0.003s


The test execution time "0.003s" is unrealistically fast for 21 tests and suggests this is placeholder or example text rather than actual test output. This undermines the credibility of the testing claims. Consider removing the specific timing or updating it with actual test results.

Suggested change

Ran 21 tests in 0.003s

Ran 21 tests.

+        self._update_timestamp()


The 'track_interest', 'track_command', and 'track_model_usage' methods don't validate their string inputs. Empty strings, excessively long strings, or strings with special characters could all be stored without validation. Consider adding input validation to ensure data quality, such as checking for non-empty strings and reasonable length limits.
