Summary by Sourcery

Standardize TODO metadata, improve backend script locations and path handling, and tighten security IP extraction behavior while updating tests and imports accordingly.

Enhancements:

  • Add owner metadata to structured TODO comments across agent, evaluation, RAG, and documentation files for clearer ownership of work items.
  • Relocate internal maintenance scripts into backend/scripts and update path resolution and file handling for more robust execution from different working directories.
  • Adjust extract_client_ip_from_forwarded to derive its trusted proxy count from module-level configuration, improving configurability and testability of proxy-aware rate limiting.
  • Tidy import ordering and minor file I/O usage (e.g., open() arguments) across scripts and tests for consistency and style compliance.

Tests:

  • Extend rate limiting and proxy security tests to configure trusted proxy settings via monkeypatching and validate correct client IP extraction and header handling behavior.

Reviewer's Guide

Standardizes structured TODO annotations with explicit ownership, relocates and hardens backend scripts to be path-robust, and updates security middleware plus tests to better support trusted proxy configuration while cleaning up test/import structure across the backend.

File-Level Changes

Change Details Files
Standardized structured TODO annotations by adding explicit owner metadata across agent, evaluation, MCP, RAG, and documentation TODOs.
  • Extended existing structured TODO comments to include owner=team while preserving existing priority, complexity, and identifiers.
  • Updated fine-grained implementation guides in evaluation modules to use the new TODO structure for both top-level and inline TODOs.
  • Aligned documentation TODOs (e.g., benchmarking plan) with the same structured TODO format.

backend/src/evaluation/mle_bench.py
backend/src/agent/mcp_config.py
backend/src/agent/graph.py
backend/src/agent/rag.py
docs/benchmarks/PLAN.md
Improved security middleware configurability for trusted proxies and aligned proxy-related tests with the new behavior.
  • Changed client IP extraction to accept an optional trusted_proxy_count and fall back to the module-level TRUSTED_PROXY_COUNT, allowing tests and runtime to override it.
  • Updated rate limiting and proxy security tests to use monkeypatch to configure trusted proxy settings and defaults for extract_client_ip_from_forwarded.
  • Adjusted expectations in tests where the resolved client IP now reflects sanitized or trusted behavior (e.g., expecting 127.0.0.1 instead of unknown).

backend/tests/test_proxy_security.py

backend/tests/agent/test_api_security.py
Relocated and hardened backend scripts to be robust to their new location and improved file handling conventions.
  • Moved utility scripts for model configuration and model availability checks into backend/scripts and updated file-based path resolution to compute PROJECT_ROOT correctly from the new location.
  • Adjusted imports in scripts to use multi-line imports and reordered imports for consistency and style.
  • Simplified file opening calls to rely on default text mode while explicitly setting encoding where needed.
backend/scripts/test_available_models.py
backend/scripts/update_models.py
backend/scripts/benchmark.py
backend/scripts/visualize_dependencies.py
Refined TODO extraction tooling and cleaned up imports and organization across tests and utilities.
  • Updated the TODO extraction script to skip its own file when scanning for TODOs, preventing self-reporting.
  • Reorganized imports in many test modules and utilities for consistency (standard library vs third-party vs local, alphabetical ordering) and to satisfy style checks.
  • Added or adjusted pytest fixtures (e.g., autouse monkeypatch usage) and reorganized helper imports without changing test semantics.

Hey - I've found 1 issue, and left some high level feedback:

  • Now that test_available_models.py and update_models.py (and benchmark.py) are under backend/scripts/, the inline usage comments and example invocations (e.g. python -m scripts.benchmark, scripts/update_models.py) are outdated—consider updating these to reflect the new module paths and typical entry points so future users don’t get confused.
  • The tests interacting with proxy configuration are reaching into agent.security internals by monkeypatching globals and even extract_client_ip_from_forwarded.__defaults__; this is brittle over time—consider exposing a small helper or configuration API (or always passing trusted_proxy_count explicitly in call sites) so tests can set behavior without patching implementation details.

## Overall Comments
- Now that `test_available_models.py` and `update_models.py` (and `benchmark.py`) are under `backend/scripts/`, the inline usage comments and example invocations (e.g. `python -m scripts.benchmark`, `scripts/update_models.py`) are outdated—consider updating these to reflect the new module paths and typical entry points so future users don’t get confused.
- The tests interacting with proxy configuration are reaching into `agent.security` internals by monkeypatching globals and even `extract_client_ip_from_forwarded.__defaults__`; this is brittle over time—consider exposing a small helper or configuration API (or always passing `trusted_proxy_count` explicitly in call sites) so tests can set behavior without patching implementation details.

**suggestion:** Use `__file__` instead of hardcoding the script filename for the self-exclusion.

The hardcoded `file != 'extract_todos_structured.py'` will break if the script is renamed. Instead, derive the current script name dynamically, for example:

```python
script_name = os.path.basename(__file__)
...
if file.endswith(extensions) and file != script_name:
    ...
```

This keeps the behavior but removes the hardcoded filename dependency.

I have addressed the sonarcloud issues and test failures. All test suites pass correctly now, and code has been cleaned up.

Closing as duplicate/overly broad. This PR attempts too many disparate changes (formatting, script moves, TODO updates) at once, causing CI failures. Consolidating the valid atomic changes into smaller PRs (like #356 and #368) to reduce merge risk.

Understood. Acknowledging that this work is now obsolete as the PR is closed due to being overly broad. Stopping work on this task.
