[Refactor] Remove commented code, resolve TODO comments, and fix CI workflow #74

Copilot · 2025-10-05T21:25:23Z

Resolves technical debt by cleaning up commented-out code and implementing functionality marked by TODO comments throughout the codebase. Also fixes broken CI workflow to handle missing API keys gracefully in PR contexts.

Changes Made

Removed Commented Code

Eliminated commented-out import // use crate::config::format_prompt; in src/model.rs
Removed temporary commented-out format_prompt line that was replaced by current implementation

Resolved TODO Comments

Model Configuration (src/model.rs)

DEFAULT_MODEL_NAME: Now uses crate::config::DEFAULT_MODEL instead of hardcoded constant

Model-specific tokenizer: Implemented proper tokenizer selection based on model string:

fn get_tokenizer(model_str: &str) -> CoreBPE {
  match model_str {
    "gpt-4" | "gpt-4o" | "gpt-4o-mini" | "gpt-4.1" | "gpt-4.1-mini" | "gpt-4.1-nano" | "gpt-4.5" => {
      tiktoken_rs::cl100k_base()
    }
    _ => tiktoken_rs::cl100k_base() // fallback
  }.expect("Failed to create tokenizer")
}

Enhanced Configurability (src/config.rs)

Temperature configuration: Added configurable temperature support with DEFAULT_TEMPERATURE = 0.7
Max tokens configuration: Now uses settings.max_tokens instead of hardcoded calculation
Added temperature field to AppConfig struct with corresponding update_temperature() method

Complex Migration (src/multi_step_analysis.rs)

Removed TODO comment: Completely eliminated the TODO comment as requested in PR review

Merge Conflict Resolution

Successfully merged with origin/main: Resolved conflicts in src/config.rs and src/model.rs
Updated model support: Incorporated new model variants (gpt-4.1-mini, gpt-4.1-nano, gpt-4.5) from main branch
Updated default model: Changed DEFAULT_MODEL from "gpt-4o-mini" to "gpt-4.1" to match Model::default()

Test Optimizations

Deterministic temperature: Set temperature to 0.0 in test cases for consistent, reproducible behavior
Enhanced test coverage: Now includes 64 tests across all modules including new model validation tests

CI Workflow Fix

Fixed broken CI: Modified .github/workflows/ci.yml to handle missing OPENAI_API_KEY gracefully in PR contexts from forks
Conditional integration tests: Added logic to skip integration tests with informative message when API key unavailable (common for fork PRs due to security restrictions)
Maintained test coverage: All unit tests, clippy, and formatting checks continue to run normally regardless of API key availability
Security preserved: Secrets remain protected while providing clear feedback about test status

Technical Improvements

The changes improve maintainability by:

Eliminating dead code that created confusion
Making temperature and token limits configurable rather than hardcoded
Implementing proper model-aware tokenizer selection supporting all current model variants
Centralizing constants in the config module
Ensuring full compatibility with the latest main branch changes
Providing robust CI that works reliably in both internal and external contribution contexts

All existing functionality is preserved with backward compatibility. The configurable temperature and max_tokens provide better flexibility for users while maintaining sensible defaults.

Testing: All 64 tests pass, and no new clippy warnings were introduced. CI now handles both scenarios with and without API key access appropriately, preventing failures in PR workflows from forks.

Original prompt

This section details on the original issue you should resolve

<issue_title>[Refactor] Remove commented code and resolve TODO comments</issue_title>
<issue_description>## Context
The codebase has commented-out code and TODO comments that create confusion and indicate incomplete work.

Priority

🟡 HIGH - Should be done early in refactoring

Steps
Find all TODO comments
grep -r "TODO" src/ --include="*.rs" -n
Resolve each TODO:

In src/model.rs:
Line 14: Remove commented import // use crate::config::format_prompt; or use it

Line 25: Move DEFAULT_MODEL_NAME constant to shared location (config.rs or new constants.rs)
Line 214-217: Implement model-specific tokenizer:
fn get_tokenizer(model_str: &str) -> CoreBPE {
    match model_str {
        "gpt-4" | "gpt-4o" | "gpt-4o-mini" | "gpt-4.1" => {
            tiktoken_rs::cl100k_base()
        }
        _ => tiktoken_rs::cl100k_base() // fallback
    }.expect("Failed to create tokenizer")
}
For other TODOs:

If trivial: Implement immediately

If complex: Create separate GitHub issue and reference it in comment

If obsolete: Remove the comment
Remove all commented code
# Search for commented Rust code
grep -r "^[[:space:]]*// " src/ --include="*.rs" | grep -E "(let|fn|pub|struct|impl)"
Remove unless it has explicit justification:
// INTENTIONAL: Keeping as reference for v2 migration
// Issue: #XXX
// Remove after: 2025-Q2
Verify no commented-out imports or function calls remain
Verification Criteria

✅ Pass:

grep -r "TODO" src/ --include="*.rs" returns zero results (or all have issue references)

No commented-out code blocks remain (except explicitly justified)

cargo test passes

cargo clippy shows no new warnings

Model tokenizer selection is implemented (not just TODO)

Estimated Time

2-4 hours

@copilot Fix broken CI

Fixed broken CI in commit c0e5e52. The issue was that integration tests required OPENAI_API_KEY but this secret isn't available in PR contexts from forks. Modified CI workflow to conditionally run integration tests only when API key is available, with informative messages when skipped. All other tests (unit, clippy, fmt) continue to run normally.
