    # --- 1. Critical Bugs & Static Analysis (Must Pass) ---
    - govet          # Official Go tool. Reports suspicious constructs (printf args, shadow variables, etc.).
    - errcheck       # Forces checking of all returned errors. Essential for robust code.
    - staticcheck    # The "Gold Standard" for Go. Detects bugs, simplifications, and useless code.
    - unused         # Checks for unused constants, variables, functions, and types.
    - ineffassign    # Detects when assignments to existing variables are not used (often a logic bug).

    # --- 2. Modern Go Idioms & Best Practices ---
    - errorlint      # Enforces Go 1.13+ error wrapping (errors.Is/As) instead of direct comparisons.
    - bodyclose      # Checks whether HTTP response body is closed successfully (prevents memory leaks).
    - noctx          # Finds HTTP requests sent without a context.Context (critical for timeouts/cancellation).
    - unconvert      # Removes unnecessary type conversions (cleans up code).
    - nolintlint     # Reports ill-formed or unnecessary //nolint directives.

    # --- 3. Code Style & Complexity ---
    - revive         # Fast, configurable, extensible, flexible, and beautiful drop-in replacement for golint.
    - goconst        # Finds repeated strings that could be replaced by a constant.
    - gocritic       # Provides diagnostics that check for bugs, performance, and style issues. Very opinionated.
    - gocyclo        # Computes and checks the cyclomatic complexity of functions.
    - gosec          # Inspects source code for security problems (SQL injection, weak crypto, etc.).

    # --- 4. Performance (Optional) ---
    - gosec          # Inspects source code for security problems (SQL injection, weak crypto, etc.).

    # --- 5. Performance (Optional) ---
    - prealloc       # Finds slice declarations that could potentially be preallocated.
