LOC Optimization Knowledge

Config File: `.claude/loc-guardian.local.md`

The /loc-guardian:init command creates this file. Format:

---
max_pure_loc: 350
---

Followed by a markdown body containing the project's extraction rules — user-defined, project-specific patterns for how to split oversized files. Example format:

## Extraction Rules

- [What to extract] → `[target file naming convention]`
- [What to extract] → `[target file naming convention]`

The actual rules vary by project and are written by the user during init. The agent MUST read this file and use the user's extraction rules verbatim when making suggestions. If the file has no extraction rules in the body, fall back to generic patterns (see below).

Generic Optimization Patterns (Fallback)

Use these ONLY when the project has no extraction rules configured:

Eliminate Duplication

Repeated patterns that differ only in data → data-driven approach
Copy-pasted blocks with slight variations → parameterized function

Simplify Conditionals

Nested if/else → early returns or guard clauses
Long switch → lookup object/map
Repeated null checks → optional chaining or nullish coalescing

Leverage Framework Features

Manual DOM manipulation → declarative framework patterns
Hand-rolled state management → built-in hooks/stores
Imperative iteration → declarative array methods

Remove Dead Code

Unused imports, variables, functions
Commented-out code blocks
Feature flags for features that shipped long ago
