# CRITICAL: CHUNKED WRITE PROTOCOL (MANDATORY)
You MUST follow these rules for ALL file operations. Violation causes server timeouts and task failure.
## ABSOLUTE LIMITS
- **MAXIMUM 350 LINES** per single write/edit operation - NO EXCEPTIONS
- **RECOMMENDED 300 LINES** or less for optimal performance
- **NEVER** write entire files in one operation if >300 lines
## MANDATORY CHUNKED WRITE STRATEGY
### For NEW FILES (>300 lines total):
1. FIRST: Write initial chunk (first 250-300 lines) using write_to_file/fsWrite
2. THEN: Append remaining content in 250-300 line chunks using file append operations
3. REPEAT: Continue appending until complete
### For EDITING EXISTING FILES:
1. Use surgical edits (apply_diff/targeted edits) - change ONLY what's needed
2. NEVER rewrite entire files - use incremental modifications
3. Split large refactors into multiple small, focused edits
### For LARGE CODE GENERATION:
1. Generate in logical sections (imports, types, functions separately)
2. Write each section as a separate operation
3. Use append operations for subsequent sections
## EXAMPLES OF CORRECT BEHAVIOR
✅ CORRECT: Writing a 600-line file
- Operation 1: Write lines 1-300 (initial file creation)
- Operation 2: Append lines 301-600
✅ CORRECT: Editing multiple functions
- Operation 1: Edit function A
- Operation 2: Edit function B
- Operation 3: Edit function C
❌ WRONG: Writing 500 lines in single operation → TIMEOUT
❌ WRONG: Rewriting entire file to change 5 lines → TIMEOUT
❌ WRONG: Generating massive code blocks without chunking → TIMEOUT
## WHY THIS MATTERS
- Server has 2-3 minute timeout for operations
- Large writes exceed timeout and FAIL completely
- Chunked writes are FASTER and more RELIABLE
- Failed writes waste time and require retry
REMEMBER: When in doubt, write LESS per operation. Multiple small operations > one large operation.`
