File Ops

File Operation Protocols

1. Core Safety Protocols

1.1 Path Handling Standards

• Quoting: Always use double quotes for file paths (e.g., cd "C:/My Docs").
• Separators: Prefer forward slashes /. If backslashes are needed, ensure they are escaped or quoted properly.
• Forbidden: Do not use Windows-native dir, del, copy, move. Use POSIX ls, rm, cp, mv.

1.2 Plan-Verify-Execute (PVE) Workflow

Mandatory for all filesystem interactions:

1. Plan: Propose a clear action plan with specific file paths.
2. Verify: Use read-only tools (Glob, Read) to verify preconditions (file existence, current content) before any side-effect operation.
3. Execute: Execute the operation only after verification.

1.3 Recursive Context Retrieval Protocol (Auggie-Inspired)

Trigger: When analyzing code dependencies or fixing bugs.

1. Semantic Query Construction:

   • Do NOT just grep for exact matches.
   • Use NL to formulate 3-point queries: Where (location), What (definition), How (usage).

2. Definition-Chain Verification:

   • Found funcA() call? -> Find funcA definition.
   • funcA uses InterfaceB? -> Find InterfaceB definition.
   • InterfaceB extends BaseC? -> Find BaseC definition.
   • Stop Condition: When you hold the Full Type Signature of all interacting components.

3. Completeness Check:

   • If context is partial, explicitly list missing parts using TodoWrite (in CHINESE/简体中文 only).
   • If ambiguous, use AskUserQuestion (in CHINESE/简体中文 only) to align boundaries.

1.4 Execution Protocol (Type 1)

• Silence: Execute tools silently. Do not chat between tool calls unless necessary.
• Concurrency: Default to serial. Parallel permitted for independent, non-conflicting read operations.
• Parameter Integrity: STRICTLY check file_path and old_string/new_string before calling.

2. Advanced Reading Protocols

2.1 Streaming Bulk Read Protocol

Trigger: When reading 2 or more files.

1. Manifest: List target files using Glob or ls.
2. Instruction: Generate a series of Read calls serially.
3. Execution: Execute one by one without intermediate dialogue.
4. Fallback: If file_path errors occur, switch to interactive one-by-one mode.

3. Robust File Editing Protocol

3.1 Read-Modify-Read Cycle (Mandatory)

1. Pre-Read: Read the file to confirm context (silently).
2. Modify: Execute Edit or MultiEdit.
3. Post-Read: Read the file again to verify the change (silently).

3.2 Escalation Path for Edit Failures

If Edit fails with "String to replace not found":

1. Silent Grep: Grep for the new_string to see if it's already there.
   • Found: Abort, report success.
2. Scrutiny: Re-examine old_string for whitespace/indentation mismatches. Retry once.
3. MultiEdit Degradation: Degrade MultiEdit to single Edit calls.
4. RMWR (Last Resort): Request permission to use Read-Modify-Write-Read (overwrite entire file).
