Iterative Retrieval

Overview

In large code bases, one search is often not enough. This skill iterates through a search loop, gradually narrowing the scope and pinpointing the relevant code.

4 stage cycle

1. DISPATCH (distribution search)

• Extract search keywords from requirements
• Choose a search strategy:
  • Glob: Search by filename pattern
  • Grep: search by content keywords
  • AST: Search by code structure (function name, class name)
• Launch multiple searches in parallel

2. EVALUATE (evaluation result)

Rate each search result (0-1):

Fraction	Meaning	Action
0.8-1.0	Highly relevant	Reserved, further reading
0.5-0.7	Partially related	Reserved, extract key information
0.2-0.4	Low correlation	Record path, not in depth
0.0-0.1	Not relevant	Discard

3. REFINE (refined query)

Adjust your search strategy based on the evaluation results:

• Highly relevant results → Expand search in the same directory/same module
• Low relevant results → Change keywords or search strategies
• Discover new clues → Additional searches

4. LOOP (loop judgment)

• enough information found → end, output summary
• Insufficient information and rounds < 3 → Back to DISPATCH
• Reached 3 rounds → forced end, output existing information + unresolved issues

Termination condition

• All key questions already answered
• Highly relevant results cover all aspects of requirements
• Maximum rounds reached (3 rounds)

Output format

## Search report

### Rounds: N/3

### Discover
| Documentation | Relevance | Key Information |
|------|--------|----------|
| ...  | 0.9    | ...      |

### Not resolved
- <Questions that still need to be confirmed>

### Search History
1. <query> → <number of results>, highest relevance <score>

VibeGuard Integration

• Marking in search results has been implemented (supports L1 search first and write later)
• Mark when duplicate code is found (supports anti-duplication checking)
