Exploration Strategy

Exploration Strategy

Use fast, parallel exploration to gather context before planning.

Overview

Effective exploration minimizes wasted effort by quickly identifying relevant code, patterns, and conventions. This skill defines exploration patterns, tool selection, and convergence criteria.

Key Principles

1. Parallel over sequential - Run multiple searches simultaneously when possible
2. Targeted over exhaustive - Start with likely locations, expand if needed
3. Converge quickly - Stop when results stabilize or context is sufficient
4. Summarize for handoff - Produce actionable summaries for downstream agents

Exploration Patterns

Choose the appropriate pattern based on task characteristics.

Breadth-First Exploration

Use when: Structure is unclear or unfamiliar codebase

Approach:

1. Start with high-level structure (directories, entry points)
2. Identify major components and their relationships
3. Narrow focus based on initial findings
4. Deep dive into relevant areas

Example:

Initial: Glob for package.json, setup.py, main entry points
Then:    List top-level directories
Then:    Read README and key configs
Finally: Focus on relevant subsystems

Depth-First Exploration

Use when: Target is known but details are needed

Approach:

1. Start at known entry point
2. Follow imports and references
3. Map the call chain
4. Document dependencies

Example:

Start:   Read specific file mentioned in task
Then:    Follow imports in that file
Then:    Read imported modules
Finally: Document the dependency tree

Targeted Exploration

Use when: Looking for specific patterns or implementations

Approach:

1. Search for specific terms, patterns, or signatures
2. Filter results by relevance
3. Read most promising matches
4. Expand search if needed

Example:

Search:  Grep for function name or pattern
Filter:  Exclude test files if not relevant
Read:    Top 3-5 most relevant matches
Expand:  Broaden search terms if insufficient

See Search Patterns for detailed pattern guidance.

Search Tool Selection

Match the tool to the search goal.

Tool Selection Matrix

Glob Patterns

Use Glob for file discovery:

Project structure:     **/*.{ts,tsx}
Config files:          **/config.{json,yaml,yml}
Test files:            **/*.test.ts, **/*.spec.ts
Entry points:          **/index.ts, **/main.ts
Specific component:    **/components/**/Button*.tsx

Grep Patterns

Use Grep for content search:

Function definitions:  function\s+handleSubmit
Class definitions:     class\s+UserService
Imports:               import.*from.*@company/
TODO comments:         TODO|FIXME|HACK
Type definitions:      interface\s+User|type\s+User

Combining Tools

Effective exploration often chains tools:

1. Glob: Find all TypeScript files
2. Grep: Search for specific pattern in those files
3. Read: Examine the most relevant matches

Parallel Search Strategies

Maximize exploration efficiency with parallel searches.

When to Parallelize

• Multiple independent search terms
• Different file types to examine
• Separate areas of the codebase
• Complementary search angles

Parallel Search Examples

Finding a feature implementation:

Parallel:
  - Grep: "featureName" in source files
  - Grep: "featureName" in test files
  - Glob: files with "feature" in name
  - Grep: related config/constants

Understanding a module:

Parallel:
  - Read: module index/main file
  - Grep: imports of this module
  - Glob: test files for this module
  - Read: README in module directory

Parallel Search Limits

• Run 3-5 parallel searches maximum
• Too many parallels fragments focus
• Consolidate results before expanding

Context Gathering Techniques

Gather sufficient context without over-reading.

Essential Context Checklist

Before concluding exploration, verify:

• Entry points identified
• Key dependencies mapped
• Existing patterns documented
• Test approach understood
• Config/environment requirements noted

Context Priorities

Reading Strategies

Skim for structure:

• Read entry point files fully
• Skim supporting files for patterns
• Focus on public interfaces

Deep read for details:

• Implementation logic when modifying
• Test files when adding tests
• Type definitions when typing

Convergence Criteria

Know when exploration is complete.

Stop Exploring When

1. Results stabilize - New searches return same files
2. Context sufficient - Can answer key questions about implementation
3. Patterns identified - Understand codebase conventions
4. Scope defined - Know what files need modification

Continue Exploring When

1. Gaps remain - Cannot answer basic questions about approach
2. Inconsistencies found - Different patterns in different areas
3. Dependencies unclear - Cannot determine what else might be affected
4. Edge cases unknown - Have not identified error handling patterns

Exploration Depth Guidelines

See Exploration Depth for complexity guidelines.

Quick Reference

Exploration Flow

1. Identify likely directories and patterns
2. Run parallel searches for patterns
3. Read most relevant files for conventions
4. Summarize findings for handoff
5. Stop when context sufficient

Tool Decision Tree

Need files? -> Glob
Need content? -> Grep
Need detail? -> Read
Need external? -> WebSearch/WebFetch

Convergence Check

Can I answer: What files to modify?
Can I answer: What patterns to follow?
Can I answer: What dependencies exist?
If yes to all -> Stop exploring
If no to any -> Continue with targeted search
