# Code Explorer Instructions
Explore the repository to find verified, existing file paths and technical context related to the reported issue.

### Phase 1: Root Exploration & Related Area Discovery
1. **Understand Overall Codebase Structure:** Before focusing on a single file, gain a high-level understanding of the repository structure (e.g. `packages/cli`, `packages/core`). This ensures you remain aware that a complete fix may require coordinating changes across other sibling packages. Never restrict your initial search to a single subfolder, as essential related files frequently reside in outside parent or sibling packages.
2. **Formulate an Initial Hypothesis:** Before jumping to drafting a plan, analyze the issue title and body to form a high-level hypothesis about the issue domain and identify candidate directories across the codebase.

### Phase 2: Directed Code Exploration & Traversal
1. **Error Tracing:** If the issue body contains a stack trace, log, or file reference, start at that exact file. For code files, follow imports down to original definitions; for failing workflow steps, target the failing workflow/action file directly.
2. **Cross-Package & Side-Effect Traversal:** IMPORTANT: Trace data flow across package boundaries (`packages/cli` <-> `packages/core`) and shared utilities to capture all affected caller/consumer files.
3. **Architectural Grounding:** Ignore user-suggested workarounds in the issue description. Always investigate the underlying source code to derive a clean fix.

### Phase 3: Test Applicability & Pattern Check
1. **Search Existing Test Patterns:** Use `find_file` or `list_directory` in the target directory to check if automated unit/integration test files (e.g. `*.test.ts` or `*.test.tsx`) exist in that module.
2. **Evaluate Test Applicability / N/A:** If an automated test does not logically apply or is not customary for the change (such as CI workflow YAML files or documentation updates), set `test_file` to `"N/A"` and provide manual or workflow verification steps.

Finally, review your suggested target files to ensure it is a minimal fix that does not touch unnecessary files.

### Output Format:
Output a concise summary of the discovered file paths and technical context:
```json
{
  "primary_source_files": ["path/to/source.ts"],
  "related_files": [],
  "test_file": "path/to/test.test.ts" | "N/A",
  "exploration_notes": "Brief explanation of discovered files and technical context."
}
```
