## 🐛 Issues Found

### Issue #1: Missing Starlette Dependency ⚠️
**Severity:** Medium (Test infrastructure)
**File:** `tests/test_server_fastmcp_http.py`
**Error:** `ModuleNotFoundError: No module named 'starlette'`

**Root Cause:**
- Test file requires `starlette.testclient` for HTTP transport testing
- Dependency not in `pyproject.toml`

**Impact:**
- Cannot run MCP HTTP transport tests
- Test collection fails

**Recommendation:**
```toml
# Add to pyproject.toml [dependency-groups.dev]
"starlette>=0.31.0",  # For MCP HTTP tests
"httpx>=0.24.0",      # TestClient dependency
```

### Issue #2: Pydantic V2 Deprecation Warnings ⚠️
**Severity:** Low (Future compatibility)
**Files:**
- `src/skill_seekers/embedding/models.py` (3 warnings)

**Warning:**
```
PydanticDeprecatedSince20: Support for class-based `config` is deprecated,
use ConfigDict instead. Deprecated in Pydantic V2.0 to be removed in V3.0.
```

**Affected Classes:**
- `EmbeddingRequest` (line 9)
- `BatchEmbeddingRequest` (line 32)
- `SkillEmbeddingRequest` (line 89)

**Current Code:**
```python
class EmbeddingRequest(BaseModel):
    class Config:
        arbitrary_types_allowed = True
```

**Recommended Fix:**
```python
from pydantic import ConfigDict

class EmbeddingRequest(BaseModel):
    model_config = ConfigDict(arbitrary_types_allowed=True)
```

### Issue #3: PyGithub Authentication Deprecation ⚠️
**Severity:** Low (Future compatibility)
**File:** `src/skill_seekers/cli/github_scraper.py:242`

**Warning:**
```
DeprecationWarning: Argument login_or_token is deprecated,
please use auth=github.Auth.Token(...) instead
```

**Current Code:**
```python
self.github = Github(token) if token else Github()
```

**Recommended Fix:**
```python
from github import Auth

if token:
    auth = Auth.Token(token)
    self.github = Github(auth=auth)
else:
    self.github = Github()
```

### Issue #4: pathspec Deprecation Warning ⚠️
**Severity:** Low (Future compatibility)
**Files:**
- `github_scraper.py` (gitignore loading)
- `codebase_scraper.py` (gitignore loading)

**Warning:**
```
DeprecationWarning: GitWildMatchPattern ('gitwildmatch') is deprecated.
Use 'gitignore' for GitIgnoreBasicPattern or GitIgnoreSpecPattern instead.
```

**Recommendation:**
- Update pathspec pattern usage to use `'gitignore'` pattern instead of `'gitwildmatch'`
- Ensure compatibility with pathspec>=0.11.0

### Issue #5: Test Collection Warnings ⚠️
**Severity:** Low (Test hygiene)
**File:** `src/skill_seekers/cli/test_example_extractor.py`

**Warnings:**
```
PytestCollectionWarning: cannot collect test class 'TestExample' because it has a __init__ constructor (line 50)
PytestCollectionWarning: cannot collect test class 'TestExampleExtractor' because it has a __init__ constructor (line 920)
```

**Root Cause:**
- Classes named with `Test` prefix but are actually dataclasses/utilities, not test classes
- Pytest tries to collect them as tests

**Recommendation:**
- Rename classes to avoid `Test` prefix: `TestExample` → `ExtractedExample`
- Or move to non-test file location
