Verify Multi-Language Support

Overview

As an agent, your goal is to verify that the code-index-mcp server can correctly index, deep-index, and search code across different programming languages. Use the MCP tools available in your environment to interact with the sample projects located in test/sample-projects.

Important: This is not a "does it return something" test. You must compare the actual get_file_summary output against the expected baselines below and flag any discrepancy in language, symbol_count, function/method/class names, called_by relationships, and imports.

Instructions

Preparation
- Locate test/sample-projects.
- Iterate through the language-specific sample projects listed below.
Verification Loop For each language, perform these steps sequentially:

a. Set Path
- Call set_project_path with the absolute path to the sample project.
b. Shallow Index
- Call refresh_index to build the shallow (file-list) index.
c. Deep Index
- Call build_deep_index to run full symbol extraction.
d. Search & Verify
- Run the listed Verification Query using search_code_advanced.
- Treat the query as a literal search unless the table explicitly says otherwise.
e. Deep Summary Check — compare against baseline
- Call get_file_summary for the Preferred File.
- Compare the result against the Expected Baseline for that language (see section below).
- Check ALL of the following:
  1. language field matches expected value.
  2. symbol_count is >= the expected minimum.
  3. Every name listed in expected_functions appears in the functions list.
  4. Every name listed in expected_methods appears in the methods list.
  5. Every name listed in expected_classes appears in the classes list.
  6. For each entry in expected_called_by, verify the named symbol's called_by list contains the expected callers.
  7. Every entry in expected_imports appears in the imports list.
- Mark PASS only if ALL checks pass. If any single check fails, mark FAIL and record which check failed.
f. Symbol Body Check
- Call get_symbol_body for the Expected Symbol in the Preferred File.
- Pass when status is "success" and code is non-empty.
g. Record Status
- Track per language:
  - SEARCH: PASS/FAIL
  - SUMMARY: PASS/FAIL (with details on which checks failed)
  - SYMBOL_BODY: PASS/FAIL
  - FINAL: PASS/FAIL
Behavior Smoke Checks
- After the language loop, run at least one literal-mode smoke check with a regex-like string such as get.*Data and confirm it remains literal when regex mode is omitted or disabled.
- If native regex support is available, run one explicit regex smoke check and confirm it behaves as regex.
- Report these separately from the language table.
Reporting
- Summarize each language with its phase-level statuses in a table.
- For any FAIL, list the specific check that failed and the actual vs expected values.

Tips

Confirm the sample project's real relative path before assuming the table is current.
Objective-C does not have a subdirectory — its files sit directly under test/sample-projects/objective-c/.
Python's sample project also has files at the top level (cli.py, __init__.py).
If a baseline check fails, read the actual file to determine whether the baseline is stale (sample project changed) or the indexer has a bug. Update the baseline if the sample project legitimately changed.
When new languages are added, add a baseline section here based on the actual get_file_summary output.
