Verify Multilang Support

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

1. Preparation

   • Locate test/sample-projects.
   • Iterate through the language-specific sample projects listed below.

2. 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

3. 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.

4. 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.
