Summary

Adds an opt-in BSL (1C:Enterprise) context configuration for Serena.

Closes #1378

Changes

  • New file: src/serena/resources/config/contexts/bsl.yml

The context provides:

  • BSL-specific prompt guidance (Cyrillic identifiers, EDT project structure, export visibility semantics)
  • Tool allowlist optimized for BSL (symbol navigation, pattern search)
  • execute_shell_command excluded (BSL has no REPL equivalent)

Why opt-in

BSL is a niche language compared to Python/TS/Go/Rust. This context activates only via --context bsl, ensuring zero impact on default Serena behavior while providing value to 1C:Enterprise developers.

The Serena codebase already includes experimental BSL Language Server support (bsl_language_server.py). This context complements it with BSL-specific tooling guidance.

Testing

  • YAML validates against existing context format (matches agent.yml, codex.yml patterns)
  • No code changes — pure configuration addition
  • Opt-in only — no default behavior change

Checklist

  • Context file follows existing format conventions
  • No changes to core logic or default behavior
  • execute_shell_command excluded (appropriate for BSL)

Thanks for the PR.

I don't think we need a separate context, the bsl server won't be started if there are no bsl files in the project.

I fixed the formatting to allow CI to start, but even before a proper review I see that the tests are completely off. Pls fix them, then I will re-review

  1. Never use try-skip, this masks failures. Same for if len(symbols) > 0:
  2. Never have tests just asserting the type of the result, always assert the content
  3. A test uses the not-existing method request_workspace_symbols
  4. Tests use an older api and hence the wrong types (would be caught by a type checker), e.g. symbols = language_server.request_document_symbols(file_path) should be replaced by symbols = language_server.request_document_symbols(file_path).get_all_symbols_and_roots()[0]
  5. Tests need to run in CI, pls add a setup step for BSL language server there
