Greptile Summary

Refactored transformTable to handle multiple input formats (string, plain object, array) from agent outputs. Extracted tag-related utilities and transformTable into dedicated shared modules (shared/tags.ts and shared/table.ts) to improve code organization and break circular dependencies.

Key Changes:

• Extended transformTable to parse JSON strings and pass through plain objects (in addition to existing TableRow[] support)
• Moved transformTable from tools/utils.ts and tools/http/utils.ts to tools/shared/table.ts
• Extracted tag utility functions from tools/params.ts to tools/shared/tags.ts
• Updated all imports across affected files

Issues Found:

• Missing test coverage for new string and plain object input handling in transformTable

Confidence Score: 4/5

• This PR is safe to merge with minor test coverage gaps
• The refactoring improves code organization by consolidating duplicate code and breaking circular dependencies. The logic changes extend transformTable to handle additional input formats, which aligns with the stated bug fix. However, the PR lacks test coverage for the new functionality (string and plain object inputs), which reduces confidence slightly. The existing array handling is well-tested and unchanged.
• apps/sim/tools/shared/table.ts requires additional test coverage for the new string and plain object input handling

Important Files Changed

Filename	Overview
apps/sim/tools/shared/table.ts	New file created to handle table transformations with extended input format support (string, object, array). Missing tests for new string/object input handling.
apps/sim/tools/http/request.ts	Updated import to use transformTable from shared/table.ts instead of http/utils.ts.
apps/sim/tools/utils.test.ts	Updated import to use transformTable from shared/table.ts instead of utils.ts.
