v0.0.482

Version 0.0.482 (July 22, 2026)

• Many-file agents no longer flood the context window — the <files> section used to inline every attached file's full preview (sample rows, PDF text) into the planner prompt on every reasoning step, and the code-generation prompt carried the same previews twice; an agent whose file library holds dozens of files made every new chat pay ~7k tokens per wide spreadsheet with no cap and no trimming. Files now render at two tiers: files the user @-mentioned or attached with the current message keep their full preview, while files snapshotted from an agent's library render as a one-line index (type, row/column counts, sheet names, column headers) that the agent expands on demand with read_file / inspect_data — access is unchanged, only the eager prompt cost is gone. Remaining user uploads stay rich newest-first within a shared token budget (small chats with up to 3 files are untouched), the coder's <excel_files> block is now a stable index→file mapping instead of a second full copy, the Context Browser finally shows a files line item in the section-size breakdown, and the context trimmer can cut the files section as a backstop before it would ever touch conversation history or schemas. In a live test, a chat with six wide CSVs dropped from ~41k to ~1.6k tokens of file context with the model still answering file questions correctly from the index.
