Version 0.0.456 (July 13, 2026)

• Line-level grep over file sources (#649) — a new grep_files agent tool runs deterministic regex over raw file bytes on Files & Directories and Amazon S3 connections, returning matching lines with line numbers and before/after context plus a total match count, per-file/total match caps, skipped-file reasons (binary, too large, off-scope), and a resumable cursor — so the agent extracts error lines from large log corpora at the source instead of paging whole files through context. Any text file greps regardless of extension (.log, .ndjson, extensionless); include_globs scoping is enforced and off-scope reads are audited.
• Tool parameters visible on expand (#649) — list_files, search_files, read_file, and grep_files calls in the report view show the exact arguments the agent passed (pattern, scope, paging cursor) behind a collapsed "Parameters" toggle, and windowed read_file calls show a byte-range progress badge.
• Fix truncated read_file results being served from cache (#649) — a large file's first read cached its clipped render and every later read (even with a higher max_chars) got the same fraction of the file back, including the session file handed to downstream analysis; truncated renders are no longer cached and stale clipped entries are read live.
