From daba5ea75f01264d13b476349c93359b818a6995 Mon Sep 17 00:00:00 2001 From: ArchieIndian Date: Tue, 17 Mar 2026 00:48:09 +0530 Subject: [PATCH] Add large-file-interceptor skill MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Detects oversized files that would blow the context window, generates structural exploration summaries (JSON schema, CSV columns, Python imports, log patterns), and stores compact reference cards. Supports scan, summarize, restore, and audit. No cron — invoked on demand. Inspired by lossless-claw's large file interception layer.
