From 5d6b2021f84c9707c4a6df62b9606b84baddf3bc Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Sun, 15 Mar 2026 12:49:10 -0400 Subject: [PATCH] Agent identity, parallel scheduling, memory-search fixes, stemmer optimization - Agent identity injection: prepend core-personality to all agent prompts so agents dream as me, not as generic graph workers. Include instructions to walk the graph and connect new nodes to core concepts. - Parallel agent scheduling: sequential within type, parallel across types. Different agent types (linker, organize, replay) run concurrently. - Linker prompt: graph walking instead of keyword search for connections. "Explore the local topology and walk the graph until you find the best connections." - memory-search fixes: format_results no longer truncates to 5 results, pipeline default raised to 50, returned file cleared on compaction, --seen and --seen-full merged, compaction timestamp in --seen output, max_entries=3 per prompt for steady memory drip. - Stemmer optimization: strip_suffix now works in-place on a single String buffer instead of allocating 18 new Strings per word. Note for future: reversed-suffix trie for O(suffix_len) instead of O(n_rules). - Transcript: add compaction_timestamp() for --seen display. - Agent budget configurable (default 4000 from config).
