feat: shrink default tool surface + cap memory files#39
Merged
Conversation
Split staticTools into coreTools (always on) and opt-in groups via MAX_TOOLS_BROWSER / LINKEDIN / IOS / LAUNCHPAD / SUBAGENT env flags (or MAX_TOOLS_ALL for legacy behavior). Tool schemas ship on every request, so this cuts baseline input tokens meaningfully when only core tools are needed. Also cap each memory file at MAX_MEMORY_FILE_CHARS (default 20K) with a warn log so an unbounded MEMORY.md or daily log can no longer silently bloat the system prompt.

Summary
coreTools(fs, shell, ssh, nix-relay, gpu) stay on by default;BROWSER/LINKEDIN/IOS/LAUNCHPAD/SUBAGENTgroups are now opt-in viaMAX_TOOLS_<GROUP>=true(orMAX_TOOLS_ALL=truefor the old behavior). Tool schemas ship on every request, so this cuts baseline input tokens meaningfully when those groups aren't needed.MAX_MEMORY_FILE_CHARS(default 20K) inloadMemory, with a warn log and a visible truncation marker, so an unboundedMEMORY.mdor daily log can't silently bloat the system prompt.Part of the context-optimization series — see also #(PR1 ctx-ignore), #(PR3 lower compaction threshold), #(PR2 per-tool caps + stale pruning). PR 4 (Mux prompt caching) is next, in the
