Claude-mem 12.0 introduced smarter code exploration and a file-read decision gate, then 12.0.1 hotfixed a Bun-only import that broke Node-based MCP clients.
The 12.0 release adds a file-read decision gate that injects prior observations and blocks redundant Reads/Edits to cut token waste, plus a 24-language AST "smart-explore" powered by tree-sitter, and platform-scoped session isolation via a new column. Details are in the notes for v12.0.0.
A bad bundle in 12.0.0 pulled bun:sqlite into the Node MCP server, crashing MCP-only clients. The v12.0.1 hotfix extracts a lightweight worker spawner, improves Bun detection, and adds build guardrails (ban require("bun:*"), size budget).
Separately, LangChain pushed a small core update fixing symlink handling in a deprecated prompt path langchain-core 1.2.27.
Token-saving file gating and AST smart-explore can reduce model spend and improve code navigation across many languages.
12.0.1 unblocks Node-based MCP clients and bakes in guardrails to avoid similar build breakage.
-
terminal
Upgrade to 12.0.1 and run MCP JSON-RPC initialize/tools/list/tools/call under Node; verify the worker spawns via Bun and no bun:* leaks.
-
terminal
Measure token deltas on repeated Reads/Edits to confirm the decision gate suppresses redundant file access; validate session isolation and DB migration for platform_source.
Legacy codebase integration strategies...
- 01.
If you touched 12.0.0, move to 12.0.1 now; ensure Bun is installed and on PATH for MCP flows running under Node.
- 02.
Review custom MCP plugins/bundles for accidental bun:* imports; test DB queries and dashboards after the platform_source session namespacing change.
Fresh architecture paradigms...
- 01.
Adopt smart-explore for multi-language repos; tree-sitter grammars are user-installable to cover your stack from day one.
- 02.
Design multi-tool setups with platform-scoped sessions to avoid cross-contamination between Claude, Codex, and others.
