What's New

detect_changes tool (NEW)

Map uncommitted git changes to affected graph symbols and their blast radius with risk classification. Supports multiple scopes:

• unstaged — working directory changes
• staged — staged changes only
• all (default) — both staged and unstaged
• branch — diff against a base branch (e.g. main)

Returns changed files, changed symbols, impacted callers with risk scores, and an impact summary.

Risk scoring on trace_call_path

New risk_labels=true parameter adds depth-based impact classification to call chain traces:

• CRITICAL (hop 1) — direct callers/callees, will break
• HIGH (hop 2) — indirect, likely affected
• MEDIUM (hop 3) — may be affected
• LOW (hop 4+) — unlikely but possible

Includes impact_summary with counts per risk tier and has_cross_service flag.

Wider editor support

codebase-memory-mcp install now auto-registers MCP config for:

• Cursor (~/.cursor/mcp.json)
• Windsurf (~/.codeium/windsurf/mcp_config.json)

In addition to existing Claude Code and Codex CLI support. uninstall cleans up all editors.

MCP SDK upgrade

Upgraded go-sdk from v1.3.1 to v1.4.0 — includes security fixes and MCP spec compliance improvements.

Improved tool descriptions

Inline regex examples on search parameters help AI agents craft precise single-query searches.

Tool Count

14 tools (was 13). Only 1 new tool added (detect_changes), 1 existing tool extended (trace_call_path + risk_labels).

Performance

Zero indexing overhead. Risk scoring is pure post-processing on existing BFS results. detect_changes runs git at tool-call time only — no new pipeline passes or storage.
