Change risk analysis — detect blast radius, risk score, and breaking changes from git diffs. Use before any PR or merge. Crown jewel: detect_changes_tool. Triggers on: "review PR", "check impact", "blast radius", "what breaks", "safe to merge"

Structural change safety gate. Builds a SHA-256 AST graph from source code, then on any diff computes:
| Question | Tool |
|---|---|
| Is this change safe to ship? | mcp__code-review-graph__detect_changes_tool(base_branch="main") |
| Build/rebuild the graph | mcp__code-review-graph__build_graph_tool(repo_path=".") |
| Graph status + stats | mcp__code-review-graph__get_graph_info_tool |
| What changed vs main? | mcp__code-review-graph__get_diff_tool(base_branch="main") |
| Node details | mcp__code-review-graph__get_node_tool(node_id="<id>") |
| Node neighbors | mcp__code-review-graph__get_neighbors_tool(node_id="<id>", depth=2) |
| Find by name | mcp__code-review-graph__search_nodes_tool(query="AuthService") |
| Community structure | mcp__code-review-graph__get_communities_tool |
| Critical path | mcp__code-review-graph__get_critical_path_tool(source="<id>", target="<id>") |
| Dependency chain | mcp__code-review-graph__get_dependency_chain_tool(node_id="<id>") |

First build: build_graph_tool(repo_path=".") — ~6s for 500 files, ~30s for large repos.
Incremental: git post-commit hook runs code-review-graph update automatically. <2s on any commit.
After major refactor: build_graph_tool(repo_path=".", force_rebuild=True) — forces full re-index.
MCP server: Started automatically by Claude Code when mcp__code-review-graph__* tools are invoked.
Started via uvx code-review-graph serve — isolated environment, no PATH issues.

Route a codebase question to the right tool — structural graph, semantic search, or risk analysis. Use when you need to find or understand code without knowing exact file names.

Auto-configure CLAUDE.md and claude/ knowledge docs for a new project. Use when setting up Brain Bootstrap in a new repository. Discovers the codebase, fills in templates, and writes project-specific configuration.

Use before any new feature, component, or behavioral change — when you need to explore requirements and design before writing code

Activate safety guards for the session. Use /careful before critical operations — blocks rm -rf, DROP TABLE, git push --force, kubectl delete namespace, docker system prune via PreToolUse hook.

Generate a user-facing changelog from git commits — categorize, filter noise, translate to user language. Runs in isolated fork context.

Save session state before context gets full or before ending. Writes current task state, branch, and loaded docs to claude/tasks/todo.md so the next session can resume cleanly.
