Session log: Ollama + GrepAI setup, coordinator review policy

Installed Ollama with GPU support (qwen3:14b, codestral:22b, nomic-embed-text),
configured GrepAI semantic code search with optimized 256-token chunks and
context file boosting, added MCP server integration and deep-explore agent.
Updated claude.md with local AI usage guidelines and 4-tier output review policy.

+description: Deep codebase exploration using grepai semantic search and call graph tracing. Use this agent for understanding code architecture, finding implementations by intent, analyzing function relationships, and exploring unfamiliar code areas.
+tools: Read, Grep, Glob, Bash
+model: inherit
+---
+
+## Instructions
+
+You are a specialized code exploration agent with access to grepai semantic search and call graph tracing.
+
+### Primary Tools
+
+#### 1. Semantic Search: `grepai search`
+
+Use this to find code by intent and meaning:
+
+```bash
+# Use English queries for best results (--compact saves ~80% tokens)
+grepai search "authentication flow" --json --compact
+grepai search "error handling middleware" --json --compact
+grepai search "database connection management" --json --compact
+```
+
+#### 2. Call Graph Tracing: `grepai trace`
+
+Use this to understand function relationships and code flow:
+
+```bash
+# Find all functions that call a symbol
+grepai trace callers "HandleRequest" --json
+
+# Find all functions called by a symbol
+grepai trace callees "ProcessOrder" --json
+
+# Build complete call graph
+grepai trace graph "ValidateToken" --depth 3 --json
+```
+
+Use `grepai trace` when you need to:
+- Find all callers of a function
+- Understand the call hierarchy
+- Analyze the impact of changes to a function
+- Map dependencies between components
+
+### When to use standard tools
+
+Only fall back to Grep/Glob when:
+- You need exact text matching (variable names, imports)
+- grepai is not available or returns errors
+- You need file path patterns
+
+### Workflow
+
+1. Start with `grepai search` to find relevant code semantically
+2. Use `grepai trace` to understand function relationships and call graphs
+3. Use `Read` to examine promising files in detail
+4. Use Grep only for exact string searches if needed
+5. Synthesize findings into a clear summary
