description: "Analyze agent sessions (3 days) for MCP, hooks, skills optimization opportunities with real token stats" allowed-tools: "Bash, Agent, Read, Glob, mcp__hex-line__read_file, mcp__hex-line__grep_search, mcp__hex-line__outline"

Audit Agent Sessions

Analyze all agent sessions from the last 3 days across Claude, Codex, and Gemini. Produce actionable optimization report.

**Scope:** Multi-day batch analysis (3 days, all agents). Aggregate patterns across sessions. For single-session deep analysis: `ln-002-session-analyzer`. For skill self-audit: meta-analysis protocol §7.

**Scope:** `$ARGUMENTS` — `all` (default), `mcp`, `hooks`, `skills`, `tokens`, `problems`.

Session Storage

Agent	Path	Format
Claude	~/.claude/projects/*/*.jsonl	JSONL ({hash}.{idx}\t{json})
Codex	~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl	JSONL
Gemini	~/.gemini/tmp/*/chats/session-*.json	JSON (messages[] array)

Analysis Dimensions

Code	Dimension	Scope Filter
D1	MCP Problems & Optimization	mcp, all
D2	Built-in Operations to MCP-ify	mcp, all
D3	Hook Correctness & Efficiency	hooks, all
D4	Cross-Agent Comparison	all
D5	General Problems & Bottlenecks	problems, all
D6	Skill Extraction Opportunities	skills, all
D7	Skill Usage Analysis	skills, all
D8	Token Statistics (real numbers)	tokens, mcp, all
D9	Chronology & Trends	all, mcp, tokens

Step 1: Session Inventory

Collect session file paths into temp files for all subsequent steps. Run as single bash block.

CUTOFF=$(date -d '3 days ago' +%s)
> /tmp/audit_claude.txt; > /tmp/audit_codex.txt; > /tmp/audit_gemini.txt
C_COUNT=0; C_SIZE=0; X_COUNT=0; X_SIZE=0; G_COUNT=0; G_SIZE=0

echo "=== SESSION INVENTORY (since $(date -d @$CUTOFF +%Y-%m-%d)) ==="

echo "## Claude"

  for f in "$proj_dir"*.jsonl; do
    [ -f "$f" ] || continue
    MOD=$(stat -c %Y "$f" 2>/dev/null)
    [ -z "$MOD" ] && continue
    [ "$MOD" -lt "$CUTOFF" ] && continue
    SIZE=$(wc -c < "$f" | tr -d ' ')
    LINES=$(wc -l < "$f" | tr -d ' ')
    C_SIZE=$((C_SIZE + SIZE)); C_COUNT=$((C_COUNT + 1))
    echo "$f" >> /tmp/audit_claude.txt
