sw/analytics

Tool-Use Rationale

• Read: Load metrics snapshots, increment history, and config to compute analytics.
• Bash: Run specweave metrics CLI commands to gather live telemetry data.

Usage

sw:analytics [--cache-stats] [--spawn-count] [--token-usage]

--cache-stats

Displays prompt cache hit rates per skill for the current session.

Output format:

Cache Statistics (current session)
───────────────────────────────────
sw/grill         hit rate: 78% (1,240 tokens from cache)
sw/judge-llm     hit rate: 65% (980 tokens from cache)
sw/code-reviewer hit rate: 82% (1,560 tokens from cache)
───────────────────────────────────
Overall:         hit rate: 75%

Requirements:

• Cache must be enabled (cache.staticContextFiles non-empty in config)
• Minimum 2 invocations per skill for meaningful hit rate

Enable persistent metrics: Set analytics.cacheMetrics.enabled: true in .specweave/config.json.

--spawn-count

Reports agent spawn counts per team session. Use to verify that Opus 4.7 fan-out reduction is working (target: ≤ 50% of pre-1.1.0 baseline).

--token-usage

Reports total token consumption per skill across the session.
