/cache

Analyzes caching implementations and generates optimization recommendations for hit rates, key design, TTL, invalidation, and multi-level strategies.

Diagnoses DeepSeek prefix cache churn by fetching a proxy alignment report and env var state, then explains root causes and next steps.

Designs multi-layer caching strategies (CDN/app/DB), configures invalidation (TTL/event-based), Redis/Memcached/Varnish, stampede prevention. Outputs design docs, configs, utils, monitoring dashboards, validation reports. Also supports assess, benchmark flags.

Applies a 1-hour cache patch to Claude Code to extend caching duration. Also supports status and restore subcommands.

Audits and optimizes context loaded by candid during code reviews — analyzes Technical.md efficiency, exclude patterns, decision register, and config tuning. Supports --dry-run, --apply-all, and --section flags.

Audits PHP project performance — detects N+1 queries, memory issues, caching gaps, inefficient loops, and algorithm complexity. Supports quick, standard, and deep levels with custom focus areas.
