— name: redis-inspect description: Inspect Redis cache keys, values, and TTLs for debugging. Supports both main cache and system cache. Use for debugging cache issues, checking cached values, and monitoring cache state. Read-only by default. — # Redis Cache Inspector Use this skill to inspect Redis cache state for debugging purposes. ## Running Commands “`bash node .claude/skills/redis-inspect/query.mjs <command> [options] “` ### Commands | Command | Description | |———|————-| | `get <key>` | Get a string value | | `keys <pattern>` | Find keys matching pattern (use * as wildcard) | | `ttl <key>` | Get TTL (-1 = no expiry, -2 = not found) | | `type <key>` | Get the type of a key | | `exists <key>` | Check if key exists | | `hgetall <key>` | Get all fields from a hash | | `hget <key> <field>` | Get a specific hash field | | `scard <key>` | Get set cardinality (count) | | `smembers <key>` | Get all set members | | `llen <key>` | Get list length | | `lrange <key>` | Get list elements | | `del <key>` | Delete a key (requires –writable) | | `info` | Get Redis server info | ### Options | Flag | Description | |——|————-| | `–sys` | Use system cache instead of main cache | | `–writable` | Allow write operations (required for del) | | `–json` | Output raw JSON | | `–limit <n>` | Limit results (default: 100) | ## Cache Types The project has two Redis instances: | Cache | Flag | Env Variable | Purpose | |——-|——|————–|———| | **Main Cache** | (default) | `REDIS_URL` | Regular cache, cluster mode, can be lost | | **System Cache** | `–sys` | `REDIS_SYS_URL` | Persistent system values, single node | ### Main Cache (default) Regular application cache. Data here can be regenerated if lost. – User sessions – Cached queries – Temporary data – Rate limiting counters ### System Cache (–sys) Persistent system configuration and state. More critical data. – Feature flags – Generation limits/status – System permissions – Job state – Event configurations ## Examples “`bash # Find keys matching a pattern node .claude/skills/redis-inspect/query.mjs keys "user:*" –limit 20 node .claude/skills/redis-inspect/query.mjs keys "packed:caches:*" # Get a value node .claude/skills/redis-inspect/query.mjs get "session:data2:123456" # Check system cache values node .claude/skills/redis-inspect/query.mjs –sys get "system:features" node .claude/skills/redis-inspect/query.mjs –sys hgetall "system:entity-moderation" # Check TTL node .claude/skills/redis-inspect/query.mjs ttl "generation:count:123" # Inspect a hash node .claude/skills/redis-inspect/query.mjs hgetall "packed:caches:cosmetics" node .claude/skills/redis-inspect/query.mjs hget "system:entity-moderation" "entities" # Check set size node .claude/skills/redis-inspect/query.mjs scard "queues:seen-images" # Get server info node .claude/skills/redis-inspect/query.mjs info node .claude/skills/redis-inspect/query.mjs –sys info “` ## Common Key Patterns ### Main Cache | Pattern | Description | |———|————-| | `user:*` | User data | | `session:*` | Session data | | `packed:caches:*` | Packed/compressed cached data | | `packed:user:*` | Packed user cache | | `generation:*` | Generation-related cache | | `tag:*` | Tag cache | ### System Cache | Pattern | Description | |———|————-| | `system:*` | System configuration | | `generation:*` | Generation limits/status | | `download:limits` | Download limits | | `job:*` | Job state | | `event:*` | Event configurations | | `new-order:*` | New Order game state | | `daily-challenge:*` | Daily challenge config | ## Debugging Tips “`bash # Check if a user's session exists node .claude/skills/redis-inspect/query.mjs keys "session:data2:*" –limit 10 # Check generation status node .claude/skills/redis-inspect/query.mjs –sys get "generation:status" # Check feature flags node .claude/skills/redis-inspect/query.mjs –sys hgetall "system:features" # Check cache memory usage node .claude/skills/redis-inspect/query.mjs info “` ## Write Operations Write operations require `–writable` flag and user approval: “`bash # Delete a specific key (requires approval) node .claude/skills/redis-inspect/query.mjs del "some:key" –writable “` **IMPORTANT**: Always ask the user for permission before using `–writable`.
