Checking that the SKILL.md file is still in the repository.

Read and write to Upstash Redis-compatible key-value store via REST API. Use when there is a need to save or retrieve key-value data, use Redis features (caching, counters, lists, sets, hashes, sorted sets, etc.) for the current interaction, or when the user explicitly asks to use Upstash or Redis.

Upstash Redis Key-Value Store

Interact with Upstash's Redis-compatible key-value store using the REST interface.

Script Location

bash

bun run scripts/upstash-client.ts <command> [args...]

IMPORTANT: Always run with bun run, not directly.

Configuration

Environment Variables

The script uses these environment variables by default:

UPSTASH_REDIS_REST_URL - The Upstash REST API URL
UPSTASH_REDIS_REST_TOKEN - The Upstash REST API token

Overriding Credentials

If the user provides credentials from another source (conversation context, a file, etc.), use the --url and --token flags to override environment variables:

bash

bun run scripts/upstash-client.ts --url "https://..." --token "AX..." GET mykey

Priority: Command-line flags > Environment variables

Command Reference

Hashes store field-value pairs. Pass fields and values as alternating arguments:

bash

# Set hash fields (field/value pairs)
HSET <key> <field1> <val1> [field2 val2...]
HSETNX <key> <field> <value>           # Set field if not exists

bash

# Push elements

# Pop elements
LPOP <key> [count]
RPOP <key> [count]
 
# Access elements
LRANGE <key> <start> <stop>            # Get range (0 = first, -1 = last)
LLEN <key>
LINDEX <key> <index>
 
# Modify
LSET <key> <index> <value>
LREM <key> <count> <value>             # Remove count occurrences

SADD <key> <member1> [member2...]
SREM <key> <member1> [member2...]
 
# Query
SMEMBERS <key>
SISMEMBER <key> <member>

Confirmation Behaviour

Default: Ask for Confirmation

Before executing any destructive operation (write, modify, or delete), you MUST ask the user for confirmation. This includes:

Write operations:

SET, SETNX, SETEX, PSETEX, MSET, MSETNX
HSET, HSETNX
LPUSH, RPUSH, LPUSHX, RPUSHX, LSET, LINSERT
SADD
ZADD

Modify operations:

INCR, INCRBY, INCRBYFLOAT, DECR, DECRBY
APPEND, SETRANGE
HINCRBY, HINCRBYFLOAT
LREM, LTRIM, LMOVE
ZINCRBY

Delete operations:

DEL, UNLINK
HDEL
LPOP, RPOP
SREM, SPOP, SMOVE
ZREM, ZREMRANGEBYRANK, ZREMRANGEBYSCORE, ZPOPMIN, ZPOPMAX
FLUSHDB, FLUSHALL (extra caution)

TTL/Rename operations:

EXPIRE, EXPIREAT, PEXPIRE, PEXPIREAT, PERSIST
RENAME, RENAMENX

Example confirmation prompt:

"I'm about to HSET user:1 with fields {name: "John", email: "john@example.com"}. Proceed?"

YOLO Mode: Skip Confirmation

If the user indicates they do not want to be asked for confirmation, respect this for all subsequent operations. Indicators include:

"YOLO mode"
"Don't ask for confirmation"
"You're free to make changes without asking"
"Just do it"
"No need to confirm"
"Auto-approve" or "auto-confirm"
Any similar phrasing indicating blanket approval

Once YOLO mode is activated, proceed with destructive operations without asking, but still inform the user what was done.

Example:

Set user:1 with {name: "John", email: "john@example.com"} - done.

Error Handling

If credentials are missing or invalid, the script will exit with an error message. Ensure the user has configured either:

Environment variables (UPSTASH_REDIS_REST_URL, UPSTASH_REDIS_REST_TOKEN)
Or provides credentials via --url and --token flags

When to Use This Skill
