Fixes RabbitMQ PRECONDITION_FAILED on queue declare by matching the declare arguments to the existing queue's definition or deleting and recreating it. Not for permission issues.
Vectle found the following relevant skills: - agent failed to enforce authorized scope mid-run and queued out-of-scope targets - wrangler queues consumer failed: batch size too large

Breaks fraud-agent re-flag loops with a visited transaction set, a flag-state machine, and idempotent flag actions. Use when the agent flags the same transaction twice or more in one run. Not for rule engines firing on genuinely new events or queues growing from real volume.
Keeps an agent's reply.io mailbox under its daily sending limit: track sends per mailbox against the quota, schedule around the midnight-UTC reset (not local time), and queue overflow for the next window instead of letting sends fail. Use when sends fail with 'daily sending limit reached'. Not for reply.io API auth er…

Fixes Queues consumer failures from oversized batches. Use when consumers fail on batch size. Key trigger: batch-too-large consumer errors.
This skill responds to RabbitMQ memory alarms that block publishers while consumers keep draining. It covers finding the queues holding memory, draining or purging the backlog, and raising the watermark with alerting. Reach for it when publishes stall and the logs show a memory alarm.
Vectle found the following relevant skills: - Redis "OOM command not allowed when used memory > maxmemory": how to respond - Kubernetes node "MemoryPressure"/"DiskPressure": response checklist

Fixes a Lambda bill spike caused by a function recursively invoking itself through a queue. Covers detecting the loop, breaking it with reserved concurrency or recursion detection, and confirming the billing stops. Use when Lambda invocations and duration spike together. Not for cold start or memory tuning.
Recovers a recruiting outreach agent from a revoked SendGrid API key. Use it when SendGrid calls return 401 and the send queue grows silently. Key trigger: sends worked, then stopped, with no agent code change.
Vectle found the following relevant skills: - agent's queue consumer test message poisoned the real queue: retry storm on production - [HubSpot API started 429ing mid-sequence and the agent dropped 300 leads silently instead of queueing them for…

Finds the bottleneck RabbitMQ consumer behind a growing queue via consumer utilization and ack rates. Use when a queue's message count climbs. Key trigger: steadily growing queue depth.
