This skill should be used when choosing "data structures", "Map vs ETS vs gb_trees performance", evaluating "hash functions", needing "HyperLogLog or bloom/cuckoo filters", or comparing OTP built-ins against specialized alternatives for Elixir
This skill should be used when code is hard to understand, a module has "too many parameters or deep nesting", "functions exceed 40 lines", "abstractions feel leaky", or evaluating "deep-module vs shallow-module" design per Ousterhout principles
This skill should be used when building "multi-node Elixir systems", choosing between "Raft and CRDTs", configuring "libcluster or Partisan", debugging "split-brain or netsplit scenarios", evaluating "CP vs AP tradeoffs", investigating "data loss" in distributed pipelines, working with "Kafka", "RabbitMQ", "Broadway", or "PubSub" message delivery guarantees, or designing "event streaming" architectures
This skill should be used when structuring Elixir code, deciding whether to use "GenServer or plain functions", "designing supervision trees", "handling overload or unbounded message queues", "organizing Phoenix contexts", or needing idiomatic OTP patterns
This skill should be used when about to run "git commit", "git push", or claim implementation is complete in an Elixir project — requires running mix precommit and confirming output before any commit or completion claim
This skill should be used when code is reported slow, before suggesting any optimization, when choosing between "cprof/eprof/fprof/tprof", or when creating "Benchee benchmarks" to compare approaches

Start with server-rendered HTML. Escalate through streams, assign_async, PubSub, and hooks only when simpler patterns can't do the job. For non-LiveView needs (APIs, mobile clients), use Plug pipelines and Channels.
| Level | Need | Pattern |
|---|---|---|
| L0 | Display data | Assigns in mount/3 |
| L1 | User interaction | phx-click, push_navigate/2 |
| L2 | Forms | to_form/2 + changeset |
| L3 | Dynamic lists | Streams (stream/3, stream_insert/4) |
| L4 | Real-time updates | PubSub, assign_async/3 |
| L5 | Browser APIs | phx-hook |
