 - **Callback context** — every callback receives `ctx`; key fields: `ctx.children`, `ctx.pads`, `ctx.playback`; crash callbacks also have `ctx.crash_initiator`, `ctx.exit_reason`, `ctx.group_name`; see [Pipeline.CallbackContext](https://hexdocs.pm/membrane_core/Membrane.Pipeline.CallbackContext.md), [Bin.CallbackContext](https://hexdocs.pm/membrane_core/Membrane.Bin.CallbackContext.md), [Element.CallbackContext](https://hexdocs.pm/membrane_core/Membrane.Element.CallbackContext.md)
 - **Logging** — utilize `Membrane.Logger` instead of `Logger` in Membrane components; it prepends component path and name to log messages. Requires `require Membrane.Logger` in the module before calling any logging functions.
 - **Use `mix hex.info <plugin name>` when you need to check the newest version of a plugin**
-- **Search for appropriate plugins in [packages_list.md](../../guides/llms/packages_list.md)** before writing one — it's the canonical, LLM-tuned index of every published Membrane plugin

 - **Check input and output pad definitions of elements in `deps/` (use `cat <filename> | grep def_input_pad` and `cat <filename> | grep def_output pad`) to make sure output pad's `accepted_stream_format` is compatible with `accepted_stream_format` of the input pad which it is linked to.**
 - **If the `accepted_stream_format` doesn't match, search for an element which can act as an adapter**
 - **When constructing Membrane Pipeline, lean towards using most powerful Membrane Components, which are [Boombox.Bin](https://hexdocs.pm/boombox/llms.txt) and [Membrane.Transcoder](https://hexdocs.pm/membrane_transcoder_plugin/llms.txt), instead of using many smaller plugins**
