Declare multi-step AI methods in typed .mthds files — deterministic orchestration, structured outputs, repeatable results.
[pipe.summarize_article]
type = "PipeLLM"
inputs = { article = "Text", audience = "Text" }
output = "Text"
prompt = "Summarize $article in three bullet points for $audience."From here, Pipelex handles model routing across 60+ models, structured output parsing, and pipeline orchestration.
Install the mthds CLI, it's required by the plugin for method validation and execution:
npm install -g mthdsStart Claude Code:
claudeTell Claude to install the MTHDS plugins marketplace:
/plugin marketplace add mthds-ai/mthds-plugins
Then install the MTHDS Claude Code plugin:
/plugin install mthds@mthds-plugins
Then reload plugins:
/reload-plugins
If that doesn't work, exit Claude Code and reopen it:
/exit
Build your first method:
/mthds-build A method to summarize articles with key takeaways for different audiences
Run it:
/mthds-run
