statspai
Agent-native one-stop toolkit for the full empirical data-analysis pipeline in Python (v1.6+). 390+ functions, one import (`import statspai as sp`), unified API. Covers the complete loop after data cleaning — descriptive stats & EDA (sp.sumstats, sp.balance_table, sp.balance_pane
alspec
Create a technical specification (spec) for a feature or task.
alreview
Write a code review report comparing the current branch to a base branch.
alread
Read all specs and summaries in the current task directory to prepare context.
alplan
Create implementation plan(s) from a technical specification.
alignfirst
Collaborative problem-solving protocols. Write technical specifications (spec, or alspec), create implementation plans (plan, or alplan), or use Align-and-Do Protocol (AAD). Also generates PR/MR descriptions (aldescription) and code review reports (alreview).
alignfirst-coaching
Coach an AlignFirst spec-plan-execute or AAD workflow using a CLI wrapper around the claude command. Use when orchestrating coding agents through AlignFirst protocols non-interactively.
aldescription
Write a description summarizing implemented work. Generates PR/MR descriptions from completed changes.
al
Align-and-Do Protocol (AAD). Use for smaller tasks that don't need formal specs or plans.
langfuse
