Sage is an AI skills framework for Claude Code that enforces a four-phase UNDERSTAND→ENVISION→DELIVER→REFLECT pipeline with chained workflows so teams can deliver structured outcomes with gap detection and quality gates.
About
Sage is an intelligent skills framework for Claude Code that makes AI agents think before they act through a four-phase pipeline: UNDERSTAND, ENVISION, DELIVER, and REFLECT. It ships 14 workflows, 37 skills, and five agent personas with deterministic routing, gap detection, and multi-layer quality enforcement. Developers reach for it when they want process discipline across research, design, implementation, and retrospective learning rather than jumping straight from request to code.
- Four-phase pipeline: UNDERSTAND, ENVISION, DELIVER, REFLECT
- 14 workflows chaining 37 skills with 5 agent personas
- Deterministic keyword routing plus sub-agent classifier
- Gap detection warns before building without research
- Quality gates with deterministic scripts and sub-agent reviews
Sage by the numbers

How do I keep Claude Code from skipping research, design, and review when moving from vague requests to shipped features?
Route requests through UNDERSTAND→ENVISION→DELIVER→REFLECT workflows with 37 skills, gap detection, and quality gates.
Who is it for?
Product and engineering teams who want enforced multi-phase workflows with 37 skills, navigator routing, and retrospective learning in Claude Code.
Skip if: Developers who want minimal process overhead or a single-purpose coding skill without structured phase transitions.
What you get
Produces phase-appropriate artifacts such as research maps, UX specs, implementation plans, review findings, and reflection learnings seeded into the next cycle.

FAQ
What phases does Sage use?
UNDERSTAND for research and analysis, ENVISION for design and architecture, DELIVER for build/fix/review/QA, and REFLECT for cycle review and learnings.
How does routing work?
Keywords match instantly to workflows; when unclear, a sub-agent classifier picks the phase and the user confirms before skills run.
How many skills and workflows are included?
The manifest describes 14 workflows, 37 skills, and 5 agent personas with process enforcement across the full pipeline.
