Skill Tree
A skill tree is a structured map of the smaller skills or topics that make up a larger skill, arranged so it's clear what to learn first and what depends on what — turning a vague goal like "learn Spanish" into a concrete, ordered set of things to actually work through.
Definition
The name comes from the branching diagrams used in games and technical curricula: a root skill (or topic) branches into sub-skills, and some nodes can't be started until an earlier one is reasonably solid. Unlike a flat checklist, a skill tree encodes dependency and structure — it shows not just what to learn, but in what order it makes sense to learn it.
Why It Matters
Self-directed learning usually fails at the planning stage, not the effort stage — people are willing to put in the hours but don't know what to work on next, so time goes to whatever resource they found most recently rather than what would actually move them forward. A skill tree turns "I should get better at X" into a specific next node to work on, with visible progress underneath it.
How It Works
Each node in a tree represents one learnable chunk — small enough to make real progress on in a session or two, specific enough to know when it's done. Nodes can have prerequisites (an earlier node that should be reasonably complete first) and, once mastery criteria are attached to a node, a way to say when it counts as actually learned rather than just visited.
Example
A "Web Development" tree might branch into HTML/CSS, JavaScript fundamentals, and a framework — with the framework node locked until JavaScript fundamentals is far enough along, so the learner isn't trying to learn React before they can read a for-loop.
Common Mistakes
Building a tree that's too shallow (three giant nodes like "Frontend," "Backend," "Deploy" — each one is really a whole tree of its own) makes progress invisible for weeks at a time. Building one that's too granular has the opposite problem: dozens of tiny nodes that turn learning into checkbox-chasing instead of skill-building.
How RodionSkill Uses Skill Tree
Skill Trees are a first-class structure in RodionSkill, each node trackable against real Focus Sessions and optional Mastery criteria, with a Next Action always resolvable to the first unlocked, incomplete node — and a tree can be linked to a Subject so a Subject's own progress view aggregates across every tree feeding into it.
