Give any agent new powers
Rune is a curated library, not an open marketplace. Each rune is a single skill that hands your agent a capability it didn't have — and every one is forged, end to end, by Fable 5.
11 runes. One author.
The library opens small and grows deliberately. Read exactly what each rune grants before you install it — no surprises.
11 runes, forged by Fable 5
TypeScript Mastery
The complete TypeScript doctrine — strictness, narrowing, generics, type-level craft, runtime boundaries — in one rune.
Rust Mastery
Expert Rust where speed and safety reinforce each other — ownership, allocation discipline, profiling, fearless concurrency, disciplined unsafe.
React Mastery
The complete React doctrine — architecture, state, effects, performance, testing — in one rune.
Web Security
Defensive security doctrine — auth, injection, SSRF, secrets — for code that survives contact with the internet.
Frontend Aesthetics
Design taste as doctrine — direction, typography, color, atmosphere, and the anti-AI-slop catalog.
Game Design
Design judgment for games — core loops, meaningful choices, balance, difficulty, juice — engine-agnostic doctrine.
Web Games
Browser games done right — fixed-timestep loops, Phaser, canvas, collision, input feel, juice, and shipping to itch.
Bevy Mastery
The Rust ECS engine, mastered — world-as-database thinking, plugins, schedules, Avian physics, and surviving Bevy's release cadence.
Multiplayer Netcode
The art of hiding the speed of light — rollback, prediction, lag compensation, and servers that trust nobody.
Testing Doctrine
Tests that let you change code without fear — strategy, mocking discipline, Playwright, and the war on flakes.
Three.js Mastery
Complete 3D doctrine — scenes, PBR, glTF, shaders (GLSL + TSL), WebGPU, and react-three-fiber — in one rune.
Most marketplaces optimise for how many. Rune optimises for how good.
One voice, all the way down
The same hand forges every rune. Conventions, tone, and quality don't drift between the first rune and the fiftieth.
Curation over volume
Not every power is worth granting. Each rune earns its place in the library, or it never ships.
Maintained, not abandoned
Every rune has an owner who still cares. Updates land together and deliberately — never at random.
No CLI to install. Just add a rune.
Every rune is plain files. One command writes it straight into your agent's skills folder — Claude Code, Codex, or both, project-local or global, your call. Run it with whichever package manager you already have; nothing left behind.
