Why Rune?

Most skill ecosystems are either too many isolated skills (540+ that don't talk to each other) or rigid pipelines (A → B → C, if B fails everything stops).

Rune is a mesh — 61 skills with 200+ connections across a 5-layer architecture. Skills call each other bidirectionally, forming resilient workflows that adapt when things go wrong.

Pipeline:  A → B → C → D         (B fails = stuck)
Hub-Spoke: A → HUB → C           (HUB fails = stuck)
Mesh:      A ↔ B ↔ C             (B fails = A reaches C via D→E)
           ↕       ↕
           D ↔ E ↔ F

Benchmark: With Rune vs Without Rune

We ran 10 standardized coding tasks on Claude Code — once without Rune (vanilla), once with Rune — and measured tokens, cost, duration, and correctness.

Headline Results

                Without Rune    With Rune     Delta
Avg Tokens:     541,400         454,491       ↓ 16%
Avg Cost:       $0.69           $0.65         ↓ 6%
Avg Duration:   2.3 min         2.1 min       ↓ 9%
Avg Tool Calls: 14              13            ↓ 7%

Where Rune Shines: Complex Tasks

Task	Difficulty	Tokens	Cost	Duration	Tools
Refactor 450-line component	Medium	-62%	-17%	-32%	-27%
Full feature (auth + API + tests)	Complex	-36%	-29%	-31%	-27%
Add Zod validation	Easy	-9%	-28%	-32%	0%
Dark mode across 6 components	Hard	~0%	+10%	-7%	-6%

Rune doesn't make Claude smarter — Claude already knows how to code. Rune makes Claude disciplined. The more complex the task, the more discipline matters.

"Without Rune, Claude writes code that works. With Rune, Claude writes code that lasts."
