Skill Wiki
v0.1.0 Apache-2.0 · MCP-native · open
Skill Wiki.
Skill Wiki turns each SKILL.md blob into a
wiki of typed atoms — addressable by ID, linked
by a declared edge graph, retrieved on demand. Agents see a ~3 KB
index of what exists; atom bodies stream in only when the brief
actually calls for them.
Each @scope is a Prime — a self-contained corpus on
the open Prime protocol that
powers Skill Wiki.
Why Skill Wiki
Stop bulk-loading SKILL.md files into your agent.
Three architectural inversions, each with a measurable cost saved. Read the background for the long version.
Existence ≠ content
Agents always see a ~3 KB _index.xml of what exists. Atom
bodies load only when retrieval picks them — addressed by ID, not guessed
by relevance.
Typed edges, not flat related
14 verbs (requires, validates-with,
contradicts, specializes, …) carry semantics the
parser and L3 checker reason over. The graph isn't decoration.
Three projection levels
Each atom compiles to summary (~30 tok),
core (~150 tok), full (~380 tok). Pick the
smallest projection that fits the budget.
Spec surface · v1.0 frozen
The shape of the wiki
Four numbers fixed at v1.0 of the Prime protocol — the spec the wiki is built on. They don't change when you add more Primes.

Numbers from the 6 reference Primes in this site's marketplace — compiled with the v0.1.0 reference implementation.

Flagship Prime
From the marketplace
Skill Wiki is domain-blind — actual knowledge lives in the Primes.
Each Prime is a self-contained @scope of typed atoms —
what Anthropic's SKILL.md format would look like if every
line had a type. Today's marketplace already spans design, backend
architecture, and application security.
@frontend-design is the flagship reference Prime:
898 typed atoms about visual
design — the deepest worked example of the protocol on a real domain.
@frontend-design
898 typed atoms across 9 design sub-domains — color, typography, motion, spacing, accessibility, copy voice, hierarchy, layout, and component patterns. Reference corpus + reference application: 5-tool MCP wrapper, 31 personas, 30 task taxonomies, 20-task benchmark fixtures.
