the integrations

In your stack.

Nika meets you where you work: your agent gets the plugin kit, your editor gets the live DAG, your terminal gets the binary, and they compose. Every room below is README-true: the commands are the repos' own, never invented.

31 doors · one kit · vendored at v0.111.0

The kit ships once; every client below loads it through its own door · a native marketplace, the Claude layout unported, or nika wire writing the client's real config. Proven means a live fiche: version pair plus a deterministic check line, never a claim.

add nika to ~/.kimi-code/mcp.json (mcpServers map · their two-level contract) · the legacy kimi-cli `kimi mcp add` subcommand does NOT exist in kimi-code
Kiro CLI (the Amazon Q Developer CLI rebrand)recon · nika wire kiro
add nika to ~/.kiro/settings/mcp.json (mcpServers map · the legacy ~/.aws/amazonq/mcp.json is still read, .kiro wins)

the full kit

the three lanes compose

Most people run all three. The binary does the work, the extension draws the file, the plugin teaches the agent to delegate. One sitting installs the lot.

the binary: curl -fsSL https://nika.sh/install.sh | sh
the editor: code --install-extension supernovae.nika-lang
the agent: claude plugin marketplace add supernovae-st/nika-plugins && claude plugin install nika@nika

6 lanes · one room each

Claude CodeMIT
One plugin install hands the agent the whole kit: 4 skills, 3 subagents, 6 slash commands, the read-only MCP oracle and the seatbelt hooks.
add the marketplace
claude plugin marketplace add supernovae-st/nika-plugins
CodexMIT
Codex installs the identical plugin kit from the identical repo: skills, subagents, commands, the MCP oracle.
add the marketplace
codex plugin marketplace add supernovae-st/nika-plugins
CursorMIT
Cursor takes BOTH halves: the plugin bundle (rule · skill · subagent · commands · hooks · MCP) from its marketplace, and the editor extension from Open VSX.
VS Code · Windsurf · VSCodiumMIT
A .nika.yaml file becomes a live graph: prompts on the cards, wires carrying named data, permits as chips. See the DAG before you run it.
from the cli
code --install-extension supernovae.nika-lang
Hermes · skills.sh clientsMIT
The Hermes-facing skill teaches the delegation idiom: Hermes orchestrates, Nika executes. Repeatable work leaves the chat and becomes a checkable file.

any MCP clientAGPL-3.0-or-later
The binary IS the MCP server: `nika mcp` serves 9 read-only tools: check, inspect, explain, schema, examples, template, canon, catalog, tools.

the public surfaces

8 repos · every claim README-true

the engineAGPL-3.0-or-later
The reference engine: one Rust binary that checks, prices, runs and traces workflow files.
the specApache-2.0
The language specification: nine chapters, the JSON Schema, the canon counts, the template pack, the conformance suite.
the registryApache-2.0
The npm-of-workflows: share workflow files as verified, content-pinned entries.
the TypeScript clientMIT
A typed, zero-dependency TS client: drive the shipped binary today, target the future serve API without pretending.
the site-audit, archivedApache-2.0
A full SEO + GEO site audit as ONE workflow file: discover, crawl bounded, score deterministically, one narrated verdict. Archived on 2026-07-29 and kept public as evidence that a workflow ran at real scale against real websites.
the docsMIT
The task-oriented documentation, built by Mintlify from a public source repo.
the tapMIT
The official Homebrew tap, tracking the latest tagged release.
this siteMIT
nika.sh itself: every page a projection of pinned sources, every count derived, every claim re-proven in CI.
