Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Core AI

Monorepo containing Helius developer tools distributed as independent packages:

- `helius-mcp/` — MCP server (npm: `helius-mcp`) — AI-assistant agnostic
- `helius-skills/` — Standalone Claude Code skill (installed via `install.sh`)
- `helius-plugin/` — Claude Code plugin (all-in-one: bundles skill + auto-starts MCP)
- `helius-cursor/` — Cursor plugin (all-in-one: bundles skill + auto-starts MCP)
- `helius-cli/` — CLI for account setup (npm: `helius-cli`)

## Compiler-managed sync

The compiler (`npx tsx scripts/compile-skills.ts`) is the source of truth for everything generated from `helius-skills/`. It writes:

1. `helius-skills/<skill>/SKILL.md` frontmatter version (re-injected from `versions.json`) and every `helius-mcp@<version>` mention in the body
2. `.agents/skills/<skill>/` — Codex-native SKILL.md + 3 prompt variants (`openai.developer.md`, `claude.system.md`, `full.md`)
3. `helius-mcp/system-prompts/<skill>/` — same prompt variants, npm-shipped
4. `helius-plugin/skills/<dir>/references/` and `helius-plugin/skills/<dir>/SKILL.md` (refs bytewise from canonical; SKILL.md gets version re-injected)

How to install

The exact contents, by fingerprint
mdr add helius-labs/core-ai/CLAUDE.md@sha256:c25b58389119ad42

The line at the top of this page pins the label git:20261029.890f67c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
