AILANG Bootstrap

Quick start package for using AILANG with Claude Code and OpenAI Codex.

AILANG is a deterministic programming language designed for AI code synthesis and reasoning.

Installation

Install the AILANG CLI before installing either agent integration:

curl -fsSL https://ailang.sunholo.com/install.sh | bash
ailang --version

The plugins invoke the local ailang executable, so it must be available on PATH.

Claude Code

# Step 1: Add the marketplace
/plugin marketplace add sunholo-data/ailang_bootstrap

# Step 2: Install the plugin
/plugin install ailang@sunholo-data/ailang_bootstrap

Or clone and add locally:

git clone https://github.com/sunholo-data/ailang_bootstrap
/plugin marketplace add ./ailang_bootstrap
/plugin install ailang@ailang_bootstrap

OpenAI Codex

Codex requires Node.js 18 or newer for the local MCP server:

node --version
codex plugin marketplace add sunholo-data/ailang_bootstrap --ref stable
codex plugin add ailang@ailang-marketplace
codex plugin list

Start a new Codex session after installation. Alternatively, add the marketplace with the CLI, then install AILANG through /plugins or the Codex desktop Plugins directory.

Codex loads the shared skills and five local MCP tools: ailang_prompt, ailang_check, ailang_run, ailang_builtins, and ailang_eval.

Manual Installation

Download a platform-specific release from GitHub Releases:

PlatformArchitectureAsset
macOSApple Silicondarwin.arm64.ailang-bootstrap.tar.gz
macOSInteldarwin.x64.ailang-bootstrap.tar.gz
Linuxx64linux.x64.ailang-bootstrap.tar.gz
Windowsx64win32.x64.ailang-bootstrap.zip

Each release includes the AILANG binary pre-bundled.

What's Included

Skills

SkillPurpose
ailangWrite, run, and develop with AILANG
ailang-inboxCross-agent messaging with semantic search, deduplication, and GitHub sync

Slash Commands (Claude Code)

CommandPurpose
/ailang-promptLoad syntax teaching prompt (do this first!)
/ailang-run <file>Run an AILANG program
/ailang-check <file>Type-check without running
/ailang-new <name> [template]Create new program from template
/ailang-replStart interactive REPL
/ailang-builtins [search]List builtin functions
/ailang-editor <editor>Install syntax highlighting

Hooks (Claude Code)

HookEventPurpose
session_start.shSessionStartInbox check + brain context
brain_session.shSessionStartInject relevant brain knowledge
git_guard.shPreToolUse(Bash)Block destructive git ops
microrag_context.shPreToolUse(Edit\Write\Read\MultiEdit)JIT μRAG knowledge injection — surfaces AILANG syntax/builtin docs at tool-call time
microrag_lint.shPostToolUse(Edit\Write\MultiEdit)First-use builtin nudge for *.ail edits
brain_resolution.shPostToolUse(Bash)Capture command resolutions
observatory_hook.shAll eventsOTEL telemetry for AILANG Observatory

Disable μRAG: export AILANG_MICRORAG_ENABLED=0. Requires ailang and jq on PATH; degrades silently if either is missing.

μRAG brain corpus auto-bootstrap: install.sh runs ailang micro-rag init && ailang micro-rag bootstrap --scope user --no-embed after the binary lands. This populates the brain DB at ~/.ailang/state/brain.db with the ailang-syntax (~50 frames) and ailang-builtins (~280 frames) namespaces using only resources embedded in the binary — no source repo required. Works on Windows / minimal Docker images / anywhere awk and python3 are absent.

Re-run manually after install.sh to upgrade the corpus to embedding-backed retrieval (requires Ollama):

ailang micro-rag bootstrap --scope user           # add embeddings on top of SimHash/FTS
ailang micro-rag bootstrap --scope user --reset   # full rebuild (use after AILANG version bump)

AILANG lens (Claude Code mod, optional)

A live pane that shows what you're writing as AILANG sees it. After every Edit/Write of a .ail file it runs ailang iface and ailang check and draws the module's functions, their types and effect rows (pure or !{IO,FS}), plus any type errors — keeping the last good signatures on screen beside a broken edit. The status line carries a one-line summary.

/plugin install ailang-lens@ailang-marketplace
/reload-plugins
/ail-lens [file.ail]     # open the pane, or analyse any file into it

Mods are an early-access Claude Code feature; where they are not enabled the plugin installs but does nothing. Requires ailang on PATH.

MCP Servers (TWO complementary servers)

1. Local stdio MCP (auto-installed by this plugin) — wraps the local AILANG CLI for actually running/checking code:

  • ailang_check - Type-check files
  • ailang_run - Run programs
  • ailang_prompt - Get teaching prompt (embedded copy)
  • ailang_builtins - List builtins
  • ailang_eval - Evaluate an expression in the non-interactive REPL

2. Remote HTTP MCP at mcp.ailang.sunholo.com — version-locked live docs, stdlib, examples, design docs, benchmarks. Available to any agent harness that supports remote MCP (Claude Desktop, Cursor, Cline, Continue, Claude Code).

{
  "mcpServers": {
    "ailang-docs": {
      "url": "https://mcp.ailang.sunholo.com/mcp/",
      "transport": "streamable-http"
    }
  }
}

Tools include prompt_get, stdlib_modules, stdlib_search, examples_for_concept, limitations_list, effects_catalog, and submit_feedback (for filing AILANG bugs from inside an agent session). Use these to avoid stale embedded knowledge — the snapshot is rebuilt and redeployed on every AILANG release.

See docs/guides/agent-mcp for the full tool catalog.

Quick Start

Once installed, you can:

# CRITICAL: Load syntax before writing code
ailang prompt

# Run AILANG code
ailang run --caps IO --entry main program.ail

# Start interactive REPL
ailang repl

# Type-check without running
ailang check program.ail

Example AILANG Program

module myproject/hello

export func main() -> () ! {IO} {
  print("Hello, AILANG!")
}

Run with:

ailang run --caps IO --entry main hello.ail

Key Syntax Rules

  1. Use func - NOT fn, function, or def
  2. Semicolons between statements - let x = 1; let y = 2; x + y
  3. Pattern matching uses => - NOT : or ->
  4. No loops - Use recursion instead
  5. print expects string - Use print(show(42)) for numbers
