From ffb0b7c8407c55b3e691c5b5f61f182e379a3e4e Mon Sep 17 00:00:00 2001 From: steveluc Date: Thu, 22 Jan 2026 14:34:49 -0800 Subject: [PATCH 01/15] Add VS Code extension for Action Grammar (.agr) syntax highlighting Created a VS Code extension that provides comprehensive syntax highlighting for Action Grammar files used in TypeAgent. Features: - Rule definition highlighting (@ = ...) - Rule reference highlighting () - Capture syntax highlighting ($(name:Type) and $(name)) - Action object highlighting with embedded JavaScript syntax (-> { }) - Operator highlighting (|, ?, *, +) - Comment support (//) - String literal highlighting - Bracket matching and auto-closing pairs - Language configuration for editor features File structure: - package.json: Extension manifest with language contributions - language-configuration.json: Editor behavior configuration - syntaxes/agr.tmLanguage.json: TextMate grammar definition - README.md: Installation and usage documentation - OVERVIEW.md: Technical implementation details - sample.agr: Sample file demonstrating all syntax features - LICENSE: MIT license The extension uses TextMate grammar for syntax highlighting and follows VS Code extension best practices.

Outputs a complete .agr file ready for use in TypeAgent Key features: - Automatically extracts shared patterns across actions (e.g., , ) - Handles union types (e.g., CalendarTime | CalendarTimeRange) - Validates generated grammar using the action-grammar compiler - Provides error feedback loop to fix syntax issues - Exports CLI tool: generate-grammar Files added: - packages/agentSdkWrapper/src/schemaToGrammarGenerator.ts: Main generator class - packages/agentSdkWrapper/src/generate-grammar-cli.ts: CLI interface Files modified: - packages/agentSdkWrapper/src/schemaReader.ts: Added union type handling - packages/agentSdkWrapper/src/index.ts: Export new generator classes - packages/agentSdkWrapper/package.json: Add action-grammar dependency and CLI command Co-Authored-By: Claude Sonnet 4.5 --- ts/packages/agentSdkWrapper/package.json | 4 +- .../src/generate-grammar-cli.ts | 169 ++++++ ts/packages/agentSdkWrapper/src/index.ts | 12 + .../agentSdkWrapper/src/schemaReader.ts | 19 + .../src/schemaToGrammarGenerator.ts | 563 ++++++++++++++++++ ts/pnpm-lock.yaml | 34 +- 6 files changed, 769 insertions(+), 32 deletions(-) create mode 100644 ts/packages/agentSdkWrapper/src/generate-grammar-cli.ts create mode 100644 ts/packages/agentSdkWrapper/src/schemaToGrammarGenerator.ts diff --git a/ts/packages/agentSdkWrapper/package.json b/ts/packages/agentSdkWrapper/package.json index 0591b37ae..f294bd8ce 100644 --- a/ts/packages/agentSdkWrapper/package.json +++ b/ts/packages/agentSdkWrapper/package.json @@ -17,7 +17,8 @@ }, "types": "./dist/index.d.ts", "bin": { - "agent-sdk-wrapper": "./dist/cli.js" + "agent-sdk-wrapper": "./dist/cli.js", + "generate-grammar": "./dist/generate-grammar-cli.js" }, "scripts": { "build": "npm run tsc", @@ -32,6 +33,7 @@ "@anthropic-ai/sdk": "^0.35.0", "@modelcontextprotocol/sdk": "^1.0.4", "@typeagent/action-schema": "workspace:*", + "action-grammar": "workspace:*", "agent-cache": "workspace:*", "aiclient": "workspace:*", "coder-wrapper": "workspace:*", diff --git a/ts/packages/agentSdkWrapper/src/generate-grammar-cli.ts b/ts/packages/agentSdkWrapper/src/generate-grammar-cli.ts new file mode 100644 index 000000000..839bf76a1 --- /dev/null +++ b/ts/packages/agentSdkWrapper/src/generate-grammar-cli.ts @@ -0,0 +1,169 @@ +#!/usr/bin/env node +// Copyright (c) Microsoft Corporation. +// Licensed under the MIT License. + +import { config } from "dotenv"; +import * as path from "path"; +import { fileURLToPath } from "url"; +import * as fs from "fs"; + +// Load .env file +const __filename = fileURLToPath(import.meta.url); +const __dirname = path.dirname(__filename); +const repoRoot = path.resolve(__dirname, "../../.."); +config({ path: path.join(repoRoot, ".env") }); + +import { SchemaToGrammarGenerator } from "./schemaToGrammarGenerator.js"; +import { loadSchemaInfo } from "./schemaReader.js"; + +interface GenerateGrammarOptions { + schema: string; + output?: string; + examplesPerAction?: number; + model?: string; + help?: boolean; +} + +function parseArgs(): GenerateGrammarOptions { + const args = process.argv.slice(2); + const options: GenerateGrammarOptions = { + schema: "", + examplesPerAction: 3, + model: "claude-sonnet-4-20250514", + }; + + for (let i = 0; i < args.length; i++) { + const arg = args[i]; + switch (arg) { + case "--schema": + case "-s": + options.schema = args[++i]; + break; + case "--output": + case "-o": + options.output = args[++i]; + break; + case "--examples": + case "-e": + options.examplesPerAction = parseInt(args[++i]); + break; + case "--model": + case "-m": + options.model = args[++i]; + break; + case "--help": + case "-h": + options.help = true; + break; + default: + if (!arg.startsWith("-") && !options.schema) { + options.schema = arg; + } + break; + } + } + + return options; +} + +function printHelp() { + console.log(` +Usage: generate-grammar [options] + +Generate an Action Grammar (.agr) file from an agent schema. + +Arguments: + schema-path Path to the .pas.json schema file + +Options: + -o, --output Output path for the .agr file (default: .agr) + -e, --examples Number of examples per action (default: 3) + -m, --model Claude model to use (default: claude-sonnet-4-20250514) + -h, --help Show this help message + +Examples: + # Generate grammar from player schema + generate-grammar packages/agents/player/dist/playerSchema.pas.json + + # Generate with custom output path + generate-grammar -o player.agr packages/agents/player/dist/playerSchema.pas.json + + # Generate with more examples per action + generate-grammar -e 5 packages/agents/player/dist/playerSchema.pas.json +`); +} + +async function main() { + const options = parseArgs(); + + if (options.help || !options.schema) { + printHelp(); + process.exit(options.help ?
