packages/ — Monorepo Packages

Generated: 2026-05-20

OVERVIEW

23 sibling packages across 4 roles. None of these are published as part of the main oh-my-opencode / oh-my-openagent npm dist (root package.json files only ships dist/, bin/, postinstall.mjs). They are sibling packages with their own publication / deployment targets.

ROLE MAP

Role	Count	Packages
Platform binaries	11	One per (OS × arch × variant). Uniform layout: bin/ + package.json only. Selected at install time by bin/ shim + postinstall.mjs.
MCP packages	2	lsp-tools-mcp (git submodule), ast-grep-mcp
Core packages	9	utils, model-core, prompts-core, rules-engine (was rules-core), agents-md-core, ast-grep-core, comment-checker-core, hashline-core, boulder-state
Web	1	web

PLATFORM BINARIES (11)

oh-my-opencode-darwin-arm64, oh-my-opencode-darwin-x64, oh-my-opencode-darwin-x64-baseline, oh-my-opencode-linux-arm64, oh-my-opencode-linux-arm64-musl, oh-my-opencode-linux-x64, oh-my-opencode-linux-x64-baseline, oh-my-opencode-linux-x64-musl, oh-my-opencode-linux-x64-musl-baseline, oh-my-opencode-windows-x64, oh-my-opencode-windows-x64-baseline.

Each contains only a bin/<binary> and a package.json. Built by script/build-binaries.ts via bun compile. Published by the publish-platform.yml workflow.

-baseline variants are pure x86_64 (no AVX2) for older CPUs. -musl variants link against musl libc for Alpine. Runtime selection happens in bin/ and postinstall.mjs.

MCP PACKAGES

Package	Layout	Purpose
lsp-tools-mcp/	Full standalone project (own .git submodule, .github/, CHANGELOG.md, LICENSE, src/, test/, biome.json, vitest.config.ts)	Serves lsp_diagnostics, lsp_goto_definition, lsp_find_references, lsp_symbols, lsp_prepare_rename, lsp_rename, lsp_status tools via stdio MCP. Registered as tier-1 MCP lsp in src/mcp/.
ast-grep-mcp/	Internal package (src/, dist/, tsconfig.json)	Serves ast_grep_search + ast_grep_replace tools via stdio MCP. Registered as tier-1 MCP ast_grep.

CORE PACKAGES

Package	Layout	Purpose
utils/	src/, tsconfig.json	Shared utilities: deep-merge, snake-case, frontmatter, file-utils, etc.
model-core/	src/, tsconfig.json	Model resolution pipeline with ProviderCache dependency injection.
prompts-core/	src/, prompts/, test/, tsconfig.json	Harness-neutral markdown prompt loading, model-variant routing, and bundled mode prompts for search/analyze/team/hyperplan.
rules-engine/	src/, tsconfig.json	Rule discovery + matching engine (renamed from rules-core).
agents-md-core/	src/, tsconfig.json	AGENTS.md walk-up discovery and injection logic.
ast-grep-core/	src/, tsconfig.json	ast-grep types, pattern-hints, and runner core with injectable spawn.
comment-checker-core/	src/, tsconfig.json	apply-patch parser and binary runner with injectable spawn.
hashline-core/	src/, tsconfig.json	Hashline edit primitives and diff helpers shared by adapter shims.
boulder-state/	src/, tsconfig.json	Work tracking state machine with split storage.

WEB

Package	Sub-AGENTS.md	Purpose
web/	yes (packages/web/AGENTS.md)	Marketing site. Next.js 15 + Cloudflare Workers via @opennextjs/cloudflare. Independent bun.lock + tsconfig.json. Only place in the repo where @/* path aliases are allowed.

CONVENTIONS

• No new package without explicit need. Adding a sibling package complicates publish + CI. Justify the boundary first.
• Platform binaries are generated. Do NOT edit by hand. Modify script/build-binaries.ts.
• lsp-tools-mcp is a git submodule. Initialize with git submodule update --init --recursive after fresh clone.
• packages/web/ is excluded from root bun test via bunfig.toml. It has its own web-ci.yml workflow.
• CI builds for non-platform packages run as part of the root ci.yml. Platform binaries build only via publish-platform.yml when triggered by publish.yml.

ANTI-PATTERNS

• Never publish a sibling package manually. Use the GitHub Actions workflows.
• Never copy code between packages by hand. Either share via a core package or accept the duplication and document it.
• Never modify bin/<binary> inside a platform package — those are compiled artifacts.
