Betterglob

Better OpenCode Tools is a monorepo of standalone OpenCode plugins that replace the built-in glob, grep, and read tools with faster, stricter, and more predictable implementations.

The goal is simple: keep the familiar OpenCode tool IDs while improving the runtime behavior behind them.

✨ What is included?

Plugin	Replaces	Main advantage
opencode-betterglob	glob	Fast ripgrep-powered file discovery with safer limits and native-style output.
opencode-bettergrep	grep	Advanced local search with ripgrep, fallback handling, rich filters, and hard-kill timeouts.
opencode-betterread	read	Real plugin replacement for file/directory/notebook reading with stricter permissions and robust output budgeting.

🆕 Release 0.2.2

• betterread: @ is now allowed in scoped paths, with safer permission glob handling.
• bettergrep: added explicit paths: string[] support and stricter mixed-target normalization.
• All packages are aligned to OpenCode 1.17.3 and effect 4.0.0-beta.74.

🚀 Why use these instead of the native tools?

⚡ Faster file operations

glob and grep use ripgrep where possible, giving excellent performance on large repositories while still returning model-friendly output.

🧯 Safer execution behavior

The plugins include hardened timeout and process handling, bounded output budgets, safer path handling, and explicit behavior around partial results.

🧭 Better agent ergonomics

Outputs are formatted for AI agents: line numbers, continuation hints, structured metadata, and clear notes when results are partial, capped, or metadata-only.

🧩 Drop-in OpenCode integration

Each package registers using the same tool ID as the built-in tool it replaces: glob, grep, or read. No OpenCode core patching is required.

📦 Packages at a glance

🔍 opencode-betterglob

• Uses rg --files for fast file discovery.
• Supports sorting, hidden files, symlink behavior, limits, and timeouts.
• Keeps native-compatible plain path output.
• Avoids returning enormous default result sets by using safer defaults.

⚡ opencode-bettergrep

• Uses ripgrep as the primary search backend.
• Supports content search, count mode, files-with-matches, context, multiline, PCRE2, file globs, sorting, and result limits.
• Includes robust timeout handling with SIGTERM to SIGKILL escalation.
• Provides fallback behavior for environments where ripgrep is unavailable.

📖 opencode-betterread

• Fully replaces the agent-facing read tool as a real plugin tool.
• Handles text files, directories, notebooks, PDFs, images, binary files, and missing-file suggestions.
• Preserves numbered-line output and continuation hints.
• Implements plugin-side read and external-directory permission checks.
• Returns metadata/text for images and PDFs because the current OpenCode plugin API does not expose built-in-style file attachments.

📦 Recommended installation (npm)

For normal installs, use npm and add only the packages you want:

npm install opencode-betterglob
npm install opencode-bettergrep
npm install opencode-betterread

Then register the installed packages in your OpenCode config by package name:

{
  "plugin": [
    "opencode-betterglob",
    "opencode-bettergrep",
    "opencode-betterread"
  ]
}

Use only the packages you actually want to enable.

🛠️ Manual installation from source (alternative)

Use the source/file flow if you want to run the plugins directly from a local checkout or test local unpublished changes.

Clone and build the monorepo:

git clone https://github.com/dhaern/better-opencode-tools.git
cd better-opencode-tools
bun install
bun run build

Then add the packages you want to your OpenCode config:

{
  "plugin": [
    "file:///path/to/better-opencode-tools/packages/opencode-betterglob",
    "file:///path/to/better-opencode-tools/packages/opencode-bettergrep",
    "file:///path/to/better-opencode-tools/packages/opencode-betterread"
  ]
}

Use only the packages you actually want to enable.

🧪 Development

bun install
bun run typecheck
bun test
bun run build
bun run check

The root scripts run across all packages under packages/*.

📝 Issue reporting

This repository uses GitHub issue forms for bug reports, feature requests, and questions. A lightweight issue triage workflow adds plugin labels and asks only for the minimum missing details when a report is incomplete.

⚠️ Known limitations

• opencode-betterread cannot return built-in-style image/PDF attachments because the current public plugin API only supports text output and metadata.
• The plugins are intended to replace the agent-facing tool calls. They do not patch private OpenCode internals.
• If multiple plugins replace the same tool ID, OpenCode plugin load order determines which one wins.

🤝 Contributing

Contributions are welcome. Keep changes local to the plugins unless a core change is explicitly proposed and reviewed separately.

🙏 Special thanks

Special thanks to oh-my-opencode-slim for pushing the OpenCode plugin ecosystem forward and for helping inspire parts of the standalone plugin direction taken here.

If you want a broader day-to-day OpenCode plugin setup beyond the standalone tool replacements in this repository, it is also worth checking out and trying.

Before opening a PR, run:
