Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@herdctl/chat

Shared chat infrastructure for herdctl connectors

npm version License: MIT

Documentation: herdctl.dev

Overview

@herdctl/chat is the shared foundation that powers chat integrations in herdctl. It provides session management, streaming message delivery, error handling, and message splitting used by @herdctl/discord, @herdctl/slack, and @herdctl/web.

Herdctl is an open-source system for running fleets of autonomous AI agents powered by Claude Code. This package is part of the herdctl monorepo.

Note: This is an internal infrastructure package. Most users should use the platform-specific connectors (@herdctl/discord, @herdctl/slack) or the web dashboard (@herdctl/web) rather than this package directly.

Installation

npm install @herdctl/chat

What It Provides

Session Management

ChatSessionManager tracks conversation sessions per channel or DM. Sessions are persisted to disk and automatically expire after a configurable timeout (default: 24 hours). When a user sends a message, the session manager either resumes the existing session or creates a new one, preserving conversation context via Claude SDK session resumption.

Streaming Responses

StreamingResponder delivers agent responses incrementally as they are generated, rather than waiting for the full response. It buffers content and sends complete chunks at configurable intervals, respecting platform rate limits.

Message Splitting

Long agent responses are automatically split at natural breakpoints (paragraph breaks, sentences, clauses) to fit within platform character limits (Discord: 2,000, Slack: 4,000). This ensures messages remain readable without cutting mid-sentence.

Error Handling

A shared error handler classifies errors (transient, rate limit, authentication, etc.), provides user-friendly messages, and implements retry logic with exponential backoff. Platform connectors use this to handle failures gracefully without crashing.

DM Filtering

The DM filter enforces access control for direct messages: enabled/disabled toggle, allowlist, blocklist, and chat mode (auto vs. mention). Blocklist takes precedence over allowlist.

Message Extraction

Utilities for extracting text content from Claude SDK message formats, handling direct strings, nested message objects, and content block arrays.

    +-- @herdctl/slack   (Slack-specific integration)
    +-- @herdctl/web     (Web dashboard chat)

Each platform connector implements the IChatConnector interface and uses the shared infrastructure for everything that isn't platform-specific.
