TokenScale is a browser-based AI API pricing explorer that compares 16 providers, converts token costs into familiar real-world examples, and shows how batch, cache, and conversation length affect spend.

An open-source ID library that generates human-readable, token-efficient IDs for AI agents and LLM workflows, with parsing, validation, deterministic IDs, and alias mapping utilities.

GitHub Blog article on reducing token usage and API cost in agentic coding workflows, including logging token usage, removing unused MCP tools, replacing GitHub MCP with GitHub CLI, and measuring efficiency gains.

Tokenyst is a local-first CLI for tracking Claude Code token usage and API costs against task budgets. It captures session spend, shows progress in the terminal, and stores data on your machine.

An open-source browser experiment that uses a visual LLM to read HTML and hallucinate the rendered page instead of using a traditional rendering engine.

Pu.sh is a lightweight coding-agent harness delivered as a shell script. The page shows a direct install-and-run flow, a no-dependency setup, and links to GitHub, docs, and an MIT license.

A Go-based terminal markdown note editor with a centered Focus Line, rendered markdown around the active line, and file-based notes stored as plain .md files.

A GitHub repository for Claude Code skills, subagents, and hooks designed to make agent work more verifiable, including regression-proof fixes, handoff notes, and installable plugin workflows.

A PHP framework built around the Action-Domain-Responder pattern, with a small core and an emphasis on code that humans and agents can both follow.

A self-hosted CI system with an embedded runner that can generate pipelines through an LLM, with examples for Python, Go, Node.js, Ansible, Chef, and agent deployment workflows.

A cross-platform CLI release for switching between isolated Claude Code accounts on Linux and macOS without re-login, with per-profile storage and Keychain-backed credentials on macOS.

Browser-based infrastructure for running coding agents persistently, with workspace management, status tracking, and support for tools like Claude Code and Codex.

A French public demo of an autonomous Claude agent competing in timed money-making challenges, with live episode tracking, Stripe payments, and public results from prior runs.

Pulse is an AI incident response tool that watches systems, diagnoses PagerDuty incidents with Claude, and posts suggested fixes to Slack for one-click resolve or escalation.

CodeZero is a no-code backend and automation platform that now includes AI flow generation, a module system, and an execution results view inside the IDE.

Humbug is an open-source, GUI-based agentic development platform for human-AI collaboration. The page says it supports multi-model workflows, local and cloud LLMs, tool use, approvals for risky actions, and local-first data handling.

Hawkeye is a developer tool for fast local code search and navigation across large codebases, with editing, focused replace, tabs, shortcuts, and Perforce support.

A live demo that shows an AI agent using KINETK’s API/MCP workflow to analyze live social signals and generate an evidence-backed launch and growth plan for a product prompt.

A custom Claude Code status line script that shows workspace, model, session, context usage, token totals, code churn, and 5-hour/7-day rate-limit runway in two colored rows.

A macOS utility that keeps a MacBook awake while AI agents are running, then lets normal sleep resume when they go idle. It includes install scripts, hooks for Claude Code and Codex, and a menu bar status indicator.

A TypeScript zot extension that adds an /answer slash command for responding to numbered questions from the latest assistant message in an interactive panel.

A research preprint describing ADHD, a parallel divergent ideation method for LLM coding agents that isolates branches, uses cognitive frames, and then prunes with a separate critic pass.

A Claude Code plugin that plays background lounge or elevator music while the agent is thinking, with track rotation, stop/start controls, and status-line integration.
