claude-pace

A lightweight Bash + jq statusline for Claude Code that displays rate limit pace delta (burn rate vs. time remaining), 5h/7d usage percentage, context window usage, git branch and diff stats. Compares current consumption rate against time remaining in each rate limit window to indicate whether quota is being used faster or slower than the window allows. Single file with no external dependencies beyond jq.

claude-code-agents

Comprehensive E2E development workflow with helpful Claude Code subagent prompts for solo devs. Run multiple auditors in parallel, automate fix cycles with micro-checkpoint protocols, and do browser-based QA. Includes strict protocols to prevent AI going rogue.

book-factory

A comprehensive pipeline of Skills that replicates traditional publishing infrastructure for nonfiction book creation using specialized Claude skills.

vellum-evals

Vellum evaluation SDK for running LLM test suites with custom metrics, dataset pinning, and CI workflow integration.

braintrust

Developer platform for logging, evaluating, and comparing LLM experiments with dataset versioning and scoring functions.

claudia-statusline

High-performance Rust-based statusline for Claude Code with persistent stats tracking, progress bars, and optional cloud sync. Features SQLite-first persistence, git integration, context progress bars, burn rate calculation, XDG-compliant with theme support (dark/light, NO_COLOR).

galileo-evaluate

Galileo evaluation and observability SDK for detecting hallucinations, data errors, and model weaknesses in LLM pipelines.

e2b

Open-source secure cloud sandboxes (Firecracker microVMs) for running AI-generated code. ~150ms cold start.

modal

Serverless cloud platform for running Python functions, containers, and AI workloads with zero infra management.

railway

Zero-config cloud platform for deploying agent backends, databases, and services from a Git push.

vercel

Frontend cloud platform with serverless functions and AI SDK integrations for deploying agent-facing UIs.

honeycomb

Honeycomb's OpenTelemetry-native observability platform: a high-cardinality event store ideal for tracing LLM pipelines and debugging slow agent traces.

baserun

Baserun captures LLM traces via a lightweight decorator-based SDK and provides a dashboard for debugging prompt chains, testing variants, and measuring quality.

claude-mountaineering-skills

Claude Code skill that automates mountain route research for North American peaks. Aggregates data from 10+ mountaineering sources like Mountaineers.org, PeakBagger.com and SummitPost.com to generate detailed route beta reports with weather, avalanche conditions, and trip reports.

humanloop-evals

Humanloop Python SDK with integrated evals, dataset versioning, and human + LLM judge scoring for production pipelines.

read-only-postgres

Read-only PostgreSQL query skill for Claude Code. Executes SELECT/SHOW/EXPLAIN/WITH queries across configured databases with strict validation, timeouts, and row limits. Supports multiple connections with descriptions for database selection.

agentbench

Use to put a number on harness quality: run an agent harness against a task set and get a score, so harness changes are validated by evidence. It is the eval backbone of a self-improving loop.
