|---|---|---|---|
| What it is | Full system prompts, tool definitions and model configs extracted from 30+ commercial AI coding products — Claude Code, Cursor, Devin, Copilot, v0, Windsurf, Replit, Manus. ~141k stars. | Anthropic's first-party guide, built around one stated premise: the context window is the most important resource to manage, and performance degrades as it fills. Covers /clear, /compact, /rewind, /btw, a CLAUDE.md keep-or-cut table, subagents for investigation, and the explore→plan→code→commit workflow. | Renders live session telemetry in the Claude Code status line: context-window fill, real token counts (not estimates), cost, active tools/skills/MCP servers, running subagents, todo progress and subscription rate-limit headroom. ~26k stars. |
| Category | Cost & efficiency | Cost & efficiency | Cost & efficiency |

| Why builders pick it | A study reference for how production teams write terse tool descriptions and budget context at scale. Directly useful if you are writing your own skills or agent prompts for the content pipeline. | Read this before installing any of the compression tools. Most of the savings people chase with plugins come free from context discipline — and it names the failure patterns (kitchen-sink session, infinite exploration, over-specified CLAUDE.md) so you can recognize your own. | Install this first. It is the measurement layer — you cannot control spend you cannot see, and context fill is the variable that quietly degrades output quality on long sessions. |
| Watch out for | Ambiguous link. A second credible candidate exists (asgeirtj/system_prompts_leaks, ~63k stars). Both are prompt corpora; open the original link to confirm which was meant. | not logged | Requires Claude Code 1.0.80+ and Node 18+. Forks exist — pin the jarrodwatts original. |
| How to wire it up | not logged | not logged | /plugin marketplace add jarrodwatts/claude-hud |
