2. Toast 1 β
Toast 1 is a backend-agnostic specialized retrieval agent that decomposes queries, gathers evidence, inspects sources, and curates context for standalone use or as a frontier-model subagent. Claims of frontier-level retrieval at materially lower cost and latency, backed by enterprise financial and legal benchmarks, generated 110 points and 30 comments at 37 points per hour. β π Traction signals: OfficeQA Pro V2: 70% answer correctness at approximately $1.15 per task. Harvey LAB: token usage fell from 80.6M to 23M across 33 tasks, with identical task score 55 and over 60% cost reduction. Standard runs cost approximately 0.016β0.023 per query with eight-second median latency; fusion costs approximately 0.05β0.07 with eleven-second median latency.

4. LuaCAD β
LuaCAD lets users script parametric 2D and 3D models in Lua, evaluate CSG in a Rust engine, render PNGs, and export seven mesh or SCAD formats. The combination of Lua scripting, native CSG, broad exports, live preview, and BOSL2 compatibility appealed to CAD and programming enthusiasts, producing 29 points at 17.4 points per hour.

5. Graft β
Graft builds linked Markdown and per-symbol code graphs that give coding agents persistent codebase context, integrating with Claude Code, Cursor, Codex, Gemini, and other agents. Concrete claims of fewer tokens, calls, and secondsβplus higher SWE-bench correctnessβdirectly address coding-agent cost and context loss, attracting 29 points and 4 comments at 17.4 points per hour. β π Traction signals: Controlled benchmark: 162 runs; tokens fell from 8,070 to 4,650 per task (-42%), tool calls from 4.2 to 2.3 (-46%), latency from 39.8s to 15.8s (-60%), with 93% correctness for both. SWE-bench Verified: 33/50 resolved versus 27/50; 23% fewer tokens and 32% less wall-clock time.

6. WhatCable β
WhatCable is a free, open-source macOS menu-bar app and CLI that explains USB-C cable speed, power, display paths, identity, negotiated behavior, and connection bottlenecks. A clear solution to opaque USB-C capabilities sparked unusually deep discussion: 72 points and 54 comments, despite a lower 14.5-point-per-hour velocity. β π Traction signals: 125 cable observations in the public database; available in 19 languages. WhatCable Pro unlocks 16 advanced features and works on up to 2 Macs.
