3. mksglu/context-mode: npm package that wires Copilot CLI and similar agents to context hooks (preToolUse, sessionStart, userPromptSubmitted). The README documents context-mode upgrade writing hook files and an ELv2 license.

4. jo-inc/camofox-browser: REST wrapper around Camoufox, a Firefox fork with C++ fingerprint spoofing, aimed at agents that get blocked on Playwright. Clone path starts a server at http://localhost:9377. First run downloads about 300MB.

6. affaan-m/ECC: Holdover elliptic-curve / agent-skills repo that led yesterday's board at rank 1. It is the only name that remains, now at 6 after the HTML-video and Markdown tools jumped it.

8. The-Swarm-Corporation/AutoHedge: Swarm-style finance agents for market analysis and trade workflows. No dated September 8 release note was isolated; the README positions it as an autonomous trading stack, which is why it sits beside other agent runtimes.

9. BraveOPotato/FckSignups: Single-file HTML directory of in-browser tools that require no accounts. GitHub listed 62 stars, MIT license, homepage fcksignups.com, created May 7, 2026.

10. bytedance/deer-flow: ByteDance SuperAgent runtime (Deep Exploration and Efficient Research Flow) on LangGraph. GitHub listed 80,960 stars, 11,142 forks, MIT. Docs describe DeerFlow 2.0 as a rewrite on a separate branch from 1.x. Avoid calling it a generic framework; the repo's own line is a batteries-included agent runtime.

What changed on GitHub since yesterday

Nine names are new. Only affaan-m/ECC remains, 1 to 6. Drop-offs: mattpocock/skills, cathrynlavery/diagram-design, NousResearch/hermes-agent, openai/skills, anomalyco/opencode, blader/humanizer, llvm/llvm-project, DietrichGebert/ponytail, ruvnet/ruflo.

The skills-pack wave (mattpocock, openai/skills) yielded to video renderers, document converters, and browser automation. That is a different agent-tool mix than Labor Day Monday.
