- What Is an Agent Harness? The Scaffolding Around LLMs, Explained
According to a DeveDigest report, the term "Agent Harness" has become a buzzword in AI development after DeepSeek released an open-source desktop client called DeepSeek Harness and OpenAI launched an Agents API at its developer conference. The article explains that the model supplies only reasoning, while the harness is the surrounding system — execution loop, tool calling, context and memory management, sandbox permissions and replayable logs — that lets an agent actually finish real work. It cites testing by data analytics company Databricks finding that the same model plugged into different coding-agent harnesses can differ by more than 2x in per-task cost with no change in task quality, partly because a harness's system prompts and tool declarations consume tokens.
DoNews · 🔥 6 - Caveman 4.0 trims coding agent tokens with terse output, compressed input
Caveman, an open-source skill and proxy for coding agents that topped GitHub Trending and Hacker News, released version 4.0: it makes agent replies terse (a sample 63-token answer becomes 20 tokens) and shrinks what agents read — logs, JSON, CSV, YAML and test output — for a claimed 33.2% cut in per-session input tokens. It adds Auto, which picks the model and effort per request, Blocks code mode that keeps agent-written scripts for reuse (one test run drops from 397 to 76 tokens), and prompt-cache warming while the user pauses. The project page says Adobe Research cited caveman-style output, JetBrains A/B tested it on 86 coding tasks with no measurable quality loss, and Elasticsearch Labs remade caveman mode for MCP; the Auto cost comparison — 54% cheaper than Claude Opus 5.5 at xhigh effort on 85 SWE-Interact/SWE-Together tasks — is self-reported, half-complete, and the score gap is stated to be within ±7 points.
GitHub Trending（每日） · 🔥 21 - Superpowers, an agentic skills framework for coding agents, trends on GitHub
Superpowers is an open-source (MIT) agentic skills framework and software development methodology from Jesse Vincent and the team at Prime Radiant. Once installed, it auto-triggers a set of composable skills: the agent draws out the user's real intent, produces a design document and a bite-sized implementation plan, then dispatches subagents to implement and review each task, emphasizing test-driven development, YAGNI and DRY. It must be installed separately per harness and supports Claude Code, Codex CLI, Cursor, Gemini CLI, GitHub Copilot CLI, OpenCode, Qwen Code, Kimi Code and others, with official plugin-marketplace listings for Claude Code and Codex.
GitHub Trending（每日） · 🔥 9 - ECC 2.2 hits GitHub Trending with an agent harness system for Claude Code, Codex
ECC is an MIT-licensed open-source project that describes itself as an "agent harness performance optimization system," giving coding agents such as Claude Code, Codex, OpenCode and Cursor a shared plan-test-implement-review-verify-remember workflow. Its repository claims 71 agents, 311 skills and 97 commands plus hooks, memory, continuous learning and AgentShield security scanning, installed via `npx [email protected] setup`, with a paid ECC Pro hosted GitHub App from $19 per seat per month for private repos. The project says it works best with Claude Code today, offers native plugin paths for Codex and Kimi Code, and ships capability-limited adapters for Cursor, Gemini, Zed, GitHub Copilot, Qwen and others.
GitHub Trending（每日） · 🔥 8 - OpenCode makes DeepSeek V4.1 Flash free, capped at 200K context
OpenCode announced that DeepSeek V4.1 Flash is now offered free on its platform, with the free tier observed to support a 200K context window, down from the model's 1M-context version. The move extends the earlier "Operation Cheepseek" program: OpenCode temporarily raised the model's allowance in its OpenCode Go plan from $15 to $60 in September, then to $80 on October 12, and calls under the free offer no longer count against that allowance. DeepSeek V4.1 Flash launched on September 10, 2026 as a native multimodal MoE model with a 552B-parameter main trunk plus 196B Engram conditional-memory parameters, a causal encoder-decoder design in which the first 20 of 40 language layers are encoders and the last 20 decoders, cutting prefill compute roughly in half; DeepSeek's own platform lists no free API tier. Community reports flag volatile throughput: one user saw up to about 490 tokens/s on the ollama cloud platform, but speeds can fall to 50-60 tokens/s around midday to afternoon and decline as context grows, reaching roughly 50 tokens/s at 200K.
IT之家 AI · 🔥 8 - Multi-harness agent plugin marketplace wshobson/agents trends on GitHub
wshobson/agents, a multi-harness agentic plugin marketplace, appeared on GitHub Trending as a way to use one collection of plugins, agents, skills and commands across Claude Code, OpenAI Codex CLI, Cursor, OpenCode, Antigravity CLI, GitHub Copilot and Pi. The catalog lists 94 plugins (92 local, 2 external), 202 agents, 184 skills and 105 commands, with one Markdown source in the Claude Code plugin format and adapters generating each harness's format. It is MIT licensed and ships static skill checks via plugin-eval, though the LLM-judge and Monte Carlo layers are labeled experimental and not validated against human labels.
GitHub Trending · Python · 🔥 3 - Inside Uber's AI infrastructure: Model Gateway, AIFX and agentic developer tooling
In a Pragmatic Engineer podcast episode, Uber distinguished engineer Uday Kiran Medisetty describes the company's internal AI developer infrastructure. Uber built a Model Gateway in 2023 so AI applications stay model- and harness-agnostic, switching between Anthropic, OpenAI and other vendor models as well as open models Uber runs itself, with a security middleware called AI Guard, per-user spend tracking and audit logs layered on top. AIFX wraps Claude Code, Codex and OpenCode so settings, skills and plugins follow engineers when they change harnesses. AI spend uses allocated tiers with manager sign-off plus a CostCheck plugin for savings tips, and the source says token costs fell about 50% in recent months. Code review remains a bottleneck: Uber's Code Review tool runs AI review, attaches screenshots or videos and assigns risk scores before a human looks. After CI jobs more than doubled in 12 months, Uber declared an internal "code red" and moved simple jobs such as linting and builds into the inner loop, run by agents before a PR is opened.
The Pragmatic Engineer · 🔥 0 - Vercel Labs open-sources agent skills CLI
Vercel Labs has published an open-source command-line tool, skills, for managing the "agent skills" ecosystem, which it says supports OpenCode, Claude Code, Codex, Cursor and 75-plus other coding agents. Users can install SKILL.md skill packages with npx skills add from GitHub shorthand, full GitHub, GitLab or Azure Repos URLs, any git URL, direct download links or local paths, and can use npx skills use to generate a prompt for a single skill without installing it or to launch a supported agent with that prompt. The CLI also offers list, find, update, remove and init subcommands, project-level or global installation, symlink or copy methods, and reuses existing Git, GitHub CLI or SSH authentication for private repositories.
GitHub Trending（每日） · 🔥 0 - Tencent's OrcaTerm adds Tmux session persistence, free AI tokens
Chinese developer site OSChina reports that Tencent's OrcaTerm terminal tool has been updated again, this time adding Tmux session persistence; it notes that OrcaTerm's existing AI features come with free token use, aimed at people who write code and troubleshoot daily. The suggested workflow is to start tmux in OrcaTerm's local terminal and split it into two panes, with OpenCode writing features on the left and Claude Code writing tests on the right, each agent working in its own directory so they don't edit the same file at once. The post adds that you can simply close the terminal while both agents are still working and reopen it later (the source text is truncated at that point).
开源中国 · 🔥 0 - OpenCode 2.0 ships with a persistent background service
The open-source AI coding agent OpenCode 2.0 has been officially released, with its maintainers calling it a "major overhaul" that draws on the experience of millions of daily active users and aims to deliver a system that "scales to everything an agent needs." Among the many new features, the most consequential is that its background service is now actually used: OpenCode has adopted a client/server model from the start, but it was not enabled by default and only heavy users relied on it. According to OSChina, the release also lets models write scripts to orchestrate tools.
Product Hunt · 🔥 3 - NVIDIA Dynamo adds session-aware routing and KV cache for agentic inference
A PyTorch blog post details how NVIDIA Dynamo turns request-level serving into program-aware serving using one session-level identifier, with child sessions carrying a parent_session_id. Dynamo recognizes the session headers that Claude Code, Codex and OpenCode already emit, while other harnesses opt in via X-Dynamo-Session-ID, and plugins exist for Hermes and OpenClaw. The post also covers session-aware routing and admission control (porting a scheduler from the ThunderAgent paper), a shared KV cache indexer, the Session-Prefix Indexer and proposed KvHint interface, plus DYN_REQUEST_TRACE=1 trace capture with AISimulate offline replay and AIPerf live benchmarking.
PyTorch Blog · 🔥 0 - Step 5 Preview free for a week across several coding tools
StepFun says its flagship model for agentic and professional work, Step 5 Preview, is free for one week in OpenCode, Nous Portal (with Hermes Agent), Cline and Kilo. Partners describe it as a 600B-parameter MoE with 27B active per token, a 1M-token context and vision, with OpenCode noting zero data retention. Cline claims it scores ahead of Kimi K3 and GLM-5.3 on DeepSWE, while Nous says its 33.89 Hermes Index score matches GPT-6 Luna — both are partner claims.
阶跃星辰 StepFun · 🔥 0 - Uber open-sources ADR agentic AI detection and response system
Uber has open-sourced ADR (Agentic AI Detection and Response), an enterprise security system for AI agents that is deployed in production at the company. The repository includes ADR Discovery, ADR Sensor, ADR-Bench and ADR Detector, which inventory AI apps, CLI agents, IDE extensions, local model runtimes and MCP servers on endpoints, and capture agent intent, tool use and execution traces from 7+ coding tools including Claude Code, Cursor, Codex, GitHub Copilot CLI, DeepSeek Harness, opencode, Claude Desktop and Gemini CLI. The project says ADR-Bench spans 304 tasks and 134 MCP servers across all 17 agent attack techniques; the ADR Prevention component and the ADR Explorer engine are not part of the open-source release, and an accompanying paper was accepted to MLSys 2026.
GitHub Trending · Python · 🔥 0 - cmux: open-source macOS terminal with notifications for AI coding agents
manaflow-ai's cmux is an open-source, GPL-licensed macOS terminal that renders via Ghostty's libghostty and is built natively in Swift/AppKit rather than Electron. Its sidebar provides vertical tabs showing git branch, linked PR status and number, working directory, listening ports and latest notification text, and it hooks into agents such as Claude Code and OpenCode through OSC 9/99/777 sequences and a cmux notify CLI, giving a waiting agent a blue pane ring and a lit-up tab. It also adds a scriptable in-app browser ported from agent-browser, workspaces with horizontal and vertical splits, a CLI and socket API for automation, and resume integrations for Claude Code, Codex, Gemini, Cursor CLI and others; it installs via DMG or Homebrew, with separate nightly builds.
GitHub Trending（每日） · 🔥 0 - Addy Osmani open-sources agent-skills, a 25-skill pack for AI coding agents
Developer Addy Osmani has published agent-skills on GitHub, an open-source pack that encodes senior-engineering workflows, quality gates and best practices as 25 skills (24 lifecycle skills plus a meta-skill) mapped to six phases: DEFINE, PLAN, BUILD, VERIFY, REVIEW and SHIP, with nine slash commands such as /spec, /plan, /build, /test, /review and /ship. The repo says the pack installs via the npx skills CLI into 70+ agents including Claude Code, Cursor, Codex and GitHub Copilot, with native plugin and local install paths; its README also notes that installing a single skill skips the repo-level references/ checklists, a portability gap tracked in issue #361.
GitHub Trending（每日） · 🔥 0 - AI's simmering question: where is all the automation?
A The Information column frames the industry debate over why automation has not arrived even as OpenAI said its unreleased model solved or made major progress on hundreds of significant math and computer science problems. Cognition founder Scott Wu argued that ever-more-capable agents plus more data centers, memory and sandboxes will yield "virtual employees," while ex-OpenAI researcher Diogo Almeida, now at TypeSafe AI, maker of Jev, said today's LLMs are optimized for assistance and fail at unattended automation. Anthropic's Claude Code product lead Cat Wu conceded much automation stalls at a semi-automated stage where Claude does 80% and a human does 20%.
The Information · 🔥 0 - Omnigent open-source meta-harness orchestrates Claude Code, Codex and other agents
Omnigent is an open-source AI agent framework and "meta-harness" that, per its project documentation, mixes Claude Code, Codex, Cursor, OpenCode, Hermes, Pi and user-defined YAML agents in the same session, with sessions that follow you between terminal, browser, phone and a macOS desktop app. The README also claims support for first-party API keys or Claude/ChatGPT subscriptions, cloud sandboxes such as Modal, Daytona, E2B and Kubernetes, and policies that pause for approval, cap spend or limit tool access, plus session sharing for teammates. The repository is currently listed on GitHub Trending for Python.
GitHub Trending · Python · 🔥 0 - Agency Agents ships a native desktop app for its agent roster
Agency Agents is a growing collection of AI agent personas that started from a Reddit thread and months of iteration, spanning engineering categories such as frontend, backend, DevOps, security and data, with each agent given its own identity, workflows and deliverables. The project now offers a native macOS, Linux and Windows app that browses the full roster and installs agents into Claude Code, Cursor, Codex, Gemini CLI, OpenCode, Qwen and Osaurus in one click, alongside script-based installs and auto-updates. The repo describes the agents as "production-ready," a claim that comes from the project itself rather than independent testing.
GitHub Trending（每日） · 🔥 0 - Diagram Design 2.5.10 adds ten more diagram layout grammars
Diagram Design is a diagramming skill/plugin for agent hosts including Claude Code, Codex, GitHub Copilot, Factory Droid and Pi. It emits self-contained HTML + SVG with no build step, JavaScript or external image dependencies, and each visual type ships in minimal-light, minimal-dark and full-editorial variants. Creator Cathryn Lavery (LittleMight) added ten layout grammars in v2.5.10: Sankey, fishbone, Wardley map, kanban, user journey, deployment, dependency graph, UML class, story map and database schema. The skill can also read a website to match brand colors and redraw draw.io, Mermaid or Excalidraw sources at a chosen format, size and detail level; official builds come only from the repository.
GitHub Trending（每日） · 🔥 0 - claude-mem: cross-session persistent memory plugin for coding agents
claude-mem is an open-source persistent memory plugin that captures an agent's tool-use observations during sessions, compresses them into semantic summaries with AI, and injects relevant context into later sessions; it advertises support for Claude Code, OpenClaw, Codex, Gemini, Copilot, OpenCode and more. It installs with a single npx command, stores data in a local SQLite database with Chroma-based hybrid semantic and keyword search, and lets users bring their own OpenRouter or Gemini key, fall back to an Anthropic plan, or subscribe to its hosted memory service (the project claims a 30-day free trial). The repository appeared on GitHub Trending; the usage-gain and trial claims come from the project's own README and are not independently verified.
