GitHub's guide explains agent skills as versioned directories centered on a SKILL.md file that capture repeatable task instructions shareable across agents, while the environment still supplies tools, credentials, and permissions. Using examples like Proof Agent for adversarial verification and Data Forge for a multi-skill data pipeline, it recommends keeping project configuration in a manifest, sharing execution paths between skills, and placing human checkpoints and CI checks in workflows. It also covers packaging skills for clients such as Claude Code, Cursor, and GitHub Copilot, and notes that applications suit workflows needing stable interfaces, shared state, audit trails, or permissions enforced outside the model.

GitHub reports over 1.2 billion commits in one week this October, more than 400% above a year earlier, while a Faros AI study found pull requests spent 441% longer in review as teams moved from low to high AI adoption. The post outlines an agentic engineering workflow across Plan, Build, Verify, and Observe, describing Copilot features such as Plan Mode, cloud sandboxes, session continuity, stacked pull requests, Copilot code review, Agentic Autofix, and Agent Merge. It advises starting with one frustrating piece of work and putting an agent on it before expanding across the process.

GitHub has released Copilot Fusion in GitHub Copilot, a runtime orchestration system that selects and coordinates models from Anthropic and OpenAI, including Claude Opus 5.5, Claude Sonnet 5.5, GPT-6 Astra and GPT-6 Sol, to optimize performance, cost and latency per task. In Artificial Analysis' Coding Agent Index v2.0, its max setting in GitHub Copilot CLI scored 2 points below Opus 5.5 in Claude Code at half the cost per task ($5.59 versus $11.42), leading Terminal-Bench 4.0 at 71 while ranking third on FrontierCode at 51 and scoring 57 on SWE-Atlas-QnA-AA. It used 7.2M tokens per task, roughly half of Claude Opus 5.5 in Claude Code and 30% less than Devin Fusion with Opus 5.5 (max) + GPT-6 Luna (high).
Why it matters: Offers concrete benchmark and cost comparisons for a multi-model orchestration approach, useful for readers weighing coding-agent performance against token spend.
Replit launched Cloud Agents for existing repositories, letting anyone on a team describe a change in plain language and have an agent find the code, test it in cloud sandboxes, and open a tested pull request in GitHub or GitLab with screenshots and video. The feature includes shared environments set up once by an admin, review feedback that agents turn into proposed team skills for engineer approval, and a Slack integration for starting changes from threads; it is available to all Pro and Enterprise customers.
Why it matters: Announces a notable shift in how non-engineers can contribute tested code changes to production repositories, with concrete details on testing, review, and setup.

GitHub interviews three Java Champions—Vlad Mihalcea, Patrick Baumgartner, and Frank Delporte—about using GitHub Copilot in production and open source work, including a Hypersistence Optimizer app built in two days, a 900-slide Reveal.js to Marp migration, and diagnosing a Pi4J bug where virtual threads pinned in native poll() calls left a fifth button unresponsive. They emphasize reviewing generated code, defining verification gates, and keeping humans accountable for what ships.
This GitHub tutorial explains how to open a GitHub Copilot app session in VS Code so its conversation, diff, and worktree carry over, letting you review changes line by line, edit by hand, run tests locally, and push updates to the session's pull request. It lists prerequisites and walks through each step, including prompting Copilot further from the sidebar and committing with normal Git commands.
GitHub describes a two-stage secret scanning pipeline that uses regex candidate generation followed by a fine-tuned ModernBERT classifier that reads each candidate alongside its file path, variable names, and surrounding code. Compared with its previous LLM-based pipeline, GitHub reports 11.5% higher repository owner-weighted acceptance, 86% lower median post-push scan execution time, and more than 98% lower serving cost, with offline evaluation showing 13% higher precision and 19% higher recall. The efficiency gains made it practical to extend generic secret detection to push protection.
GitHub's beginner guide explains four ways to give Copilot project context: repository custom instructions in .github/copilot-instructions.md plus path-specific files in .github/instructions, agent skills in .github/skills for repeatable procedures, custom agents in .github/agents for broader specialized tasks, and MCP servers that connect Copilot to external tools and data sources such as Playwright. It suggests starting small by adding one convention you keep explaining to .github/copilot-instructions.md, and points to Awesome Copilot for community-shared examples.
GitHub reports that one in three pull requests now involves an AI agent, up from fewer than one in 10 a year ago, while a new secret appears in public code roughly every two seconds. GitHub introduces a ModernBERT-based classifier built with Microsoft Applied Sciences that extends push protection to unstructured secrets, evaluating candidate batches in under two milliseconds and potentially more than doubling the secrets it can prevent. The feature enters private preview and will be available to organizations with GitHub Secret Protection on Enterprise Cloud and GitHub Teams, and will ship with GitHub Enterprise Server 3.23 in public preview.
GitHub introduces ReviewBench, an open benchmark for AI code review built from analysis of 103.9 million GitHub pull requests, containing 219 public pull requests across 19 languages with a multi-source golden set labeled for severity and category. It reports grounded and augmented precision, recall, and F1 metrics, uses Claude Sonnet 5 as the LLM grader under a published rubric, and had its ground-truth findings independently re-labeled by senior engineers with 96.6% agreement. GitHub says ReviewBench's offline predictions for a Copilot code review multi-model ensemble matched a later A/B test, which showed an 8.0% rise in addressed rate, 13.6% in recall, 61% in comment volume, and an 8.0% drop in cost per review.
Why it matters: It offers a concrete, reproducible methodology and public dataset for comparing AI code reviewers, plus evidence on how offline scores tracked a production experiment.
GitHub outlines three skills developers should strengthen as AI reshapes their work: learning to direct AI agents rather than just use them, not trusting AI's first answer and instead having a second model critique it before review, and using time saved on implementation to tackle broader problems like customer needs and architectural tradeoffs. The post illustrates these with examples such as coordinating multiple agents on an authentication flow and a second model critiquing a SQL query. It notes GitHub Copilot's built-in Rubber Duck agent uses a second model to critique plans, code, and tests.
GitHub explains canvases in the GitHub Copilot app: customizable, bidirectional interfaces such as kanban boards, checklists, or dashboards that you create by entering the /create-canvas skill in an agent session and describing the workflow in plain English. The agent builds the interface in the right-side panel, and both you and the agent can update its shared state immediately without a separate sync step. Canvases are saved as extensions for reuse or team sharing, and ready-made ones are available through Awesome Copilot.
