Claude Code includes slash commands for session and context management, including /resume to continue prior sessions, /branch to fork conversations, /diff to review changes, /compact to compress context, and /security-review to audit code before deployment.
Anthropic's Claude Code is a command-line interface for AI-assisted software development that reads and writes files, executes commands, manages Git workflows, and reasons across up to 1 million tokens of codebase context. It runs on Claude Sonnet 4.6 by default for Pro users and Opus 4.6 on Max ...
AI coding agents like Claude Code, GitHub Copilot, and Cursor are autonomously installing packages without clear security ownership, creating exploitable gaps in enterprise software supply chains. Snyk researchers scanning nearly 4,000 AI agent skills found more than a third contained at least on...
A developer released AgentKit, a CLI tool published as @patricksardinha/agentkit-cli on npm, that generates markdown orchestration files to structure multi-agent workflows for Anthropic's Claude Code. The tool requires no API key and works by reading a plain-language project blueprint to produce ...
OpenCode, an open-source AI coding tool co-founded by Dax Raad, grew from approximately 650,000 to nearly 8 million monthly active users within a few months, alongside nearly 1 million daily active users. After Anthropic blocked integration with Claude Code, OpenCode pursued partnerships with Ope...
OpenAI, Thrive, and Crete built a tax agent using Codex that automates tax filings and incorporates self-improvement mechanisms to increase accuracy and speed up workflows.
Warp integrated GPT-5.5 and other OpenAI models into its development platform to coordinate coding agents across local, cloud, and open-source workflows.
Uber's CTO said the company's budget for Anthropic's Claude Code was already exceeded, prompting the COO to warn that AI token costs must be tied to measurable output. Startups including Lanai have released tools such as Token Tuner to help enterprises identify where cheaper models can reduce unn...
Scaling AI agents across organizations faces three obstacles: security reviews that can take over nine months, MCP tool overload that consumes up to 150,000 context-window tokens per Anthropic's estimates, and agents lacking basic organizational knowledge. The article proposes a "Context Lake" as...
A developer guide on Dev.to outlines prompting techniques for Anthropic's Claude, recommending users specify framework, language, expected behavior, and output format in requests. It also covers chain-of-thought prompting and Claude's extended thinking feature, available on Sonnet 4.6 and Opus 4....
Anthropic's Claude Code processes code as text through tokenization and pattern matching, without executing it. Current models include Claude Sonnet 4.6 and Opus 4.6/4.7 with 1M-token context windows, and Claude Haiku 4.5 with 200K tokens; the Claude 3 Haiku model has been retired.
Researcher Udit Akhouri released a tool called ADHD, built on Anthropic's Claude Agent SDK, that fans out parallel reasoning branches, scores them, and develops the most promising for planning tasks. Outside experts questioned the "2x better" claim and said the approach resembles existing paralle...
A software engineering guide identifies five common pitfalls in modular AI architecture: over-modularizing early, inconsistent feature engineering across modules, and related design errors that cause latency increases and data inconsistencies. Recommended fixes include grouping components by chan...
A developer documented setting up Rails user authentication with the Devise gem, using AI coding assistants including Claude Code and FirstDraft Co-pilot. They noted Claude Code consumed tokens rapidly by re-reading full files, prompting a shift to writing more code manually and reserving Claude ...
AiFinPay released a Python SDK ("aifinpay-agent") designed to add payment processing capabilities to autonomous AI agents, and announced a partnership with ruvnet/ruflo, an AI agent orchestration platform.
Contorium Labs released Contorium, an open-source runtime continuity layer for AI coding agents that tracks workspace state, git state, and session context across sessions. It is compatible with Cursor, VS Code, Claude Code, Codex, and MCP-based agents, and does not use chat history for state per...
Anthropic's Claude Code shipped updates in April raising the per-tool MCP output limit to 500,000 characters, adding concurrent server connections, tool search, and lazy loading. The changes allow MCP memory servers to return fuller context payloads per tool call instead of truncating responses t...
A developer released Rein, an open-source tool for Claude Code that monitors AI agent sessions to detect patterns indicating missing scaffolding — such as repeated bugs, context loss, or cost spikes — based on a framework the author calls "Harness Engineering."
A benchmark of local Qwen models on an RTX 3090 Ti running llama.cpp against Anthropic's Claude API found 4.3x–9.3x latency speedups on Haiku-tier JSON workloads, with quality scores at or near Anthropic-vs-Anthropic ceiling per an Opus LLM-as-judge metric across 100 trials.
Product designer Hardik Pandya released "stop-slop," an MIT-licensed Markdown skill file for Claude and other AI tools that identifies and removes common AI writing patterns across 8 categories, using a 5-dimension scoring rubric. The project has accumulated over 5,800 GitHub stars and 435 forks.
Anthropic, AWS, and Google each launched managed AI agent runtimes within six weeks, with Anthropic's Claude Managed Agents entering beta on April 8, AWS updating Bedrock AgentCore on April 22, and Google announcing Managed Agents in the Gemini API at Google I/O. All three use configuration files...
A developer published details of a service called MCP Agent Exchange, a marketplace where developers can register AI agents at a set price per API call and retain 85% of revenue, with a 5% perpetual referral commission for recruiting other developers.
SQLite added an AGENTS.md file stating it does not accept AI-generated code, later strengthening the language by removing the qualifier "currently." The project also created a separate bug forum after its main forum was flooded with AI-generated bug reports of varying quality.
Cisco has partnered with OpenAI to deploy Codex, an AI coding assistant, for software development tasks including automated defect remediation and work on Cisco's AI Defense product line.
Anthropic and OpenAI both switched enterprise AI coding tool pricing from flat-rate seat licenses to API token-based billing — Anthropic in November 2025 and OpenAI in April 2026 — resulting in unexpectedly large bills for corporate customers. Anthropic is reportedly approaching its first profita...
Cognition, an AI coding startup, raised $1 billion at a $25 billion pre-money valuation, more than doubling its valuation in eight months. The company reported $492 million in annualized revenue run rate.
