#Developer Tools

A production implementation guide to OpenAI async tool calling, covering the Responses API contract, durable job registries, late-result delivery, failure recovery, wait tools, and compatibility limits.

A current implementation guide to GitHub Copilot content exclusions, including CLI and app support, pattern syntax, policy scope, REST auditing, testing, and documented limitations.

A practical administrator checklist for GitHub Copilot's September 2026 policy convergence, longer chat retention, Balanced code-review default, and October seat-billing changes.

A production guide to starting GitHub Copilot cloud-agent work from Slack while keeping conversation context, repository permissions, app identity, review rules, and cost controls explicit.

A practical security guide to enabling VS Code agent sandboxing, limiting filesystem and network access, controlling elevation, and testing the resulting policy.

A production guide to packaging Agent Skills and MCP servers with Agent Plugins 1.0 while keeping client-specific behavior, secrets, and trust controls explicit.

A practical migration plan for the stateless MCP release candidate, covering request metadata, explicit state handles, caching, retries, deprecated features, and staged rollout.

A practical breakdown of GitHub Copilot's new AI Credits billing — how tokens convert to dollars, what every plan includes, and how to keep one agent session from eating your month's allowance.

A practical guide to securing remote MCP servers with OAuth 2.1-style discovery, PKCE, resource-bound tokens, token validation, and production-safe scopes. Includes a checklist, runnable Express middleware, and the failure modes developers usually miss.

A practical guide to writing CLAUDE.md as a permission contract for AI coding agents, covering tool tiers, hard stops, failure behavior, and MCP server security.

AI is generating more pull requests than humans can review. The fix isn't picking the best AI code review tool — it's combining the right ones.

Gemini CLI shipped subagents in April 2026. Here is an architectural comparison with Claude Code covering orchestration, context capacity, and permission controls.

Claude Code's Monitor tool streams background process output directly into the agent session, replacing polling loops with event-driven reactions that cost nothing during idle periods.

GitHub's new gh skill command brings npm-style package management to AI agent skills for Copilot, Claude Code, Cursor, and Codex — but 36.82% of public skills carry security issues. Here's how to use it safely.

Anthropic has released Claude Opus 4.6 with a 1 million token context window, Agent Teams for parallel coding agents, and the discovery of 500+ zero-day vulnerabilities during testing. Here's a deep dive into what makes this release fundamentally different.

OpenAI has officially launched Codex, a native macOS application that serves as a command center for managing multiple AI coding agents. Here's everything developers need to know about Skills, Automations, pricing, and how it compares to Cursor, Copilot, and Replit.
