Claude Code & ant CLI

Source: docs.anthropic.com (May 2026)

5 configs

Anthropic's CLI execution environment. Updated with 1-hour prompt caching controls, 'Monitor' tools, and the new `ant` YAML CLI setup. Now supporting Claude Opus 4.7.

.ant.yaml

▾

Configuration file for the new `ant` CLI tool released in April 2026. Manages fast environments and agent versions.

CLAUDE.md

▾

Project memory — read at every session start. Keep under 200 lines. Optimized for the 1M token context limit.

.claude/settings.json

▾

Permissions, hooks, and behavior control. Project-level (committed to git). Use settings.local.json for personal overrides (gitignored).

.claude/agents/security-reviewer.md

▾

Custom sub-agent — specialized AI persona invoked for specific tasks. Upgraded to Claude Sonnet 4.7.

.claude/.mcp.json

▾

MCP server config for Claude Code sessions. Defines which MCP servers are available. Project-scoped (committed) or global (~/.claude/.mcp.json).

Anthropic API & Managed Agents

Source: Anthropic API Docs (May 2026)

1 configs

Beta configurations for the new 2026 Managed Agents API and Advisor Tool API, providing robust sandboxed execution natively from the cloud. Updated for Opus 4.7.

src/agents/client.ts

▾

Initialization snippet using the new 2026 Managed Agents API Beta headers and Claude Opus 4.7.

🖱️

Cursor

Source: cursor.com/docs, cursor.directory

2 configs

AI-native code editor. Uses .cursor/rules/ folder with .mdc files (Markdown Context) for modular, glob-filtered rules.

.cursor/rules/project-context.mdc

▾

Always-on project context. Tells Cursor what your stack is, so it generates code matching your exact setup.

.cursor/rules/typescript-standards.mdc

▾

Scoped to TypeScript/TSX files only via glob pattern. Enforces type safety rules.

🤖

GitHub Copilot

Source: docs.github.com, code.visualstudio.com

1 configs

GitHub's AI pair programmer in VS Code. Uses .github/copilot-instructions.md for project-wide rules and .github/instructions/ for path-specific overrides.

.github/copilot-instructions.md

▾

Project-wide Copilot instructions — automatically applied to all suggestions and chat interactions. Commit to git for team-wide standards.

✦

Gemini CLI & Antigravity

Source: geminicli.com, Google DeepMind docs

2 configs

Google's AI coding tools. Gemini CLI for terminal workflows, Antigravity for IDE agent sessions. Both read GEMINI.md for context.

GEMINI.md

▾

Project context file — equivalent to CLAUDE.md. Read at session start. Place at project root or ~/.gemini/GEMINI.md for global rules.

.gemini/settings.json

▾

Project-level Gemini settings. Controls model, permissions, and behavior. ⚠️ Warning: If you use both Gemini CLI and Antigravity, they share ~/.gemini/GEMINI.md — be careful of config pollution.

🏄

Windsurf (Cascade)

Source: windsurf docs, dev.to

1 configs

Agentic IDE powered by Cascade. Uses .windsurfrules (legacy) or .windsurf/rules/ folder for modular configs. Keep rules under 6,000 characters to avoid truncation.

.windsurfrules

▾

Legacy single-file rules — simple and effective. Place at project root. For larger projects, migrate to .windsurf/rules/ folder.

May 2026: The Agentic Shift

AI coding workflows have transitioned from generic conversational chat into fully autonomous, execution-based agentic patterns. Toolsets like Claude Code leveraging the .ant.yaml CLI and the managed-agents-2026-04-01 API headers emphasize 1M context limits, sandbox integration, and verifiable output.

Whether you are leveraging the new Claude Opus 4.7 APIs or migrating from legacy single-file rules to modular MDCs in Cursor, your enterprise architecture requires robust "onboarding documents". They instruct these models precisely on architecture, typing constraints, and guardrails to prevent security regressions during fast execution cycles.

This toolkit maintains the definitive standard for May 2026, presenting 12 production-ready arrays of knowledge for these cutting-edge sandboxes. Copy the blocks, execute safe iterations, and accelerate your engineering capabilities cleanly.
