Per-IDE setup walkthroughs for using @mongez/agent-kit with Claude Code, Cursor, Codex, Kiro, Gemini CLI, GitHub Copilot, Aider, and Antigravity. Each walkthrough shows the exact files agent-kit creates, the --target flag to pass, the reload quirks, and a copy-pasteable package.json snippet.
How to author and lay out skills for agent-kit — both your project's own skills in a single nested skills/ folder at the project root, and reusable skills shipped from an npm package. Covers folder layout, nested category organization, SKILL.md frontmatter (description, name), the files field, flat destination naming…
The agentKit config block in package.json for @mongez/agent-kit — every field and how it resolves: targets (default skill-sync agents), pick (allowlist) and omit (denylist) for filtering noisy dependency skills, and monorepo.projects for aggregating sibling projects. Covers pick-then-omit ordering, per-project config…
Using @mongez/agent-kit in a monorepo / full-stack repo where one session at the root must see skills from sibling projects (backend, frontend, …). Covers --projects / agentKit.monorepo.projects aggregation, the difference from --path, per-project nodemodules + per-project agentKit config, project-dir-prefixed…
What agent-kit is, what it does, and when an agent should reach for it — the front-door mental model covering AGENTS.md derivation, npm-package skill distribution, custom --path scan roots (monorepos / linked dev packages), nested skill folders, flat folder naming ( - ), and the .agent-kit-managed sentinel.
Cross-feature wiring patterns for @mongez/agent-kit — per-workspace AGENTS.md in a monorepo, pick/omit filtering when a dependency ships skills you don't want, a CI guardrail that fails if the derived files drifted, the programmatic API for non-CLI pipelines, and watch mode for active development.
Symptom → cause → fix for the common @mongez/agent-kit problems: agent-kit: command not found, unscoped npx agent-kit fetching the wrong package, skills synced but the agent doesn't see them, agentKit.pick matched no installed packages, two-package slug collision, sync errors on missing AGENTS.md, a published…
