Callstack Agent Skills - Setup Guide¶

Source: callstackincubator/agent-skills (1,663⭐, MIT LICENSE; very active - pushed Oct 6, 2026) Skill family: callstackincubator/agent-skills (13 SKILL.md files in-repo; 15 indexed listings) Combined Installs: ~80,715 across indexed listings (Oct 7, 2026 snapshot) Category: Mobile Development / React Native Quality Tier: 🟡 Beta (official Callstack incubator org, active since 2018; MIT LICENSE in-repo; very active development; sampled security verdicts predominantly Pass - verified Oct 7, 2026)

Callstack Agent Skills give AI coding assistants practical React Native knowledge drawn from Callstack's production work on real apps. The suite ships as three plugin bundles - Building React Native Apps, Testing React Native Apps, and Migrating to React Native - covering performance profiling and optimization, navigation (React Navigation 7), TV app development, library authoring with create-react-native-library, framework upgrades, CI builds (downloadable iOS simulator and Android emulator artifacts via GitHub Actions), device automation and exploratory QA, migration readiness assessment, and incremental brownfield adoption via @callstack/react-native-brownfield. Several skills derive from Callstack's published reference material, including the "Ultimate Guide to React Native Optimization".

Installation¶

# Full suite (all Callstack skills)
npx skills add callstackincubator/agent-skills --skill '*'

# Or pick a single skill
npx skills add callstackincubator/agent-skills --skill react-native-best-practices

Claude Code and Codex users can install the three bundles from their plugin marketplaces (plugins/building-react-native-apps, plugins/testing-react-native-apps, plugins/migrating-to-react-native). The skills are host-neutral Agent Skills (skills/<name>/SKILL.md) and can be pointed at any host's skill installer.

CorpusIQ Use Cases¶

Use Case	How
Agent-suite packaging pattern	Three themed bundles built from one company's domain expertise, with verify-oriented pairs and vendored open-source skills - a strong reference for how product teams structure skill libraries
Mobile teams working with AI assistants	Teams shipping React Native apps get measurement-first performance work, guided upgrades, CI artifact builds, and migration planning from an assistant that knows current framework idioms
Enterprise migration evaluations	The migration pair (assess plus brownfield) turns "should we adopt React Native?" into an auditable, checkpoint-based plan - useful when operators evaluate mobile stack changes

Integration with CorpusIQ¶

CorpusIQ is the connector layer that lets AI assistants read the systems a business already runs on - accounting, payments, CRM, email, files and analytics - and answer with the source named. It is read-only by design: it retrieves data and never writes to, or acts in, a connected system, which is what makes it safe to point at live accounts.

This page is part of the CorpusIQ directory, the reference we maintain for the MCP server and agent-skill ecosystem. Run alongside CorpusIQ, a third-party server like this one can be combined with a company's own business data in a single answer.

Limitations / Verification¶

Verified Oct 7, 2026: 13 SKILL.md files via the GitHub trees API on branch main (9 first-party under skills/, 1 tooling skill under .claude/skills/, 3 vendored under plugins/vendored/); 1,663 stars; MIT LICENSE in-repo; last pushed Oct 6, 2026; publisher is Callstack's incubator org (callstackincubator, created June 2018, 48 public repos, callstack.com).
First seen in the July 27-28, 2026 sweeps and deferred then as below-floor and platform-specific; re-qualified Oct 7, 2026 at ~80,715 combined listed installs, roughly 4x its July size.
React Native-specific: useful for RN and mobile teams, not a general-purpose suite. The three vendored skills mirror publications from callstackincubator/agent-device and callstack/react-native-testing-library.
Skills operate on live development projects (upgrades, CI workflows, migration steps, device automation). Review commands before running them against production repos or CI secrets.
No live install test was performed; install counts are the Oct 7, 2026 skills.sh sweep snapshot.
