Quick router to the right Effect skill based on your coding task.
Works with
Organized decision tree with 12 focused skills covering Effect fundamentals, error handling, concurrency, streams, dependency injection, HTTP, validation, data structures, logging, queues, and testing
Cross-skill pattern references linking common workflows (retries, resource management, graceful shutdown, service design) to both relevant skills and the 130+ pattern examples in the Patterns Hub
Local Effect source code
AI-first code editor with Composer
Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versioneffect-indexExecute the skills CLI command in your project's root directory to begin installation:
Fetches effect-index from mepuka/effect-ontology and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate effect-index. Access via /effect-index in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Use this as a quick router to the right Skill for your task. Each entry links to a focused Skill optimized for a coding agent’s limited context.
All patterns are now available locally in the Patterns Hub (130+ patterns):
Tip: For any "How do I...?" question, check the Patterns Hub decision tree first!
CRITICAL: Always search local Effect source before implementing
The full Effect source code is available at docs/effect-source/. Every Effect skill now includes a "Local Source Reference" section with:
docs/effect-source/docs/effect-source/effect/src/docs/effect-source/platform/src/docs/effect-source/sql/src/docs/effect-source/schema/src/grep -F "Effect.gen" docs/effect-source/effect/src/Effect.ts

Steps
Common Pitfalls
✓ Do
✗ Don't
💡 Pro Tips
✓ Use when
Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.
✗ Avoid when
Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.

effect-index reduced setup friction for our internal harness; good balance of opinion and flexibility.
I recommend effect-index for anyone iterating fast on agent tooling; clear intent and a small, reviewable surface area.
Solid pick for teams standardizing on skills: effect-index is focused, and the summary matches what you get after install.
Useful defaults in effect-index — fewer surprises than typical one-off scripts, and it plays nicely with `npx skills` flows.
effect-index has been reliable in day-to-day use. Documentation quality is above average for community skills.
Registry listing for effect-index matched our evaluation — installs cleanly and behaves as described in the markdown.
effect-index fits our agent workflows well — practical, well scoped, and easy to wire into existing repos.
We added effect-index from the explainx registry; install was straightforward and the SKILL.md answered most questions upfront.
