Agent Skills

io.github.utmapp/UTM/utm-review

Review pending UTM changes before they are submitted. Runs a standard correctness/quality code review of the current branch's diff AND audits it against UTM's contribution rules in CONTRIBUTING.md and AGENTS.md — scope discipline, commit/PR format, AI attribution, logging hooks, generated files, UI/design philosophy, and platform compatibility. Use this before opening or updating a UTM pull request, whenever the user asks to review UTM changes, or when the user runs /utm-review. The /utm-submit workflow expects this to have been run on the current changes first.

io.github.nexu-io/open-design/agent-browser

Browser automation CLI for AI agents. Use when the user needs to inspect, test, or automate browser behavior: navigating pages, filling forms, clicking buttons, taking screenshots, extracting page data, reading selected Open Design browser-tab context, testing web apps, dogfooding Open Design previews, QA, bug hunts, or reviewing app quality. Prefer local Open Design preview URLs unless the user explicitly asks for external browsing.

io.github.mohitagw15856/pm-claude-skills/database-migration-plan

Write a safe, zero-downtime database migration plan for a schema change. Use when asked to plan a database migration, design a zero-downtime schema change, document an expand/contract migration, produce a rollback procedure for a database change, or coordinate a database schema update with a deployment. Produces a structured migration plan covering migration objectives, backward compatibility analysis, expand/contract phase breakdown, exact SQL, rollback steps per phase, data validation queries, and a deployment runbook.

io.github.mohitagw15856/pm-claude-skills/database-schema-design

Document or design a database schema with entity relationships, table definitions, constraints, indexes, and access patterns. Use when asked to design a database, document an existing schema, model entities and relationships, define table structures, plan an index strategy, or produce a data model for review. Produces a structured schema document covering an ER diagram, table DDL definitions, index strategy, access pattern analysis, normalization decisions, and migration notes.

io.github.mohitagw15856/pm-claude-skills/sql-query-explainer

Explains, optimises, writes, and documents SQL queries. Use when asked to explain a SQL query, optimise slow SQL, translate SQL to plain English for non-technical stakeholders, write a query from a natural language description, or produce query documentation. Produces plain-English explanations, annotated optimised queries, or a data dictionary covering output shape, assumptions, and known limitations. Works across PostgreSQL, MySQL, BigQuery, Snowflake, and standard SQL.

io.github.langfuse/langfuse/code-review

Shared code review workflow for Langfuse. Use when reviewing a PR, branch, diff, or local changes for correctness, regressions, risk, and missing tests. Start with references/review-checklist.md for repo-specific review rules and use package AGENTS.md files plus any matching shared skills when the change touches those areas.

io.github.langfuse/langfuse/security-review

Security review patterns for Langfuse. Use during code review, design, or planning whenever a change accepts user-supplied URLs, host/endpoint/baseURL fields, secrets, cross-tenant data, new outbound HTTP requests, new integrations (webhooks, blob storage, LLM connections, image proxies), redirect-following behavior, or new auth/permission scopes. Covers SSRF/outbound URL validation today and is intentionally extensible to other recurring security findings (tenant isolation, secret handling, redirect mishandling, file upload, RBAC scope drift).

io.github.orangehrm/orangehrm/testing

Reference for OrangeHRM's test layers — PHPUnit per-plugin testsuites declared in `phpunit.xml`, the test-DB lifecycle (`instance:create-test-db` builds a populated MySQL DB plus a `CoreFixtureService` dump that bootstrap restores per test), test base classes (`TestCase` for plain unit tests, `KernelTestCase` for tests that need the full framework + DI container, `EntityTestCase` for entity-only tests, `EndpointTestCase` and `EndpointIntegrationTestCase` for API endpoint tests with request mocking + exception expectations), the YAML fixture pattern (per-plugin `test/fixtures/<DaoName>.yml` + `TestDataService::populate($yamlPath)` in `setUp()`), Jest configuration for frontend unit tests (`@vue/cli-plugin-unit-jest/presets/typescript-and-babel`, `__tests__/` siblings), and Cypress for E2E (separate workspace under `src/test/functional/`).
