Runs the open skills CLI and installs the skill for your agent (Claude Code, Codex, Cursor …). Alternatively copy the skill folder into .claude/skills/ or upload it in Claude.ai under Settings → Skills.
As a Claude Code plugin
/plugin marketplace add anthropics/claude-plugins-official
/plugin install postman@postman
This skill is part of the plugin “postman”. In Claude Code the plugin installs it together with the plugin’s other skills, commands and hooks.

Questions about datasets
What does the datasets skill do?
Use when creating or repairing dataset manifests, or when a collection needs queried or joined test inputs, a reusable named view, spreadsheet worksheet data, live database rows, or script access through pm.datasets(). Chooses between a simple iteration file and a dataset while preserving query semantics, portability, and credential boundaries. Use for requests such as "run this collection over database rows".
How do I install datasets?
In a terminal: npx skills add postmanlabs/postman-plugin --skill datasets. The skills CLI asks which agents to install it for. In Claude.ai you can upload the skill folder as a ZIP under Settings → Skills.
Which agents can use datasets?
Skills use the open SKILL.md format, which Claude Code, Claude.ai, the Claude API, OpenAI Codex, Cursor, Gemini CLI and other agents support.
Is datasets safe to use?
Our automatic check found no risky patterns (piped shell scripts, hidden characters, secret access, prompt overrides). It is not a full audit – read the SKILL.md and any scripts before installing.

Use when load-testing or benchmarking an API with concurrent virtual users and latency or error thresholds, or when importing or migrating a JMeter `.jmx` plan or a Gatling simulation (Java/Kotlin/Scala/JS/TS) into a Postman collection plus a `postman performance run` configuration. Reuses a collection to probe a chosen failure mode and distinguishes target limits from load-generator limits. Use for requests such as "load test this API", "import my JMeter plan", or "convert my Gatling project to Postman".
Sets up, runs, debugs, and interprets results from `postman application test` — the Postman layer that runs your Playwright tests, captures their network traffic, matches it against a collection contract, runs pm.test assertions, and publishes results to Application Inventory. Covers the Postman side of the integration only — not Playwright test authoring or Playwright failures unrelated to capture. Use when the user asks to "set up application testing," "test my application with Postman," "connect my Playwright tests to Postman," "capture network traffic from Playwright," "Playwright tests are running but nothing shows up in Postman," "why isn't application testing capturing anything," "exclude certain requests from capture," "generate a collection from my app's traffic," "set up application testing in CI," "what API coverage do my e2e tests have," "which APIs are my Playwright tests not hitting."
Use when adding API tests, structural or governance lint, or AI-readiness gates to CI, or publishing reviewed API artifacts to a Postman workspace after merge. Makes contract checks repeatable and separates validation from shared workspace changes. Use for requests such as "run this collection on every PR".
Use when writing or debugging local Postman v3 collection, environment or globals files, including collection lint failures. Preserves the per-entity files, inherited context, and schema shapes that make API changes reusable and reviewable in Git. Use for requests such as "fix this request YAML".
Use when running, deploying, or debugging an existing Postman Flow. Distinguishes local graph execution from a deployed webhook, reuses named input scenarios, and follows a run to the failing block rather than treating an HTTP response as whole-flow success. Use for requests such as "why did this flow fail".
Use when parameterizing requests across environments, choosing variable scopes, chaining values in scripts, or referencing credentials without committing or exposing them. Keeps one reusable collection while separating target configuration from secret values. Use for requests such as "where should I put this API key".
Use when initializing Postman in a repository, binding it to a Postman workspace, interpreting what `postman init` did, or handling CLI-suggested actions for authentication, plan, credits, usage quota, or subscription restrictions. Treats the workspace as the place where a service's API work and its evidence live, kept separate from the services it depends on. Use for requests such as "set up Postman in this repo" or "connect this repo to our workspace".
Capture, forward to localhost, replay, and validate webhook deliveries using a reusable public URL. Keep sender configuration across debugging sessions and record arrivals even while local forwarding is stopped, helping distinguish delivery failures from local connectivity issues. Use for implementing or debugging incoming handlers and testing webhooks an API sends, whether or not Postman is mentioned. Example requests include "get payment events to localhost," "inspect a webhook delivery," and "replay an event after a fix"; these illustrate intent, not an exhaustive list or exact phrases to match.

Postgres best practices maintained by Supabase, for Postgres running anywhere. Load this skill BEFORE writing or changing anything that lives in a Postgres database: creating or altering tables and columns (including choosing column types), schema design, migrations and declarative schema files, RLS policies and the tests that verify them, indexes, triggers, database functions, queues and scheduled jobs (pg_cron, pgmq), vector/semantic search (pgvector), and restoring dumps (pg_restore) or importing data. Also load it when diagnosing slow queries, high CPU, timeouts, EXPLAIN plans, connection exhaustion, locking, bloat, or rows visible to the wrong user or tenant. This is not just a performance guide — schema, migration, security, and SQL authoring tasks need these rules too, even for a one-column change or a single query.
Deprecated compatibility name for prisma-orm-setup. Use only when a user or existing integration explicitly invokes prisma-database-setup; otherwise select prisma-orm-setup.
Deprecated compatibility name for prisma-postgres-setup. Use only when a user or existing integration explicitly invokes prisma-postgres; otherwise select prisma-postgres-setup.
Obtain or reuse a Prisma Postgres database and connect an application. Use when the user needs a database and has none configured ("I need a database", "add a Postgres database", "set up a database for this app"), runs or mentions `create-db` or `npx create-db`, or asks to set up or connect Prisma Postgres, including in v0 and the Vercel Marketplace. Hands Prisma ORM configuration to prisma-orm-setup; reuses an existing connection first and honors an explicit provider, driver, alternative ORM, or database-only choice.
Required reference for Prisma ORM 7 SQL driver adapter work. Use when implementing or modifying adapters, adding database drivers, or touching SqlDriverAdapter, Transaction, savepoint, result mapping, or DriverAdapterError behavior. Covers current transaction lifecycle, optional savepoint hooks, original database-error preservation, and verification.
Use when doing ANY task involving Supabase. Triggers: Supabase products (Database, Auth, Edge Functions, Realtime, Storage, Vectors, Cron, Queues); client libraries and SSR integrations (supabase-js, @supabase/ssr) in Next.js, React, SvelteKit, Astro, Remix; auth issues (login, logout, sessions, JWT, cookies, getSession, getUser, getClaims, RLS); Supabase CLI or MCP server; schema changes, migrations, declarative schemas, security audits, Postgres extensions (pg_graphql, pg_cron, pg_vector); debugging and troubleshooting errors or unexpected behavior on Supabase projects (HTTP errors, Postgres errors, RLS surprises, permission denied, schema cache issues, timeouts, Edge Function crashes, Realtime drops, Storage failures) and reading or querying logs (Logs Explorer, ClickHouse).
Set up Prisma ORM in an application, connect its database, or troubleshoot the connection of an existing Prisma 6, 7, or 8 app. Defaults new applications to Prisma ORM 8 and loads the package-owned prisma-8 skill; keeps existing Prisma 6/7 apps on their version with provider references for PostgreSQL, MySQL, SQLite, SQL Server, CockroachDB, MongoDB, and Prisma Postgres.
