api-simulation

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".

Use when the Postman CLI is missing or can't be installed, or when `postman` is "command not found". Installs the CLI globally so `postman` is on `PATH`, with a fallback to the hosted MCP server when installing is blocked. Use for requests such as "install the Postman CLI".

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 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".

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.

Scan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick.

Diagnosis loop for hard bugs and performance regressions. Use when the user says "diagnose"/"debug this", or reports something broken/throwing/failing/slow.

Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes: Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/spec asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to "review since X".

Investigate a question against high-trust primary sources and capture the findings as a Markdown file in the repo. Use when the user wants a topic researched, docs or API facts gathered, or reading legwork delegated to a background agent.
