grpcurl-cli SKILL.md skillA

grpcurl-cli from testland/qa is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add testland/qa/grpcurl-cli@git:20261011.a1bd3f7

Pins git:20261011.a1bd3f7 in mdr.lock. Pin the fingerprint instead.

Wraps grpcurl, the curl-equivalent CLI for gRPC. Covers descriptor sources (server reflection default, --import-path + --proto for proto files, --protoset for compiled descriptor sets), service discovery (`list`, `describe`), invoking unary RPCs (`-d '{...}'`, `-d @file.json`, `-d @` for stdin), streaming RPCs (newline-delimited JSON via stdin), TLS configuration (--cacert, --cert, --key, --insecure, --plaintext), header injection (-H 'Authorization: Bearer ...'), and exit codes. Use for…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# grpcurl-cli

## Overview

Per
[github.com/fullstorydev/grpcurl](https://github.com/fullstorydev/grpcurl/blob/master/README.md),
grpcurl can invoke any gRPC method using one of three descriptor
sources (server reflection, `.proto` source files, or compiled
`.protoset` files) and emits JSON responses. This skill wraps
grpcurl for: ad-hoc debugging, scriptable smoke tests, and
CI-based contract verification.

## When to use

- Manually exercising a gRPC server during development.
- Smoke test in CI: "can the deployed server respond to this RPC?"
- Reproducing a production bug locally before writing a test.
- Inspecting a third-party gRPC service that supports reflection.
- Verifying gRPC-to-HTTP gateway behaviour by comparing grpcurl
  + HTTP curl side by side.

## Authoring

### Install

Per [grpcurl README](https://github.com/fullstorydev/grpcurl/blob/master/README.md):

```bash
# Homebrew
brew install grpcurl

# Go install
go install github.com/fullstorydev/grpcurl/cmd/grpcurl@latest

# Docker
docker pull fullstorydev/grpcurl:latest
```

Verify:

```bash
grpcurl -version
```

How to install

The exact contents, by fingerprint

mdr add testland/qa/grpcurl-cli@sha256:6b03710e5e6f9bd7

The line at the top of this page pins the label git:20261011.a1bd3f7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
