Generate hybrid cloud tests for the Sentry codebase. An agent skill from getsentry/sentry.

  • Works in 7 steps: Identify Test Category → Gather Context → Generate RPC Service Tests → …
  • Asked to generate HC test
  • SKILL.md covers Critical Constraints, Step 1: Identify Test Category, Step 2: Gather Context and Step 3: Generate RPC Service…, plus 6 more sections
  • Calls pytest

What it does

Hybrid Cloud Test Gen is an agent skill from getsentry/sentry, published by the product's own GitHub organization. Generate hybrid cloud tests for the Sentry codebase. Use when asked to "generate HC test", "create hybrid cloud test", "write HC test", "add HC test", "write RPC test", "test RPC service", "silo test", "cross-silo test", "outbox test", "API gateway test", or "endpoint silo test". Covers RPC service tests, API gateway tests, outbox pattern tests, and API endpoint tests with silo decorators.

Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/api-gateway-tests.md`, `references/endpoint-silo-tests.md` and `references/outbox-tests.md`).

It sits in Backend & APIs, covering Microservices, Integration testing and REST APIs. It works with Sentry. The repository describes itself as: Developer-first error tracking and performance monitoring.

When your agent uses it

  • Asked to generate HC test
  • Create hybrid cloud test
  • Test RPC service
  • Cross-silo test

Example prompts

  • “generate HC test”
  • “create hybrid cloud test”
  • “write HC test”
  • “/hybrid-cloud-test-gen”

Requirements

  • Python 3

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Identify Test Category
  2. Gather Context
  3. Generate RPC Service Tests
  4. Generate API Gateway Tests
  5. Generate Outbox Pattern Tests
  6. Generate Endpoint Silo Tests
  7. Validate

What it can do on your machine

Read from SKILL.md and the folder at commit 99b4c2b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pytest

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Hybrid Cloud Test Gen loads about 2.6k tokens when it runs, and up to ~8.1k if it reads all its reference files. Until then it costs about 104 tokens; SKILL.md has 742 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~104
When it runs · the whole SKILL.md, loaded when a task matches
~2.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 742 words (~2,570 tokens).

“This skill generates tests for Sentry's hybrid cloud architecture. It covers RPC services, API gateway proxying, outbox patterns, and endpoint silo decorators.”
