What it does

Blockless Extension E2E is an agent skill from FreakStudioCN/mpy-hardware-extension. Run and debug the Blockless VS Code extension release gate: CI-equivalent API and extension tests, V0 protocol smoke, live DeepSeek full-stack e2e, VSIX packaging, local reinstall, direct push-to-main verification, and GitHub Actions follow-up. Use when working in cursorforhardware/mpy-hardware-extension, when CI is failing, when the user asks to run e2e, push main, reinstall the plugin, or verify the extension against docs without editing extension docs.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `agents/openai.yaml`).

It sits in Testing & QA, covering End-to-end testing. It works with DeepSeek, GitHub Actions, Visual Studio Code and npm.

When your agent uses it

  • Working in cursorforhardware/mpy-hardware-extension
  • The user asks to run e2e
  • Reinstall the plugin
  • Verify the extension against docs without editing extension docs

Example prompts

  • “/blockless-extension-e2e”

Requirements

  • Python 3
  • PowerShell
  • Docker
  • A credential in DEEPSEEK_API_KEY

Workflow steps

9 steps, taken from the first numbered list in SKILL.md.

  1. Recreate isolated database mpyhw_test in Docker container mpyhw-pg.
  2. API job environment: set only DATABASE_URL=postgresql://postgres:mpyhw@127.0.0.1:55432/mpyhw_test; remove dev overrides like…
  3. Run python -m pytest in mpyhw-api.
  4. Run npm run build in mpy-hardware-extension.
  5. Recreate mpyhw_test again, then run npm test with MPYHW_REQUIRE_CONTRACT_TESTS=1.
  6. Run npm run test:v0 with MPYHW_REQUIRE_CONTRACT_TESTS=1.
  7. Run npm run typecheck.
  8. Run python -m pytest in mpy-hardware-extension/python/shim.
  9. Run npm run package.

What it can do on your machine

Read from SKILL.md and the folder at commit b661df6. 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

    Ships 1 file in scripts/ (PowerShell), which the agent can run.

    Shell commands in SKILL.md call:

    • npm
    • git
    • node
    • python
    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use npm, git and gh, which can reach the network depending on how they are called.

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • DEEPSEEK_API_KEY

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

Context cost

Blockless Extension E2E loads about 1.2k tokens when it runs. Until then it costs about 121 tokens; SKILL.md has 459 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~121
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:49
    If API pytest fails only when `.env` was loaded, compare with CI environment before changing code. The dev `.env` may co
  • NoteMentions a .env fileSKILL.md:55
    :<port>` with env loaded from `mpyhw-api/.env`.

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); the scripts in this folder 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 459 words (~1,200 tokens).
