What it does

Local Stack Runtime is an agent skill from OpenHands/OpenHands. This skill should be used when the user asks to "change the dev stack", "add a runtime service", "change the launcher", "update Docker", "bump Agent Server", "change ingress routing", or changes scripts/dev-.mjs, runtime-services metadata, config/defaults.json, Docker, automation startup, process shutdown, or local authentication.

Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/guide.md`).

It sits in DevOps & Cloud, covering Cloud networking and Containers. It works with Docker and OpenAI. The repository describes itself as: 🙌 OpenHands: AI-Driven Development. The licence is MIT.

When your agent uses it

  • Asks to change the dev stack
  • Add a runtime service
  • Change the launcher
  • Bump Agent Server

Example prompts

  • “change the dev stack”
  • “add a runtime service”
  • “change the launcher”
  • “/local-stack-runtime”

Requirements

  • Docker

Workflow steps

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

  1. Read references/guide.md before changing launchers, runtime service metadata, version pins, Docker composition, auth generation, or…
  2. Treat config/defaults.json and the injected block as authoritative.
  3. Preserve coordinated process-tree shutdown and fail fast on missing prerequisites.
  4. Keep Agent Server and automation versions compatible and authentication keys correctly scoped.
  5. Update documentation and version-drift tests when changing pins or launch commands.
  6. Validate each affected launch mode rather than assuming Vite, static, npm, Docker, and Electron behave identically.

What it can do on your machine

Read from SKILL.md and the folder at commit baf1cbe. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Local Stack Runtime loads about 375 tokens when it runs, and up to ~4.2k if it reads all its reference files. Until then it costs about 88 tokens; SKILL.md has 132 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~88
When it runs · the whole SKILL.md, loaded when a task matches
~375
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.2k

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 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.

description
This skill should be used when the user asks to "change the dev stack", "add a runtime service", "change the launcher", "update Docker", "bump Agent Server", "change ingress routing", or changes scripts/dev-*.mjs, runtime-services metadata, config/defaults.json, Docker, automation startup, process shutdown, or local authentication.

Local Stack and Runtime Services

Maintain the shared configuration and launch plumbing across Vite/static development, Agent Server, automation, ingress, the published binary, and the all-in-one Docker image.

Workflow

  1. Read references/guide.md before changing launchers, runtime service metadata, version pins, Docker composition, auth generation, or process management.
  2. Treat config/defaults.json and the injected <RUNTIME_SERVICES> block as authoritative.
  3. Preserve coordinated process-tree shutdown and fail fast on missing prerequisites.
  4. Keep Agent Server and automation versions compatible and authentication keys correctly scoped.
  5. Update documentation and version-drift tests when changing pins or launch commands.
  6. Validate each affected launch mode rather than assuming Vite, static, npm, Docker, and Electron behave identically.

Reference

  • references/guide.md — Runtime-services schema and prompt plumbing, launcher environment variables, ingress routes, version synchronization, security, Docker build architecture, README synchronization, and spec-tag conventions.
