What it does

Deploy is an agent skill from virtualcell/vcell. Cut a VCell release and deploy it — pick the next version, write the changelog, tag + GitHub release (triggers the CI-full image build), then CD-sites to a site (alpha→dev namespace, rel→prod, test→stage). Use when asked to "deploy to alpha/dev/prod/stage", "cut a release", or "bump the version and deploy".

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Changelog and release notes. It works with GitHub. The repository describes itself as: Virtual Cell Framework.

When your agent uses it

  • The CI-full image build)
  • Then CD-sites to a site (alpha→dev namespace
  • Asked to deploy to alpha/dev/prod/stage
  • Bump the version and deploy

Example prompts

  • “deploy to alpha/dev/prod/stage”
  • “cut a release”
  • “bump the version and deploy”
  • “/deploy”

Requirements

  • Docker

Workflow steps

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

  1. Preconditions. master is green: CI passed on the merge, and
  2. Release-cut docs (per docs/RELEASING.md): add a ## [X.Y.Z.BB]
  3. Tag + release. `gh release create X.Y.Z.BB --target master
  4. Watch CI-full to completion. NEVER cancel it before the tag-and-push
  5. Dispatch CD-sites.
  6. Verify. A "Changed image tag of to X.Y.Z.BB" commit appears in
  7. Post-deploy. Only when PROD rolls to a new MAJOR.MINOR line

What it can do on your machine

Read from SKILL.md and the folder at commit 340d6ee. 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:

    • gh
    • git

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

  • Network

    No URLs in SKILL.md. Its commands use gh and git, 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 no API keys, tokens, secrets or passwords.

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

Context cost

Deploy loads about 1.1k tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 485 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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 485 words (~1,118 tokens).

“Always present the full plan (version, target site, ordered steps) and get the user's explicit confirmation BEFORE tagging, releasing, or deploying anything. The first three version parts are release-engineering decisions a human makes (docs/RELEASING.md); the target site decides who is…”

Deploy has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Deploy use?

About 1.1k tokens (SKILL.md is roughly 4.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
