static-webshot-install

name	static-webshot-install
description	Make the static-webshot command available, installing it only if it is missing. Use when another skill reports that `static-webshot` is not on PATH, or when the user asks to install, update or upgrade the ideamans deterministic screenshot CLI. Prefers an already-installed binary, then the latest GitHub release, then a build from source with go install.
license	MIT
compatibility	Requires curl (or wget) and tar to install from a release, or a Go toolchain for the source fallback. Standalone — does not need static-webshot to be present already. Installs from the public repository github.com/ideamans/static-webshot, so no GitHub authentication is needed. The tool additionally needs Chrome or Chromium at run time, which this skill does not install.

static-webshot-install

Make the static-webshot command usable, doing the least work that achieves it.

Route 1 — an existing installation on PATH

command -v static-webshot && static-webshot --version

If that resolves, use it and stop here. Do not check for a newer release — it costs an API call and the user did not ask for an upgrade.

Two checks before trusting the hit:

• It is the right tool. static-webshot llm | head -1 must read # static-webshot — reference for AI agents. If something else owns the name, say so and use an explicit path rather than shadowing theirs.
• It is recent enough. If llm is not a known command, the binary predates the embedded reference — continue to route 2 to upgrade it.

Continue past this section only when the command is missing, is the wrong tool, is too old, or the user explicitly asked to update.

Route 2 — the latest GitHub release

The repository is public, so no authentication is needed.

VERSION=$(curl -fsSL https://api.github.com/repos/ideamans/static-webshot/releases/latest \
  | grep '"tag_name"' | head -1 | cut -d'"' -f4)   # e.g. v0.3.0

Asset names keep the v prefix on the version, and use lowercase OS and arch:

static-webshot_<version-with-v>_<os>_<arch>.tar.gz

<os> is darwin, linux or windows; <arch> is amd64 or arm64, so uname -m reporting x86_64 maps to amd64. Windows ships a .zip. There is no darwin_amd64 build — Intel Macs fall through to route 3.

OS=$(uname -s | tr '[:upper:]' '[:lower:]')             # darwin | linux
ARCH=$(uname -m); [ "$ARCH" = "x86_64" ] && ARCH=amd64  # amd64 | arm64
curl -fsSL -o /tmp/static-webshot.tar.gz \
  "https://github.com/ideamans/static-webshot/releases/download/${VERSION}/static-webshot_${VERSION}_${OS}_${ARCH}.tar.gz"

If the download 404s, list the actual assets on the release page rather than retrying variations.

Install onto PATH

tar -xzf /tmp/static-webshot.tar.gz -C /tmp
mkdir -p ~/.local/bin && mv /tmp/static-webshot ~/.local/bin/ && chmod +x ~/.local/bin/static-webshot

Prefer the first writable directory already on PATH — ~/.local/bin, then /usr/local/bin. Two things not to do on your own initiative:

• If nothing on PATH is writable, leave the binary in /tmp, print the exact sudo mv command and let the user run it. Do not run sudo yourself.
• If ~/.local/bin is not on PATH, give the user the line to add to their shell profile. Do not edit the profile for them.

Route 3 — build from source

Needs a Go toolchain. Note the binary is built from a subdirectory, and go install names the command after that directory, not the module:

go install github.com/ideamans/static-webshot/cmd/staticwebshot@latest

That produces a command called staticwebshot (no hyphen), while the release archive contains static-webshot. If you install this way, tell the user which name they have, or rename it:

mv "$(go env GOPATH)/bin/staticwebshot" ~/.local/bin/static-webshot

Verify

command -v static-webshot && static-webshot --version && static-webshot llm | head -1

Report the version and the path. Then say what is still needed: Chrome or Chromium must be installed for captures to work. This skill does not install a browser. If one is present somewhere unusual, captures can point at it with --chrome-path.
