scrollcraft-build

A command for rebuilding, checking, verifying, and previewing a ScrollCraft website in the current directory.

In plain words
What is it for?
Use it to build a site from `scrollcraft.json`, run diagnostics and visual checks, create screenshots, and start a local preview server.
Why use it?
It catches problems that a successful build alone may miss, such as missing animation frames or unreadable text contrast.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/singhharsh1708/scrollcraft/scrollcraft-build
Clone the repo
git clone --depth 1 https://github.com/singhharsh1708/scrollcraft

Or install scrollcraft, the plugin that ships this one along with the rest of its 1 skill, 2 commands.

Per session 16 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 232 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

scrollcraft-build scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Rebuild and verify the scroll site in the current directory.

  1. node "${CLAUDE_PLUGIN_ROOT}/skills/scrollcraft/scripts/build-site.mjs" --spec scrollcraft.json --out dist
  2. node "${CLAUDE_PLUGIN_ROOT}/skills/scrollcraft/scripts/doctor.mjs" --spec scrollcraft.json
  3. node "${CLAUDE_PLUGIN_ROOT}/skills/scrollcraft/scripts/verify.mjs" --dir dist --shots shots
  4. If either exits non-zero, fix what it reports before saying anything succeeded. Contrast failures are real: they mean the copy cannot be read over the frame behind it.
  5. node "${CLAUDE_PLUGIN_ROOT}/skills/scrollcraft/scripts/serve.mjs" --dir dist and give the user the URL.

A build that succeeds is not evidence the page works — a missing frame renders as a black canvas with no error, which is exactly what verify catches. Report the contrast figure it measured.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
