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

appbuilder-sdk 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Working in AppBuilderSdk / AppBuilderShared

Workflow only. Do not add feature behavior, ticket notes, or API semantics to this file. Put those in a requestable topic rule (see Agent rules).

Repository layout

  • Two git repos. Root AppBuilderSdk (usually development) contains src/shared, a separate clone of AppBuilderShared. Shared changes: git -C src/shared .... Root only records the shared pointer ("shared update") plus app, tests, and public/.
  • New worktrees: follow .cursor/rules/worktree-shared-repo.mdc.
  • Path alias: @AppBuilderLib/... → src/shared/.... FSD: entities/ (parameter, session, viewport), features/, widgets/, shared/. Tests live in __tests__ next to the module (jsdom env header for store tests).
  • Viewer: @shapediver/viewer.*. viewer.local.ts can link ../Viewer; viewer bugs are fixed there and need a dev server restart. Keep node_modules in sync (pnpm install) when versions differ.

Git and commits

  • Branch names: task/JIRA-ISSUE-ID. Every commit message starts with the ticket (SS-10004: ...).
  • Commits are SSH-signed via 1Password; signing fails from an agent shell. Stage and describe; let the user commit.
  • git checkout -- <file> restores from the index; use git checkout HEAD -- when files are staged.

Line endings and edits

  • Working tree is CRLF, git stores LF (autocrlf). eslint linebreak-style: CRLF.
  • Never sed -i or plain Python writes on source; they produce LF and hundreds of lint errors. Use the Edit tool, or Python with newline='' and \r\n.

Checks (judge only files you changed)

npx prettier --check <files>
npx eslint <files>
npx tsc --noEmit -p .          # root, covers shared
npx jest --config jest.config.mjs src/shared/<path>

Some untouched tests have pre-existing prettier violations.

  • Typecheck: IDE ReadLints / ESLint are not a substitute for root tsc. After changing forwardRef type parameters, host elements (svg vs img, etc.), or spreading a ref onto a third-party component, run npx tsc --noEmit -p .. Do not put a union-typed ref into a props object that is spread onto a component that only accepts one host type — narrow the ref at each host instead.
  • Mocks: jest.mock replaces all exports. When adding a named export that other modules import, search for jest.mock of that module and keep named exports via ...jest.requireActual(...) (override only what the test needs). A passing targeted test is not enough if other suites mock the changed module; run those tests, or pnpm test (what CI runs).

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.
