What is AppBuilderSdk CLAUDE.md?

A project instruction file for AppBuilderSdk, a software project with a main Git repository and a separately checked-out shared-code repository.

Use it when changing AppBuilderSdk code, shared code, worktrees, Git history, dependencies, or local viewer development.

It prevents common repository mistakes, such as committing the wrong files, using the wrong branch or ticket format, and writing files with incorrect line endings.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00777	$0.00777
Opus 5.5	$0.00311	$0.00311

Security

Grade A, and why

AppBuilderSdk CLAUDE.md 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 today.

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 — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AppBuilderSdk

Repositories

Two git repos: the root (AppBuilderSdk, usually on development) and src/shared, a separate clone of AppBuilderShared. Run shared git commands as git -C src/shared .... The root commits only the shared pointer (<KEY>: shared update) plus app, tests and public/, after src/shared is committed.
Shared code also runs in AppBuilderIJewel3D. src/shared/CLAUDE.md loads its host rules when you work there.
New worktree: a SessionStart hook inits src/shared and writes .vscode/settings.json. Check out task/<KEY> in both repos.
viewer.local.ts can link ../Viewer. Viewer bugs are fixed there and need a dev server restart. Run pnpm install when the installed viewer version differs from package.json.

Git

Branch task/<KEY>. Every commit message starts with the ticket (SS-10004: ...).
git checkout -- <file> restores from the index. Use git checkout HEAD -- <file> when the file is staged.

Line endings

The working tree is CRLF, git stores LF (autocrlf), and eslint enforces linebreak-style: CRLF. Edit with the Edit/Write tools. sed -i and plain Python writes produce LF and hundreds of lint errors, and Prettier (endOfLine: auto) does not repair them. In Python, write with newline='' and \r\n.

Checks (changed files only)

Format: npx prettier --write <files> (also organizes imports). Some untouched tests already fail prettier --check; ignore those.
Lint: npx eslint <files>
Typecheck: npx tsc --noEmit -p . at the root (covers src/shared). Always run it after changing forwardRef type parameters or host elements (svg vs img), or spreading a ref onto a third-party component. Don't spread a union-typed ref onto a component that accepts one host type; narrow the ref at each host.
Unit test: npx jest --config jest.config.mjs <path>. Tests live in __tests__ next to the module; store tests need the jsdom environment header.
jest.mock replaces all exports. When you add a named export, find the suites that jest.mock that module, keep the real exports with ...jest.requireActual(...), and run those suites too (or pnpm test, which CI runs).
E2E: e2e-testing skill. Never the whole suite. Don't deploy or rerun e2e unless asked or /implement or /spec runs it.

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.
