Runtime is pure Web Standard APIs (fetch, Request, Response, Uint8Array,
CompressionStream, crypto.subtle, btoa) — zero runtime dependencies.
Core (src/core/, runs identically on Node 18+ and Workers):
- atlas.ts auto-generated 9x15 JBM glyph atlas, base64-inlined (17KB)
- png.ts minimal grayscale PNG encoder via CompressionStream
- render.ts text → packed PNG, soft-wraps at 100 cols, ≤1568px tall
- transform.ts request body rewriter (system + tool docs → image blocks)
- proxy.ts fetch-handler that transforms then forwards to Anthropic
- types.ts Anthropic Messages API types we touch
Adapters:
- src/node.ts node:http server + CLI flag parsing
- src/worker.ts export default { fetch } for wrangler dev/deploy
Build tooling:
- scripts/gen-atlas.ts @napi-rs/canvas → atlas.ts (build-time only)
- scripts/build.mjs esbuild Node bundle; wrangler handles Worker
- tsconfig.json strict, ES2022, Workers types
Tests (vitest): 8 passing — PNG signature, base64 round-trip, single +
multi-image renders, transform no-op + compress paths, billing-line strip,
tool fold + stub.
E2E smoke: 16K char system → 2 PNGs (36KB) → mock upstream, 34ms.
Next: replace docs, then verify byte-output parity against legacy/python.
