Professional .claude/ template + compression proxy · Claude Code
Bootstrap Pro is the .claude/ baseline that structures serious projects: Spec-Driven Development, VSA + DDD, ADRs, hooks and verification loops. Ultron Mode is ultronpx, the local proxy that converts dense context blocks into PNG — up to ~3× cheaper per converted block, with exact identifiers protected and fail-open guaranteed. One bundle, one license.
Bootstrap Pro structures the project before the first line of code; Ultron Mode cuts the cost of every request after it. You skip the first two days of setup — and pay less for every day that follows.
The .claude/ baseline for serious projects: Spec-Driven Development, Vertical Slice + DDD, API-First, ADRs, Diátaxis docs, DevSecOps, ready-made subagents, skills and hooks — with a NOTES.md living memory and cross-session continuity. Delivered as a watermarked zip + GitHub template repository.
A local proxy that converts dense context blocks into PNG — vision tokens are priced per pixel, not per text: up to ~3× cheaper per block, ~45% measured savings per imaged block on real traffic. Verbatim Guard, adaptive gate, fail-open and auditable savings. A rewrite of the pxpipe concept, by teamchong, with attribution.
The Bootstrap disciplines your context — specs, NOTES.md, waves and compact hooks keep sessions lean and resumable. The ultronpx compresses whatever dense content remains: tool results, logs, history. Structure reduces waste; compression reduces the price of what's unavoidable.
It's the same .claude/ baseline used to start every serious B2Tech project — each capability below ships ready, with the assets named.

Every piece below exists for that — all shipped in the ultronpx 2.x that comes with the bundle.

All on 127.0.0.1.
The ultronpx sits between Claude Code and Anthropic — a position that demands explicit guarantees, not promises.
The API key is never written down
The key lives only in the client environment. The proxy forwards the header to api.anthropic.com and never writes it to config, logs, telemetry events or pixels.
Secrets pin the block as text
If the Verbatim Guard detects a secret in a block, the whole block is kept out of the render — credentials never become an image, not even by accident.
Byte-exact identifiers
SHAs, UUIDs, IPs and stack traces go to a textual sidecar before rendering. Claude cites the exact commit — not an approximate visual reading of it.
Fail-open, always
Any internal error degrades to a byte-identical passthrough. The proxy never blocks your flow or corrupts a payload — the worst case is the behavior without ultronpx.
Local-first, zero analytics
Listens on 127.0.0.1:47821; the only network destination is api.anthropic.com — the same as Claude Code without the proxy. No telemetry byte leaves your machine.
Auditable end to end
Every modified request leaves a trail in ~/.ultronpx/events.jsonl — what was converted, what it cost, what it would have cost. The license is validated at activation; after that, zero contact with B2Tech servers.
Delivery is automatic after checkout. The template arrives by email and GitHub; ultronpx activates with your purchase email. Requires Node.js ≥ 22.
Two delivery channels — the zip is the official licensed copy; the repository is the git-native convenience.

Five commands and one environment variable. From then on, use Claude Code as usual and watch the savings.
