bxc-build

bxc-build is a skill for Claude Code from aphrody-code/bxc. It costs 32 tokens per session (176 once invoked), scanned A, original, Apache-2.0.

A build workflow for producing bxc Rust bridges, Bun standalone programs, and native MCP server executables. It covers requested targets, release builds, artifact paths, and basic startup checks.

In plain words
What is it for?
Use it for Windows builds, full releases, cross-platform artifacts, and smoke tests of the generated MCP executable.
Why use it?
It gives a consistent way to turn the project into distributable files and catch version or MCP startup problems after building.

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

bxc-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 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.

What it actually says

Build only the requested targets. Typical commands are:

bun run build:win
bun run build:mcp:win

For a full release, use the repository's bun run build workflow and verify the generated artifacts under dist/standalone/. On Windows, the MCP executable is dist/standalone/bxc-mcp-windows-x64.exe; the global MCP command is bxc-mcp.

Keep Rust and Bun versions aligned with the repository manifests. Report the exact artifact paths and run a version or MCP initialize smoke test after a successful build.

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.
