aurora-setup

aurora-setup is a skill for Claude Code from AURORA-NEURO/aurora-agent. It costs 79 tokens per session (660 once invoked), scanned A, original, Apache-2.0.

A setup and troubleshooting guide for the AURORA Agent backend, an MCP server written in Rust that provides tools over a local text connection. It explains where the source checkout can be found, how to build it, and how to diagnose startup problems.

In plain words
What is it for?
Use it to install, build, configure, or troubleshoot the aurora-agent backend and its bioprism-mcp server. It includes commands for an offline Rust build and guidance for Windows errors.
Why use it?
It removes guesswork when the backend will not start or its tools are missing. It also documents the required environment variable and a Windows execution issue.

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

aurora-setup 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 7d 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AURORA backend setup

The aurora-agent plugin launches bioprism-mcp, the MCP server of the AURORA Agent workspace (264 tools; JSON-RPC 2.0 over newline-delimited stdio; stdout is JSON-RPC only, diagnostics go to stderr).

Where the backend lives

The plugin's launcher (scripts/aurora-mcp.mjs) resolves the checkout in this order and refuses with a precise stderr message if nothing matches:

  1. AURORA_AGENT_ROOT environment variable
  2. ~/aurora-agent
  3. ~/bioprism

A directory qualifies when it contains Cargo.toml. Set AURORA_AGENT_ROOT when the checkout lives anywhere else.

Build

git clone https://github.com/AURORA-NEURO/aurora-agent
cd aurora-agent
cargo build --release --offline -p bioprism-mcp

The workspace builds offline against pinned versions (.cargo/config.toml sets net.offline = true); you cannot add external crates. A release build of the full three-binary set is -p bioprism-cli -p bioprism-mcp -p bioprism-api and takes a long time (codegen-units = 1, thin LTO) — the MCP server alone is faster.

Windows gotcha: os error 4551

If a freshly linked binary reports os error 4551 ("never executed"), Windows Application Control blocked it — the program NEVER RAN, even though cargo reports a failure. Touch a source file to force a relink and rebuild. In test suites this silently truncates --workspace totals; a suite that never ran looks like a suite that failed.

What --root means

The launcher passes --root <checkout>. Root is a confinement boundary: every path a tool receives resolves inside it — absolute paths, .. traversal, and symlink escapes are refused. The reference fixtures (fixtures/fiber-v0.1/radiogenomic_world.json, fixtures/fiber-v0.1/leakage_query.json) live inside root, so tool calls can name them by that relative path.

Known caveat: the conformance_run tool bakes a build-machine fixtures path at compile time; it only works when the checkout has not moved since it was built.

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.
