xberg-developer

xberg-developer is an agent for Claude Code from jamon8888/hacienda-private. It costs 15 tokens per session (228 once invoked), scanned A, original, MIT.

An agent that provides general development guidance for xberg, a Rust document-processing project with wrappers for languages such as Python and TypeScript. It treats the Rust core as the main implementation and the language bindings as thin adapters.

In plain words
What is it for?
Use it for xberg changes that affect the Rust core, language bindings, FFI (foreign-function interfaces), ONNX features, WebAssembly builds, or test coverage.
Why use it?
It helps keep business logic in one place and follows the project's build, safety, testing, versioning, and platform rules.

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

xberg-developer 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 1mo 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.

What it actually says

When working on xberg:

  1. Rust core is the single source of truth — all business logic in crates/xberg/src/
  2. Bindings (Python, TypeScript, Ruby, PHP, etc.) are thin wrappers — never duplicate core logic
  3. Use task commands for all operations: task build is core-only; use task build:bindings or task build:all explicitly when bindings are needed
  4. Build FFI layer first if needed: task build:bindings
  5. For ONNX features: ensure ORT_LIB_LOCATION is set or use download-binaries feature
  6. All unsafe blocks require SAFETY comments. No .unwrap() in production code.
  7. Coverage targets: 95% for Rust core, 80% for bindings
  8. WASM builds are sync-only — implement SyncExtractor for WASM-compatible extractors
  9. Version in root Cargo.toml is the single source of truth for all binding packages
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.
