rust-workspace

rust-workspace is a skill for Claude Code, Codex from KalarisLabs/Skill-Doctor. It costs 39 tokens per session (421 once invoked), scanned A, original, Apache-2.0.

Rules for organizing a Rust Cargo workspace, which is one repository containing multiple related Rust packages called crates. It defines crate boundaries, dependency rules, and allowed default features.

In plain words
What is it for?
Use it when creating crates, moving modules, editing Cargo.toml, adding dependencies, or changing workspace structure.
Why use it?
It prevents modules from taking on the wrong responsibilities and keeps dependencies, builds, and optional features under control.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

rust-workspace 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

Rust workspace

Boundaries

  • skill-doctor: binary only. clap + report printers. No YARA, no taint, no MCP protocol.
  • skill-doctor-core: engines + scoring. No clap. No tokio.
  • skill-doctor-rules: build.rs embeds compiled YARA. Scan path never compiles rules.
  • skill-doctor-neutralize: pure functions. No filesystem, no network.
  • skill-doctor-mcp: tokio allowed. Depends on core + neutralize.
  • skill-doctor-sandbox: feature-gated. Only unsafe crate.

Dependency rules

  1. Versions live in root [workspace.dependencies]. Member crates use { workspace = true }.
  2. Adding a crate requires updating DEPENDENCIES.md in the same change.
  3. anyhow only in the binary. Libraries use thiserror.
  4. Default features of skill-doctor must not enable sandbox, tui, or network.
  5. After any Cargo.toml edit: cargo metadata --locked (or generate lockfile once) must succeed.
  6. Forbidden on the default path: Python/PyO3, Node, OpenAI/Anthropic SDKs, scan-time YARA compile.

Module layout inside core

src/l0/  intake, digest, cache
src/l1/  pattern, taint, entropy, unicode, capability
src/l4/  intel (feature)
src/l5/  merge, coverage, report types
src/taxonomy.rs   SD-01…SD-11 only unless the whitepaper adds a class

Do not collapse crates to “make it simpler.” The boundaries exist so L1 stays a library other tools can embed.

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.
