supply-chain

supply-chain is a skill for Claude Code, Codex from padamson/playwright-rust. It costs 41 tokens per session (707 once invoked), scanned A, original, Apache-2.0.

A release procedure for checking the safety, licensing, source, and review status of Rust dependencies. It uses cargo audit for known vulnerabilities, cargo deny for dependency policies, and cargo vet for recorded reviews.

In plain words
What is it for?
Use it when changing Rust crates, updating the project version, responding to security advisories, or repairing dependency review records.
Why use it?
It provides a repeatable way to handle dependency updates and security advisories without losing required checks or audit records.

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

supply-chain 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 5d 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.

Supply Chain & Release Hygiene

The project uses three complementary supply-chain tools:

  • cargo audit — vulnerability advisories from RustSec
  • cargo deny — license, duplicate, and source policy
  • cargo vet — explicit audit chain for every dependency

All three run in CI on every push and every dependabot PR. Treat their output as load-bearing — a real cargo audit failure is a security advisory and warrants a patch release; a cargo vet failure usually means an audit chain needs re-stitching after a version change.

When bumping our own version

supply-chain/imports.lock is generated, never hand-edited. The header comment says # cargo-vet imports lock. The [[unpublished.playwright-rs]] entries handle the chicken-and-egg window between bumping Cargo.toml and publishing to crates.io: an entry like version = "0.12.1" audited_as = "0.12.0" tells vet "treat the in-tree version as audited at the prior released version's level."

Proper sequence when bumping Cargo.toml:

  1. Bump version = "X.Y.Z" in workspace Cargo.toml
  2. Run cargo vet regenerate unpublished — automatically removes entries for now-published versions and adds a new [[unpublished]] entry chained to the prior version
  3. If cargo vet still fails (the chain may break when prior versions get published and lose their [[unpublished]] placeholder), bump the [[exemptions.playwright-rs]] version = "..." line in supply-chain/config.toml to the latest published version. The exemption is the anchor that the unpublished entries chain to.
  4. Verify cargo vet, cargo audit, cargo deny check all pass
  5. Commit Cargo.toml, Cargo.lock, supply-chain/imports.lock, and any supply-chain/config.toml exemption bump together

When external dependencies update (dependabot PRs)

Dependabot PRs that bump external crates often surface "missing [safe-to-deploy]" or "missing [safe-to-run]" failures from cargo vet. Resolve by either:

  • Running cargo vet diff <crate> <old> <new> and cargo vet certify to record an explicit audit (preferred for small, reviewable diffs), or
  • Adding an exemption in supply-chain/config.toml (acceptable for well-known crates with negligible delta — match the existing exemption style).

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.

supply-chain is a skill published in the GitHub repository padamson/playwright-rust (141 stars, last pushed 5d ago), licensed Apache-2.0. It adds 41 tokens to every session and 707 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
