supply-chain

supply-chain is a skill for Codex from automagik-dev/genie. It costs 52 tokens per session (1,378 once invoked), scanned A, original, MIT.

A security review method for checking how a codebase handles trusted files, dependencies, credentials, incoming data, releases, and CI permissions.

In plain words
What is it for?
Use it to audit trust boundaries, credential handling, injection risks, dependency pinning, release integrity, and the permissions granted to continuous-integration systems.
Why use it?
It helps find places where an attacker controlling an input, dependency, token, or build step could gain unwanted access. It also checks whether software came from a verifiable source.

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 9d 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.

Security & Supply-Chain Review

Runtime syntax: invoke the plugin copy through the active runtime's owner-qualified skill selector; use a bare selector only when intentionally selecting a user-tier copy (a separately installed personal copy; Genie no longer seeds this tier). Cross-skill prose below uses bare names as portable semantic routes; the orchestrator resolves the selector for the active runtime.

Lens

This lane holds that every artifact a system trusts — a release binary, a dependency, a CI token, an inbound message — needs verifiable provenance, and "we downloaded it over HTTPS" is not provenance. Trust boundaries are enumerated, not assumed; the interesting question at each one is "what does an attacker who controls this input get?" Least privilege is the default; every credential and CI permission must justify its scope.

This lane's lens is inspired by the work of Dan Lorenc, creator of Sigstore and founder of Chainguard.

Mandate

Assess and report by default; this is a defensive audit of the user's own repo. Apply hardening only when the invocation explicitly asks. Do not build exploit tooling — demonstrating a finding means citing the code path and describing the impact, not weaponizing it. Findings outside this lane get a one-line handoff to the relevant lane skill under skills/. When the evidence supports a conclusion, state it.

Discover the Ground Truth First

Enumerate before auditing. From the code, CI config, and CLAUDE.md/AGENTS.md, list: every point where external input enters (network listeners, webhook/hook stdin, message queues, downloaded artifacts, CLI args crossing privilege levels), every credential at rest (env vars, key files, tokens) and its handling, the update/release chain (how users get new versions, what verifies them), the CI surface (workflows, triggers, permissions, secrets, third-party actions), and the dependency posture (lockfile, count, where the build runs). Also collect the repo's stated security decisions — fail-closed contracts, documented trust delegations (e.g. "approval authority = membership in channel X"), known accepted risks — the audit judges whether they hold and whether their scope has silently widened, not whether you'd have chosen them.

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 automagik-dev/genie (334 stars, last pushed yesterday), licensed MIT. It adds 52 tokens to every session and 1,378 once invoked, about $0.0003 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.
