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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.04708 |
| Opus 5 | $0.00018 | $0.02354 |
| Sonnet 5 | $0.00007 | $0.00942 |
| Haiku 4.5 | $0.00004 | $0.00471 |
Grade B, and why
supply-chain-audit scanned grade B with 2 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 10d 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.
Downloads and executes remote codemediumSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
curl -sSfL https://raw.githubusercontent.com/anchore/syft/main/install.sh | sh -s -- -b /usr/local/bin Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

What this skill does
Performs a comprehensive software supply chain security assessment: inventories all dependencies, runs SCA tooling across detected ecosystems, evaluates SLSA framework compliance (Levels 1–4), generates a CycloneDX/SPDX SBOM, and analyzes exposure across four attack vector categories (dependency, build pipeline, source code, distribution). Outputs a risk findings table, SLSA compliance matrix, and prioritized remediation roadmap.
When to use
- When evaluating supply chain risk before a major release or acquisition
- When responding to a supply chain incident (SolarWinds/XZ-style events)
- When achieving SLSA Level 2+ compliance for a service
- When preparing a software bill of materials for a customer or regulator
- When auditing third-party code integrated into your codebase

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-audit is a skill published in the GitHub repository woohyun212/security-skill (21 stars, last pushed 4mo ago), licensed MIT. It adds 37 tokens to every session and 4,708 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
