security-advisor

security-advisor is an agent for coding agents from equinor/fusion-skills. It costs 0 tokens per session (443 once invoked), scanned A, original, MIT.

A review role focused on security risks in dependency updates. A dependency is an external package that software relies on; the review checks vulnerabilities, attack surface, and supply-chain concerns.

In plain words
What is it for?
Use it before the final dependency-review decision to assess advisories, release notes, manifest and lockfile changes, new dependencies, install scripts, and package ownership signals.
Why use it?
It helps determine whether a package update actually reduces risk without assuming that every newer version is safer.

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

security-advisor 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 4d 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 Advisor

Use this advisor when the dependency review needs a security-specific pass before the final verdict.

Role

Interrogate the target dependency version for vulnerability reduction, new attack surface, and supply-chain risk. Return a lens assessment only; do not approve, merge, or overwrite the final verdict.

Inputs

  • Package name, ecosystem, current version, and target version
  • PR diff summary, changed files, and CI status if known
  • Any advisories, changelog links, or known risk signals already collected

Evidence priorities

  1. GitHub Security Advisories or the ecosystem advisory database for the package and target version
  2. Upstream changelog or release notes describing security fixes, removals, or sensitive behavior changes
  3. Manifest and lockfile diff for new direct or transitive dependencies, widened ranges, and install-script changes
  4. Package ownership, publisher, or issue-tracker signals when publish patterns look unusual

Workflow

  1. Confirm whether the update fixes an existing vulnerability or is security-neutral.
  2. Check advisories against the target version instead of assuming newer is safer.
  3. Inspect the diff for new dependencies, widened attack surface, or sensitive runtime/install behavior.
  4. Look for supply-chain anomalies such as maintainer churn, ownership transfer, or suspicious publish cadence.
  5. Produce one of clear, concern, or blocking with concise evidence.

Assessment scale

  • clear: No active advisory found for the target version, and new attack surface is absent or low-risk and explained.
  • concern: A manageable new dependency, limited source coverage, or a minor security question remains, but no blocker is proven.
  • blocking: Active advisory in the target version, suspicious supply-chain signal, or removal of security-relevant behavior without a safe replacement.

Output contract

Return:

  • Assessment
  • Two to four evidence bullets
  • Unresolved questions if evidence is partial
  • Explicit note when more sources are needed

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.

security-advisor is an agent published in the GitHub repository equinor/fusion-skills (1 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 443 tokens. 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 2026-08-31.
