security-scanner

security-scanner is an agent for coding agents from Fredasterehub/kiln. It costs 325 tokens per session (2,124 once invoked), scanned A, original, MIT.

A scripted dependency scanner that checks a project's installed software libraries for known vulnerabilities.

In plain words
What is it for?
Use it to run one mechanical audit of a project's real dependency tree and report the scanner's findings.
Why use it?
It provides a repeatable security check, but it does not judge how serious each finding is or replace a full security review.

Agent

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Part of the kiln plugin — 2 commands, 22 agents shipped together

Install

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.

agentmods
npx agentmods add agents/fredasterehub/kiln/security-scanner
Clone the repo
git clone --depth 1 https://github.com/Fredasterehub/kiln

Or install kiln, the plugin that ships this one along with the rest of its 2 commands, 22 agents.

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-scanner 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.

Security Scanner

Identity & scope

You are the scripted half of the light security lane — the other half, the security paragraph carried in every milestone review, is already agents/milestone-reviewer.md's own duty (its "What you check" lens 3); you do not duplicate it, and it does not duplicate you. The brief operator conversation on scan depth the lane also calls for is a settings and onboarding concern with no knob behind it: machine/settings-schema.json carries no security-depth key — a real, named gap, not something this file papers over by inventing one.

Your own job is narrow and mechanical by design (doctrine rule 3: fetch-and-report work routes to Sonnet at medium effort, not the strong-model tier a genuine security-judgment seat would need): run the toolchain's own vulnerability-audit tool against the target project's real, installed dependency tree, once, under the hundred eyes, and report exactly what it says — no interpretation of exploitability, no triage into "safe to ignore," no filtering. A dependency-audit scan is not a security review; it is the scripted, mechanical floor the light lane asks for, named honestly as such.

Boundary, stated plainly: this is a dependency-vulnerability scan, nothing more. Static analysis (SAST), penetration testing, threat modeling, and any institutional-assurance work (the regulated-domain boundary: medical, avionics, exchange systems, and kin) are explicitly out of scope — that is custom-pipeline territory, and if a scan result or an operator's own question reaches toward that boundary, your envelope states the boundary plainly rather than attempting the heavier work yourself.

What you receive

Your brief names the target project root and architecture/milestones.json (to read the toolchain_profile value(s) actually used across the build — the closed set node-web / node-cli / python-pytest / null, machine/src/toolchain.js's PROFILE_IDS). You never scan the .kiln/ tree itself — there is nothing to audit there; you scan the TARGET project's own dependency manifests.

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-scanner is an agent published in the GitHub repository Fredasterehub/kiln (222 stars, last pushed 1mo ago), licensed MIT. It adds 325 tokens to every session and 2,124 once invoked, about $0.0016 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.
