name: deepsec description: Use deepsec (an AI-powered vulnerability scanner) — running scans, configuring projects, writing matchers, and authoring plugins. Activates when the user asks how to scan, configure, or extend deepsec in a project that has deepsec installed.

deepsec

deepsec is an AI-powered vulnerability scanner. This skill activates when deepsec ships inside node_modules/ — typically because the user ran npx deepsec … (which caches the package locally). In the more common dedicated-git setup the user works inside a clone of vercel-labs/deepsec and the same docs sit at docs/ from the repo root — read those instead when this skill fires from outside a node_modules.

When the user asks how to use, configure, or extend deepsec, read the relevant doc before answering — the docs are the source of truth, not your training data.

Where the docs are

node_modules/deepsec/dist/docs/ (or <deepsec-clone>/docs/):

• getting-started.md — first-scan walkthrough
• configuration.md — full deepsec.config.ts reference
• plugins.md — plugin slots (matchers, notifiers, ownership, people, executor)
• writing-matchers.md — how to grow the matcher set with a coding agent
• models.md — model selection, defaults, refusals, future models
• vercel-setup.md — getting AI Gateway and Vercel Sandbox keys / tokens
• architecture.md — pipeline internals
• data-layout.md — data/ schemas (FileRecord, RunMeta, …)
• faq.md — cost, model choice, sandbox mode, FP rate

Worked example

node_modules/deepsec/dist/samples/webapp/ (or <deepsec-clone>/samples/webapp/) is a complete reference setup — deepsec.config.ts with an inline plugin, two custom matchers under matchers/, an INFO.md for AI prompt context, and a per-project config.json. When the user asks "what should my config look like?", read this directory.

How to answer common questions

• "How do I run a scan?" → getting-started.md.
• "What goes in deepsec.config.ts?" → configuration.md + samples/webapp/deepsec.config.ts.
• "How do I add a matcher?" → writing-matchers.md + samples/webapp/matchers/*.ts.
• "How do I write a plugin?" → plugins.md + samples/webapp/deepsec.config.ts (inline plugin pattern).
• "What does deepsec actually do?" → architecture.md.
• "What's in data/<id>/files/foo.json?" → data-layout.md.
• "Which model / agent should I use?" → models.md.
• "How do I get an AI Gateway / Sandbox token?" → vercel-setup.md.

Read the doc before paraphrasing. The CLI flag set, defaults, and plugin-contract field names change — quote the doc, don't recall.
