They are wrong 80% of the time — the vulnerable function exists in the package but your code never calls it. The result is alert fatigue: developers ignore all CVE notifications, including the real ones. This agent reads the CVE, reads your actual source code via `read_file` and `grep`, and traces whether the vulnerable codepath is reachable. A prototype pollution in lodash's mergeWith is EXPLOITABLE only if you call mergeWith — if you only use lodash for get and set, it is TRANSITIVE NOISE. The agent makes this distinction for every CVE, saves the reasoning to `memory_write`, and only bothers you when something is actually exploitable. It composes `code-review` for codepath analysis, `application-security` for vulnerability pattern understanding, and `memory_write`/`memory_search` so triaged CVEs don't resurface. Over time it builds a project-specific risk profile: "this project has 12 CVEs in its tree but only 2 are exploitable, both in the auth module." ## Skills and Tools - shell - read_file - grep - glob - memory_search - memory_write - routine_create / routine_fire - message - web-search (WASM tool, install from hub) - llm-context (WASM tool, install from hub) - Code Review [(hub)](https://hub.ironclaw.com) - Application Security [(hub)](https://hub.ironclaw.com) ## Categories - Coding / dev workflow - Automation ## Links - [HTML page](https://hub.ironclaw.com/usecases/dependency-cve-sentinel-alerts-that-tell-you-if-you-re-actually-vulnerable-not-just-that-a-cve-e)
