It also automatically synchronizes existing agent skill installations. - **Trigger:** npm postinstall under node\_modules/talking-stick - **Impact:** Arbitrary code from the mutable release source can execute with the installing user's privileges. - **Evidence paths:** package.json, scripts/postinstall.cjs, scripts/skiller-bootstrap.cjs, scripts/postinstall-sync.mjs, dist/skill-install.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T07:58:14.973Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary bootstrap and execution during postinstall - **Attack narrative:** Installing the package runs postinstall, which invokes a bootstrapper. When no usable skiller binary exists, it downloads a release archive and its checksum from the same GitHub release path, installs the extracted executable under the user's home directory, and runs it. This is unconsented install-time remote payload execution; the checksum does not provide an independently pinned trust boundary. - **Rationale:** The package executes a remotely fetched binary during postinstall, with release selection and checksum material both controlled by the same external source. This establishes a concrete install-time remote-code-execution chain. - **Files touched:** scripts/postinstall.cjs, scripts/skiller-bootstrap.cjs, scripts/postinstall-sync.mjs, $HOME/.local/bin/skiller, $HOME/.agents/skills/talking-stick - **Network endpoints:** github.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall invokes the skiller bootstrap when installed under node\_modules., Bootstrap downloads a release archive, installs it in ~/.local/bin, then executes it for version verification., The checksum is downloaded from the same mutable release location as the archive, not pinned in-package., postinstall also runs automatic AI-agent skill synchronization. - **Evidence against:** Bootstrap can be disabled through environment variables., Skill sync skips missing targets and preserves customized content., No credential harvesting or data-exfiltration code was found in inspected sources. ## Public findings ### 1.
