The checksum is fetched from the same mutable release source, so it does not establish an independent trust boundary. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-13T19:00:58.170Z - **Finished:** 2026-08-13T19:01:43.376Z - **Download time:** 260 ms - **Static scan time:** 955 ms - **AI review time:** 43990 ms - **Total time:** 45206 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall fetches, extracts, installs, and executes an external skiller binary when one is absent. The checksum is fetched from the same mutable release source, so it does not establish an independent trust boundary. - **Trigger:** npm install of talking-stick when no usable skiller binary is found - **Impact:** A compromised or redirected release source can yield code execution as the installing user. - **Evidence paths:** package.json, scripts/postinstall.cjs, scripts/skiller-bootstrap.cjs, scripts/postinstall-sync.mjs, dist/skill-install.js, dist/instructions.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T19:01:43.376Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time remote binary bootstrap and execution - **Rationale:** The package contains a concrete install-time remote binary execution chain, but the inspected source does not show malicious intent, theft, or destructive behavior. Warn rather than block under the stated policy. - **Files touched:** scripts/postinstall.cjs, scripts/skiller-bootstrap.cjs, scripts/postinstall-sync.mjs, ~/.local/bin/skiller - **Network endpoints:** github.com, https://github.com/${SKILLER\_REPO}/releases/download/${SKILLER\_VERSION} ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for:** postinstall invokes the skiller bootstrap., Bootstrap downloads a release archive from GitHub., The downloaded archive is verified only against a co-downloaded checksum, then copied to ~/.local/bin., Bootstrap executes candidate skiller binaries to obtain their version., Postinstall also syncs already-installed agent skills and instructions. - **Evidence against:** No credential harvesting or data-exfiltration code found., No obfuscated payload, eval, or dynamic code-loading path found., Agent hook/skill changes are guarded by existing config/installed-skill checks or explicit tt install commands. ## Public findings ### 1.
