Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The automatic postinstall download and execution of a separately released binary presents a real supply-chain risk, even though the archive is checksum-checked. Inspected agent configuration code is tied to explicit CLI installation behavior, and no concrete malicious attack was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-10T01:18:18.985Z - **Finished:** 2026-10-10T01:18:57.388Z - **Download time:** 521 ms - **Static scan time:** 898 ms - **AI review time:** 36983 ms - **Total time:** 38403 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The npm postinstall hook may download and install the package’s companion Skiller binary into the user’s local bin directory. The archive is checked against a checksum fetched from the same release location. - **Trigger:** npm runs the package postinstall hook when installing talking-stick. - **Impact:** This adds and runs a separately downloaded executable during package installation; the inspected code does not establish credential theft or agent control hijacking. - **Evidence paths:** package.json, scripts/postinstall.cjs, scripts/skiller-bootstrap.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-10T01:18:57.388Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook launches a bootstrap script that downloads the release checksum and archive, checks the archive hash, extracts the binary, copies it into the user’s local bin directory, and invokes it to read its version. - **Rationale:** The automatic postinstall download and execution of a separately released binary presents a real supply-chain risk, even though the archive is checksum-checked. Inspected agent configuration code is tied to explicit CLI installation behavior, and no concrete malicious attack was established. - **Files touched:** ~/.local/bin/skiller - **Network endpoints:** https://github.com/mostlydev/skiller/releases/download/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json defines a postinstall hook that runs scripts/postinstall.cjs., The postinstall script launches the Skiller bootstrap during npm installation when the package is installed under node\_modules and its CLI exists., The bootstrap downloads a release archive and checksum from a configurable GitHub release location, then verifies the archive against that downloaded checksum., After verification, the bootstrap installs the binary in the user’s local bin directory and runs it to read its version., The flagged .claude path is part of a harness configuration path resolver; Claude hook installation is exposed through an explicit CLI command. - **Evidence against:** The bootstrap can be disabled through environment variables, and a previously usable Skiller binary skips the download., The inspected setup code does not show credential collection, transmission to an unrelated endpoint, or broad agent configuration mutation. ## Affected versions and remediation This report applies to talking-stick@0.18.2. - Review the evidence and your use of talking-stick@0.18.2 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
