This is a user-invoked but opaque agent-extension lifecycle surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 86.0% - **Started:** 2026-08-06T00:31:47.958Z - **Finished:** 2026-08-06T00:32:33.681Z - **Download time:** 756 ms - **Static scan time:** 177 ms - **AI review time:** 44789 ms - **Total time:** 45723 ms ## Security analysis ### Published attack-surface review - **Summary:** The obfuscated CLI can inspect a Claude installation, prompt for persistence, supervise its core process, and update its companion core globally. This is a user-invoked but opaque agent-extension lifecycle surface. - **Trigger:** Running the \`whalent\` CLI. - **Impact:** Could persist or alter the package-owned agent runtime; obscured source prevents validating the exact target and scope. - **Evidence paths:** package.json, scripts/preinstall-check.cjs, dist/index.cjs, dist/core.cjs - **Review source:** ai\_review - **Reviewed:** 2026-08-06T00:32:33.681Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated Claude-aware persistence and self-updating core wrapper. - **Rationale:** No concrete malicious install-time chain was verified, but the obfuscated Claude-aware persistence and self-update behavior is a material unresolved agent-extension risk. - **Files touched:** scripts/preinstall-check.cjs, dist/index.cjs, dist/core.cjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** \`dist/index.cjs\` and 14 MB \`dist/core.cjs\` are deliberately obfuscated., The CLI detects and classifies installed \`@anthropic-ai/claude-code\` shims., \`ensurePersistencePrompt()\` runs on normal CLI invocation before the core starts., Runtime code supervises/restarts the core and can run \`npm -g\` to change its core version., The install hook executes \`scripts/preinstall-check.cjs\`. - **Evidence against:** \`scripts/preinstall-check.cjs\` only rejects Node versions below 20., No postinstall hook or confirmed install-time agent-control mutation was found., The observed persistence path is reached from explicit CLI execution, not package installation., No concrete credential exfiltration endpoint was established. ## Public findings ### 1.
