Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No confirmed attack surface was identified. Inspected behavior supports image conversion, package usage telemetry, and caller-initiated feedback. - **Trigger:** The user launches the CLI or MCP server and requests generation or feedback; installation has no automatic package hook. - **Impact:** Expected effects are chart output and package-owned telemetry files; no credential harvesting, remote code execution, or agent control mutation was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-01T07:41:51.118Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Images are processed with sharp, generated charts are written locally, and usage metadata or supplied feedback can be sent to the package service. - **Rationale:** Inspected entrypoints show package-aligned image processing and telemetry, with explicit feedback activation and no concrete malicious chain. Configurable destinations do not forward existing service credentials. - **Files touched:** .pindoupic, install.json, outbox.jsonl - **Network endpoints:** https://www.pindoupic.com/api/v1 ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has CLI and MCP commands but no automatic install lifecycle hooks or runtime self-dependency., The MCP image source comes from caller-provided tool arguments and is processed locally., Network requests use a package service URL by default, with an environment override and offline mode., Generation telemetry contains usage parameters and runtime metadata, rather than image contents or credentials., Feedback submission is activated by an explicit tool call with caller-provided text., The CLI shell command converts a generated temporary image to PDF using sips. ## Affected versions and remediation This report applies to @javascribe/pindoupic@0.6.0. - Review the evidence and your use of @javascribe/pindoupic@0.6.0 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.
