Installing runs a same-vendor CLI shim/global-install fallback. Loading the plugin mutates OpenCode provider configuration, installs a provider skill, and starts a localhost payment proxy. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-09T16:47:07.918Z - **Finished:** 2026-08-09T16:47:45.672Z - **Download time:** 501 ms - **Static scan time:** 370 ms - **AI review time:** 36882 ms - **Total time:** 37754 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing runs a same-vendor CLI shim/global-install fallback. Loading the plugin mutates OpenCode provider configuration, installs a provider skill, and starts a localhost payment proxy. - **Trigger:** npm postinstall; later OpenCode plugin load and Paytaca AI requests. - **Impact:** Modifies user-level CLI and OpenCode state; routes provider requests and wallet-hash metadata through Paytaca infrastructure. - **Evidence paths:** package.json, scripts/postinstall.js, dist/index.js, dist/proxy.js, dist/bundled/proxy.js, dist/bundled/wrapper.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T16:47:45.672Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic CLI, OpenCode extension, and local payment-proxy setup. - **Rationale:** Source inspection confirms non-consensual lifecycle and runtime agent-environment mutation, including a global-install fallback, so it should be warned. The behavior is aligned with the package’s stated Paytaca OpenCode/payment function and no concrete malicious chain was identified. - **Files touched:** ~/.npm-global/bin/paytaca, ~/.opencode-paytaca/config.json, ~/.opencode-paytaca/proxy.js, ~/.opencode-paytaca/paytaca-pay-wrapper.mjs, ~/.opencode-paytaca/proxy.pid, ~/.opencode-paytaca/proxy.log, ~/.local/share/opencode/auth.json, ~/.config/opencode/skills/paytaca-wallet/SKILL.md - **Network endpoints:** https://api.paytaca.ai, http://localhost:8001 ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall., scripts/postinstall.js replaces/creates global paytaca symlink and falls back to npm install -g paytaca-cli., dist/index.js modifies OpenCode auth.json and copies a global paytaca-wallet SKILL.md on plugin load., dist/proxy.js writes and launches a detached local proxy. - **Evidence against:** All observed network forwarding is for the declared Paytaca AI provider., Proxy binds localhost and forwards configured model requests to the documented backend., No credential-file harvesting or unrelated exfiltration found., Payment wrapper requires confirmed payment before sending BCH. ## Public findings ### 1.
