On npm postinstall, the package configures a project-local OpenCode extension and enables two npx-fetched MCP tools. It also performs vendor license verification when a license key is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 94.0% - **Started:** 2026-08-21T18:58:56.168Z - **Finished:** 2026-08-21T18:59:44.254Z - **Download time:** 761 ms - **Static scan time:** 89 ms - **AI review time:** 47235 ms - **Total time:** 48086 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package configures a project-local OpenCode extension and enables two npx-fetched MCP tools. It also performs vendor license verification when a license key is present. - **Trigger:** npm installation of the package - **Impact:** Modifies the target workspace's .opencode control surface; later OpenCode use can run the configured MCP commands. - **Evidence paths:** package.json, scripts/install.js, opencode.tera.example.json - **Review source:** ai\_review - **Reviewed:** 2026-08-21T18:59:44.254Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall project-local agent configuration and license API verification - **Rationale:** This is a guarded but automatic AI-agent extension lifecycle mutation, so it warrants a warning. The inspected source does not establish malware or a broad/foreign control-surface takeover. - **Files touched:** .opencode/agents/\*, .opencode/commands/\*, .opencode/opencode.json, .opencode/opencode.tera.example.json, .opencode/tera-core.manifest.json, .tera/license.state.json, tera-system/\*, tools/\*, project-control/\* - **Network endpoints:** https://teranoo.com/api/license/verify ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** npm postinstall runs the installer automatically., Installer writes agent commands/configuration into the install target's .opencode directory., Installed OpenCode config enables MCP commands through npx., Postinstall sends a supplied license key to the vendor license API. - **Evidence against:** Writes are project-local and ownership-aware; unowned conflicting files are retained., No destructive shell execution, credential harvesting, or remote payload execution was found., The remote request is a bounded license-verification POST to a package-aligned endpoint. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/install.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/install.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 5. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 6. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 7. High: Entrypoint Foreign Package Code Overwrite - **Category:** Source - **Confidence:** 94.0% - **Path:** scripts/install.js - **Public source:** [View source]() Manifest-reachable source overwrites another installed package with package-defined remote behavior. Public source snippet (untrusted): ```javascript Manifest-reachable source resolves another installed package, overwrites its runtime code, and injects package-defined remote behavior. scripts/install.js: function copyFile(src, dest) { fs.copyFileSync(src, dest); fs.copyFileSync(destFile, bak); fs.copyFileSync(srcFile, destFile); copyFile(srcFile, destFile); copyFile(configSrc, configDest); copyFile(configSrc, exampleDest); copyFile(f, d); ``` ### 8. Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** scripts/install.js - **Public source:** [View source]() Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel. Public source snippet (untrusted): ```javascript L10: * - Never overwrites a file it does not own. L11: * - Tracks ownership via `.opencode/tera-core.manifest.json`. L12: * - Only updates files it owns, always keeping a backup first. L13: * - Idempotent: re-running is safe; identical files are skipped. L14: * - Never touches an existing user `opencode.json`. L15: * ... L65: function copyFile(src, dest) { L66: fs.mkdirSync(path.dirname(dest), { recursive: true }); L67: fs.copyFileSync(src, dest); L68: } ... L70: function loadOwnership(target) { L71: const p = path.join(target, ".opencode", MANIFEST_NAME); ``` ### 9. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 10. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 11.

Public source snippet (untrusted): ```text path = tools/tera-fetch.ps1 kind = build_helper sizeBytes = 6816 magicHex = [redacted] ``` ### 12. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 13. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @tera-system/core - **Ecosystem:** npm - **Version:** 0.1.5 - **License:** SEE LICENSE IN LICENSE.md - **Version published:** 2026-08-21T18:54:30.260Z - **Package first seen:** 2026-08-21T18:59:44.254Z - **Package last seen:** 2026-08-28T22:22:07.617Z - **Known versions:** 4 - **Latest version:** 0.2.4 - **Appeal under review:** No - **Description:** Tera System OpenCode Plugin — governance core, 20 agents, 10 commands, distribution tools - **Maintainers:** teranoo - **Keywords:** opencode, plugin, tera, governance, agents, component - **Runtime engines:** node: \>=18 - **Artifact files:** 161 - **Artifact unpacked size:** 1,530,662 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
