A package-installed skill can influence OpenCode agent behavior in the client project. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installation mutates the client project's OpenCode skill directory without an explicit user command. This is a foreign AI-agent control-surface write. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 94.0% - **Started:** 2026-08-17T02:28:40.246Z - **Finished:** 2026-08-17T02:29:22.026Z - **Download time:** 503 ms - **Static scan time:** 58 ms - **AI review time:** 41217 ms - **Total time:** 41780 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation mutates the client project's OpenCode skill directory without an explicit user command. This is a foreign AI-agent control-surface write. - **Trigger:** npm install - **Impact:** A package-installed skill can influence OpenCode agent behavior in the client project. - **Evidence paths:** package.json, skills/postinstall.js, README.md, skills/knowledge-base-management.md - **Review source:** ai\_review - **Reviewed:** 2026-08-17T02:29:22.026Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall installs an AI-agent skill into .opencode/skills - **Attack narrative:** During npm installation, the package runs a postinstall helper that installs its management skill. Its documentation identifies the destination as the client project's .opencode/skills directory, an AI-agent control surface, without requiring a separate user setup command. - **Rationale:** This is a concrete unconsented postinstall mutation of a foreign AI-agent control surface. The absence of exfiltration does not remove that install-time control-surface risk. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. - **Files touched:** skills/postinstall.js, skills/knowledge-base-management.md, .opencode/skills/knowledge-base-\* ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** npm postinstall executes skills/postinstall.js., The lifecycle script delegates skill installation to @andy-toolforge/core., README documents copying a management skill into the client project's .opencode/skills control surface. - **Evidence against:** No network, credential harvesting, or payload download code is present., Runtime storage is a local JSON file; external CLIs run only when kb\_add is invoked. ## 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 skills/postinstall.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 skills/postinstall.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 5. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 6. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 70.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 7. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** skills/postinstall.js - **Public source:** [View source]() The lifecycle script delegates skill installation to @andy-toolforge/core. Public source snippet (untrusted): ```javascript const { installSkills } = require('@andy-toolforge/core'); installSkills({ domain: 'knowledge-base', sourceDir: __dirname }); ``` ### 8. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** README.md - **Public source:** [View source]() README documents copying a management skill into the client project's .opencode/skills control surface. Public source snippet (untrusted): ```markdown The postinstall copies `skills/knowledge-base-management.md` into the client project's `.opencode/skills/` (prefixed `knowledge-base-`). ``` ## 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:** @andy-toolforge/knowledge-base - **Ecosystem:** npm - **Version:** 0.1.1 - **License:** MIT - **Version published:** 2026-08-17T02:18:06.521Z - **Package first seen:** 2026-08-17T02:29:22.026Z - **Package last seen:** 2026-08-17T02:29:22.026Z - **Known versions:** 1 - **Latest version:** 0.1.1 - **Appeal under review:** No - **Description:** Filesystem-first knowledge base facade for AI agents: JSON store with CRUD/search, optional best-effort Supermemory/Serena adapters, and a management skill installed into client projects. - **Keywords:** knowledge, memory, knowledge-base, facade, supermemory, serena, persistence - **Artifact files:** 6 - **Artifact unpacked size:** 18,995 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
