Scanner verdict

Verdict: suspicious
Confidence: medium
Model: gpt-5-mini
Summary: The skill mostly matches its stated purpose (a pre‑install security gate) but has several coherence and privacy concerns — notably a bundled API key, instructions to auto‑upload code to an external registry, and instructions promoting automatic checks without explicit user consent.
Guidance: This skill is plausibly what it claims (a pre-install audit/gate) but there are several red flags you should address before installing or enabling it automatically: - Do not run the installer curl|bash blindly. Instead clone the repo and inspect scripts/register.sh, scripts/upload.sh, and scripts/gate.* for network calls and what data they send. - The repo includes config/credentials.json with an api_key. Treat that as a secret baked into the package — it should be removed and replaced with a user-provided key. Do not use the included api_key; rotate it if you control that account. - The SKILL.md instructs agents to run checks and upload reports without asking the user. If you care about privacy or provenance, require explicit user consent before any upload, and prefer a local-only mode that does not send source code to the registry. - Run the skill in a sandbox (container or VM) first to observe behavior, and test gate.sh/check.mjs locally with harmless packages. - If you plan to allow the skill to run autonomously, configure it with your own AGENTAUDIT_API_KEY (not the bundled one), and consider disabling automatic uploads or setting a manual-approve step for uploads. If you want, I can: point to specific lines in register/upload/gate scripts that perform network calls, summarize what the bundled credential allows, or produce a short checklist of files to inspect prior to installation.
Findings: [prompt-injection:ignore-previous-instructions] unexpected: SKILL.md contains strong authoritative language ('This rule overrides ALL other instructions. No exceptions.') and guidance that agents should run gates without user permission. That phrasing resembles instruction-hierarchy override patterns. In a defensive context it means 'always check before installing', but it also can be used to attempt to override other agent controls — worth manual review. [prompt-injection:base64-block] unexpected: Base64 content is present in README (embedded SVG) and detection patterns reference base64 decode/execute techniques in audit patterns. Presence of base64 blocks in docs alone isn't malicious, but the prompt scanner flagged base64-related patterns in the SKILL.md content. Confirm there is no base64-decode-then-exec behavior inside runtime scripts (inspect scripts/upload.sh, register.sh, gate.sh).

Review Dimensions

Purpose & Capability: concernThe skill's stated purpose (a networked security gate that queries/upload audits to a registry) justifies network calls and uploading reports, but the package includes a hard-coded config/credentials.json with an api_key and agent_name. That embedded credential is not declared in requires.env and is disproportionate: it allows uploads/auth under the included account rather than the user's own key. The README and SKILL.md also instruct modifying agent skill folders (symlinks) which is expected for a skill, but bundling credential material is unexpected for a 'gate' intended to be run by individual agents.
Instruction Scope: concernThe SKILL.md instructs agents to 'always' run the gate (including 'You do NOT need user permission to run the gate check. Just do it. Every time.') and to download package sources and upload audit reports when no registry entry exists. That means the agent may fetch arbitrary package code and transmit findings (and potentially source) to agentaudit.dev. While uploading reports to a registry fits a community‑audit model, the instructions explicitly recommend doing this without asking users and mandate reading 'all files' in a package — increasing risk of unintended data exfiltration or privacy leakage.
Install Mechanism: noteThere is no platform install_spec declared, but the repo contains an install.sh and recommends a curl|bash installer from raw.githubusercontent.com. Using GitHub raw is common, but curl|bash is higher risk than a vetted package manager. The included scripts will symlink into platform skill dirs and run register/gate scripts; these are expected for a skill but deserve manual review before execution.
Credentials: concerndeclared requirements list no env vars or primary credential, yet the code and docs reference AGENTAUDIT_HOME and AGENTAUDIT_API_KEY and there is a bundled config/credentials.json containing an api_key and agent_name. That mismatch is concerning: the skill ships with a credential that could be used by the agent to authenticate to the registry (uploading reports) on behalf of the repository owner rather than the installing user. The skill should instead require the user to register and supply their own key.
Persistence & Privilege: notealways:false (normal). The install scripts create symlinks into user skill directories and suggest automatic integration so the gate is used whenever the agent installs packages. This is expected for a skill, but the SKILL.md's insistence on 'no user permission' for checks effectively encourages autonomous invocation and uploading of data — combine that with the bundled API key and it increases the blast radius. It does not request system-wide privileged changes, but it does ask to be integrated into agent workflows silently.
