Agentic Workflow Automation

Security checks for vulnerabilities and agentic risk

Overview

The skill is coherent overall, but its helper script can still write or overwrite files even when dry-run mode is requested.

Review or fix the generator before production use. Do not rely on --dry-run as safe, and only invoke the script with output paths confined to a disposable or intended artifact directory.

  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review

Every execution therefore creates missing parent directories and writes to or truncates the path supplied through `--output`, including when `--dry-run` is e ...[truncated 2339 chars]

Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
82% confidence
Finding

The skill instructs use of local scripts and bundled references, which implies file read/write capability, but it does not explicitly declare a tool or permission scope. This can lead to over-broad execution in hosts that rely on manifest-level scoping, increasing the chance that an agent can read or modify files beyond what the skill actually needs.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The script advertises '--dry-run' as having no side effects, but the flag is only propagated into the result object and does not prevent file creation or modification. In automation contexts, operators may rely on dry-run safety guarantees before running against sensitive paths, so this mismatch can overwrite artifacts or trigger downstream processes unexpectedly.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

At the write path, the program always emits the output artifact regardless of the '--dry-run' flag and provides no warning to the user. This is dangerous mainly as a safety/integrity issue: in agentic workflow automation, a supposed simulation mode may still alter files, causing unintended handoff artifacts, overwrites, or CI/CD side effects.
