Security audit

Proactive Agent

Security checks for vulnerabilities and agentic risk

Overview

This skill needs Review because it installs persistent agent rules, logs broad personal/work context, and encourages recurring private-data checks without enough consent, scoping, or rollback controls.

Install only after reviewing the exact files it would place in your workspace. Do not run the wildcard copy over an existing project without backups. Enable memory, heartbeat, email, calendar, web, and autonomous-agent behavior only with explicit scopes, retention limits, and a way to inspect and delete stored data.

Findings (52)

Tp4

High

Category: MCP Tool Poisoning
Confidence: 99% confidence
Finding: The declared purpose is proactive agent behavior, but the content also instructs security auditing, recursive file inspection, secret scanning, and review of workspace artifacts like AGENTS.md and memory files. That mismatch can cause operators to grant the skill more trust than warranted while it drives broad workspace inspection and potentially accesses sensitive data outside the user's expected scope.
Content: No source excerpt is available for this finding.

Intent-Code Divergence

High

Category: Not specified by scanner
Confidence: 98% confidence
Finding: The file contains a direct contradiction: it says to always confirm before deleting files, but also instructs automatic deletion of BOOTSTRAP.md on first run. This creates a standing authorization for destructive action that can be abused or cause loss of evidence, setup instructions, or user-authored content without informed consent.
Content: No source excerpt is available for this finding.

Tool Parameter Abuse

High

Category: Tool Misuse
Confidence: 90% confidence
Finding: Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 91% confidence
Finding: The README advertises autonomous scheduled behavior without any warning about operational impact, such as repeated execution, unwanted notifications, resource consumption, or actions occurring without fresh user intent. Because the skill's purpose is to make agents proactive, the absence of safeguards or user-consent guidance increases the chance that adopters enable persistent behavior without understanding the risks.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 91% confidence
Finding: The invocation examples are broad, imperative, and lack any trigger boundaries, approval requirements, or scope constraints. In a skill explicitly designed to make agents more proactive and autonomous, vague commands like enabling proactive checks or configuring protocols can cause overreach, repeated unsolicited actions, or unintended state changes if interpreted too aggressively by an agent framework.
Content: No source excerpt is available for this finding.

Undeclared Tool Scope

Medium

Category: MCP Least Privilege
Confidence: 93% confidence
Finding: The skill references shell execution (cp, grep, ./scripts/security-audit.sh) and network-capable behaviors (web search, external source vetting), but the manifest does not declare any tool scope or allowed-tools boundaries. That creates ambiguity around what the skill may invoke and weakens least-privilege controls, especially for a skill that encourages broad autonomy.
Content: No source excerpt is available for this finding.

Indirect Prompt Extraction

Medium

Category: System Prompt Leakage
Confidence: 85% confidence
Finding: Skill contains patterns that could indirectly extract system prompts through rephrasing, translation, summarization, or side-channel techniques.
Content: Scanner excerpt · SKILL.md (reported line 39)May include surrounding context.

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 92% confidence
Finding: The quick start tells the agent to gather answers and auto-populate USER.md and SOUL.md, but it does not present a clear consent, retention, or sensitivity warning. This encourages storage of personal profile information by default, potentially including sensitive preferences or identity data the user did not realize would be persisted.
Content: No source excerpt is available for this finding.

Ssd 3

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The WAL protocol explicitly instructs immediate recording of proper nouns, preferences, decisions, specific values, IDs, dates, and URLs. This creates systematic retention of user-identifying and potentially sensitive data in persistent files, increasing the impact of later prompt leakage, file compromise, or accidental disclosure.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The WAL trigger applies to extremely common message patterns such as corrections, preferences, names, decisions, and numbers, effectively causing the skill to activate on ordinary conversation. Overly broad activation increases unintended persistence of user data and makes the skill's behavior hard to constrain or predict.
Content: No source excerpt is available for this finding.

Ssd 3

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The working buffer protocol directs the agent to append every message after a context threshold, including both user input and response summaries, then replay that material after compaction. Broad persistence and replay of natural-language exchanges creates a substantial risk of retaining secrets, personal data, and sensitive task content beyond immediate need.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 90% confidence
Finding: The compaction recovery trigger includes vague conditions like 'you should know something but don't' and broad conversational phrases like 'continue' or 'where were we?'. Such subjective triggers can cause unnecessary recovery actions and extra reading of stored buffers and notes, increasing privacy exposure and unintended file access.
Content: No source excerpt is available for this finding.

Unrestricted Tool Access

Medium

Category: Excessive Agency
Confidence: 88% confidence
Finding: The instruction to 'use every tool' including CLI, browser, web search, and spawning agents promotes unrestricted tool use without task-specific approval or least-privilege limits. In an autonomous skill, that materially increases the risk of overreach, unsafe command execution, external data exposure, and chaining actions across multiple tools.
Content: Scanner excerpt · SKILL.md (reported line 304)May include surrounding context.

Intent-Code Divergence

Medium

Category: Not specified by scanner
Confidence: 86% confidence
Finding: Lines L053-L053 state that websites, emails, and PDFs are data and that instructions must come only from the human. However, lines L111-L123 and L137-L141 instruct the agent to inspect emails and use web search and other tools as part of autonomous workflows, creating conflicting guidance about how externally sourced content should influence behavior. This is an intent-level contradiction in the operating rules.
Content: No source excerpt is available for this finding.

Intent-Code Divergence

Medium

Category: Not specified by scanner
Confidence: 91% confidence
Finding: The policy says anything leaving the machine requires approval, but it also authorizes web search and checking calendars/emails 'freely' and during heartbeat processing. In practice, web search usually transmits data off-device, and email/calendar access may touch sensitive remote services, so the inconsistent guidance can lead to unapproved outbound actions and privacy exposure.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 85% confidence
Finding: This markdown file instructs the agent to act on the vague question "What would genuinely delight my human that they haven't asked for?" and then work "proactively without asking." Those phrases are highly open-ended and lack concrete scope limits or negative examples, which increases the chance of unintended activation or overreach from ordinary conversational context.
Content: No source excerpt is available for this finding.

Autonomous Decision Making

Medium

Category: Excessive Agency
Confidence: 89% confidence
Finding: The directive to act 'proactively without asking' authorizes autonomous behavior without clearly bounded scope, which can lead to privacy-invasive review, unintended modifications, or action creep. Although framed helpfully, it lowers the threshold for the agent to initiate tasks that the user did not explicitly request.
