Proactivity.BAK

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed local proactivity and memory workflow that creates private notes and asks before external or high-impact actions.

Install only if you want the agent to keep local cross-session proactivity notes in ~/proactivity/. Review the optional AGENTS, TOOLS, SOUL, and HEARTBEAT snippets before approving them, and avoid placing secrets or sensitive personal data in the proactivity files.

Vulnerability Patterns
  • 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
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • System Prompt LeakageDirect Leakage, Indirect Extraction, Tool-Based Exfiltration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

This skill NEVER:
- edits any file outside `~/proactivity/` without explicit user approval in that session
- applies hidden workspace changes without showing the exact proposed lines first
- sends messages, spends money, deletes data, or makes commitments without approval
- keeps sensitive user data out of proactive state files

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The 'Message Only When' section uses subjective conditions such as 'something changed' and 'the cost of waiting is real' without defining scope, thresholds, or concrete trigger examples. In a markdown skill file, this can lead to inconsistent or unintended invocations because the activation boundary is not clearly specified.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The activation section explicitly invites broad auto-activation behavior such as jumping in on blocked work, context drift, or missing next steps, but it does not require narrow, testable trigger conditions or explicit consent boundaries. In a proactive agent skill, this can cause the agent to act on ambiguous signals, expand scope, or repeatedly intervene in ways the user did not clearly authorize.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
83% confidence
Finding

The listed triggers use broad natural-language categories such as 'Stalled work', 'Context drift', and 'Promise made' without defining clear activation boundaries or exclusions. Although examples are provided, the file does not specify negative examples or scope constraints, which could lead to unintended invocation in ordinary conversational contexts.
