Subscription and Renewal Desk

• Outcome: Pass
• Latest audit: Oct 26, 2026 · 10:22 PM UTC
• Version: 1.0.1

Overview

This skill coherently tracks subscriptions locally and supports user-requested reminders without paying for or cancelling services.

Keep the local subscription database private. For reminders, specify the recipient, timezone and frequency, and verify delivery. Consider pinning the ClawHub installer version. This skill records cancellation dates but does not cancel subscriptions.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• Output Handling: Unvalidated Output Injection, Cross-Context Output, Unbounded Output
• Rogue Agent: Self-Modification, Session Persistence
• MCP Least Privilege: Underdeclared Capability, Wildcard Permission, Missing Permission Declaration

Findings (8)

MCP server referenced without pinned version: 'npx clawhub'.

Medium

• Category: MCP Rug Pull
• Confidence: 95% confidence

Finding

The installation example uses npx clawhub@latest, which executes a mutable package version rather than a reviewed, pinned release. A compromised upstream release could execute code with the installing user's permissions, potentially accessing workspace files and available credentials. This is a CLI installation command, not an MCP server reference, but the underlying supply-chain concern remains valid; nothing in the README demonstrates malicious intent.

MCP server referenced without pinned version: 'npx clawhub'.

Medium

• Category: MCP Rug Pull
• Confidence: 94% confidence

Finding

The installation command uses npx clawhub@latest, which can download and execute a changing npm release without a reviewed version pin. A compromised future release could execute code with the user's permissions and access workspace files or available credentials; however, this is an optional, user-initiated installation step with no evidence of malicious intent. The scanner incorrectly describes the CLI as an MCP server, but the underlying unpinned executable dependency risk remains valid.

Content

No source excerpt is available for this finding.

Skill declares no tool scope ('permissions' or 'allowed-tools') but code capabilities were detected: env, file_read, file_write, shell.

Medium

• Category: MCP Least Privilege
• Confidence: 70% confidence

Finding

Without declared permissions the skill's intent is opaque and cannot be validated.

Content

No source excerpt is available for this finding.

Autonomous Decision Making

Medium

• Category: Excessive Agency
• Confidence: 80% confidence

Finding

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.

king account. Data and notifications persist under .mochilab. Do not upload those private state folders with a Skill package.

Use for planned recurring charges rather than historic expense accounting. Store the first charge date, amount, currency, cycle and cancellation lead days. Forecasts preserve the original day-of-month: a Jan 31 monthly plan uses Feb's last day and then Mar 31. Feb 29 annual plans return to Feb 29 in a leap year. Currency totals remain separate; never invent exchange rates. end is the inclusive final charge date, not an automatically executed cancellation.

poll lists approaching renewal and cancellation deadlines with persistent notice IDs. Read references/notifications.md to create an actual user-authorized host schedule and destination. A reminder does not pay or cancel a subscription. After editing a price/cycle, review the next forecast and replace any stale pending notices before sending. User-selected subscriptions and state stay in this agent workspace.

Session Persistence

Medium

• Category: Rogue Agent
• Confidence: 80% confidence

Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

# Host scheduling and delivery

These scripts keep state and queues; Python by itself does not create a timer. For a user-requested recurring reminder, use the installed OpenClaw scheduler, inspect its current help, and create a job for THIS agent/workspace and the requested chat/account only. Get the timezone, frequency and recipient from the user's request; ask only for missing details. Verify the returned job ID and next run. Never reuse another agent's mailbox credentials or destination.

The job runs poll (email: sync) with the same private profile and workspace. If there are no pending notices, finish quietly. Deliver pending notices through the host's configured messaging tool. After each successful delivery, call ack with only its noticeId. If delivery fails, leave it pending. Maintain the noticeId in the host delivery ledger to avoid duplicate delivery after a retry; this is at-least-once delivery, not a cross-service transaction. Never acknowledge before sending. Manual tests

The atomic-write helper silently replaces existing destination files without explaining the overwrite behavior.

Medium

• Category: Output Handling
• Confidence: 88% confidence

Finding

The helper writes data and uses os.replace to overwrite an existing destination, potentially losing its previous contents. This file provides no confirmation, operation-specific log, docstring, or comment disclosing that replacement behavior; atomic replacement protects write consistency, not the previous data.

Content

No source excerpt is available for this finding.

Credential-environment access is unrelated to the declared subscription-tracking capabilities.

Medium

• Category: Excessive Agency
• Confidence: 86% confidence

Finding

The secret() helper retrieves a credential from an environment variable whose name is supplied through configuration. Tracking renewals, calculating deadlines, forecasting costs, and queuing notices do not inherently require credential access, and no authenticated integration is declared. This file implements the capability but does not show it being invoked.

Content

No source excerpt is available for this finding.

Scope Creep

Low

• Category: Excessive Agency
• Confidence: 70% confidence

Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
