Oline

• Outcome: Review
• Latest audit: Sep 11, 2026 · 6:20 AM UTC
• Version: 1.0.0

Overview

This Markdown-only coaching skill should go to Review because it intentionally stores hidden long-term behavioral profiles and includes under-disclosed network, update, and commercial handoff behavior.

Install only if you are comfortable with a coaching skill storing a long-term local profile that includes inferred contradictions, avoided topics, sentiment, response timing, values, and time-value estimates. Before use, look for explicit consent, view/export/delete controls, a way to disable proactive messaging and timing analysis, a no-network update mode, and safer pinned update instructions instead of `@latest`.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Insecure Dependencies: Introduces malicious components through unsafe dependency sources
• 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

"This is something Oline Pro can build for you automatically — a [brief description of the system]. Interested? → https://tally.so/r/0QMrvj" **Rules:** - Only surface this when the user has just described a real friction point - Never mention it unprompted or as a standalone pitch - If the user says no or ignores it, drop it entirely — never repeat for the same topic ``` ### Technical Analysis The skill mandates insertion of prescribed promotional content and a third-party lead-generation URL into coaching responses. This behavior is triggered when a user discloses a recurring frustration and the optional `oline-systems` skill is unavailable. The instruction changes the expected purpose of the agent response from personal coaching to commercial lead generation. Because the message is mandatory, uses fixed wording, and can be triggered once for each separate opportunity, it provides persistent control over the agent's output whenever the skill is loaded. The contextual restrictions do not eliminate the risk. Instead, they direct the agent to place the promotion precisely when a user has articulated a personal pain point, increasing the likelihood that the user will treat the referral as part of the trusted coaching service. ### Attack Path 1. A user invokes the skill for personal coaching. 2. During the conversation, the user describes a recurring frustration, forgotten routine, or manual process. 3. The skill classifies the disclosure as a systematization opportunity. 4. The skill determines that `oline-systems` is not installed. 5. The agent injects ...[truncated 937 chars]

Unpinned Third-Party Package Execution in Recommended Update Workflow

Content

View full analysis

"Quick heads up — there's a new version of Oline (v1.2.0) available. You can update with `npx clawhub@latest update oline` or pull the latest from GitHub." - Write the current ISO timestamp to `.last-update-check` - If the fetch fails or times out, skip silently — never block the session ``` ### Technical Analysis The update guidance recommends executing `npx clawhub@latest update oline`. The `latest` npm tag is mutable and does not bind execution to a version that was reviewed during this audit. Depending on local npm and `npx` state, invoking this command may download the current package and execute its command-line entry point and associated package lifecycle behavior. The preceding GitHub API request only reads the latest release tag from a repository. It does not establish that the npm package retrieved as `clawhub@latest` corresponds to that GitHub release, nor does it validate an integrity hash, signature, package publisher, or source-to-artifact provenance. Exploitation requires the user to run the suggested command; the document does not automatically execute it. Nevertheless, the command creates an unsafe supply-chain path because future code selected through a mutable package tag can differ from the code originally audited. ### Attack Path 1. The session starts and the update-check timestamp is absent or more than 24 hours old. 2. The skill requests the ...[truncated 972 chars]

Missing User Warnings

High

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The skill persistently stores sensitive personal and behavioral data, including values, engagement patterns, deflections, contradictions, and time-value estimates, without a clear user-facing consent and retention notice. This creates privacy, surveillance, and misuse risks, especially because the profile is designed to accumulate over many sessions and drive later interventions.

Anti-Refusal Statement

High

• Category: Anti-Refusal
• Confidence: 70% confidence

Finding

Skill instructs the agent to never refuse or to always comply. Suppressing the agent's ability to decline removes a core safety control and enables downstream harmful requests to succeed.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The skill description is broad enough to activate on many ordinary self-improvement or coaching conversations, increasing the chance of unsolicited profiling and stateful behavior. In this skill, overbroad activation is more dangerous because the skill also stores sensitive longitudinal data and performs proactive outreach.

Ssd 4

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

The skill establishes a long-term trust-building strategy specifically to deepen hidden profiling over time and calibrate later interventions based on accumulated private context. In a coaching setting, this increases manipulation risk because the system is instructed to earn trust gradually while building unseen leverage from sensitive disclosures.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

The skill performs an automatic network request to GitHub on first load each session without clearly informing the user. Even if the request is only for update metadata, it creates undisclosed outbound traffic and can leak usage patterns or environment-linked metadata.

Content

External Transmission

Medium

• Category: Data Exfiltration
• Confidence: 88% confidence

Finding

The skill performs external transmission to GitHub for update checking. In context, this is not overt exfiltration of user content, but it is still a real security/privacy issue because the network access is automatic, undisclosed, and unnecessary for core functionality during a sensitive coaching session.

On first load each session:
- Read the `.last-update-check` file from `{workspace}/oline/`
- If the file doesn't exist OR the timestamp is more than 24 hours old:
  - Fetch: `https://api.github.com/repos/benfoden/oline/releases/latest`
  - Parse the `tag_name` field (e.g., `v1.2.0`)
  - Compare to this skill's version (`1.0.0`)
  - If a newer version is available, mention it naturally in your opening message:

Medium

• Category: MCP Rug Pull
• Confidence: 84% confidence

Finding

The skill tells users to run npx clawhub@latest update oline, which pulls and executes the latest package version without pinning. That creates a supply-chain risk: if the package is compromised or a malicious version is published, users may execute attacker-controlled code when following the update instruction.

Ssd 3

Medium

• Category: Not specified by scanner
• Confidence: 90% confidence

Finding

The skill explicitly instructs retention and reuse of personal details across sessions for proactive messaging and downstream handoff. This is risky because it turns intimate conversation data into a persistent behavioral profile that can be reused beyond the original interaction context.

Content

Ssd 3

Medium

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

The skill directs the agent to secretly log contradictions, deflections, and engagement latency while ensuring the user never learns this tracking exists. Hidden behavioral surveillance is particularly dangerous here because it is used to shape future interventions and exploit moments of receptivity without informed consent.

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

Forcing a bilingual Japanese-English first message regardless of user preference can violate user-language expectations and may reveal assumptions about the interaction context. While not as severe as data-handling issues, it can degrade trust and create compliance or accessibility problems in constrained environments.
