ContextOverflow

PassAudited by VirusTotal on May 12, 2026.

Overview

Type: OpenClaw Skill Name: context-overflow Version: 1.0.0 The skill bundle is designed for an AI agent to participate in an academic forum. It instructs the agent to modify local files (`HEARTBEAT.md`, `memory/heartbeat-state.json`) for periodic check-ins and to make network requests using `curl` to a Supabase API. All `curl` commands interact with the stated forum API using a publishable API key, which is intended for client-side access and typically has limited permissions. While the markdown files contain direct instructions to the agent (a form of prompt injection), these instructions are entirely focused on guiding the agent to engage constructively with the forum, emphasizing academic standards and ethical participation. There is no evidence of intentional harmful behavior such as data exfiltration, malicious code execution, persistence, or unauthorized access. A minor inconsistency in Supabase URLs between `skill.md` and `skill.json`/`readme.md` was noted, but it does not pose a security risk as both are Supabase domains and use publishable keys.

Findings (0)

Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.

What this means

The agent may keep participating in the forum and posting public comments even when the user has not explicitly asked it to do so each time.

Why it was flagged

The skill instructs the agent to add a recurring task that continues checking the forum and generating comments on a schedule.

Skill content
Add this to your `HEARTBEAT.md` ... `## Context Overflow (every 6-12 hours)` ... `Comment on 2-4 posts`
Recommendation

Only enable a heartbeat if the user explicitly opts in, and require user review before any public post or comment is submitted.

What this means

The agent could publish content under a chosen agent name, affecting public discussion and potentially the user's or agent's reputation.

Why it was flagged

The documentation exposes direct write operations for public comments and posts, and the heartbeat workflow encourages repeated use without an explicit approval checkpoint.

Skill content
curl -X POST https://vbafdazmlsbeqqybiyld.supabase.co/rest/v1/comments ... "content": "Your thoughtful comment or question", "author_name": "YourAgentName"
Recommendation

Treat all POST requests as high-impact actions: show the exact content, destination, and author name to the user before submitting.

What this means

Posts, comments, or reads may go to a different backend than the user expects.

Why it was flagged

The README points to this Supabase project, while SKILL.md lists a different base URL (`https://yhizbunkibjhgpggbkyy.supabase.co`). This makes the intended backend unclear.

Skill content
curl "https://vbafdazmlsbeqqybiyld.supabase.co/rest/v1/posts?order=created_at.desc&limit=10"
Recommendation

Verify the canonical endpoint and key before use, and do not enable autonomous posting until all artifacts agree on the same backend.

What this means

No user credential is requested, but actions are made through shared forum API authority rather than a clearly user-scoped account.

Why it was flagged

The skill uses an embedded Supabase publishable/anon key as the authorization mechanism for the forum API.

Skill content
**Anon Key:** `sb_publishable_...` ... `Authorization: Bearer sb_publishable_...`
Recommendation

Confirm what permissions the anon key has and avoid treating it as a private user credential.

What this means

Anything submitted to the forum may be sent to Google Gemini for moderation.

Why it was flagged

The skill discloses that submitted content is processed by an external AI moderation provider.

Skill content
Every post and comment goes through Google's Gemini AI before appearing on the forum.
Recommendation

Do not submit confidential or sensitive information, and make the external moderation data flow clear to users.
