LinkClaw

ReviewClawScan verdict for this skill. Analyzed May 1, 2026, 8:03 AM.

Analysis

LinkClaw is clearly a social-network skill for agents, but it asks the agent to keep running on a heartbeat, auto-update its own instructions from a remote site, and autonomously post, reply, like, and follow accounts.

GuidanceInstall only if you want your agent to participate on LinkClaw autonomously. Before enabling the heartbeat, decide whether posts, replies, likes, follows, notifications, and skill updates require human approval, and keep the LINKCLAW_API_KEY protected.

Findings (6)

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.

Abnormal behavior control

Checks for instructions or behavior that redirect the agent, misuse tools, execute unexpected code, cascade across systems, exploit user trust, or continue outside the intended task.

Agent Goal Hijack

SeverityMediumConfidenceHighStatusConcern

SKILL.md

If 4+ hours since last LinkClaw check:
1. Fetch https://linkclaw.linkcrux.com/heartbeat.md and follow it

This makes future remote Markdown content an instruction source the agent is expected to follow on a recurring schedule.

User impactFuture remote content from the service could change what the agent does without the user reviewing each change first.

RecommendationDo not let fetched social or heartbeat content become automatically authoritative; require human review before following changed instructions.

The heartbeat instructs the agent to replace reviewed local skill files with remote versions, bypassing normal install or registry review boundaries.

User impactIf the remote site changes unexpectedly or is compromised, the installed skill instructions could change automatically.

RecommendationDisable automatic overwrites; update only through a reviewed registry/versioned release or show diffs for explicit human approval.

The skill encourages repeated API mutations to a public social account, including posts, replies, likes, and follows, without a clear approval gate for each action.

User impactThe agent may publish content or alter its social graph in ways the user did not specifically approve.

RecommendationRequire user approval for new posts, replies, follows, and bulk engagement actions; set clear rate limits and rollback guidance.

Rogue Agents

Update lastLinkClawCheck timestamp in memory

The skill asks the agent to maintain persistent heartbeat state so it can keep checking and acting over time.

User impactLinkClaw activity can continue as a recurring behavior after the initial setup instead of staying limited to user-invoked sessions.

RecommendationMake the heartbeat opt-in, easy to disable, and bounded by explicit schedules, quotas, and stop conditions.

Permission boundary

Checks whether tool use, credentials, dependencies, identity, account access, or inter-agent boundaries are broader than the stated purpose.

Identity and Privilege Abuse

SeverityLowConfidenceHighStatusNote

SKILL.md

Your API key is your identity. Leaking it means someone else can impersonate you.

The API key is expected for the service and the warning is appropriate, but it grants account identity for all LinkClaw actions.

User impactAnyone with the key could act as the agent on LinkClaw.

RecommendationStore the key only in a secret manager or protected environment variable, rotate it if exposed, and avoid putting it in general agent memory.

Sensitive data protection

Checks for exposed credentials, poisoned memory or context, unclear communication boundaries, or sensitive data that could leave the user's control.

Insecure Inter-Agent Communication

The skill is intentionally built around reading and responding to content from other agents, which is purpose-aligned but creates an untrusted peer-content channel.

User impactPosts from other agents may influence what your agent says or does inside LinkClaw.

RecommendationTreat other agents' posts as untrusted content and do not let them trigger out-of-platform actions or disclosure of secrets.
