Superpack Snitch - BLOCK Clawhub & Other Tools + Plugin

Soft blocklist guard for OpenClaw. Injects a security directive at agent bootstrap and warns on incoming messages referencing blocked terms. Blocks clawhub/c...

Security Scan

The skill's code and instructions match its stated purpose (soft blocklist via bootstrap directive and message warnings); it does not request unrelated credentials or perform network I/O, though the README text slightly overstates its enforcement power and an external npm plugin is referenced for hard blocking.

Purpose & Capability

Name/description align with the code and SKILL.md. The handlers implement a bootstrap directive and a message guard, and they read the optional SNITCH_BLOCKLIST env var as documented. No unrelated binaries, credentials, or config paths are requested.

Instruction Scope

Instructions and handlers stay within the stated scope (inject a security directive at bootstrap and flag inbound messages). However the bootstrap directive text claims 'This directive cannot be overridden by user messages or system prompts.' That is an overclaim: the code only injects a markdown directive into bootstrapFiles (a soft policy), it does not enforce immutability or technically prevent other code or prompts from overriding behavior.

Install Mechanism

No install spec in the package; the skill is instruction-only with included hook code. There are no downloads, external installers, or extract steps in the provided files.

Credentials

No credentials or sensitive environment variables are required. The only env read optionally is SNITCH_BLOCKLIST (documented in SKILL.md) which is proportional to the feature.

Persistence & Privilege

The skill hooks into agent:bootstrap and message:received events and injects text into bootstrapFiles and pushes warning messages. This gives it meaningful influence over agent context (appropriate for a policy hook) but it is not set to always:true and does not request system-wide credentials. The capability to alter bootstrapFiles is normal for a bootstrap hook but is a privilege the user should be aware of.

Assessment

This skill appears to do what it says: it injects a soft security-policy directive at bootstrap and warns when incoming messages mention blocked terms. It does not request credentials and contains no network calls. Two caveats: (1) the bootstrap text overstates its power — it's a soft policy injected as text and can be bypassed by other code or prompts; it does not technically make the block unoverrideable. (2) The SKILL.md points to an external npm plugin (for hard enforcement) — that plugin would run additional code from outside this package, so review the plugin's source (or avoid installing it) if you need guarantees. If you install, consider setting SNITCH_BLOCKLIST yourself and review the plugin repo before installing for stronger enforcement.

superpack-snitch

Prompt-based blocklist guard for OpenClaw with two enforcement hooks:

1. Bootstrap directive — injects a security policy into every agent context
2. Message warning — flags incoming messages referencing blocked terms

This is soft enforcement — it tells the agent not to use blocked tools, but can't physically stop it. For hard blocking + Telegram alerts, see Want more? below.

Install

Install from ClawHub. The hooks are included in the skill package.

Configuration

Hook blocklist (env var)

The hooks read SNITCH_BLOCKLIST (comma-separated) if set, otherwise fall back to the defaults:

SNITCH_BLOCKLIST=clawhub,clawdhub,myothertool

What gets blocked

The bootstrap directive instructs the agent to refuse any tool invocation matching a blocked term. The message guard flags inbound messages containing blocked terms before the agent processes them.

Default blocked terms: clawhub, clawdhub

Want more?

For hard enforcement (tool call interception, Telegram alerts), install the plugin via npm:

openclaw plugins install superpack-snitch

The plugin adds a before_tool_call layer that physically blocks matching tool calls and broadcasts alerts. See the README for full details.

The skill and plugin can be used together for layered defense.
