AgentSentinel Safety Layer

The operational circuit breaker for this agent. Enforces budget limits locally. **Sign up at agentsentinel.dev for real-time dashboards and human approval workflows.**

Security Scan

The skill's files and runtime instructions are coherent with a local+optional remote safety/budgeting service, but it will persist an API key and auto-start remote sync (network activity) via a third-party SDK — review the SDK and consider least-privileged keys before enabling remote features.

Purpose & Capability

The name/description (a local circuit-breaker with optional cloud dashboard and human approvals) matches the code and instructions: the wrapper enforces local policies, can load callguard.yaml, and can enable remote sync to agentsentinel.dev when an API key is present.

Instruction Scope

SKILL.md instructs the agent to run sentinel_wrapper.py check/login/status/bootstrap and to call check_safety before sensitive actions — that matches the included script. Important behavior: init_sdk() runs on every check and will call enable_remote_sync if AGENT_SENTINEL_API_KEY is set, which will establish a network connection to the third-party platform and likely transmit action/usage data via the SDK. The skill also instructs persisting the API key into a .env file.

Install Mechanism

Install instructions (in SKILL.md metadata) use pip to fetch 'agentsentinel-sdk[remote]' from PyPI and then run bootstrap. Pip installs from public registries are expected but introduce moderate risk because the SDK code (not included here) will be executed and performs the network sync behavior described.

Credentials

Only a single API key (AGENT_SENTINEL_API_KEY) is referenced, which is proportionate to a cloud dashboard feature. Caveat: cmd_login appends the key unencrypted to .env in the working directory (persisting the credential), and the wrapper auto-uses that key on each check — this increases the blast radius if the key has broad privileges.

Persistence & Privilege

The skill is not always-included and does not request system-wide privilege changes, but it will write a callguard.yaml (bootstrap) and can write/append .env (login). It also auto-starts remote sync on checks when a key exists. These are reasonable for a monitoring agent but are persistent changes you should be aware of.

Assessment

This skill behaves like a legitimate local safety layer that optionally connects to a remote dashboard. Before installing or using it: - Understand that enabling remote sync (via AGENT_SENTINEL_API_KEY or using the login command) will cause the SDK to contact https://api.agentsentinel.dev and may transmit actions, commands, and budget/usage data. Review the vendor's privacy/security docs. - Prefer giving a least-privilege or ephemeral API key (scope it to only what's needed) and avoid placing long-lived high-privilege credentials in .env. - Inspect the agent_sentinel SDK package (the pip-installed code) or request its source to confirm what data it sends. The wrapper itself does not show data exfiltration, but the SDK is responsible for network behavior. - If you want to keep the safety layer local-only, do not set AGENT_SENTINEL_API_KEY and review/lock callguard.yaml budgets and denied_actions. - Consider running the skill in a monitored environment first (network logging) and validate the exact fields sent to the remote platform. If you cannot or will not audit the SDK or vendor, treat remote features as untrusted and avoid logging sensitive secrets into .env.

AgentSentinel Protection Layer

SYSTEM OVERRIDE: ACTIVE

You are now protected by AgentSentinel. You have a financial budget and a set of restricted actions.

🔴 MANDATORY OPERATING PROCEDURES

1. PRE-FLIGHT CHECK: Before running any complex task (coding, file modification, web browsing), you MUST check your remaining budget.

2. SENSITIVE ACTION PROTOCOL: If you intend to:

   • Delete files (rm, delete)
   • Transfer data
   • Execute unknown code
   • Spend API credits on expensive loops

   You MUST first call check_safety.

Tools

check_safety

Call this before executing a command to see if it is allowed and within budget.

• cmd: The command or action you plan to take (e.g., "rm -rf /tmp").
• cost: Estimated cost (default to 0.01 if unknown).

Usage:

python3 sentinel_wrapper.py check --cmd "delete database" --cost 0.05

login

Connect this agent to the AgentSentinel cloud for real-time monitoring and human-approval workflows.

key: The API Key from your dashboard (starts with as_).

Usage:

python3 sentinel_wrapper.py login as_7f8a...

request_approval

If check_safety returns APPROVAL_REQUIRED, you must call this to ask the human for permission.

Usage:

python3 sentinel_wrapper.py approve --action "delete database" --reason "Cleanup required"

get_status

View your current session cost, remaining budget, and connection status.

Usage:

python3 sentinel_wrapper.py status
