Description
Evaluate math expressions, compute statistics, and calculate percentages.
Usage Guidance
This skill works by sending your math expressions and numeric data to https://math.agentutil.net for evaluation. It does not require any credentials or local installs, which is expected, but you should not send sensitive secrets (passwords, API keys, private identifiers) inside expressions or variables because they will be transmitted to a third party. The SKILL.md's claim that inputs aren't logged can't be verified here — if you need privacy, run math evaluation locally or use a trusted local library. Note the paid tier mentions a crypto payment protocol (x402/USDC on Base); if you ever choose paid features, verify the service and payment flow separately.
Capability Analysis
Type: OpenClaw Skill
Name: math-evaluate
Version: 1.0.0
The skill `math-evaluate` is designed to perform math evaluations, statistics, and percentage calculations by sending data to an external API at `https://math.agentutil.net`. The `SKILL.md` file transparently declares this external communication and provides `curl` examples for interaction. The data sent (math expressions, numbers) is directly relevant to the skill's stated purpose and does not appear to include sensitive local information. There is no evidence of prompt injection attempts against the agent, malicious execution, data exfiltration of local secrets, or persistence mechanisms.
Capability Assessment
Purpose & Capability
Name/description match the behavior: the SKILL.md documents POSTing expressions and arrays to math.agentutil.net to evaluate expressions, compute statistics, and calculate percentages. There are no unrelated required binaries, env vars, or installs.
Instruction Scope
Instructions explicitly send expressions and data to an external API (math.agentutil.net) — this is consistent with the stated purpose. The SKILL.md does not instruct reading files or environment variables. However, the privacy claim ('service does not store or log input') is unverifiable in static review and the user should assume any data sent could be observed or retained by the remote service.
Install Mechanism
Instruction-only skill with no install spec or code files; nothing is written to disk or executed locally during install.
Credentials
No environment variables, credentials, or config paths are requested — proportional to a simple remote math-evaluation API.
Persistence & Privilege
always is false and the skill does not declare elevated persistence or permissions. It does not request changes to other skills or system configs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install math-evaluate - After installation, invoke the skill by name or use
/math-evaluate - Provide required inputs per the skill's parameter spec and get structured output
