Usage Guidance

This skill appears internally consistent and low risk: it bundles a local shell script that prints Cairo reference material and templates, asks for no credentials, and has no install steps. Before running, you should still: (1) open and read the full scripts/script.sh file yourself to confirm there are no network calls or commands you don't expect (the provided snippet was truncated at the end), (2) run it in a sandbox or restricted environment if you are cautious, and (3) avoid granting elevated or persistent privileges to any skill unless you trust its source. If you allow autonomous agent invocation, note that the agent could execute the script automatically when triggered — this is normal but worth knowing.

Capability Analysis

Type: OpenClaw Skill Name: cairo Version: 2.0.1 The Cairo skill bundle is a legitimate reference tool for StarkNet smart contract development. The core logic in `scripts/script.sh` consists of static text outputs providing syntax guides, type definitions, and contract templates (ERC-20, Ownable, Counter) without any network calls, file system modifications, or data exfiltration attempts.

Capability Assessment

✓ Purpose & Capability

Name/description promise reference material and templates for Cairo; the runtime instructions invoke a local scripts/script.sh which prints syntax, types, storage, events and templates — this is exactly what a reference/template skill would need.

✓ Instruction Scope

SKILL.md only instructs running the included shell script (bash scripts/script.sh <command>). The script outputs documentation and templates and does not read unrelated system files or environment variables in the visible content.

✓ Install Mechanism

No install spec is provided (instruction-only with one bundled script). This is low-risk; nothing is downloaded or extracted during install. The only runtime dependency is bash, which is normal and declared implicitly by the command examples.

✓ Credentials

The skill declares no required environment variables, no primary credential, and the script does not access secrets or external credentials in the reviewed content.

✓ Persistence & Privilege

always is false, the skill does not request permanent presence or modify other skills or system configs. It runs on-demand per SKILL.md.

How to Use

Make sure OpenClaw is installed (local or Docker)
Run the install command in chat: /install cairo
After installation, invoke the skill by name or use /cairo
Provide required inputs per the skill's parameter spec and get structured output
