Description
Reference tool for devtools — covers intro, quickstart, patterns and more. Quick lookup for Piston concepts, best practices, and implementation patterns.
Usage Guidance
This skill appears to be a harmless offline reference: it only prints embedded documentation and does not use network calls or secrets. If you plan to run the included script on a machine, you can inspect it (it's plain bash) and run it in a restricted/sandboxed environment if you want extra caution. Note the quickstart text mentions "access credentials" in a generic way — that is not implemented or required by this skill.
Capability Analysis
Type: OpenClaw Skill
Name: piston
Version: 2.0.1
The 'piston' skill is a static documentation reference tool for devtools concepts. The implementation in `scripts/script.sh` consists entirely of bash functions that output plain-text documentation via heredocs, with no network access, file system modifications, or credential handling. The instructions in `SKILL.md` accurately reflect the code's behavior and contain no prompt-injection attempts or malicious directives.
Capability Assessment
Purpose & Capability
The name/description (Piston reference for devtools) matches the included assets: a markdown SKILL.md and a bash script that emits documentation. Nothing in the files requires cloud access or unrelated credentials. Minor note: the quickstart text generically mentions "access credentials," but the skill itself declares no required env vars and contains no code that uses credentials.
Instruction Scope
SKILL.md instructs the agent to output plain-text reference content and explicitly states no external API calls or network access. The bundled script implements only heredoc documentation output and a simple command dispatcher; it does not read arbitrary files, environment variables, or external endpoints.
Install Mechanism
No install spec is provided (instruction-only style). The only code is an included shell script; there are no downloads, package installs, or extraction steps that would write external code to disk at install time.
Credentials
The skill declares no required environment variables, credentials, or config paths and the code does not access any. No disproportionate secret access is requested.
Persistence & Privilege
The skill does not request always:true, does not modify other skills or system configuration, and contains no setup that would persist credentials or change agent-wide settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install piston - After installation, invoke the skill by name or use
/piston - Provide required inputs per the skill's parameter spec and get structured output
