Usage Guidance
This package is an edited fork of a known 'skill-creator' and is internally consistent with that purpose, but you should review and control runtime actions before use:
- Review the Python scripts (especially those that call subprocess.run, lsof, os.kill, or open an HTTP server) before executing to ensure you trust them and understand what external commands they will run.
- The skill expects an Opencode CLI on your machine and will invoke it (opencode run). Only allow that if you trust the Opencode binary on your system.
- The eval viewer starts a small HTTP server and embeds workspace files (including base64-encoded binaries) into a page. Ensure the server binds to localhost (and is not exposed to the public internet) before opening it, and don't point it at directories containing secrets you don't want served.
- The scripts may attempt to kill processes on a port (uses lsof/os.kill) — run as a user with appropriate privileges and be cautious if you run as root.
- Because this is code included with the skill (no packaged install), prefer running in a sandboxed environment (non-privileged account, isolated VM/container) if you plan to execute the scripts.
If you only want the guidance functionality without executing any code, you can still use the SKILL.md instructions as a human-readable workflow; executing the included scripts is optional.
Capability Analysis
Type: OpenClaw Skill
Name: skill-creator-opencode
Version: 1.0.1
This skill bundle is a development utility designed to create, test, and optimize OpenClaw skills using the Opencode CLI. It includes scripts for benchmarking, packaging, and a local HTML viewer (eval-viewer/generate_review.py) that runs a temporary local HTTP server for result visualization. While the skill performs subprocess execution and filesystem modifications (e.g., in scripts/run_eval.py and scripts/improve_description.py), these actions are necessary for its stated purpose of skill development and evaluation. The SKILL.md instructions explicitly direct the agent to avoid creating malware or facilitating unauthorized access, and no indicators of data exfiltration or malicious intent were identified.
Capability Assessment
Purpose & Capability
Name/description (a skill-creator that writes and evaluates skills) matches the included files and runtime behavior: scripts for packaging, running evals, generating reports, and a viewer that embeds workspace outputs. Requesting the Opencode CLI and searching common paths for it is coherent with the stated goal of driving an external CLI to run/validate skills.
Instruction Scope
SKILL.md instructs the agent to run the included scripts and to read/work with a workspace directory, test prompts, transcripts, and outputs — exactly what a skill-creator needs. Be aware the scripts read arbitrary files from the provided workspace and will start a tiny HTTP server to serve review pages and save feedback.json, which can expose workspace files if the server is misconfigured or made publicly reachable.
Install Mechanism
No install spec (instruction-only) — the repository includes Python scripts meant to be executed in-place. This is low-friction and expected. The scripts call subprocesses (e.g., to run lsof, kill processes, and invoke opencode), which is normal for a local tooling wrapper but is worth reviewing before execution.
Credentials
The skill declares no required environment variables and only optionally reads OPENCODE_PATH (to locate the Opencode CLI). That matches the purpose; there are no unexplained credential or secret requests.
Persistence & Privilege
always:false and no special platform-wide privileges requested. The skill does start a local server and may write feedback.json into the workspace (expected behavior), but it does not request permanent agent-wide presence or attempt to modify other skills' configs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install skill-creator-opencode - After installation, invoke the skill by name or use
/skill-creator-opencode - Provide required inputs per the skill's parameter spec and get structured output
