Description
Updates a specific skill within a repository and triggers the automated publishing pipeline. Use when the user wants to release a new version of a single skill.
Usage Guidance
This skill will run whatever scripts/release.sh exists in the repository path you provide — that script can do anything (including push code, read files, or send data to external servers). Before using the skill: 1) inspect the target repository's scripts/release.sh (and any scripts it calls) so you understand exactly what will run; 2) avoid pointing it at sensitive system or root paths; 3) run the release script manually first (or in an isolated CI environment) to confirm behavior; 4) ensure any tokens used (GITHUB_TOKEN, deploy keys) follow least privilege and are not broadly available to the agent; 5) if you don't trust the repo or cannot review the release script, do not run this skill. Additional information that would reduce concern: explicit documentation of required credentials and a safer execution mode (dry-run, sandbox, or validation of the release script) or code that restricts which repository paths are allowed.
Capability Analysis
Type: OpenClaw Skill Name: wells1137-skill-updater Version: 1.0.0 The `scripts/update.sh` file is highly suspicious due to a critical arbitrary script execution vulnerability. It prompts the user for a `REPO_PATH` and then executes `bash "$REPO_PATH/scripts/release.sh"` within that user-provided directory. This allows a malicious user to specify a path to a repository containing their own crafted `release.sh` script, leading to arbitrary code execution on the system running the agent. While the arguments passed to `release.sh` are quoted, the path to the script itself is unsanitized user input, making it a severe shell injection risk.
Capability Assessment
Purpose & Capability
The name/description, SKILL.md, and scripts/update.sh all align: the skill asks for a repo path, skill name, version and changelog, and runs the repository's release script. No unrelated capabilities, binaries, or environment variables are requested by the skill itself.
Instruction Scope
The runtime instructions (and update.sh) change directory into the provided REPO_PATH and execute scripts/release.sh with no validation or sandboxing. That release script is arbitrary code under the repository's control and may perform any action (push tags/commits, run network requests, read local files, exfiltrate secrets). The SKILL.md and update.sh do not limit or verify the release script's behavior or the repository path.
Install Mechanism
This is instruction-only with no install spec and no external downloads — low install-time risk because nothing is written to disk by the skill package itself.
Credentials
The skill declares no required environment variables, yet a real release/publish operation will commonly rely on credentials (e.g., GITHUB_TOKEN, repo deploy keys) or other secrets. The skill does not document or request these, and the release script executed may read any environment variables available in the agent's environment, which is a mismatch and increases risk.
Persistence & Privilege
always:false and no config paths are requested, so the skill does not request permanent inclusion or modify other skills. However model-invocation is enabled by default (agent may invoke autonomously); combined with the ability to run arbitrary repo scripts, that increases the potential blast radius if the agent is permitted to run this skill without explicit user confirmation.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install wells1137-skill-updater
  3. After installation, invoke the skill by name or use /wells1137-skill-updater
  4. Provide required inputs per the skill's parameter spec and get structured output
