Usage Guidance
This skill appears coherent and lightweight: it builds Picsum URLs and can optionally download images. Before installing or using it, note: (1) it will make network requests to picsum.photos (no credentials required); (2) if you ask it to download, it will write files to a path you specify (default ./tmp/) — verify the path and file size; (3) the SKILL.md mentions optional Python helper scripts, but none are bundled here, so the agent won't be able to run them unless you provide them or Python is available; (4) the skill correctly warns not to execute downloaded content — follow that. If you need downloads disabled, prefer URL-only responses. If you want verification that no extra tools will be executed, request explicit confirmation in the agent's next response before any download occurs.
Capability Analysis
Type: OpenClaw Skill
Name: random-image-placeholder
Version: 0.1.1
The skill is designed to generate and optionally download placeholder image URLs using the legitimate service https://picsum.photos. The instructions in SKILL.md are well-defined, include explicit security constraints (e.g., 'never execute downloaded files'), and do not contain any evidence of prompt injection, data exfiltration, or unauthorized execution.
Capability Assessment
Purpose & Capability
Name/description match what the SKILL.md instructs: generate Picsum URLs and optionally download images. The skill does not request unrelated credentials, binaries, or config paths. One minor mismatch: the instructions reference optional helper scripts (scripts/picsum.py and references/picsum-api.md) and Python usage, but the package contains no code files and the registry metadata does not declare Python as a required binary.
Instruction Scope
SKILL.md stays within the stated purpose: building URLs, optionally downloading images to a user-specified path (default ./tmp/), and verifying file existence. It explicitly warns not to execute downloaded content. Note: the instructions allow reading optional local helper files if present; since no code files are bundled, the agent should not assume those helpers exist. Downloading writes files to disk — acceptable for the stated goal but users should expect file I/O.
Install Mechanism
Instruction-only skill with no install spec and no bundled code to write to disk. This is the lowest-risk install model.
Credentials
No environment variables, secrets, or primary credentials are requested. The skill's actions (network requests to picsum.photos and optional file writes) are proportional to the stated purpose.
Persistence & Privilege
always is false and the skill does not request persistent system presence or modify other skills' configurations. It can be invoked autonomously by the agent (platform default), which is appropriate for a simple utility.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install random-image-placeholder - After installation, invoke the skill by name or use
/random-image-placeholder - Provide required inputs per the skill's parameter spec and get structured output
Version History
v0.1.1
- No functional code changes; documentation clarified and workflow updated.
- Now emphasizes generating URLs directly via Picsum patterns, rather than always using local scripts.
- Rules updated: don’t write files unless download is specifically requested; clarify default output path and explicit user intent.
- Clarifies that references and helpers are optional if present.
- Streamlined workflow and instructions for both URL and download usages.
