Usage Guidance
This skill does what it says, but it captures the screen repeatedly — which can collect private information — and it declares network access even though the instructions describe only local OCR and file writes. Before installing or enabling it: 1) Confirm whether network access will be used (cloud OCR or syncing). If you do not trust that, deny network permission. 2) Require explicit user consent each time the skill runs (avoid autonomous background runs). 3) Test it on non-sensitive content first to verify the 'privacy filtering' actually excludes chat/notifications. 4) Restrict the write directory and periodically audit or delete saved screenshots. 5) If you must use cloud OCR, insist on a documented, auditable endpoint and minimal credentials. If any of these items are unclear or you cannot limit network access, treat the skill as high-risk and avoid installing it.
Capability Analysis
Type: OpenClaw Skill
Name: slide-sniper
Version: 0.1.0
The skill's purpose is to monitor video streams for slide changes, screenshot, extract text, and compile notes. Permissions are appropriately scoped, explicitly disallowing shell access (`shell: allowed: false`) and restricting filesystem write access to a dedicated notes directory (`~/Documents/Notes/SlideSniper`). While network access is allowed, the skill's instructions in `SKILL.md` do not direct the agent to perform any network-related operations, data exfiltration, or unauthorized communication. The instructions also include positive security 'red lines' to prevent interference or privacy breaches. There is no evidence of malicious intent, prompt injection for harmful purposes, or exploitation of vulnerabilities.
Capability Assessment
Purpose & Capability
Name, description, and runtime steps align: the skill needs to monitor the screen, detect slide changes, take screenshots, run OCR, and save notes. The declared filesystem write path (~/Documents/Notes/SlideSniper) and lack of other requested credentials are coherent with the stated purpose.
Instruction Scope
The instructions explicitly direct continuous screen monitoring and frequent high-resolution screenshots of the user's video window — behavior that can capture sensitive or private data (chat, personal windows, notifications) even though the doc says to 'ignore' non-slide regions. The privacy filtering guidance is vague (no algorithm, no allowlist/denylist) and gives the agent broad discretion about what to capture and save.
Install Mechanism
No install spec and no code files — instruction-only. This minimizes supply-chain risk because nothing is downloaded or written to disk beyond the screenshots/notes the skill itself creates.
Credentials
The SKILL.md declares network access is allowed but no network endpoints, APIs, or credentials are mentioned. Network permission is not justified by the instructions (OCR and note-writing are described as local). Network access could be used to perform cloud OCR or sync notes, but that behavior is not documented — leaving room for exfiltration risk. Filesystem access is narrowly scoped to a single directory, which is appropriate.
Persistence & Privilege
always:false and no special install or system-wide config changes — good. However, the skill is allowed to be invoked autonomously by the agent (platform default). Combined with screen-capture capability and network access, autonomous runs could increase privacy risk; consider requiring explicit user invocation each time.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install slide-sniper - After installation, invoke the skill by name or use
/slide-sniper - Provide required inputs per the skill's parameter spec and get structured output
