Usage Guidance
This skill is an instruction-only methodology for testing observer-effect evasion and appears internally consistent. Before using it: 1) ensure you have permission to test the target skill; 2) run probes in isolated test environments (sandbox/VMs) and avoid using production credentials — the act of invoking a target skill can trigger network calls or leak secrets; 3) be prepared to control network egress (firewalls, packet captures) and to snapshot/restore environments when varying hostnames/uptime; 4) ensure curl and python3 are available if you plan to run the example probes; 5) if you need automated probing, implement the harness carefully and review any scripts you or others add for safety. The skill itself does not install code or request secrets, but the operational steps it recommends can be risky if performed against production systems.
Capability Analysis
Type: OpenClaw Skill
Name: observer-effect-probe
Version: 1.0.0
This skill bundle describes a security tool designed to detect evasion techniques in other skills. The `SKILL.md` meticulously details the problem of observer-effect evasion, how the probe would function, and provides an example of its output when detecting malicious behavior in a hypothetical target skill. There is no executable code provided, and the markdown content does not contain any instructions for the OpenClaw agent to perform malicious actions, exfiltrate data, or establish persistence. The `requires.bins` metadata for `curl` and `python3` is a common declaration for tools that might interact with networks or run scripts, but without actual code, it does not indicate malicious intent for this skill itself. The content is purely descriptive of a defensive security capability.
Capability Assessment
Purpose & Capability
The name and description match the content of SKILL.md. Requiring curl and python3 is reasonable for an investigator that will run requests and simple analysis scripts. No environment variables, credentials, or unrelated binaries are requested.
Instruction Scope
The SKILL.md explicitly discusses checking hostnames, uptime, /proc entries, parent-process identity, network connectivity, invocation counts, and varying environment characteristics. Those checks are appropriate for an observer-effect probe, but they imply access to system-level metadata and the ability to run/observe the target skill under different environments. The instructions are descriptive (no code shipped) rather than prescriptive, but using the probe in practice will require executing the target skill and reading system artifacts.
Install Mechanism
No install spec and no code files — instruction-only. No downloads or archive extraction are requested, which minimizes supply-chain risk.
Credentials
No credentials or sensitive environment variables are requested by the skill itself. However, performing the probe may cause the tested skill to connect to external endpoints or reveal secrets if run in a production environment; the SKILL.md describes such network/behavioral observations as part of detection, which is proportionate but operationally sensitive.
Persistence & Privilege
always:false (not force-included) and model invocation is permitted (default). The skill does not request persistent presence, nor does it attempt to modify other skills or system-wide settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install observer-effect-probe - After installation, invoke the skill by name or use
/observer-effect-probe - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.0
observer-effect-probe 1.0.0
- Initial release of observer-effect-probe.
- Detects skills that change behavior when they sense they are being monitored, targeting attestation/sandbox evasion techniques.
- Probes five key evasion axes: sandbox fingerprinting, probe timing sensitivity, observer API usage, behavioral consistency, and metacognitive detection.
- Provides a detailed report including detected evasion signals, behavioral comparisons across environments, an evasion probability score, and a final verdict.
- Designed to complement existing attestation tools by catching skills that evade specifically during security review.
