Description
Optimize web performance and LLM API costs. Covers loading speed, runtime efficiency, resource optimization, and cost-aware LLM pipelines with model routing,...
Usage Guidance
This skill is instruction-only and its content matches its stated goal, but an automated scan found possible prompt-injection/system-prompt-override patterns. Before installing: 1) Open and grep the entire SKILL.md for phrases like 'ignore previous', 'system:', 'You are', 'override', or explicit instructions to change the agent's system prompt — remove/ask the author about any such lines. 2) Do not provide API keys, tokens, or other secrets to the agent just to enable this skill; if you must, use scoped/test keys. 3) Run the skill in a sandboxed/test agent first and observe what network calls or system interactions it suggests. 4) If you lack the ability to audit the full SKILL.md, treat the skill as untrusted. If you want, share the full SKILL.md contents for a line-by-line check focused on prompt-injection indicators.
Capability Analysis
Type: OpenClaw Skill
Name: performance-ecc
Version: 2.0.0
The skill bundle provides standard documentation and code snippets for web performance and LLM cost optimization. It covers best practices such as resource preloading, image optimization, and API budget tracking (SKILL.md) without any evidence of malicious intent, data exfiltration, or prompt injection.
Capability Assessment
Purpose & Capability
The name/description (web performance + LLM cost optimization) match the SKILL.md content: guidance, examples, and model-routing concepts appear relevant. There are no declared binaries, env vars, or config paths that are unrelated to the stated purpose.
Instruction Scope
Most of the runtime instructions are focused on web performance best practices (rendering path, image/font optimization, caching, JS patterns) and some LLM cost concepts. However, the pre-scan flagged a potential 'system-prompt-override' pattern in the SKILL.md frontmatter/content. The visible excerpts do not show explicit exfiltration or credential access, but any lines that attempt to override the agent's system prompt, tell the model to ignore other instructions, or instruct broad data collection would be out-of-scope and should be inspected and removed.
Install Mechanism
Instruction-only skill with no install spec and no code files. This is the lowest installation risk (nothing is written to disk by an installer).
Credentials
The skill declares no required environment variables, credentials, or config paths. That is proportionate to an instruction-only guidance skill. Note: because it discusses LLM routing and cost, an agent using this skill might be instructed to call LLM APIs — do not provide API keys or tokens to the agent unless you intend it to make those calls and the keys are scoped/limited.
Persistence & Privilege
always:false and no requests to modify other skill or system configs. The skill does not request persistent presence or elevated privileges from the manifest.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install performance-ecc - After installation, invoke the skill by name or use
/performance-ecc - Provide required inputs per the skill's parameter spec and get structured output
