Build apps with the Claude API or Anthropic SDK. TRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`/`claude_agent_sdk`, or user asks to use Claude API, Anthropic SDKs, or Agent SDK. DO NOT TRIGGER when: code imports `openai`/other AI SDK, general programming, or ML/data-science tasks.

Critical

E004: Prompt injection detected in skill instructions.

What this means

Detected a prompt injection in the skill instructions. The skill contains hidden or deceptive instructions that fall outside its stated purpose and attempt to override the agent’s safety guidelines or intended behavior.

Why it was flagged

The content includes explicit, authoritative directives (e.g., "ALWAYS use claude-opus-4-6" / "This is non-negotiable") and documents options to bypass permission prompts (e.g., "bypassPermissions" with allow_dangerously_skip_permissions), which weakens security/user consent boundaries and constitutes suspicious steering without clear malicious intent.

Low

Low-risk findings.

2 low severity findings. Worth noting, but not necessarily harmful.

Low

W011: Third-party content exposure detected (indirect prompt injection risk).

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

In the required runtime workflow, the agent is driven by a caller-provided `prompt` string passed into `claude_agent_sdk.query()` (and subsequent agent turns/messages), which is outsider-authored free text and is directly ingested by the LLM.

Low

W012: Unverifiable external dependency detected (runtime URL that controls agent).

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

The skill explicitly calls out using WebFetch at runtime to pull live documentation (e.g., https://platform.claude.com/docs/en/about-claude/models/overview.md) and lists many WebFetch/raw-GitHub URLs whose fetched content would be injected/extracted to drive prompts, so these URLs are runtime dependencies that can directly control agent prompts.
