High

W007: Insecure credential handling detected in skill instructions

What this means

The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.

Why it was flagged

Insecure credential handling detected (high risk: 1.00). This prompt requires the agent to take raw download URLs and other MCP-returned content (including prototype HTML with image src URLs) and embed them verbatim into curl commands, saved files, and task descriptions — which can expose signed download URLs or other sensitive tokens directly in agent outputs/context.

Medium

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

Third-party content exposure detected (high risk: 0.95). The skill ingests outsider-authored free text from a user-supplied Miro board/item URL at runtime via the Miro MCP item-retrieval tools (documents/diagrams/frames/tables/other) and prototype screen HTML (which may include arbitrary text and image URLs), then writes that content into `.miro/specs/*` and updates `index.json`.

Medium

W021: Hidden or invisible Unicode characters detected (potential obfuscation or prompt injection)

Why it was flagged

Hidden Unicode characters detected (1 type(s) found)
