build-mule-integration
Workflow required before any Mule flow and integration work. Call use_skill as your FIRST action — before reading project files — whenever the user asks to create, generate, update, fix, modify, change, edit, tweak, adjust, or rework any Mule flow, sub-flow, or component. Do not read project files and attempt the change yourself — even targeted single-component changes like 'modify the choice router', 'fix the until-successful', or 'update the catch block' require this workflow. Covers all change types, new integrations and targeted changes to error handlers, catch blocks, choice routers, DataWeave transforms, HTTP listeners, foreach loops, retry policies, scatter-gathers, connectors, and variable assignments. Prompts beginning with 'This code defines...' or 'This flow...' are generation requests, not analysis. When you call this skill, it must be the only tool call in that response.

Security
2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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: 0.90). The skill explicitly queries Anypoint Exchange and fetches live connector metadata (via scripts/get_latest_connector.sh and scripts/describe_connector.sh which call anypoint-cli dx mule describe-connector) and the workflow (SKILL.md Steps 3–5, 11–13) requires the agent to read and act on that returned, third‑party connector content to choose connectors, triggers, providers, and versions—meeting the conditions for untrusted third‑party input that can change tool use and next actions.
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
Potentially malicious external URL detected (high risk: 0.90). The skill's runtime scripts (e.g., get_latest_connector.sh and describe_connector.sh) query Anypoint Exchange at runtime and use the live connector metadata/GAVs from https://www.mulesoft.com/exchange/ to drive AskUserQuestion prompts, connector selection, and generated build artifacts, so the external Exchange content directly controls agent prompts and code generation.
