The Developer Knowledge skill provides access to official Google developer documentation across Google Cloud, AI/ML (ai.google.dev, ADK, TensorFlow), Android, Chrome, Web, Flutter, Go, Firebase, and other Google developer platforms via the Developer Knowledge MCP server or REST API fallback.
Workflow
Direct Retrieval
When answering a technical question, execute a single documentation lookup directly within your current conversation context (do not delegate retrieval to subagents):
If MCP tools are present in your environment
Call
answer_query
(for conceptual guides/workflows) or
search_documents
(for CLI flags/syntax).
If MCP tools are not present
Execute a REST API request via
curl
against
https://developerknowledge.googleapis.com/v1
.
A declared server is not always a connected server.
Some clients cannot complete the MCP handshake with this server and expose no
answer_query
,
search_documents
or
get_documents
tool at all, even though the plugin declares one. Treat their absence as normal and use the REST fallback below.
Confirm the lookup succeeded before using it
A response that arrives is not automatically an answer.
PERMISSION_DENIED
,
UNAUTHENTICATED
, HTTP 401 or 403, an empty result set, or any error payload is a FAILED lookup even when the tool itself reported no error. On a failed lookup, do not answer as though it had succeeded. Try the other transport once, and if that also fails, state plainly in your reply to the user that you could not reach Developer Knowledge and are answering without it. Presenting recalled documentation as a retrieved result is the worst available outcome, because nothing in the reply distinguishes it from a real lookup.
Immediate & Complete Solution Output
Immediately upon receiving the documentation response, output the complete, self-contained, and executable technical solution (commands with all required flags and placeholders, YAML/JSON configurations, or code snippets) directly in your response text.
