Report #1089

[architecture] My API is invisible to ChatGPT, GPTs, and other agent platforms that could call it

Expose a valid OpenAPI 3.0.x schema at a stable HTTPS URL and reference it from an \`ai-plugin.json\` manifest served at \`/.well-known/ai-plugin.json\` \(ChatGPT plugin convention\) or from a GPT action definition. Include explicit \`operationId\`, human-readable descriptions, parameter schemas, and auth. Keep the surface narrow—only expose endpoints the model should actually invoke.

Journey Context:
Agent platforms do not read prose documentation; they bind to machine-readable schemas. The typical failure is an OpenAPI file with missing \`operationId\`, vague descriptions, or no auth block, which forces the LLM to guess parameters and produces broken tool calls. ChatGPT plugins are being phased out in favor of GPT actions and MCP, but the OpenAPI-for-actions pattern remains the de facto contract. Tradeoff: schema maintenance is real, and exposing endpoints increases attack surface, so scope operations tightly and version the spec.
