DELETE-method operations are excluded unless +`includeDestructive` is true, and are always tagged destructive. + +Bindings are user-scoped, non-secret values-store config (`_openapi:`). +Credentials stay in secrets / integrations. + +At runtime the capability registry synthesizes an `openapi:` domain per +binding.

Package jobs are owned by packages, ad hoc jobs can be scheduled with \`job_schedule\`, and package apps are optional package surfaces. - Official how-to guides from the Kody repo: when creating or materially changing a package, call \`coding_guide_get\` with \`guide: "package_authoring"\`. If the package, package app, or workflow depends on a third-party integration, secrets, or OAuth, call \`guide: "integration_bootstrap"\` before building the dependent package. If unsure, \`search\` for this capability and load the right guide before implementing. - Do not save or present an auth-dependent package as complete until \`search\` shows the required integration or secret reference exists and a minimal authenticated \`execute\` smoke test succeeds. diff --git a/packages/worker/src/mcp/tools/search-format.node.test.ts b/packages/worker/src/mcp/tools/search-format.node.test.ts index 99fe903eb4..25c870fd72 100644 --- a/packages/worker/src/mcp/tools/search-format.node.test.ts +++ b/packages/worker/src/mcp/tools/search-format.node.test.ts @@ -399,6 +399,75 @@ test('capability formatting keeps execute contracts for identifier and bracket i args: { owner: 'o', repo: 'r', title: 't' }, }, ]) + + const openApiDetail = formatEntityDetailMarkdown({ + type: 'capability', + id: 'openapi:widgets:listwidgets', + title: 'openapi:widgets:listwidgets', + description: 'List widgets — GET /widgets', + spec: { + name: 'openapi:widgets:listwidgets', + domain: 'openapi:widgets', + description: 'List widgets — GET /widgets', + keywords: [], + readOnly: true, + idempotent: false, + destructive: false, + source: 'openapi', + openApi: { + bindingName: 'widgets', + kodyName: 'widgets', + operationSlug: 'listwidgets', + method: 'get', + path: '/widgets', + }, + inputFields: ['query'], + requiredInputFields: [], + outputFields: [], + inputSchema: { type: 'object', properties: {} }, + inputTypeDefinition: + 'type OpenapiWidgetsListwidgetsInput = Record', + }, + }) + expect(openApiDetail.markdown).toContain( + 'kody.openapi["widgets"].listwidgets(input)', + ) + expect(openApiDetail.structured).toMatchObject({ + source: 'openapi', + openApi: { + kodyName: 'widgets', + operationSlug: 'listwidgets', + }, + executeExample: expect.stringContaining( + 'kody.openapi["widgets"].listwidgets(input)', + ), + }) + const [openApiMatch] = toSlimStructuredMatches({ + baseUrl: 'http://localhost', + matches: [ + { + type: 'capability', + name: 'openapi:widgets:listwidgets', + description: 'List widgets — GET /widgets', + source: 'openapi', + openApi: { + bindingName: 'widgets', + kodyName: 'widgets', + operationSlug: 'listwidgets', + method: 'get', + path: '/widgets', + }, + }, + ], + }) + expect(openApiMatch).toMatchObject({ + type: 'capability', + usage: 'execute with kody.openapi["widgets"].listwidgets(args)', + openApi: { + kodyName: 'widgets', + operationSlug: 'listwidgets', + }, + }) }) test('package entity detail includes exports, jobs, and referenced local types', () => { diff --git a/packages/worker/src/mcp/tools/search-format.ts b/packages/worker/src/mcp/tools/search-format.ts index 48d6fef3be..c26ceef515 100644 --- a/packages/worker/src/mcp/tools/search-format.ts +++ b/packages/worker/src/mcp/tools/search-format.ts @@ -113,6 +113,7 @@ export type SlimSearchMatch = source?: CapabilitySpec['source'] remoteConnector?: CapabilitySpec['remoteConnector'] mcpServer?: CapabilitySpec['mcpServer'] + openApi?: CapabilitySpec['openApi'] } | { type: 'package' @@ -218,6 +219,7 @@ export type SearchEntityDetailStructured = source: CapabilitySpec['source'] remoteConnector?: CapabilitySpec['remoteConnector'] mcpServer?: CapabilitySpec['mcpServer'] + openApi?: CapabilitySpec['openApi'] inputTypeDefinition: string outputTypeDefinition?: string } @@ -381,6 +383,7 @@ export type SearchMatch = source?: CapabilitySpec['source'] remoteConnector?: CapabilitySpec['remoteConnector'] mcpServer?: CapabilitySpec['mcpServer'] + openApi?: CapabilitySpec['openApi'] } | { type: 'package' @@ -447,6 +450,7 @@ function buildCapabilityUsage(spec: { source?: CapabilitySpec['source'] remoteConnector?: CapabilitySpec['remoteConnector'] mcpServer?: CapabilitySpec['mcpServer'] + openApi?: CapabilitySpec['openApi'] }) { return `execute with ${buildKodyCapabilityAccessor(spec)}(args)` } @@ -468,6 +472,7 @@ function buildKodyCapabilityAccessor(spec: { source?: CapabilitySpec['source'] remoteConnector?: CapabilitySpec['remoteConnector'] mcpServer?: CapabilitySpec['mcpServer'] + openApi?: CapabilitySpec['openApi'] }) { if (spec.source === 'remote-connector' && spec.remoteConnector) { return buildNamespacedKodyAccessor({ @@ -483,6 +488,13 @@ function buildKodyCapabilityAccessor(spec: { toolName: spec.mcpServer.toolName, }) } + if (spec.source === 'openapi' && spec.openApi) { + return buildNamespacedKodyAccessor({ + namespace: 'openapi', + entryName: spec.openApi.kodyName, + toolName: spec.openApi.operationSlug, + }) + } const { name } = spec if (/^[A-Za-z_$][\w$]*$/.test(name)) { return `kody.${name}` @@ -693,6 +705,7 @@ export function toSlimStructuredMatches(input: { ?
