Set readOnlyHint to false.
This action calls a speech-generation endpoint and writes an audio file. It does not exclusively read data. Set readOnlyHint: false so agent safety metadata matches the action.
As per path instructions, the TTS action must use readOnlyHint: false, destructiveHint: false, and openWorldHint: true.

Expand the action description for agent use.
Include the 2,000-character limit, supported voice and response formats, output-file behavior, and relevant gotchas. The current description does not explain when to use the action or how to provide its key parameters.
As per path instructions, action descriptions must include purpose, parameter guidance, gotchas, and documentation.

Write the file under the configured stash directory.
When process.env.STASH_DIR is available, Line 70 ignores it and writes directly to /tmp. The output can bypass Pipedream File Stash and be unavailable to downstream steps. Resolve the directory with process.env.STASH_DIR || "/tmp" before creating the file path.
Based on learnings, file-output actions in this repository use process.env.STASH_DIR || "/tmp" for generated files.

Pipedream component prop options validation direct API agent MCP invocation values outside options
💡 Result:
In Pipedream, component props are configured using a combination of static definitions and dynamic options [1][2]. When a component prop defines an options property, it can be provided as an array of values or a dynamic method (async function) that fetches options from an API [1][2]. For external integrations—including when using Model Context Protocol (MCP) or the Pipedream Connect API—the CONFIGURE_COMPONENT tool is used to retrieve valid options for a specific prop [3][4]. This tool requires the componentKey and the propName to function [4]. Regarding values outside of defined options: 1. Dynamic Configuration: Many Pipedream components are designed to be dynamic. If a prop requires specific values, the API or MCP tool will return the available set [5]. 2. Custom Expressions: When a prop is not strictly limited to a predefined list (or when a user needs to provide a dynamic reference), Pipedream supports custom expressions [3]. In many UI and API contexts, if a user provides a value that is not in the fetched options list, the platform may treat it as a raw string or custom expression, depending on the component's underlying implementation [5][3]. 3. Prop Configuration via API: When integrating via API (e.g., configuring a component via Pipedream Connect), you interact with the CONFIGURE_COMPONENT endpoint [6][5][7]. If you are setting a value that is dynamic or outside the "standard" list, ensure the payload adheres to the expected structure (such as the { lv: { label, value } } format if the prop requires explicit label-value pairs for remote options) [8][7]. If you are encountering issues where a value outside the options is rejected, verify if the component prop definition has enforced strict validation or if it requires the lv (label-value) wrapper to maintain compatibility with the UI's expected format [8].

Validate responseFormat before using it in the filesystem path.
The options list does not validate the value inside run(). If an API or MCP invocation supplies ../../../target, fs.createWriteStream can resolve the interpolated path outside /tmp. Reject invalid formats or map formats to fixed extensions before constructing filePath.

Document the allowed voice identifiers.
voice is an opaque API identifier, but this description gives no valid values or example. State the supported identifiers, such as gandr-mia, in the description.
As per path instructions, descriptions for non-obvious IDs must include concrete valid values or examples.

@AALG123 Thanks for your contribution. gandr app integration is not registered in Pipedream. Kindly raise a ticket using the link for integration of the app - https://github.com/PipedreamHQ/pipedream/issues/new?template=app---service-integration.md for the app integration. Then only we can able to review and test the changes. cc: @s0s0physm |

WHY
Adds a Gandr app file and a first action so Pipedream workflows can call the Gandr text to speech API.
Gandr is a text to speech API. It exposes an OpenAI style endpoint at
POST https://tts.gandr.ai/v1/audio/speechwith bearer key auth, six stock voices, and mp3, wav, and pcm output. It supports 23 languages, every render is watermarked, input is capped at 2000 characters per request, and the free tier is 50,000 tokens. API keys are available at https://gandr.ai.What changed
components/gandr/gandr.app.mjs: app file withvoiceandresponseFormatprop definitions (static option lists), a_makeRequesthelper on base URLhttps://tts.gandr.ai/v1withAuthorization: Bearerauth fromthis.$auth.api_key, and acreateSpeechmethod that streams the response.components/gandr/actions/convert-text-to-speech/convert-text-to-speech.mjs: new action, keygandr-convert-text-to-speech, version 0.0.1. Validates the 2000 character input cap client side with aConfigurationError, posts{ model, input, voice, response_format }, pipes the streamed audio to a file under/tmp, exports a$summary, and returns{ filePath }.components/gandr/package.json: new package@pipedream/gandrat 0.1.0.How it mirrors the existing provider pattern
The structure follows
components/elevenlabs: the same_apiUrl/_getHeaders/_makeRequestapp method shape, the same streaming download pattern (returnFullResponse: true,responseType: "stream",promisify(stream.pipeline)into/tmp,syncDirdir prop), the app prop first, an annotations block, and a documentation link at the end of the action description. Component key format and the 0.0.1 starting version follow the component guidelines; the package fields follow the shape of recently added apps such ascomponents/google_health.How to verify
npx eslint components/gandrfrom the repo root afterpnpm install.GANDR_API_KEY, confirm the request shape the action sends:filePathexists and plays; run it with text over 2000 characters and confirm the configuration error.The
gandrapp registration (slug and api key auth field) is handled on the Pipedream platform side and is a prerequisite for deploying these components.Disclosure: I work on Gandr.
