These four official Marketplace templates cover developer and product work, from wrapping an API as a plugin to auditing a codebase overnight. Several of them can touch repositories, so this guide puts access checks next to each one.
Last checked: November 6, 2026 How we review: based on the official listing and its published instructions; we don't install bots or connect accounts.
tinkabot
What it does: wraps an API into a Cursor or Agent plugin (MCP server plus skills). It names the data shape first, builds the smallest working scaffold, proves it locally, then asks once about affiliation and publishes to Cursor Marketplace or cursor.directory.
Who it is for: developers and API owners who want a plugin without hand-building the scaffold.
Integrations: the listing names a pstack plugin and shows an integrations section, but no full list or scopes.
Routines: none shown on the public listing.
Safety: tinkabot writes plugin code and can submit to plugin marketplaces; its instructions say it never publishes without your explicit word and an approval gate blocks submission, so check publishing access in the Add preview and review files before approving.
Setup time: not given in the listing.

Nightly Audit Engineer
What it does: researches a whole codebase, then ships one cleanup pull request per area, favoring small diffs and root-cause fixes.
Who it is for: engineering leads with cleanup debt and the capacity to review small PRs.
Integrations: not listed publicly; shipping PRs implies repository access, so check the preview.
Routines: a nightly run that defaults to 4am and asks when to run before it starts.
Safety: Nightly Audit Engineer reads your codebase and opens pull requests on a schedule; check which repositories and write permissions the Add preview requests, and keep branch protection and human review on every PR.
Setup time: not given in the listing.

Proto Bot
What it does: turns daily ideas into prototypes in your real app as draft pull requests with click-path screenshots and a short video, plus Figma mocks and images.
Who it is for: founders, product managers, and designers who want to see ideas running before committing engineering time.
Integrations: instructions mention cloud agents, Figma, and your own FAL, Higgsfield, or xAI keys for media; the full list and scopes are not published.
Routines: a routines section is shown, but the listing does not describe them.
Safety: Proto Bot can work in your repository, open draft PRs, and spend on your media keys; its instructions say it never merges, deploys, publishes, or shares without your yes, so check repository and Figma access, routines, and the spend cap in the Add preview.
Setup time: not given in the listing.

Product Idea Stress Test
What it does: investigates a product or startup idea and surfaces what has to be true, evidence for and against, the assumption most likely to kill it, and what to test next.
Who it is for: founders and builders deciding whether an idea deserves more time before prototyping.
Integrations: none shown on the public listing.
Routines: none shown on the public listing.
Safety: Product Idea Stress Test works on the ideas and files you share; check the Add preview for any requested access and share only details you are comfortable storing.
Setup time: not given in the listing.

How to add a developer template
- Open the official Marketplace listing and check the creator and job description.
- Choose Add on a Marketplace card, Import Bot on a template page, or Add to Grok Bot as the official guide calls it.
- Review the preview: memories, skills, routines, and integrations. Confirm repository access is limited to what the job needs.
- Select Add Bot. You get a separate copy, not a clone of the creator's environment.
- Reinstall any plugins your copy needs; they may not carry over ready to run.
- Start with one repository or one small task, and keep branch protection on before enabling any routine.
Build your own
Pick one repeatable engineering task with a clear output, such as a draft PR or a written report. List the repositories it needs, decide which actions must wait for approval, and keep merge and deploy rights with people. Test on a small repository before sharing the template with a team.
FAQ
Which developer templates can change my code?
Nightly Audit Engineer opens cleanup pull requests and Proto Bot builds draft pull requests. tinkabot writes plugin code and can publish after your approval. Product Idea Stress Test does not work in code.
Do these templates merge or deploy for me?
Proto Bot's instructions say it never merges, deploys, or pushes to a default branch without your yes. The Nightly Audit Engineer listing does not publish merge rules, so keep branch protection and manual merges on.
How long does setup take?
None of the four official listings gives a setup time.
