* ♻️ Take the command limits before the root ones in the RPC limiter The RPC concurrency limiter took the root limiters (the ones every request passes through) before the ones a command declares, so a request waiting for the limits of its own command held the root permits of its profile while it waited: a profile with a pile-up of heavy requests saw its other requests queue behind them and be rejected with 429. That order was forced by two commands that entered the limiter from inside their handler: a command that declares no limits of its own can only take them deeper than the root ones, so two paths of one profile could take the same limiters in opposite order and park for good. The commands declare their limits in their metadata now and their handlers call the work directly, so no command enters the limiter from inside its handler and every path takes the limiters in the same order. The root limiters are appended to the sequence first, so the limits a command declares end up outermost and are taken first: a request waiting for them does not hold the root permits of its profile. The photo of a team keeps its limits, because it declares them now that the helper does not. A call from inside a handler can only reenter the limits that thread already holds, and it is refused when it asks for a new one, because that would take it after the root ones and invert the order against the other paths. The key of a limit is resolved the same way in every path, so both paths point at the same limiter and the reentrancy check sees it. Every entry of the shipped climit.edn declares a queue, so the number of requests waiting for the same limit is bounded instead of piling up until the timeout. The production file lives outside the repository and has to be mirrored to pick them up. The tests cover the acquisition order of a command with and without limits of its own, the order of the limits as a whole (a ring of any size fails, not only a pair in opposite order), the nested call that asks for a limit the thread does not hold, and the queues and timeouts of the shipped configuration. The import of a binfile declares its request as multipart in its test, the way the commands that take an upload map do.

Both commands declare the by-profile limit alone now, and the example config drops the entry. A declared id without an entry does not limit anything: `wrap` logs a warning and runs the handler with no limiter at all, which is how a command ends up unbounded in production. A test fails now when a command declares an id the config does not list, and the header of the example says the production file mirrors the shape and lists every declared id, not the values.

The rule says to keep working on something else, or to end the response and wait for it. AI-assisted-by: minimax-m3.1-flash

Penpot is the open-source design platform for teams that build digital products at scale.
Penpot’s key strength lies in giving you full ownership of your design infrastructure. Built on open source and designed for self-hosting, it puts teams in complete control of their design environment supporting strict compliance and governance requirements. Whether used in the browser or deployed on your own servers, Penpot works with open standards like SVG, CSS, HTML, and JSON.
Real-time collaboration strengthens this foundation, helping teams scale and bring design closer to the product through top-tier capabilities. Additionally, developers feel at home using Penpot, because design is expressed as code, enabling a direct translation and shipping products faster.
Best-in-class native Design Tokens provide a single source of truth between design and development. They ensure consistency, improve collaboration, and make it easier to manage complex design systems.
The MCP server takes it further by enabling multi-directional workflows between design and code. A powerful open API and plugin system makes the workspace programmable, enabling automation, AI-driven workflows, and integrations with the tools and systems you already use.
With CSS Grid and Flex Layout, teams can design responsive interfaces that behave like real code from the start.
Combined, these features turn Penpot into a full-stack design platform for building scalable design systems and fully integrated product development processes.
If your organization is scaling and needs extra support, we’re here to help. Talk to us

Why Penpot
Penpot connects design, code, and AI workflows through a code-based approach, making designs readable by developers and AI via the MCP server. This approach helps teams ship what’s actually designed and manage design systems at scale with powerful design tokens. As a self-hosted, open-source and real-time collaboration platform, Penpot offers full flexibility, security, and ownership without vendor lock-in. Learn more about why Penpot is the platform for your team.
Plugin system
Penpot plugins let you expand the platform's capabilities, give you the flexibility to integrate it with other apps, and design custom solutions.
Designed for developers
Penpot was built to serve both designers and developers and create a fluid design-code process. You have the choice to enjoy real-time collaboration or play "solo".
Inspect mode
Work with ready-to-use code and make your workflow easy and fast. The inspect tab gives instant access to SVG, CSS and HTML code.
Integrations
Penpot offers integration into the development toolchain, thanks to its support for webhooks and an API accessible through access tokens.
Building Design Systems: design tokens, components and variants
Penpot brings design systems to code-minded teams: a single source of truth with native Design Tokens, Components, and Variants for scalable, reusable, and consistent UI across projects and platforms.
Getting started
Penpot is the only design & prototype platform that is deployment agnostic. You can use it in our SAAS or deploy it anywhere.
Learn how to install it with Docker, Kubernetes, Elestio or other options on our website.
Penpot Enterprise
Penpot Enterprise is our paid plan for organizations that need to scale their design work across multiple teams with advanced governance, security, and administration. Manage teams and access from a centralized Admin Console, configure advanced permissions, and connect your identity provider through SSO. Available for cloud and self-hosted environments, it combines enterprise controls with Penpot’s open-source foundation and open standards.
