@@ -10,69 +10,12 @@ There are many ways that you can contribute:
 
 If you haven't already, join our slack workspace [here](https://docs.netbird.io/slack-url), we would love to discuss topics that need community contribution and enhancements to existing features.
 
-## Ticket first, PR second
-
-**Open a ticket and wait for feedback before you open a pull request.** Every PR
-that changes behavior must link to an issue the NetBird team has agreed on. A PR
-that arrives without one may be closed and redirected to a discussion, no matter
-how good the code is.
-
-Issues in this repository are maintainer-curated work items, so the flow starts
-in [Discussions](https://github.com/netbirdio/netbird/discussions):
-
-1. **Open a discussion.** Use
-   [Issue Triage](https://github.com/netbirdio/netbird/discussions/new?category=issue-triage)
-   for a bug, regression, or unexpected behavior, and
-   [Ideas & Feature Requests](https://github.com/netbirdio/netbird/discussions/new?category=ideas-feature-requests)
-   for a feature, enhancement, or integration idea. Setup and usage questions
-   belong in
-   [Q&A / Support](https://github.com/netbirdio/netbird/discussions/new?category=q-a-support).
-   Never report a security vulnerability in public — follow the
-   [security policy](https://github.com/netbirdio/netbird/security/policy)
-   instead.
-2. **Wait for feedback.** DevRel validates and reproduces the report, and a
-   maintainer confirms the direction. We may ask for more detail or propose a
-   different approach. Validated discussions become issues.
-3. **Then write the code**, following the approach agreed in the issue, and open
-   the PR linking that issue.
-
-Trivial fixes — a typo, a broken link, a documentation correction, or a one-line
-fix that already has an issue — can go straight to a PR. Everything else starts
-with a ticket. When in doubt, ask in the discussion or on
-[Slack](https://docs.netbird.io/slack-url); an hour of conversation up front
-regularly saves a week of rework.
-
-### High-risk areas
-
-These always need the design discussed and agreed in the issue **before** you
-write code:
-
-- **Public API** — REST / management API, OpenAPI schema, dashboard-facing contracts
-- **gRPC protocols** — management, signal, relay, and client daemon protos
-- **Functionality behavior** — anything existing deployments would experience differently after an upgrade
-- **Peer connectivity** — ICE and NAT traversal, relay selection, WireGuard® and Rosenpass key handling
-- **Client system integration** — routing, firewall, DNS, and interface management
-- **Authentication and authorization** — IdP integration, tokens, permissions, cryptography
-- **CLI / service flags**, configuration file format, and daemon IPC
-- **Store and database schema** — models and migrations
-- **New features**
-
-These surfaces are NetBird's contract with operators, self-hosters, and
-downstream integrators, and changes to them have compatibility, security, and
-release-planning implications. Agreeing on the direction early lets the PR
-review focus on implementation rather than design.
-
-Typical bug fixes, internal refactors, documentation updates, and tests do not
-need a design discussion, but should still be tied to an issue so the work is
-visible and nobody duplicates it.

+## Discuss changes with the NetBird team first
+
+Changes to the **public API**, **gRPC protocols**, **functionality behavior**, **CLI / service flags**, or **new features** should be discussed with the NetBird team before you start the work. These surfaces are part of NetBird's contract with operators, self-hosters, and downstream integrators, and changes to them have compatibility, security, and release-planning implications that benefit from an early conversation.
+
+Open an issue or reach out on [Slack](https://docs.netbird.io/slack-url) to talk through what you have in mind. We'll help shape the change, flag any constraints we know about, and confirm the direction so the PR review can focus on implementation rather than design.
+
+Typical bug fixes, internal refactors, documentation updates, and tests do not need pre-discussion — open the PR directly.

 ## Checklist before submitting a PR
-
-As a critical network service and open-source project, we must enforce a few
-things before submitting a pull request. The
-[pull request template](/.github/pull_request_template.md) mirrors this list —
-fill it in rather than deleting it.
-
-### Link the issue
-
-The PR description must link the agreed issue (or the validated discussion it
-came from). See [Ticket first, PR second](#ticket-first-pr-second).
-
-### Run it locally
-
-**If you can't run it, you can't submit it.** Build the affected components and
-exercise the change on a real setup — see [Build and start](#build-and-start).
-"CI will tell me" is not acceptable for a VPN agent that runs as root on other
-people's machines.
-
-### Green CI, and answer the bots
-
-We do not start reviewing while CI is red. Get the pipeline green first — a
-failing build, lint, or test means the PR is not ready for review.
-
-Alongside the test workflows, your PR is reviewed by CodeRabbit and scanned by
-SonarCloud, Snyk, and Codecov. Read what they report and either fix it or reply
-with why it does not apply; please do not resolve the threads without a
-response. They are not always right — this codebase has privileged,
-platform-specific, and concurrency-heavy paths that static analysis reads poorly
-— so push back when a finding is wrong rather than changing correct code to
-silence it. Security and dependency findings are the exception: treat those as
-real until shown otherwise. Do not edit workflows, thresholds, or scanner
-configuration to make a check pass.
-
-### One PR, one purpose
-
-Bug fix, refactor, feature: separate PRs. Mixed PRs are slow to review, hard to
-revert, and may be closed with a request to split them.
-
-### Keep it small
-
-Size is the strongest predictor of how long a PR waits for review. Aim for under
-roughly 400 changed lines across under 20 files. Past about 1000 lines or 50
-files, expect to be asked to split the change — and large PRs from outside the
-core team may be blocked until the scope has been agreed in a ticket. This is
-not only about reviewer time: NetBird's agent runs as root on other people's
-machines, and a sprawling diff cannot be reviewed with the care that deserves.
-
-Measure by hand-written code, excluding generated output, `go.sum`, and
-fixtures. If a change genuinely cannot be small — a protocol migration, a
-cross-component rename — agree the split in the issue before you start, and land
-it as a series of PRs that each build and make sense on their own.
-
-### Avoid force-pushing during review
-
-Once a PR is open, push new commits instead of rewriting history. A force-push
-detaches existing review comments from their lines, throws away the
-"changes since your last review" diff, and loses the CI history that showed
-which commit broke what. Since we squash on merge, there is nothing to gain from
-a tidy branch history.
-
-Force-pushing is sometimes unavoidable — rebasing to clear a real conflict, or
-removing a secret or large binary committed by mistake. When that happens, leave
-a comment on the PR so reviewers know their anchors moved.
-
-### Quality checks
-
-Run these from the repository root before pushing:
-
-```shell
-go fmt ./...
-make lint        # golangci-lint on files changed against origin/main
-make lint-all    # full-repository lint, matches CI
-make test-unit   # host-safe unit tests
-```
-
-`make setup-hooks` wires `make lint` into a pre-push hook so the fast lint runs
-automatically. If your change touches privileged paths (firewall, routing,
-interface management), also run `make test-privileged`, which executes the
-`privileged`-tagged suite inside a Docker container with `NET_ADMIN`.
-
-### Code standards
-
+As a critical network service and open-source project, we must enforce a few things before submitting the pull-requests:
 - Keep functions as simple as possible, with a single purpose
 - Use private functions and constants where possible
 - Comment on any new public functions
 - Add unit tests for any new public function
-- Comment the **why**, not the **what** — explain non-obvious decisions, invariants, and constraints, not the line below
-- Keep comments within 90 characters per line and roughly 250 characters per comment; when a block needs more explanation than that, extract a named function instead of writing a longer comment (see [AGENTS.md](AGENTS.md#length-budget))
-
-### PR title and commits
-
-PR titles must start with a bracketed tag, enforced by
-[pr-title-check.yml](/.github/workflows/pr-title-check.yml):
-
-```text
-[client] Authorize daemon IPC callers by their local identity
-[management,client] Add MDM policy support
-```
-
-Use a comma-separated list inside a single pair of brackets when a change spans
-components. The `allowedTags` array in
-[pr-title-check.yml](/.github/workflows/pr-title-check.yml) is the source of
-truth — at the time of writing it accepts `management`, `client`, `signal`,
-`proxy`, `relay`, `misc`, `infrastructure`, `self-hosted`, and `doc`.
-
-Commit subjects follow the same convention — keep them short and put the
-reasoning in the body, why before what, with no bullet list of files changed.
-
-Keep the PR description itself under 1000 words on top of the template text.
-Reviewers read the diff; the description explains what the diff cannot.
 
 > When pushing fixes to the PR comments, please push as separate commits; we will squash the PR before merging, so there is no need to squash it before pushing it, and we are more than okay with 10-100 commits in a single PR. This helps review the fixes to the requested changes.
 
-### Documentation
-
-User-facing changes need a matching PR in
-[netbirdio/docs](https://github.com/netbirdio/docs); link it in the PR
-description, or state why documentation is not needed.
-
-## When we close a PR
-
-We would rather redirect early than let a PR sit. We may close one if:
-
-- It changes behavior with no linked issue, or the approach was never agreed with a maintainer
-- The change was clearly never run or tested locally
-- CI has been red without a response
-- It mixes unrelated purposes, or the purpose is not clear
-- It is far too large to review and the scope was never agreed in a ticket
-- The author cannot answer questions about their own change — including PRs that read as unreviewed model output, where review turns into a relay between the maintainer and an LLM. Tooling is fine; unreviewed output is not, you are responsible for the code you sign your name to
-- There has been no activity for 14 days after we requested changes
-
-A closed PR is not a rejected idea. Take it back to the
-[discussion](https://github.com/netbirdio/netbird/discussions), settle the
-approach, and reopen the work from there.

-NetBird's goal is to provide a secure network. The client runs as a privileged service on every machine it is installed on,
-so we take reports about it seriously and we publish what we fix.
+NetBird's goal is to provide a secure network. If you find a vulnerability or bug, please report it by opening an issue [here](https://github.com/netbirdio/netbird/issues/new?assignees=&labels=&template=bug-issue-report.md&title=) or by contacting us by email.

+- We currently support only the latest version
 
 ## Reporting a Vulnerability
 
-**Please do not open a public issue for a security vulnerability.** Public issues are visible to everyone, including before
-a fix is available.
-
-Report security issues one of these two ways:
-
-- **GitHub private vulnerability reporting** — [open a private report](https://github.com/netbirdio/netbird/security/advisories/new)
-  on this repository. This is the preferred route: it keeps the discussion, the draft advisory, and the credit in one place.
-- **Email** — `security@netbird.io`.
-
-If the finding affects NetBird Cloud or our hosted infrastructure rather than the open-source code, email us rather than
-filing a repository report.
-
-### What to include
-
-A report is easier to act on when it contains:
-
-- The affected component (client, management, signal, relay, dashboard) and the version or commit you tested
-- The platform and configuration, where relevant — operating system, self-hosted or NetBird Cloud, container or host install
-- What an attacker needs before they can exploit it: network position, an account, local access, a specific privilege level
-- Steps to reproduce, and a proof of concept if you have one
-- The impact you believe it has
-
-Partial reports are still welcome. If you are unsure whether something is a security issue, send it to `security@netbird.io`
-and let us make that call.
-
-## What to expect from us
-
-- **We acknowledge your report** and tell you whether we can reproduce it.
-- **We work with you on severity and scope.** If we assess it differently than you do, we will explain why rather than
-  silently downgrade it.
-- **We fix and release**, then publish a [GitHub Security Advisory](https://github.com/netbirdio/netbird/security/advisories)
-  naming the affected version range and the patched version.
-- **We credit reporters who want to be credited.** Tell us the name or handle you would like used, or that you would rather
-  stay anonymous.
-- **We keep you in the loop** until the advisory is published.
-
-We ask that you give us a reasonable opportunity to ship a fix before disclosing the issue publicly, and that you avoid
-accessing, modifying, or exfiltrating data belonging to other people while testing. Testing against your own installation
-or your own account is always fine.
-
-## Supported Versions
-
-We support the latest release. Security fixes ship in the next version rather than as backports to older releases, so
-upgrading to the current release is how you get them.
-
-Release notifications are available by watching [releases](https://github.com/netbirdio/netbird/releases).
-
-## Published advisories
-
-Every vulnerability we fix is published as a GitHub Security Advisory on the
-[advisories page](https://github.com/netbirdio/netbird/security/advisories), including the affected version range, the
-patched version, and the reporter's credit. Advisories for the Go module are also distributed through the Go vulnerability
-database, so `govulncheck` will report them against your dependencies.
-
-## Bug bounty
-
-There is no official bug bounty program for the NetBird project. We credit reporters in advisories, and we are grateful for
-the work, but we cannot currently offer payment for reports.

-# NetBird Agent Network
-
-Agent Network is NetBird's access control layer for AI agents and the people who run them. 
-It gives every agent a real identity, tied to an identity provider (IdP), and governs what it can reach: LLM APIs and 
-AI gateways it can call, and the internal resources it can access. Traffic flows only over the encrypted NetBird tunnel, 
-scoped by policy, with no API keys or other credentials to leak. It also gives you control over cost and token usage.
-
-Because every LLM request passes through an
-identity-aware proxy, you can:
-
-- **Set spending and rate limits** per agent, per user, or per team — with hard caps
-  that stop requests once a budget is reached.
-- **Restrict models and providers** so agents can only call approved (and cost-appropriate)
-  endpoints, keeping expensive models off-limits unless explicitly allowed.
-- **Attribute usage** by tracking token consumption and cost per identity, group, or cost center so every
-  request is tied back to the agent and person responsible.
-- **Reuse your existing AI gateway** — point the proxy at a gateway you already run,
-  keeping its routing and config in place while it adds identity on top, so you skip
-  API key distribution.
-
-https://github.com/user-attachments/assets/44d18286-d8ab-49f8-a457-98ccd66f3268
-
-> **Beta.** Agent Network is in beta, but it's stable and already running in
-> production environments. It's fully open source and can be self-hosted on your own
-> infrastructure, with no vendor lock-in and no data leaving your environment.
-
-## How it works
-
-Say you have a simple use case: your Engineering or IT team needs access to Claude Code or Codex, and you want visibility into usage plus the ability to enforce budgets.
-How can you do that without creating a dedicated API key for every team?
-
-With Agent Network you get a private endpoint inside your network, for example: https://mirror.netbird.ai
-Teams configure their agents to point to that endpoint instead of using individual API keys directly. 
-
-This endpoint is only reachable when users are connected to your NetBird network and authenticated through your IdP. Otherwise, it is not accessible from the public internet.
-You can then use this private endpoint to configure your AI agents, whether that is Claude Code, Codex, or another tool.
-
-## Quickstart
-
-Full step-by-step setup:
-**https://docs.netbird.io/agent-network/quickstart**
-
-## Architecture 
-
-Agent Network is built on two existing NetBird capabilities:
-
-- **Overlay network** — the encrypted WireGuard mesh between peers.
-- **Reverse proxy** — a NetBird peer that terminates LLM requests, establishes the
-  caller's identity, evaluates policies/limits/guardrails, injects the upstream provider
-  key server-side, forwards to the API or gateway, and records usage.
-
-LLM traffic is routed through the proxy's identity-aware pipeline, while internal
-resources (databases, internal APIs, self-hosted models) are reached directly over
-peer-to-peer WireGuard tunnels, governed by the same identities and access policies.

-
-
-## Where the code lives
-
-There is no separate "agent-network" service — it reuses the reverse-proxy and management
-components:
-
-- [`proxy/`](../proxy) — the NetBird reverse proxy that serves the agent network endpoint
-  and runs the per-request middleware pipeline.
-- [`management/internals/modules/reverseproxy/`](../management/internals/modules/reverseproxy)
-  — the management-side control plane: providers, policies, guardrails, limits, routing,
-  and usage/access logs.
