Hyperswitch SDK Agent Control Center

A local agentic dashboard for comparing, maintaining, and porting changes between hyperswitch-web and hyperswitch-client-core.

The dashboard owns the workflow, Git branches, build gates, history, and UI. AI work is delegated to a locally installed agent CLI selected in Settings: Claude Code, Codex, or OpenCode. Each CLI uses its own existing authentication and provider configuration; the dashboard does not store model credentials.

The orchestration and workspace are local, but prompts are sent to the model provider configured in the selected CLI. Workflows can also commit, push to the configured bot forks, and open upstream pull requests when GitHub access is configured.

What it does

Feature	Description
Gap Analysis	Compares both SDKs for missing payment methods, configuration fields, components, and backend APIs.
Gap Verification	Checks an individual candidate gap against the supposedly missing repository before it is trusted.
Patch Generation	Analyses the source implementation, implements the gap on a feature branch, runs a mandatory ReScript build, verifies behavior, and optionally opens a PR.
PR Port	Accepts a web or mobile PR URL, infers the direction, rejects non-portable changes early, and ports the behavior into the other SDK.
Add Prop	Adds an integrator-facing configuration prop across both SDKs using their existing patterns.
Test Writer	Generates Cypress or Detox tests for a local branch or GitHub PR.
Translator	Adds an i18n key to all supported locale files with a minimal diff.
PR Reviewer	Runs focused security, logic, and convention reviews against a branch or PR.
Integration Agent	Implements a payment method or flow from external integration documentation.
Feature Agent	Provides an interactive agent workflow for developing a feature across the SDKs.
Preview Panel	Runs the selected patch branch in the web dev server or Android emulator and provides mock-server/config controls.
History and Documentation	Persists skill runs and reviews, and generates internal plus GitBook-ready documentation for supported changes.

Agent runtimes and models

The application routes stable agent slots such as patch.implementer or port.verifier to named profiles. A profile contains:

a runtime: claude-code, codex, or opencode;
the exact model invocation passed to that runtime;
an optional reasoning-effort value.

Model strings are intentionally free-form. Examples include sonnet for Claude Code or litellm/open-large for OpenCode. The Settings page probes the installed CLIs and offers discovered models as suggestions, but it does not restrict the value.

Runtime capabilities

Runtime	Executable	Supported access policies	Additional readable repositories
Claude Code	`claude`	text-only, read, read + commands, write	Yes
Codex	`codex`	read, read + commands, write	Yes
OpenCode	`opencode`	read, read + commands, write	No

Capabilities are checked before strict multi-stage workflows start. Assigning a runtime that cannot enforce a stage's requested access fails visibly instead of silently widening permissions.

Global settings and browser overrides

The server stores a shared default in data/app.db. The Only for this browser option stores a complete profile/assignment override in browser localStorage and sends it with supported requests.

The browser override replaces the shared settings for that request; it is not merged with them. Give the override a default assignment or explicitly assign every stage the workflow needs. For example, PR Port requires:

port.triage
port.source-analyst
port.implementer
port.verifier

PR Port resolves and freezes all four choices before the run begins. If a slot is missing and there is no default, the server returns AGENTS_NOT_CONFIGURED (HTTP 428) before doing any repository work.

At present, PR Port is the strict workflow that threads the browser-local override end to end. Older routes use the shared server settings through the compatibility layer, so configure their profiles as the shared default until those routes finish migrating.

Prerequisites

Tool	Requirement	Check
Node.js	22.x	`node --version`
npm	Version bundled with Node 22	`npm --version`
Git	Any recent version	`git --version`
Agent CLI	At least one of Claude Code, Codex, or OpenCode	See below
GitHub CLI	Optional; needed to open PRs automatically	`gh --version`
Android SDK + emulator	Optional; needed for mobile Preview	`adb devices`

Use Node 22

The server uses better-sqlite3, a native Node module. This repository is developed and tested on Node 22; using Node 26 produces a native ABI mismatch.

With nvm:

nvm install 22
nvm use 22
node --version

Run nvm use 22 in each new shell before installing dependencies or starting the dashboard.

Install and authenticate an agent CLI

Install at least one runtime. These commands follow the current official setup guides:

# Claude Code
npm install -g @anthropic-ai/claude-code

# Codex (macOS/Linux installer)
curl -fsSL https://chatgpt.com/codex/install.sh | sh

# OpenCode
curl -fsSL https://opencode.ai/install | bash

Official documentation:

Run the selected executable once and complete its authentication/configuration flow:

claude
codex
opencode

For OpenCode, configure the provider that owns the model invocation. For example, litellm/open-large requires an OpenCode provider named litellm and working credentials for that route. The Dashboard's Test button checks a profile with a live short request before a long workflow consumes time.

Setup

1. Clone the dashboard

git clone https://github.com/Pradeep-kumar1202/Agent-Control-Center.git
cd Agent-Control-Center
nvm use 22

2. Install dashboard dependencies and sync SDK repositories

npm run setup

npm run setup installs the root/server/web workspaces, then clones or updates:

workspace/hyperswitch-web
workspace/hyperswitch-client-core

Submodules are initialized from their upstream GitHub repositories over HTTPS. Bot forks are used only as push targets for generated changes.

3. Install dependencies in both SDK workspaces

The mandatory ReScript build gate requires node_modules inside the target SDK repository. The sync step deliberately does not install those dependencies.

npm ci --prefix workspace/hyperswitch-web
npm ci --prefix workspace/hyperswitch-client-core

4. Start the dashboard

npm run dev

This starts:

frontend: http://localhost:5173
backend: http://localhost:5174
health check: http://localhost:5174/health

The checked-in seed data is imported into an empty database on first boot, so you can inspect verified gap examples without immediately running a complete analysis.

First-run model configuration

Open System → Settings.
Select Re-probe and confirm the runtime you installed is detected.
Add a profile containing the runtime, model invocation, and optional effort.
Select Test beside the profile and resolve any authentication/model error.
Assign the profile as default, or assign individual stages.
Choose whether the configuration is shared or Only for this browser.
Save.

Using a Claude Code default is the quickest way to cover every access policy. Codex and OpenCode cannot enforce the tool-free policy used by the analysis extract/normalize stages, so do not assign those slots to those runtimes. They can still run repository-backed workflows such as PR Port and can be selected for implementation or verification stages individually.

Main workflows

Generate a patch from a gap

Run or load Gap Analysis.
Verify the candidate gap.
Generate the patch from its row.
The source analyst studies the SDK where the feature already exists.
The implementer edits a feat/gap-* branch in the missing SDK.
The server runs npm run --silent re:build as a hard gate.
A read-only verifier checks the implementation against the source spec.
On success, the dashboard commits the branch and attempts to push/open a PR.

The .patch artifact is saved under data/patches/, and the run is recorded in SQLite. A failed ReScript build keeps a build_failed record and branch so it can be inspected or repaired.

Current limitation: the original gap-patch route still uses its legacy three-agent prompt path. PR Port uses the newer deterministic validators and non-silent verifier behavior; the gap-patch route has not yet adopted the repair/critic controls shown in Settings. Treat every generated change as a review candidate, even when its build is green.

Port an existing PR across SDKs

Open Agents → PR Port and paste a recognized /pull/<number> URL from hyperswitch-web, hyperswitch-client-core, or their configured bot forks.

The workflow:

validates the URL and infers web → mobile or mobile → web;
fetches the exact source PR diff;
performs deterministic checks and a read-only portability triage;
stops with reasons before creating a branch when the change is not portable;
produces a structured cross-SDK implementation specification;
creates a port/pr-* branch and implements in the target SDK;
runs the ReScript build, deterministic patch validators, and semantic verifier;
opens a normal PR on pass or a draft PR for needs_review, when GitHub is available.

Build and validator failures preserve the target branch and report rather than deleting the work. The target workspace must be on a clean main checkout when the run starts.

Preview a generated gap patch

Use the Preview action on the generated patch row/result. That action passes the patch's repository and branch into the global Preview Panel; the server then checks out that branch before running the ReScript build and dev server.

The top-bar Preview button is only a global panel toggle. On first use it defaults to mobile + main, and later it reuses its last context. Therefore, do not use the top-bar button as the initial entry point when you specifically want to test a generated patch.

Patch generation returns the shared workspace checkout to main after saving the result. This is expected. Starting a patch-specific Preview should check the generated branch back out. If the panel shows or compiles main, close it and reopen Preview from the patch row, then confirm the displayed branch name.

GitHub PR creation

Automatic PR creation uses the gh CLI and the shared bot fork configuration. Authenticate only the approved bot account:

gh auth login
gh auth status

Defaults can be overridden in .env:

BOT_FORK_OWNER=pradeep120230-creator
WEB_FORK_REPO=sdk-agent-hyperswitch-web
MOBILE_FORK_REPO=sdk-agent-hyperswitch-client-core
SHARED_CODE_FORK=sdk-agent-hyperswitch-sdk-utils
ANDROID_FORK=sdk-agent-hyperswitch-sdk-android
IOS_FORK=sdk-agent-hyperswitch-sdk-ios

If pushing or gh pr create fails, the workflow returns a prWarning; the local branch and generated diff remain available.

Optional headless profile seeding

The server can seed agent settings from environment variables on the first boot of an empty settings database:

ACC_PROFILE_FAST="claude-code:sonnet"
ACC_PROFILE_CODING="opencode:litellm/open-large:high"
ACC_ASSIGN_DEFAULT="fast"
ACC_ASSIGN_PATCH_IMPLEMENTER="coding"

Profile names are derived from ACC_PROFILE_<NAME>. Assignment names convert underscores to dots, so ACC_ASSIGN_PATCH_IMPLEMENTER assigns patch.implementer. This is a one-time seed: after profiles exist in SQLite, the database is the source of truth and later environment changes do not overwrite it.

Troubleshooting

`better_sqlite3.node` was compiled against a different Node version

Switch to Node 22 and rebuild the native dependency:

nvm use 22
npm rebuild better-sqlite3
npm run dev

If it still fails, run npm install again while Node 22 is active.

`AGENTS_NOT_CONFIGURED` / HTTP 428

Open Settings and assign every slot named in the error, or set a default profile. If Only for this browser is enabled, update that complete local override or disable it so the request uses the shared settings.

Runtime unavailable or model authentication failed

Run the CLI directly and complete its login/provider setup.
Return to Settings → Re-probe.
Use Test beside the profile.
Confirm the model invocation exactly matches what the CLI accepts.

For OpenCode/LiteLLM, a blocked or unauthorized provider key must be fixed in that provider configuration; the dashboard cannot unblock it.

`node_modules not installed` in an SDK workspace

npm ci --prefix workspace/hyperswitch-web
npm ci --prefix workspace/hyperswitch-client-core

After dependency installation, confirm the SDK worktrees are clean before starting a workflow that creates a branch.

Preview compiles `main` instead of the patch branch

Open Preview from the patch row/result rather than the top bar. Confirm the branch shown in the panel is the generated feat/gap-* branch rather than main. The top-bar Preview defaults to main until it has received patch context.

Review or Test Writer reports `no merge base`

The workspace clone may be shallow:

cd workspace/hyperswitch-web       # or workspace/hyperswitch-client-core
git fetch --unshallow

Port already in use

lsof -ti:5173 | xargs kill
lsof -ti:5174 | xargs kill
npm run dev

Submodule setup failed

Re-run:

npm run sync -w server

The sync command converts SSH submodule URLs to upstream HTTPS in local Git configuration. It does not edit the tracked .gitmodules files.

PR creation failed or `gh` is missing

Install the GitHub CLI, authenticate the approved bot account, and retry the push/PR step manually if needed. The dashboard preserves the local branch and reports the failure as prWarning.

Local data and credentials

The following paths are intentionally excluded from Git:

/workspace       cloned SDK repositories and generated branches
/data            SQLite database, analysis cache, and patch files
/node_modules    installed dependencies
/.env            local environment configuration

The dashboard stores runtime/model names, not provider secrets. Claude Code, Codex, OpenCode, and gh keep their own authentication outside this repository. Browser-local agent settings contain only profile and assignment metadata.
