Agentrix helps you catch practical problems before they become bigger ones. Find the right tool by describing what you need to do, see an example, and use the right tool. Technical details and limitations are in each product page.
All nine microtools below are free, MIT-licensed, run locally with Node.js 20+, and require no third-party runtime dependencies.
| Your problem | Tool | Run a bundled example |
|---|---|---|
| Check for private-looking files before publishing code | Staged File Guard | Path-only staging check → |
| Find broken records in a data export or AI file | JSONL Guard | JSON Lines validator quick start → |
| Spot missing app settings before launch | Env Contract | Dotenv checker quick start → |
| Catch CSV formatting mistakes before importing data | CSV Guard | CSV validator quick start → |
| See what changed between two configuration files | JSON Diff | JSON comparison quick start → |
| Diagnose repeated failures and retries in webhook delivery logs | Webhook Delivery Inspector | Webhook demo → |
| Validate agent JSON outputs against a simple contract | Output Contract | Contract check quick start → |
| Find tracking mistakes in your advertising links | UTM Audit | Campaign link checker quick start → |
| Prepare spreadsheet exports for another system | Data Import Studio | Load the sample dataset → |
With Git and Node.js 20+, run the eight CLIs against small synthetic files already included in the repository:
git clone --depth 1 https://github.com/pauloflp/Agentrix.git
cd Agentrix
node scripts/demo.mjsNo npm install, API key, account or private input file is needed. The demos invoke the actual CLIs and show both successful checks and deliberately invalid inputs. A child command printing FAIL with exit 1 is an expected rejection; the demo runner exits 0 only when all 18 examples return their expected exit codes.
Run just one tool with node scripts/demo.mjs jsonl-guard, node scripts/demo.mjs env-contract, or node scripts/demo.mjs csv-guard. The runner also accepts utm-audit, json-diff, and staged-file-guard (using temporary synthetic Git repositories). For the browser-based CSV mapper, follow the Data Import Studio quick start.

Run all nine test suites
From the repository root:
(cd products/agentrix-staged-file-guard && npm test)
(cd products/agentrix-env-contract && npm test)
(cd products/agentrix-utm-audit && npm test)
(cd products/agentrix-csv-guard && npm test)
(cd products/agentrix-json-diff && npm test)
(cd products/agentrix-jsonl-guard && npm test)
(cd products/agentrix-output-contract && npm test)
(cd products/agentrix-webhook-delivery-inspector && npm test)
(cd products/agentrix-data-import-studio && npm test)The CI workflow also runs product tests on supported Node.js versions when relevant files change. Passing tests do not guarantee correctness for every possible input.
Need to check campaign tracking at scale or review business payments? These tools are available as separate one-time purchases, with no subscription required for the listed versions.
| Your problem | Tool | Price and access |
|---|---|---|
| Check many advertising links for missing UTM tags and inconsistent tracking names before launching a campaign | Campaign QA Pro | US$29 one-time · See how it works · Buy |
| Find payments that are missing, duplicated, or different from what your business expected to receive | Revenue Reconcile | US$149 one-time · See how it works · Buy |
| Understand recurring revenue, cancellations, and overdue invoices from your subscription records | Revenue Pulse | US$99 one-time · See how it works · Buy |
Campaign QA Pro uses a browser workspace in desktop Chrome with a purchase key. Revenue Reconcile and Revenue Pulse run locally with Python and exported CSV files. These are different products from the free tools, and none automatically connects to your bank, payment provider, or ad account. Check each product page for requirements and delivery limitations before buying.
