Agentrix is a collection of deliberately focused tools. Start with a problem, choose a tool, and inspect the result. No unnecessary dashboards or accounts for the free CLI utilities.
All seven 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 |
|---|---|---|
| Flag sensitive filenames before a Git commit | Staged File Guard | Path-only staging check → |
| Check a JSONL / NDJSON file for malformed records | JSONL Guard | JSON Lines validator quick start → |
Catch missing or undocumented .env keys before deployment |
Env Contract | Dotenv checker quick start → |
| Audit CSV column counts, quoting and formula-like cells | CSV Guard | CSV validator quick start → |
| Compare JSON configuration or API response snapshots | JSON Diff | JSON comparison quick start → |
| Check UTM tags before publishing campaign links | UTM Audit | Campaign link checker quick start → |
| Map CSV columns and export valid rows in a browser | Data Import Studio | Load the sample dataset → |
With Git and Node.js 20+, run the six 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 14 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 seven 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-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.
A curated library of reusable instructions for common technical and creative tasks. All 15 are free to read and adapt, subject to applicable licenses and third-party terms.

Two complete editable SaaS landing pages: Atlas Analytics and Fieldnote CRM. Download and customize the HTML/CSS/JavaScript for personal or commercial websites with no checkout, login, password, or payment. These are frontend templates, not a working SaaS backend.

The kit is free to use for your own and client projects. Redistributing the unmodified pack as a competing template product is not permitted. This source-available license is separate from the MIT licenses of the seven free microtools.
No premium template is currently available to purchase. The SaaS Landing Kit has been released as a free product rather than a paid preview. This does not change the status of any other Agentrix product.
Premium products are separate, optional offers. Each product has its own scope, availability, and delivery details. A product described as a preview is not available for purchase.
Campaign QA Pro is a local browser-based tool for bulk campaign-link checks, CSV imports, configurable UTM naming allowlists, and downloadable QA reports. It does not replace or restrict the free UTM Audit CLI.

- Useful over complicated. Each tool targets a specific workflow.
- Honest by design. Read the limitations and inspect results before making decisions.
- Local first where practical. The free CLIs do not upload your files.
- Free stays free. The seven MIT microtools and 15 agent skills are not locked behind the premium checkout.
Revenue Reconcile compares expected receivables with settled receipts and flags missing payments, possible duplicates and amount/fee differences. Revenue Pulse audits recurring-revenue movements, churn and overdue invoice balances. Both are paid-first offline previews using fictional CSV datasets; they are not available for purchase. No bank connection or automated collection is included.
Agentrix is built around practical problems, reproducible examples, and useful feedback, not follower farming.
