fix: readme

[elkaix]

Add npm i command to top Install block.

[greptile-apps]

Greptile Summary

Adds an npm installation command to the primary README installation section before the Claude MCP registration command.

The documented install path was exercised in an isolated npm project: the public package installed successfully, exposed its declared executable, and completed an MCP initialization exchange through the documented npx command. No product defects were found.

T-Rex validation blocked

The completed execution logs and scripts were uploaded without the required artifact labels. Because the evidence references cannot be rendered with compliant labels, they are not included as publishable proof artifacts.

Confidence Score: 5/5

Safe to merge: the README-only installation guidance matches a working public npm package and MCP startup path.

No review findings remain after exercising the exact npm installation command and the accompanying npx MCP initialization flow.

Files Needing Attention: None. README.md was the only changed file, and its new installation instructions were exercised successfully.

T-Rex Logs

What T-Rex did

• The documented npm i @pymodel/claude-agy-mcp and npx -y @pymodel/claude-agy-mcp were run in an isolated temporary npm project to initialize the MCP flow.
• A baseline pre-install log was inspected to confirm there were no installed packages, establishing the comparison baseline.
• An after-validation log was produced showing the documented npm command, metadata inspection, and MCP initialization completed successfully.
• Baseline and validation shell scripts were identified and cataloged to support reproducibility of the contract test.
