From 0b79aff222f904b81c383ea8e7c66a997d1e8f5a Mon Sep 17 00:00:00 2001 From: Claudiu Farcas Date: Sun, 21 Jun 2026 21:22:08 +0300 Subject: [PATCH] Enhance portfolio review tool with explicit path requirement and summary JSON output - Update report file resolution to require an explicit path by default, with an option for auto-detection. - Implement a summary JSON output for agent inspection, excluding free-text fields and providing key metrics. - Modify documentation and tests to reflect these changes. --- README.md | 32 +++--- skills/xtb-portfolio-review/SKILL.md | 12 ++- skills/xtb-portfolio-review/scripts/main.py | 110 +++++++++++++++++--- test_portfolio.py | 76 ++++++++++++++ 4 files changed, 199 insertions(+), 31 deletions(-) diff --git a/README.md b/README.md index 9599e32..4889c20 100644 --- a/README.md +++ b/README.md @@ -101,14 +101,15 @@ python3 -m venv .venv ``` Outputs are written to `results/`, including -`results/_review.html` for the portfolio review and +`results/_review.html` and `results/_summary.json` for the portfolio review and `results/_wealthfolio.csv` for the Wealthfolio import file.
