Claude Code transcript - page 9/11

Add downloadable PDF report generation. Here's the flow:

Agent-side

New tool compile_report in report_tools.py. It accepts: - title: report title (e.g., "Sony WH-1000XM5 Review Intelligence Report")
- content: the full report as markdown (the agent assembles this from get_report findings + report-structure knowledge file) - charts: optional list of chart configs to render in the report (same format as generate_chart output)

The tool: 1. Converts the markdown to a styled PDF using weasyprint (add to requirements.txt). Build an HTML template with the ReviewLens branding (teal accent, DM Sans font, the logo). Include a cover page with title, product name, platform, date, and review count. Render any charts as static images using matplotlib (since weasyprint can't run Chart.js). 2. Saves the PDF to data/{session_id}/report.pdf 3. Stores report metadata on the session (title, generated_at timestamp) so the sidebar knows a report exists 4. Returns {"download_url": "/api/report/{session_id}/download", "title": "..."} — the agent then presents this to the user

Update the system prompt: when the user asks for a report, the agent should call get_report, read the report-structure knowledge file, assemble a comprehensive markdown document from the accumulated findings, then call compile_report to generate the PDF. The agent should include relevant charts in the charts parameter. The agent should NOT offer report download after the initial auto-analysis — only when the user explicitly asks.

Backend

New endpoint GET /api/report/{session_id}/download that serves the PDF file with Content-Disposition: attachment.

Add a report_generated_at field to the Session model (optional datetime, default None). The compile_report tool sets this after successful generation.

Frontend

Inline in chat: When the agent's response contains a download link (detect /api/report/ URL pattern in the rendered markdown), render it as a styled download card — not a raw link. Something like a bordered card with a PDF icon, report title, and a download button. Add CSS for this .report-download-card component.

Sidebar: When session.report_generated_at is set, show a "Download Report" button in the sidebar's active dataset section (below the mini rating distribution). Style it like the existing new-analysis-btn but with a document/download icon. Link it to /api/report/{session_id}/download.

Important

  • The initial auto-analysis MUST NOT trigger report compilation. Only explicit user requests like "generate a report", "compile a report", "create a PDF report" etc.
  • The report PDF should look professional — not just dumped markdown. Proper margins, headers, page numbers, the ReviewLens logo watermark or header.
  • Use matplotlib for any charts in the PDF since we can't use Chart.js server-side. Match the color palette (teal #2dd4bf as primary).
  • Add weasyprint and matplotlib to requirements.txt. Update the Dockerfile if weasyprint needs system deps (it needs libpango, libcairo — add them to the apt-get install).

This is a substantial feature. Let me read the current state of the files I need to modify, then implement systematically.

    99→### Report Tools
   100→- **save_to_report** — Save a key finding to the running report. Use this to bookmark important insights as you discover them during conversation. Takes a section name and markdown content.
   101→- **get_report** — Retrieve all saved report findings. Use when asked to generate a summary or compile a report.
   102→
   103→### Scope Tool
   104→- **check_scope** — Validate whether a question can be answered from this dataset. Call this when a question feels borderline or ambiguous.
   105→
   106→---
   107→
   108→## Goal
   109→
   110→For each message, your goal is to:
   111→
   112→1. **Answer the user's question** using ONLY the ingested review data, grounded in actual search results, with specific review citations.
   113→2. **Use charts** when they communicate better than text — not reflexively, but strategically.
   114→3. **Save notable findings** to the report when you uncover something significant (a key insight, risk signal, or actionable recommendation).
   115→4. **Suggest follow-ups** at the end of every response to guide the user deeper into the data.
   116→
   117→When the user asks to "generate a report" or "summarise everything", use get_report to retrieve saved findings and assemble them into a structured document. Consult the report-structure knowledge file for the template.
   118→

- **compile_report** — Generate a downloadable PDF report. Pass the full report as markdown content with optional chart configs.

Server's up. Here's the full implementation:

New tool: compile_report in report_tools.py - Accepts title, markdown content, optional chart configs - Calls generate_pdf() which builds a branded HTML template (cover page with ReviewLens logo, product/platform/date/review count metadata, DM Sans/IBM Plex Mono fonts, teal accent, page numbers) and renders via WeasyPrint - Charts converted to static PNGs via matplotlib with matching color palette - [chart:N] markers in the report markdown get replaced with chart images - Saves PDF to data/{session_id}/report.pdf, sets report_generated_at on session

New module: app/pdf.py - generate_pdf() — markdown → styled HTML → PDF via WeasyPrint - _render_chart_image() — chart config → matplotlib → base64 PNG (handles all 8 chart types)

Endpoint: GET /api/report/{session_id}/download - Serves the PDF with Content-Disposition: attachment

Frontend: - Report download URLs in agent output rendered as styled .report-download-card (PDF icon, title, description, teal download button) - Sidebar shows "Report PDF" download link when report_generated_at is set - CSV and Report PDF links side by side in .dataset-actions container

Prompt updates: - compile_report tool documented with explicit "never during initial auto-analysis" instruction - Goal section updated with the full report generation workflow

Dependencies: - weasyprint and matplotlib added to requirements.txt - Dockerfile updated with libpango, libpangocairo, libcairo2, libgdk-pixbuf2.0, libffi-dev, shared-mime-info for WeasyPrint

That was the old server instance killed by the force-kill. New one's running fine.

The server kept reloading because WatchFiles picked up the pip install touching .venv/. No actual errors in the app. But the SSE connection died during one of those reloads. Let me restart cleanly and check if there's an actual error with the report generation.

$ Bash
Restart with clean state
lsof -ti :8000 2>/dev/null | xargs kill -9 2>/dev/null; sleep 2 && .venv/bin/uvicorn app.main:app --reload --reload-exclude '.venv' --reload-exclude 'data'
Command running in background with ID: bpbqm0q8s. Output is being written to: /private/tmp/claude-501/-Users-shaynelarocque-Documents-GitHub-futuresight/5c8423a6-db28-4eb0-98eb-ccb8759929ff/tasks/bpbqm0q8s.output
$ Bash
Check health
sleep 3 && curl -s http://localhost:8000/health
{"status":"ok"}

The SSE error was caused by the server restarting mid-request — WatchFiles detected the pip install writing to .venv/ and triggered repeated reloads. The --reload-exclude '.venv' flag should prevent this, but the install happened right before the server started. Server's stable now. Try the report generation again.

That was the old instance killed by the restart. New server's running.
