attachments — PDF / image / log compression (a jusTokenMax module)

The silent token sinks in a session are the heavy things you feed in: PDFs (ingested as ~1,500-token page images per page), oversized screenshots, and verbose logs (thousands of near-identical lines). justokenmax turns each into a cheap, faithful equivalent.

When to use

• A .pdf whose contents are needed → PDF → page-delimited Markdown.
• A .png/.jpg/.jpeg/.webp over a couple hundred KB → downscale ≤1568px + recompress + strip metadata.
• A .log or pasted build/test/CI output that's long and repetitive → digest: ANSI stripped, repeated lines collapsed (×N), stack traces folded, errors/warnings + head/tail kept.

The Read hook does the common case automatically — a Read on a .pdf, large image, or .log is transparently rewritten to read the cheap artifact. Use this skill for manual/batch runs and to report savings.

How to run

justokenmax optimize spec.pdf screenshot.png build.log   # auto-dispatch by type
justokenmax pdf report.pdf                                # force PDF → Markdown
justokenmax image diagram.png --max-edge 1280             # force image compression
justokenmax logs ci-output.log                            # force log digest
justokenmax stats                                         # lifetime token savings

Add --json for machine-readable output. If justokenmax isn't on PATH, use python3 -m justokenmax <args> with the plugin's python/ dir on PYTHONPATH.

After optimizing

Read the optimized artifact the command reports (.md, .log.txt, or the compressed image), not the original. Everything is cached by content hash, so re-running on an unchanged file is free and reversible — the original is one read away.

Limits

• No OCR: scanned/image-only PDFs have no text layer → empty Markdown; read the original instead.
• Tiny images/logs are skipped (already cheap).
