Eric Wagoner 4bf7481f9b Extract reports unidentifiable boxes for human retakes
The vision prompt now returns {titles, unidentified}: boxes that look
like games but can't be confidently titled are reported (location
relative to identified neighbors, partial text, art notes) instead of
silently omitted. They land in data/unidentified.json keyed by photo,
and the end-of-run summary lists them — plus low-confidence reads —
with instructions to retake a closer photo and re-run. New --force flag
re-extracts everything; pre-feature raw caches (bare arrays) still
parse. Live run on IMG_4499 confirmed the flow and the low-confidence
list correctly flags the known "Hebarceos" misread.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project

bggpipe — a resumable, idempotent CLI pipeline: shelf photos → Claude vision title + edition-cue extraction → BoardGameGeek ID and version matching → human review → collection diff → upload to BGG via Playwright → metadata enrichment (games.json). Full design: @bgg-shelf-pipeline-spec.md. The repo is greenfield — no code exists yet. Follow the spec's "Suggested Build Order" when scaffolding; re-run /init once code exists.

Stack (decided, not yet scaffolded)

  • Python 3.12+, deps via uv (uv add, uv run), CLI framework typer, tests pytest, lint/format ruff.
  • Browser automation: Playwright (not Selenium). Needs uv run playwright install chromium after install.
  • Vision: Anthropic API, latest Sonnet model.

Hard rules (from spec — never violate)

  • ≤1 request every 2 seconds to any BGG endpoint; jittered backoff on 429/503. Upload stage: 24 s randomized delay between games.
  • Credentials never touch disk or logs. ANTHROPIC_API_KEY, BGG_USERNAME, BGG_PASSWORD, BGG_API_TOKEN come from env vars only. Playwright storage state is credential-adjacent — keep it gitignored.
  • The XML API requires a registered app token (Authorization: Bearer, from BGG_API_TOKEN) — unregistered requests get 401. Until Eric's registration at boardgamegeek.com/applications is approved, tests run on the stub fixtures in tests/fixtures/bgg_cache/; re-record them with scripts/record_fixtures.py once the token exists.
  • Every stage is idempotent and resumable — killing mid-run and restarting must lose no work; re-runs skip already-processed items.
  • Use only the XML API2 and the public website — no undocumented BGG endpoints (BGG tightened access policies in 2025).
  • BGG has no write API: writes drive the real website with a logged-in Playwright session.

Domain gotchas

  • Base game vs. expansion vs. new edition is the top failure mode — bias matching toward ambiguous over auto-match ("Wingspan Europe" must not match base Wingspan).
  • Editions/versions matter: Eric owns multiple editions of some games — each is a separate collection entry (keyed by collid on BGG). Never guess a version: no legible cues → version_unknown and a version-less collection entry.
  • Normalize titles (casefold, strip punctuation/articles, special chars like é/&/:) identically on both sides of a match; dedupe across photos but keep source_photos provenance.
  • Detailed BGG API behavior (202 queueing, collection-endpoint quirks, endpoints): use the bgg-api skill. If the spec's BGG behavior changes, update the bgg-api skill to match — they must not drift.

Git

  • Remote is self-hosted Gitea 1.26 (git.kestrelsnest.social), not GitHubgh CLI does not work here.
  • Commit data/matches.csv, data/to_add.csv, data/upload_log.csv, data/titles.json, data/unidentified.json, data/games.json. Never commit data/bgg_cache/, photos/, Playwright storage state, or .env.
