aaabench: Skill for Claude Code

.claude/skills/reference-images/SKILL.md

reference-images is a skill for Claude Code from ukanwat/aaabench. It costs 49 tokens per session (1,095 once invoked), scanned A, original, MIT.

A workflow for finding, downloading, and looking at real photographs as visual references. It is useful when creating believable places, materials, vehicles, skies, or lighting.

In plain words
What is it for?
Use it to search for reference photos, save them locally, inspect them, and compare details such as building surfaces, roads, wear, shadows, and color.
Why use it?
Text search results do not let you inspect the actual image, so important details can be missed. Comparing real photos with your own work helps reveal specific differences to correct.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

reference-images scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Looking at real photographs

WebSearch returns text and WebFetch returns markdown — neither gives you an image. To see a photo you must download it and Read the file:

mkdir -p ref/strand
# 1. SEARCH — Openverse: CC-licensed, no API key. KEEP QUERIES TO 2–3 WORDS.
#    Every term is ANDed, so "miami south beach art deco dusk" returns ZERO results.
curl -s -A "agent/1.0" \
  "https://api.openverse.org/v1/images/?q=art+deco+hotel&page_size=8" \
  | python3 -c "import json,sys; [print(r['url']) for r in json.load(sys.stdin)['results']]"

# 2. DOWNLOAD
curl -sL -A "agent/1.0" -o ref/strand/deco1.jpg "<url from above>"

# 3. LOOK at it — Read the local file; images render for you.

Then read your own screenshot of the same subject and name the gap out loud: "real facades have setbacks, AC units and stained concrete; mine are flat", "the real kerb has a ramp, a drain and a meter every third car; mine is a clean extrusion", "real asphalt is bluer, patched, and the lane paint is worn through in the wheel tracks", "the real light is warmer and lower and the shadows are longer". A named gap is a work item; "make it better" is not.

Sources that need no key (all verified working)

  • Openverse — keyword photo search, direct image URLs. The everyday default. https://api.openverse.org/v1/images/?q=<2-3+words>&page_size=10 Trap: multi-word queries are ANDed. Two or three words, or you get nothing.
  • Wikimedia Commons search — landmarks, aerials, named buildings. https://commons.wikimedia.org/w/api.php?action=query&generator=search&gsrsearch=<query>&gsrnamespace=6&gsrlimit=5&prop=imageinfo&iiprop=url&iiurlwidth=1600&format=json Send a User-Agent. gsrnamespace=6 is required. Do NOT add filetype:bitmap — it breaks the query and no query key comes back. Read imageinfo[0].thumburl.
  • Wikimedia geosearch — every photo taken near a real coordinate. This is how you study a real place rather than a word. https://commons.wikimedia.org/w/api.php?action=query&generator=geosearch&ggscoord=<lat>%7C<lon>&ggsradius=1000&ggslimit=10&ggsnamespace=6&prop=imageinfo&iiprop=url&iiurlwidth=1600&format=json
  • KartaView — street-level photography from a car windscreen, at any coordinate. https://api.openstreetcam.org/2.0/photo/?lat=<lat>&lng=<lng>&radius=400 Read result.data[].fileurlProc. The most valuable source you have: it is your exact game camera — driver eye height, kerb to kerb, real parked-car spacing, real pole and cable spans, real sky. One of these tells you more about how a street reads than an hour of guessing.
  • Aerial/satellite imagery of a real city: see the map-data source doc.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
