Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.00956 |
| Opus 5 | $0.00018 | $0.00478 |
| Sonnet 5 | $0.00007 | $0.00191 |
| Haiku 4.5 | $0.00004 | $0.00096 |
Grade B, and why
frontend-ui-color-reviewer scanned grade B 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 7d 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.
Strips warnings and disclaimersmediumAnti-refusal
Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend UI Color Reviewer
Activates on: palette / theme / color-token changes · dark/light theme added · oklch/hsl/rgb/hex additions · user asks about palette/colors/theme/contrast/dark mode while UI files active.
Phase 0: Context
- Read
AGENTS.mdorCLAUDE.md— product, audience, physical use context - Determine the theme decision by use context, not default preference
Theme Selection by Use Context
| Use context | Theme |
|---|---|
| Trading desk, long sessions, dim rooms | Dark |
| Hospital portal, anxious patients, phone at night | Light |
| Children's app, parent supervision | Light |
| Motorcycle forum, 9pm garage | Dark |
| SRE observability, dark office | Dark |
| Wedding planning, Sunday morning | Light |
| Music player for headphones at night | Dark |
| Food magazine over coffee | Light |
Do not default to light "to be safe" or dark "to look cool". If unclear, ask ONE question: "Is this product consumed in a physical environment that demands dark UI, or is it a default choice?"
Phase 1: Color-Space Audit
oklch()throughout, OR explicit HSL rationale#000/#fff/rgb(0,0,0)/rgb(255,255,255)in color/background/fill/stroke → CRITICAL- Tailwind
bg-black/text-white/border-blackwithout tinted tokens → WARNING - Exception:
box-shadow: rgba(0,0,0,α)is OK but tint-oklch is cleaner
Phase 2: Tinted Neutrals
Compare neutral scale against pure gray oklch(N% 0 0):
- Identical-to-pure-gray neutrals → WARNING; add chroma 0.005–0.02 toward brand hue
- Tinting must be consistent across scale (same hue, chroma stepped 0.002–0.003 between levels)
Phase 3: Palette Cohesion
- Chroma peaks in the middle of the scale, not at extremes.
oklch(80% 0.08 <h>) → oklch(60% 0.18 <h>) → oklch(25% 0.08 <h>)correct - Status colors (success / warning / error / info) as their OWN mini-palettes, not hue-shifted brand
- 60-30-10: one dominant neutral, one secondary, one rare accent. Overused accent = WARNING
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.
