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 | $0.01465 | $0.01465 |
| Opus 5 | $0.00732 | $0.00732 |
| Sonnet 5 | $0.00293 | $0.00293 |
| Haiku 4.5 | $0.00146 | $0.00146 |
Grade C, and why
claude-web-animations CLAUDE.md scanned grade C 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 9d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- **Never auto-delete this folder.** The user clears it with `rm -rf .screenshots/` whenever they want. How it starts
The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — Web Design
A general operating manual for any web design project. Project-specific details (stack, brand, file structure) belong in a separate CLAUDE.md layered on top of this one.
Non-negotiables
- Two-pass screenshot verification for every visual change. Reading code is not seeing the result.
- Parallel execution for independent file work — components, styles, tests, and stories ship in one batch.
- Use the design tools you actually have. See the Tools section below before defaulting to "I'll just write it blind."
Two-pass screenshot workflow
Whenever you make a visual change, add a component, or are asked to evaluate how something looks, screenshot the rendered output twice.
Pass 1 — Baseline. Render the current state. Capture at desktop (1440×900) and mobile (390×844). Write 3–5 specific observations: what works, what breaks, what feels off. This pass is diagnostic — do not skip to fixing.
Pass 2 — Verification. Apply the change. Re-screenshot at the same viewports as Pass 1. Compare directly. Did the fix land? Any regressions? If Pass 2 doesn't resolve what Pass 1 revealed, iterate — don't ship.
When this is required: after creating or modifying any component, after the user says "this doesn't look right," before declaring any task complete, and any time you're evaluating your own visual work.
Screenshot storage (mandatory)
All screenshots go in .screenshots/ at the project root. This folder is disposable and user-owned.
- Add
.screenshots/to.gitignoreon first use. - One subfolder per task:
.screenshots/<task-slug>/ - Filename format:
pass-<1|2>-<viewport>-<timestamp>.png- Example:
.screenshots/hero-redesign/pass-2-mobile-2026-04-24T14-31.png
- Example:
- Never overwrite — timestamps preserve iteration history.
- Never auto-delete this folder. The user clears it with
rm -rf .screenshots/whenever they want. - Create the folder if it doesn't exist before taking the first shot of a session.
- Never save screenshots anywhere else (not
src/, notpublic/, not the project root).
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.

claude-web-animations CLAUDE.md is an instructions file published in the GitHub repository TommyChryst/claude-web-animations (45 stars, last pushed 4mo ago), licensed MIT. It adds 1,465 tokens to every session, about $0.0073 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
