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 | $0.04990 | $0.04990 |
| Opus 5.5 | $0.01996 | $0.01996 |
| Sonnet 5.5 | $0.00998 | $0.00998 |
| Haiku 4.5 | $0.00499 | $0.00499 |
Grade A, and why
pixelslop CLAUDE.md scanned grade A with 0 findings 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 2mo 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 223 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Pixelslop — Project Conventions
What This Is
Pixelslop is a browser-first design quality reviewer. It opens real pages in Playwright, captures screenshots and computed styles, scores design quality on 5 measurable pillars, and detects AI slop patterns. Browser evidence is the source of truth — no guessing from code.
Current Phase
Phase 5 is complete — updates and distribution. See dev_docs/MASTER-PLAN.md for the full roadmap.
What works now:
- Installer —
npx pixelslop installis interactive by default. It detects Claude Code and Codex CLI, lets the user pick runtimes and scope, supports project-local Codex installs in.codex/, rewrites paths, configures MCP, and installs skills via symlink or copy.npx pixelslop@latest updateupgrades the installed runtime set with backup + diff. - CI/CD — GitHub Actions for CI (Node 18/20/22) and automated releases via release-please + npm publish with OIDC provenance.
- Orchestrator — coordinates the full scan→fix→verify workflow. Spawns subagents, manages user interaction, groups findings by category, handles PARTIAL results. Supports
--personasand--thoroughflags. - Scanner — evaluates pages across 3 viewports, scores 5 pillars, detects 26 slop patterns, runs vision-first persona evaluation (the page-relevant subset of 8 built-ins, plus any project persona). Tested on 7 pages, scores stable within ±1.
- Persona evaluation — 8 built-in personas (screen-reader-user, low-vision-user, keyboard-user, rushed-mobile-user, slow-connection-user, non-native-english, design-critic, first-time-visitor). Extensible JSON format supports custom personas.
- Fixer — takes a scanner finding, locates the source code, creates a checkpoint via
pixelslop-tools, applies the smallest viable fix. - Checker — re-measures the targeted metric after a fix, compares before/after, returns PASS/FAIL/PARTIAL. Updates plan via
pixelslop-tools. - Setup — explores codebase for design context (framework, CSS approach, fonts, tokens), returns structured findings + questions.
- pixelslop-tools — deterministic CLI for all state management (plan, checkpoints, gates, config, init, verify). Agents call this instead of inline bash. Supports monorepo workspace detection.
- Checkpoint protocol — file-backup-based fix/verify/rollback mechanism. Both fixer and checker use
pixelslop-tools checkpoint *.
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.

pixelslop CLAUDE.md is an instructions file published in the GitHub repository gabelul/pixelslop (8 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 4,990 tokens to every session, about $0.0200 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
