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 | $0.03451 | $0.03451 |
| Opus 5.5 | $0.01380 | $0.01380 |
| Sonnet 5.5 | $0.00690 | $0.00690 |
| Haiku 4.5 | $0.00345 | $0.00345 |
Grade A, and why
humanjs 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 — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HumanJS
Humanized browser automation for AI agents, QA tests, and demos. Playwright-first.
This file is the brief loaded into every Claude session in this repo. Keep it lean. Architectural reasoning lives in
docs/DESIGN.md(public). Strategic and personal notes live indocs/PROJECT_BRIEF.md(local-only, gitignored).
Project status
Greenfield — no code yet. We're scaffolding the v1 monorepo from scratch.
Positioning (immutable)
HumanJS humanizes browser automation for AI agents, QA tests where real-pace timing exposes bugs, and demo/tutorial recordings.
When writing copy, docs, examples, or comments: never frame the project around scraping, captcha bypass, or "undetectable" automation. The audience is AI agent builders, QA engineers, and demo/tutorial creators.
Non-goals — refuse to implement
If asked, decline and link to this section.
- Captcha solvers / captcha bypass
- Fingerprint masking or browser fingerprint spoofing
- Proxy rotation or IP management
- TLS / network-level stealth
- "Undetectable" claims anywhere in any artifact
- Time-of-day variation (gimmick, no real value)
- AI-generated mouse trajectories (worse than Bezier, vastly more expensive)
Naming
- Brand: HumanJS
- Primary npm scope:
@humanjs/* - Fallback scope:
@totigm/humanjs(used only if@humanjsorg isn't claimable on first publish) - Domain: humanjs.dev (planned)
Verified available on npm at project start: @humanjs/core, @humanjs/playwright, @humanjs/recorder, @humanjs/mcp, @humanjs/generator, @humanjs/skill, @humanjs/recipes. Unscoped humanjs is owned by a dormant 2022 package — irrelevant scope, doesn't block us.
Architecture
- Monorepo (pnpm workspaces, optionally Turborepo). Each package independently versioned.
- Playwright-first. Puppeteer adapter is roadmap, not v1.
- Plugin system from day one. Even if v1 ships no plugins, the architecture supports extending personalities, primitives, and behaviors via plugins. Non-negotiable architectural decision.
- TypeScript strict. ESM-first with CJS dual-publish where needed.
- MIT licensed.
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.
- 2mo ago First seen · 250 lines · 3,451 tokens per session scan A c90a0e65fe3d
humanjs CLAUDE.md is an instructions file published in the GitHub repository totigm/humanjs (23 stars, last pushed today), licensed MIT. It adds 3,451 tokens to every session, about $0.0138 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 2026-08-30.
