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 | $0.01238 | $0.01238 |
| Opus 5 | $0.00619 | $0.00619 |
| Sonnet 5 | $0.00248 | $0.00248 |
| Haiku 4.5 | $0.00124 | $0.00124 |
Grade A, and why
browser-jet-pilot AGENTS.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 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.
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 — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Instructions
Mandatory First Step
Read docs/CODING_STYLE.md before touching any code. Every change must comply with formatting, documentation, and type safety standards defined there.
Project Overview
Browser Jet Pilot is a self-hosted MCP server for browser automation via Playwright + CDP. It exposes 26 deterministic tools through JSON-RPC 2.0 (stdio and HTTP transports), with an optional AI agent layer (BrowserAgent) and skill interface (BrowserSkill).

Architecture
src/index.ts → Server entry, transport setup, tool registration
src/config.ts → Zod-validated env config (CDP_URL, LAUNCH, PORT, API_KEY, ...)
src/session.ts → SessionManager — CDP connect or Playwright launch, browser lifecycle
src/types.ts → Shared interfaces (BrowserSession, ServerConfig, ToolResult)
src/webdav.ts → WebDAV handler for session file access
src/tools/index.ts → Tool registration hub — wires 26 tools into the MCP server
src/tools/utils.ts → Shared helpers (getSession, DATA_DIR, DOWNLOADS_DIR)
src/tools/session.ts → browser_start, browser_end
src/tools/navigation.ts → browser_navigate, browser_get_info
src/tools/interaction.ts → browser_click, browser_fill, browser_type, browser_select, browser_hover, browser_scroll
src/tools/observation.ts → browser_screenshot, browser_evaluate, browser_get_content, browser_wait_for
src/tools/persistence.ts → browser_save_cookies, browser_load_cookies, browser_download, browser_list_data_files, browser_read_data_file, browser_write_data_file, browser_delete_data_file
src/tools/tabs.ts → browser_new_tab, browser_list_tabs, browser_switch_tab
src/tools/shader.ts → browser_disable_shaders, browser_restore_shaders
src/agent/ → BrowserAgent (AI loop) + CLI
src/skill/ → BrowserSkill (framework integration) + manifest JSON
src/scripts/ → Self-test scripts for coding style, formatting, linting, typecheck
docs/ → Mintlify documentation (docs.json is the nav config)
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.
