AgenticCrawler: Instructions file for Codex

AGENTS.md

AgenticCrawler AGENTS.md is an instructions file for Codex, OpenCode from Mingye-Lu/AgenticCrawler. It costs 6,382 tokens per session, scanned A, original, MIT.

Project instructions for AgenticCrawler, a Rust web crawler that uses an AI agent to plan browsing and extract structured information from websites.

In plain words
What is it for?
Use them when building, testing, formatting, linting, running one-shot crawl prompts, resuming prompts, or starting the crawler’s MCP server.
Why use it?
They give the coding agent the project’s commands, operating modes, setup rules, and expected exit codes, reducing mistakes when changing or running the crawler.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions subagents; mentions Claude Code; mentions AGENTS.md.

This is Mingye-Lu/AgenticCrawler's own configuration. It tells Codex and OpenCode how to work on AgenticCrawler itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything AgenticCrawler configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

AgenticCrawler 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 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.

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.

Project

acrawl is a native-Rust LLM-driven web crawler. A user provides a natural-language goal; the agent plans, navigates, and extracts structured data via a 43-tool toolbox (32 browser + 4 agent-control + 7 script). It ships as a single binary with three modes: an interactive Ratatui TUI REPL (requires a TTY), non-interactive prompt (one-shot) / --resume (slash-command replay) / run (replay a saved script with no LLM), and mcp (built-in MCP server over stdio).

cargo clippy --workspace --all-targets -- -D warnings        # lints must be clean (workspace lints set pedantic = warn)

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.
