handelsregister-cli AGENTS.md

Project instructions for using the German commercial register, an official source of company documents such as shareholder lists and articles of association, through the hreg command-line tool.

In plain words
What is it for?
Use them to install and run hreg, search for companies, identify the correct court and register number, and fetch official German commercial-register documents.
Why use it?
They reduce the risk of guessing a company identity or using the wrong register document. The instructions require searching first and confirming among similar results.

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

handelsregister-cli 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 yesterday.

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.

Instructions for AI agents

You have been pointed at handelsregister-cli to fetch official German commercial-register documents (Handelsregister) — e.g. a Gesellschafterliste (shareholder list), Gesellschaftsvertrag (articles of association), or a current printout — for a company. Follow this recipe exactly.

1. Install the hreg CLI (once)

Check first: hreg --version. If missing, install with the first of these tools that exists on the machine:

uv tool install git+https://github.com/DespotB/handelsregister-cli
# or
pipx install git+https://github.com/DespotB/handelsregister-cli
# or
pip install --user git+https://github.com/DespotB/handelsregister-cli

If hreg is still not found afterwards, the install bin directory is probably not on PATH — try ~/.local/bin/hreg --version and call it by that path. If all installers fail, report what needs to be installed and stop.

No accounts, API keys, or fees are needed; the register is free by law.

2. Search first, never guess

hreg search "<company keywords>" --json
  • No results: broaden the keywords or add --mode any.
  • Several plausible results: show name + court + register number and ask the user which one is meant, unless they already gave a register number.

3. Fetch

hreg fetch "<keywords>" --register "<HRB/HRA number>" -o "<outdir>" --json
  • Default downloads everything; narrow with --docs AD,CD,SI,DK (Gesellschafterlisten and Gesellschaftsverträge live in the DK folder).
  • The command is slow by design (~3 s between requests; a full fetch takes minutes). Never lower --delay below 3 and never loop over many companies — the portal rate-limits at roughly 60 requests/hour.

4. Report

Read manifest.json in the output directory and summarise: which documents were downloaded (highlight Gesellschafterlisten and Gesellschaftsverträge with their dates), what was skipped and why, and where the files are. Duplicates are already removed by SHA-256 checksum; "skipped: empty category" entries are portal-tree duplicates, not errors.

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.
