lindas-mcp: Instructions file for Claude Code

CLAUDE.md

lindas-mcp CLAUDE.md is an instructions file for Claude Code from malkreide/lindas-mcp. It costs 5,712 tokens per session, scanned A, a copy of swisstopo-mcp CLAUDE.md, MIT.

A set of project instructions for the malkreide/lindas-mcp codebase, including its contribution conventions, tests, and steps to take before working. It is written in German.

In plain words
What is it for?
It helps update a clone correctly, identify the repository's actual default branch, run the pinned checks, and diagnose failures in the project's test and CI workflow.
Why use it?
It helps developers avoid working from an outdated copy, assuming the wrong default branch, or running checks with tool versions that differ from CI. It also defines how to investigate failing tests.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Codex.

This is malkreide/lindas-mcp's own configuration. It tells Claude Code how to work on lindas-mcp 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 lindas-mcp configures →

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

lindas-mcp CLAUDE.md scanned grade A with 1 finding 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 8d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 425 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

Teil 1 — Portfolio-Konventionen

Vor der Arbeit

Klon-Aktualität prüfen — Standard-Branch ermitteln, nicht main annehmen:

B=$(git ls-remote --symref origin HEAD | sed -n 's|^ref: refs/heads/\([^[:space:]]*\).*|\1|p')
git fetch origin "${B:?Standard-Branch nicht ermittelbar}" &&
  git rev-list --count HEAD..FETCH_HEAD

Drei Server im Portfolio heissen ihren Standard-Branch master (openlex-mcp, swiss-courts-mcp, swisstopo-mcp); dort scheitert ein fest verdrahtetes origin/main mit «couldn't find remote ref main». Wer das für ein Netzproblem hält, arbeitet weiter auf genau dem veralteten Klon, vor dem dieser Absatz warnt. Den :?-Schutz nicht weglassen: Bei leerem B fetcht git still den Remote-HEAD und endet mit 0.

Ein veralteter Klon erzeugt eine rote CI, deren Ursache nicht im Diff steht. Am 3.8.2026 zweimal passiert — beide Male fehlten genau die Commits, die das Gate einführten, an dem der Branch scheiterte.

Gates lokal fahren, mit der GEPINNTEN ruff-Version aus der CI. Eine andere Version meldet Abweichungen, die niemand verursacht hat.

Tests

Gegenprobe ist Pflicht. Ein Test, der grün bleibt, wenn man die Implementierung entfernt, prüft nichts. Jede neue Zusicherung einzeln neutralisieren und zeigen, dass genau die zugehörigen Tests fallen.

Zwei Fallen, die beide grün blieben:

  • Eine Fake-Uhr, die nur beim Schlafen vorrückt, kann eine Zusicherung über echte Zeit nicht widerlegen.
  • monkeypatch.setattr(modul.asyncio, "sleep", ...) greift ins Modul asyncio selbst und entschärft die Mechanik im ganzen Prozess. Patche einen Modul-Alias (_sleep = asyncio.sleep), nicht das fremde Modul.

Handgeschriebene Fixtures kodieren die Annahme des Autors und können sie nicht widerlegen. Mindestens eine aufgezeichnete Antwort pro externem Endpunkt, mit Aufnahmedatum.

Wenn etwas rot ist

Roter Live-Test: erst die Quelle abfragen, dann einordnen. Nicht aus der Fehlermeldung schliessen. Am 3.8.2026 hiess "nicht gefunden" nicht, dass der Datensatz weg war, sondern dass die Quelle die Schreibweise ihrer Kopfzeile gewechselt hatte — vier von sechs Datensätzen produktiv kaputt, alle Unit-Tests grün.

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.
