🧠 PRIMARY TOOL ⭐ ALWAYS USE THIS FIRST for ANY German legal question ⭐

What this tool searches: • Full-text search across rechtsinformationen.bund.de • Both legislation (Gesetze) AND case law (Rechtsprechung) • Intelligent query enhancement with misconception correction

⚠️ DATABASE COVERAGE LIMITATIONS: • Grundgesetz (GG): NOT in database - only laws referencing GG are available • SGB I-VIII: NOT in database - SGB IX-XIV available, earlier books missing • Historic laws: Limited coverage, focus on current legislation post-2000 • Amendments: Newer amendment laws well-covered, older may be missing • If a law is not found, it may not be in the testphase database yet

Intelligent Features (Automatic): ✓ English → German translation (e.g., "employee rights" → "Arbeitnehmerrechte") ✓ Misconception correction (e.g., "Überprüfungsantrag" → "Widerspruch") ✓ Legal reference extraction (e.g., detects "§ 15 BEEG" patterns) ✓ Multiple search term execution in parallel ✓ Result prioritization and deduplication

Data Model Understanding (CRITICAL for answering questions): Results follow FRBR model with three levels:

1. Work (Abstract): The law as intellectual creation

2. Expression (Version): Specific publication with metadata

3. Manifestation (Format): HTML links for reading, JSON-LD for metadata

Metadata Available in Search Results: • Immediately available (no follow-up needed):

• legislationDate - When the law was passed/enacted

• datePublished - When published in Federal Law Gazette (BGBl)

• name - Full law title

• abbreviation - Official abbreviation (BGB, StGB, etc.)

• Requires follow-up call (use gesetz_per_eli_abrufen):

• temporalCoverage - Date range when law is/was in force

• inForce - Current validity status (boolean)

• Full text content and structure

Results contain: • HTML links (Manifestation): [Law Name] for users to read • Basic metadata (Expression): Legislation date, published date immediately visible • Detailed metadata: Use gesetz_per_eli_abrufen for inForce status and temporal coverage

Example Use Cases: • "When was BGB enacted?" → Check legislationDate in results (immediate) • "When was BGB published?" → Check datePublished in results (immediate) • "Is SGB IX still valid?" → Use gesetz_per_eli_abrufen for inForce status (follow-up) • "Show me § 242 StGB" → Use HTML link for law text (immediate)

What this tool does NOT do: ✗ Does NOT perform true semantic search with ML embeddings ✗ Does NOT generate semantically similar terms (YOU must provide variations) ✗ Does NOT try multiple query phrasings (YOU must search with different terms) ✗ Does NOT explore related concepts automatically (YOU need multiple searches) ✗ Uses keyword matching + Fuse.js fuzzy search (not neural embeddings)

AI Agent Responsibilities: As the calling agent, YOU must:

1. Provide multiple query variations (synonyms, related terms, different phrasings)

2. Search for law abbreviations separately (BEEG, BGB, SGB, etc.)

3. Try specific § references when mentioned (§ 44 SGB X)

4. Search for amendment laws with different patterns

5. Use specialized tools (deutsche_gesetze_suchen, rechtsprechung_suchen) for follow-up

Search Strategies for Common Questions:

Amendment questions: • "X Änderungsgesetz 2021" • "Gesetz zur Änderung X 2021" • "BGBl 2021 X" (Federal Law Gazette) • Search both enactment year AND effective year

Law interpretation: • Search law name + specific § reference • Try both formal name and abbreviation • Search for related commentary or court decisions

Case law: • Search topic + "BGH" or court name • Try legal concepts + "Rechtsprechung" • Search ECLI or case file numbers if known

Parameters: • query: Your search query in German or English (required) • threshold: Fuzzy match threshold 0.0-1.0 (default: 0.3, lower = more results) • limit: Max results (default: 5, API max: 100)

Usage Pattern:

1. Start here for ALL legal questions

2. Analyze results for relevant documents

3. Use specialized tools for follow-up (deutsche_gesetze_suchen, rechtsprechung_suchen)

4. Use dokument_details_abrufen for full text of specific documents

5. Try query variations yourself if results insufficient
