33 tools with mixed quality. Strengths: all tools have descriptions (10-200 chars, mostly good); input schemas present for 31/33 tools with proper types and descriptions; Norwegian naming convention consistent (source_tool pattern). Critical weaknesses: 2 tools (ogc_wfs, ngu_berggrunn, smhi_stasjoner, skolverket_skoler) lack visible input schemas in source; descriptions are functional but terse (avg ~80 chars, below 194-char baseline); no output schemas documented; no error recovery guidance; no parameter constraints (enums, ranges); no idempotency or retry semantics declared. Tool composition is sound (each does one thing), but descriptions lack 'when to use' context and dependency hints that LLMs need for selection.

• Add input schemas to ogc_wfs, ngu_berggrunn, smhi_stasjoner, skolverket_skoler. At minimum, document required parameters and their types in source.
• Document output schemas for all tools. Include field names, types, and whether results are paginated. E.g., 'Returns {items: [{id, name, ...}], total: number, next_cursor?: string}'.
• Enhance descriptions with dependency hints. E.g., 'Get values for a variable in an SSB table. Call ssb_tabell_info first to discover available variables. Returns array of {code, name} pairs.'
• Add parameter constraints: enums for categorical params (kundegruppe, katalog), min/max for numeric params (antall 1-100, timer 1-168), regex patterns for IDs (orgnr: '^[0-9]{9}$').
• Implement structured error responses with recovery guidance. E.g., '{error: "not_found", message: "Table ABC not found", retryable: false, suggestion: "Call kilder() to list available tables"}' instead of plain text.
