## Tools (as reported by the server, not verified)

- `get\_cracks\_index`: Return the full country ranking for the latest published snapshot.
- `compare\_countries`: Compare the composite score and rank of several countries. \`\`iso3\_list\`\` is a list of ISO-3166 alpha-3 country codes.
- `country\_detail`: Return one country's score, rank and per-indicator breakdown.
- `country\_fix`: Return the single highest-impact improvement for one country. The Cracks Index names, alongside each country's score, the one change most associated with the fastest improvement, turning a ranking into a constructive, actionable signal. Read-only, no personal data.
- `get\_regions`: List sub-national areas in the Cracks Index, ranked within their level. The index covers sub-national areas as well as countries: EU regions \(NUTS-2\) and Dutch municipalities. This tool returns those areas with their composite score and rank. Parameters ---------- level : optional Filter by area lev
- `region\_detail`: Return one sub-national area: score, rank, indicator breakdown and fix. Given a region code \(an EU NUTS-2 code or a Dutch municipality CBS GM-code\), returns that area's composite score, its rank within its own level \(regions rank against regions, municipalities against municipalities\), the per-indic
- `improvement\_guidance`: Return constructive improvement guidance for one area. Given an area identifier — an ISO-3166 alpha-3 country code, an EU NUTS-2 region code or a Dutch municipality CBS GM-code — returns that area's highest-impact improvement lever from the Cracks Index, together with Fynqo's approach to earlier, jo
- `methodology`: Return the index methodology: indicators, weights, direction, sources.
- `score\_trends`: Return one area's composite-score history across every snapshot. Given an area identifier — an ISO-3166 alpha-3 country code, an EU NUTS-2 region code or a Dutch municipality CBS GM-code — walks every published Cracks Index snapshot and returns that area's composite score and rank at each point in t
- `top\_movers`: Return the biggest risers and fallers between the two latest snapshots. Compares every area's composite score in the most recent snapshot against the snapshot before it and returns the areas that improved most \(\`\`improvers\`\` — score fell\) and worsened most \(\`\`decliners\`\` — score rose\). Needs at leas
- `indicator\_ranking`: Rank all areas by a single chosen indicator. Returns every area's value for one indicator, ordered best-first by the direction-corrected \`\`normalized\_score\`\` \(a higher normalised score always means fewer cracks on that indicator\). The raw value and unit are included so the figure can be quoted direc
- `indicator\_correlations`: Return pairwise correlations between the six indicators across areas. Computes the Pearson correlation coefficient between every pair of the six Cracks Index indicators, using each area's direction-corrected normalised score. Adds a short plain-language note naming the strongest relationship. A coef
- `area\_statistics`: Return where one area sits statistically within its own level. Places an area against its peer group \(all areas at the same level in the latest snapshot\): its percentile, the distance from its composite score to the level median, best and worst, and the handful of areas nearest to it by score. Usefu
- `gemeente\_social\_profile`: Return the Dutch social-domain profile for one municipality. Given a CBS GM-code, returns that municipality's four v1 social-domain indicators — social-assistance receipt, modelled homelessness, Wmo use and youth-care use — each with its raw value, source and whether it was measured or modelled. The
- `compare\_gemeenten`: Compare the social-domain profile of several Dutch municipalities. Given two to six CBS GM-codes, returns a side-by-side comparison of their four v1 social-domain indicators plus composite score and rank. Useful for an agent answering "how does municipality A compare to B on the social domain". Read
