+Added new `score` command that analyzes OpenAPI 3.x descriptions and produces an AI Agent Readiness score (0-100).
+Reports normalized subscores, raw per-operation metrics, and top hotspot operations with human-readable explanations. Supports `--format=stylish` (default) and `--format=json` output.

+# `score`
+
+## Introduction
+
+The `score` command analyzes an OpenAPI description and produces a composite **Agent Readiness** score (0–100) that measures how easy the API is to integrate and how usable it is by AI agents and LLM-based tooling. Higher is better.
+
+In addition to the top-level score, the command reports normalized subscores, raw metrics for every operation, and a list of **hotspot operations** — the endpoints most likely to cause integration friction — along with human-readable explanations.
+
+{% admonition type="warning" name="Important" %}
+The `score` command is considered an experimental feature. This means it's still a work in progress and may go through major changes.
+
+The `score` command supports OpenAPI 3.x descriptions only.

+
+### Metrics
+
+The following raw metrics are collected per operation and aggregated across the document:
+
+| Metric                             | Description                                                                                                                                                                                                         |
+| ---------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| Parameter count                    | Total parameters (path, query, header, cookie) per operation.                                                                                                                                                       |
+| Required parameter count           | How many of those parameters are required.                                                                                                                                                                          |
+| Request body presence              | Whether the operation defines a request body.                                                                                                                                                                       |
+| Top-level writable field count     | Number of non-`readOnly` top-level properties in request schemas.                                                                                                                                                   |
+| Max request/response schema depth  | Deepest nesting level in request and response schemas.                                                                                                                                                              |
+| Polymorphism count                 | Number of `oneOf`, `anyOf`, and `allOf` usages. `anyOf` is penalized more heavily because it allows ambiguous combinations of schemas, making it harder for consumers and AI agents to determine the correct shape. |
+| Property count                     | Total schema properties across request and response.                                                                                                                                                                |
+| Description coverage               | Fraction of operations, parameters, and schema properties that have descriptions.                                                                                                                                   |
+| Ambiguous identifier count         | Parameters with generic names (e.g. `id`, `name`, `type`) and no description.                                                                                                                                       |
+| Constraint coverage                | Count of constraining keywords (`enum`, `format`, `pattern`, `minimum`, `maximum`, `minLength`, `maxLength`, `discriminator`, etc.).                                                                                |
+| Request/response example coverage  | Whether request and response media types include `example` or `examples`.                                                                                                                                           |
+| Structured error response coverage | How many 4xx/5xx responses include a content schema or meaningful description.                                                                                                                                      |
+| Security scheme coverage           | Whether operations reference documented security schemes with descriptions.                                                                                                                                         |
+| Cross-operation dependency depth   | Inferred from shared `$ref` usage across operations. Operations that share many schemas form a dependency graph; deeper graphs indicate tightly coupled multi-step interactions.                                    |
+
+### Subscores
+
+The following subscores are normalized to 0–1 and combined into the composite Agent Readiness score:
+
+`parameterSimplicity`, `schemaSimplicity`, `documentationQuality`, `constraintClarity`, `exampleCoverage`, `errorClarity`, `dependencyClarity`, `identifierClarity`, `polymorphismClarity`, `discoverability`.
+
+The `discoverability` subscore reflects the total number of operations in the API. Larger APIs (approaching 1,000+ operations) receive a lower discoverability score because finding the right endpoint becomes harder for both humans and AI agents.
+
+### Hotspots
+
+The command identifies the operations with the lowest scores and provides reasons such as:
+
+- "High parameter count (N)"
+- "Deep schema nesting (depth M)"
+- "Polymorphism (anyOf) without discriminator"
+- "Missing request and response examples"
+- "No structured error responses (4xx/5xx)"
+- "Missing operation description"
+

+  Polymorphism Clarity     [████████████████████] 100%
+  Discoverability          [████████████████████] 100%
+
+  Top 3 Hotspot Operations
+
+  POST /orders (createOrder)
+    Agent Readiness: 38.7
+    - High parameter count (12)
+    - Deep schema nesting (depth 6)
+    - Missing request and response examples
+
+  PUT /orders/{id} (updateOrder)
+    Agent Readiness: 44.0
+    - Polymorphism (anyOf) without discriminator (3 anyOf)
+    - No structured error responses (4xx/5xx)
+```
+
+#### JSON output
+
+Use `--format=json` for machine-readable output:
+
+```bash
+redocly score openapi.yaml --format=json
+```
+
+The JSON output includes the full data: top-level scores, subscores, per-operation raw metrics, per-operation scores, dependency depths, and hotspot details with reasoning.
+
+The JSON format is suitable for CI pipelines, quality gates, or feeding results into dashboards.
