+# JWT Parser Function
+
+A Serverless Workflow 1.x function that decodes JWT (JSON Web Token) payloads using jq expressions. This function provides pure jq-based JWT parsing without external dependencies.
+
+## Technical Implementation
+
+This function implements JWT payload extraction through a `run` task using jq expressions:
+
+**Core JWT Decoding Logic:**
+```jq
+(if (.token | startswith("Bearer ")) then .token[7:] else .token end) |
+split(".") |
+if length != 3 then error("Invalid JWT format: must have 3 parts") else .[1] end |
+@base64d |
+fromjson
+```
+
+**Technical Steps:**
+1. **Prefix Handling**: Detects and removes "Bearer " prefix if present
+2. **Token Splitting**: Splits JWT on "." to isolate header, payload, signature
+3. **Format Validation**: Ensures exactly 3 parts (header.payload.signature)
+4. **Payload Extraction**: Selects the middle part (index 1) containing claims
+5. **Base64 Decoding**: Uses `@base64d` to decode the base64url payload
+6. **JSON Parsing**: Converts decoded string to JSON object with `fromjson`
+7. **Optional Claim Navigation**: Uses jq path expressions for specific claim extraction
+
+## Usage
+
+### Complete Payload Extraction
+
+```yaml
+document:
+  dsl: 1.0.0-alpha1
+  namespace: technical
+  name: jwt-full-decode
+  version: 1.0.0
+do:
+  - decodeJWT:
+      call: jwt-parser
+      with:
+        token: ${ .headers.authorization }
+        # Returns: complete JWT payload as JSON object
+```
+
+### Specific Claim Extraction
+
+```yaml
+document:
+  dsl: 1.0.0-alpha1
+  namespace: technical
+  name: jwt-claim-extraction
+  version: 1.0.0
+do:
+  - extractSubject:
+      call: jwt-parser
+      with:
+        token: ${ .headers.authorization }
+        claimPath: ".sub"
+        # Returns: "user-id-123"
+  - extractNestedClaim:
+      call: jwt-parser
+      with:
+        token: ${ .headers.authorization }
+        claimPath: ".custom.department"
+        # Returns: "engineering"
+```
+
+### Token Format Handling
+
+```yaml
+document:
+  dsl: 1.0.0-alpha1
+  namespace: technical
+  name: jwt-format-handling
+  version: 1.0.0
+do:
+  - parseRawToken:
+      call: jwt-parser
+      with:
+        token: "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIn0.signature"
+  - parseBearerToken:
+      call: jwt-parser
+      with:
+        token: "Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIn0.signature"
+        # Both handle the token format automatically
+```
+
+## Function Specification
+
+### Input Parameters
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `token` | string | Yes | JWT token (raw or with "Bearer " prefix) |
+| `claimPath` | string | No | jq path expression for specific claim extraction |
+
+### Output Structure
+
+**When `claimPath` is NOT provided** (complete payload):
+```json
+{
+  "sub": "user-123",
+  "preferred_username": "john.doe",
+  "email": "john@example.com",
+  "exp": 1234567890,
+  "iat": 1234567800
+}
+```
+
+**When `claimPath` is provided** (specific claim value):
+```json
+"user-123"
+```
+or
+```json
+"engineering"
+```
+
+## Technical Details
+
+### JWT Token Structure
+```
+header.payload.signature
+```
+The function processes the **payload** section (index 1 after splitting on ".")
+
+### jq Expression Breakdown
+
+**JWT Decoding Expression:**
+```jq
+(if (.token | startswith("Bearer ")) then .token[7:] else .token end) |
+split(".") |
+if length != 3 then error("Invalid JWT format: must have 3 parts") else .[1] end |
+@base64d |
+fromjson
+```
+
+**Claim Path Expression:**
+```jq
+((if (.token | startswith("Bearer ")) then .token[7:] else .token end) |
+split(".") |
+if length != 3 then error("Invalid JWT format: must have 3 parts") else .[1] end |
+@base64d |
+fromjson) as $decoded |
+if (.claimPath // null) != null then
+  (.claimPath | split(".") | map(select(. != ""))) as $path |
+  $decoded | getpath($path)
+else
+  $decoded
+end
+```
+
+### Supported Token Formats
+- **Raw JWT**: `eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0In0.sig`
+- **Bearer Format**: `Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0In0.sig`
+
+### Claim Path Examples
+| Path | Description | Example Result |
+|------|-------------|----------------|
+| `.sub` | Subject identifier | `"user-123"` |
+| `.preferred_username` | Username | `"john.doe"` |
+| `.custom.department` | Nested custom claim | `"engineering"` |
+| `.roles[0]` | First role in array | `"admin"` |
+
+## Error Conditions
+
+The function will fail with jq errors if:
+- **Invalid token format**: Not exactly 3 parts separated by dots
+- **Invalid base64**: Payload section cannot be base64 decoded
+- **Invalid JSON**: Decoded payload is not valid JSON
+- **Invalid claim path**: Specified jq path does not exist in payload
+
+## Implementation Notes
+
+- **No signature verification**: Function extracts claims without cryptographic validation
+- **Base64URL decoding**: Uses jq's `@base64d` which handles base64url format  
+- **Path navigation**: Uses `getpath()` with string splitting for safe claim extraction
+- **Prefix handling**: Conditional logic automatically detects and strips "Bearer " prefix
+- **Pipeline processing**: Uses jq pipe operators for clean data transformation flow
+- **Null safety**: Uses `has("claimPath")` to check for optional parameter presence
+
+## Technical Validation
+
+### JWT Structure Validation
+The function expects standard JWT format: `header.payload.signature`
+- **Header**: Algorithm and token type (ignored)
+- **Payload**: Base64URL-encoded JSON claims (processed)  
+- **Signature**: Cryptographic signature (ignored)
+
+### Base64URL Decoding
+JWT uses Base64URL encoding (RFC 4648 Section 5):
+- Uses `-` and `_` instead of `+` and `/`
+- No padding characters required
+- jq's `@base64d` handles this automatically
+
+### Claim Path Syntax
+Claim paths follow jq object navigation:
+- `.sub` - Direct property access
+- `.custom.department` - Nested object access  
+- `.roles[0]` - Array element access
+- Path components split on `.` and filtered for non-empty strings
