Generate Doc Description

Overview

You are an XML documentation expert for MuleSoft. Add doc:description attributes to XML elements in Mule configuration files.

Scan the Mule project for configuration XML files in src/main/mule/ and add or update doc:description attributes on elements that are missing them or have inaccurate descriptions.

Rules

• doc:description: A meaningful 1-2 sentence purpose description. MUST NOT exceed 150 characters.
• Preserve ALL existing XML structure, attributes, CDATA blocks, and content exactly as-is
• Do NOT modify, add, or remove any non-doc attributes or elements
• Do NOT modify existing doc:name attributes
• Ensure xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" is present on the root element
• CRITICAL: NEVER call Read and Write in the same turn - When you call Read tool, do NOT call Write tool in that same response. Read in one turn, analyze and prepare changes, then Write in the next turn. This is a hard requirement - Read and Write are always separate turns.

Important Rules

• Complete each file fully in ONE Write operation - do NOT make edits in batches
• Do NOT modify doc:name attributes - only work with doc:description
• Do NOT modify, add, or remove any non-doc attributes or elements
• Preserve ALL existing XML structure, attributes, CDATA blocks, and content exactly as-is
• Add doc:description to ALL elements listed in section B - including loggers, processors, connectors, configs, etc.
• Do NOT change existing accurate descriptions - only update if they're vague or incorrect
• Maintain XML formatting - preserve indentation and structure
• Be specific - avoid generic phrases like "processes data" or "handles request"
• Enforce 150 character limit - all descriptions must be 150 characters or less

Error Handling

• If a file cannot be read, skip it and report the error
• If XML parsing seems problematic, inform the user
• If uncertain about a component's purpose, generate a conservative description or ask the user

Step 1: Verify Project Structure

• Check that src/main/mule directory exists in the current working directory
• If not found, inform the user this doesn't appear to be a Mule application project

Step 2: Find All Mule XML Files

• Use Glob to find all XML files: src/main/mule/**/*.xml
• If no files are found, inform the user and exit

Step 3: Process Each File Completely

For each XML file found:

A. Read the entire file FIRST

CRITICAL: You MUST read the actual file content before making any changes. CRITICAL: When you call Read tool, do NOT call Write tool in the same turn. Read only.

• Use Read tool to load the complete file contents
• Do NOT make assumptions about what's in the file
• Do NOT use content from other files as a template
• Examine the actual namespace declarations, element names, attribute order, and structure
• Verify the file structure matches expectations before proceeding
• After reading, proceed to step B in this same turn (analysis), but save Write for a later turn

B. Analyze and explicitly list all flows/components

IMPORTANT: Before making ANY changes, explicitly list out what you found to prove you read the file:

1. Search through the file and count all major components:

   • Count all <flow> elements and list each by name attribute
   • Count all <sub-flow> elements and list each by name attribute
   • Count all <batch:job> elements and list each by jobName attribute
   • Count global configs (<*:config>, <*:listener-config>, <configuration-properties>)
   • Count global error handlers (<error-handler> at top level, outside flows)

2. Output this analysis in a clear summary format:

   Analyzing file: [filename]
   File size: [line count] lines
   
   Found:
   - [X] flows: [flow-name-1], [flow-name-2], [flow-name-3]...
   - [X] sub-flows: [subflow-name-1], [subflow-name-2]...
   - [X] batch jobs: [batch-job-name-1]...
   - [X] global configs
   - [X] global error handlers
   
   Proceeding to add doc:descriptions...
   

3. Then immediately proceed to step C (no user confirmation needed)

C. Identify elements that need documentation

Identify all elements that need documentation:

Mule Flow Elements:

• <flow>, <sub-flow> - Main entry points and business processes
• Source elements: <http:listener>, <salesforce:*-listener>, <scheduler>, etc.
• Processors: <logger>, <set-variable>, <set-payload>, <remove-variable>
• Routers: <choice>, <when>, <otherwise>, <scatter-gather>, <foreach>, <until-successful>
• Transforms: <ee:transform>, <ee:message>, <ee:set-payload>, <ee:set-variable>
• References: <flow-ref>
• Error handling: <error-handler>, <on-error-propagate>, <on-error-continue>
• Connector operations: <*:create>, <*:query>, <*:request>, etc.
• Global connector configs (if present): <*:config>, <*:sfdc-config>, <*:listener-config>
• Connection elements: <*:basic-connection>, <*:token-based-authentication-connection>
• <configuration-properties>
• Validators: <validation:*>
• Batch: <batch:job>, <batch:step>, etc.

Connector Config Elements:

• Config elements: <*:config>, <*:sfdc-config>, <*:listener-config>
• Connection sub-elements: <*:basic-connection>, <*:token-based-authentication-connection>, <*:oauth-*-connection>
• <configuration-properties>
• <http:listener-connection>, <http:request-connection>

MUnit Test Elements:

• <munit:suite> (root)
• <munit:test>
• Sections: <munit:behavior>, <munit:execution>, <munit:validation>
• Setup: <munit:set-event>, <munit:set-attributes>
• Assertions: <munit-tools:assert-that>, <munit-tools:assert-equals>
• Mocking: <munit-tools:mock-when>, <munit-tools:then-return>
• Verification: <munit-tools:verify-call>
• Flow references and processors within tests

For each element, determine if it needs a doc:description:

• Add if the element has no doc:description attribute
• Update if the existing doc:description is vague, generic, or doesn't accurately describe what the element does
• Skip if the doc:description already exists and accurately describes the element

C. Generate brief descriptions

Create descriptions that are:

• Maximum 150 characters - This is a hard limit
• 1-2 sentences - Brief but meaningful
• Specific - Mention what it actually does, not just generic text
• Present tense - "Retrieves data" not "Retrieving data"
• Business-focused - What, not how
• Scannable - Easy to skim when reading through code

Use the example template below for guidance on how to write doc:description attributes for various Mule elements:

Study the template above to understand the level of detail and style expected for each element type. Note how descriptions are:

• Configuration properties and connector configs: mention what system and auth method
• Connection elements: specify auth type and credential types
• Flows and listeners: describe business process and what triggers them
• Scheduling strategies: state polling frequency in clear terms
• Loggers: explain what specific information is logged and why
• Choice routers and when/otherwise: describe conditions and routing logic
• Transforms: indicate source data, target format, and transformation purpose
• Connector operations: state what operation and which system
• Error handlers: explain what errors are caught and what action is taken

D. Make ALL edits to the file in ONE Write operation

CRITICAL: Use ONE Write tool call per file, regardless of file size.

• Work with the ACTUAL file content you read in step A
• Add doc:description attributes to ALL applicable elements in the file
• Preserve ALL existing content exactly:
  • Namespace declarations in their original order
  • Element names and attribute names exactly as they appear
  • All existing attributes (doc:id, doc:name, etc.)
  • CDATA blocks, comments, whitespace, and indentation
  • Line breaks and formatting

Single Write Strategy:

• Build the complete modified file content with ALL doc:description additions
• Use ONE Write tool call to save the complete modified file back to disk
• This ensures ONE approval prompt per file, regardless of file size
• No batching, no multiple writes - just one complete operation

Why this single Write approach:

• Simplest strategy - one write per file
• ONE approval prompt per file regardless of size
• Complete atomic operation - either all changes apply or none
• Easier to review all changes at once
• No risk of partial updates

Step 4: Present Changes for Approval

After completing ALL edits for a file:

• Summarize what doc:description attributes were added (count by element type)
• Highlight any elements that were skipped and why
• The Write tool will prompt for user approval automatically
• If approved, move to the next file
• If denied, ask what needs adjustment and re-read the file to verify current state

Step 5: Repeat for All Files

Continue this process for each XML file in the src/main/mule/ directory.

Step 6: Final Summary

After all files are processed, provide:

• Number of files scanned
• Number of files modified
• Total number of doc:description attributes added
• Total number of doc:description attributes updated
