Generate Doc Description - Anypoint Platform APIs

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:

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)

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...

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
