salesforce_manage_debug_logs

Enable, disable, or retrieve debug logs for Salesforce users to monitor and troubleshoot application behavior.

Instructions

Manage debug logs for Salesforce users - enable, disable, or retrieve logs.

Examples:

Enable debug logs for a user: { "operation": "enable", "username": "user@example.com", "logLevel": "DEBUG", "expirationTime": 30 }
Disable debug logs for a user: { "operation": "disable", "username": "user@example.com" }
Retrieve debug logs for a user: { "operation": "retrieve", "username": "user@example.com", "limit": 5 }
Retrieve a specific log with full content: { "operation": "retrieve", "username": "user@example.com", "logId": "07L1g000000XXXXEAA0", "includeBody": true }

Notes:

The operation must be one of: 'enable', 'disable', or 'retrieve'
The username parameter is required for all operations
For 'enable' operation, logLevel is optional (defaults to 'DEBUG')
Log levels: NONE, ERROR, WARN, INFO, DEBUG, FINE, FINER, FINEST
expirationTime is optional for 'enable' operation (minutes until expiration, defaults to 30)
limit is optional for 'retrieve' operation (maximum number of logs to return, defaults to 10)
logId is optional for 'retrieve' operation (to get a specific log)
includeBody is optional for 'retrieve' operation (to include the full log content, defaults to false)
The tool validates that the specified user exists before performing operations
If logLevel is not specified when enabling logs, the tool will ask for clarification

Implementation Reference

src/tools/manageDebugLogs.ts:103-481 (handler)

The core handler function that executes the tool logic: validates inputs, finds user, and performs enable/disable/retrieve operations on debug logs using Salesforce Tooling API (TraceFlag, DebugLevel, ApexLog).

export async function handleManageDebugLogs(conn: any, args: ManageDebugLogsArgs) {
  try {
    // Validate inputs
    if (!args.username) {
      throw new Error('username is required');
    }
    
    // Determine if the input is likely a username or a full name
    const isLikelyUsername = args.username.includes('@') || !args.username.includes(' ');

src/tools/manageDebugLogs.ts:4-85 (schema)

Tool definition including name, description, and complete inputSchema for validation of parameters like operation, username, logLevel, etc.

export const MANAGE_DEBUG_LOGS: Tool = {
  name: "salesforce_manage_debug_logs",
  description: `Manage debug logs for Salesforce users - enable, disable, or retrieve logs.
  
Examples:
1. Enable debug logs for a user:
   {
     "operation": "enable",
     "username": "user@example.com",
     "logLevel": "DEBUG",
     "expirationTime": 30
   }

2. Disable debug logs for a user:
   {
     "operation": "disable",
     "username": "user@example.com"
   }

3. Retrieve debug logs for a user:
   {
     "operation": "retrieve",
     "username": "user@example.com",
     "limit": 5
   }

4. Retrieve a specific log with full content:
   {
     "operation": "retrieve",
     "username": "user@example.com",
     "logId": "07L1g000000XXXXEAA0",
     "includeBody": true
   }

Notes:
- The operation must be one of: 'enable', 'disable', or 'retrieve'
- The username parameter is required for all operations
- For 'enable' operation, logLevel is optional (defaults to 'DEBUG')
- Log levels: NONE, ERROR, WARN, INFO, DEBUG, FINE, FINER, FINEST
- expirationTime is optional for 'enable' operation (minutes until expiration, defaults to 30)
- limit is optional for 'retrieve' operation (maximum number of logs to return, defaults to 10)
- logId is optional for 'retrieve' operation (to get a specific log)

Dispatch registration in the CallToolRequestHandler switch statement, validating arguments and calling the handleManageDebugLogs function.

A3.9/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full behavioral burden and does provide useful details: defaults, user validation, log-level enumeration, and a clarification behavior. However, it contains an internal inconsistency—logLevel is described as optional defaulting to DEBUG, but a later note says the tool will ask for clarification if it is not specified, and the schema says it is required for enable. It also does not describe side effects of enabling/disabling beyond the operation names.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is longer than average but well-structured: a summary line, concrete examples, and a notes section. Some redundancy exists between the examples and notes, but every section contributes operational value and the main purpose is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers all seven parameters, operation modes, defaults, log-levels, validation behavior, and optional flags. It does not describe the exact return structure of retrieve or any required permissions, but it is reasonably complete for invoking the tool successfully.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema documentation covers 100% of parameters, so the baseline is 3. The description adds helpful defaults, examples, and conditional dependencies, but the contradictory statements about logLevel (optional/default vs. required/ask-for-clarification) reduce its reliability for parameter usage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The opening sentence explicitly names the resource ('debug logs for Salesforce users') and the action (manage), then enumerates the three concrete operations: enable, disable, retrieve. This makes it clearly distinguishable from all sibling tools, none of which mention debug logs.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Four numbered examples show precisely which parameters are relevant for each operation, and the notes clarify defaults and constraints. There is no explicit 'when not to use' statement, but no sibling tool is a plausible alternative for debug-log management, so selection guidance is strong.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
