Generate Linear Work Log

You are tasked with generating a technical work log comment for a Linear issue based on recent git commits.

Instructions

1. Check Linear MCP Availability

   • Verify that Linear MCP tools are available (mcp__linear__* functions)
   • If Linear MCP is not installed, inform the user to install it and provide installation instructions
   • Do not proceed with work log generation if Linear MCP is unavailable

2. Check for Existing Work Log

   • Use Linear MCP to get existing comments on the issue
   • Look for comments with today's date in the format "## Work Completed [TODAY'S DATE]"
   • If found, note the existing content to append/update rather than duplicate

3. Extract Git Information

   • Get the current branch name
   • Get recent commits on the current branch (last 10 commits)
   • Get commits that are on the current branch but not on main branch
   • For each relevant commit, get detailed information including file changes and line counts
   • Focus on commits since the last work log update (if any exists)

4. Generate Work Log Content

   • Use dry, technical language without adjectives or emojis
   • Focus on factual implementation details
   • Structure the log with date, branch, and commit information
   • Include quantitative metrics (file counts, line counts) where relevant
   • Avoid subjective commentary or promotional language

5. Handle Existing Work Log

   • If no work log exists for today: Create new comment
   • If work log exists for today: Replace the existing comment with updated content including all today's work
   • Ensure chronological order of commits
   • Include both previous and new work completed today

6. Format Structure

   ## Work Completed [TODAY'S DATE]
   
   ### Branch: [current-branch-name]
   
   **Commit [short-hash]: [Commit Title]**
   - [Technical detail 1]
   - [Technical detail 2]
   - [Line count] lines of code across [file count] files
   
   [Additional commits in chronological order]
   
   ### [Status Section]
   - [Current infrastructure/testing status]
   - [What is now available/ready]

7. Post to Linear

   • Use the Linear MCP integration to create or update the comment
   • Post the formatted work log to the specified Linear issue
   • If updating, replace the entire existing work log comment
   • Confirm successful posting

Git Commands to Use

• git branch --show-current - Get current branch
• git log --oneline -10 - Get recent commits
• git log main..HEAD --oneline - Get branch-specific commits
• git show --stat [commit-hash] - Get detailed commit info
• git log --since="[today's date]" --pretty=format:"%h %ad %s" --date=short - Get today's commits

Content Guidelines

• Include commit hashes and descriptive titles
• Provide specific technical implementations
• Include file counts and line counts for significant changes
• Maintain consistent formatting
• Focus on technical accomplishments
• Include current status summary
• No emojis or special characters

Error Handling

• Check if Linear MCP client is available before proceeding
• If Linear MCP is not available, display installation instructions:
  Linear MCP client is not installed. To install it:
  
  1. Install the Linear MCP server:
     npm install -g @modelcontextprotocol/server-linear
  
  2. Add Linear MCP to your Claude configuration:
     Add the following to your Claude MCP settings:
     {
       "mcpServers": {
         "linear": {
           "command": "npx",
           "args": ["@modelcontextprotocol/server-linear"],
           "env": {
             "LINEAR_API_KEY": "your_linear_api_key_here"
           }
         }
       }
     }
  
  3. Restart Claude Code
  4. Get your Linear API key from: https://linear.app/settings/api

• Validate that the Linear ticket ID exists
• Handle cases where no recent commits are found
• Provide clear error messages for git operation failures
• Confirm successful comment posting

Example Usage

When invoked with /generate-linear-worklog BLA2-2, the command should:

1. Analyze git commits on the current branch
2. Generate a structured work log
3. Post the comment to Linear issue BLA2-2
4. Confirm successful posting
