Developer Growth Analysis

Developer Growth Analysis

Analyze recent Claude Code chat history, identify improvement areas, curate learning resources, and deliver a growth report to Slack DMs.

Steps

1. Read Chat History

Read ~/.claude/history.jsonl (JSONL format). Each line contains:

• display: User's message
• project: Project name
• timestamp: Unix timestamp (ms)
• pastedContents: Pasted code/content

Filter for entries from the past 24-48 hours.

2. Analyze Work Patterns

Extract from filtered chats:

• Projects/Domains: backend, frontend, DevOps, data, etc.
• Technologies: languages, frameworks, tools used
• Problem Types: debugging, feature implementation, refactoring, optimization
• Challenges: repeated questions, multi-attempt problems, knowledge gaps
• Approach Patterns: methodical, exploratory, experimental

3. Identify 3-5 Improvement Areas

Each area must be:

• Specific: not "improve coding skills" but "Advanced TypeScript generics for type-safe API responses"
• Evidence-based: grounded in actual chat history
• Actionable: practical steps to improve
• Prioritized: most impactful first

4. Generate Report

Structure the report as:

# Your Developer Growth Report
**Report Period**: [Date Range]
**Last Updated**: [Current Date]

## Work Summary
[2-3 paragraphs: projects, technologies, focus areas]

## Improvement Areas (Prioritized)
### 1. [Area Name]
**Why This Matters**: [Importance]
**What I Observed**: [Evidence from chat history]
**Recommendation**: [Concrete steps]
**Time to Skill Up**: [Effort estimate]
---
[Repeat for 2-4 more areas]

## Strengths Observed
[2-3 bullet points of things to continue]

## Action Items
1. [Highest priority action]
2. [Next action]
3. [Next action]

## Curated Learning Resources
[Populated in next step]

5. Search Learning Resources

Use HackerNews search for each improvement area:

• Query: "[Technology/Pattern] best practices", "[Topic] advanced techniques"
• Select 2-3 high-engagement articles per area
• Include: title, date, relevance description, link

6. Send to Slack DMs

• Check Slack connection via RUBESEARCHTOOLS.
• If not connected, use RUBEMANAGECONNECTIONS to initiate auth.
• Send report in logical sections using RUBEMULTIEXECUTE_TOOL.
• Confirm delivery.

Error Handling

• If ~/.claude/history.jsonl does not exist or is empty, inform the user and suggest running some Claude Code sessions first.
• If no entries found in 24-48 hours, expand the window to 7 days.
• If Slack connection fails, output the report directly in the terminal as fallback.
• If HackerNews search returns no results for an area, note it and suggest alternative search terms.
