Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00047 | $0.03177 |
| Opus 5 | $0.00023 | $0.01588 |
| Sonnet 5 | $0.00009 | $0.00635 |
| Haiku 4.5 | $0.00005 | $0.00318 |
Grade A, and why
developer-growth-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Developer Growth Analysis
This skill provides personalized feedback on your recent coding work by analyzing your Claude Code chat interactions and identifying patterns that reveal strengths and areas for growth.
When to Use This Skill
Use this skill when you want to:
- Understand your development patterns and habits from recent work
- Identify specific technical gaps or recurring challenges
- Discover which topics would benefit from deeper study
- Get curated learning resources tailored to your actual work patterns
- Track improvement areas across your recent projects
- Find high-quality articles that directly address the skills you're developing
This skill is ideal for developers who want structured feedback on their growth without waiting for code reviews, and who prefer data-driven insights from their own work history.
What This Skill Does
This skill performs a six-step analysis of your development work:
-
Reads Your Chat History: Accesses your local Claude Code chat history from the past 24-48 hours to understand what you've been working on.
-
Identifies Development Patterns: Analyzes the types of problems you're solving, technologies you're using, challenges you encounter, and how you approach different kinds of tasks.
-
Detects Improvement Areas: Recognizes patterns that suggest skill gaps, repeated struggles, inefficient approaches, or areas where you might benefit from deeper knowledge.
-
Generates a Personalized Report: Creates a comprehensive report showing your work summary, identified improvement areas, and specific recommendations for growth.
-
Finds Learning Resources: Uses HackerNews to curate high-quality articles and discussions directly relevant to your improvement areas, providing you with a reading list tailored to your actual development work.
-
Sends to Your Slack DMs: Automatically delivers the complete report to your own Slack direct messages so you can reference it anytime, anywhere.
How to Use
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

developer-growth-analysis is a skill published in the GitHub repository CommandCodeAI/agent-skills (120 stars, last pushed 5mo ago), licensed MIT. It adds 47 tokens to every session and 3,177 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
