At a glance

Runs an interactive quiz in a quick or comprehensive mode, scores your skill level by topic and generates a personalized learning path with practice projects.

Works in 4 steps: Choose Your Mode → Answer Questions → Get Your Profile → …
Finding out your current level with an AI coding agent
SKILL.md covers How It Works, Getting Started, What You Learn and After Your Assessment, plus 3 more sections
Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

The skill offers two modes: a quick check with 10 questions across 10 topics that returns an overall profile (Beginner, Intermediate or Advanced) and the top two or three gaps, and a comprehensive mode with 20 questions, two per topic, that gives per-topic scores, a detailed learning path and 3 practice projects.

Questions cover practical usage, decision-making, architecture patterns and production practices. Each has four options, immediate feedback on the correct answer and a link to the matching guide section. The learning path orders topics by weakness and importance, shows prerequisites, gives time estimates and links templates and examples. It is started with /self-assessment quick or /self-assessment comprehensive, and a verbose option shows explanations.

When your agent uses it

Finding out your current level with an AI coding agent
Planning team training with a per-topic skill breakdown
Getting a prioritized learning path with practice exercises

Example prompts

“/self-assessment quick”
“Run the comprehensive self-assessment and give me a learning path for my weakest topics.”
“Do a quick assessment with explanations after each answer.”

What it can do on your machine

Read from SKILL.md and the folder at commit 585c203. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Codex Skill Self-Assessment loads about 2.3k tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 538 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~22
When it runs · the whole SKILL.md, loaded when a task matches: ~2.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
