skill-issue-cc 1.3.0

Gamified active learning system for agentic coding sessions

skill-issue

Your AI writes the code. But does your brain keep up?

---

AI coding tools let you ship code you don't understand. Not because you're lazy—there's just no friction. The code looks right, you move on, and slowly you stop reasoning from first principles.

skill-issue tracks what you actually know. When your agent builds something non-trivial, it fires a challenge grounded in what just happened. You answer, it scores you 0-3, and your knowledge graph updates. Next time, it targets concepts you're weak on.

Install

Claude Code

Two separate commands (don't combine them):

/plugin marketplace add SnehalRaj/skill-issue-marketplace

/plugin install skill-issue@skill-issue-marketplace

Open a new session.

pip (Cursor, Codex, any agent)

pip install skill-issue-cc
skill-issue init

Paste the output of skill-issue init --print into your editor's system prompt.

Knowledge Graph

skill-issue graph show --domain machine-learning

Knowledge Graph: machine-learning
============================================================

[GOOD]     gradient-descent       [####..........................] 0.42  (2)
[WEAK]     bias-variance-tradeoff [##............................] 0.09  (1)
[GOOD]     backpropagation        [#############.................] 0.45  (2)
[WEAK]     regularization         [..............................] 0.00
[WEAK]     cross-validation       [..............................] 0.00
[WEAK]     loss-functions         [######........................] 0.21  (1)
[WEAK]     attention-mechanism    [..............................] 0.00

Priority Queue (work on these next):
  >> regularization      (priority: 0.95 = weight:0.95 x gap:1.00)
  >> cross-validation    (priority: 0.95 = weight:0.95 x gap:1.00)
  >> attention-mechanism (priority: 0.95 = weight:0.95 x gap:1.00)

Total nodes: 12 | Avg mastery: 0.10 | 0 mastered | 10 weak

Each domain has a curated graph of concepts weighted by how often they come up in real work.

• reuse_weight (0–1): How fundamental. 0.95 means it's everywhere.
• mastery (0–1): Your proven understanding. Updates via EMA after each challenge.
• priority = weight × (1 - mastery). High-weight stuff you haven't proven = top priority.

Mastery fades if you don't practice (3-day grace, then 0.02/day). Use it or lose it.

Onboarding

skill-issue init

3 questions to personalise your knowledge graph.

1. What do you mainly build or work on?
   > I train ML models and do some backend API work

2. What languages or tools do you use most?
   > Python, PyTorch, FastAPI, PostgreSQL

3. One concept you know you are shaky on? (optional)
   > always forget when cross-validation goes wrong

Knowledge graphs initialised for: machine-learning, backend-systems, algorithms

Three questions, plain English. It figures out which domains to load.

Challenge Types

	Type	What it tests
📝	Pen & Paper	Can you compute this by hand?
🗣️	Explain Back	Can you explain why this works?
🔮	Predict	What does this function return?
🐛	Spot the Bug	Here's a broken version — find it
⏱️	Complexity	What's the Big-O? Can it be better?
🔗	Connect	How does this relate to X?

Challenges are grounded in what was just built. No random trivia.

Commands

Command	What it does
skill-issue init	Onboarding + profile setup
skill-issue stats	XP, level, streak, topic breakdown
skill-issue graph show --domain <d>	ASCII viz
skill-issue graph weak --domain <d>	Top priority nodes
skill-issue graph web --domain <d>	D3 force graph in browser
skill-issue graph domains	List available domains
skill-issue graph update --node <n> --score <0-3> --domain <d>	Update mastery

Voice commands (say to your agent):

Say	Does
my stats / trophy wall	Show profile
show graph / show brain	Visualize knowledge
challenge me	Force a challenge
harder / easier	Shift difficulty ±1
focus mode	Pause challenges
hint / skip	Hint (0.75× XP) / skip

Domains

Domain	Nodes	Covers
machine-learning	12	Gradient descent, backprop, transformers, bias-variance
computer-science	12	Complexity, DP, trees/graphs, concurrency, OS
algorithms	8	Sorting, binary search, DP, graph traversal
quantum-ml	14	Variational circuits, parameter shift, barren plateaus
web-frontend	10	Event loop, closures, promises, DOM, CSS
backend-systems	10	Indexing, ACID, caching, distributed systems
devops	8	Containers, Kubernetes, CI/CD, IaC, GitOps

Add your own in references/knowledge_graphs/.

---

Progression

XP = base × difficulty × streak_multiplier

Score	Meaning	Base XP
0	Wrong / Skipped	0
1	Partial	5
2	Correct	12
3	Exceptional	20

Difficulty multipliers: Apprentice 1× → Practitioner 1.5× → Expert 2× → Master 3×

Streak bonus tops out at 2.5× for consecutive correct answers.

---

Persistent State

Everything's in ~/.skill-issue/. Plain JSON/YAML, no database.

~/.skill-issue/
├── profile.json           # XP, streak, topic levels, milestones
├── config.yaml            # frequency, domains, difficulty bias
├── knowledge_state.json   # per-node mastery for all domains
├── leaderboard.md         # your trophy wall
└── sessions/              # per-session challenge logs
    └── 2026-02-27.json

Version-controllable. Portable. Human-readable.

---

Philosophy

The name's a joke. Claude has skills (literally, .skill files). What about yours?

Understanding compounds. A developer who actually gets the code they ship is more effective long-term. One well-timed challenge beats a passive tutorial. Your trophy wall tracks your growth—no leaderboard against others.
