rag-learning-academy: Skill for Claude Code

.claude/skills/journal/SKILL.md

journal is a skill for Claude Code from TakaGoto/rag-learning-academy. It costs 14 tokens per session (503 once invoked), scanned A, original, MIT.

A lightweight journal for recording what you learned, found confusing, want to revisit, or might build. Each entry is categorized and saved in a Markdown file—a plain-text document with simple formatting.

In plain words
What is it for?
Use it to save insights, questions, confusions, ideas, or general notes in progress/journal.md.
Why use it?
It keeps learning notes in your own words instead of losing them in chat. The notes can also inform later curriculum recommendations.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

journal 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 9d 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.

Journal: Capture Your Thoughts

A lightweight way for learners to jot down what clicked, what confused them, or what they want to revisit. These notes feed back into the curriculum director's recommendations.

Step 1: Get the Entry

If the learner provides text with the command (e.g., /journal embeddings finally make sense — it's just coordinates in meaning space), use that directly.

If no text is provided, prompt: "What's on your mind? Could be something that clicked, something confusing, a question for later, or just a note to yourself."

Step 2: Categorize

Tag the entry with one of these categories based on content:

  • insight — something that clicked or a connection they made
  • confusion — something they don't understand yet
  • question — something they want to explore later
  • idea — a project idea or experiment they want to try
  • note — general observation

Step 3: Save the Entry

Append to progress/journal.md. Create the file if it doesn't exist.

Format:

### [date] — [category]
[their entry text]

Keep their original words. Don't rewrite or polish — this is their voice, their notes.

Step 4: Brief Response

Keep it short. Respond based on the category:

  • insight: Acknowledge it. "Solid mental model. That analogy will serve you well when things get more complex."
  • confusion: Normalize it and offer help. "That's a common sticking point. Want me to /explain [topic] from a different angle?"
  • question: Acknowledge and bookmark. "Good question. We'll hit that in [relevant module]. Or run /explain [topic] now if you're curious."
  • idea: Encourage it. "That's worth trying. When you're ready, /sandbox can help you prototype it."
  • note: Just confirm. "Noted."

Don't turn this into a teaching moment unless they ask. The journal is for them, not for the system.

Suggest next steps if appropriate:

  • /lesson to continue learning
  • /roadmap to check your progress
  • /explain [topic] if a confusion entry points to a specific concept

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.
