learning-science is a skill for Claude Code, Codex from cosmicstack-labs/mercury-agent-skills. It costs 25 tokens per session (527 once invoked), scanned A, original, MIT.

A guide to evidence-based ways of learning, including active recall, spaced repetition, mixing topics, and using words with visuals.

In plain words
What is it for?
Designing study sessions, review schedules, practice activities, explanations, diagrams, and self-testing.
Why use it?
It helps learners remember information for longer instead of relying on repeated reading.

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

learning-science 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 4d 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.

What it actually says

Learning Science

Evidence-based techniques that make learning stick.

Core Techniques

1. Active Recall

What: Test yourself instead of re-reading. Why: Retrieving information strengthens neural pathways.

Instead of re-reading notes → Close the book and summarize from memory.

2. Spaced Repetition

Review Timing
First 1 day
Second 3 days
Third 1 week
Fourth 2 weeks
Fifth 1 month

Tool: Anki or any spaced repetition app.

3. Interleaving

What: Mix different topics in one study session. Why: Forces brain to discriminate between concepts.

Instead of "Chapter 1 problems all day" → Mix Chapter 1, 2, and 3 problems.

4. Dual Coding

What: Combine words and visuals. Why: Two mental representations = stronger memory.

Draw diagrams, mind maps, flowcharts — not just text notes.

5. Elaboration

What: Explain concepts in your own words with examples. Why: Deeper processing creates richer memory traces.

"How would I explain this to a 10-year-old? What's a real-world example?"

Study Session Structure

Pomodoro + Active Recall

25 min focused study (active recall, no passive reading)
5 min break (stand, stretch, hydrate)
25 min active practice (problems, self-test)
5 min break
25 min review/spaced repetition

Metacognition

  • Before studying: What do I already know? What's my goal?
  • During: Am I understanding this? Should I re-read or practice?
  • After: What worked? What was confusing? What should I review tomorrow?

Common Myths

❌ Learning styles (visual/auditory/kinesthetic) are not supported by evidence ❌ Highlighting and re-reading are low-utility techniques ❌ Multitasking impairs learning — single-task ✅ Struggle is part of learning — desirable difficulties

Changes

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.

learning-science is a skill published in the GitHub repository cosmicstack-labs/mercury-agent-skills (471 stars, last pushed 14d ago), licensed MIT. It adds 25 tokens to every session and 527 once invoked, about $0.0001 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 2026-09-03.
