learn

learn is a command for Claude Code from boparaiamrit/skills-by-amrit. It costs 23 tokens per session (815 once invoked), scanned A, original, MIT.

A command that collects useful lessons from the current coding session and saves them in a project planning file.

In plain words
What is it for?
Use it to record reusable learnings about errors, debugging, architecture, libraries, performance, security, and testing in .planning/LEARNINGS.md.
Why use it?
It prevents fixes, debugging methods, design decisions, and workflow lessons from being lost after the session ends.

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

learn 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 10d 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.

/learn — Extract Session Learnings

Extract reusable patterns and learnings from the current session. Categorize, deduplicate, and persist to .planning/LEARNINGS.md.

Categories

Category What to Capture
Error Resolution Errors encountered and how they were fixed
Debugging Debugging techniques that worked for this codebase
Architecture Architecture decisions, patterns, trade-offs
Tool/Library Tool configs, library quirks, version-specific behavior
Workflow Process improvements, command sequences that helped
Performance Performance fixes, profiling insights, bottlenecks found
Security Security issues found, hardening patterns applied
Testing Test strategies, mocking patterns, coverage insights

Instructions

Step 1: Determine Scope

From $ARGUMENTS:

  • If a category is given: Extract learnings only for that category
  • If all or empty: Scan for learnings across all 8 categories

Step 2: Scan Session Context

Review the current session for extractable learnings:

  1. Errors resolved — What broke and how was it fixed?
  2. Debugging paths — What investigation steps led to root cause?
  3. Architecture choices — What patterns were chosen and why?
  4. Tool discoveries — What tool/library behavior was non-obvious?
  5. Workflow improvements — What process worked well?
  6. Performance insights — What was slow and how was it fixed?
  7. Security findings — What vulnerabilities were found or prevented?
  8. Testing patterns — What test approach worked for this code?

Step 3: Check Existing Learnings

cat .planning/LEARNINGS.md 2>/dev/null || echo "No existing learnings file."

If the file exists, read it to avoid duplicating existing entries.

Step 4: Format Each Learning

Each learning follows this structure:

### [Category] — [Short Title]
- **Pattern:** What was learned (the reusable insight)
- **Context:** Where/when this applies
- **Solution:** The specific fix, technique, or approach
- **Date:** [ISO date]

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.

learn is a command published in the GitHub repository boparaiamrit/skills-by-amrit (5 stars, last pushed 5mo ago), licensed MIT. It adds 23 tokens to every session and 815 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 2026-08-31.
