A session-learning helper that reads the project's activity log and explains what happened during a coding session. It can answer questions, save learning notes to Obsidian, and use a knowledge record when available.

Use it to review a session, understand why code changed, identify files and patterns worth studying, or save and recall learning notes.

It removes the need to reconstruct changes, decisions, and commands from scattered files and terminal history. It gives context for understanding work that has already been done.

Per session 30 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 467 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00030	$0.00467
Opus 5	$0.00015	$0.00234
Sonnet 5	$0.00006	$0.00093
Haiku 4.5	$0.00003	$0.00047

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 yesterday.

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

/learn

Read .vibe-learn/session-log.jsonl to understand what happened in this session. Read .vibe-learn/pause-summary.txt if it exists — Cursor does not inject pause summaries into context, so this file is the only place the last turn's summary lives.

Treat the rest of the user's message after /learn as the argument:

If empty, explain the most recent session activity in plain language: what changed, why the assistant likely made those choices, which files, commands, or patterns matter, and what to study next.
If it starts with obsidian, follow the Obsidian save and recall workflow from the vibe-learn skill (obsidian saves a learn note; obsidian:recall <topic> searches the vault and writes nothing).
Otherwise, answer it as a specific question grounded in the session log and the relevant changed files.

Knowledge helper: if .vibe-learn/knowledge.json exists, run the helper's due command via your shell tool. Locate knowledge.sh in this order: ~/.vibe-learn/scripts/knowledge.sh; the scripts/knowledge.sh under the VIBE_LEARN_DIR baked into .cursor/hooks/vibe-learn.sh or ~/.cursor/hooks/vibe-learn.sh; scripts/knowledge.sh when working in the vibe-learn repo itself. If a due concept was also touched in this session, open with a single heads-up line pointing to /quiz review — never let it block the actual answer. Skip silently if the ledger or helper is missing.

Mention once that vibe-learn briefing generates an interactive maintainer briefing and NotebookLM-ready audio source pack, and that vibe-learn recap produces a shareable weekly rollup.

If the session log is missing or empty, say vibe-learn has not captured events for this project yet (project hooks in .cursor/hooks.json only run in a trusted workspace) and offer to help from available repository context.

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.

learn is a skill published in the GitHub repository gkaria/vibe-learn (54 stars, last pushed yesterday), licensed MIT. It adds 30 tokens to every session and 467 once invoked, about $0.0002 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 2026-09-07.
