description: Generate a structured vibe-learn learning digest of the current coding session from .vibe-learn/session-log.jsonl.
---

<!-- vibe-learn copilot-cli adapter -->

# /digest

Read `.vibe-learn/session-log.jsonl` and any relevant source files touched during the session. Read `.vibe-learn/pause-summary.txt` if it exists.

**Briefing (all modes):** before anything else, refresh the session briefing: run `vibe-learn briefing --if-stale` via your shell tool. If `vibe-learn` is not on PATH, run `bash <dir>/briefing.sh --if-stale`, where `<dir>` is the directory that holds vibe-learn's `knowledge.sh` (`scripts/` in a full install, the hooks directory in a techpack install) (found with the knowledge-helper lookup; `~/.vibe-learn/scripts/` for a global install). It returns at once when the briefing is current. Skip it silently if neither exists, and do not mention its output unless it fails.

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

- If empty, generate a structured session digest.
- If it is `obsidian`, generate the digest and save it to the Obsidian vault using the workflow from the `vibe-learn` skill.
- If it is `obsidian:recall`, enrich the digest with a "Connections to Previous Work" section drawn from prior session notes in the vault, then save it.

Digest format:

## Session Digest

### What Was Built

### Key Decisions

### Patterns Used

### Files And Commands Worth Reviewing

### Things To Study Next

If `.vibe-learn/knowledge.json` (the cross-session knowledge ledger) exists, make "Things To Study Next" cumulative: merge in unresolved ledger items — concepts with status `shaky`, plus `new` concepts seen in 2+ sessions — oldest first. Mention `/quiz review` when shaky items appear.

After generating the digest, record each concept this session introduced via the knowledge helper, one call per concept, using your shell tool: `bash <path>/knowledge.sh touch <kebab-case-name> --label="<Human label>"`. Locate `knowledge.sh` in this order: `~/.vibe-learn/scripts/knowledge.sh`; read `.github/hooks/vibe-learn.json` (then `${COPILOT_HOME:-$HOME/.copilot}/hooks/vibe-learn.json`) and extract the first non-empty `.hooks[][] | .env.VIBE_LEARN_INSTALL_DIR` value, then append `/scripts/knowledge.sh`; `scripts/knowledge.sh` when working in the vibe-learn repo itself. Never hand-edit the JSON. Skip silently if the helper is missing.

Offer to save the digest to `.vibe-learn/digests/` as a markdown file. Also mention that `vibe-learn briefing` creates an interactive maintainer briefing and NotebookLM-ready audio source pack.

**First digest nudge:** if `.vibe-learn/digests/` does not exist yet, this is the first digest for this project. After the save offer, add exactly one closing line: "That's your first digest here. If vibe-learn is helping, a star at https://github.com/gkaria/vibe-learn helps others find it." Never repeat it once the folder exists.

If the session log is missing or empty, say vibe-learn has not captured events for this project yet and offer to help from available repository context.
