description	Find related entries to a seed file, build reading lists, and surface neighbour clusters Marginalia has discovered automatically. Use when the user is browsing rather than asking a specific question.

Discover and curate

Marginalia runs background "tend" passes that mine the corpus for relations: tag overlap, citation graph, semantic neighbours. This skill explains how to surface those relations from the CLI when the user wants to explore rather than search.

When to use

• The user has one file in mind and asks "what else is like this?"
• The user wants to build a reading list around a topic.
• The user asks "what is Marginalia learning about my corpus?"

Prerequisites

• Ingestion has settled (N busy near zero in the prompt). Discovery works against files that already have summaries + tags + sections.
• A few "tend" cycles have run. New corpora have sparse relations until the miners have had a chance to walk the graph.

Workflow

1. Find a seed entry

Either via search:

/search consensus protocols

Or by remembering an entry_id from a prior /info / /discover (tab completion suggests prefixes once they're in this session's cache).

2. Discover related entries

/discover <entry_id>

Output: scored neighbours with a bar chart, sorted by relevance. A * in the leading column flags a direct edge (citation, explicit relation) versus a random-walk-derived neighbour.

/discover <entry_id> --all

By default discovery only returns relations the LLM has vetted. Pass --all when the user wants the raw mining output too — useful for spotting clusters that haven't been quality-gated yet.

3. Drill in

For each neighbour the user finds interesting:

/info <neighbour_entry_id>

The summary + section preview are usually enough to decide whether to read the full file. If yes:

/download <neighbour_entry_id>

4. Trigger a fresh mining pass (optional)

If the user just ingested a lot of new files and wants the relation graph updated immediately:

/tend

This kicks off a maintenance run: mining, vetting, normalization. Returns a tend_run_id and a list of queued tasks. Watch the prompt's N busy count to see when it settles.

/tend <tend_run_id>

Reports the status of that specific run.

Curation patterns

Reading list around a paper

1. /discover <seed_id> — get top-K neighbours.
2. For each that looks promising: /info <neighbour>. Read summary.
3. Note the entry_ids that pass muster. (Tab completion remembers them for the rest of the session.)
4. /download <id> for each, or zip the parent folder if they all live under one tree: /download <folder_id> reading-list.zip.

Mapping a topic

1. /search <broad term> — surfaces top matches.
2. Pick the most central-looking result as a seed.
3. /discover <seed> — branch out one layer.
4. From the discovered set, pick a second seed in a different cluster.
5. Compare the two /discover outputs. Files that show up in both are genuine bridges between the clusters.

Common pitfalls

• Empty discovery results on a new corpus. Mining miners haven't run yet. Either wait for the periodic tick, or run /tend once.

• All neighbours are direct edges. The seed is poorly indexed (short summary, missing tags) so random-walk can't find paths. Re-ingesting (/ingest <path>) re-runs extraction with the current pipeline, which usually fills these in.

• Repeated noise in unvetted results. That's why vetting exists. Drop --all and let the LLM filter.
