/wiki-search finds articles and sections that match your keywords. It works at any scale without external dependencies, searching topic names first and then full article content if needed.

How search works

Search uses a two-tier approach to stay fast while still finding deeply buried content: Tier 1 — Index scan: The command reads INDEX.md first and checks topic names and one-line summaries for your keywords. This is usually enough to answer “which topic covers X?” and returns results immediately. Tier 2 — Full article search: If the index scan doesn’t find a match, the command searches across all files in topics/ and concepts/ using a full grep. Results include the matching section heading and surrounding lines so you can see the match in context.

Result format

Found 3 matches for "retention experiments":

### Topics
- **Retention** [coverage: high — 15 sources] — "...D1 experiments in Q1 showed..."
  → wiki/topics/retention.md

- **Experiment Design** [coverage: medium — 4 sources] — "...retention as primary metric..."
  → wiki/topics/experiment-design.md

### Concepts
- **Speed vs Quality Tradeoff** — "...retention impact weighed against..."
  → wiki/concepts/speed-vs-quality.md
Coverage indicators are included in every result so you know how much to trust the wiki excerpt versus reading the raw source files directly:
  • [coverage: high] — 5 or more sources; trust this section
  • [coverage: medium] — 2–4 sources; good overview, check raw files for specifics
  • [coverage: low] — 0–1 sources; read the raw files listed in the article’s Sources section

​
When there are no matches

If nothing is found, the command suggests related topics that might be relevant and recommends next steps:
  • /wiki-query for questions that require connecting multiple topics
  • /wiki-ingest if you think the knowledge should be in the wiki but hasn’t been added yet

When to use /wiki-query instead

/wiki-search is keyword-based — it finds where a term appears. If you want a synthesized answer that draws from multiple topics, use /wiki-query instead. 
# Finding where a topic lives → use /wiki-search
/wiki-search retention

# Getting an answer that connects topics → use /wiki-query
/wiki-query what do we know about retention drop-off after Day 1?
