About this skill
QMD - Query Markdown Documents
How search works
QMD searches local markdown collections: notes, docs, wikis, transcripts, and project knowledge bases. Use it before web search when the answer may already be in indexed local files.
The workflow is always:
- Search for candidate documents.
- Retrieve the full source with
qmd getorqmd multi-get. - Answer from retrieved text, citing paths or docids.
Do not answer from snippets alone when the user needs facts, decisions, quotes, or nuance. Snippets are only leads.
Typical loop:
qmd search "merchant reality support interviews" -n 5
# leads: #abc123 concepts/customer-proximity.md; #def432 sources/merchant-call.md
qmd multi-get "#abc123,#def432" --format md
Default to structured qmd query with intent:, lex:, vec:, and hyde:
fields that you write yourself. You are a better query expander than the
built-in model: you know the user's actual goal, the domain vocabulary, and the
nearby-but-wrong concepts to avoid. Do not just paste the user's words into
qmd query "..." and hope the expansion model guesses right — supply the
intent: and craft the lexical and semantic terms deliberately (see
Pick the right search mode).
When reporting what you retrieved, a compact note is enough; do not paste whole files unless needed:
Retrieved:
- #abc123 concepts/customer-proximity.md
- #def432 sources/merchant-call.md
Pick the right search mode
Use BM25 lexical search when you know exact words, titles, names, code symbols, or rare phrases:
qmd search "cockpit OKR Goodhart" -n 10
qmd search '"AI Before Headcount"' -c concepts -n 5
Use qmd query with structured fields when the user describes an idea
indirectly, uses different wording than the source, or needs conceptual recall.
This is the default mode — write the fields yourself rather than leaning on
query expansion. Combine exact anchors with semantic recall:
qmd query $'intent: Find the concept note about metrics as instruments without letting OKRs replace judgment.\nlex: cockpit instruments OKR Goodhart metrics judgment\nvec: data informed not metric driven product judgment\nhyde: A concept note says metrics are useful like cockpit instruments, but leaders should remain data-informed rather than metric-driven because OKRs and dashboards can Goodhart product judgment.'
Structured query fields (you author each one — do not delegate this to the expansion model):
intent:states what you are trying to find and what to avoid. Always supply this. It steers ranking away from nearby-but-wrong concepts.lex:exact terms, aliases, titles, code symbols, and rare words you expect in the source. This is your own keyword expansion.vec:paraphrases the idea in natural language, in source-like wording.hyde:describes the document or answer that would satisfy the request.
You do not need all four every time, but you should almost always write at least
intent: plus one of lex:/vec:. A bare qmd query "the user's sentence"
throws away the context only you have and relies on the built-in expander to
reconstruct it — prefer the structured form.
If you genuinely have nothing to expand (a single rare token, a verbatim phrase),
that is a job for qmd search, not bare qmd query:
qmd query --format json --explain $'intent: ...\nlex: ...\nvec: ...' # inspect ranking
If qmd query is slow or model/GPU setup fails, fall back to qmd search with
better lexical terms.
Retrieve sources
Search results include docids like #abc123 and qmd://... paths. Fetch them:
qmd get "#abc123"
qmd get qmd://concepts/ai-before-headcount.md
qmd multi-get "#abc123,#def432" --format md
qmd multi-get 'concepts/{ai-before-headcount.md,data-informed-not-metric-driven.md}' --format md
qmd multi-get 'sources/podcast-2025-*.md' -l 80
Use multi-get when comparing several hits or gathering context across pages.
Output is line-numbered and carries the docid — cite both
get and multi-get are line-numbered by default and always print the
document's #docid and qmd:// path. So get output looks like:
qmd://concepts/note.md #abc123
---
1: # Metrics as instruments
2:
3: Treat dashboards like cockpit instruments...
Cite the docid and exact line numbers in your answer, and use the numbers to ask
for the next slice. Pass --no-line-numbers only when you need raw content to
copy verbatim (e.g. reproducing a code block).
When you need to open or edit the underlying file (e.g. hand a path to Read,
Edit, or an editor), add --full-path. It replaces the qmd:// URL + docid
header with the document's on-disk path, falling back to the canonical header if
the file no longer exists on disk:
$ qmd get "#abc123" --full-path
/Users/you/notes/concepts/note.md
---
1: # Metrics as instruments
--full-path works the same way on qmd search and qmd query: result paths
become the file's on-disk path — ./-prefixed relative path when the file is
inside $PWD, absolute realpath otherwise — and the per-result #docid is
dropped because the path is the identifier. The leading ./ is intentional so
the output is unambiguously a filesystem path and cannot be mistaken for a bare
collection-relative string. Default search/query output still uses qmd://
URIs; only opt into --full-path when you specifically need a path you can hand
to a non-QMD tool.
Read line ranges with the :from:count suffix — never pipe through sed/head/tail
qmd get slices files itself. Use the suffix or flags; do not shell out to
sed -n, head, tail, or awk to pull a line range. Piping defeats docid
resolution, virtual-path lookups, line numbering, and the header, and it is
slower and more error-prone.
The most compact form is a :from:count suffix right on the path or docid —
prefer it:
qmd get "#abc123:120:40" # 40 lines starting at line 120
qmd get qmd://concepts/note.md:200:60 # lines 200–259
qmd get "#abc123:120" # from line 120 to end of file
qmd get "#abc123" --from 120 -l 40 # equivalent, using flags
Suffix and flags:
<path>:<from>:<count>— start at line<from>, read<count>lines. Best for reading around a search hit.<path>:<from>— start at<from>, read to end of file.--from <line>/-l <lines>— flag equivalents. Explicit flags override the suffix, so... :5:2 -l 1reads 1 line.--no-line-numbers— drop theN:prefixes (line numbers are on by default).
Wrong: qmd get "#abc123" | sed -n '120,160p'
Right: qmd get "#abc123:120:40"
Search results include a :line anchor on each hit — feed it straight into
qmd get path:line:<n> to read a window around the match (line numbers in the
output will start at line).
Discover what is indexed
qmd collection list
qmd ls
qmd status
Add collection filters when broad searches drift into the wrong corpus:
qmd search "headcount autonomous agents" -c concepts -n 10
qmd query "merchant support product reality" -c concepts -c sources -n 10
Omit -c to search everything.
MCP Tool: query
When using the MCP server, prefer structured searches:
{
"searches": [
{ "type": "lex", "query": "cockpit OKR Goodhart" },
{ "type": "vec", "query": "data informed not metric driven product judgment" },
{ "type": "hyde", "query": "A concept note explains that metrics are useful as instruments, but leaders should not let OKRs or dashboards replace judgment." }
],
"intent": "Find the concept note about using metrics as instruments without becoming metric-driven.",
"collections": ["concepts"],
"limit": 10
}
Query types:
lex— BM25 keyword search. Best for exact terms, names, titles, and code.vec— vector semantic search. Best for natural-language concepts.hyde— vector search using a hypothetical answer/document passage.
Query craft
Good QMD searches mix three things:
- Title/alias anchors: exact page titles, named entities, phrases.
- Semantic paraphrase: how a human would describe the idea.
- Negative space: enough intent to avoid nearby-but-wrong concepts.
Examples:
# Exact-ish title lookup
qmd search '"arm the rebels" merchants tools big companies' -c concepts
# Semantic concept lookup
qmd query $'intent: Find the customer proximity concept, not generic customer delight.\nlex: support pseudonymous merchant customer interviews\nvec: founder stays close to merchant reality through support and product use'
# Source lookup
qmd search "six-week cadence WhatsApp merchant relationships Shawn Ryan" -c sources -n 10
Setup and maintenance
Only mutate indexes when the user asked for setup or maintenance. Searching and retrieving are safe; collection/index mutation is not a casual first step.
npm install -g @tobilu/qmd
qmd collection add ~/notes --name notes
qmd update
qmd embed
Health and diagnostics:
qmd doctor
qmd status
qmd pull
qmd doctor checks config, model cache, device/GPU setup, vector fingerprints,
and common environment overrides. If a model-backed command fails, run it before
changing configuration.
MCP setup
See references/mcp-setup.md for Claude Code, Claude Desktop, OpenClaw, and HTTP
server configuration.
Pitfalls
- Do not stop at snippets. Fetch documents before making claims.
- Do not slice files with
sed/head/tail. Use thepath:from:countsuffix (e.g.qmd get "#abc123:120:40") or--from/-l. Output is already line-numbered; piping breaks docid resolution, the header, and virtual paths. - Do not lean on query expansion. Write
intent:/lex:/vec:/hyde:yourself. A bareqmd query "user sentence"discards the context only you have. You expand the query; the model just ranks. - **Do not overuse
Content truncated.
When not to use it
- →When performing casual index mutations without explicit user request
- →When piping search results through external shell utilities like sed or head
Prerequisites
Limitations
- →Requires manual authoring of structured query fields for optimal results
- →Model-backed commands may fail if local GPU or environment configuration is missing
