[2.5.3] - 2026-05-28

Features

• qmd get now accepts a :from:count suffix on a path or docid (e.g.
  qmd get "#abc123:120:40" reads 40 lines starting at line 120). Explicit
  --from/-l flags still override the suffix. The MCP get tool accepts the
  same suffix.
• qmd get and qmd multi-get are now line-numbered by default and print
  the document's #docid and qmd:// path in the output header. Disable line
  numbers with --no-line-numbers. The MCP get/multi_get tools default
  lineNumbers to true to match.
• qmd multi-get now includes the #docid in every output format
  (--md, --json, --csv, --xml, --files, and the default CLI view),
  consistent with qmd search.
• qmd get and qmd multi-get accept --full-path, which replaces the
  qmd:// path + #docid with the document's on-disk filesystem path (handy for
  piping into Read/Edit/an editor). Falls back to the canonical qmd:// +
  docid header when the file no longer exists on disk.
• qmd search / qmd query now show a clearer hit identifier: the default CLI
  view (and the new **file:** line in --md output) always prints the full
  qmd://collection/path URI so you can pipe it straight back into qmd get.
• qmd search / qmd query accept --full-path with the same semantics as
  qmd get: the result label becomes the file's on-disk path — ./-prefixed
  relative path when the file lives in a subfolder of $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. Applies to all output formats.
• qmd get and qmd multi-get now also use the ./-prefixed convention when
  --full-path renders a path under $PWD, matching search/query.
• New --format <kind> flag selects the output format (cli | json | csv |
  md | xml | files) for search, query, and multi-get. The legacy
  boolean aliases (--json/--csv/--md/--xml/--files) still work but are
  no longer in --help; prefer --format.

Fixes

• Launcher: source-mode runner selection now prefers Node + tsx over Bun when
  both package-lock.json and bun.lock are present in the package root,
  mirroring the dist-mode "npm priority" rule. Fixes pnpm-global installs that
  copy the entire working tree (including .git and bun.lock) into the
  install dir and previously routed through Bun, causing ABI mismatches with
  the Node-built better-sqlite3 / sqlite-vec native modules.
• Darwin Metal: llama-using commands (query, vsearch, embed) no longer
  dump a multi-kB GGML/Metal backtrace at process exit even when output
  succeeded. The libggml-metal static ggml_metal_device destructor asserts
  [rsets->data count] == 0 during __cxa_finalize_ranges, but the
  buffer-free path never calls the symmetric ggml_metal_device_rsets_rm
  to remove released rsets from the device collection (upstream
  ggml-org/llama.cpp#22593, one-line fix open as PR #22595). The assertion
  only fires when process.exit() skips Node's beforeExit hook, which is
  what node-llama-cpp uses to auto-dispose Metal contexts. Primary fix:
  finishSuccessfulCliCommand now sets process.exitCode = 0 and returns
  instead of calling process.exit(0), so beforeExit fires and the native
  binding cleans up before libc's static destructor runs. Defense-in-depth:
  the launcher (bin/qmd) and the npm test driver (scripts/test-all.mjs
  • the test:bun / test:unit package.json scripts) also set
    GGML_METAL_NO_RESIDENCY=1 on darwin before spawning node/bun, covering
    error paths and tests that still terminate via process.exit(). The env
    var must be set before node/bun start — libggml-metal reads it via libc
    getenv at module-load time, and Bun does not propagate process.env
    mutations to libc setenv — so it lives in the launcher rather than in
    test-preload. Residency sets give no measurable speedup for QMD's
    short-lived CLI workflow (benchmarked on M3 Pro). Opt back in with
    QMD_METAL_KEEP_RESIDENCY=1 for long-lived qmd processes (e.g. the MCP
    daemon may benefit on hot reload) or to triage the upstream fix.
    qmd doctor reports the mitigation state. Minimal reproduction:
    scripts/repro-metal-rsets-crash.mjs.

Docs

• qmd skill: emphasize reading line ranges with get's built-in
  :from:count suffix / --from/-l flags instead of piping through
  sed/head/tail; cite the docid and line numbers now present in retrieval
  output; and author structured intent:/lex:/vec:/hyde: queries yourself
  rather than relying on built-in query expansion.

[2.5.2] - 2026-05-22

Fixes

• Launcher: Rewrite bin/qmd as a Node-based shebang polyglot to fix global npm installation execution failures on Windows (#668 / #452), while supporting seamless fallback to Bun in Node-less environments.

[2.5.1] - 2026-05-20

Changes

• Release: publish from GitHub Actions via npm Trusted Publishing/OIDC instead of a long-lived NPM_TOKEN secret.

[2.5.0] - 2026-05-19

Changes

• Dependencies: update core SQLite/config/chunking packages (better-sqlite3, yaml, web-tree-sitter, tree-sitter-go, and tree-sitter-python) while keeping incompatible zod, tsx, and vitest majors pinned.
• Agent skills: add qmd skills list|get|path to serve version-matched runtime skill instructions from the installed CLI, and make qmd skill install write a stable discovery stub so installed agent skills do not go stale after QMD upgrades.
• CLI: add qmd doctor for index/runtime diagnostics, including SQLite/sqlite-vec versions, embedding fingerprint freshness, mixed-fingerprint detection, safe legacy fingerprint adoption, and content-hash sampling.

Fixes

• Launcher: prefer runnable TypeScript source in git checkouts even when ignored dist/ artifacts exist, while packaged installs continue to run dist/.

• GPU: keep node-llama-cpp's documented gpu: "auto" initialization as the primary path, then perform no-build packaged CUDA/Vulkan/Metal probes only if auto falls back to CPU.

• CLI: move GPU/CPU runtime diagnostics out of qmd status; use qmd doctor for device probing and related environment guidance.

• CLI: point unexpected command/setup failures toward qmd doctor so diagnostics are the default next step when QMD behaves incorrectly.

• Doctor: explicitly warn when content_vectors contains multiple non-empty embedding fingerprint names, with the per-fingerprint document/chunk breakdown.

• Embed: make the TTY progress line label byte-based input progress explicitly, show embedded chunks as a count, and shorten the displayed model name.

• Embed: retain per-chunk failure details, retry failed chunks after later successful embeds and again when no other chunks remain, clear recovered errors, and cap retries to avoid endless loops.

• Tests: expand the container smoke harness to cover npm-global, npx-style, and Bun-global install scenarios, always checking auto and QMD_FORCE_CPU=1 doctor modes, with opt-in tiny qmd embed and GPU probe runs for supported container runtimes.

• Embedding: fingerprint vector metadata using the active embedding model and formatting/chunking parameters so stale vectors are treated as pending after search semantics change. Legacy content_vectors columns are migrated lazily on first vector-health/write use to preserve fast QMD startup.

• Skill: expand the packaged QMD skill with retrieval-first workflows, structured query examples, wiki/source collection guidance, and safe fallbacks when model-backed search is unavailable.

• Tests: make bun run test execute the local unit suite under both Node/Vitest and Bun (test:node + test:bun) so runtime-specific regressions are caught before CI.

• Model config: centralize embedding/rerank/generation model resolution so qmd embed, status, query, vsearch, pull, SDK vector search, and bench use the same active .qmd/index.yaml model hints and environment fallbacks.

• GPU/status: qmd status now uses the same embedding model identity as qmd embed when computing pending embeddings, so URI-backed embeddings are not incorrectly reported as pending under the legacy embeddinggemma alias.

• GPU status: qmd status now always shows GPU mode/configuration without unsafe native probing, and CPU-fallback warnings point to QMD_STATUS_DEVICE_PROBE=1 qmd status for an actual backend probe. The no-GPU warning is emitted once per process instead of once per LLM instance during benchmarks.

• GPU: add QMD_FORCE_CPU=1 / --no-gpu to bypass CUDA/Vulkan/Metal probing entirely, and route native llama.cpp stdout noise to stderr so JSON output stays parseable during search/query commands.

• Snippet line numbers: qmd_query (MCP), HTTP /query, and qmd query
  (CLI JSON output and snippet headers) now return absolute source-file
  line numbers instead of chunk-local ones, so the line field can be
  passed back to qmd_get as fromLine without a separate lookup.
  Snippet selection remains scoped to the best matching chunk
  (preserves #149).

• CLI: qmd query --full now emits the full document body in all output
  formats (json, csv, md, xml), restoring the documented behavior of the
  flag. Previously it returned only the best matching chunk (~3.6KB max
  per result). Output payload for --full queries is now proportional
  to total document size.

• macOS Metal: qmd query --json now flushes successful JSON output and uses a safe immediate-exit path on Darwin to avoid ggml Metal finalizer aborts; other commands still dispose LLM contexts/models before the llama runtime. #368

• Embedding: require complete chunk coverage before treating a document as
  embedded, remove partial vectors when chunk/session failures leave a
  document incomplete, and keep qmd status pending counts honest after
  interrupted long embed runs. #6...

• Embedding: qmd embed -c <collection> now scopes pending-doc selection
  to the requested collection instead of embedding global pending work.
  Scoped --force clears only collection-owned vectors, preserves shared
  hashes referenced by sibling collections, and drops vectors_vec only
  when the scoped clear empties all vectors.

• Hybrid search: weight RRF lists by query type so original FTS and original vector evidence get the intended 2x boost, instead of accidentally boosting the first lexical expansion. #591

• MCP: seed llama.cpp/GGML quiet env vars before launching qmd mcp so native logs cannot pollute stdio JSON-RPC framing. #593

• CLI: remove CommonJS require() calls from ESM index path normalization so qmd --index <path> no longer crashes with ERR_AMBIGUOUS_MODULE_SYNTAX on Node 22+. #634

• Windows CUDA: serialize llama.cpp embedding/reranking contexts by default to avoid intermittent ggml-cuda.cu:98 crashes in qmd query; set QMD_EMBED_PARALLELISM to opt back into parallel contexts if your driver is stable. #519

• MCP: make qmd mcp --index <name> use the selected index for both foreground and daemon HTTP servers instead of falling back to the default store. #343

• Embedding: respect QMD_EMBED_MODEL consistently for vector indexing and vector-backed search, with default-model fallback when unset.

• Config: use one home-directory resolver for YAML config and the default SQLite cache path, avoiding Windows CLI/MCP split-brain when HOME is unset.

• GPU: respect explicit QMD_LLAMA_GPU=metal|vulkan|cuda backend overrides instead of always using auto GPU selection. #529

• Fix: preserve original filename case in handelize(). The previous
  .toLowerCase() call made indexed paths unreachable on case-sensitive
  filesystems (Linux). qmd update automatically migrates legacy
  lowercase paths without re-embedding.

• CLI: make qmd status skip native node-llama-cpp device probing by
  default so status stays safe on machines with broken or unsupported GPU
  drivers. Set QMD_STATUS_DEVICE_PROBE=1 to opt in.

• CLI: lazy-load node-llama-cpp so lightweight commands such as
  qmd status do not import native ML dependencies or trigger llama.cpp
  builds on ARM/no-GPU machines. #491

• Store: keep content rows referenced by inactive documents during orphan
  cleanup so qmd update preserves soft-deleted tombstones for removed
  files. #585

• Packaging: install AST grammar WASM packages as required dependencies so
  Bun global installs include TypeScript/TSX/JavaScript grammars, and add a
  smoke:package-grammars verification command. #595

• Launcher: add wrapper smoke coverage for scoped package, npm/npx,
  Homebrew/Linuxbrew, Bun global symlink layouts, and $BUN_INSTALL
  false-positive runtime selection regressions. #351 #353 #354 #356 #358 #359

[2.1.0] - 2026-04-05

Code files now chunk at function and class boundaries via tree-sitter,
clickable editor links land you at the right line from search results,
and per-collection model configuration means you can point different
collections at different embedding models. 25+ community PRs fix
embedding stability, BM25 accuracy, and cross-platform launcher issues.

Changes

• AST-aware chunking for code files via web-tree-sitter. Supported
  languages: TypeScript/JavaScript, Python, Go, and Rust. Code files
  are chunked at function, class, and import boundaries instead of
  arbitrary text positions. Markdown and unknown file types are unchanged.
  --chunk-strategy <auto|regex> flag on qmd embed and qmd query
  (default regex). SDK: chunkStrategy option on embed() and
  search(). qmd status shows grammar availability.
• qmd bench <fixture.json> command for search quality benchmarks.
  Measures precision@k, recall, MRR, and F1 across BM25, vector, hybrid,
  and full pipeline backends. Ships with an example fixture against
  the eval-docs test collection. #470 (thanks @jmilinovich)
• models: section in index.yml lets you configure embed, rerank,
  and generate model URIs per collection. Resolution order is
  config > env var (QMD_EMBED_MODEL, QMD_RERANK_MODEL,
  QMD_GENERATE_MODEL) > built-in default. #502
  (thanks @JohnRichardEnders)
• CLI search output now emits clickable OSC 8 terminal hyperlinks when
  stdout is a TTY. Links resolve qmd:// paths to absolute filesystem
  paths and open in editors via URI templates (default:
  vscode://file/{path}:{line}:{col}). Configure with QMD_EDITOR_URI
  or editor_uri in the YAML config. #508 (thanks @danmackinlay)
• --no-rerank flag skips the reranking step in qmd query — useful
  when you want fast results or don't have a GPU. Also exposed as
  rerank: false on the MCP query tool. #370 (thanks @mvanhorn),
  #478 (thanks @zestyboy)
• ONNX conversion script for deploying embedding models via
  Transformers.js. #399 (thanks @shreyaskarnik)
• GitHub Actions workflow to build the Nix flake on Linux and macOS.

Fixes

• Embedding: prevent qmd embed from running indefinitely when the
  embedding loop stalls. #458 (thanks @ccc-fff)
• Embedding: truncate oversized text before embedding to prevent GGML
  crash, and bound memory usage during batch embedding. #393
  (thanks @lskun), #395 (thanks @ProgramCaiCai)
• Embedding: set explicit embed context size (default 2048, configurable
  via QMD_EMBED_CONTEXT_SIZE) instead of using the model's full
  window. #500
• Embedding: error on dimension mismatch instead of silently rebuilding
  the vec0 table. #501
• Embedding: handle vec0 OR REPLACE limitation in insertEmbedding.
  #456 (thanks @antonio-mello-ai)
• Embedding: fix model selection when multiple models are configured.
  #494
• BM25: correct field weights to include all 3 FTS columns — title,
  body, and path were not weighted correctly. #462 (thanks @goldsr09)
• BM25: handle hyphenated tokens in FTS5 lex queries so terms like
  "real-time" match correctly. #463 (thanks @goldsr09)
• BM25: preserve underscores in search terms instead of stripping them.
  #404
• BM25: use CTE in searchFTS to prevent query planner regression with
  collection filter.
• Reranker: increase default context size 2048→4096 and make
  configurable via QMD_RERANK_CONTEXT_SIZE. Fix template overhead
  underestimate 200→512. #453 (thanks @builderjarvis)
• GPU: catch initialization failures and fall back to CPU instead of
  crashing.
• MCP: read version from package.json instead of hardcoding. #431
• MCP: include collection name in status output. #416
• Multi-get: support brace expansion patterns in glob matching. #424
• Launcher: prioritize package-lock.json to prevent Bun false
  positive. #385 (thanks @rymalia)
• Launcher: remove $BUN_INSTALL check that caused false Bun detection.
  #362 (thanks @syedair)
• Launcher: skip Git Bash path detection on WSL. #371
  (thanks @oysteinkrog)
• Model cache: respect XDG_CACHE_HOME for model cache directory. #457
  (thanks @antonio-mello-ai)
• SQLite: add macOS Homebrew SQLite support for Bun and restore
  actionable errors. #377 (thanks @serhii12)
• Pin zod to exact 4.2.1 to fix tsc build failure. #382
  (thanks @rymalia)
• Preserve dots and original case in handelize() — filenames like
  MEMORY.md no longer become memory-md. #475 (thanks @alexei-led)
• Include line in --json search output so editor integrations can
  jump directly to file:line. #506 (thanks @danmackinlay)
• Nix: fix paths in flake and make Bun dependency a fixed-output
  derivation so sandboxed Linux builds work offline. #479
  (thanks @surma-dump)
• Sync stale bun.lock (better-sqlite3 11.x → 12.x). CI and release
  script now use --frozen-lockfile to prevent recurrence. #386
  (thanks @Mic92)
• Approve native build scripts in pnpm so better-sqlite3 and
  tree-sitter modules compile correctly. Update vitest ^3.0.0 → ^3.2.4.

[2.0.1] - 2026-03-10

Changes

• qmd skill install copies the packaged QMD skill into
  ~/.claude/commands/ for one-command setup. #355 (thanks @nibzard)

Fixes

• Fix Qwen3-Embedding GGUF filename case — HuggingFace filenames are
  case-sensitive, the lowercase variant returned 404. #349 (thanks @byheaven)
• Resolve symlinked global launcher path so qmd works correctly when
  installed via npm i -g. #352 (thanks @nibzard)

[2.0.0] - 2026-03-10

QMD 2.0 declares a stable library API. The SDK is now the primary interface —
the MCP server is a clean consumer of it, and the source is organized into
src/cli/ and src/mcp/. Also: Node 25 support and a runtime-aware bin wrapper
for bun installs.

Changes

• Stable SDK API with QMDStore interface — search, retrieval, collection/context
  management, indexing, lifecycle
• Unified search(): pass query for auto-expansion or queries for
  pre-expanded lex/vec/hyde — replaces the old query/search/structuredSearch split
• New getDocumentBody(), getDefaultCollectionNames(), Maintenance class
• MCP server rewritten as a clean SDK consumer — zero internal store access
• CLI and MCP organized into src/cli/ and src/mcp/ subdirectories
• Runtime-aware bin/qmd wrapper detects bun vs node to avoid ABI mismatches.
  Closes #319
• better-sqlite3 bumped to ^12.4.5 for Node 25 support. Closes #257
• Utility exports: extractSnippet, addLineNumbers, DEFAULT_MULTI_GET_MAX_BYTES

Fixes

• Remove unused import { resolve } in store.ts that shadowed local export

[1.1.6] - 2026-03-09

QMD can now be used as a library. import { createStore } from '@tobilu/qmd'
gives you the full search and indexing API — hybrid query, BM25, structured
search, collection/context management — without shelling out to the CLI.

Changes

• SDK / library mode: createStore({ dbPath, config }) returns a
  QMDStore with query(), search(), structuredSearch(), get(),
  multiGet(), and collection/context management methods. Supports inline
  config (no files needed) or a YAML config path.
• Package exports: package.json now declares main, types, and
  exports so bundlers and TypeScript resolve @tobilu/qmd correctly.

[1.1.5] - 2026-03-07

Ambiguous queries like "performance" now produce dramatically better results
when the caller knows what they mean. The new intent parameter steers all
five pipeline stages — expansion, strong-signal bypass, chunk selection,
reranking, and snippet extraction — without searching on its own. Design and
original implementation by Ilya Grigorik (@vyalamar) in #180.

Changes

• Intent parameter: optional intent string disambiguates queries across
  the entire search pipeline. Available via CLI (--intent flag or intent:
  line in query documents), MCP (intent field on the query tool), and
  programmatic API. Adapted from PR #180 (thanks @vyalamar).
• Query expansion: when intent is provided, the expansion LLM prompt
  includes Query intent: {intent}, matching the finetune training data
  format for better-aligned expansions.
• Reranking: intent is prepended to the rerank query so Qwen3-Reranker
  scores with domain context.
• Chunk selection: intent terms scored at 0.5× weight alongside query
  terms (1.0×) when selecting the best chunk per document for reranking.
• Snippet extraction: intent terms scored at 0.3× weight to nudge
  snippets toward intent-relevant lines without overriding query anchoring.
• Strong-signal bypass disabled with intent: when intent is provided, the
  BM25 strong-signal shortcut is skipped — the obvious keyword match may not
  be what the caller wants.
• MCP instructions: callers are now guided to provide intent on every
  search call for disambiguation.
• Query document syntax: intent: recognized as a line type. At most one
  per document, cannot appear alone. Grammar updated in docs/SYNTAX.md.

[1.1.2] - 2026-03-07

13 community PRs merged. GPU initialization replaced with node-llama-cpp's
built-in autoAttempt — deleting ~220 lines of manual fallback code and
fixing GPU issues reported across 10+ PRs in one shot. Reranking is faster
through chunk deduplication and a parallelism cap that prevents VRAM
exhaustion.

Changes

• GPU init: use node-llama-cpp's build: "autoAttempt" instead of manual
  GPU backend detection. Automatically tries Metal/CUDA/Vulkan and falls back
  gracefully. #310 (thanks @giladgd — the node-llama-cpp author)
• Query --explain: qmd query --explain exposes retrieval score traces
  — backend scores, per-list RRF contributions, top-rank bonus, reranker
  score, and final blended score. Works in JSON and CLI output. #242
  (thanks @vyalamar)
• Collection ignore patterns: ignore: ["Sessions/**", "*.tmp"] in
  collection config to exclude files from indexing. #304 (thanks @sebkouba)
• Multilingual embeddings: QMD_EMBED_MODEL env var lets you swap in
  models like Qwen3-Embedding for non-English collections. #273 (thanks
  @daocoding)
• Configurable expansion context: QMD_EXPAND_CONTEXT_SIZE env var
  (default 2048) — previously used the model's full 40960-token window,
  wasting VRAM. #313 (thanks @0xble)
• candidateLimit exposed: -C / --candidate-limit flag and MCP
  parameter to tune how many candidates reach the reranker. #255 (thanks
  @pandysp)
• MCP multi-session: HTTP transport now supports multiple concurrent
  client sessions, each with its own server instance. #286 (thanks @joelev)

Fixes

• Reranking performance: cap parallel rerank contexts at 4 to prevent
  VRAM exhaustion on high-core machines. Deduplicate identical chunk texts
  before reranking — same content from different files now shares a single
  reranker call. Cache scores by content hash instead of file path.
• Deactivate stale docs when all files are removed from a collection and
  qmd update is run. #312 (thanks @0xble)
• Handle emoji-only filenames (🐘.md → 1f418.md) instead of crashing.
  #308 (thanks @debugerman)
• Skip unreadable files during indexing (e.g. iCloud-evicted files returning
  EAGAIN) instead of crashing. #253 (thanks @jimmynail)
• Suppress progress bar escape sequences when stderr is not a TTY. #230
  (thanks @dgilperez)
• Emit format-appropriate empty output ([] for JSON, CSV header for CSV,
  etc.) instead of plain text "No results." #228 (thanks @amsminn)
• Correct Windows sqlite-vec package name (sqlite-vec-windows-x64) and add
  sqlite-vec-linux-arm64. #225 (thanks @ilepn)
• Fix claude plugin setup CLI commands in README. #311 (thanks @gi11es)

[1.1.1] - 2026-03-06

Fixes

• Reranker: truncate documents exceeding the 2048-token context window
  instead of silently producing garbage scores. Long chunks (e.g. from
  PDF ingestion) now get a fair ranking.
• Nix: add python3 and cctools to build dependencies. #214 (thanks
  @pcasaretto)

[1.1.0] - 2026-02-20

QMD now speaks in query documents — structured multi-line queries where every line is typed (lex:, vec:, hyde:), combining keyword precision with semantic recall. A single plain query still works exactly as before (it's treated as an implicit expand: and auto-expanded by the LLM). Lex now supports quoted phrases and negation ("C++ performance" -sports -athlete), making intent-aware disambiguation practical. The formal query grammar is documented in docs/SYNTAX.md.

The npm package now uses the standard #!/usr/bin/env node bin convention, replacing the custom bash wrapper. This fixes native module ABI mismatches when installed via bun and works on any platform with node >= 22 on PATH.

Changes

• Query document format: multi-line queries with typed sub-queries (lex:, vec:, hyde:). Plain queries remain the default (expand: implicit, but not written inside the document). First sub-query gets 2× fusion weight — put your strongest signal first. Formal grammar in docs/SYNTAX.md.
• Lex syntax: full BM25 operator support. "exact phrase" for verbatim matching; -term and -"phrase" for exclusions. Essential for disambiguation when a term is overloaded across domains (e.g. performance -sports -athlete).
• expand: shortcut: send a single plain query (or start the document with expand: on its only line) to auto-expand via the local LLM. Query documents themselves are limited to lex, vec, and hyde lines.
• MCP query tool (renamed from structured_search): rewrote the tool description to fully teach AI agents the query document format, lex syntax, and combination strategy. Includes worked examples with intent-aware lex.
• HTTP /query endpoint (renamed from /search; /search kept as silent alias).
• collections array filter: filter by multiple collections in a single query (collections: ["notes", "brain"]). Removed the single collection string param — array only.
• Collection include/exclude: includeByDefault: false hides a collection from all queries unless explicitly named via collections. CLI: qmd collection exclude <name> / qmd collection include <name>.
• Collection update-cmd: attach a shell command that runs before every qmd update (e.g. git stash && git pull --rebase --ff-only && git stash pop). CLI: qmd collection update-cmd <name> '<cmd>'.
• qmd status tips: shows actionable tips when collections lack context descriptions or update commands.
• qmd collection subcommands: show, update-cmd, include, exclude. Bare qmd collection now prints help.
• Packaging: replaced custom bash wrapper with standard #!/usr/bin/env node shebang on dist/qmd.js. Fixes native module ABI mismatches when installed via bun, and works on any platform where node >= 22 is on PATH.
• Removed MCP tools search, vector_search, deep_search — all superseded by query.
• Removed qmd context check command.
• CLI timing: each LLM step (expand, embed, rerank) prints elapsed time inline (Expanding query... (4.2s)).

Fixes

• qmd collection list shows [excluded] tag for collections with includeByDefault: false.
• Default searches now respect includeByDefault — excluded collections are skipped unless explicitly named.
• Fix main module detection when installed globally via npm/bun (symlink resolution).
