-name: lancedb-branch-ops
-description: Branch management for LanceDB tables via the REST API. Use this skill whenever someone wants to create, delete, list, or switch branches on a LanceDB table — or needs to make sure a write (metadata update, index build, etc.) lands on a specific branch instead of main. Invoke it even without the word "branch" if context makes clear they want an experimental copy of a table, want to isolate changes, or want to confirm a mutation didn't touch main. Covers: branches/list, branches/create, branches/delete, and passing "branch" in describe/update_field_metadata/create_index to target a non-main version.
---
-
-## Goal
-
-Manage branches on a LanceDB table: list what exists, create new ones, delete stale ones, and direct read/write operations at a specific branch without touching main.
-
-## Step 0: Establish the connection
-
-Use the `lancedb-connect` skill to resolve the base URL and auth headers (`x-api-key`, `x-lancedb-database`). Skip this only if the connection is already known from the current conversation.
-
-All examples below use `{base_url}` — substitute the resolved endpoint and include the auth headers on every request.
-
-## The branch model (important)
-
-LanceDB branches are named snapshots that diverge from the table's current state at creation time. There is **no checkout command** — you never switch the whole table to a branch. Instead, you **pass `"branch": "<name>"` in the request body** of any operation to target that branch. Omitting the key (or sending an empty body) always targets main.
-
-`branches/list` returns only non-main branches. Main always exists and is not listed.
-
-## List branches
-
-```http
-POST {base_url}/v1/table/{table_id}/branches/list
-Content-Type: application/json
-
-{}
-```
-
-Response:
-```json
-{
-  "branches": {
-    "experiment-reindex": {"parentVersion": 1, "createAt": 1782506085, "manifestSize": 1029}
-  }
-}
-```
-
-If `branches` is `{}`, the table has no branches besides main.
-
-## Create a branch
-
-```http
-POST {base_url}/v1/table/{table_id}/branches/create
-Content-Type: application/json
-
-{"name": "experiment-reindex"}
-```
-
-HTTP 200 with `{}` body = success. The branch is created off the table's current state on main.
-
-Verify by calling `branches/list` and confirming the new name appears.
-
-## Delete a branch
-
-```http
-POST {base_url}/v1/table/{table_id}/branches/delete
-Content-Type: application/json
-
-{"name": "stale-2024"}
-```
-
-HTTP 200 with `{}` body = success. Only the branch pointer is removed — main and all row data remain intact.
-
-Verify by calling `branches/list` (name gone) and `describe` with no branch param (main still responds).
-
-## Operate on a specific branch
-
-Pass `"branch": "<name>"` in the body of any operation to scope it to that branch:
-
-**Read schema on a branch:**
-```http
-POST {base_url}/v1/table/{table_id}/describe
-Content-Type: application/json
-
-{"branch": "wip-branch"}
-```
-
-**Write metadata to a branch (not main):**
-```http
-POST {base_url}/v1/table/{table_id}/update_field_metadata
-Content-Type: application/json
-
-{
-  "branch": "wip-branch",
-  "updates": [
-    {
-      "path": "category",
-      "metadata": {"lancedb:description": "Product category label."},
-      "replace": false
-    }
-  ]
-}
-```
-
-**Build an index on a branch:**
-```http
-POST {base_url}/v1/table/{table_id}/create_index
-Content-Type: application/json
-
-{
-  "branch": "wip-branch",
-  "column": "category",
-  "index_type": "BTREE"
-}
-```
-
-## Verifying isolation
-
-After writing to a branch, always confirm the change did NOT land on main:
-
-```bash
-# Should show the new metadata
-curl -s -X POST {base_url}/v1/table/{table_id}/describe \
-  -H "x-api-key: <key>" -H "x-lancedb-database: <db>" \
-  -H "content-type: application/json" \
-  -d '{"branch": "wip-branch"}'
-
-# Should NOT show the new metadata
-curl -s -X POST {base_url}/v1/table/{table_id}/describe \
-  -H "x-api-key: <key>" -H "x-lancedb-database: <db>" \
-  -H "content-type: application/json" \
-  -d '{}'
-```
-
-## Quick reference
-
-| Goal | Endpoint | Body |
-|------|----------|------|
-| List all branches | `branches/list` | `{}` |
-| Create a branch | `branches/create` | `{"name": "..."}` |
-| Delete a branch | `branches/delete` | `{"name": "..."}` |
-| Read schema on branch | `describe` | `{"branch": "..."}` |
-| Write metadata on branch | `update_field_metadata` | `{"branch": "...", "updates": [...]}` |
-| Build index on branch | `create_index` | `{"branch": "...", "column": ..., "index_type": ...}` |

-name: lancedb-column-metadata
-description: Column metadata authoring for LanceDB tables via the REST API. This skill is required for tasks like writing field descriptions, setting tags on columns (field_type, model, project_id, version), classifying columns as embeddings vs labels vs eval metrics, or grouping versioned columns into logical families — because it has the API integration needed to read the schema and persist metadata back. Invoke whenever someone wants to document, annotate, tag, or classify what their table columns ARE. Trigger even without an explicit "LanceDB" mention, as long as the context is column-level documentation or tagging for an ML or vector database table.
-metadata:
-  short-description: Write column descriptions, tags, and logical groupings to a LanceDB table
---
-
-## Overview
-
-This skill authors column-level metadata for a LanceDB table. It connects to a LanceDB deployment over its REST API, inspects the table schema, generates appropriate metadata, and writes it back.
-
-## Step 0: Establish the connection
-
-Use the `lancedb-connect` skill (invoke it via the Skill tool) to resolve the base URL and auth headers (`x-api-key`, `x-lancedb-database`) for whichever deployment the user is working against — enterprise/self-hosted or a local dev server. Skip it only if the connection details are already established in the conversation.
-
-All examples below use `{base_url}` — substitute the resolved endpoint and include the resolved headers on every request.
-
-## Metadata keys
-
-All metadata uses namespaced keys:
-
-| Key | Purpose | Example value |
-|-----|---------|---------------|
-| `lancedb:description` | Human-readable explanation of what the column contains | `"CLIP ViT-L/14 image embedding, L2-normalized (768-dim)"` |
-| `lancedb:tag:<name>` | Flexible key-value tag; the suffix names the tag category | `lancedb:tag:field_type: "embedding"`, `lancedb:tag:model: "clip"`, `lancedb:tag:project_id: "foo"` |
-| `lancedb:logical-column` | Logical group/family this column belongs to | `"clip_features"` |
-
-Tags are open-ended — use whatever key suffix and value make sense given the user's intent. The tag suffix should describe *what is being classified* (e.g., `field_type`, `model`, `project_id`) and the value describes *how*.
-
-## Step 1: Resolve the table identifier
-
-You need:
- **Table name** (required) — e.g., `my_table` or `my_namespace.my_table`
- **Database name** — ask if not provided and not inferable from context; it goes in the `x-lancedb-database` header, never in the URL path
-
-The table identifier in the URL path is typically `table_name` for a top-level table, or `namespace$table_name` if the table lives in a namespace. The API accepts a `delimiter` query parameter to parse compound identifiers (default `$`).
-
-## Step 2: Describe the table
-
-```http
-POST {base_url}/v1/table/{table_id}/describe
-Content-Type: application/json
-
-{}
-```
-
-The response contains `schema.fields` — an array of field objects:
-
-```json
-{
-  "schema": {
-    "fields": [
-      {
-        "name": "clip_embedding_v3",
-        "type": { "type": "FixedSizeList", "fields": [...], "listSize": 768 },
-        "nullable": true,
-        "metadata": { "lancedb:description": "..." }
-      }
-    ]
-  }
-}
-```
-
-Each field has:
- `name` — field name
- `type` — Arrow data type (check `type.type` for the type string)
- `nullable` — boolean
- `metadata` — existing key-value metadata (read this before writing to avoid redundant updates)
-
-For struct/nested fields, recurse into `type.fields` and represent them as dot-notation paths (e.g., `parent.child`).
-
-If the user hasn't specified which columns to update, work with all columns.
-
-## Step 3: Generate metadata
-
-Decide what to generate based on the user's request.
-
-### Writing descriptions (`lancedb:description`)
-
-Base descriptions on:
- The column name and Arrow type (e.g., `FixedSizeList` of floats → likely an embedding)
- User-supplied context (upstream pipeline, sample values, domain knowledge)
- Name patterns: `_embedding`/`_vec`/`_embed` → vector; `_label`/`_class` → label; `_score`/`_eval`/`_metric` → evaluation metric
-
-Be specific and concise. Good: `"Sentence-BERT embedding of the query text (768-dim)."` Not: `"An embedding column."`
-
-### Tagging columns (`lancedb:tag:<name>`)
-
-Choose tag key names that match what the user asked to annotate. Common patterns:
-
- Semantic field type → `lancedb:tag:field_type: "embedding"` / `"text"` / `"image"` / `"label"` / `"eval"` / `"id"` / `"metadata"`
- Model or source → `lancedb:tag:model: "clip"` / `"bert"` / `"vit"`
- Project affiliation → `lancedb:tag:project_id: "<name>"`
- Version → `lancedb:tag:version: "v3"` (and `lancedb:tag:latest: "true"` for the newest)
-
-Use Arrow type as a hint: `FixedSizeList` + float → embedding; `Utf8`/`LargeUtf8` → text; `Binary` → image or blob.
-
-Multiple tags on the same column are fine — each is a separate key.
-
-### Grouping into logical columns (`lancedb:logical-column`)
-
-Look for naming patterns across columns:
- `clip_v1`, `clip_v2`, `clip_v3` → logical column `"clip"`, latest is `v3`
- `text_embed_20240101`, `text_embed_20240601` → logical column `"text_embed"`, latest is the most recent date suffix
-
-Write `lancedb:logical-column` on all members of a group. Mark the newest with `lancedb:tag:latest: "true"` (in addition to its version tag).
-
-## Step 4: Write the metadata
-
-```http
-POST {base_url}/v1/table/{table_id}/update_field_metadata
-Content-Type: application/json
-
-{
-  "updates": [
-    {
-      "path": "clip_v3",
-      "metadata": {
-        "lancedb:description": "CLIP ViT-L/14 image embedding, L2-normalized (1024-dim).",
-        "lancedb:tag:field_type": "embedding",
-        "lancedb:tag:model": "clip",
-        "lancedb:tag:version": "v3",
-        "lancedb:tag:latest": "true",
-        "lancedb:logical-column": "clip"
-      },
-      "replace": false
-    },
-    {
-      "path": "clip_v2",
-      "metadata": {
-        "lancedb:description": "CLIP ViT-B/32 image embedding (768-dim), superseded by v3.",
-        "lancedb:tag:field_type": "embedding",
-        "lancedb:tag:model": "clip",
-        "lancedb:tag:version": "v2",
-        "lancedb:logical-column": "clip"
-      },
-      "replace": false
-    }
-  ]
-}
-```
-
-Rules:
- **Use `"replace": false`** (merge) by default — this preserves existing metadata the user didn't ask to change
- Use `"replace": true` only if the user explicitly asks to overwrite all existing metadata on a column
- Set a value to `null` to delete a specific key
- Batch all updates in a single request when possible
-
-The response includes `version` (new table version) and `fields` (the updated metadata per field).
-
-## Step 5: Confirm
-
-Report back:
- Which columns were updated and what was written
- The new table version number
- Any columns skipped (e.g., already had up-to-date metadata)
-

-## Quick examples
-
-**"Write descriptions for all columns in the `product_embeddings` table"**
-1. POST `/v1/table/product_embeddings/describe` → get all fields
-2. Generate a `lancedb:description` for each column based on name + type
-3. POST `update_field_metadata` with descriptions
-4. Report
-
-**"Tag the columns in `model_outputs` with their field type and model"**
-1. Describe `model_outputs`
-2. For each field, classify by name + Arrow type → set `lancedb:tag:field_type` and `lancedb:tag:model` where applicable
-3. POST `update_field_metadata`
-4. Report
-
-**"Group the feature columns in `training_features` into logical families and mark the latest version"**
-1. Describe the table
-2. Find version patterns → assign `lancedb:logical-column` and `lancedb:tag:version`; mark newest with `lancedb:tag:latest: "true"`
-3. POST `update_field_metadata`
-4. Show the grouping

-name: lancedb-connect
-description: Resolve how to connect to a LanceDB deployment over the REST API — figure out the base URL, API key, and database header. Use this before making any REST requests to a LanceDB table, whenever the endpoint or auth setup is not already known. Also useful on its own when someone asks how to connect, authenticate, or curl their LanceDB instance.
-metadata:
-  short-description: Resolve the base URL and auth headers for a LanceDB deployment
---
-
-## Goal
-
-Produce two things every REST request needs:
-
-1. **Base URL** — the endpoint
-2. **Headers** — `x-api-key`, and usually `x-lancedb-database`
-
-## Resolution steps
-
-1. If the user already gave a URL and API key (or said which environment they're working against), use that.
-2. Otherwise, look for credentials already available in the environment:
-   - Env vars like `LANCEDB_URI` / `LANCEDB_HOST` / `LANCEDB_API_KEY`
-   - A LanceDB endpoint already running or port-forwarded locally (the REST default port is 2333, i.e. `http://localhost:2333`)
-3. If you didn't find both pieces, ask the user directly: **"What's your LanceDB endpoint's URL, and what's your API key?"** Also ask which database to use if it isn't obvious. Don't guess or probe further — the user knows their deployment.
-
-## Validating the connection
-
-Make a cheap authenticated request and check the status:
-
-```bash
-curl -s -w "\n%{http_code}" "{base_url}/v1/table/?limit=1" \
-  -H "x-api-key: <key>" \
-  -H "x-lancedb-database: <database>"
-```
-
- `200` — connection, key, and database header all good
- `401` — API key missing or wrong
- `400` mentioning a database header — this deployment expects `x-lancedb-database`
-
-## Non-REST equivalents
-
-If the caller would rather use the SDK or CLI than raw REST, the same credentials work:
-
- Python SDK: `lancedb.connect("db://<database>", api_key="<key>", host_override="<base_url>")`
- `lancedb` CLI: a `[profiles.<name>]` entry in `~/.lancedb/config.toml` with `http_server_url`, `api_key`, `database`

-name: lancedb-update-lance-dependency
-description: Update LanceDB to a specific Lance release or tag. Use when bumping Lance dependencies in the lancedb repository, including Rust workspace Lance crates, Java lance-core, validation, branch creation, commit, push, and PR creation when requested.
---
-
-# LanceDB Update Lance Dependency
-
-## Scope
-
-Use this skill in the `lancedb/lancedb` repository when updating the Lance dependency to a specific Lance version or tag.
-
-Inputs can be a version (`7.2.0-beta.1`), a tag (`v7.2.0-beta.1`), a tag ref (`refs/tags/v7.2.0-beta.1`), or `latest`.
-
-## Workflow
-
-1. Confirm the worktree status with `git status --short`.
-2. Resolve the target Lance version:
-
-   - If the input is `latest`, empty, or omitted, run:
-
-     ```bash
-     python3 ci/check_lance_release.py
-     ```
-
-     Parse the JSON output. If `needs_update` is not `true`, stop without creating a PR. Otherwise use `latest_tag`.
-
-   - If the input is explicit, use it directly.
-
-3. Compute update metadata without changing files:
-
-   ```bash
-   python3 ci/update_lance_dependency.py "$TAG_OR_VERSION" --metadata-only
-   ```
-
-   Before making changes, check for an existing open PR with the emitted `pr_title`:
-
-   ```bash
-   gh pr list --search "\"$PR_TITLE\" in:title" --state open --limit 1 --json number,url,title
-   ```
-
-   If a matching open PR exists, stop and report it instead of creating a duplicate.
-
-4. Run the deterministic update entrypoint:
-
-   ```bash
-   python3 ci/update_lance_dependency.py "$TAG_OR_VERSION"
-   ```
-
-   This updates the Rust workspace Lance dependencies through `ci/set_lance_version.py`, updates `java/pom.xml`, refreshes Cargo metadata, and prints JSON metadata containing `branch_name`, `commit_message`, and `pr_title`.
-
-5. Run validation:
-
-   ```bash
-   cargo clippy --quiet --workspace --tests --all-features -- -D warnings
-   cargo fmt --all --quiet
-   ```
-
-   Fix real diagnostics and rerun clippy until it succeeds. Do not skip warnings.
-
-6. Inspect `git status --short` and `git diff` to ensure only the Lance dependency update and required compatibility fixes are present.
-
-7. If the task only asks to prepare local changes, stop here and report the changed files and validation result.
-
-8. If the task asks to publish the update, create a branch using the printed `branch_name`, stage all relevant files, and commit using the printed `commit_message`. Do not amend or rewrite existing commits.
-
-9. Push to `origin`. Before creating the PR, check that the current token has push permission:
-
-   ```bash
-   gh api repos/lancedb/lancedb --jq .permissions.push
-   ```
-
-   If the remote branch already exists for the same generated branch name, delete the remote ref with `gh api -X DELETE repos/lancedb/lancedb/git/refs/heads/$BRANCH_NAME`, then push. Do not force-push.
-
-10. Create a PR targeting `main` with the printed `pr_title`. If there is no PR template, keep the body to two or three concise sentences: state the Lance dependency bump, note any required compatibility fixes, and link the triggering Lance tag or release.
-
-11. Read back the remote PR title after creation. If it is not a Conventional Commit title, fix it immediately.
-
-12. When running in GitHub Actions after creating the LanceDB PR, trigger the Sophon dependency update:
-
-    ```bash
-    gh workflow run codex-bump-lancedb-lance.yml \
-      --repo lancedb/sophon \
-      -f lance_ref="$LANCE_TAG" \
-      -f lancedb_ref="$BRANCH_NAME"
-    gh run list --repo lancedb/sophon --workflow codex-bump-lancedb-lance.yml --limit 1 --json databaseId,url,displayTitle
-    ```
-
-    Use the emitted metadata `tag` value as `LANCE_TAG`. Do this only after a new LanceDB PR has been created. If the update was skipped because no update is needed or an open PR already exists, do not trigger Sophon.
-
-## GitHub Actions
-
-When this skill is used from GitHub Actions, `TAG`, `GH_TOKEN`, and `GITHUB_TOKEN` may already be set. Resolve `latest` first when `TAG` is empty. Once an explicit tag or version is known, use:
-
-```bash
-python3 ci/update_lance_dependency.py "$TAG" --github-output "$GITHUB_OUTPUT"
-```
-
-Then use the emitted `branch_name`, `commit_message`, and `pr_title` values for branch, commit, and PR creation.

+          You are running inside the lancedb repository on a GitHub Actions runner. Update the Lance dependency to version ${VERSION} and prepare a pull request for maintainers to review.

-          Use \$lancedb-update-lance-dependency with target "${TARGET_TAG}".
+          Follow these steps exactly:
+          1. Use script "ci/set_lance_version.py" to update Lance Rust dependencies. The script already refreshes Cargo metadata, so allow it to finish even if it takes time.
+          2. Update the Java lance-core dependency version in "java/pom.xml": change the "<lance-core.version>...</lance-core.version>" property to "${VERSION}".
+          3. Run "cargo clippy --workspace --tests --all-features -- -D warnings". If diagnostics appear, fix them yourself and rerun clippy until it exits cleanly. Do not skip any warnings.
+          4. After clippy succeeds, run "cargo fmt --all" to format the workspace.
+          5. Ensure the repository is clean except for intentional changes. Inspect "git status --short" and "git diff" to confirm the dependency update and any required fixes.
+          6. Create and switch to a new branch named "${BRANCH_NAME}" (replace any duplicated hyphens if necessary).
+          7. Stage all relevant files with "git add -A". Commit using the message "${COMMIT_TYPE}: update lance dependency to v${VERSION}".
+          8. Push the branch to origin. If the remote branch already exists, delete it first with "gh api -X DELETE repos/lancedb/lancedb/git/refs/heads/${BRANCH_NAME}" then push with "git push origin ${BRANCH_NAME}". Do NOT use "git push --force" or "git push -f".
+          9. env "GH_TOKEN" is available, use "gh" tools for github related operations like creating pull request.
+          10. Create a pull request targeting "main" with title "${COMMIT_TYPE}: update lance dependency to v${VERSION}". First, write the PR body to /tmp/pr-body.md using a heredoc (cat <<'EOF' > /tmp/pr-body.md). The body should summarize the dependency bump, clippy/fmt verification, and link the triggering tag (${TAG}). Then run "gh pr create --body-file /tmp/pr-body.md".
+          11. After creating the PR, display the PR URL, "git status --short", and a concise summary of the commands run and their results.

          Constraints:
-          - Use env "GH_TOKEN" for GitHub operations.
-          - Do not merge the pull request.
-          - Do not force-push.
-          - Do not create a duplicate pull request if an open PR already exists for the target Lance version.
-          - If any command fails, diagnose and fix the root cause instead of aborting.
-          - After creating the PR, display the PR URL, "git status --short", and a concise summary of the commands run and their results.
+          - Use bash commands; avoid modifying GitHub workflow files other than through the scripted task above.
+          - Do not merge the PR.
+          - If any command fails, diagnose and fix the issue instead of aborting.

-## Cross-SDK parity
-
-LanceDB exposes the same core (`rust/lancedb`) through Python, TypeScript (`nodejs`),
-and Java bindings. Behavioral drift between SDKs is a recurring problem, so watch for
-parity gaps when reviewing — but only flag real ones:
-
-* If the change adds or modifies user-facing API or behavior in the shared core
-  (`rust/lancedb`), check whether each binding that should expose it (`python`,
-  `nodejs`) does. A core change with no corresponding binding update is worth a note.
-* If the change adds or modifies a public API in one SDK but not the other, open the
-  sibling SDK's corresponding module and state whether an equivalent exists. If not,
-  note it as a possible parity gap and suggest a follow-up issue.
-* For bug fixes, first read the sibling SDK's analogous code path to check whether the
-  same bug exists there. Only raise parity if it actually does. Do not ask to "port" a
-  fix for a bug that only ever existed in one binding.
-* Stay silent on internal-only refactors, tests, docs, and changes with no cross-SDK
-  surface.
-* Parity expectations apply to the Python and TypeScript (`nodejs`) SDKs. Java currently
-  implements only the remote table, not the local/embedded backend, so it is expected to
-  be partial — do not flag Java for missing local-only functionality.
-* Keep parity feedback to a short, clearly-labeled note (e.g. "Possible SDK parity
-  gap: …"). It is advisory, not a merge blocker.

-
-Controls how an LSM merge checks that its input targets a single shard.
-
-When a table has an LSM write spec, every row in a `mergeInsert` call must
-route to the same shard. When `true` (the default), every row is inspected
-to verify this. When `false`, only the first row is inspected and the
-shard it routes to is used for the whole input — a faster path for callers
-that have already pre-sharded their input. Has no effect on tables without

-# Function: instrumentLanceDbMetrics()
-
-```ts
-function instrumentLanceDbMetrics(meterProvider?): boolean
-```
-
-Register LanceDB metrics as OpenTelemetry observable instruments.
-
-Installs a process-global metrics recorder and creates one observable
-instrument per LanceDB metric (currently object store request counts, bytes,
-latency, errors, and throttles) on the given (or global) `MeterProvider`. The
-configured `MetricReader` then collects them on its own schedule.
-
-Counters and gauges map directly to observable counters/gauges. Because
-OpenTelemetry has no asynchronous histogram instrument, each histogram is
-exported Prometheus-style as cumulative `le` bucket counts (`<name>_bucket`,
-with an `le` attribute) plus `<name>_count` and `<name>_sum`.
-
-Requires `@opentelemetry/api` (a dependency) and, to actually export, an
-OpenTelemetry SDK such as `@opentelemetry/sdk-metrics`.
-
-## Parameters
-
-* **meterProvider?**: `MeterProvider`
-    The provider to register instruments on. Defaults to the
-    global provider from `@opentelemetry/api`.
-
-## Returns
-
-`boolean`
-
-`true` if the recorder is installed and instruments are registered.
-  `false` if a different `metrics` recorder is already installed in this
-  process (only one global recorder is permitted), in which case a warning is
-  emitted and no instruments are created. Calling this more than once is safe;
-  instruments are created only on the first successful call.

-    BENCH_STEPS      — round-robin cycles to time per chunk size (default 100)
-    BENCH_ROW_BYTES  — approximate bytes per row padded with a binary column
