-## Design Reasoning Defaults
-
-When proposing a design, an approach, or any non-trivial change, apply these
-defaults and run the self-check before presenting it. They encode the
-corrections users most often have to make; reaching these conclusions
-autonomously — without being asked the leading question — is the bar.
-
-- **MUST**: Optimize for the best outcome, not for an unstated constraint. Do not
-  silently adopt "smallest change", "least effort", "cheapest", or "least user
-  intervention" as the goal unless the user said so. Default to the most correct,
-  durable solution, and present cost / effort / scope as information for the user
-  to weigh — not as a ceiling you impose on their behalf.
-- **MUST**: Separate one-time cost from recurring cost before discarding an
-  option. A fixed cost paid once (a setup-time computation, an extra LLM call
-  during setup, a contract change) to make every later run cheaper or more
-  correct is usually worth it. Do not reject it with recurring-cost reasoning;
-  quantify both sides. (Example smell: "don't add an LLM call to a cost-cutting
-  feature" — wrong when the call is one-time and the savings recur.)
-- **MUST**: Treat a user's example as a representative of a class, not as the
-  spec. Design for the general population the example stands for, then stress-test
-  against deliberately different instances — another warehouse, dialect, stack
-  layout, or input shape — before committing. If a design only works because of an
-  incidental property of the example (e.g. "the noise happened to be in a separate
-  schema *on this demo*"), it is curve-fitting; generalize it or state the
-  assumption explicitly.
-- **MUST**: Prefer deriving from the system's own state over enumerating cases.
-  Favor an allowlist computed from declared/observed state (config, scanned
-  catalog, query log, the user's own inputs) over a denylist of known-bad
-  specifics (particular tables, schemas, tools, or vendors). A hardcoded or
-  hand-maintained list of external specifics is a smell: it rots and fails on the
-  next stack. The only acceptable static patterns are genuinely universal
-  invariants (e.g. DB-engine system catalogs) and ktx's own self-emitted
-  signatures.
-- **SHOULD**: Before inventing an abstraction or hand-rolling structural logic,
-  search for what already exists and reuse it — the codebase's canonical
-  representation (a structured ref/key type) instead of a parallel string scheme,
-  and a mandated/available tool (e.g. `sqlglot` for SQL structure; see
-  [SQL and Structured Parsing](#sql-and-structured-parsing)) instead of
-  hand-parsing. Normalize ambiguous input to the canonical form at the boundary;
-  do not carry the ambiguity downstream. This is the single-source-of-truth / DRY
-  item from the Priority Hierarchy applied at design time.
-
-Before presenting a design, answer these explicitly:
-
-1. Am I optimizing for a goal the user actually stated, or one I assumed?
-2. Does this generalize beyond the example in front of me? Name a real case where
-   it would break.
-3. Am I enumerating known-bad cases when I could derive scope from the system's
-   own declared/observed state?
-4. Is there an existing canonical representation or mandated tool I should reuse
-   instead of building or parsing my own?
-5. Am I discarding the better option on a weak or misapplied constraint
-   (one-time vs recurring cost, "more surface area", "more work now")?
-
-A user question that nudges toward an alternative ("would X help?", "should I
-always do Y?", "will you hardcode Z?") is a signal that a better option exists.
-Investigate the implied direction and reason it through *before* defending the
-original proposal — and prefer to have asked yourself the question first.

-- **MUST**: When adding a new container that renders user-visible monospace

-- **Which LLM backends are supported?**
-  Anthropic API, Google Vertex AI, AI Gateway, the local Claude Code session
-  through the Claude Agent SDK, and your local Codex authentication through the

-  **ktx** *ingests* those layers and combines them with raw-table
-  introspection and wiki content. Agents get one searchable surface instead
-  of three disconnected ones - and **ktx** flags contradictions across
-  sources.
-- **Does ktx need a running server?**
-  There is no hosted service. The local MCP daemon runs on demand via
-  `ktx mcp start` when an agent client needs it.
-- **Is my warehouse safe?**
-  Yes. Connections are read-only - **ktx** never writes to your database.
+```bash
+ktx setup --agents
+```

+During setup, choose **Ask data questions with ktx MCP** for agent clients.
+Choose **Ask data questions + manage ktx with CLI commands** when an operator
+agent also needs pinned `ktx` admin commands.
+
+After setup, **ktx** prints **Required before using agents** with the exact
+commands to run. If the output includes `ktx mcp start --project-dir ...`, run
+it before opening your agent. Claude Desktop uses its own launcher and prints
+separate skill upload steps under `.ktx/agents/claude/`.

-## Telemetry
+## Docs
 
-**ktx** collects privacy-conscious usage telemetry to understand installs and
-improve setup, command reliability, and data-agent workflows. Catalog telemetry
-events do not record file paths, hostnames, SQL, schema names, table names,
-column names, error messages, raw environment values, or argv. Error reports use
-PostHog Error Tracking and can include stack frames and raw error messages,
-which may contain local file paths or the local username in those paths.
-**ktx** redacts secrets, credentials, database URLs, auth headers, argv, raw
-environment values, SQL text, row data, and user-typed prompt or MCP argument
-text from the explicit `$exception` payload. See
-[Telemetry](https://docs.kaelio.com/ktx/docs/community/telemetry) for the event
-catalog and opt-out options.

+# Goal
+
+Set up **ktx** from scratch end-to-end as a fully autonomous, agent-driven replacement for the interactive `ktx setup` wizard. Detect the environment, install missing prerequisites, ask the user only for information you genuinely need (which connections to add, credentials), write a valid configuration, verify it works, and run a fast ingest. Keep the user updated throughout.
+
+# Operating principles
+
+- **Be autonomous.** Detect, decide, and act. Only ask the user when you need information that only they can provide: project location, which databases/sources to connect, credentials, and similar choices.
+- **Stream short status updates.** Before each major phase ("Checking prerequisites…", "Installing uv…", "Configuring warehouse connection…", "Running fast ingest…") print a one-line update. Not chatty - just enough that the user can see what's happening.
+- **Verify against docs, never guess.** CLI flags, config keys, and command names must come from the docs or from `ktx <command> --help`. If something looks wrong or missing, say so explicitly.
+- **Print every command you run and its exit code.** Terse, not silent.
+- **Fail loudly with cause + fix.** When a command fails: capture the exact error, identify the cause, change something, retry. Never retry an unchanged command. Exceptions for *known soft-failures* are listed in Phase 4 - handle those without retrying.
+- **No LLM-based ingestion in this flow.** Only `--fast` ingest. The user can run `--deep` later.
+- **Platform-agnostic.** Detect the host OS first and pick the right install commands / path syntax. Anything path- or shell-specific must branch on OS.
+
+# Authoritative docs
+
+**ktx** docs are served at `https://docs.kaelio.com/ktx/`. **Start by fetching `https://docs.kaelio.com/ktx/llms.txt`** to discover the docs map. Scan it for a "troubleshooting" entry - if one exists, read it **before** running install/setup so you can apply known fixes preemptively rather than after failing. If no troubleshooting page is listed (current state of the docs), proceed. Then fetch any other `.md` pages you need (setup, ingest, status, connection types). **Never invent CLI flags or config keys** - verify against the docs or `ktx --help` / `ktx <subcommand> --help`.
+
+> **Note on the `ktx status` JSON example in the docs.** The docs page for `ktx status` shows an example shaped like `{"title": "...", "checks": [...]}`. That example is outdated. The real CLI output uses a top-level `verdict` field plus a `connections[]` array - see Phase 5 for the canonical success criteria. Trust the shape in this prompt over the docs example.
+
+# Workflow
+
+## Phase 1 - Detect environment
+
+Determine the host OS (e.g. via `uname -s`, `process.platform`, or `$env:OS`). Use the right install commands per OS for the rest of this flow.
+
+| Tool | macOS / Linux | Windows (PowerShell) |
+|------|---------------|----------------------|
+| `uv` | `curl -LsSf https://astral.sh/uv/install.sh \| sh` then re-source shell env | `irm https://astral.sh/uv/install.ps1 \| iex` |
+| Node.js | use system / fnm / nvm - **do not** auto-install | use system / nvm-windows - **do not** auto-install |
+| **ktx** CLI | `npm install -g …` (see Phase 2) | `npm install -g …` (see Phase 2) |
+
+If Node.js is missing, **stop and ask the user** to install it (https://nodejs.org/). Do not attempt to auto-install Node.
+
+## Phase 2 - Verify and install prerequisites
+
+Check each tool in order; install only if missing.
+
+1. **Node.js** - run `node --version`. Require >= 22. If missing or older, stop and instruct the user.
+2. **`uv`** - run `uv --version`. If missing, run the OS-appropriate install command, then re-source the shell environment (`export PATH="$HOME/.local/bin:$PATH"` on Linux/macOS) so `uv` is on `PATH`.
+3. **ktx CLI** -
+   - Install ktx with `npm install -g @kaelio/ktx`
+   - Verify with `ktx --version`.
+
+Print one status line per tool ("✓ uv 0.11.15 found", "Installing uv…", "✓ ktx 0.x.y installed").
+
+## Phase 3 - Gather user choices
+
+Ask the user (grouped if your harness supports it; otherwise sequentially):
+
+1. **Project directory.** Default: current working directory. Confirm before continuing.
+2. **LLM provider.** Default: `claude-code` with model `sonnet` (the user is already inside Claude Code; no extra API key needed). Offer `anthropic` (paste API key, stored as `env:` or `file:` ref) and `vertex` (GCP project + location) as alternatives. Skip if defaults are accepted.
+3. **Embeddings backend.** Default: `sentence-transformers` (local, no API key, managed Python runtime). Offer `openai` only if the user has a key.
+4. **Database connections.** Ask how many to add, then loop. For each, collect:
+   - Connection name (e.g. `warehouse`, `analytics`).
+   - Driver: one of `sqlite`, `postgres`, `mysql`, `sqlserver`, `bigquery`, `snowflake`.
+   - Connection URL/DSN (or service-account file for BigQuery). Accept `env:VAR_NAME` or `file:/abs/path` to avoid pasting raw secrets.
+     - **Heads-up for the user**: even if they paste a literal URL, **ktx** will silently relocate it into `<project>/.ktx/secrets/<connection>-url` and rewrite `ktx.yaml` to `url: file:…` - this is correct, secure behavior and not a bug.
+   - Schemas / datasets to include (postgres / sqlserver / snowflake / bigquery only).
+   - Optional `enabled_tables` allowlist if the user wants to scope ingest to specific tables.
+5. **Context sources** (dbt, Metabase, Looker, LookML, MetricFlow, Notion). Default: none. Ask only if the user mentions them.
+
+## Phase 4 - Configure the project
+
+Drive the existing wizard non-interactively (verify exact flag names with `ktx setup --help` and the docs - the automation flags are hidden from help but accepted):
+
+```
+ktx setup \
+  --project-dir <path> \
+  --no-input --yes \
+  --llm-backend <claude-code|anthropic|vertex> --llm-model <model> \
+  [--anthropic-api-key-env ANTHROPIC_API_KEY | --anthropic-api-key-file <path>] \
+  [--vertex-project <p> --vertex-location <loc>] \
+  --embedding-backend <sentence-transformers|openai> \
+  [--embedding-api-key-env OPENAI_API_KEY] \
+  --skip-sources \
+  --database <driver> --database-connection-id <name> --database-url <url|env:VAR|file:/path> \
+    [--database-schema <schema> …]
+```
+
+Notes on the flags above:
+- **Project creation is automatic with `--no-input --yes`.** When
+  `ktx.yaml` exists, setup resumes it. When it doesn't exist, setup creates it
+  at `--project-dir`.
+- **`--database-connection-id` is dual-purpose.** With `--database` or
+  `--database-url`, it names the new connection. Without those flags, it
+  selects an existing connection id.
+- **Configure one new database connection per setup command.** If the user
+  wants multiple new connections, run setup again for each connection.
+- **You don't need `--skip-agents` in this flow.** The agent integration step
+  is opt-in: setup leaves it alone unless you pass `--agents --target
+  <target>`.
+- **`--skip-sources`** is correct and is the documented way to leave context sources unconfigured.
+
+### Known soft-failure: `ktx setup` exits 1 after a successful fast build
+
+When you select a configuration that only does fast ingest, `ktx setup`'s final readiness verification fails with:
+
+```
+ktx context build did not pass agent-readiness verification.
+  <connection>: deep database context has not completed.
+```
+
+This is **expected** and **does not mean setup failed**. Treat the exit code as a soft-failure **only if all of the following hold**:
+
+- The build log shows the fast ingest reached `[100%] Scan completed` for every configured connection.
+- `ktx connection test <name>` (run next) exits 0 for every connection.
+- `ktx status --json --no-input` reports `verdict: "ready"`.
+
+If those three conditions hold, proceed to Phase 5 without retrying setup, and **do not** switch to `--deep` to "fix" the readiness gate - deep ingest is explicitly out of scope. Mention this in the final report under "Docs / CLI gaps" so the user is aware.
+
+If any of those three conditions do not hold, this is a real failure - capture the error, fetch the relevant docs page, fix the cause, retry.
+
+After `ktx setup` writes `ktx.yaml`, edit it directly for anything flags don't cover:
+- Per-connection `enabled_tables` allowlist (snake_case, under `connections.<name>.enabled_tables`).
+- Any advanced settings the user requested.
+
+Use a YAML-aware editor (e.g. `uv run python -c "import yaml; …"`) - do not hand-edit blindly.
+
+## Phase 5 - Verify
+
+`ktx setup` already runs a fast ingest of every database connection it configures, so you do not need to re-ingest by default. For each configured connection:
+
+```
+ktx connection test <connection-name>        # must exit 0
+```
+
+Only re-run ingest if setup's build log did **not** reach 100% for that connection:
+
+```
+ktx ingest <connection-name> --fast --no-input
+```
+
+**Mutex warning on `ktx ingest`**: passing both `--yes` and `--no-input` fails with `Choose only one runtime install mode: --yes or --no-input`. Setup already installed the managed Python runtime, so pass **only `--no-input`** to `ktx ingest`. (`--yes` is only needed when an ingest invocation has to install the runtime itself, which is not the case here.)
+
+Then run the global health check:
+
+```
+ktx status --json --no-input
+```
+
+Success requires (canonical shape - supersedes the example in the docs):
+- `verdict: "ready"` at the top of the JSON.
+- Every `connections[].status === "ok"`.
+- `ktx connection test <name>` exited 0 for every connection.
+
+Do **not** run `--deep` ingest in this flow - that requires LLM time and is out of scope.
+
+### Optional: directly probe the ktx daemon
+
+If the user asks for stronger verification that `sentence-transformers` is actually serving (not just that setup said "ok"), do all of:
+
+1. `ktx admin runtime status --json` → expect `"kind": "ready"` and `"features": [..., "local-embeddings"]`.
+2. `pgrep -fa ktx-daemon` → expect a process running `ktx-daemon serve-http`.
+3. `curl -sS http://127.0.0.1:<port>/health` → expect HTTP 200 with `{"status":"healthy",…}`.
+4. `curl -sS -X POST http://127.0.0.1:<port>/embeddings/compute -H 'content-type: application/json' -d '{"text":"hello"}'` → expect `{"embedding": [...384 floats...]}`.
+
+Discover the port from setup's log line `Started ktx daemon: http://127.0.0.1:<port>` or from the daemon's OpenAPI at `GET /openapi.json`. Note: the routes are `/health` and `/embeddings/compute` - not `/healthz` or `/embeddings`.
+
+## Phase 6 - Final report
+
+Print a structured report:
+
+```
+ktx SETUP COMPLETE
+
+Project:     <path>
+LLM:         <backend> / <model>
+Embeddings:  <backend> / <model>

+
+Sources:     <list or "none">
+Verdict:     ready
+```
+
+Then **Next steps** (copy-pasteable):
+1. Enrich with AI descriptions and embeddings: `ktx ingest <connection> --deep` (several minutes per connection).
+2. Add more connections later by rerunning this setup or via `ktx setup --database … --database-connection-id …`.
+3. Configure context sources (dbt, Metabase, Looker, LookML, MetricFlow, Notion) - see `ktx setup --help` for `--source …` flags.
+4. Install agent integration: `ktx setup --agents --target <claude-code|claude-desktop|codex|cursor|opencode|universal>` (with optional `--global` for `claude-code`/`codex`).
+5. Connect the agent / MCP: see docs at `https://docs.kaelio.com/ktx/`.
+
+Under **Docs / CLI gaps to flag** include any of these that applied during your run:
+- `ktx setup` exits non-zero after a successful fast build (deep-readiness gate); status reports ready.
+- `ktx ingest` rejects `--yes` and `--no-input` together; docs don't note the conflict.
+- `ktx status --json` real shape (`verdict`, `connections[]`) doesn't match the example in the docs page.
+- The pasted DB URL was moved to `.ktx/secrets/<name>-url` automatically.
+
+End with a single line: `RESULT: PASS` or `RESULT: FAIL - <one-line reason>`.
+
+# Operating rules (recap)
+
+- Print every command you run and its exit code. Status updates may be terse, but never silent.
+- On failure: capture the error, fetch the relevant docs page, fix the cause, retry. Never retry an unchanged command.
+- Known soft-failures (listed in Phase 4 and Phase 5) are not real failures - handle them as documented; do not retry or escalate.
+- If you find a docs/CLI gap ("docs say X but CLI does Y"), call it out in the final report.
+- Never commit credentials - **ktx** accepts `env:` and `file:` references; prefer those. **ktx** will also auto-relocate literal URLs into `.ktx/secrets/`, but that does not protect anyone who pasted the URL into chat history.

-
-Print a shell completion script for **ktx**. Once installed, pressing <kbd>Tab</kbd>
-completes commands, subcommands, and flags, and - inside a **ktx** project - the
-names of things that already exist: semantic-layer source names for
-`ktx sl read` and `ktx sl validate`, wiki page keys for `ktx wiki read`, and
-configured connection ids for `ktx connection test`, `ktx ingest`, and
-`ktx sql`. This saves you from remembering exact source, page, or connection

-```
-
-`<shell>` must be `zsh` or `bash`. The command writes the script to stdout; it
-does not modify any files. Enable completion by evaluating the script in your

-
-## Installation
-
-Add the matching line to your shell startup file, then restart your shell (or
-`source` the file). `ktx` must be on your `PATH`.
-
-```bash
-# zsh — add to ~/.zshrc

-## What gets completed
-
-| Position | Completions |

-| `ktx wiki read <Tab>` | Existing wiki page keys |
-| `ktx connection test <Tab>` | Configured connection ids |

-| `ktx sl --output <Tab>` | An option's allowed values (here `pretty`, `plain`, `json`) |
-| `ktx sl --connection-id <Tab>` | Configured connection ids |
-
-Source names, wiki page keys, and connection ids are read from the **ktx**
-project resolved from your current directory (or `--project-dir` /
-`KTX_PROJECT_DIR`). Outside a **ktx** project, completion still suggests
-commands and flags but no project entities. Bare `ktx sl <Tab>` and
-`ktx wiki <Tab>` complete subcommands instead of entity names because their
-positional arguments are free-text search queries.

-## Dispatch and contract leaks across per-variant layers
-
-Layers with multiple per-variant implementations (warehouse drivers,
-dialects, LLM providers, ingest adapters, historic-SQL probes) drift
-toward parallel switches and informal contracts. The patterns below
-look locally reasonable per file but multiply with the number of
-variants times the number of consumers — every fix has to be applied
-N times, and silent drift between variants is invisible until a user
-hits it.
-
-- **MUST NOT**: Maintain two or more files that switch on the same
-  enum or string union to dispatch to per-variant behavior. Promote
-  the dispatch to a single registry table keyed by the union, exposed
-  through one resolution function. If you find yourself writing the
-  third such switch, the second one was already a bug.
-- **MUST**: When every variant of an abstraction implements the same
-  method, the method belongs on the shared interface. An informal
-  contract that every implementation happens to satisfy is a leak
-  waiting to happen — callers will reach for the concrete class
-  instead of the contract, and the next variant added will silently
-  forget to implement it.
-- **MUST**: When a layer has both a thin shared interface and rich
-  per-variant concrete classes, they must agree. Either widen the
-  interface so callers never need the concrete class, or make the
-  concrete class private (test-only `/** @internal */` JSDoc plus a
-  boundary check in `scripts/check-boundaries.mjs`). A class that is
-  public AND has methods the interface does not expose is the exact
-  configuration that produces leaks.
-
-The warehouse driver / dialect layer in
-`packages/cli/src/connectors/<driver>/` plus
-`packages/cli/src/context/connections/{dialects,drivers}.ts` is the
-canonical worked example: per-driver dialect classes carry
-`/** @internal */`, `scripts/check-boundaries.mjs` enforces the import
-boundary, and dispatch lives in the two registry files. Apply the
-same shape to any other per-variant layer that grows beyond two
-implementations.

-## Context Layer and Context Engine
-
-Use **context layer** as the primary category term for what **ktx** provides to
-data agents.
-
-Use **context engine** as the secondary mechanism term for how **ktx** builds,
-maintains, validates, and serves that layer.
-
-| Concept | Use | Do not use |
-|---|---|---|
-| The whole **ktx** product category | **context layer** / **context layer for data agents** | knowledge layer, agent memory |
-| The active system that builds and maintains context | **context engine** | context layer when describing ingest/reconciliation internals |
-| The durable reviewed surface agents use | **context layer** | context engine |
-| The compiler pillar for executable metrics and joins | **semantic layer** | context layer when specifically discussing SQL compilation |
-| Prose/business knowledge files | **wiki** / **wiki pages** | wiki context |
-
-### Usage rules
-
-- Use **context layer** in taglines, page titles, meta descriptions, docs
-  introductions, comparison pages, and first-paragraph definitions.
-- Use **context engine** when describing active behavior: ingesting evidence,
-  reconciling changes, validating references, maintaining files, search, CLI,
-  and MCP serving.
-- Keep **semantic layer** for the narrower YAML/compiler surface: semantic
-  sources, measures, joins, dimensions, filters, SQL compilation, and semantic
-  queries.
-- Do not use **context engine** as the primary replacement for the whole
-  product. It sounds like runtime infrastructure; **context layer** better
-  describes the durable YAML and Markdown surface users review in git.
-- Do not use **context layer** when the sentence is specifically about the
-  compiler. Example: write "the semantic layer compiles semantic queries to
-  SQL," not "the context layer compiles semantic queries to SQL."
-- Default lowercase in prose: `context layer`, `context engine`, `semantic
-  layer`. Title case only in page titles, headings, nav labels, and UI labels.
