fabric-skills-settings 0.5

Install Microsoft Fabric agent profiles (Claude Code and Codex) into a target repository.

Fabric Agent Pack

Vendor-native Codex and Claude Code profiles for Microsoft Fabric data engineering.

Fabric Agent Pack turns a normal git repository into a guided Microsoft Fabric project workspace. It installs agent instructions and lightweight scaffold files, while fabric-cli provides the setup, validation, notebook, pipeline, lakehouse, and workspace helpers from the package.

This repository is the source package and installer, not the day-to-day Fabric project workspace. Install a profile into your actual project repository, then run Codex or Claude Code from that target repository root.

Overview

Quick start

The CLI is published as fabric-skills-settings on PyPI. Installing it puts two console scripts on your PATH:

Command	Role
fabric-agents	Install / check / refresh agent profiles in a project repo
fabric-cli	Daily Fabric helpers run from a project repo (notebook, pipeline, lakehouse, workspace, lint, precommit)

Step 1 — Install the CLI

uv tool install fabric-skills-settings        # recommended
# or
pip install fabric-skills-settings

Step 2 — Install a profile into your project repo

# preview
fabric-agents install --profile claude --target /path/to/project-repo --dry-run

# apply (also runs fabric-cli setup: ms-fabric-cli + creds + workspaces.json)
fabric-agents install --profile claude --target /path/to/project-repo

# verify drift later
fabric-agents check --profile claude --target /path/to/project-repo

fabric-agents install copies the profile and scaffold files into the target, then runs fabric-cli setup from the target root to install ms-fabric-cli, prompt for FABRIC_TENANT_ID / CLIENT_ID / CLIENT_SECRET, verify auth, and populate workspaces.json. Pass --no-bootstrap to skip.

Step 3 — Daily work inside the project

Once a profile is installed, run the daily helpers via fabric-cli from the project root:

fabric-cli notebook build  <name>
fabric-cli notebook deploy <name> <workspace_id>
fabric-cli pipeline manage list
fabric-cli lakehouse list-tables
fabric-cli workspace switch <displayName>
fabric-cli lint
fabric-cli precommit

Each subcommand passes its trailing argv through to package-bundled helpers while preserving the target repo as the working directory. Use fabric-cli <group> --help to see what each helper accepts.

fabric-agents flags

Flag	Effect
--profile {codex,claude,all} / -p	Pick the agent profile (required)
--target <path> / -t	Target git repository (required)
--dry-run	Preview changes without writing (install/refresh only)
--force	Overwrite non-managed existing files
--backup	Back up replaced files alongside the originals
--no-bootstrap	Copy files only; skip the post-install Fabric auth + workspaces.json bootstrap (install only)
--verbose / -v	Debug-level logging
--quiet / -q	Suppress info logging
--help / -h	Show usage

Service-principal credentials

Minimum Fabric workspace role: Contributor. The bootstrap prompts for these and stores them safely:

Prompt	Stored where
FABRIC_TENANT_ID	<target>/.env
FABRIC_CLIENT_ID	<target>/.env
FABRIC_CLIENT_SECRET	OS environment only — never .env

On Windows the secret is written to the user registry via SetEnvironmentVariable("User"). On Linux/macOS it is appended to your shell profile (~/.zprofile, ~/.bash_profile, or ~/.profile).

Create the service principal once, before running setup:

Azure Portal → App registrations → New registration
  Name: fabric-agent-<project>
  Supported account types: this tenant only

Fabric workspace → Manage access → Add → service principal
  Role: Contributor

Re-running the same install command is idempotent — credentials already set are skipped, and managed files only change when their source content changes. If you need to bootstrap again later (e.g. after rotating the secret), run fabric-cli setup from inside the target.

Example result

The screenshots below show an end-to-end bronze ingestion of EU day-ahead electricity prices into a Fabric Lakehouse.

1 — Authoring the bronze notebook

The developer agent authors bronze_electricity_day_ahead_prices.py while the upstream download_sources job runs in Fabric.

2 — Deploying and triggering

Codex reads the workspace ID from .env, deploys the notebook through the Fabric REST API, and triggers the run.

3 — Full run history

The Fabric Monitor shows download_sources → bronze_electricity_day_ahead_prices → dq_bronze_electricity_day_ahead_prices succeeding after schema-contract iterations.

4 — Ingested Delta table

The resulting Delta table contains 1,000 rows and 27 columns, including lineage envelope fields such as _ingest_timestamp, _source_system, and _batch_id.

5 — Restricted workspace for AI agentic development

The agent runs in a dedicated workspace. Permissions are set at the workspace level to ensure there is no access to production data or pipelines.

6 — Development Lifecycle

The code is integrated with Git, and the agent develops everything in a dedicated feature branch. Human developers can review the pull request later and merge the work from the feature branch into dev.

Note: The VIBECODING workspace was set up by selecting individual Fabric items. This narrowed down the codebase to only the scripts that stakeholders actually care about.

Live reference implementation

fabric-open-data-lu is a public target repository with Claude- and Codex-generated scripts for EU open-data ingestion into Microsoft Fabric. It demonstrates the download_ → bronze_ → dq_bronze_ notebook pattern used by this package.

Why use it?

• Ship faster — agents handle notebook authoring, deployment, schema validation, and pipeline wiring. Engineers own approvals and production handoffs.
• OWASP-compliant by default — Data Security Top 10 and Supply Chain (A03:2025) baked in: no credential leakage, parameterized queries, pinned dependencies, CVE checks, PII masking.
• Harness engineering — agents run inside a structured harness of guardrails, role definitions, skill boundaries, and memory. Consistent, auditable behavior without custom prompt engineering per project.
• Separation of duties — implementation, testing, and security review are distinct agents. Nothing reaches production without a human sign-off.
• Quality gates at every layer — mandatory Great Expectations checks at bronze, silver, and gold. Failed DQ stops the pipeline; agents do not auto-retry.
• Token savings — RTK optimizer cuts shell-output tokens 60–90%, keeping long sessions economical.
