vcfa-authoring

vcfa-authoring is a skill for Claude Code from mgovedarov/mcp-vcf-orchestrator. It costs 113 tokens per session (1,017 once invoked), scanned A, original, Apache-2.0.

Guidance for creating and promoting VMware VCF Automation Orchestrator content through its MCP server. This content includes workflows, actions, configuration items, resources, and packages.

In plain words
What is it for?
Use it to discover available vRO capabilities, design or update reusable automation content, validate its contract, and promote or import it safely.
Why use it?
It requires checking the live environment before writing and confirming changes before they affect it. That helps avoid invented identifiers, incorrect input schemas, and unsafe live edits.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vcfa-authoring scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

VCFA Authoring

Drive the VCF Automation Orchestrator MCP server when authoring or promoting vRO artifacts. Stay discovery-first and conservative with the live environment. This skill orchestrates the server's own prompts, resources, and tools — it does not replace them.

Core principles

  • Discover before you write. Start with the list-* and get-* tools and verify every ID, category, schema, and contract from the live environment, docs, or configured tools. Never invent vRO IDs, parameter schemas, action contracts, package names, or category IDs.
  • Mutating tools require a confirm: true argument. That schema flag is not a substitute for real user confirmation — confirm the exact target, expected impact, and rollback or backup plan with the user before any live write.
  • Keep local artifact work inside the configured artifact directories. Pass plain file names, never paths, absolute paths, traversal, or symlinks.

Prefer the server prompts

Reach for the server-provided prompts first — they encode the full playbooks:

  • vcfa-discover-capabilities — explore installed plugins, categories, reusable actions, workflows, and gaps before designing anything.
  • vcfa-collect-context-snapshot — persist reusable environment context in unfamiliar or large environments.
  • vcfa-discovery-first-implementation-plan — produce a phased plan that begins with verified read-only discovery.
  • vcfa-author-workflow — plan, scaffold, preflight, and safely import a workflow.
  • vcfa-build-workflow-from-action — wrap an existing action's verified contract in a workflow.
  • vcfa-refactor-workflow — inspect, export, diff, and plan a safe refactor.
  • vcfa-review-artifact-import — review a local artifact before import.

Artifact lifecycle

Follow this sequence unless the user explicitly asks for a narrower read-only review:

  1. Discover the live target and dependencies with list-* / get-* tools.
  2. Export or snapshot existing live state when replacing content (export-workflow-file, export-action-file, export-configuration-file, export-resource-element, export-package).
  3. Author or modify the local artifact (scaffold-workflow-file, create-workflow, create-action, create-configuration).
  4. Validate with the matching preflight tool (preflight-workflow-file, preflight-action-file, preflight-configuration-file, preflight-package).
  5. Diff when replacing a workflow or action (diff-workflow-file, diff-action-file).
  6. Run prepare-artifact-promotion to bundle preflight, optional backup export, and change summaries before a live replacement.
  7. Confirm the exact target and impact with the user.
  8. Import or publish (import-workflow-file, import-action-file, import-configuration-file, import-resource-element, import-package).
  9. Verify with read-only inspection or a confirmed execution.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
