ultra-vnext-core

ultra-vnext-core is a skill for Codex from keithhegit/ultra-orchestration. It costs 81 tokens per session (951 once invoked), scanned A, original, Apache-2.0.

A compatibility entry point for the strict Ultra Orchestrator workflow. It selects a run mode and coordinates planning, execution, review, and related records for a development task.

In plain words
What is it for?
Use it for bug fixes, multi-file development work, OpenSpec tasks, orchestration tests, or other work that needs structured artifacts and review gates.
Why use it?
It lets existing users invoke the newer orchestration process through the older skill name while retaining its stricter planning and validation rules.

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

ultra-vnext-core 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 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/new_run.py, scripts/validate_contracts.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ultra VNext Core

Use this skill as a compatibility alias for the mainline $ultra-orchestrator protocol. The user should not need to list every subskill.

Prefer the same behavior as the new main entry point:

$ultra-orchestrator <task description>

$ultra-vnext-core <task description> remains valid for existing users and pilot runs.

Run Mode Decision

Classify the run before planning or execution:

  • LIGHT review-only, QA-only, explanation-only, or user-explicit lightweight work
  • STANDARD user-explicit fast orchestration with bounded risk and no full control plane
  • STRICT development work where OpenSpec is unavailable but ledger and JSON contracts are still required
  • STRICT_OPENSPEC default for development work, bug fixes, multi-file implementation, pilots, full orchestration tests, OpenSpec work, slice DAG work, and control-plane validation

Development tasks must prefer STRICT_OPENSPEC. If that mode is impossible, explain why and downgrade explicitly. Markdown-only artifacts are not enough for STRICT or STRICT_OPENSPEC.

Router Duties

When invoked:

  1. classify the task and choose run_mode
  2. create or require OpenSpec change scaffolding when STRICT_OPENSPEC applies
  3. initialize the run ledger for STRICT and STRICT_OPENSPEC
  4. route through the minimal required sibling skills
  5. validate machine-checkable artifacts before delivery
  6. produce delivery artifacts or a clear blocker

Do not ask the user to manually name every subskill.

Strict Control Plane

For STRICT and STRICT_OPENSPEC, the run must use:

  • scripts/new_run.py to initialize a run directory
  • ledger.json as the execution state record
  • JSON TaskManifest
  • JSON WorkPackage
  • JSON or structured AgentResult
  • scripts/validate_contracts.py for core artifact validation
  • explicit review and QA gates
  • final control_surface_used

If a required script or artifact cannot be used, stop with a blocker instead of silently downgrading to markdown-only orchestration.

What ships with it

What this file has done since we first saw it

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.
