nobrainer-ultra is a skill for Claude Code from nobrainer-tech/nobrainer-tech-skills. It costs 49 tokens per session (2,385 once invoked), scanned A, original, MIT.

A workflow skill for taking a non-trivial project request from a brief through planning, specialist methods, guarded execution and a final evidence review. It also supports setting up or repairing that workflow.

In plain words
What is it for?
Use it to plan and execute substantial development tasks, route work to suitable methods, verify the result and audit the evidence.
Why use it?
It coordinates the stages of complex agent work so important decisions, checks and corrections are not lost between steps or sessions.

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

nobrainer-ultra 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 7d 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.

NoBrainer Ultra

Deliver the smallest verified outcome; surface scope, proof and blockers.

Small tasks need no companions. For non-trivial work read references/routing.md. Keep the host-selected model and default effort; read references/model-routing.md only when choosing models, effort or budgets. Setup, upgrade, installation or repair require references/setup.md. Read references/correction-hooks.md after owner decision changes, correction or review failure; read references/long-run-state.md only when its gate passes.

Choose the smallest workflow

Quick path for small changes

For a clear low-risk answer, rewrite, calculation or one coherent, reversible edit, deliver and check the result directly. Chat-only work needs no repository or tools. For file edits inspect instructions, actual files and the nearest deterministic check; use checkout, dirty-state and git diff --check only in a Git repository. Skip requirements, ledger, team/dispatcher/sessions and independent review. Escalate to the full Ultra lifecycle for ambiguity, architecture, public behavior, workflow/routing changes or consequential side effects; quick path never bypasses an owner gate. A wording-only correction does not itself change a public contract.

Default to one agent; add workers only when latency, isolation or judgment earns their cost.

Lifecycle: DRIFT_CHECK -> BUDDY -> SCOPE -> AUTOPILOT -> VERIFY -> RECEIVE_AUDIT -> LEARN; these are internal controls.

For resumable or delegated work use SESSION_HEALTH_GATE and RUNTIME_RELEASE from the long-run reference. Optional telemetry is not an execution prerequisite. Finish when acceptance is met; wait or audit when workers are in flight. Use OWNER_DECISION_REQUIRED only when unfinished work needs an owner decision.

DRIFT_CHECK: establish current truth

Inspect the actual inputs, instructions and required capabilities; for project work include dirty state, callers, tests and existing plan/spec. Preserve unrelated work. Prior summaries, wiki and worker reports are context, not proof; query wiki only for a decision or lesson that can change this task. Research current, external, niche, uncertain, high-stakes or attributed facts. For large documents or data and repositories, inspect structure first, then read selected contracts in full and relevant ranges; respect context budget and name unread required surface.

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.
