nw-rigor

nw-rigor is a skill for Claude Code from nWave-ai/nWave. It costs 59 tokens per session (4,179 once invoked), scanned A, original, MIT.

A setting that chooses how much checking and detail a development workflow should use, from lean to exhaustive. The choice is saved globally or for one project.

In plain words
What is it for?
Use it to select a rigor profile and configure related review, TDD, model, and mutation-testing behavior.
Why use it?
It lets a team balance development speed against the amount of review, testing, and verification performed. It also keeps that choice consistent across workflow runs.

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

nw-rigor 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 4d 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.

NW-RIGOR: Quality Profile Selection

Wave: CROSS_WAVE | Agent: Main Instance (self) | Command: /nw-rigor [profile]

Overview

Interactive command to select a quality-vs-token-consumption profile. Persists choice to either ~/.nwave/global-config.json (global scope) or .nwave/des-config.json (project scope) under the rigor key. All wave commands read this config to adjust agent models, review policy, TDD phases, and mutation testing.

You (the main Claude instance) run this directly. No subagent delegation.

Note on TDD phase canons (dual-canon, ADR-025, 2026-05-07): the canonical TDD cycle is 3-phase v5 (RED, GREEN, COMMIT) as described in nw-tdd-methodology. The legacy 5-phase v4 (PREPARE, RED_ACCEPTANCE, RED_UNIT, GREEN, COMMIT) is preserved for backward-compat audit-log replay of pre-2026-05-07 commits. The .nwave/des-config.json tdd_phases field accepts BOTH canons: writers of new logs may emit v5; the validator + schema (step-tdd-cycle-schema.json) dispatch on schema_version ("5.0" → canonical, anything else → legacy). The profile table below shows both canons side-by-side: pick v5 for new features, keep v4 only when extending a feature whose audit log was started under the legacy canon.

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.

nw-rigor is a skill published in the GitHub repository nWave-ai/nWave (608 stars, last pushed 2d ago), licensed MIT. It adds 59 tokens to every session and 4,179 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
