nw-spike SKILL.md skillA
nw-spike from nwave-ai/nwave is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nwave-ai/nwave/nw-spike@git:20260416.53525a8Pins git:20260416.53525a8 in mdr.lock. Pin the fingerprint instead.

Runs a timeboxed PROBE to validate one core assumption, then optionally PROMOTES the probe into a walking skeleton — the first e2e thin slice of the feature, committed and demo-able. Use after DISCUSS when the feature involves a new mechanism, performance requirement, or external integration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NW-SPIKE: Probe → Walking Skeleton
**Wave**: SPIKE (between DISCUSS and DESIGN) | **Agent**: Attila (nw-software-crafter) | **Command**: `/nw-spike`
## Overview
Execute a two-phase wave that turns a risky assumption into visible, iterable value as fast as possible:
1. **PROBE** — quick throwaway validation of one core assumption (30-60 min, code in `/tmp/`)
2. **PROMOTION GATE** (interactive) — ask the user whether to promote the probe
3. **WALKING SKELETON** — refactor the probe into an end-to-end thin slice committed to the repository (1-3 h, code in `src/` + 1 acceptance test)
The PROBE answers "does the mechanism work?". The WALKING SKELETON answers "can a user see it working end-to-end?". You never throw away working validated code — you promote it and iterate.
## When to use
The spike is needed when the feature introduces:
- A new mechanism never tried in this codebase
- A performance requirement that cannot be validated by reasoning alone
- An external integration with unknown behaviour
If none of the above apply, skip SPIKE and go to DESIGN.
## Prior Wave Consultation
1. **DISCUSS artifacts**: Read `docs/feature/{feature-id}/discuss/` (required)

How to install
mdr add nwave-ai/nwave/nw-spike@sha256:ed8675fa8a8d492fThe line at the top of this page pins the label git:20260416.53525a8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
