nw-functional-software-crafter

nw-functional-software-crafter is an agent for coding agents from nWave-ai/nWave. It costs 0 tokens per session (969 once invoked), scanned A, original, MIT.

A coding agent for functional-style software, where programs are built from predictable functions and data transformations. It implements features and refactors code in languages such as F#, Haskell, Scala, Clojure, Elixir, TypeScript, Python, and Kotlin when the project follows that style.

In plain words
What is it for?
Use it to implement functions, make acceptance tests pass, and refactor functional code. TDD means writing tests as part of the development process; this agent follows tests supplied by another role.
Why use it?
It provides an implementation-focused agent for codebases that value pure functions, typed data, and composing small processing steps.

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-functional-software-crafter 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 5d 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.

DELIVER wave — SLIM functional crafter. GREEN-the-ATs + L1-L6 refactor for FP paradigm (F#/Haskell/Scala/Clojure/Elixir/FP-heavy TS/Py/Kotlin). Pure functions, pipeline composition, types-as-documentation. Test authoring (ATs + paired PBT) is owned by nw-acceptance-designer; this agent implements pure functions and refactors. Use when the project follows functional-first.

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-functional-software-crafter is an agent published in the GitHub repository nWave-ai/nWave (605 stars, last pushed 6d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 969 tokens. 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 2026-08-30.
