nw-forge

nw-forge is a skill for Claude Code from nWave-ai/nWave. It costs 44 tokens per session (596 once invoked), scanned A, original, MIT.

A five-phase workflow for creating or checking a specialized AI agent: analyze, design, create, validate, and refine.

In plain words
What is it for?
Use it to specify new agents, choose their tools and structure, create supporting skills, and run a validation checklist before refinement.
Why use it?
It gives agent development a repeatable process for defining one responsibility, avoiding overlap, and checking the result against specific requirements.

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-forge 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 1mo 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-FORGE: Create Agent (V2)

Wave: CROSS_WAVE Agent: Zeus (nw-agent-builder)

Overview

Create a new agent using research-validated v2 approach: focused core (200-400 lines) with Skills for domain knowledge.

  1. ANALYZE — Identify single clear responsibility, check overlap with existing agents, classify type, determine minimum tools needed. Gate: responsibility defined, no overlap, classification chosen.
  2. DESIGN — Select design pattern, define role and divergent principles, plan Skills extraction, draft frontmatter. Gate: pattern selected, principles drafted, frontmatter ready.
  3. CREATE — Write agent .md using template. Workflow must be numbered task list. Create Skill files if domain knowledge exceeds 50 lines. Gate: agent file written, line count under 400.
  4. VALIDATE — Run 14-point validation checklist. Check for anti-patterns. Verify workflow is numbered task list, not prose. Gate: all 14 items pass, zero anti-patterns.
  5. REFINE — Address validation failures. Add instructions only for observed failure modes. Re-measure and re-validate. Gate: all items pass, line count reported.

Agent Invocation

@nw-agent-builder

Execute *forge to create {agent-name} agent.

Configuration:

  • agent_type: specialist | reviewer | orchestrator
  • design_pattern: react | reflection | router | planning | sequential | parallel | hierarchical

Success Criteria

  • Agent definition under 400 lines (wc -l)
  • Official YAML frontmatter format (name, description, tools, maxTurns)
  • 11-point validation checklist passes
  • Only divergent behaviors specified (no Claude defaults)
  • 3-5 canonical examples included
  • Domain knowledge extracted to Skills if >50 lines
  • No aggressive language (no CRITICAL/MANDATORY/ABSOLUTE)
  • Safety via platform features (frontmatter/hooks), not prose

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.
