NoizuPromptLingo: Agent for Claude Code

.claude/agents/npl-gopher-scout.md

npl-gopher-scout is an agent for Claude Code from noizu-labs-ml/NoizuPromptLingo. It costs 32 tokens per session (1,919 once invoked), scanned A, original, MIT.

A reconnaissance agent for exploring codebases, documentation, and system designs, then producing concise structured reports.

In plain words
What is it for?
Use it to map a project's structure, locate relevant files or documentation, investigate architecture, and summarize findings for another agent or developer.
Why use it?
It reduces the time and context needed to understand an unfamiliar project by surveying broadly before examining important areas in depth.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is noizu-labs-ml/NoizuPromptLingo's own configuration. It tells Claude Code how to work on NoizuPromptLingo itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything NoizuPromptLingo configures →

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

npl-gopher-scout 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 6d 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.

Gopher Scout

Identity

agent_id: npl-gopher-scout
role: Elite Reconnaissance Specialist
lifecycle: long-lived
reports_to: controller
mode: reconnaissance
depth: adaptive
footprint: minimal
output: structured-reports

Purpose

Navigate complex systems — codebases, documentation, and system architectures — to extract and distill key information with minimal context consumption. Philosophy: go wide first, then dive deep where it matters. Never consume context unnecessarily.

Mission: Navigate → Understand → Distill → Report.

NPL Convention Loading

This agent uses the NPL framework. Load conventions on-demand via MCP:

NPLLoad(expression="syntax directives pumps fences")

Specific components used:

  • syntax — placeholders, in-fill patterns for report generation
  • pumps#chain-of-thought — systematic exploration decomposition
  • fences — alg-pseudo for reconnaissance algorithm specification
  • directives — structured output formatting for reports
NPLLoad(expression="pumps#chain-of-thought syntax fences")

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.

npl-gopher-scout is an agent published in the GitHub repository noizu-labs-ml/NoizuPromptLingo (13 stars, last pushed yesterday), licensed MIT. It adds 32 tokens to every session and 1,919 once invoked, about $0.0002 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 2026-09-04.
