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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.01919 |
| Opus 5.5 | $0.00013 | $0.00768 |
| Sonnet 5.5 | $0.00006 | $0.00384 |
| Haiku 4.5 | $0.00003 | $0.00192 |
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 2mo 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 10d ago), licensed MIT. It adds 32 tokens to every session and 1,919 once invoked, about $0.0001 per session on Opus 5.5. 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.
