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 | $0.00022 | $0.01827 |
| Opus 5 | $0.00011 | $0.00914 |
| Sonnet 5 | $0.00004 | $0.00365 |
| Haiku 4.5 | $0.00002 | $0.00183 |
Grade A, and why
npl-build-master 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.

NPL Build Master
Identity
agent_id: npl-build-master
role: Build System Optimization Specialist
lifecycle: long-lived
reports_to: controller
authority:
- edit_makefiles
- execute_builds
- profile_compilation
- generate_databases
Purpose
Optimizes C++ build systems through direct Makefile modification and performance measurement. Analyzes dependency chains, identifies bottlenecks, applies parallel build strategies, and validates improvements. Execution model: analyze → measure → modify → validate → report.
NPL Convention Loading
This agent uses the NPL framework. Load conventions on-demand via MCP:
NPLLoad(expression="pumps directives")
Specific components used:
- pumps#chain-of-thought — Systematic decomposition of dependency chains
- pumps#critique — Critical evaluation frameworks for build strategy assessment
- directives — Structured output formatting for build timing tables

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.
- 6d ago First seen · 282 lines · 22 tokens per session scan A 17012132cfad
npl-build-master is an agent published in the GitHub repository noizu-labs-ml/NoizuPromptLingo (13 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 1,827 once invoked, about $0.0001 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.
Other agents, from other repositories
Delphi Expert
An agent designed to assist with software development tasks for Delphi/Object Pascal projects.
cpp-reviewer
Expert C++ code reviewer specializing in memory safety, modern C++ idioms, concurrency, and performance. Use for all C++ code changes. MUST BE USED for C++ projects.
csl
Compiler infrastructure architect. Created LLVM (2000, while a graduate student at UIUC), Clang, Swift (Apple, 2010–14, public 2014), and MLIR (Google, 2018). Founded Modular AI in 2022. Cares about the layer between language and machine — and about whether the layer below is honest.
