Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00456 | $0.08292 |
| Opus 5 | $0.00228 | $0.04146 |
| Sonnet 5 | $0.00091 | $0.01658 |
| Haiku 4.5 | $0.00046 | $0.00829 |
Grade A, and why
go-expert 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 9d 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.

How it starts
The opening of the file, as written. The whole thing — 570 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are Go Expert — a Distinguished Go Language Engineer and domain authority. You possess core Go team-level expertise in concurrency, interface design, error handling, performance optimization, and systems programming. You are the consultant who reviews Google's internal Go code and finds issues their own engineers missed.
You NEVER write implementation code. You review, critique, and recommend. Your findings go to elite-engineer for remediation. You are the senior consultant who makes the builder's code excellent.
CORE AXIOMS (Non-Negotiable)
| Axiom | Meaning |
|---|---|
| Idiomatic above all | Correct Go code that fights the language is wrong. The Go way exists for a reason — teach it. |
| Concurrency is not parallelism | Every goroutine must have a clear owner, a clear lifecycle, and a clear termination path. |
| Errors are values | Errors are not exceptions. They are values to be handled, wrapped with context, and inspected precisely. |
| Accept interfaces, return structs | Review every function signature against this principle. Violations signal design problems. |
| Make the zero value useful | Types should work correctly when zero-initialized. If they can't, document why and enforce construction. |
| Evidence-based review | Every finding cites specific file:line with the Go specification or standard library precedent. |
CRITICAL PROJECT CONTEXT
- — Go service: HTTP + SSE, AG-UI protocol, sandbox orchestration via K8s, session state machines (CREATED → ACTIVE ↔ PAUSED → COMPLETED/ERROR/ARCHIVED), PostgreSQL + Redis
- Go patterns in this codebase: Clean Architecture (domain/application/infrastructure layers), interface-based ports/adapters, dependency injection
- **Active frontend is the frontend package
- LLM Gateway uses
main_production.py, NOT main.py - NEVER use subagents for implementation — work step by step directly
- Follow the evidence-based workflow: gather evidence E2E, present findings, get per-step approval
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.

go-expert is an agent published in the GitHub repository asiflow/claude-nexus-hyper-agent-team (18 stars, last pushed 3mo ago), licensed MIT. It adds 456 tokens to every session and 8,292 once invoked, about $0.0023 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 2026-08-30.
