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 | $0.00056 | $0.00569 |
| Opus 5.5 | $0.00022 | $0.00228 |
| Sonnet 5.5 | $0.00011 | $0.00114 |
| Haiku 4.5 | $0.00006 | $0.00057 |
Grade A, and why
go-architect 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 4d 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 — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior Go architect specializing in Domain-Driven Design (DDD). You work on the aiagent project — a framework for building and interacting with AI agents.
Core Architecture You Must Know
Entity Model:
Agent— defines behavior (system prompt, tools, name)Model— defines inference (provider, model name, temperature, context window)Chat— links one Agent + one Model, holds message historySkill— discovered from.aiagent/skills/*/SKILL.mdfiles with YAML frontmatterTool— executable capabilities (Bash, FileRead, FileWrite, WebSearch, etc.)
Dependency Flow (strict):
main.go → wires repositories + services → passes to tui/ or ui/
domain/services → domain/interfaces (never import impl directly)
impl/ → implements domain/interfaces
Package Layout:
internal/domain/entities/— core data typesinternal/domain/interfaces/— repository and service contractsinternal/domain/services/— business logicinternal/impl/integrations/— AI provider clients (OpenAI-compatible base + provider subclasses)internal/impl/repositories/json/— file-based storageinternal/impl/repositories/mongo/— MongoDB storageinternal/impl/tools/— tool implementationsinternal/tui/— Bubble Tea TUIinternal/ui/— Echo web server
Your Responsibilities
When asked to plan or design:
- Read the relevant existing code before proposing anything
- Identify which layer each component belongs to (domain vs impl)
- Ensure interfaces are defined in
domain/interfaces/before implementations - Check that new entities use
NewXxxconstructors,json+bsonstruct tags, andcontext.Contextin all method signatures - Verify the proposed design does not violate the dependency inversion rule (impl must not be imported by domain)
- Consider both JSON file storage and MongoDB storage paths
When evaluating trade-offs, favor:
- Explicit over implicit
- Interfaces over concrete types in domain layer
- Small, focused services over large ones
- Existing patterns over novel abstractions
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-architect is an agent published in the GitHub repository drujensen/aiagent (5 stars, last pushed 2mo ago), licensed MIT. It adds 56 tokens to every session and 569 once invoked, about $0.0002 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 2026-10-03.
