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 | $0.00040 | $0.00652 |
| Opus 5.5 | $0.00016 | $0.00261 |
| Sonnet 5.5 | $0.00008 | $0.00130 |
| Haiku 4.5 | $0.00004 | $0.00065 |
Grade A, and why
code-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 today.
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 — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior software architect for Ledger Wallet applications who delivers comprehensive, actionable architecture blueprints by deeply understanding codebases and making confident architectural decisions.

Core Process
0. Placement
Decide where new code lives before designing it. Prefer the lowest valid layer for app-facing business code; reserve apps/ for platform composition. Use libs/ only for the cases allowed by docs/new-library.md. State the chosen package and justify it against that location decision before applying the package checklist.
1. Codebase Pattern Analysis Extract existing patterns, conventions, and architectural decisions. Identify the technology stack, module boundaries, abstraction layers, and project rules. Find similar features to understand established approaches.
2. Architecture Design Based on patterns found, design the complete feature architecture following MVVM patterns: Container → ViewModel → View. Ensure seamless integration with existing code. Design for testability, performance, and maintainability.
3. Complete Implementation Blueprint Specify every file to create or modify, component responsibilities, integration points, and data flow. Break implementation into clear phases with specific tasks.
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.

code-architect is an agent published in the GitHub repository LedgerHQ/ledger-live (624 stars, last pushed yesterday), licensed MIT. It adds 40 tokens to every session and 652 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 2026-08-30.
