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 | $0.01222 | $0.01222 |
| Opus 5.5 | $0.00489 | $0.00489 |
| Sonnet 5.5 | $0.00244 | $0.00244 |
| Haiku 4.5 | $0.00122 | $0.00122 |
Grade A, and why
avalonia-extensions AGENTS.md 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 20d 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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AI Assistant Guidelines
⚠️ REQUIRED: Session Pre-flight Check
Before starting any task, run this check:
ls .claude/local/
If the output contains only README.md (no other files), or if .vscode/ is missing, you must run the worktree setup script before doing anything else:
bash scripts/setup-worktree.sh
On Windows: pwsh scripts/setup-worktree.ps1
This copies gitignored local config (personal commands, .vscode/ settings) from the main worktree. Skipping it means you'll be missing developer-specific tooling and commands for this session.
Development baseline initialization
At the start of every new agent session, after local configuration setup and before implementation, always ask once whether the user wants a full clean development baseline set, including for non-visual tasks. Do not repeat the question within the same session.
If approved, run ./devtest visual --initialize-local-baselines on the clean
starting revision. This captures non-native personal images without comparisons
or WinUI identity checks, and never writes tracked images. If the command
warns that LocalBaselines is non-empty, surface the overwrite confirmation
through the user-question tool. Never automatically answer or pipe y unless
the user explicitly approves overwriting the existing set.
Never initialize from already modified code without explicit user approval;
use a separate ordinary test run to check native images and regressions.
Do not copy personal baselines automatically between worktrees.
Note: This file has been superseded by more comprehensive documentation in the

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.

avalonia-extensions AGENTS.md is an instructions file published in the GitHub repository Devolutions/avalonia-extensions (84 stars, last pushed 15d ago), licensed MIT. It adds 1,222 tokens to every session, about $0.0049 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.
