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 | $0.01820 | $0.01820 |
| Opus 5.5 | $0.00728 | $0.00728 |
| Sonnet 5.5 | $0.00364 | $0.00364 |
| Haiku 4.5 | $0.00182 | $0.00182 |
Grade A, and why
aix copilot-instructions.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 1mo 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

Build, Test, and Lint Commands
Prerequisites
- Go 1.25.5+ (specified in go.mod)
- Dependencies are automatically downloaded on first build
Build
go build ./cmd/aix # Build CLI binary -> ./aix
go build ./... # Build all packages (verification only)
go build -v -o aix cmd/aix/main.go # Verbose build with custom output name
First build downloads dependencies (~30 seconds). Subsequent builds are fast (<5 seconds).
Test
go test ./... # Run all tests (ALWAYS use this)
go test -v -race ./... # Verbose with race detection (CI requirement)
go test -cover ./... # With coverage report
go test ./internal/platform/... # Test specific package
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.
