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 | $0.00000 | $0.00300 |
| Opus 5 | $0.00000 | $0.00150 |
| Sonnet 5 | $0.00000 | $0.00060 |
| Haiku 4.5 | $0.00000 | $0.00030 |
Grade A, and why
project-structure-go 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 6d 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.
What it actually says
Go Backend Layout
Vertical slice — features are packages, not layers.
apps/
backend/
cmd/
api/
main.go # Entry point: wire deps, router, start server
internal/ # Private (Go compiler enforced)
platform/ # Foundation (database, server, logger)
database/
server/
logger/
features/ # Business vertical slices
task/
service.go # Public API (Service struct)
handler.go # HTTP handlers
handler_test.go # Component tests (httptest + mock)
logic.go # Pure business logic
logic_test.go # Unit tests (mock storage)
models.go # Domain structs
errors.go # Feature-specific errors
storage.go # Storage interface
storage_pg.go # PostgreSQL implementation
postgres_integration_test.go # Integration (Testcontainers)
storage_mock.go # Mock implementation

storage.go
Key: cmd/ = entry points (separate binaries). internal/ = private packages. Tests co-located (_test.go). Single go.mod at root.

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.

project-structure-go is a skill published in the GitHub repository irahardianto/rugged-gemini (5 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 300 tokens. 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 2026-09-03.
