Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

Smithplates 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 24d 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Smithplates

Smithy codegen plugin for SQL schema/migration and HTTP service/client output. Bundled templates today: Python (SQL + FastAPI server + HTTPX/HTTPX2 client) and TypeScript (HTTP client via axios or fetch), plus bounded Rust async reqwest JSON clients.

Conventions

Follow .cursor/rules/ — start with smithplates-build.mdc and code-design.mdc. Update user docs under docs/usage/ and contributor docs under docs/contributing/ when behavior or integration steps change.

Keep Smithplates self-contained and domain-neutral. Do not reference downstream repositories, their names, or their issue/PR numbers in Smithplates code, tests, documentation, changelogs, commit messages, or pull requests; describe motivations and examples as generic consumer requirements instead.

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.
