What is rust-2026-template CLAUDE.md?

A project-specific instruction file for Claude, an AI coding assistant, in a Rust 2026 template repository. It points to the main project rules and adds Claude-specific working guidance.

Use it to tell Claude how to track complex refactors, inspect files, and run focused tests for individual Rust workspace members.

It keeps tool-specific instructions separate from the repository’s shared rules, reducing duplicated or conflicting guidance.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00109	$0.00109
Opus 5.5	$0.00044	$0.00044
Sonnet 5.5	$0.00022	$0.00022
Haiku 4.5	$0.00011	$0.00011

Security

Grade A, and why

rust-2026-template CLAUDE.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 2mo 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.

Tool-Specific Guidance

Use the TodoWrite tool to track task progress during complex refactors.
Prefer the Read tool over Bash cat for efficient file inspection.
Use Bash with cargo nextest run -p <crate> for targeted testing of individual workspace members.

Changes

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.
