What is runx CLAUDE.md?

Instructions for working on the runx software project, including its architecture, development commands, release practices, and specification workflow. It defines which parts of the system own contracts, parsing, execution, and other responsibilities.

Use it when implementing or reviewing runx changes, following a scafld specification, checking the Rust and TypeScript parts, or running the project's type, dependency-graph, and verification commands.

It helps contributors follow the project's boundaries and avoid duplicating trusted behavior in the wrong language or package. It also points to focused checks for validating changes.

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	$0.00056	$0.00056
Opus 5.5	$0.00022	$0.00022
Sonnet 5.5	$0.00011	$0.00011
Haiku 4.5	$0.00006	$0.00006

Security

Grade A, and why

runx 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 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.

What it actually says

Claude Code

Read AGENTS.md first for architecture, implementation, validation and the scafld lifecycle. Follow CONVENTIONS.md for coding standards. Keep shared agent instructions in those canonical guides.

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.
