riz CLAUDE.md

A project instruction file for riz, a self-hosted service that runs web and WebSocket functions on AWS Lambda using one Rust program. It defines safety rules, supported runtimes, and required checks.

In plain words
What is it for?
Use it when changing riz source code, checking Rust safety rules, running validation scripts, or reviewing which AWS event types the project supports.
Why use it?
It gives coding agents the project’s binding safety requirements and prevents changes from bypassing build, test, lint, or review gates.

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

riz 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 2d 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

riz is a self-hosted AWS Lambda + API Gateway v2 runtime in one Rust binary: six runtimes (Bun, Node.js, Python, Rust, Go, WASM), every function an MCP tool, no per-request cold start. Scope is HTTP/WS Lambdas only — SQS/SNS/S3/ EventBridge-style event sources are out of scope by decision, not omission.

Safety-critical rules (binding)

docs/SAFETY.md — NASA's Power of 10 adapted to Rust — is binding for all code compiled into the riz binary (src/, i.e. --lib --bins). Examples (examples/lambdas/*), tests, benches, and fixtures are exempt by policy.

Working rules that follow from it:

  • The enforced lint tier lives in Cargo.toml [workspace.lints] (+ clippy.toml thresholds); only the riz package opts in.
  • scripts/safety-check.sh --gate is a CI gate (prod-only zero-tolerance lints, e.g. clippy::panic).
  • scripts/safety-check.sh prints the ratchet report — violation counts may only go down. Never add a site to a ratchet lint; when a lint's count hits zero, promote it (ratchet → gate → enforced) per the protocol in docs/SAFETY.md.
  • Every unsafe block needs #[allow(unsafe_code)] at the site plus a // SAFETY: proof, one operation per block. Any other #[allow] of a safety lint needs an adjacent justification comment.
  • New code in src/: no unwrap/expect/panic!/indexing-[] on runtime data, bounded channels only, loops either provably bounded or matching the supervised event-loop contract (docs/SAFETY.md rule 2).

Build & test gates

Run before every push (CI enforces all of them):

cargo fmt --all -- --check
cargo clippy --workspace --all-targets -- -D warnings
./scripts/safety-check.sh --gate
cargo nextest run --workspace -E 'not binary(e2e_smoke_all) and not binary(template_smoke_all) and not binary(perf_regression) and not binary(chaos) and not binary(aws_conformance)'
cargo nextest run --test e2e_smoke_all   # isolated: boots the example fleet
cargo nextest run --test template_smoke_all  # isolated: scaffolds + boots all six templates
cargo nextest run --test perf_regression --no-capture  # isolated: throughput/latency floor + trend
cargo nextest run --test chaos               # isolated: deliberate fault injection
cargo nextest run --test aws_conformance     # isolated: clones + boots AWS's own Lambda samples (skips offline)
# or the whole flow in one command: scripts/validate.sh

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.

riz CLAUDE.md is an instructions file published in the GitHub repository 24X7/riz (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 1,086 tokens to every session, about $0.0054 per session on Opus 5. 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 2026-08-31.
