What is docs CLAUDE.md?

A set of instructions for developing and publishing the project-kessel documentation website. The site uses Astro and Starlight, tools for building documentation websites.

Use it when editing the documentation site, running its development or production build, placing content, or preparing changes for commit.

It defines the commands, checks, content boundaries, and commit requirements needed to keep the documentation site buildable and appropriately scoped.

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	$0.01568	$0.01568
Opus 5.5	$0.00627	$0.00627
Sonnet 5.5	$0.00314	$0.00314
Haiku 4.5	$0.00157	$0.00157

Security

Grade A, and why

docs 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.

Claude Code Configuration

@AGENTS.md

Build and Development Commands

This is an Astro/Starlight documentation site. When working in this repository:

Development workflow

Start dev server: npm run dev (serves at localhost:4321)
Build the site: npm run build (runs astro check && astro build, outputs to ./dist/)
Preview build: npm run preview (preview the built site locally)

Before committing

Always run npm run build to verify TypeScript checks and build pass
The CI pipeline runs astro check && astro build - your changes must pass this
If you get TypeScript errors, the build will fail - fix them before committing

Pre-commit hooks

This repository uses rh-multi-pre-commit for Red Hat security scanning. The hook runs automatically on commit. If you encounter hook failures unrelated to your changes, notify the team.

Claude Code Behavioral Preferences

Content placement

This repository is for public Kessel documentation only
Internal Red Hat-specific content (onboarding, hosted config, runbooks, monitoring) belongs in the separate internal docs repo published to InScope
Do not add Red Hat-specific operational content to this repository

Content creation

Use .mdx for pages needing Astro components (Aside, Tabs, CodeExamples, etc.)
Use .md for pure Markdown content
All frontmatter must include at minimum: title and description
Follow the Diataxis framework - know if you're writing tutorial, how-to, explanation, or reference

Code examples

Examples live in src/examples/ organized by topic
Use region markers for selective inclusion:
- C-style languages (Go, TS, Java): //#region name and //#endregion
- Hash-style languages (Python, Ruby, Bash): # region name and # endregion
All important code including error handling must be inside regions

TypeScript

Strict mode is enforced via astro/tsconfigs/strict
Path alias src/* maps to ./src/*
Zod schemas use .optional().default(false) for boolean fields - maintain this pattern

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.
