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 | $0.00311 | $0.00311 |
| Opus 5.5 | $0.00124 | $0.00124 |
| Sonnet 5.5 | $0.00062 | $0.00062 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
orbital-express 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 specifics
- Skills live in
.claude/skills/. They auto-invoke when a task matches their description, or run them explicitly (e.g./create-feature). Prefer the skill for any task it covers. - Nested context:
app/CLAUDE.md(if present) loads automatically when you work insideapp/. Keep deep, area-specific notes there rather than bloating this file. - Full rulebook:
docs/conventions.txtis the authoritative, detailed rules — read it on demand for anything ambiguous;AGENTS.mdsummarizes the non-negotiables. - Personal settings go in
.claude/settings.local.json(gitignored). Shared, committed settings go in.claude/settings.json. - Docs stay in sync (enforced): a committed PostToolUse hook (
.claude/hooks/doc-sync-reminder.py, wired in.claude/settings.json) fires whenever you edit any documentation surface (documentation.html,README.md,docs/*,AGENTS.md,CLAUDE.md,database/schema.sql, anySKILL.md) and reminds you to reconcile the others. Follow thesync-docsskill — a doc change isn't done until the parallel surfaces and the relevant skill(s) agree.
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.

orbital-express CLAUDE.md is an instructions file published in the GitHub repository Hackbyrd/orbital-express (15 stars, last pushed 2mo ago), licensed MIT. It adds 311 tokens to every session, about $0.0012 per session on Opus 5.5. 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 2026-08-30.
