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 | $0.00449 | $0.00449 |
| Opus 5 | $0.00225 | $0.00225 |
| Sonnet 5 | $0.00090 | $0.00090 |
| Haiku 4.5 | $0.00045 | $0.00045 |
Grade A, and why
turbo AGENTS.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 8d 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
Turbo
Turbo is a modular collection of agentic coding skills with sibling editions for Claude Code and Codex. Skills connect into larger pipelines like $finalize and $review-pr. See README.md for the full overview and dependency graph.

claude/ # Claude Code edition (parallel tree)
Each skill is self-contained. Skills compose other skills to any depth via $skill-name invocations. The key distinction is between analysis skills (return structured findings without acting) and workflow skills (compose analysis skills and act on results).
For Codex skill conventions, see codex/SKILL-CONVENTIONS.md. General skill-authoring principles live in codex/skills/create-skill/references/, split by topic and indexed in that skill's SKILL.md.
Key Files
~/.turbo/config.json— User-level configuration. Top-leveloracleis shared. Per-edition state lives undercodex.{excludeSkills, lastUpdateHead, configVersion, sharedClaudeAutoMemory}; the parallelclaude.*object is present when the Claude edition is also installed.~/.turbo/repo/— Local clone of the upstream turbo repo (skill source for install/update)~/.agents/skills/— Installed Codex skills
When working inside codex/, also see codex/AGENTS.md for edition-specific rules.
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.
