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 | $0.02427 | $0.02427 |
| Opus 5 | $0.01213 | $0.01213 |
| Sonnet 5 | $0.00485 | $0.00485 |
| Haiku 4.5 | $0.00243 | $0.00243 |
Grade A, and why
oh-my-claudian 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 9d 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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Project
Claudian is an Obsidian plugin that embeds provider-backed coding agents in a sidebar and inline-edit flow. Claude is the default provider. The built-in selectable providers are Claude, Codex, Cursor, Grok, OMP (Oh My Pi), OpenCode, and Pi; ACP is shared transport infrastructure, not a selectable provider. All providers plug into the same conversation model through Conversation.providerId and opaque provider-owned providerState.
Do not assume provider parity. Check each provider's capabilities.ts, registration.ts, and UI config before wiring shared behavior.
Scope Guides
- Before editing a scoped area, read its nearest scoped guide:
src/app/AGENTS.mdsrc/core/AGENTS.mdsrc/features/chat/AGENTS.mdsrc/providers/claude/AGENTS.mdsrc/providers/codex/AGENTS.mdsrc/providers/cursor/AGENTS.mdsrc/providers/grok/AGENTS.mdsrc/providers/omp/AGENTS.mdsrc/providers/opencode/AGENTS.mdsrc/providers/pi/AGENTS.mdsrc/style/AGENTS.md
AGENTS.md Maintenance
- AGENTS.md is execution context for agents, not general documentation. Keep only repository- or scope-specific information that a capable agent would not reliably know; every statement must change implementation, review, or verification behavior.
- Keep repository-wide rules here; put local ownership, dependencies, invariants, failure modes, verification, and active decisions in the narrowest scoped guide that governs them.
- Do not duplicate inherited guidance or silently contradict it. State a necessary local exception and its rationale explicitly.
- Omit tours, ordinary implementation details, temporary status, and general engineering advice.
- Record a decision only when it is active, surprising from the code, expensive to reverse, and reflects a real tradeoff. State the decision, rationale, and any concrete reconsideration condition; use Git history as the archive.
CLAUDE.mdfiles should import the nearestAGENTS.md; do not duplicate shared guidance there.
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.

oh-my-claudian AGENTS.md is an instructions file published in the GitHub repository lee259/oh-my-claudian (13 stars, last pushed today), licensed MIT. It adds 2,427 tokens to every session, about $0.0121 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.
