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 | $0.02165 | $0.02165 |
| Opus 5.5 | $0.00866 | $0.00866 |
| Sonnet 5.5 | $0.00433 | $0.00433 |
| Haiku 4.5 | $0.00216 | $0.00216 |
Grade A, and why
tradingcodex 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 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.

TradingCodex Repository Guide
Read Order And Documentation Ownership
Read in this order:
- This file for repository-wide non-negotiable rules and validation routing.
- Architecture for the codebase map, ownership, and runtime boundaries.
- Product documentation for durable behavior and rationale.
- User guide only when setup or an everyday user journey changes.
Keep each fact in one owning layer and link to it elsewhere:
| Layer | Owns |
|---|---|
docs/ |
Durable product behavior, architecture, safety, workflow, and release intent. |
guidebook/ |
Concise, task-first user instructions. |
README.md / installation.md |
Product entrypoint and installation path. |
AGENTS.md |
Repository-wide development constraints. |
Update only the owning layer unless another audience's route actually changed.
Do not mirror a rule across several documents merely to keep them textually
similar. When layers disagree, correct the owning docs/ page first.
Product Direction
TradingCodex is a thin, local-first investment layer on top of native Codex. Codex owns reasoning, research strategy, tool selection, delegation, and use of the user's available skills, plugins, apps, and MCP servers. TradingCodex owns durable investment records and deterministic boundaries for provenance, policy, approval, execution, secrets, and audit.
Do not replace native Codex capabilities with a parallel router, workflow engine, capability registry, permission system, tool-discovery protocol, agent scheduler, or provider platform. Add TradingCodex machinery only when a durable cross-session invariant or sensitive final effect cannot be handled safely by native Codex, a canonical skill bundle with a concise entrypoint, or an existing application service.
Put behavior at the first layer that can own it:
- Native Codex and user-provided capabilities.
- One canonical skill bundle with a concise
SKILL.mdentrypoint for reusable agent guidance. - A prompt for stable role identity or a safety boundary.
- An application service for durable records or deterministic enforcement.
- A hook only when enforcement must surround a native tool call.
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.
