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 | $0.01241 | $0.01241 |
| Opus 5 | $0.00620 | $0.00620 |
| Sonnet 5 | $0.00248 | $0.00248 |
| Haiku 4.5 | $0.00124 | $0.00124 |
Grade A, and why
trade-republic-mcp-server 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 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.

Project Goals
- Create a Claude Skill that automatically trades on Trade Republic in order to maximize profits.
- Use a custom MCP server to interface between Claude and Trade Republic.
General Rules
- All code must be written in TypeScript.
- Use Jest for testing.
- Use Test-Driven Development (TDD) practices:
- Write one test and prove it fails.
- Write the minimum code necessary to make the test pass.
- Refactor the code while ensuring all tests still pass.
- Follow best practices for code quality and maintainability.
- Never guess about API requests, responses or authentication; always refer to the official documentation or other reliable sources.
- Never guess about trading strategies; always refer to established financial principles.
- Document all assumptions and decisions made during development in architecture decision records (ADRs) in the folder
docs/adr.
Workflow
IMPORTANT: This workflow MUST be followed STRICTLY. It is SACRED. Following a structured workflow ensures quality, maintainability, and reduces the likelihood of errors.
GATHER DATA: Whenever you detect that something went wrong or could be improved (with the workflow, with the implementation, with the tests, with how you are following the rules, even with this document, ... anything that occurs to you), you MUST document the issue in docs/retrospective-notes.md IMMEDIATELY. This is crucial for continuous improvement and ensuring that issues are addressed promptly.
MODELS: You are allowed to use different models (opus-4.5, sonnet-4.5, haiku-4.5) for different sub-tasks (planning, implementation, review, ...). Choose the model that is best suited for the specific sub-task at hand. Some tasks require more reasoning and creativity while others just need to follow strict rules. Using the right model for the right task optimizes model costs.
Files:
- task list file:
docs/tasks.md - initial task plan files:

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.
