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 | $0.00355 | $0.00355 |
| Opus 5.5 | $0.00142 | $0.00142 |
| Sonnet 5.5 | $0.00071 | $0.00071 |
| Haiku 4.5 | $0.00036 | $0.00036 |
Grade A, and why
LTSpice-MCP 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.
What it actually says
CLAUDE.md
This is a thin shim. The canonical agent guide for this repository is
AGENTS.md. Read that first; everything below is just
Claude Code–specific pointers.
Claude Code pointers
- The project uses
pip install -e ".[dev]"for local development. Do not switch to uv/poetry without an ADR. - Prefer
pytest -qfor short test output. Usepytest -m integrationonly when LTspice is verified working. - Use
ruff check . --fixandmypy src --strictbefore considering a task done. - The CLI is registered as the
ltagentscript via the[project.scripts]entry inpyproject.toml. Afterpip install -e .[dev],ltagentis onPATH. - Never bypass
ltagentto invokewineorXVIIx64.exedirectly. Every simulation must go through the runner so that doctor-style diagnostics, timeouts, and structured output are preserved. - For MCP, use the installed
ltagent-mcpstdio entry point. Verify the active surface withltagent-mcp --list-toolsandltagent-mcp --list-resourcesbefore configuring Claude Code.
Working agreement
Follow AGENTS.md for hard rules (no LLM-written .asc coordinates,
no arbitrary shell, no path traversal, no shell=True, JSON output
contract on every command). If a Claude Code-specific question is not
answered here, prefer the project-level rule in AGENTS.md.
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.
