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 | $0.01699 | $0.01699 |
| Opus 5 | $0.00849 | $0.00849 |
| Sonnet 5 | $0.00340 | $0.00340 |
| Haiku 4.5 | $0.00170 | $0.00170 |
Grade A, and why
lcf-strain-life 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 7d 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 — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Guidance for AI agents working on this repository. This is the cross-tool companion to CLAUDE.md. Both carry the same rules, this one is the canonical source. Keep it short and precise.
Project overview
lcf is an AI-agent-native toolkit for fatigue analysis of materials. It ships
as a Python library and an MCP server, so agents can run the full analysis by
calling tools. The package covers low cycle fatigue strain-life analysis,
variable-amplitude loading, cumulative damage, notch local-strain, statistics
and design curves, and elevated-temperature creep-fatigue.
The novelty, do not lose it
The project exists to be used by AI agents first. Every capability must be reachable and useful through the MCP tools and the library API. When you add a feature, expose it as an MCP tool and keep its inputs and outputs agent friendly.
Honesty, mandatory
Be completely honest and never overpromise, in docs, claims, commit messages, and replies. Never claim a capability the code does not have. Report failures as failures. State the source for every equation and dataset, everything used must be publishable and citable. Label unvalidated results as unvalidated.
Scope, stay broad
General purpose and material agnostic. Serve many materials and many fatigue workflows, not one alloy family. The source manuscripts that seeded the equations are provenance only. Do not narrow the goal to one material.
Setup
py -3.13 -m venv .venv
./.venv/Scripts/python.exe -m pip install -e ".[mcp,dev]"
Python 3.11 or newer. No heavy new dependencies beyond numpy, scipy, pandas, matplotlib, pydantic, pyarrow, and the optional mcp SDK.
Build and test commands
./.venv/Scripts/python.exe -m pytest # full suite
./.venv/Scripts/python.exe -m pytest tests/test_fits.py -q # one module
./.venv/Scripts/python.exe -m pytest -W error::DeprecationWarning -W error::FutureWarning
Every change must keep the suite green. Scientific changes must be validated against the golden datasets already in tests, for example SAE 1137 and the ASTM E1049 rainflow example.
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.

lcf-strain-life AGENTS.md is an instructions file published in the GitHub repository dfieser/lcf-strain-life (0 stars, last pushed 14d ago), licensed MIT. It adds 1,699 tokens to every session, about $0.0085 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.
