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 | $0.00760 | $0.00760 |
| Opus 5.5 | $0.00304 | $0.00304 |
| Sonnet 5.5 | $0.00152 | $0.00152 |
| Haiku 4.5 | $0.00076 | $0.00076 |
Grade A, and why
fieldflow AGENTS.md scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
Commit messages in this repo use short imperative summaries (e.g., `add proxy filter logging`). Group related changes together and include follow-up detail in the body only when necessary. Pull requests should describe b How it starts

Repository Guidelines
Project Structure & Module Organization
Core runtime code lives in fieldflow/, exported as the fieldflow package that builds FastAPI tooling on top of OpenAPI specs. MCP-specific utilities and the CLI wrapper stay in fieldflow_mcp/. Specs for local experimentation sit in examples/, while tests/ holds pytest-based coverage for the HTTP proxy and MCP integration. Tooling metadata such as pyproject.toml and requirements.txt define install targets and extras (.[dev], .[mcp]).
Current Product Scope
FieldFlow currently supports OpenAPI-described REST APIs exposed as HTTP tool endpoints and the same generated OpenAPI tools exposed through MCP. It does not yet wrap arbitrary existing MCP servers. If work moves toward existing MCP server proxying, keep it in a dedicated design/feature PR and prefer MCP tools with structured outputSchema.
Build, Test, and Development Commands
Bootstrap everything at once with python -m venv .venv && source .venv/bin/activate && python -m pip install --upgrade pip && python -m pip install -e '.[dev,mcp]'. Launch the HTTP proxy via fieldflow serve-http --reload and switch to the MCP bridge with fieldflow-mcp --transport stdio. Run the full suite through pytest, or narrow focus using pytest tests/test_app.py -k fields during debugging. The CI-equivalent local check set is ruff check fieldflow fieldflow_mcp tests, black --check fieldflow fieldflow_mcp tests, mypy fieldflow fieldflow_mcp, pytest, python -m build, and python -m pip check.
Coding Style & Naming Conventions
Python modules follow 4-space indentation, type hints, and descriptive snake_case names (tooling.py, StubAsyncClient). Run ruff check fieldflow fieldflow_mcp tests for linting and black --check fieldflow fieldflow_mcp tests for formatting validation; use black fieldflow fieldflow_mcp tests only when formatting is needed. Keep imports ordered (stdlib, third-party, local) and prefer explicit re-exports in fieldflow/__init__.py for public APIs. Use mypy fieldflow fieldflow_mcp when touching type-heavy parsing code.
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.

fieldflow AGENTS.md is an instructions file published in the GitHub repository guillaumegay13/fieldflow (110 stars, last pushed 3mo ago), licensed MIT. It adds 760 tokens to every session, about $0.0030 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
