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 | $0.01380 | $0.01380 |
| Opus 5.5 | $0.00552 | $0.00552 |
| Sonnet 5.5 | $0.00276 | $0.00276 |
| Haiku 4.5 | $0.00138 | $0.00138 |
Grade A, and why
dataprof 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 5d 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Guidance for AI coding agents (Claude Code, Codex, Cursor, ...) working in this repository. Humans should start from README.md and docs/CONTRIBUTING.md; this file is the condensed, agent-oriented version and the single source of truth for agent instructions.
What this project is
dataprof is a local, deterministic data profiling and quality assessment
library: a Rust workspace with a PyO3-based Python package on top. The release
surface is Rust library crates plus Python wheels — there is no CLI binary.
It profiles data and reports on it; it does not transform, clean, or move data.
Keep changes within that identity.
examples/ are executable docs: CI runs them, so keep them working.
Build, test, lint
Prerequisites: Rust 1.96+, Python 3.11+, uv.
Local development runs on CPython 3.15, pinned in .python-version, which uv
reads and installs on its own; ty still checks against the 3.11 floor.
1.96 is the MSRV (rust-version in Cargo.toml). CI lints and tests on the
toolchain pinned in rust-toolchain.toml, and rustup reads that file, so plain
cargo in this checkout runs the same compiler as CI. Clippy gates the build
with -D warnings and every Rust release adds lints; a cargo +<version>
command or a RUSTUP_TOOLCHAIN variable overrides the file, so when clippy
disagrees with CI, check rustc --version first.
The MSRV itself is enforced by compilation, not by the declaration: the MSRV Compile Gate job runs cargo check --locked --lib over every published feature
graph on 1.96. Reproduce it with
RUSTUP_TOOLCHAIN=1.96 uv run --no-project python .github/scripts/msrv_check.py. If a change needs
a newer standard-library API, raising the MSRV is a deliberate separate change —
see docs/CONTRIBUTING.md.
uv sync # install the Python dev environment
uv run maturin develop # build + install the local Python extension
# Focused tests (prefer these; match the command to your change)
cargo test -p dataprof-core
cargo test -p dataprof-python
uv run pytest python/tests/test_python_api.py -q
# Gates that CI enforces — run before committing
cargo fmt --all
cargo clippy --all --all-targets -- -D warnings

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.

dataprof AGENTS.md is an instructions file published in the GitHub repository AndreaBozzo/dataprof (31 stars, last pushed today), licensed MIT. It adds 1,380 tokens to every session, about $0.0055 per session on Opus 5.5. 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 2026-08-30.
