| - One concern per PR. Keep unrelated formatting/import churn out of feature PRs. | ||
| - Keep the first version of a PR minimal; defer optimizations and edge cases to follow-ups. | ||
| - Commit messages explain the *what* and *why*, not line-by-line implementation. Be as succinct as possible. | ||
| - The Apache License header is required on every new source file (enforced by `./dev/check-license` and pre-commit). |

The license header isn't enforced by pre-commit as far as I confirmed.
| - Formatting and linting are enforced by `ruff` via `prek` (pre-commit): line length **130**, double-quoted strings, isort with `pyiceberg`/`tests` as first-party. Run `make lint` — ruff autofixes most issues. | ||
| - Full type annotations are required (`mypy` runs in strict mode: `disallow_untyped_defs`, `no_implicit_optional`, `warn_unused_ignores`). Avoid Any types. | ||
| - Docstrings follow the project's pydocstyle config; one-line summaries on public functions. No personal pronouns in comments. | ||
| - Define typed exceptions in `pyiceberg/exceptions.py` and raise the most specific one; don't raise bare `Exception`. |

nit: ValueError is widely used in this project. We could rephrase it like this:
Use domain-specific exceptions from pyiceberg/exceptions.py for Iceberg-specific error conditions. For invalid arguments/values, ValueError is acceptable. Don't raise bare Exception.

Rationale for this change
Our AGENTS.md just talks about the security model. We get a non-trivial amount of AI activity on this repo and our AGENTS.md should reflect some basic assumptions we want for those PRs.
A lot of this was inspired by Iceberg AGENTS.md.
This is just meant to be an initial version with some thoughts that I've seen and some of the basic architecture (as seen in the Iceberg AGENTS.md)
Are these changes tested?
Just Markdown.
Are there any user-facing changes?
No.
