When updating pyproject.toml (lint/type/dependency config), keep changes minimal and future-safe: enable/disable rules deliberately, scope suppressions to the smallest scope, avoid broad “select everything” patterns that can introduce unintended auto-fixes, remove redundant settings, and bound dependency versions.

Guidelines:

• Prefer targeted suppression over global ignores: use # noqa: <code> / noqa: <rule> on the specific line; avoid broad ignorelist entries unless truly pervasive.
• Don’t enable select = ["ALL"] without scoping how fixes are applied. If you must opt into many rules, ensure auto-fixing cannot silently change semantics or readability by pulling in newly-added rules after version bumps.
• Remove redundant mypy/typing flags when the stricter umbrella option already covers them.
• Keep dependency constraints bounded (upper bounds for major versions) so upgrades don’t silently jump compatibility boundaries.

Example (lint config):

[tool.ruff.lint]
# Prefer explicit lists or ALL only with careful fix scoping.
select = ["ALL"]
# AND ensure you only fix the rules you explicitly trust:
# fixable = ["F", "E", "W"]  # example: opt-in only

[tool.flake8-builtins]
# Prefer per-line suppression over global ignores:
# "id" should usually be handled with:  some_var = id(...)  # noqa: A002
ignorelist = []

Example (mypy config):

[tool.mypy]
strict = true
# Avoid redundant flags like strict_bytes if strict already implies it.
# strict_bytes = true  # remove

Example (dependency bounds):

dependencies = [
  "langgraph>=0.6.0,<1.0.0",
]
