Aiobotocore

Scope: botocore-sync only. The skill formerly known as bump-version was renamed and scoped down: contributors no longer bump aiobotocore/__init__.py or edit CHANGES.rst per PR. Both are handled at release time by /aiobotocore-bot:draft-release.

Update the botocore dependency bounds in pyproject.toml and refresh uv.lock. That's it — two files, one mechanical change. Use this so the bound calculation (lower-bound rule, upper-bound rule) and the dual-package uv lock step are both correct without hand-editing.

Arguments

• --mode=no-port|port (required)
• --target=<version> (required): the target botocore version, e.g. 1.42.89
• --lower-bound=<version> (optional, port mode only): the EARLIEST botocore version that shipped the breaking change requiring this port. Defaults to --target if omitted, but the caller should set this explicitly when the classifier identified the change as shipping in an earlier version of the $FROM..$TO range. Example: classifier finds the new auth_scheme_preference arrived in 1.42.90 and the target is 1.42.91 — pass --lower-bound=1.42.90 so users on 1.42.90 still satisfy the spec.

Step 1: Update pyproject.toml bounds

• Locate the botocore dependency line (e.g. botocore >= 1.42.79, < 1.42.90).
• New upper bound is always one patch above --target: if target is 1.42.89, upper is < 1.42.90.
• --mode=no-port: keep the lower bound unchanged, update the upper bound.
• --mode=port: set lower bound to --lower-bound (or --target if not provided), set upper bound as above. Lifting the lower bound past the version that introduced the breaking change is wrong — it locks out users on the in-between version that already has the new feature.
• Do the same for the boto3 dependency line if it's pinned (same range).

Step 2: Run uv lock

uv lock --upgrade-package boto3 --upgrade-package botocore

The dual --upgrade-package is intentional: boto3 and botocore are tightly version-coupled upstream and a stale boto3 against a freshly-bumped botocore produces confusing test failures (#1571 review feedback). Always upgrade both together so the lockfile reflects a coherent pair.

Step 3: Output

Print the new bound (e.g. botocore >= 1.42.90, < 1.42.92). The caller is responsible for committing (via mcp__github_file_ops__commit_files) — this skill only mutates files.

What NOT to do

• Don't bump aiobotocore/__init__.py. The next release-PR (drafted by /aiobotocore-bot:draft-release) will compute the right bump (PATCH for no-port sync, MINOR if a feature also landed in the window) and write it.
• Don't edit CHANGES.rst. The release flow synthesizes the changelog from merged PRs in the release window; just give the PR a clean title (the unified bump botocore dependency specification to support "botocore >= X, < Y" convention is the expected wording).
• Don't try to detect "unreleased" state. The release flow sees the full window and handles it.

Honesty

If pyproject.toml's botocore line cannot be parsed, abort with an explicit error. Don't silently produce a broken pyproject.
