Behavior-Driven Development with pytest-bdd. ALWAYS invoke when writing Gherkin scenarios, pytest-bdd step definitions, or any BDD acceptance tests. Never write feature files without this skill loaded.
Commit message convention. ALWAYS invoke before creating any git commit or writing a commit message. Never format a commit without this skill loaded.
Domain-Driven Design tactical patterns. ALWAYS invoke when implementing aggregates, entities, value objects, repositories, or domain events in Python. Prevents common DDD mistakes (anemic models, multi-aggregate transactions).
Retrieves up-to-date documentation, API references, and code examples for any developer technology. Use this skill whenever the user asks about a specific library, framework, SDK, CLI tool, or cloud service -- even for well-known ones like React, Next.js, Prisma, Express, Tailwind, Django, or Spring Boot. Your training data may not reflect recent API changes or version updates. Always use for: API syntax questions, configuration options, version migration issues, "how do I" questions mentioning a library name, debugging that involves library-specific behavior, setup instructions, and CLI tool usage. Use even when you think you know the answer -- do not rely on training data for API details, signatures, or configuration options as they are frequently outdated. Always verify against current docs. Prefer this over web search for library documentation and API details.
Git branch comparison and diff workflows using worktrees. ALWAYS invoke when comparing branches, diffing synth output, or needing to work with multiple branches simultaneously. Never stash or checkout to compare — use worktrees.
AWS Lambda Powertools Logger gotchas and patterns. ALWAYS invoke when working with Powertools Logger, Lambda logging, or structured logging. Reserved key collisions cause runtime KeyErrors — do not answer from memory.

SOP for AWS credential management with awsume. You MUST invoke this before running any awsume command or managing AWS credentials — MUST NOT guess flags or syntax from memory.
Constraints:
awsume -l to list available profiles if the target profile is unknownawsume -l more for extended details including account IDs (slower, calls STS)Constraints:
fish -c when running in a fish shell contextaws sts get-caller-identity; and in fish shell# Assume profile and verify
fish -c 'awsume <profile>; and aws sts get-caller-identity'
# Assume and run a command
fish -c 'awsume <profile>; and <aws-command>'
awsume -l # list all profiles
awsume -l more # list with account IDs (calls STS, slower)
awsume -u # unset current AWS env vars
awsume -r <profile> # force refresh credentials
awsume -s <profile> # show export commands for another shell session

--region <region> <profile> | Override region |
--auto-refresh / -a | Auto-refresh credentials in background |
--kill-refresher / -k | Stop auto-refresh |
--source-profile | Specify source profile for role-arn assume |
--external-id | Pass external ID for cross-account roles |
--mfa-token | Supply MFA token non-interactively |
--session-name | Custom role session name |
