Evaluate whether to add a new runtime or development dependency to a public open-source project before adding it. Use whenever a new package is proposed. Weighs standard-library alternatives, cost, transitive impact, maintenance, license, supply-chain risk, and low-resource effect, then decides add, do not add, or defer. Does not install anything.
Implement the smallest complete change that satisfies the current acceptance criteria for a public open-source project. Use when writing or editing code after a plan or a clear acceptance criterion exists. Avoids speculative abstraction, unrelated changes, obvious comments, and unverified validation claims. Keeps the project runnable after the increment.
Audit an implementation for unnecessary artifacts, test manipulation, hardcoded shortcuts, fake success, bypassed product paths, and unsupported completion claims
Prepare a new public open-source repository, or convert a small existing directory into a clean publishable starting point. Use for an empty or nearly empty repo, a first local commit, or a first remote push. Do not use for routine feature work or releasing an established project. Never commits, creates a remote, or pushes unless explicitly requested.
Produce an execution plan before writing substantial code for a public open-source project. Use when starting or extending a feature to define the narrowest end-to-end slice, validation per step, trust boundaries, deployment path, and public-repository risks. Keeps the project runnable after every step. Does not write implementation code.
Review the current diff or a specified set of files as public open-source code before publishing or merging. Use to check code quality, public-repository safety (secrets and private data), documentation trustworthiness, provenance, onboarding, and maintainability. Reports grouped findings; does not fix them unless asked.
Prepare a public open-source project for release and deploy it to a detected target. Use at a release or submission boundary to verify setup, docs, secrets, tests, lint, build, and licenses, then follow the target-specific deployment path. Runs expensive checks sequentially. Never publishes, tags, commits, pushes, or deploys without explicit user intent.
Diagnose and repair a failing test, build, or runtime error in a public open-source project using the narrowest reproduction and validation. Use when something is broken and the cause is not yet known. Classifies the failure, isolates a reproduction, applies the smallest fix, and confirms with a targeted check. Does not add features.
