GitHub maintainer queues, issue discovery, triage, and creation, pull-request creation and stacking, review authoring and feedback, CI check-fix workflows using gh CLI. Use for read or write work on GitHub issues, PRs, stacks, reviews, or checks.
Default lifecycle for routine bug fixes, features, refactors, migrations, dependency updates, configuration, scripts, and code. Routes investigation through handoff. Excludes answer-only, diagnosis-only, review-only, architecture-only, large, cross-cutting, and unattended work.
Select concrete model seats, fallbacks, and quota circuits when provider diversity, a named model, or a route retry matters. Caller owns lifecycle, phase boundaries, and final judgment.

Sixteen principles, one index. Match the situation to a row, then read that reference in full before applying it. Each reference is short.
| Principle | Apply when |
|---|---|
| laziness-protocol | Refactoring, sizing a diff, or tempted to add abstractions, layers, or signal threading. |
| model-the-domain | Stateful logic, repeated shape assumptions, or branching spread across files. |
| separate-before-serializing-shared-state | Multiple writers contend for one slot, cache, or merged config value. |
| boundary-discipline | Validation, error handling, parsing, framework adapters, or external data. |
| make-operations-idempotent | Activation, migration, install, retry, or hook paths that can run twice. |
| type-system-discipline | Types or signatures in a statically typed language. |
| subtract-before-you-add | Sequencing an addition, refactor, or rewrite. Remove dead weight first. |
| migrate-callers-then-delete-legacy-apis | Replacing an API or call path. Migrate callers and delete the old path together. |
| minimize-reader-load | Code that requires too many layers or too much hidden state to understand. |
| fix-root-causes | Debugging. Trace each symptom to its root cause; reproduce first. |
| sequence-verifiable-units | Multi-step work and commit or PR stacking. Verify each unit before the next. |
| verified-slice | Implementing one reviewable, reversible unit with evidence and commit authority. |
| prove-it-works | After completing a task, before declaring done. Check the real artifact. |
| guard-the-context-window | Context fills up: large outputs, long files, repeated reads, fan-out planning. |
| encode-lessons-in-structure | The same instruction gets written a second time, or a correction recurs. |
| build-the-lever | Non-trivial edits, migrations, analyses, or checks. Build the rerunnable tool. |
Cite a principle only when it changed a concrete choice. A citation with no decision behind it means the reference was skipped.
Workflow skills reference principles by short name, for example "the prove-it-works principle". Resolve those names against this index.
Seven principles adapt pstack guidance. Upstream terms are in LICENSE.
