Use when specs are approved (phase 4 approved in docs/spp/pipeline-state.md) OR when the user directly asks to turn a spec into an implementation plan outside a running pipeline (e.g. "turn this spec into an implementation plan") - writes implementation plans as bite-sized tasks to docs/spp/05-plans/ for subagent-driven execution
Use after completing a task or major feature, before merging, or when the user asks to review a branch, PR, or work-in-progress diff. Run independent Standards and Spec reviews so clean code cannot hide the wrong behavior and correct behavior cannot hide broken standards.
Diagnose bugs, test failures, build failures, unexpected behavior, and performance regressions before proposing fixes. Build a tight reproduction loop, find the root cause, fix it once, and lock it down with a regression test.
Use when implementing any feature or bugfix, before writing implementation code
Use when starting any conversation - routes each request to a single SPP skill by default, running the full idea-to-deploy pipeline only when the user explicitly asks for "pipeline"
Use when a product is ready to ship, OR when the user directly asks how or where to deploy or to write a deploy runbook - chooses a deploy strategy with the owner in cost-and-consequence terms, then executes it into a repeatable runbook. Self-checks on disk for a fixed release version first — it warns and offers to fix it, it does not block.
Use when the user describes a product idea, OR directly asks to capture or write up a product idea brief - captures an idea brief through a one-question-at-a-time interview. Runnable standalone; if docs/spp/pipeline-state.md is absent it starts a fresh journal, if present it appends.
Use when the idea brief is approved (phase 0 approved in docs/spp/pipeline-state.md) OR when the user directly asks to check an idea for competitors, legal risk, or whether it is worth building, outside a running pipeline (e.g. "check this idea for competitors / legal risk / whether it is worth building") - researches competitors, legal risks, market and feasibility before any scoping, with an explicit right to stop the project
