- /accessibility-gate
Use as a pass/fail gate on any diff with a user-facing surface — by code-reviewer during review, by qa-engineer during the test pass, and by any IC before claiming a UI ticket done. This is the gate the plan called for instead of an accessibility specialist role. Triggers
Open skill - /agent-isolation
Use before spawning any agent that writes files, and by every developer/fixer agent as its first and last action. Gives each agent its own git worktree, forbids blanket staging, and requires confirming a mutation actually landed. Triggers from /app-build, /app-audit,
Open skill - /architecture-builder
Use to produce the technical architecture doc and engineering principles for a mobile app. Used primarily by the CTO agent. Triggers on "design the architecture", "pick the stack", or as part of /app-plan.
Open skill - /board-doctor
Use to validate docs/31-board.md before spawning any agent, and to verify a developer's "DONE" claim before moving a row to review. Triggers as step 0 of /app-build and /app-run, from /app-status, and any time the board looks inconsistent. Catches tickets the sprint loop cannot
Open skill - /brownfield-onboarding
Use when pointing the team at an EXISTING, already-built app instead of a blank project — detects the stack, reverse-engineers the as-built architecture, and classifies remediation work as safe-to-auto-fix vs risky-needs-approval. Triggered by /app-onboard, /app-audit, and by
Open skill - /business-model
Use when deciding or revisiting how the product makes money — pricing, tiers, trial shape, ad load, unit economics — by ceo when setting the model, by cpo when a scope decision turns on revenue, and by product-researcher when investigating willingness to pay. A pricing analysis
