Use when designing and implementing a new software feature from scratch — triggers the Fable-plan → implement → review pipeline.
Use when declaring or checking the token budget / model tier for this session. Triggers on: "set effort", "how much budget do we have", "low on tokens", "use opus", "use sonnet", "constrained this week", or any explicit model-tier selection. Can also be called mid-session to downgrade tier when tokens run low.
Generate an implementation-ready Product Requirements Document for a feature: self-clarify the open questions (no user interview), then write a structured PRD — goals, one-session tasks with verifiable acceptance criteria, numbered functional requirements, non-goals — saved to /tasks/prd-<feature-name>.md, ready for the `tasks` skill to convert into an executable plan. Use when the user asks "create a prd", "write a prd for X", "plan this feature", "spec out X", "requirements for X", or after running `build-options` (its Phase 4 hands the winning option here).
Convert a PRD markdown file (typically `/tasks/prd-<feature>.md` from the `prd` skill) into `prd.json` — an ordered, dependency-sorted execution plan where every acceptance criterion is a boolean check an agent can pass or fail without a human. Use when the user asks "convert prd", "create tasks", "prd to json", "generate tasks from prd", or after running `/prd` at the end of the `/market-validation → /build-options → /prd → /tasks` chain.
Map and maintain the founder-skills <-> PlatAtlas integration surface: the fable-org-audit endpoint map (with its known drift against the live worker), the market-validation market-map sink (nodes.json + flows.json into workflow-atlas, shape-valid but load-untested), adoption guidance for PlatAtlas rail agent seats, and the documented-not-executed mirror plan into workflow-atlas's own plugin convention. Use when a maintainer says "how does founder-skills connect to PlatAtlas", "is the org-audit endpoint map still current", "prove the market-map sink", "load the market map into PlatAtlas", "can the rail agents use these skills", "mirror founder-skills into workflow-atlas", or "what drifted on the PlatAtlas side".
Decide WHAT to build after a market is validated: generate divergent build options, score them with an independent judge panel into a weighted decision matrix, adversarially stress-test the top, recommend one (with kill criteria), render a Tufte decision matrix, and hand the winner to the `prd` skill. Use when the user asks "what should I build", "what are my build options", "which option should we build", "decide what to build", or after running `market-validation`.
Use when you need to verify that a customer organization on your platform is healthy and getting full value — a live integration audit that probes real API signals across eight dimensions, not a code review. Triggers on: "audit this org", "is <org> healthy", "health-check the integration", "why does this org feel off", or a scheduled pre-demo / weekly org check.
Validate whether there is a real market for a product idea, end to end: scope questions → a multi-angle web-research workflow with mandatory live-URL verification → a cited evidence pack → a Tufte HTML deck + PDF + PPTX → a build/integrate brief and an emitted market-map graph. Use when the user asks "is there a market for X", "validate demand for", "prove the market for", "should I build X", "market research / competitor + willingness-to-pay evidence for X", or wants a fundable evidence pack.
