decision-package
Produce the Decision Package — the paid keystone deliverable of a semantic/data consulting engagement's P1 Decision Phase. Use to write the recommendation, the in/out scope, the sequenced (pilot → scale) roadmap, the buy/build/defer decisions, and the ready-to-contract execution brief that hands off to the build/architecture tier. The unit of value is decision-readiness; the artefact sits ABOVE architecture (it justifies and scopes the build before a repo exists). Triggers — "produce a decision package", "write the recommendation / scope / roadmap / buy-build-defer", "decision-readiness deliverable", "execution brief for the build", "scope this engagement", "Semantic Readiness & Direction / Decision Foundation deliverable". This skill PRODUCES the artefact; it does NOT coach the engagement design or hold the free→paid line (that is semantic-consulting-coach — "produce" vs "coach"). Not for free P0 orientation, not for delivery artefacts (an ontology, a mapping), not for code architecture.
estimation
A lightweight fixed-cost scoping / estimation discipline that de-risks fixed-cost bids — a CHECKLIST + METHOD, not a heavy model. Produces a work breakdown plus PERT-weighted effort estimates, uncertainty ranges, assumptions & exclusions, and contingency, feeding the SoW scope boundary. PERT (three-point: optimistic / most-likely / pessimistic) is the default technique; analogous, parametric, and bottom-up are alternatives. Gantt charts / scheduling are rendered in EXTERNAL tools (Smartsheet, MS Project) from the work breakdown — this skill produces the breakdown + estimates, not the chart. It OWNS the estimation/scoping discipline; it DELEGATES the proposal/SoW wrapper to `proposal-writing`, the build breakdown to `epic-planning`, and sequencing to `decision-package`. Triggers — "estimate this engagement", "PERT estimate", "fixed-cost scoping", "work breakdown for estimation", "contingency / uncertainty range". Independently triggerable; also the pricing step of the `proposal-writing` flow.
proposal-writing
Produce the proposal + Statement of Work (SoW) that frames the paid Decision Phase (P1) offer — with an explicit in/out scope boundary, priced as a fixed frame. This is the ENTRY skill of the consulting front-of-funnel: it qualifies the need, frames the Decision Phase offer, prices it (delegating the numbers to `estimation`), and writes the proposal + SoW. It OWNS proposal/SoW production and the scope-boundary discipline; it DELEGATES pricing/effort to `estimation`, executive framing to `executive-communication`, and the P1 deliverable definition to `decision-package`. Triggers — "write a proposal", "draft the SoW / Statement of Work", "scope boundary for this engagement", "fixed-cost proposal", "frame the Decision Phase offer". Not for producing the Decision Package itself (that is `decision-package`), not for free P0 orientation (that is `semantic-consulting-coach`).
