What it installs

Skills (8)

  • artefact-authoring

    This skill should be used when creating, completing, or reviewing a waterfall lifecycle artefact. Ensures artefacts follow templates, satisfy completeness requirements, and are ready for gate evidence submission with correct closure obligations.

  • gate-checklist

    This skill should be used when preparing for or executing a gate review. Provides binary pass/fail/waived checklists for all 8 gates A-H of the waterfall-lifecycle framework. Use this skill as a pre-flight check before invoking the gate-reviewer agent.

  • handover-management

    This skill should be used when preparing, validating, or executing inter-phase handovers in the waterfall lifecycle. Covers artefact inventory, open items log, risk register transfer, phase transition readiness checklist, and formal handover sign-off.

  • phase-contract-enforcement

    This skill should be used when enforcing compliance with a signed waterfall phase contract — checking mandatory fields, verifying exit criteria completeness before a gate review, and blocking gate requests when contract gaps are found. Distinct from the phase-contract skill (which creates contracts)

  • phase-contract

    This skill should be used when creating or validating a waterfall phase contract — the formal agreement that gates phase entry and exit. Phase contracts in waterfall are binding: no phase starts without approved entry criteria and no gate review without met exit criteria.

  • requirement-authoring

    This skill should be used when authoring, reviewing, or validating requirements in a waterfall lifecycle project — including functional requirements, AI requirements, NFRs, and acceptance criteria. Covers ID assignment, SMART criteria, category assignment, and requirement quality gates.

  • risk-management

    This skill should be used when identifying, assessing, logging, or reviewing risks in a waterfall lifecycle project. Covers all 5 register types: risk, assumption, clarification, dependency, evidence — with waterfall-specific risk categories and formal escalation paths for gate reviews.

  • traceability-mapping

    This skill should be used when creating or maintaining a Requirements Traceability Matrix (RTM), validating traceability coverage, detecting orphaned requirements, and preparing the RTM for Gate B submission.

Slash commands (8)

  • /waterfall-lifecycle:waterfall-artefact-gen

    Generate a waterfall lifecycle artefact from a template, pre-populated with project context.

  • /waterfall-lifecycle:waterfall-baseline-check

    Validate requirements baseline completeness against all Gate B mandatory artefacts and RTM coverage before submitting for gate review.

  • /waterfall-lifecycle:waterfall-gate-review

    Initiate a formal gate review by invoking the gate-reviewer agent with the evidence package for the specified gate.

  • /waterfall-lifecycle:waterfall-handover-prep

    Prepare inter-phase handover package by validating Gate C artefacts, generating handover summary, and assessing phase transition readiness.

  • /waterfall-lifecycle:waterfall-lifecycle-init

    Initialize waterfall-lifecycle framework for a new project. Creates lifecycle-state.json, directory structure, and bootstraps Phase 1.

  • /waterfall-lifecycle:waterfall-lifecycle-status

    Display current waterfall lifecycle state including active phase, gate statuses, and outstanding blockers.

  • /waterfall-lifecycle:waterfall-phase-start

    Start a waterfall lifecycle phase after confirming previous phase gate was passed or waived.

  • /waterfall-lifecycle:waterfall-requirements-review

    Review the requirements set for completeness, testability, and AI/NFR coverage against Phase 2 exit criteria.
