spec-workflow-harness

v5.9.0

Autonomous SDD harness for Spec Workflow MCP: the 'continue the sdd process' supervisor, one orchestrator agent per phase, and pinned worker agents. Ships no MCP server; use it with a project that configures spec-workflow in its own .mcp.json.

Included Skills2

sdd-continueskills/sdd-continue/SKILL.md

Continue the spec-driven development (SDD) process for the active spec. A thin supervisor that resolves the spec store and code roots, finds the active spec and its live phase, spawns one phase orchestrator at a time, and runs the retrospective conversation. Use when the user says "continue the sdd process", "continue sdd", "run the sdd loop", "next sdd step", or when this skill is invoked by name.

sdd-document-phaseskills/sdd-document-phase/SKILL.md

Runs one SDD document phase (requirements, design, or tasks) of one spec to agent-side approval. Drafts v1, runs adversarial review and revision rounds with pinned worker agents, rules on standoffs, adjudicates past the v4 cap, approves the final version, prunes superseded approval records, cleans the reviews directory, and reports in the orchestrator contract. Used by the sdd-document-orchestrator agent, not directly from a main session.
