About this skill

Machine result contract (internal)

Interactive skills remain text-first. A headless driver obtains a compact, validated result at the boundary; it does not add a repeated JSON section to every user-facing skill.

The canonical Turn contract remains here for the executor and review skills that load it.

The executable source of truth is @gtrabanco/agentic-workflow-schema: types, JSON Schemas, renderOutputInstruction(skill), parseTurn(input), and compileWorkflowSnapshot(input). This document states the policy only; do not copy a second schema here.

Output profiles

WORKFLOW_SKILL_PROFILES is the authoritative inventory.

  • workflow-status always returns the strict Envelope v2 sensor result. Its envelope includes the detailed project view under detail.
  • The other driver-invoked skills return SkillOutcome v1 only when the driver appends renderOutputInstruction(skill) to that invocation. It has the small model-owned fields: outcome, next intent/targets, blockers, questions, discoveries, and evidence references.
  • advance (the companion pi package command) is the conductor, not a worker profile: it runs as deterministic code over the sensor envelope and never emits a worker SkillOutcome.
  • Interactive invocations emit their normal human-readable reports; no driver result is required.

Both results are one final fenced json block. The package rejects unknown keys at the routing boundary. Repository facts are never reconstructed from model prose: the driver compiles WorkflowSnapshot v1 from its selected, versioned documents and caller-supplied repository facts.

Driver protocol

  1. Read the profile and append renderOutputInstruction(skill) only for a driven invocation.
  2. Pass the final response to parseTurn({skill, text, context}). Keep the returned source and diagnostics with the run journal.
  3. On an absent, malformed, or invalid machine result, re-invoke the same session once with: Emit only the machine result for the turn above.
  4. Parse the repair reply. A second failure is driver-level FAILED; never retry indefinitely and never turn arbitrary prose into workflow facts.

Compatibility is deliberately narrow: it can repair documented legacy v2 shapes only when the missing value is mechanically knowable. A nonzero issue count without issue identities, an unmatched numeric unit id, or unrelated prose remains invalid and is surfaced to the driver.

Contract evolution

  • Envelope v2 is strict for new drivers. detail is required (usually null) and skill-specific extensions live inside it; design_candidates, for example, is detail.design_candidates, never a root key.
  • workflow-status retains Envelope v2 for existing sensor consumers. parseEnvelope() remains the legacy-compatible package API; new consumers use parseEnvelopeV2Strict() or parseTurn().
  • SkillOutcome v1 and WorkflowSnapshot v1 are separate, versioned JSON Schemas. A breaking change to any published contract is a package major.

Normalized Repository State

Drivers call discover-repository-state before planning and retain the frozen docs/workflow/REPOSITORY_STATE.md reference. WorkflowSnapshot v1 preserves unknowns, provenance, and declared contradictions; a driver routes a contradiction to resolve-repository-state rather than silently replacing it.
