About this skill

Generate Harness DSL

Create a standalone Harness as Code v0.3 document and prove the execution contract with the package compiler and resolver.

Workflow

  1. Identify the host, the capabilities it must actually expose, and the real control owner. Use session for one host session. Use state-machine or program only when a selected adapter explicitly implements that mode.
  2. Read the DSL contract. Start from the minimal example; open the standard example when callable tools are required.
  3. Generate one self-contained document unless the user requests a fragment. Include language 0.3, every referenced declaration, a concrete runtime, and a named deployment. Standard tools may remain implicit.
  4. Run scripts/validate.mjs. Fix every compiler or resolution error and rerun. A compile-only state machine is not an executable Qoder or Pi deployment.
  5. Return the DSL or saved file plus the harness id, deployment id, runtime, resolution status, and any execution boundary the selected adapter cannot satisfy.

Authoring Rules

  • State only falsifiable requirements. Do not add permission, setting, degradation, binding, input/output-name, or runtime-execution syntax; v0.3 intentionally has none.
  • Match the requirement verb to its capability: use skill, require tool, or connect mcp.
  • Only the standard tool ids in the contract may be undeclared. Every custom tool declares a stable contract id that the adapter exposure must match.
  • Qoder and Pi descriptors run session workflows only. A session workflow names exactly the one agent role declared by each harness that uses it.
  • State-machine outcomes are typed on agents. Every route emitter, outcome, destination, entry, and stop must exist, and every agent must be reachable.
  • A program <language> <entry> workflow resolves only when the adapter lists the same language in programmaticLanguages.
  • Keep credentials out of source. Prefer env.VARIABLE for MCP endpoints, but remember that declaring an endpoint does not connect it; the adapter must do that.
  • Do not invoke host SDKs, install integrations, or claim native enforcement while generating or validating DSL.

Validate

From this skill directory, run:

node scripts/validate.mjs /path/to/workflow.harness [harness-id ...]

The command prints JSON and exits non-zero when compilation or any selected named deployment fails resolution. A successful exit is required before calling generated DSL executable.

When editing this skill, build the package first so dist/ reflects the current compiler:

npm run harness:build
