Prompt Contract Bindings

Purpose

Capture the reusable pattern for operationalizing a domain prompt without polluting the generic harness core with project-specific entities, tables, or state machines.

Use when

• A project has an important prompt that must become resumable, inspectable, and operational over many sessions
• The harness core should stay generic while the project keeps local domain schema or workflow details
• A team needs a repeatable bridge from prompt fixture -> schema overlay -> workflow contract -> campaigns/issues -> validation

Canonical Pattern

1. Reusable runtime behavior lives in the harness core and its global skills.
2. Prompt-specific fixtures stay local to the project or workspace.
3. Domain schema overlays stay local to the project or workspace.
4. Prompt-to-workflow bindings stay local to the project or workspace.
5. Mission workflow contracts stay local to the project or workspace.
6. The harness core remains responsible only for generic state such as projects, campaigns, issues, runs, leases, checkpoints, events, artifacts, and memory links.
7. mem0 remains derived support memory only; it never replaces the canonical domain database or lifecycle state.

Recommended File Layout

• .harness/fixtures/<domain>.prompt.original.txt
• .harness/schemas/<domain>.domain.schema.json
• .harness/prompt-workflow-bindings.json
• .harness/mission-workflows/<domain>.workflow.json
• harness-project.json entries pointing at the local prompt, schema, and workflow artifacts
• init.sh, AGENTS.MD, and progress.md updated so future sessions can see and validate the contract immediately

Procedure

1. Save the exact prompt fixture locally.
2. Identify which parts of the prompt are globally reusable behavior vs local domain rules.
3. Keep the reusable behavior in the harness repo or global runtime skills.
4. Create a local domain schema overlay for prompt-required entities.
5. Create a prompt-workflow binding manifest that maps the prompt to schema, campaigns, smoke suites, and operating rules.
6. Create a local mission workflow contract that maps prompt rules to issue stages, checkpoints, and state transitions.
7. Wire the new local artifacts into harness-project.json, init.sh, and local AGENTS.MD.
8. Validate the artifacts on disk and run at least one bootstrap or preview path that proves the bindings do not break the existing lifecycle flow.

Validation Gate

A prompt contract is only operationalized when:

• the prompt fixture exists on disk
• the schema overlay exists on disk
• the binding manifest exists on disk
• the workflow contract exists on disk
• harness-project.json references the new artifacts
• init.sh or equivalent bootstrap detects them successfully
• at least one read-only or preview lifecycle path still succeeds

Anti-patterns

• Adding domain-specific tables directly to agent-harness-core/src/db/sqlite.schema.sql
• Publishing a project-specific prompt as a global skill
• Treating mem0 as canonical domain storage
• Creating a binding manifest without wiring it into project bootstrap and guidance
• Claiming the prompt is global when only the pattern is global and the domain payload is still local

Related Skills

• session-lifecycle — executes the generic queue/lease/checkpoint protocol used by the local workflow
• harness-lifecycle — governs initializer and incremental sessions around the local contract
• planning-tracking — breaks the operationalization work into explicit slices

Version Notes

• 1.0.0 — initial repo-native skill extracted from verified prompt-to-schema/workflow operationalization in combined-auto-runtime while keeping the harness core generic.
