Agent Harness
Turns a domain folder of skills into a bounded agentic loop: compile a goal into a task plan, execute with the domain's tools, verify every task, retry within a budget.
Before & after
Same prompt, same agent — the only difference is the skill.
That sounds like a job for an automated workflow. You'll want to break it down into discrete tasks, then figure out how to verify each one. The challenge is you need domain-specific tools for each task, and some tasks will fail and need retry logic. You might also want to set spending or attempt caps so it doesn't loop forever. Really though, it depends on what your domain is and what tools you have available—I'd need to understand your setup better to give you a concrete plan.
GOAL: Drive marketing funnel task set to verified close TASK PLAN → Research content gaps in product category → Write 3 blog posts addressing gaps → Upload posts to CMS and schedule → Generate social teasers for each post → Verify publishing and engagement setup DOMAIN TOOLING Marketing domain includes: content research, writing, CMS integration, social scheduling, analytics verification. VERIFICATION GATES (machine-run checks) • Blog post length >=800 words • All posts scheduled within 1 week • Social teasers reference original posts • CMS entries have alt text • Analytics filters match business objectives BUDGET & RETRY Max 12 task executions. Retry failed tasks 2x with revised approach. Escalate research gaps to human if both retries fail. Never close until all verifications pass or explicitly waived by user.

Agent Harness
Turn any domain folder of skills into a bounded agentic loop: compile a goal into a verifiable task plan, execute tasks with the domain's own tools, verify every task with machine-run checks, retry with caps, escalate to a human when budgets exhaust, and refuse to close until everything is verified or explicitly waived. Use when you want an agent or subagent to pick up a goal and drive it to a verified close across one of this repo's 18 domains ('run this goal through the engineering harness', 'set up an agentic loop for marketing work', 'make the finance domain self-verifying'). NOT for authoring Claude Code Workflow-tool .js scripts (workflow-builder), N-agent tournaments on one task (agenthub), single-file metric optimization (autoresearch-agent), or discovering published loop recipes (loop-library).
