write-agent-goal

Turns a task into a goal contract an autonomous agent can be held to: a verifiable end state, the evidence that proves it, the boundaries the run must respect, and the exits that stop it. Fixes the two failures goal-gated runs actually die of: a run "marked done" on the worker's own word, and a run that can never satisfy its condition because the condition was never checkable.

When NOT to use

• Runtime symptoms — the loop stalls, repeats itself, drifts, or ignores caps → engineer-agent-loop. Diagnose the harness first; the goal text may be fine.
• Ordinary prompt work — rewriting a system/task prompt → optimize-prompt.
• Comparing or benchmarking prompts → evaluate-prompts.
• Human/project goal-setting — OKRs, tickets, roadmap "definition of done" with no autonomous run attached.
• Compound asks ("rewrite the goal AND add harness caps"): write the goal text here, then hand off to engineer-agent-loop for enforcement.
