# Verify Before Plan A premise is anything the orchestrator's plan asserts about the world without having looked: "there are 41 SKILL.md files that need editing," "the deprecated endpoint still has callers," "build is green on main," "the agent must rewrite the manifest." Before a wave of parallel subagents fans out against that premise, **verify it with a small read-only probe**. A wrong premise propagates to every brief in the wave and wastes an entire wave's worth of work — restarting is the only honest salvage. ## When to Use This Skill | Use this skill when... | Skip when... | |---|---| | About to dispatch ≥2 parallel agents whose briefs cite a number, state, or path | Single-agent delegation — verify inline | | The premise was carried in from an earlier message and not re-checked this session | The premise was produced by a tool call earlier in this same session | | The user's report describes a symptom; the plan cites a cause | Waves entirely independent of repo state (e.g. brainstorming) | | The plan assumes a tool/library/agent does X based on its name or docs | The behaviour is covered by a passing test the wave will re-run | | The plan inherits a premise from another agent's return contract | The return contract already cites file:line evidence for the premise | This skill sits **before** `parallel-agent-dispatch` in the dispatch sequence. `parallel-agent-dispatch` covers the contract; this skill covers the assumption the contract is built on. ## The Verificat
