check-kickoff-traps (hook)

Status: shipped-beta · Ships to: plugin · Fires at: PostToolUse with matcher Edit|Write|MultiEdit on .claude/orchestrator-prompts/<wave>/kickoff.md. Gate: exit 2 + stderr on violation.

What it is

The kickoff T-enumeration floor (ai-laziness-traps §3, obligation #2): when a kickoff ENGAGES the traps rule (mentions ai-laziness-traps), the hook asserts the mechanical floor — at least 3 DISTINCT canonical T-numbers enumerated in the kickoff.

How it works

Fewer than 3 named traps is the #trap-catalogue-blanket-reference anti-pattern: citing the rule as decoration while naming no traps. Principle 12 (CI) checks citation PRESENCE only — this hook adds the COUNT floor and reaches edit-time, the earliest (and for kickoffs the only) gate: kickoffs are authored and dispatched before any pre-push/CI channel runs on their content. Whether the named traps are the RIGHT ones stays judgment — review-time, not gated. Exit 2 on violation is the PostToolUse channel the model receives; ZCode gets JSON additionalContext (exit 2 swallowed as HookRunFailed). Without jq the skip is graceful-but-LOUD.

Fail mode: exit 2 + stderr (CC) / JSON emit (ZCode) when an engaged kickoff names <3 distinct traps; silent exit 0 otherwise (including kickoffs that never engage the rule).

Satellites & companions

USES .claude/rules/ai-laziness-traps.md §3 as the spec; complements principle 12's citation-presence CI test; shares the plugin/hooks/lib/hook-emit.sh prelude; twin of .claude/hooks/check-kickoff-traps.sh (auto-generated).
