Individual skill

return-path-gate

Audits SKILL.md files in plugins/ for return-path gate compliance. Detects fire-and-forget chains where a caller dispatches a downstream skill but does not gate its next step on the callee's verdict. Reports each chain as CLOSED or OPEN and outputs specific fix suggestions. Triggered by "chain audit", "return-path check", "fire-and-forget detection", "chain closure audit", "skill chain compliance".

# return-path-gate — Skill Chain Closure Audit

A skill chain is CLOSED when the callee's verdict folds back into the caller's decision logic. A chain is OPEN (fire-and-forget) when the caller dispatches a downstream skill but proceeds independently of the result.

This skill audits `§Chains` and `§Done When` sections across SKILL.md files to detect OPEN chains and prescribe specific closures.

## Role Separation from harness-doctor

| Dimension | harness-doctor | return-path-gate |
|---|---|---|
| **What it checks** | Structural completeness (files, references, line counts, drift) | Chain closure compliance (caller/callee verdict handoff) |
| **Core question** | "Are the required harness files present and consistent?" | "Does the caller wait for the callee's verdict?" |
| **Failure mode detected** | Missing CLAUDE.md, broken refs, complexity drift | Fire-and-forget chains, unverified CONDITIONAL_PASS conditions |
| **Output** | L1–L5 structural health report | CLOSED/OPEN chain table with fix prescriptions |
