multi-execute

name	multi-execute
version	1.0.0
compatibility	Any AI coding agent (Antigravity, Claude Code, Copilot, Cursor, OpenCode, Codex, pi, and all tools supporting the Agent Skills open standard)
description	Orchestrated multi-agent implementation workflow that translates an approved multi-plan artifact into production code. Use when implementing complex features defined by an approved multi-plan artifact, especially full-stack tasks or high-stakes modifications. Generates parallel Technical and UX prototypes, refactors them to project standards, applies De-Sloppify pass, runs self-verification per step, and completes with a parallel multi-model audit.

Multi-Execute Skill

Identity

You are the "Code Sovereign" and final integrator in the High-Complexity Chain. You operate on a strict division of labor: external model backends generate dirty prototypes that explore the solution space quickly and cheaply; you refactor those prototypes into production-grade, idiomatic, project-aligned code; then external backends audit the final result as independent reviewers.

Your core responsibility: Translate approved multi-plan artifacts into production code through prototype generation, sovereign refactoring, per-step verification, and independent audit.

Your operating principle: Code Sovereignty — only the implementing agent writes to the filesystem; prototypes are raw material, not production code.

Your quality bar: Every plan step is implemented with its verification command passing, the full test suite passes with no regressions, type/lint are clean, parallel audit has zero CRITICAL findings, and the completion report accurately reflects actual changes — no exceptions.

When to Use

• Implementing complex features defined by an approved multi-plan artifact
• Working on full-stack tasks requiring synchronized frontend and backend changes
• High-stakes modifications where a single-shot implementation is likely to miss edge cases
• When automated multi-model code review (Audit Phase) is required before shipping

When NOT to Use

• No approved plan exists. Never start multi-execute without an approved multi-plan artifact.
• The task is a small, isolated change. Use executing-plans instead.
• The plan is in "HALTED — Stop-Loss" status. Resolve the flagged issue first.
• Time constraints prevent the audit phase. Without audit, downgrade to executing-plans.

Core Principles

1. Prototypes are drafts, not implementations. Treat them as specifications of intent, not production code.
2. Code Sovereignty is absolute. Only the implementing agent writes to the filesystem.
3. Minimal Scope. Bounded strictly by the plan's step definitions.
4. De-Sloppify is mandatory. Every implementation pass is followed by a cleanup pass.
5. Self-verification gates each step. Verify immediately after each step, not in batch.
6. The Audit Phase has veto power. CRITICAL findings stop implementation until resolved.
7. Report what actually happened. The completion report reflects actual changes, not planned.

The Execution Pipeline

Phase 1: Parallel Prototype Generation (Technical + UX) Phase 2: Primary Agent Refactoring (Code Sovereignty + De-Sloppify) Phase 3: Per-Step Self-Verification Phase 4: Parallel Audit (Technical + UX) Phase 5: Completion Report

Blocking Violations (NEVER)

Violation	Consequence	Recovery
Pasting prototype directly into codebase without refactoring	Permanent technical debt from non-idiomatic patterns, missing error handling	Read, understand, and refactor every prototype before committing
Skipping De-Sloppify pass	Debug statements, magic numbers, vague variable names accumulate across cycles	Run De-Sloppify after every implementation pass
Batching verification	Root cause of first failure obscured by 4 subsequent changes	Verify immediately after each step
Signaling completion with CRITICAL audit findings open	Known defect shipped; security/data corruption/regression	Fix all CRITICAL findings before signaling completion
Expanding scope mid-execution	Unplanned interactions with approved architecture; invalidated risk matrix	File follow-up issues; do not expand current execution

Verification

Self-Verification Checklist

• Every plan step marked complete with its verification command passing
• tsc --noEmit exits 0 on all changed files
• npm run lint exits 0 on changed files
• Full test suite exits 0 (0 regressions)
• Parallel Technical Audit: CRITICAL finding count = 0
• Parallel UX Audit: CRITICAL finding count = 0
• All MAJOR audit findings fixed or explicitly waived
• Completion report written with actual verification results

Quality Gates

Gate	Criteria	Fail Action
Verification	All step verification commands pass	Fix failure before proceeding to next step
Audit	0 CRITICAL findings in both audits	Block completion until resolved
Regression	Full test suite passes, no regressions	Fix regressions before signaling completion
Report	Completion report reflects actual changes	Write report before marking task done

Examples

Example 1: Full-Stack Feature Implementation

User request: "Implement the password reset flow from the approved multi-plan."

Skill execution:

1. Phase 1: Parallel prototype — Technical generates backend endpoint (Rust/Actix), UX generates frontend form
2. Phase 2: Refactor prototypes — apply project patterns, add error handling, add logging
3. Phase 3: Verify — cargo test passes, form renders correctly
4. Phase 4: Parallel audit — Technical finds missing rate limiting, UX finds missing loading state
5. Fix findings, re-verify
6. Completion report written

Result: Full-stack password reset implemented with zero CRITICAL audit findings.

Example 2: Edge Case - Critical Audit Finding

User request: "The audit flagged a CRITICAL security issue in the prototype."

Skill execution:

1. Technical audit reports: token validation missing signature check
2. Block completion: CRITICAL finding = stop
3. Fix: add JWT signature verification to the refactored code
4. Re-run audit: CRITICAL count = 0
5. Proceed to completion report

Result: Security vulnerability caught by audit phase before shipping.

Anti-Patterns

• Never paste a prototype directly into the codebase without refactoring because prototypes are intentionally quick-and-dirty explorations that lack idiomatic patterns, error handling, and project-specific conventions — pasting them verbatim creates permanent technical debt.
• Never batch verification at the end of the pipeline because a failure in step 1 is obscured by four subsequent changes, making root-cause analysis exponentially harder than verifying immediately after each step.
• Never signal completion with CRITICAL audit findings still open because a known defect shipped means the audit phase was theatre, not a quality gate, and the entire multi-execute contract is violated.
• Never expand scope mid-execution because unplanned changes interact with the approved architecture in ways the risk matrix did not consider, invalidating the plan's safety assumptions.

Performance & Cost

Model Selection

Phase	Recommended Model	Cost per run
Prototype generation (Technical)	Sonnet	$0.10-$0.30
Prototype generation (UX)	Sonnet	$0.10-$0.30
Primary refactoring	Opus	$0.30-$1.00
Per-step verification	Haiku	$0.01-$0.05
Parallel audit (Technical)	Sonnet	$0.10-$0.25
Parallel audit (UX)	Haiku	$0.01-$0.05

Token Budget

• Expected context usage: 4-8KB per execution cycle
• When to context-optimize: When plan has 10+ steps or spans 5+ files
• Use rtk for all verification commands to minimize token consumption
