vibecode-pro-max-kit: Skill for Claude Code

.claude/skills/vc-agent-strategy-compare/SKILL.md

vc-agent-strategy-compare is a skill for Claude Code from withkynam/vibecode-pro-max-kit. It costs 52 tokens per session (4,850 once invoked), scanned A, original, MIT.

A comparison tool for choosing how coding agents should carry out a task. It compares doing work in order, using separate agents, following a workflow, or using an agent team.

In plain words
What is it for?
Use it to choose an approach for a project phase or a task that can be split into several independent parts, called a fan-out task.
Why use it?
It makes the trade-offs between speed, agent count, cost, and execution work easier to see before starting.

About the project

vibecode-pro-max-kit is a set of instructions, agents, skills, hooks, and settings that gives AI coding agents a plan-first software development workflow. It is designed for developers, product owners, and other builders using agents such as Claude Code, Codex, Cursor, Windsurf, or Copilot across different technology stacks. The catalogue entries are the kit's own workflow components.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vc-agent-strategy-compare scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-strategy-compare-output.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 285 lines — stays where its author put it; the contents beside it link to each section on GitHub.

vc-agent-strategy-compare

Output style: Follow process/development-protocols/communication-standards.md — answer-first, plain language, no unexplained jargon, TL;DR on long responses.

Evaluate 4 execution strategies for any RIPER-5 phase or fan-out task. Computes the 7-signal score, shows explicit agent count math, applies cost guards, and outputs a ranked strategy recommendation.

All strategies use the existing vc-system agents and skills. The question is only how they are orchestrated.


Model Selection Policy

Every spawned agent — across ALL four strategies (sequential, parallel subagents, dynamic workflow, agent team) — defaults to sonnet. Spawn opus ONLY when the agent is carrying out real source-code or build execution (writing/editing code, running builds, applying migrations). Planning, research, analysis, validation, review, and synthesis all run on sonnet.

Concrete rules:

  • Default = sonnet for any teammate, parallel subagent, or agent() call in a workflow. State the model explicitly when spawning.
  • opus ONLY for execution work: the agent that actually implements code (the vc-execute-agent leg, or a workflow agent() step whose job is to modify source / run a build). The RIPER-5 phase that runs on opus is EXECUTE; all other phases (RESEARCH, SPEC, INNOVATE, PLAN, VALIDATE, UPDATE PROCESS) run on sonnet.
  • Agent-team members: assign sonnet to reviewers, researchers, validators, and planners; assign opus only to the teammate doing real code execution.
  • Dynamic workflows: pass model: 'sonnet' on agent() calls by default; pass model: 'opus' only on the execution stage that writes code or runs builds.
  • Parallel subagents: fan-out investigation/review subagents are sonnet; only an implementing subagent is opus.

Rationale: opus is reserved for the one place judgment-under-execution materially changes code quality. Everything upstream is sonnet-cheap without quality loss, and this keeps fan-outs (which multiply agent count) on the cost-efficient tier. This mirrors the live agent frontmatter: vc-execute-agent, vc-fast-mode-agent, and vc-quick-fix-agent are opus; every other vc-agent is sonnet.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
