vibe-iteration-review

vibe-iteration-review is a skill for Claude Code from mracal/vibe-engineering. It costs 34 tokens per session (521 once invoked), scanned A, a copy of vibe-iteration-review, MIT.

An end-of-iteration review that grades completed development work, measures results, and compares progress with earlier iterations. An iteration is a defined work period, such as a sprint or milestone.

In plain words
What is it for?
Use it after a sprint or milestone to compare planned and delivered work, review tests and known issues, assign a quality grade, and record lessons.
Why use it?
It turns completed work into a clear record of what was delivered, what went wrong, and whether quality is improving. This helps teams choose practical changes for the next iteration.

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

vibe-iteration-review 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 10d ago.

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.

What it actually says

vibe-iteration-review

What gets measured gets improved. Review every iteration.

When to Use This Skill

  • End of a development sprint or iteration
  • After completing a milestone
  • Before starting the next iteration (retrospective)
  • When the user asks "how did we do?"

When NOT to Use This Skill

  • Mid-iteration (too early, incomplete data)
  • After single small tasks
  • When there's no defined iteration boundary

Steps

  1. Gather data:

    • What was planned for this iteration?
    • What was actually delivered?
    • How many commits? Lines changed? Tests added?
    • Coverage delta? Quality metrics?
    • Known issues introduced?
  2. Grade quality (A-F):

    • A: All planned work delivered, tests pass, no known issues, clean code
    • B: Most work delivered, minor issues, good test coverage
    • C: Core work delivered, some gaps, acceptable quality
    • D: Significant gaps, quality issues, needs rework
    • F: Iteration failed, major rework needed
  3. Compare to previous iterations (if available):

    • Is quality trending up or down?
    • Is velocity improving?
    • Are known issues accumulating?
  4. Extract lessons:

    • What went well?
    • What went poorly?
    • What to change next iteration?

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.
