avoid-feature-creep

avoid-feature-creep is a skill for Codex from J-StaR-Films-Studios/VibeCode-Protocol-Suite. It costs 33 tokens per session (2,472 once invoked), scanned A, a copy of avoid-feature-creep, ISC.

A planning and review guide that keeps software work limited to the requested scope. Feature creep is the gradual addition of extra work that was not part of the original plan.

In plain words
What is it for?
Use it when planning features, defining a minimum viable product, reviewing scope, or building an initial version.
Why use it?
It helps prevent over-engineering, unnecessary abstractions, and features that do not belong in the current release.

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

avoid-feature-creep 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.

Avoid Feature Creep for Agents

Stop building features nobody needs. This skill helps you ship products that solve real problems without drowning in unnecessary complexity.

Feature creep kills products. It delays launches, burns budgets, exhausts teams, and creates software nobody wants to use. The most successful products do fewer things well.

The Core Problem

Feature creep is the gradual accumulation of features beyond what your product needs to deliver value. It happens slowly, then all at once.

Warning signs you're in trouble:

  • Release scope keeps growing without clear user value
  • You're copying competitor features without validating need
  • Stakeholders keep adding "just one more thing"
  • The codebase is getting harder to maintain
  • Users complain the product is confusing or bloated
  • You haven't shipped in months

What it costs:

  • Development time on features 80% of users never touch
  • Increased bug surface area
  • Team burnout and context switching
  • Delayed time-to-market
  • Technical debt that compounds
  • User confusion and abandonment

Decision Framework

Before adding ANY feature, run through this checklist:

1. VALIDATE THE PROBLEM
   □ Does this solve a real, validated user pain point?
   □ Have we talked to actual users about this need?
   □ What evidence supports building this?

2. CHECK ALIGNMENT
   □ Does this support the core product vision?
   □ Would this delay our current release?
   □ What are we NOT building if we build this?

3. MEASURE IMPACT
   □ How will we know if this feature succeeds?
   □ What KPIs will change?
   □ Can we quantify the value (time saved, revenue, retention)?

4. ASSESS COMPLEXITY
   □ What's the true cost (build + test + maintain + document)?
   □ Does this add dependencies or technical debt?
   □ Can we ship a simpler version first?

5. FINAL GUT CHECK
   □ Would we delay launch by a month for this feature?
   □ Is this a differentiator or just table stakes?
   □ Would removing this harm the core experience?

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.
