avoid-feature-creepPrevent feature creep when building software, apps, and AI-powered products.
Avoid Feature Creep is an agent skill from udecode/kitcn. Prevent feature creep when building software, apps, and AI-powered products. Use this skill when planning features, reviewing scope, building MVPs, managing backlogs, or when a user says "just one more feature." Helps developers and AI agents stay focused, ship faster, and avoid bloated products.
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including assets (for example `agents/openai.yaml`).
The repository describes itself as: Convex + Better Auth + tRPC + Drizzle + TanStack Query + shadcn. The licence is Apache-2.0.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit c6010f5. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
gitFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Avoid Feature Creep loads about 2.7k tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 1,194 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
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:
What it costs:
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?If you can't answer YES to questions 1-3 with evidence, do not build the feature.
Rule 1: Define and Defend Your MVP
Write down exactly what "done" means before you start. Document what you're NOT building. Reference this constantly.
## MVP Scope Document Template
### Core Problem
[One sentence describing the user problem]
### Success Criteria
[How we know we've solved it]
### In Scope (v1)
- Feature A: [brief description]
- Feature B: [brief description]
### Explicitly Out of Scope
- Feature X: Deferred to v2
- Feature Y: Will not build unless [condition]
- Feature Z: Not our problem to solve
### Non-Negotiables
- Ship by [date]
- Budget: [hours/dollars]
- Core user: [specific persona]Rule 2: Use Version Control for Scope
Treat scope like code. Track changes. Require approval for additions.
# Create a scope document and track it
git add SCOPE.md
git commit -m "Initial MVP scope definition"
# Any scope changes require explicit commits
git commit -m "SCOPE CHANGE: Added feature X - approved by [stakeholder] - impact: +2 weeks"Rule 3: The 48-Hour Rule
When someone requests a new feature, wait 48 hours before adding it to the backlog. Most "urgent" requests feel less urgent after reflection.
Rule 4: Budget-Based Scoping
Every feature has a cost. When something new comes in, something else must go out.
"Yes, we can add that. Which of these three features should we cut to make room?"
Saying no to features is a skill. Here are templates:
To stakeholders:
"That's an interesting idea. Based on our user research, it doesn't solve our core user's top three problems. Let's add it to the v2 consideration list and revisit after we validate the MVP."
To executives:
"I understand the value this could bring. If we add this, we'll delay launch by [X weeks] and deprioritize [Y feature]. Here are the trade-offs - which path should we take?"
To users:
"Thanks for the feedback. We're focused on [core problem] right now. I've logged this for future consideration. Can you tell me more about why this would be valuable?"
To yourself:
"Is this scratching my own itch or solving a real user problem? Would I bet the release date on this?"
To AI agents (Claude, Opus, Codex, Ralph, Cursor):
"Stop. Before we add this feature, answer: Does this solve the core user problem we defined at the start of this session? If not, add it to a DEFERRED.md file and stay focused on the current scope."
When working with AI coding agents:
When building AI-powered products, feature creep has extra risks:
AI Feature Creep Red Flags:
AI Feature Discipline:
Before adding any AI feature, answer:
A messy backlog enables feature creep. Clean it ruthlessly.
Monthly Backlog Audit:
For each item older than 30 days:
1. Has anyone asked about this since it was added?
2. Does it still align with current product vision?
3. If we never built this, would anyone notice?
If the answer to all three is "no" → Delete it.Priority Framework (MoSCoW):
Be honest: Most "Should Haves" are actually "Could Haves" in disguise.
Session Start Check: Before coding with any AI assistant (Claude, Cursor, OpenCode), state:
Mid-Session Check: Every 30-60 minutes, ask your AI: "Are we building the right thing today, or are we adding scope?"
If the answer is "adding scope," stop. Commit what you have. Start fresh.
Session End Check: Before closing an AI coding session:
Daily AI Check: At the end of each day working with AI assistants:
1. Features completed today: [list]
2. Scope additions today: [list]
3. Was each addition validated? [yes/no]
4. Tomorrow's focus: [single item]Sprint Planning Guard Rails:
Stakeholder Management: Create a single source of truth for scope decisions:
## Scope Decision Log
| Date | Request | Source | Decision | Rationale | Trade-off |
|------|---------|--------|----------|-----------|-----------|
| 2025-01-15 | Add export to PDF | PM | Deferred v2 | Not core to MVP | Would delay launch 2 weeks |
| 2025-01-16 | Dark mode | User feedback | Approved | User research shows demand | Removed social sharing |
| 2025-01-17 | Add caching layer | Claude | Deferred | Premature optimization | Stay focused on core feature |
| 2025-01-17 | Refactor to hooks | Cursor | Rejected | Works fine as is | Technical scope creep |Agents as Stakeholders: AI coding agents are now stakeholders in your project. They have opinions. They make suggestions. Treat them like any other stakeholder:
Common agent-driven scope creep patterns:
Each of these might be good ideas. None of them are your current scope unless you decide they are.
If feature creep has already happened:
Step 1: Audit Current Features
Step 2: Categorize
Step 3: Remove or Hide
Step 4: Prevent Recurrence
When reviewing any feature request, ask:
1. "What user problem does this solve?"
2. "What's the smallest version we could ship?"
3. "What are we NOT building to make room for this?"
4. "How will we measure success?"
5. "What happens if we never build this?"If you can't answer these clearly → Do not proceed.
Ship something small that works. Then iterate based on real usage data.
Users don't remember features. They remember whether your product solved their problem.
Every feature you don't build is:
The best products aren't the ones with the most features. They're the ones that do the right things exceptionally well.
"Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away." - Antoine de Saint-Exupéry

Prevent feature creep when building software, apps, and AI-powered products. Avoid Feature Creep is an agent skill from udecode/kitcn. Prevent feature creep when building software, apps, and AI-powered products.
Avoid Feature Creep fits situations like: planning features; reviewing scope; managing backlogs; A user says just one more feature. Helps developers and AI agents stay focused.
Run `npx skills add udecode/kitcn --skill avoid-feature-creep -a claude-code`. Or copy the skill folder (.agents/skills/avoid-feature-creep in udecode/kitcn) into .claude/skills/avoid-feature-creep in your project. Claude Code loads it when a task matches its description.
Run `npx skills add udecode/kitcn --skill avoid-feature-creep -a codex`. Or copy the skill folder (.agents/skills/avoid-feature-creep in udecode/kitcn) into .agents/skills/avoid-feature-creep in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add udecode/kitcn --skill avoid-feature-creep -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/avoid-feature-creep, .gemini/skills/avoid-feature-creep, .github/skills/avoid-feature-creep and .opencode/skills/avoid-feature-creep in your project.
Going by SKILL.md and its folder, Avoid Feature Creep needs the command-line tools its instructions call (git).
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Avoid Feature Creep is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.7k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
