cut
Skill0 starsChanged 37 days agoMITView on GitHub
Deletion gate before planning. Inspired by Elon Musk's 5-step process (Step 2: delete any part or process you can). Starts from zero, forces every requirement to earn its way back in by proving it's essential to test the core assumption. Logs every run to a scorecard so you can see your own over-building patterns over time. Use when you have a build idea and want to pressure-test it before planning. Triggers: "/cut", "cut this down", "delete before we build", "sharpen this", "what can we kill", "run it through the filter". Do NOT use for bug fixes, maintenance, or operational work — the filter is for new features and ideas, not routine work.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
12 rules. 0 are common, 12 are distinctive, and 0 are very specific to this project.
0
Common
Most of the 4 edited versions we read keep these.
12
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.

If you cannot identify one, the request is not ready — say so and STOP with verdict STOP.

After the log writes successfully, tell the user:

Do not start building. Stop here.
“Common” is measured: kept by at least 6 in 10 of the 4 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
/cut — Delete Before You Build
You are a requirements filter. Default to cutting. Anything the founder explicitly asked for stays (mark it [OVERRIDE]) unless he agrees to drop it. Requirements must earn their way back in.
Step A: Get the build idea
If the user passed a build description as arguments, use that as the input.
If arguments are empty or missing, ask ONE question using AskUserQuestion:
"What are you thinking about building? Describe it in plain English — the feature, the idea, whatever's in your head. I'll run it through the filter."
Options:
- A) (text input via "Other")
- B) Cancel — I'm not ready yet
If they cancel, stop immediately. Do not log anything.
Step B: Run the filter
Apply this prompt to the build idea. Default to cutting. Anything the founder explicitly asked for stays (mark it [OVERRIDE]) unless he agrees to drop it.
Precondition — State the core assumption
What is the single assumption this build is testing? One sentence. If you cannot identify one, the request is not ready — say so and STOP with verdict STOP.
Step 1 — Delete everything
Start with zero requirements. Every single one is cut. No exceptions yet.
Step 2 — Add back only what's essential
For each deleted requirement, ask one question: "If we shipped v1 WITHOUT this, would we fail to test the core assumption?"
- Clear YES → add it back
- Anything else (nice to have, makes it better, we'll need it eventually) → stays cut
Smart-sounding sources produce the most dangerous assumptions. "Best practice," "industry standard," and "we should probably" all stay cut.
Step 3 — Founder override
If the founder explicitly demanded something (literally said "I want this" — not inferred, not assumed), mark it [OVERRIDE]. It survives, but it's tagged. Overrides show the founder their own fingerprints on the scope. Aesthetics and personal-tool preferences belong here.
Step 4 — Simplify
Take what survived (essentials + overrides). Size it to test the core assumption and nothing else. If two approaches exist, choose the one that can be reversed.
Output
- Core assumption: [one sentence]
- Delete list: [everything cut and stays cut, one line each with reason]
- Add-back list: [what earned its way in, with the specific reason it's essential]
- Override list: [if any, marked [OVERRIDE]]
- v1 spec: [what to actually build]
- Verdict:
- GO — spec is tight, assumption is testable, hand the v1 to
/spec(in openly) or/plan-ceo-reviewelsewhere - REVISE — [one sentence on what needs to change]
- STOP — [one sentence on why this isn't ready, plus one suggestion for sharpening]
- GO — spec is tight, assumption is testable, hand the v1 to
Do not plan. Do not suggest implementation details. Do not ask clarifying questions. Stop after the output above.
Step C: Log the run to the scorecard
After producing the output above, append one JSON line to the scorecard log via the shared logger. Every value is a command-line argument taken from the filter output you just produced — numbers unquoted, lists as JSON, strings quoted:
eval "$(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)" 2>/dev/null || true
SLUG="${SLUG:-$(basename "$PWD" | tr -cd 'a-zA-Z0-9._-')}"
SLUG="${SLUG:-unknown}"
LOGGER="$HOME/Projects/claude-config/bin/log-scorecard"
[ -x "$LOGGER" ] && "$LOGGER" --log "$HOME/.gstack/projects/$SLUG/cut-log.jsonl" \
"project=$SLUG" \
'core_assumption=<one-sentence assumption from the output>' \
'requirements_proposed=<int: total requirements brought in>' \
'requirements_deleted=<int: final delete-list count>' \
'deleted=["<short label per cut item>"]' \
'survived=["<short label per add-back>"]' \
'overrides=[]' \
'verdict=<GO | REVISE | STOP>' \
'notes=' \
|| echo "logger missing — skipped scorecard entry"Replace every <...> with the real value before running. overrides is the
list of [OVERRIDE] labels or []; notes stays empty unless something is
worth flagging for future review.
Step D: Hand off
After the log writes successfully, tell the user:
- The v1 spec (already shown above, but call it out as "here's what to build")
- The verdict with the next action:
- GO → "Hand the v1 to
/spec(in openly) or/plan-ceo-reviewelsewhere." - REVISE → "Adjust the request per the note above, then re-run
/cut." - STOP → "This isn't ready yet. Try [suggestion from filter output]."
- GO → "Hand the v1 to
- "Logged to the scorecard. /coach reads it weekly (Step 1g) as the over-build baseline."
Do not plan. Do not suggest implementation details beyond the v1 spec. Do not start building. Stop here.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
