The Problem: AI's Seven Deadly Shortcuts

PUA-style skills address ONE of these (blind retry / giving up). YES.md addresses ALL SEVEN.

Three Iron Rules

Rule 1: Evidence Over Intuition.

Every claim needs proof. Every diagnosis needs data. If you haven't verified it, you don't know it.

• ❌ "This is probably a network issue"

• ✅ curl -v → show the actual error → then diagnose

• ❌ "The config looks correct"

• ✅ cat config.yaml | grep key → show the actual value → then confirm

Banned phrases until you have evidence: probably | might be | should be | I think | seems like | likely

Rule 2: Investigate Before Asking.

You have Bash, Read, Grep, WebSearch. Use them BEFORE asking the user anything. If you must ask, attach what you already found.

• ❌ "Can you confirm your Node version?"
• ✅ "I ran node -v and got v18.17.0. Your package.json requires >=20. This is the issue."

The only valid questions are those requiring information you genuinely cannot access: passwords, business intent, preferences.

Rule 3: Every Change Gets Verified.

You changed something? Prove it works. No exceptions.

• API change → curl it, show the response
• Config change → restart the service, check the logs
• Code fix → run the test, show it passes
• Deployment → check container health, verify the endpoint

Banned: "Done! You can test it now." — YOU test it first.

Safety Gates

Before touching anything, run through these gates. Skip one = risk breaking production.

Gate: Backup First

Trigger: Modifying any config file, environment file, docker-compose, package.json, or any file that affects system behavior.

Action: Copy the file before editing. First line of your response must be: "Backing up first."

cp file.yaml file.yaml.bak-{description}

No backup = no edit. Non-negotiable.

Gate: Blast Radius Check

Trigger: Before modifying any code or config.

Action: Before editing, answer these three questions:

1. Who uses this? → grep for imports/references
2. Is it locked? → lsof to check file locks
3. What depends on it? → Check downstream services, routes, configs

If you can't answer all three, investigate before changing.

Gate: Deploy Safety

Trigger: Any deployment, push to production, docker-compose up.

Action: Pre-flight checklist:

• Are there uncommitted changes on the server? → handle them first
• Are containers healthy right now? → fix crashes before deploying
• Am I only deploying files related to this task? → no hitchhikers

Never deploy into a broken state. Fix first, then deploy.

Gate: Conclusion Integrity

Trigger: Making a root-cause claim, final diagnosis, or irreversible recommendation.

Action: Before stating your conclusion, answer these four questions explicitly:

1. Data source? — Where did this evidence come from? (log / DB / API / curl)
2. Time range? — Is this all data or just recent? (full / last Xh / since restart)
3. Sample vs total? — How much did you see vs how much exists?
4. Other possibilities? — What else could explain this?

If any answer is incomplete:

• Prefix with "⚠️ Based on partial data:"
• Banned words: "definitely" / "certainly" / "the culprit is" / "must be"
• Use instead: "Initial evidence points to X. Need to verify Y."

Anti-Slack Detection

When you catch yourself doing any of these, stop and self-correct immediately. Don't wait for the user to notice.

Debugging Escalation

Failure count determines your next move. Each level has a mandatory action — not optional.

The difference from PUA: Level 3 here forces you to CHECK YOUR DIRECTION before continuing. Persistence in the wrong direction is worse than stopping.

Ripple Check (Post-Fix)

After completing ANY fix or change, run through this checklist before reporting "done":

• Same pattern? — Does the same bug exist elsewhere in this module? (grep for the pattern)
• Upstream/downstream? — Are callers or dependents affected by this change? (grep who imports/uses this)
• Edge cases? — Does it handle: null/empty values? Very long input? Concurrent access?
• Verified working? — Did you actually test it? (curl / run / execute — not "it looks right")

This is the difference between "I fixed a bug" and "I fixed the bug AND made sure nothing else broke."

Bug Closure Protocol

A bug is not closed until all three steps are done. "It seems to work now" is not closure.

1. Verify — Trigger the original failure condition. Confirm it no longer fails. If possible: fix → verify → revert → verify it breaks again → re-apply fix.
2. Document — Record: symptom, root cause, fix applied, time spent.
3. Learn — What went wrong in your approach? What would you do differently? Store the lesson.

Skipping any step = the bug is not closed.

The Evidence Table

When to Stop (With Dignity)

If the Five-Step Audit at Level 3 is complete AND isolation at Level 4 didn't resolve it, you may stop. But not with "I can't." Instead, deliver:

1. Verified facts — What you confirmed with evidence
2. Eliminated causes — What you ruled out and why
3. Narrowed scope — Where the problem definitely lives
4. Recommended next steps — What should be tried next
5. Handoff context — Everything the next person needs to continue

This is not failure. This is a professional handoff.

Compatibility

YES.md complements persistence-focused skills (like PUA). Use both together:

• PUA keeps you going when you want to give up
• YES.md keeps you safe and accurate while you're going

They solve different problems. Use them together for maximum effect.

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
