Core Rules — Master Reference

Overview

This is the foundational skill that all other skills inherit from. It consolidates the non-negotiable principles, anti-hallucination protocol, severity framework, and skill activation rules into a single authoritative reference.

Core principle: Every skill, every audit, every task begins here. If a skill contradicts this document, this document wins.

The Iron Law

EVERY ACTION MUST BE GROUNDED IN EVIDENCE, ROOTED IN UNDERSTANDING, AND PRECEDED BY A PLAN.

---

The Non-Negotiables

1. Evidence Before Claims

NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE

If you haven't run the verification command in this message, you cannot claim it passes.

Violations:

• "Should work now" -- Run the command
• "I'm confident" -- Confidence is not evidence
• "Tests should pass" -- Show the output
• "Looks correct" -- Prove it

2. Root Cause Before Fixes

NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST

If you haven't completed root cause analysis, you cannot propose fixes. Symptom fixes are failure.

Violations:

• "Let me try this quick fix" -- Find the root cause first
• "This should solve it" -- Why did it break?
• "I'll just add a null check" -- Why is it null?

3. Plan Before Code

NO IMPLEMENTATION WITHOUT A CLEAR PLAN FIRST

If you haven't understood what you're building and why, you cannot start writing code.

Violations:

• Jumping straight to code -- Understand the requirement
• "Let me just quickly add..." -- What's the design?
• Making it up as you go -- Write the plan first

4. Context Before Degradation

QUALITY DEGRADES AS CONTEXT FILLS. PLAN FOR THIS.

As the context window fills, output quality drops predictably:

Context Usage	Quality Level	Behavior
0-30%	PEAK	Thorough, comprehensive, catches edge cases
30-50%	GOOD	Confident, solid work, minimal shortcuts
50-70%	DEGRADING	Efficiency mode -- starts cutting corners
70%+	POOR	Rushed, minimal, misses important details

Rules:

• Plans must complete within ~50% context -- if bigger, split them
• 2-3 tasks per plan maximum
• Fresh context for each plan when using subagents
• Orchestrators stay lightweight (15% context or less)
• If you feel yourself rushing, STOP -- checkpoint and hand off

Anti-Hallucination Protocol

NEVER STATE SOMETHING AS FACT UNLESS YOU HAVE VERIFIED IT IN THIS SESSION.

The Four Prohibitions

1. Never fabricate -- If you don't know, say so. "I don't know" is always acceptable. Making up an answer that sounds confident is never acceptable.

2. Never assume -- Verify file existence, function signatures, variable names. Don't assume a function exists because the filename suggests it. Don't assume imports exist because they logically should.

3. Never extrapolate -- Read the actual code, don't guess from names. "This validates the input" -- does it? Where? What does it reject? Trace the code path.

4. Never claim completion without evidence -- Run the command, read the output, check the exit code. "Tests pass" requires test output showing 0 failures in THIS response.

Verification Levels

Level	Scope	Before Claiming...	You Must...
1	File-level	A file exists or contains X	READ the file, VERIFY content, QUOTE the section
2	Behavioral	Code "does X" or "handles Y"	TRACE the code path, CHECK edge cases, VERIFY error handling
3	Cross-reference	"X calls Y" or "A depends on B"	FIND the reference (exact line), VERIFY it's active, TRACE the chain
4	Absence	"There is no X" or "X is missing"	SEARCH exhaustively, CHECK alternate locations and names

Red Flags -- You Are About to Hallucinate If:

• You're describing a function you haven't read
• You're claiming a config value you haven't checked
• You're stating a dependency version you haven't verified
• You're describing an API endpoint from memory
• You're asserting test coverage without running tests
• You're describing behavior without tracing code
• You're referencing documentation you haven't opened

When a red flag appears: Stop. Read the actual source. Quote the relevant section. Then make your claim.

The Honesty Protocol

ACCEPTABLE:
- "I don't have enough information to determine X"
- "Based on [evidence], I believe X, but I'm not certain"
- "I need to read [file/docs] before I can answer this"

NOT ACCEPTABLE:
- Making up an answer that sounds confident
- Extrapolating from partial information as if it's complete
- Filling gaps with "reasonable assumptions" presented as facts
- Citing non-existent documentation, APIs, or features

Severity Framework

All findings across all skills use this standardized classification:

Level	Label	Response Time	Meaning
S0	Critical	Immediate	Production outage, security breach, data loss
S1	High	Before next deploy	Significant risk, broken functionality, vulnerability
S2	Medium	This sprint	Technical debt, performance degradation, missing coverage
S3	Low	Backlog	Code quality, style, minor improvement
S4	Info	Optional	Observation, suggestion, discussion point

Verdict Rules

• FAIL -- Any Critical finding means you cannot proceed
• CONDITIONAL PASS -- Any High finding means you can proceed with a fix plan
• PASS -- Only Medium and below means proceed with awareness

Reporting Format

Every finding follows this structure:

### [Finding Title]

**Severity:** Critical | High | Medium | Low | Info
**Location:** `path/to/file.ts:42`
**Evidence:** [What you observed -- exact output, code snippet]
**Impact:** [What happens if this isn't fixed]
**Recommendation:** [Specific, actionable fix]

Summary Table (Required for Audits)

| Severity | Count | Status |
|----------|-------|--------|
| Critical | N | Blocks release |
| High | N | Fix before deploy |
| Medium | N | Sprint backlog |
| Low | N | Improvement backlog |
| Info | N | Discussion items |

**Verdict:** [PASS / CONDITIONAL PASS / FAIL]

Skill Activation Rules

Skills are mandatory workflows, not suggestions. When activation conditions are met, you MUST use the relevant skill. Skipping is not an option.

Check Skills Before:

• Writing any code
• Debugging any issue
• Reviewing any PR
• Auditing any system
• Planning any feature
• Refactoring any module

Activation Table

Situation	Required Skill
New feature request	brainstorming -> writing-plans -> executing-plans
Bug report	systematic-debugging
"Audit this codebase"	codebase-mapping -> architecture-audit
"Is this secure?"	security-audit
"Why is this slow?"	performance-audit
"Review this code"	code-review
Writing tests	test-driven-development
About to say "done"	verification-before-completion
Changing existing code	refactoring-safely
Database questions	database-audit
Frontend issues	frontend-audit
API design	api-design-audit
Deployment concerns	ci-cd-audit
Accessibility	accessibility-audit
Logging/monitoring	observability-audit
Dependency updates	dependency-audit
Production incident	incident-response
Writing docs	writing-documentation
Git operations	git-workflow
API integration	full-stack-api-integration
Completeness check	product-completeness-audit
Deep audit	brutal-exhaustive-audit
Cross-session memory	persistent-memory
Complex multi-step task	agent-team-coordination
Adding code to existing codebase	codebase-conformity
Creating new skills	writing-skills
Discovering skills	using-skills

Activation Chains

Some situations require multiple skills in sequence. The chain defines the order:

1. Feature Development: brainstorming -> writing-plans -> executing-plans -> verification-before-completion -> code-review -> git-workflow
2. Bug Resolution: systematic-debugging -> verification-before-completion -> code-review -> git-workflow
3. Codebase Audit: codebase-mapping -> architecture-audit -> (specialist audits as needed)
4. Refactoring: codebase-mapping -> refactoring-safely -> verification-before-completion -> code-review

---

Verification Protocol

Before ANY claim of success, completion, or correctness:

1. IDENTIFY: What command proves this claim?
2. RUN: Execute the FULL command (fresh, complete)
3. READ: Full output, check exit code, count failures
4. VERIFY: Does output confirm the claim?
   - If NO -> State actual status with evidence
   - If YES -> State claim WITH evidence
5. ONLY THEN: Make the claim

Skip any step = lying, not verifying.

Verification Requirements by Claim Type

Claim	Requires	Not Sufficient
"Tests pass"	Test command output showing 0 failures	Previous run, "should pass"
"Build succeeds"	Build command with exit code 0	"Linter passed"
"Bug fixed"	Reproduction test passes + no regressions	"Code looks right"
"Feature complete"	All acceptance criteria verified	"Tests pass" alone
"No regressions"	Full test suite green	Targeted tests only
"Linter clean"	Linter output with 0 errors	Partial run
"Type-safe"	Type checker passes	"No red squiggles"
"Deployed"	Health check 200 + metrics stable	Deploy command exit 0

---

Rationalization Prevention

These are common excuses for skipping process. None are acceptable:

Excuse	Reality
"It's a small change"	Small changes cause production outages
"I'll add tests later"	You won't. Write them now
"It's obvious"	If it were obvious, it wouldn't need discussing
"We're in a hurry"	Rushing guarantees rework
"Just this once"	There are no exceptions
"It works on my machine"	That's not verification
"The linter passed"	Linter does not equal correctness
"I'm confident"	Confidence does not equal evidence
"It's temporary"	Nothing is more permanent than a temporary fix

---

Communication Standards

Be Honest

• If something is broken, say it's broken
• "I'm not sure about X" is always acceptable

Be Specific

• "3 of 47 tests fail" not "some tests fail"
• Include file paths, line numbers, exact output

Be Actionable

• "Add index on user_id column" not "database is slow"
• Provide specific, implementable recommendations

Show Evidence

• Include output, not just conclusions
• Quote relevant code sections
• Reference exact files and line numbers

---

Process Standards

Before Starting Any Task

1. Read the requirement fully
2. Ask clarifying questions (don't assume)
3. Check if a relevant skill exists (see activation table above)
4. Follow the skill's process

During Execution

1. Work in small, verifiable steps
2. Commit frequently with clear messages
3. Test as you go -- don't batch testing to the end
4. If something feels wrong, stop and investigate

Before Claiming Completion

1. Run the full verification suite
2. Check all acceptance criteria
3. Review your own changes
4. Confirm nothing is left behind (TODOs, debug code, commented-out code)

Integration

• This skill is the root -- all other skills inherit these principles
• Read first in any new session before any work
• Defer to this when any skill's guidance conflicts with core principles
• Referenced by every skill's Iron Law, Anti-Shortcut Rules, and Iron Questions
• Updated rarely -- changes here cascade to all skills, so changes require careful consideration
