AI Assistant Protocol

Core rules that apply to all files and all roles.

Iron Laws

These are absolute rules. No rationalization, no exceptions, no "just this once."

1. NO CLAIMS WITHOUT FRESH EVIDENCE — Never say "done", "fixed", or "passing" without running the command and reading the output in this session. Stale evidence is not evidence.
2. NO FIXES WITHOUT ROOT CAUSE — Never apply a fix without first identifying and confirming the root cause. Guessing is not debugging.
3. NO IMPLEMENTATION WITHOUT PLAN APPROVAL — Never write code for a feature without the user approving the approach first. Wasted code is worse than no code.
4. NO COMMIT WITHOUT PASSING TESTS — Never commit code that has not been verified by running tests, typecheck, and lint. "It should pass" is not passing.
5. NO SCOPE CREEP WITHOUT APPROVAL — Never fix, refactor, or improve code outside the current task scope. Create a todo instead.
6. NO SILENT FAILURES — Never swallow an error, skip a failing step, or move on without reporting what happened. Every failure gets reported.
7. NO ASSUMPTIONS ABOUT CODE — Never assume code behavior from reading alone. Run it, test it, verify it.

Law Composition

When multiple skills are active, their iron laws compose as follows:

1. Protocol iron laws always apply — The 7 laws above are unconditional
2. Workflow-specific laws add to protocol laws — They introduce additional constraints for their domain (e.g., /tdd adds "no production code without a failing test")
3. Workflow laws never override protocol laws — If a workflow law conflicts with a protocol law, the protocol law wins
4. Priority order resolves all remaining conflicts — See Priority Order below

Execution Protocol

1. Read completely — Review referenced instructions before starting
2. Follow exactly — Execute steps precisely as written
3. Ask when unclear — Request clarification before proceeding
4. Document deviations — Only deviate with explicit user approval
5. Verify completion — Confirm all steps completed before marking done

Verification Before Completion

Universal rule: No claims without fresh evidence.

Before claiming any task is complete, you MUST run actual commands and see actual output.

What Does NOT Count as Verification

• Previous test runs (even from minutes ago)
• Partial checks ("lint passed, so it probably works")
• Confidence or assumptions ("this should work")
• Memory of earlier output
• Another agent's report (verify independently)

Verification Workflows

Code change verification:

1. Run typecheck → read output
2. Run lint → read output
3. Run scoped tests → read output
4. Confirm all three pass before claiming done

Bug fix verification:

1. Regression test passes → read output
2. Related tests pass → read output
3. Original bug no longer reproduces → confirm

Refactor verification:

1. All existing tests pass (no behavior change) → read output
2. Typecheck passes → read output
3. No new warnings introduced → confirm

Build verification:

1. Clean build succeeds → read output
2. No warnings in build output → confirm
3. Build artifacts exist → verify

Red Flag Language — NEVER Use When Reporting Results

• "should work", "probably fine", "seems correct"
• "I already checked", "this was verified earlier"
• Premature "Done!", "All set!", "Perfect!" before verification
• "the tests should still pass"
• "this is a minor change so it's fine"
• "I don't think we need to check..."
• "let me just quickly..."
• "this is similar to what we did before so..."
• "I'm confident this works"
• "based on my understanding..."
• Any claim of success without showing command output

Common Rationalizations

The Excuse	The Rebuttal
"This is too simple to need tests"	Simple code becomes complex. Untested code breaks silently. Test it.
"The test just ran, no need to re-run"	Stale results are not evidence. You may have changed something since. Run it again.
"This should work because the logic is straightforward"	"Should work" is not verification. Run the command. Read the output.
"I already read this file, I know what it does"	Context degrades. If you're making changes, re-verify the current state.
"It's just a small change, no need for approval"	Small changes cause big bugs. Follow the gate.
"The user probably means yes"	"Probably" is not explicit approval. Ask clearly.
"I can fix this while I'm here"	Out of scope. Create a todo instead. Scope creep compounds.
"Tests are passing so it must be correct"	Tests verify what they test, not overall correctness. Think about what's NOT tested.
"I'll add tests later"	Later never comes. Write tests with the code or before the code.
"This error is unrelated, I can ignore it"	Investigate first. "Unrelated" errors are often symptoms of the same root cause.

Priority Order (When Instructions Conflict)

1. User's explicit request (highest)
2. This protocol
3. Domain-specific guidelines
4. Workflow-specific instructions
5. General best practices (lowest)

Code Quality Standards

General Principles

1. Prefer editing to creating — Edit existing files over creating new ones
2. Follow existing patterns — Match surrounding code style
3. No premature optimization — Clear code first, optimize when needed
4. Test as you go — Run tests for changed components only
5. Security by default — See Security Standards below
6. Scope awareness — Confirm with user at 6+ file changes; require refactor workflow at 16+

Comments Policy

Write comments for:

• Non-obvious behavior explanations
• Complex algorithm explanations
• Workaround justifications with ticket references

Avoid comments for:

• Obvious code that repeats function/variable names

Logging

• Use project's logger (not console.log)
• Log levels: debug, info, warn, error

Security Standards

These rules apply to all code written or modified. Violations are blockers — fix before proceeding.

Never Write

Pattern	Risk	Alternative
eval(userInput) / new Function(userInput)	Code injection	Avoid dynamic code execution; use a safe parser
element.innerHTML = userInput	XSS	Use textContent or framework escaping ({variable} in JSX)
dangerouslySetInnerHTML={{__html: userInput}}	XSS	Sanitize with DOMPurify first, or avoid entirely
`SELECT * FROM x WHERE id = '${id}'`	SQL injection	Use parameterized queries or ORM
exec(userInput) / execSync(userInput)	Command injection	Use execFile() with explicit argument array
const KEY = 'sk_live_abc123'	Secret exposure	Use process.env.KEY with validation
rejectUnauthorized: false	TLS bypass	Fix certificates; never disable in production
--no-verify on git hooks	Bypasses safety	Fix the hook failure instead

Always Do

• Validate input at system boundaries — API routes, form handlers, webhook receivers
• Use parameterized queries — ORM calls or tagged template literals for raw SQL
• Hash passwords with bcrypt (12+ rounds) or argon2
• Set security headers — Use helmet or equivalent
• Check auth and authz on every protected route and operation
• Scan for secrets before committing — grep for API keys, tokens, credentials

When to Flag for Review

If any of these appear in changed code, flag them for the user even if they look safe:

• child_process usage (any variant)
• Raw SQL queries (even parameterized — verify correctness)
• Redirect URLs constructed from user input
• File system operations with user-controlled paths
• Cryptographic operations (verify algorithm choice)

Testing Requirements

Scoped Test Execution

Always scope tests to changed components only. Avoid full test suite unless explicitly requested.

# Commands below use npm as default — adapt to project package manager (see Project Commands)
npm run test -- ComponentName
npm run test -- "src/components/"

Test Plan Requirement

All test files MUST include a test plan comment in Gherkin format:

/**
 * Test Plan: ComponentName
 *
 * Scenario: Brief description
 *   Given [initial state]
 *   When [action]
 *   Then [expected outcome]
 */

Project Commands

Skills reference commands generically (e.g., "run the project's test command"). Resolve the actual command as follows:

1. If .ai-project/project/commands.md exists, use the commands defined there
2. Otherwise, detect from lock files:
   • pnpm-lock.yaml → use pnpm
   • yarn.lock → use yarn
   • bun.lockb → use bun
   • Default → npm
3. Standard command mapping:

Task	Generic Reference	npm Example
Type check	project typecheck command	npm run typecheck
Lint	project lint command	npm run lint
Test (scoped)	project test command	npm run test -- [pattern]
Test (full)	project test command	npm run test
Build	project build command	npm run build
Dev server	project dev command	npm run dev
Format	project format command	npm run format

Command examples throughout skills use npm run as the default. Adapt to the detected package manager.

Documentation Policy

For documentation standards (when to comment, JSDoc, README guidelines), see documentation-guidelines.

File Creation Rules

Create freely: Config files, stories, specs, tests, source code, entries in project todos and file lists.

Require user approval: README.md, documentation files, API documentation, architecture diagrams, CHANGELOG.md.

Communication Style

For communication templates and response formatting, see communication-guidelines. For voice, tone, and interaction boundary rules, see interaction-boundaries.

Task Management

Use task tracking for complex tasks (3+ steps). Skip for trivial tasks.

• Mark task in_progress BEFORE starting (one at a time)
• Mark task completed IMMEDIATELY after finishing
• Update in real-time, don't batch completions

Scope Management

Scope	Files	Action
Small	1-5	Proceed directly
Medium	6-15	Confirm with user, suggest /refactor if structural
Large	16+	Must use refactor workflow

Gate Enforcement

Workflows with approval gates require explicit approval before proceeding.

Valid approval: yes, y, approved, proceed, lgtm, looks good, go ahead Invalid (NOT approval): Silence, questions, "I see", "okay", "hmm"

Individual skills may accept domain-specific terms (e.g., commit in the commit workflow). These supplement — never replace — the list above.

Skill Coordination

Self-Contained Workflows

These skills include their own validation and commit phases. Do not chain additional validation or commit skills after them:

Skill	Includes
/implement	explore + plan + code + self-review + test + validate + commit
/finish	test + validate + review + commit
/debug	reproduce + analyze + fix + verify + commit
/refactor	context + analysis + plan + execute + validate + commit
/hotfix	triage + fix + verify + commit
/migrate	assess + plan + generate + review + apply + validate + commit
/release	prepare + version + validate + tag
/deps	audit + plan + update + validate + commit

Do NOT chain: /finish after /implement, /validate after /finish, /commit after /debug. The enclosing workflow already performs these steps.

Composable Building Blocks

These skills perform a single concern and are designed to be called independently or referenced within larger workflows:

Skill	Purpose
/validate	Run quality checks only
/test-coverage	Add missing tests only
/commit	Stage and commit only
/review	Read-only code analysis
/explore	Read-only investigation
/plan	Design approach only
/track-files	Track file batches for large-scale work

Decision Tree

• Know what to do, 1-2 files? → Edit directly
• Know what to do, 3-5 files? → /implement
• Structural change, 6+ files? → /refactor
• Approach unclear? → /plan, then /implement or /tdd
• Bug with unknown cause? → /debug
• Production emergency? → /hotfix
• Code written, need tests? → /test-coverage
• Want tests first? → /tdd
• End of work session? → /finish (only if work was not done via a self-contained workflow)

Token Optimization

1. Search before reading — find relevant files first
2. Read selectively — only files you need to modify
3. Avoid re-reading — don't re-read files already in context
4. Plan before executing — think through approach first
