Gemini CLI has been EOLed by Google as of 6/18/26

Condense the injected bootstrap without dropping behavior-shaping content:
replace the graphviz flowchart with prose (1% rule, plan-mode->brainstorm gate,
announce + checklist->todos), fold Instruction-Priority into User Instructions,
and drop the per-platform skill-loading section. Keep the full Red Flags
rationalization table (all 12), the platform tool-mapping pointer (now a
skill-relative path list), skill priority framed as a category (process before
implementation, not just the two named skills), and user-instruction precedence
plus the WHAT/HOW guard.

Snapshot on a local branch for review — NOT final, NOT for dev. Open items:
the dropped "Skill Types" (rigid/flexible) section, and evals for user
preferences overriding skills. Clean Docker evals show the more-aggressive
g-minimal preserves load-bearing triggering across opus/sonnet/haiku/codex/
gemini/kimi; this variant keeps more content.

 # Superpowers Release Notes
 
-## v6.1.1 (2026-07-02)
-
-### Codex
-
-- **Codex no longer re-registers the Claude SessionStart hook.** v6.1.0 removed the Codex hook config and its manifest `hooks` pointer, meaning to stop Codex from installing a SessionStart hook — but with no `hooks` field, Codex fell back to auto-discovering `hooks/hooks.json`, the Claude Code SessionStart hook that the marketplace ships from the repo root, and re-registered it along with its install-time trust prompt. The Codex manifest now declares an explicit empty hooks object (`hooks: {}`), which Codex reads as "no hooks" instead of reaching the auto-discovery fallback. An absent field, `[]`, and an empty inline list all collapse back to the fallback, so the value has to be exactly `{}`.
-- **Removed orphaned Codex session-start dead code.** `hooks/session-start-codex` had no caller once the Codex hook config was deleted, so it and its redundant test cases are gone. The worked shell-hook example in `docs/porting-to-a-new-harness.md` moves from Codex — now native skill discovery with no session-start hook — to Cursor, a live shell-hook harness, and the stale `hooks-codex.json` pointer in `docs/windows/polyglot-hooks.md` is corrected. The Codex plugin category is also fixed to "Developer Tools".
-
-### Packaging
-
-- **New `package-codex-plugin.sh` for building the Codex portal package.** A maintainer script produces a deterministic Codex "portal" archive — `.zip` by default, `tar.gz` on request — that normalizes entry timestamps, preserves executable modes, verifies every packaged skill ships its OpenAI metadata, includes the app and composer icons, and refuses to run against a dirty worktree. The packaged manifest keeps the source `hooks: {}` object so a portal-installed plugin avoids the same SessionStart auto-discovery, and the script can rebuild a byte-identical archive from a saved metadata source. Covered by a new test suite.
-
-## v6.1.0 (2026-06-30)
-
-### Lower Per-Session Token Cost
-
-The `using-superpowers` bootstrap is injected into every session, so its size is paid for constantly. This release trims it and the per-harness references it points to, without dropping behavior-shaping content.
-
-- **Compressed the `using-superpowers` bootstrap.** Replaced the graphviz skill-flow diagram with the prose it encoded, folded the standalone Instruction-Priority section into User Instructions, dropped the per-platform "How to Access Skills" walkthrough, and trimmed the Platform Adaptation pointer to the harnesses that still ship a reference file. The full Red Flags rationalization table and the user-instruction precedence rules are unchanged.
-- **Pruned the per-harness tool-mapping references.** The verbose action-to-tool tables restated guidance modern agents already follow. Each reference file is trimmed to the harness-specific notes that still carry weight — subagent dispatch, task tracking, instructions-file paths — and `claude-code-tools.md` and `copilot-tools.md`, which had nothing harness-specific left, are deleted.
-
-### Codex
-
-- **Codex can install from the marketplace.** Codex marketplace sources expect a `.agents/plugins/marketplace.json` at the marketplace root; the repo only shipped the Claude marketplace file, so Codex could name the marketplace but found no installable plugin entries. A repo-local Codex marketplace manifest now points at the same repository root, so the plugin is installable from Codex.
-- **Codex no longer ships a SessionStart hook.** Codex reliably triggers skills on its own, and the bootstrap hook made the UX worse rather than better. The Codex hook config (`hooks-codex.json`) and its manifest registration are removed.
-
-### Harness Support
-
-- **Gemini CLI support removed.** Google EOLed the Gemini CLI on 2026-06-18; the extension can no longer be installed or updated. Gemini is gone from the install docs, the subagent-capable platform lists, and the eval-harness description, and its tool-mapping reference is deleted.

+# Testing Anti-Patterns
+
+**Load this reference when:** writing or changing tests, adding mocks, or tempted to add test-only methods to production code.
+
+## Overview
+
+Tests must verify real behavior, not mock behavior. Mocks are a means to isolate, not the thing being tested.
+
+**Core principle:** Test what the code does, not what the mocks do.
+
+**Following strict TDD prevents these anti-patterns.**
+
+## The Iron Laws
+
+```
+1. NEVER test mock behavior
+2. NEVER add test-only methods to production classes
+3. NEVER mock without understanding dependencies
+```
+
+## Anti-Pattern 1: Testing Mock Behavior
+
+**The violation:**
+```typescript
+// ❌ BAD: Testing that the mock exists
+test('renders sidebar', () => {
+  render(<Page />);
+  expect(screen.getByTestId('sidebar-mock')).toBeInTheDocument();
+});
+```
+
+**Why this is wrong:**
+- You're verifying the mock works, not that the component works
+- Test passes when mock is present, fails when it's not
+- Tells you nothing about real behavior
+
+**your human partner's correction:** "Are we testing the behavior of a mock?"
+
+**The fix:**
+```typescript
+// ✅ GOOD: Test real component or don't mock it
+test('renders sidebar', () => {
+  render(<Page />);  // Don't mock sidebar
+  expect(screen.getByRole('navigation')).toBeInTheDocument();
+});
+
+// OR if sidebar must be mocked for isolation:
+// Don't assert on the mock - test Page's behavior with sidebar present
+```
+
+### Gate Function
+
+```
+BEFORE asserting on any mock element:
+  Ask: "Am I testing real component behavior or just mock existence?"
+
+  IF testing mock existence:
+    STOP - Delete the assertion or unmock the component
+
+  Test real behavior instead
+```
+
+## Anti-Pattern 2: Test-Only Methods in Production
+
+**The violation:**
+```typescript
+// ❌ BAD: destroy() only used in tests
+class Session {
+  async destroy() {  // Looks like production API!
+    await this._workspaceManager?.destroyWorkspace(this.id);
+    // ... cleanup
+  }
+}
+
+// In tests
+afterEach(() => session.destroy());
+```
+
+**Why this is wrong:**
+- Production class polluted with test-only code
+- Dangerous if accidentally called in production
+- Violates YAGNI and separation of concerns
+- Confuses object lifecycle with entity lifecycle
+
+**The fix:**
+```typescript
+// ✅ GOOD: Test utilities handle test cleanup
+// Session has no destroy() - it's stateless in production
+
+// In test-utils/
+export async function cleanupSession(session: Session) {
+  const workspace = session.getWorkspaceInfo();
+  if (workspace) {
+    await workspaceManager.destroyWorkspace(workspace.id);
+  }
+}
+
+// In tests
+afterEach(() => cleanupSession(session));
+```
+
+### Gate Function
+
+```
+BEFORE adding any method to production class:
+  Ask: "Is this only used by tests?"
+
+  IF yes:
+    STOP - Don't add it
+    Put it in test utilities instead
+
+  Ask: "Does this class own this resource's lifecycle?"
+
+  IF no:
+    STOP - Wrong class for this method
+```
+
+## Anti-Pattern 3: Mocking Without Understanding
+
+**The violation:**
+```typescript
+// ❌ BAD: Mock breaks test logic
+test('detects duplicate server', () => {
+  // Mock prevents config write that test depends on!
+  vi.mock('ToolCatalog', () => ({
+    discoverAndCacheTools: vi.fn().mockResolvedValue(undefined)
+  }));
+
+  await addServer(config);
+  await addServer(config);  // Should throw - but won't!
+});
+```
+
+**Why this is wrong:**
+- Mocked method had side effect test depended on (writing config)
+- Over-mocking to "be safe" breaks actual behavior
+- Test passes for wrong reason or fails mysteriously
+
+**The fix:**
+```typescript
+// ✅ GOOD: Mock at correct level
+test('detects duplicate server', () => {
+  // Mock the slow part, preserve behavior test needs
+  vi.mock('MCPServerManager'); // Just mock slow server startup
+
+  await addServer(config);  // Config written
+  await addServer(config);  // Duplicate detected ✓
+});
+```
+
+### Gate Function
+
+```
+BEFORE mocking any method:
+  STOP - Don't mock yet
+
+  1. Ask: "What side effects does the real method have?"
+  2. Ask: "Does this test depend on any of those side effects?"
+  3. Ask: "Do I fully understand what this test needs?"
+
+  IF depends on side effects:
+    Mock at lower level (the actual slow/external operation)
+    OR use test doubles that preserve necessary behavior
+    NOT the high-level method the test depends on
+
+  IF unsure what test depends on:
+    Run test with real implementation FIRST
+    Observe what actually needs to happen
+    THEN add minimal mocking at the right level
+
+  Red flags:
+    - "I'll mock this to be safe"
+    - "This might be slow, better mock it"
+    - Mocking without understanding the dependency chain
+```
+
+## Anti-Pattern 4: Incomplete Mocks
+
+**The violation:**
+```typescript
+// ❌ BAD: Partial mock - only fields you think you need
+const mockResponse = {
+  status: 'success',
+  data: { userId: '123', name: 'Alice' }
+  // Missing: metadata that downstream code uses
+};
+
+// Later: breaks when code accesses response.metadata.requestId
+```
+
+**Why this is wrong:**
+- **Partial mocks hide structural assumptions** - You only mocked fields you know about
+- **Downstream code may depend on fields you didn't include** - Silent failures
+- **Tests pass but integration fails** - Mock incomplete, real API complete
+- **False confidence** - Test proves nothing about real behavior
+
+**The Iron Rule:** Mock the COMPLETE data structure as it exists in reality, not just fields your immediate test uses.
+
+**The fix:**
+```typescript
+// ✅ GOOD: Mirror real API completeness
+const mockResponse = {
+  status: 'success',
+  data: { userId: '123', name: 'Alice' },
+  metadata: { requestId: 'req-789', timestamp: 1234567890 }
+  // All fields real API returns
+};
+```
+
+### Gate Function
+
+```
+BEFORE creating mock responses:
+  Check: "What fields does the real API response contain?"
+
+  Actions:
+    1. Examine actual API response from docs/examples
+    2. Include ALL fields system might consume downstream
+    3. Verify mock matches real response schema completely
+
+  Critical:
+    If you're creating a mock, you must understand the ENTIRE structure
+    Partial mocks fail silently when code depends on omitted fields
+
+  If uncertain: Include all documented fields
+```
+
+## Anti-Pattern 5: Integration Tests as Afterthought
+
+**The violation:**
+```
+✅ Implementation complete
+❌ No tests written
+"Ready for testing"
+```
+
+**Why this is wrong:**
+- Testing is part of implementation, not optional follow-up
+- TDD would have caught this
+- Can't claim complete without tests
+
+**The fix:**
+```
+TDD cycle:
+1. Write failing test
+2. Implement to pass
+3. Refactor
+4. THEN claim complete
+```
+
+## When Mocks Become Too Complex
+
+**Warning signs:**
+- Mock setup longer than test logic
+- Mocking everything to make test pass
+- Mocks missing methods real components have
+- Test breaks when mock changes
+
+**your human partner's question:** "Do we need to be using a mock here?"
+
+**Consider:** Integration tests with real components often simpler than complex mocks
+
+## TDD Prevents These Anti-Patterns
+
+**Why TDD helps:**
+1. **Write test first** → Forces you to think about what you're actually testing
+2. **Watch it fail** → Confirms test tests real behavior, not mocks
+3. **Minimal implementation** → No test-only methods creep in
+4. **Real dependencies** → You see what the test actually needs before mocking
+
+**If you're testing mock behavior, you violated TDD** - you added mocks without watching test fail against real code first.
+
+## Quick Reference
+
+| Anti-Pattern | Fix |
+|--------------|-----|
+| Assert on mock elements | Test real component or unmock it |
+| Test-only methods in production | Move to test utilities |
+| Mock without understanding | Understand dependencies first, mock minimally |
+| Incomplete mocks | Mirror real API completely |
+| Tests as afterthought | TDD - tests first |
+| Over-complex mocks | Consider integration tests |
+
+## Red Flags
+
+- Assertion checks for `*-mock` test IDs
+- Methods only called in test files
+- Mock setup is >50% of test
+- Test fails when you remove mock
+- Can't explain why mock is needed
+- Mocking "just to be safe"
+
+## The Bottom Line
+
+**Mocks are tools to isolate, not things to test.**
+
+If TDD reveals you're testing mock behavior, you've gone wrong.
+
+Fix: Test real behavior or question why you're mocking at all.

-# Writing Good Tests
-
-**Load this reference when:** writing or changing tests, adding mocks, or
-adding cleanup/helper methods for tests.
-
-## Overview
-
-A test exists to catch a specific break. Two principles govern everything
-here:
-
-```
-1. Every test names the break it catches
-2. Every test exercises the real thing
-```
-
-Strict TDD produces both naturally: a test written first and watched
-failing against real code has already proven it can fail, and only earns
-a mock when the real dependency proves slow or external.
-
-## Principle 1: Name the Break
-
-Before writing the test body, answer: **what production change should
-make this test fail — and is that change a bug or a decision?** A test
-earns its place by catching a wrong branch, missing side effect, wrong
-argument, boundary case, or broken contract.
-
-**Derive expectations independently.** Use literals and hand-checked
-fixtures; table-driven tests with literal `want` values are the preferred
-shape. An expectation computed by the code under test — or its helpers —
-passes no matter what that code does:
-
-```typescript
-// ❌ Mirror assertion: the same builder computes both sides — always true
-const expected = buildSearchQuery({ tag: 'urgent' });
-expect(buildSearchQuery({ tag: 'urgent' })).toBe(expected);
-
-// ✅ Hand-derived literal
-expect(buildSearchQuery({ tag: 'urgent' })).toBe('tag:"urgent"');
-```
-
-**No change detectors.** If only intentional decisions can fail a test —
-a constant's value, exact message wording, private structure — it fires
-on redesign and sleeps through bugs. Test the behavior that depends on
-the decision: not `expect(MAX_RETRIES).toBe(5)` but "a failing call is
-retried 5 times and the 6th attempt never happens."
-
-**Behavior, not text.** Asserting that a script, skill, or config
-contains an exact line proves only that the source is the source. Run
-scripts against controlled inputs and assert outputs, side effects, or
-exit codes. Documents that instruct agents are tested by the consuming
-agent's behavior (superpowers:writing-skills); prose for humans earns no
-test at all.
-
-**Your code, not the framework.** Test the contract your code makes at
-its boundaries — the route you register, the query you emit, the payload
-you produce. Upstream mechanics are their maintainers' tests to write
-(the classic: asserting your router invokes a registered handler — that
-is the framework's test, not yours). When upstream behavior genuinely
-surprised you, write one narrow characterization test naming the
-assumption. The same boundary applies inside your code: constructors,
-getters, constants, and trivial forwarding earn tests only when they
-validate, normalize, default, derive, enforce, or cause side effects —
-otherwise assert the first consumer-visible result that depends on them.
-
-### Gate Function
-
-```
-BEFORE writing the test body:
-  Name the production change that would make this test fail.
-
-  Cannot name one            → redesign around an observable behavior
-  "The source text changed"  → run the artifact and assert its effects
-  Only intentional decisions → change detector; test the behavior
-                               that depends on the decision
-
-  Confirm the expected value is derived without the code under test.
-  IF it reuses the code's logic or helpers:
-    Replace it with a literal or hand-checked fixture
-```
-
-## Principle 2: Exercise the Real Thing
-
-**The mock earns no assertions.** A mock assertion passes when the mock
-is present and fails when it is absent — it says nothing about the
-component. Assert the real component's behavior; if the mock is what you
-are checking, unmock it or delete the assertion.
-
-```typescript
-// ✅ Real behavior
-expect(screen.getByRole('navigation')).toBeInTheDocument();
-
-// ❌ Mock existence
-expect(screen.getByTestId('sidebar-mock')).toBeInTheDocument();
-```
-
-**your human partner's correction:** "Are we testing the behavior of a
-mock?"
-
-**Mock at the right level.** Learn every side effect of the real method
-before replacing it; mock the slow or external operation and keep what
-the test depends on real. When unsure, run the test against the real
-implementation first and observe what actually needs to happen.
-
-```typescript
-// ❌ The mock swallows the config write that duplicate detection reads
-vi.mock('ToolCatalog', () => ({
-  discoverAndCacheTools: vi.fn().mockResolvedValue(undefined)
-}));
-
-// ✅ Mock only the slow server startup; the config write stays real
-vi.mock('MCPServerManager');
-```
-
-**Make doubles specific.** When arguments, call counts, or ordering are
-part of the contract, assert them — a fake that accepts anything verifies
-nothing. Give each branch (success, error, malformed) its own fixture or
-spy, so the wrong branch cannot satisfy the expectation.
-
-**Mirror real data completely.** Mock the complete structure as it exists
-in reality — all documented fields — not just the ones your test reads.
-Partial mocks fail silently when downstream code reads an omitted field:
-the test passes while integration breaks.
-
-**Production classes carry production methods only.** Cleanup that only
-tests need lives in test utilities, never as a `destroy()` on the
-production class. Ask: is this method called only from tests? Does this
-class own this resource's lifecycle? Wrong answers → test utility.
-
-**Prefer real components over complex mocks.** When mock setup outgrows
-the test logic, mocks miss methods the real components have, or tests
-break when the mock changes, switch to an integration test with real
-components. **your human partner's question:** "Do we need to be using a
-mock here?"
-
-### Gate Function
-
-```
-BEFORE adding a mock or test helper:
-  List the real method's side effects; keep the ones the test
-  depends on real — mock the slow/external level below them.
-
-  Mock responses mirror the complete real structure.
-
-  A method only tests call lives in test utilities, not production.
-
-  About to assert on the mock itself?
-    Unmock it or delete the assertion.
-```
-
-## Tests Ship With the Implementation
-
-The TDD cycle — failing test, minimal implementation, refactor — is what
-"complete" means. Ship the tests the behavior needs and only those:
-trivial code and human prose earn none, and a test written to satisfy
-process costs maintenance forever.
-
-## The Mutation Check
-
-Before finishing, mentally mutate the production code; at least one test
-should fail for each realistic mutation:
-
-- Wrong constant or argument
-- Wrong branch handler
-- Missing state change or side effect
-- Empty or default return
-- Missing validation for zero, empty, nil, unauthorized, or malformed input
-
-A mutation nothing catches marks the behavior as unprotected — or the
-test as tautological.
-
-## Quick Reference
-
-| When you... | Do |
-|-------------|-----|
-| Write any test | Name the break it catches — a bug, not a decision |
-| Build an expected value | Derive it by hand; never with the code under test |
-| Test a script or document | Run it / pressure-test its consumer; never grep its text |
-| Reach for a dependency test | Test your boundary contract, not their documented mechanics |
-| Want to assert on a mocked element | Test the real component, or unmock it |
-| Are about to mock a method | Learn its side effects; mock the slow/external level |
-| Build a mock response | Mirror the real structure completely |
-| Need cleanup only tests use | Put it in test utilities |
-| Watch mock setup balloon | Switch to an integration test with real components |
-| Finish a test file | Run the mutation check |
-
-## Warning Signs
-
-- Setup and assertion share the same object, guaranteeing equality
-- The test can fail only through a panic, crash, or missing selector
-- The test fails on every intentional change, never on accidental breakage
-- Expected values are hidden behind loops, builders, or helpers
-- The test greps source text, or asserts a removed symbol stays removed
-- The test would still matter if only the framework remained
-- The test exists for coverage, checking no side effect or outcome
-- An assertion checks a `*-mock` test ID, or fails if you remove the mock
-- A method is called only from test files
-- Mock setup is more than half the test, or you can't explain why the mock is needed
-- Mocking "just to be safe"
