+
+  return `## DX First Principles
+
+These are the laws. Every recommendation traces back to one of these.
+
+1. **Zero friction at T0.** First five minutes decide everything. One click to start. Hello world without reading docs. No credit card. No demo call.
+2. **Incremental steps.** Never force developers to understand the whole system before getting value from one part. Gentle ramp, not cliff.
+3. **Learn by doing.** Playgrounds, sandboxes, copy-paste code that works in context. Reference docs are necessary but never sufficient.
+4. **Decide for me, let me override.** Opinionated defaults are features. Escape hatches are requirements. Strong opinions, loosely held.
+5. **Fight uncertainty.** Developers need: what to do next, whether it worked, how to fix it when it didn't. Every error = problem + cause + fix.
+6. **Show code in context.** Hello world is a lie. Show real auth, real error handling, real deployment. Solve 100% of the problem.
+7. **Speed is a feature.** Iteration speed is everything. Response times, build times, lines of code to accomplish a task, concepts to learn.
+8. **Create magical moments.** What would feel like magic? Stripe's instant API response. Vercel's push-to-deploy. Find yours and make it the first thing developers experience.
+
+## The Seven DX Characteristics
+
+| # | Characteristic | What It Means | Gold Standard |
+|---|---------------|---------------|---------------|
+| 1 | **Usable** | Simple to install, set up, use. Intuitive APIs. Fast feedback. | Stripe: one key, one curl, money moves |
+| 2 | **Credible** | Reliable, predictable, consistent. Clear deprecation. Secure. | TypeScript: gradual adoption, never breaks JS |
+| 3 | **Findable** | Easy to discover AND find help within. Strong community. Good search. | React: every question answered on SO |
+| 4 | **Useful** | Solves real problems. Features match actual use cases. Scales. | Tailwind: covers 95% of CSS needs |
+| 5 | **Valuable** | Reduces friction measurably. Saves time. Worth the dependency. | Next.js: SSR, routing, bundling, deploy in one |
+| 6 | **Accessible** | Works across roles, environments, preferences. CLI + GUI. | VS Code: works for junior to principal |
+| 7 | **Desirable** | Best-in-class tech. Reasonable pricing. Community momentum. | Vercel: devs WANT to use it, not tolerate it |
+
+## Cognitive Patterns — How Great DX Leaders Think
+
+Internalize these; don't enumerate them.
+
+1. **Chef-for-chefs** — Your users build products for a living. The bar is higher because they notice everything.
+2. **First five minutes obsession** — New dev arrives. Clock starts. Can they hello-world without docs, sales, or credit card?
+3. **Error message empathy** — Every error is pain. Does it identify the problem, explain the cause, show the fix, link to docs?
+4. **Escape hatch awareness** — Every default needs an override. No escape hatch = no trust = no adoption at scale.
+5. **Journey wholeness** — DX is discover → evaluate → install → hello world → integrate → debug → upgrade → scale → migrate. Every gap = a lost dev.
+6. **Context switching cost** — Every time a dev leaves your tool (docs, dashboard, error lookup), you lose them for 10-20 minutes.
+7. **Upgrade fear** — Will this break my production app? Clear changelogs, migration guides, codemods, deprecation warnings. Upgrades should be boring.
+8. **SDK completeness** — If devs write their own HTTP wrapper, you failed. If the SDK works in 4 of 5 languages, the fifth community hates you.
+9. **Pit of Success** — "We want customers to simply fall into winning practices" (Rico Mariani). Make the right thing easy, the wrong thing hard.
+10. **Progressive disclosure** — Simple case is production-ready, not a toy. Complex case uses the same API. SwiftUI: \\\`Button("Save") { save() }\\\` → full customization, same API.
+
+## DX Scoring Rubric (0-10 calibration)
+
+| Score | Meaning |
+|-------|---------|
+| 9-10 | Best-in-class. Stripe/Vercel tier. Developers rave about it. |
+| 7-8 | Good. Developers can use it without frustration. Minor gaps. |
+| 5-6 | Acceptable. Works but with friction. Developers tolerate it. |
+| 3-4 | Poor. Developers complain. Adoption suffers. |
+| 1-2 | Broken. Developers abandon after first attempt. |
+| 0 | Not addressed. No thought given to this dimension. |
+
+**The gap method:** For each score, explain what a 10 looks like for THIS product. Then fix toward 10.
+
+## TTHW Benchmarks (Time to Hello World)
+
+| Tier | Time | Adoption Impact |
+|------|------|-----------------|
+| Champion | < 2 min | 3-4x higher adoption |
+| Competitive | 2-5 min | Baseline |
+| Needs Work | 5-10 min | Significant drop-off |
+| Red Flag | > 10 min | 50-70% abandon |

+\`\`\`bash
+gbrain put_page --title "<Person or Company Name>" --tags "entity,person" --content "Stub page. Mentioned in <skill name> output."

+Only extract actual person names and company/organization names. Skip product names, section headings, technical terms, and file paths.
+
+Throttle errors appear as: exit code 1 with stderr containing "throttle", "rate limit", "capacity", or "busy". If GBrain returns a throttle or rate-limit error on any save operation, defer the save and move on. The brain is busy — the content is not lost, just not persisted this run. Any other non-zero exit code should also be treated as a transient failure.
+
+Add backlinks to related brain pages if they exist. If GBrain is not available, skip this step.
+
+After brain operations complete, note in your completion output: how many pages were found in the initial search, how many entities were enriched, and whether any operations were throttled. This helps the user see brain utilization over time.`;

+
+### Tool resolution (read first)
+
+"AskUserQuestion" can resolve to two tools at runtime: the **host MCP variant** (e.g. \`mcp__conductor__AskUserQuestion\` — appears in your tool list when the host registers it) or the **native** Claude Code tool.
+
+**Rule:** if any \`mcp__*__AskUserQuestion\` variant is in your tool list, prefer it. Hosts may disable native AUQ via \`--disallowedTools AskUserQuestion\` (Conductor does, by default) and route through their MCP variant; calling native there silently fails. Same questions/options shape; same decision-brief format applies.
+
+**If no AskUserQuestion variant appears in your tool list, this skill is BLOCKED.** Stop, report \`BLOCKED — AskUserQuestion unavailable\`, and wait for the user. Do not write decisions to the plan file as a substitute, do not emit them as prose and stop, and do not silently auto-decide (only \`/plan-tune\` AUTO_DECIDE opt-ins authorize auto-picking).
+
+### Format
+
+Every AskUserQuestion is a decision brief and must be sent as tool_use, not prose.
+
+\`\`\`
+D<N> — <one-line question title>
+Project/branch/task: <1 short grounding sentence using _BRANCH>
+ELI10: <plain English a 16-year-old could follow, 2-4 sentences, name the stakes>
+Stakes if we pick wrong: <one sentence on what breaks, what user sees, what's lost>
+Recommendation: <choice> because <one-line reason>
+Completeness: A=X/10, B=Y/10   (or: Note: options differ in kind, not coverage — no completeness score)
+Pros / cons:
+A) <option label> (recommended)
+  ✅ <pro — concrete, observable, ≥40 chars>
+  ❌ <con — honest, ≥40 chars>
+B) <option label>
+  ✅ <pro>
+  ❌ <con>
+Net: <one-line synthesis of what you're actually trading off>
+\`\`\`
+
+D-numbering: first question in a skill invocation is \`D1\`; increment yourself. This is a model-level instruction, not a runtime counter.
+
+ELI10 is always present, in plain English, not function names. Recommendation is ALWAYS present. Keep the \`(recommended)\` label; AUTO_DECIDE depends on it.
+
+Completeness: use \`Completeness: N/10\` only when options differ in coverage. 10 = complete, 7 = happy path, 3 = shortcut. If options differ in kind, write: \`Note: options differ in kind, not coverage — no completeness score.\`
+
+Pros / cons: use ✅ and ❌. Minimum 2 pros and 1 con per option when the choice is real; Minimum 40 characters per bullet. Hard-stop escape for one-way/destructive confirmations: \`✅ No cons — this is a hard-stop choice\`.
+
+Neutral posture: \`Recommendation: <default> — this is a taste call, no strong preference either way\`; \`(recommended)\` STAYS on the default option for AUTO_DECIDE.
+
+Effort both-scales: when an option involves effort, label both human-team and CC+gstack time, e.g. \`(human: ~2 days / CC: ~15 min)\`. Makes AI compression visible at decision time.
+
+Net line closes the tradeoff. Per-skill instructions may add stricter rules.
+
+12. **Non-ASCII characters — write directly, never \\u-escape.** When any
+    string field (question, option label, option description) contains
+    Chinese (繁體/簡體), Japanese, Korean, or other non-ASCII text, emit
+    the literal UTF-8 characters in the JSON string. **Never escape them
+    as \`\\uXXXX\`.** Claude Code's tool parameter pipe is UTF-8 native
+    and passes characters through unchanged. Manually escaping requires
+    recalling each codepoint from training, which is unreliable for long
+    CJK strings — the model regularly emits the wrong codepoint (e.g.
+    writes \`\\u3103\` thinking it is 管 U+7BA1, but \`\\u3103\` is
+    actually ㄃, so the user sees \`管理工具\` rendered as \`㄃3用箱\`).
+    The trigger is long, multi-line questions with hundreds of CJK
+    characters: that is exactly when reflexive escaping kicks in and
+    exactly when miscoding is most damaging. Long ≠ escape. Keep
+    characters literal.
+
+    Wrong: \`"question": "請選擇\\uXXXX\\uXXXX\\uXXXX\\uXXXX"\`
+    Right: \`"question": "請選擇管理工具"\`
+
+    Only JSON-mandatory escapes remain allowed: \`\\n\`, \`\\t\`, \`\\"\`, \`\\\\\`.
+
+### Self-check before emitting
+
+Before calling AskUserQuestion, verify:
+- [ ] D<N> header present
+- [ ] ELI10 paragraph present (stakes line too)
+- [ ] Recommendation line present with concrete reason
+- [ ] Completeness scored (coverage) OR kind-note present (kind)
+- [ ] Every option has ≥2 ✅ and ≥1 ❌, each ≥40 chars (or hard-stop escape)
+- [ ] (recommended) label on one option (even for neutral-posture)
+- [ ] Dual-scale effort labels on effort-bearing options (human / CC)
+- [ ] Net line closes the decision
+- [ ] You are calling the tool, not writing prose
+- [ ] Non-ASCII characters (CJK / accents) written directly, NOT \\u-escaped

+
+When tests fail, do NOT immediately stop. First, determine ownership:
+
+### Step T1: Classify each failure
+
+For each failing test:
+
+1. **Get the files changed on this branch:**
+   \`\`\`bash
+   git diff origin/<base>...HEAD --name-only
+   \`\`\`
+
+2. **Classify the failure:**
+   - **In-branch** if: the failing test file itself was modified on this branch, OR the test output references code that was changed on this branch, OR you can trace the failure to a change in the branch diff.
+   - **Likely pre-existing** if: neither the test file nor the code it tests was modified on this branch, AND the failure is unrelated to any branch change you can identify.
+   - **When ambiguous, default to in-branch.** It is safer to stop the developer than to let a broken test ship. Only classify as pre-existing when you are confident.
+
+   This classification is heuristic — use your judgment reading the diff and the test output. You do not have a programmatic dependency graph.
+
+### Step T2: Handle in-branch failures
+
+**STOP.** These are your failures. Show them and do not proceed. The developer must fix their own broken tests before shipping.
+
+### Step T3: Handle pre-existing failures
+
+Check \`REPO_MODE\` from the preamble output.
+
+**If REPO_MODE is \`solo\`:**
+
+Use AskUserQuestion:
+
+> These test failures appear pre-existing (not caused by your branch changes):
+>
+> [list each failure with file:line and brief error description]
+>
+> Since this is a solo repo, you're the only one who will fix these.
+>
+> RECOMMENDATION: Choose A — fix now while the context is fresh. Completeness: 9/10.
+> A) Investigate and fix now (human: ~2-4h / CC: ~15min) — Completeness: 10/10
+> B) Add as P0 TODO — fix after this branch lands — Completeness: 7/10
+> C) Skip — I know about this, ship anyway — Completeness: 3/10
+
+**If REPO_MODE is \`collaborative\` or \`unknown\`:**
+
+Use AskUserQuestion:
+
+> These test failures appear pre-existing (not caused by your branch changes):
+>
+> [list each failure with file:line and brief error description]
+>
+> This is a collaborative repo — these may be someone else's responsibility.
+>
+> RECOMMENDATION: Choose B — assign it to whoever broke it so the right person fixes it. Completeness: 9/10.
+> A) Investigate and fix now anyway — Completeness: 10/10
+> B) Blame + assign GitHub issue to the author — Completeness: 9/10
+> C) Add as P0 TODO — Completeness: 7/10
+> D) Skip — ship anyway — Completeness: 3/10
+
+### Step T4: Execute the chosen action
+
+**If "Investigate and fix now":**
+- Switch to /investigate mindset: root cause first, then minimal fix.
+- Fix the pre-existing failure.
+- Commit the fix separately from the branch's changes: \`git commit -m "fix: pre-existing test failure in <test-file>"\`
+- Continue with the workflow.
+
+**If "Add as P0 TODO":**
+- If \`TODOS.md\` exists, add the entry following the format in \`review/TODOS-format.md\` (or \`.claude/skills/review/TODOS-format.md\`).
+- If \`TODOS.md\` does not exist, create it with the standard header and add the entry.
+- Entry should include: title, the error output, which branch it was noticed on, and priority P0.
+- Continue with the workflow — treat the pre-existing failure as non-blocking.
+
+**If "Blame + assign GitHub issue" (collaborative only):**
+- Find who likely broke it. Check BOTH the test file AND the production code it tests:
+  \`\`\`bash
+  # Who last touched the failing test?
+  git log --format="%an (%ae)" -1 -- <failing-test-file>
+  # Who last touched the production code the test covers? (often the actual breaker)
+  git log --format="%an (%ae)" -1 -- <source-file-under-test>
+  \`\`\`
+  If these are different people, prefer the production code author — they likely introduced the regression.
+- Create an issue assigned to that person (use the platform detected in Step 0):
+  - **If GitHub:**
+    \`\`\`bash
+    gh issue create \\
+      --title "Pre-existing test failure: <test-name>" \\
+      --body "Found failing on branch <current-branch>. Failure is pre-existing.\\n\\n**Error:**\\n\`\`\`\\n<first 10 lines>\\n\`\`\`\\n\\n**Last modified by:** <author>\\n**Noticed by:** gstack /ship on <date>" \\
+      --assignee "<github-username>"

+    \`\`\`bash
+    glab issue create \\
+      -t "Pre-existing test failure: <test-name>" \\
+      -d "Found failing on branch <current-branch>. Failure is pre-existing.\\n\\n**Error:**\\n\`\`\`\\n<first 10 lines>\\n\`\`\`\\n\\n**Last modified by:** <author>\\n**Noticed by:** gstack /ship on <date>" \\
+      -a "<gitlab-username>"
+    \`\`\`
+- If neither CLI is available or \`--assignee\`/\`-a\` fails (user not in org, etc.), create the issue without assignee and note who should look at it in the body.
+- Continue with the workflow.
+

+- Continue with the workflow.

+
+**If runtime detected but no test framework — bootstrap:**
+
+### B2. Research best practices
+
+Use WebSearch to find current best practices for the detected runtime:
+- \`"[runtime] best test framework 2025 2026"\`
+- \`"[framework A] vs [framework B] comparison"\`
+
+If WebSearch is unavailable, use this built-in knowledge table:
+
+| Runtime | Primary recommendation | Alternative |
+|---------|----------------------|-------------|
+| Ruby/Rails | minitest + fixtures + capybara | rspec + factory_bot + shoulda-matchers |
+| Node.js | vitest + @testing-library | jest + @testing-library |
+| Next.js | vitest + @testing-library/react + playwright | jest + cypress |
+| Python | pytest + pytest-cov | unittest |
+| Go | stdlib testing + testify | stdlib only |
+| Rust | cargo test (built-in) + mockall | — |
+| PHP | phpunit + mockery | pest |
+| Elixir | ExUnit (built-in) + ex_machina | — |
+
+### B3. Framework selection
+
+Use AskUserQuestion:
+"I detected this is a [Runtime/Framework] project with no test framework. I researched current best practices. Here are the options:
+A) [Primary] — [rationale]. Includes: [packages]. Supports: unit, integration, smoke, e2e
+B) [Alternative] — [rationale]. Includes: [packages]
+C) Skip — don't set up testing right now
+RECOMMENDATION: Choose A because [reason based on project context]"
+
+If user picks C → write \`.gstack/no-test-bootstrap\`. Tell user: "If you change your mind later, delete \`.gstack/no-test-bootstrap\` and re-run." Continue without tests.
+
+If multiple runtimes detected (monorepo) → ask which runtime to set up first, with option to do both sequentially.
+
+### B4. Install and configure
+
+1. Install the chosen packages (npm/bun/gem/pip/etc.)
+2. Create minimal config file
+3. Create directory structure (test/, spec/, etc.)
+4. Create one example test matching the project's code to verify setup works
+
+If package installation fails → debug once. If still failing → revert with \`git checkout -- package.json package-lock.json\` (or equivalent for the runtime). Warn user and continue without tests.
+
+### B4.5. First real tests
+
+Generate 3-5 real tests for existing code:
+
+1. **Find recently changed files:** \`git log --since=30.days --name-only --format="" | sort | uniq -c | sort -rn | head -10\`
+2. **Prioritize by risk:** Error handlers > business logic with conditionals > API endpoints > pure functions
+3. **For each file:** Write one test that tests real behavior with meaningful assertions. Never \`expect(x).toBeDefined()\` — test what the code DOES.
+4. Run each test. Passes → keep. Fails → fix once. Still fails → delete silently.
+5. Generate at least 1 test, cap at 5.
+
+Never import secrets, API keys, or credentials in test files. Use environment variables or test fixtures.
+
+### B5. Verify
+
+\`\`\`bash
+# Run the full test suite to confirm everything works
+{detected test command}
+\`\`\`
+
+If tests fail → debug once. If still failing → revert all bootstrap changes and warn user.
+
+### B5.5. CI/CD pipeline
+
+\`\`\`bash
+# Check CI provider
+ls -d .github/ 2>/dev/null && echo "CI:github"
+ls .gitlab-ci.yml .circleci/ bitrise.yml 2>/dev/null
+\`\`\`
+
+If \`.github/\` exists (or no CI detected — default to GitHub Actions):
+Create \`.github/workflows/test.yml\` with:
+- \`runs-on: ubuntu-latest\`
+- Appropriate setup action for the runtime (setup-node, setup-ruby, setup-python, etc.)
+- The same test command verified in B5
+- Trigger: push + pull_request
+
+If non-GitHub CI detected → skip CI generation with note: "Detected {provider} — CI pipeline generation supports GitHub Actions only. Add test step to your existing pipeline manually."
+
+### B6. Create TESTING.md
+
+First check: If TESTING.md already exists → read it and update/append rather than overwriting. Never destroy existing content.
+
+Write TESTING.md with:
+- Philosophy: "100% test coverage is the key to great vibe coding. Tests let you move fast, trust your instincts, and ship with confidence — without them, vibe coding is just yolo coding. With tests, it's a superpower."
+- Framework name and version
+- How to run tests (the verified command from B5)
+- Test layers: Unit tests (what, where, when), Integration tests, Smoke tests, E2E tests
+- Conventions: file naming, assertion style, setup/teardown patterns
+
+### B7. Update CLAUDE.md
+
+First check: If CLAUDE.md already has a \`## Testing\` section → skip. Don't duplicate.
+
+Append a \`## Testing\` section:
+- Run command and test directory
+- Reference to TESTING.md
+- Test expectations:
+  - 100% test coverage is the goal — tests make vibe coding safe
+  - When writing new functions, write a corresponding test
+  - When fixing a bug, write a regression test
+  - When adding error handling, write a test that triggers the error
+  - When adding a conditional (if/else, switch), write tests for BOTH paths
+  - Never commit code that makes existing tests fail
+
+### B8. Commit
+
+\`\`\`bash
+git status --porcelain
+\`\`\`
+
+Only commit if there are changes. Stage all bootstrap files (config, test directory, TESTING.md, CLAUDE.md, .github/workflows/test.yml if created):
+\`git commit -m "chore: bootstrap test framework ({framework name})"\`

+
+- **User flows:** What sequence of actions does a user take that touches this code? Map the full journey (e.g., "user clicks 'Pay' → form validates → API call → success/failure screen"). Each step in the journey needs a test.
+- **Interaction edge cases:** What happens when the user does something unexpected?
+  - Double-click/rapid resubmit
+  - Navigate away mid-operation (back button, close tab, click another link)
+  - Submit with stale data (page sat open for 30 minutes, session expired)
+  - Slow connection (API takes 10 seconds — what does the user see?)
+  - Concurrent actions (two tabs, same form)
+- **Error states the user can see:** For every error the code handles, what does the user actually experience?
+  - Is there a clear error message or a silent failure?
+  - Can the user recover (retry, go back, fix input) or are they stuck?
+  - What happens with no network? With a 500 from the API? With invalid data from the server?
+- **Empty/zero/boundary states:** What does the UI show with zero results? With 10,000 results? With a single character input? With maximum-length input?

+- Prioritize error handlers and edge cases first (happy paths are more likely already tested)
+- Read 2-3 existing test files to match conventions exactly
+- Generate unit tests. Mock all external dependencies (DB, API, Redis).
+- For paths marked [→E2E]: generate integration/E2E tests using the project's E2E framework (Playwright, Cypress, Capybara, etc.)
+- For paths marked [→EVAL]: generate eval tests using the project's eval framework, or flag for manual eval if none exists
+- Write tests that exercise the specific uncovered path with real assertions
+- Run each test. Passes → commit as \`test: coverage for {feature}\`
+- Fails → fix once. Still fails → revert, note gap in diagram.
+
+Caps: 30 code paths max, 20 tests generated max (code + user flow combined), 2-min per-test exploration cap.
+
+If no test framework AND user declined bootstrap → diagram only, no generation. Note: "Test generation skipped — no test framework configured."
+
+**Diff is test-only changes:** Skip Step 7 entirely: "No new application code paths to audit."
+
+**6. After-count and coverage summary:**
+
+\`\`\`bash
+# Count test files after generation
+find . -name '*.test.*' -o -name '*.spec.*' -o -name '*_test.*' -o -name '*_spec.*' | grep -v node_modules | wc -l
+\`\`\`
+
+For PR body: \`Tests: {before} → {after} (+{delta} new)\`
+Coverage line: \`Test Coverage Audit: N new code paths. M covered (X%). K tests generated, J committed.\`
+
+**7. Coverage gate:**
+
+Before proceeding, check CLAUDE.md for a \`## Test Coverage\` section with \`Minimum:\` and \`Target:\` fields. If found, use those percentages. Otherwise use defaults: Minimum = 60%, Target = 80%.
+
+Using the coverage percentage from the diagram in substep 4 (the \`COVERAGE: X/Y (Z%)\` line):
+
+- **>= target:** Pass. "Coverage gate: PASS ({X}%)." Continue.
+- **>= minimum, < target:** Use AskUserQuestion:
+  - "AI-assessed coverage is {X}%. {N} code paths are untested. Target is {target}%."
+  - RECOMMENDATION: Choose A because untested code paths are where production bugs hide.
+  - Options:
+    A) Generate more tests for remaining gaps (recommended)
+    B) Ship anyway — I accept the coverage risk
+    C) These paths don't need tests — mark as intentionally uncovered
+  - If A: Loop back to substep 5 (generate tests) targeting the remaining gaps. After second pass, if still below target, present AskUserQuestion again with updated numbers. Maximum 2 generation passes total.
+  - If B: Continue. Include in PR body: "Coverage gate: {X}% — user accepted risk."
+  - If C: Continue. Include in PR body: "Coverage gate: {X}% — {N} paths intentionally uncovered."
+
+- **< minimum:** Use AskUserQuestion:
+  - "AI-assessed coverage is critically low ({X}%). {N} of {M} code paths have no tests. Minimum threshold is {minimum}%."
+  - RECOMMENDATION: Choose A because less than {minimum}% means more code is untested than tested.
+  - Options:
+    A) Generate tests for remaining gaps (recommended)
+    B) Override — ship with low coverage (I understand the risk)
+  - If A: Loop back to substep 5. Maximum 2 passes. If still below minimum after 2 passes, present the override choice again.
+  - If B: Continue. Include in PR body: "Coverage gate: OVERRIDDEN at {X}%."
+
+**Coverage percentage undetermined:** If the coverage diagram doesn't produce a clear numeric percentage (ambiguous output, parse error), **skip the gate** with: "Coverage gate: could not determine percentage — skipping." Do not default to 0% or block.
+
+**Test-only diffs:** Skip the gate (same as the existing fast-path).
+
+**100% coverage:** "Coverage gate: PASS (100%)." Continue.`);

+
+### Diff-aware (automatic when on a feature branch with no URL)
+
+This is the **primary mode** for developers verifying their work. When the user says \`/qa\` without a URL and the repo is on a feature branch, automatically:
+
+1. **Analyze the branch diff** to understand what changed:
+   \`\`\`bash
+   git diff main...HEAD --name-only
+   git log main..HEAD --oneline
+   \`\`\`
+
+2. **Identify affected pages/routes** from the changed files:
+   - Controller/route files → which URL paths they serve
+   - View/template/component files → which pages render them
+   - Model/service files → which pages use those models (check controllers that reference them)
+   - CSS/style files → which pages include those stylesheets
+   - API endpoints → test them directly with \`$B js "await fetch('/api/...')"\`
+   - Static pages (markdown, HTML) → navigate to them directly
+
+   **If no obvious pages/routes are identified from the diff:** Do not skip browser testing. The user invoked /qa because they want browser-based verification. Fall back to Quick mode — navigate to the homepage, follow the top 5 navigation targets, check console for errors, and test any interactive elements found. Backend, config, and infrastructure changes affect app behavior — always verify the app still works.
+
+3. **Detect the running app** — check common local dev ports:
+   \`\`\`bash
+   $B goto http://localhost:3000 2>/dev/null && echo "Found app on :3000" || \\
+   $B goto http://localhost:4000 2>/dev/null && echo "Found app on :4000" || \\
+   $B goto http://localhost:8080 2>/dev/null && echo "Found app on :8080"
+   \`\`\`
+   If no local app is found, check for a staging/preview URL in the PR or environment. If nothing works, ask the user for the URL.
+
+4. **Test each affected page/route:**
+   - Navigate to the page
+   - Take a screenshot
+   - Check console for errors
+   - If the change was interactive (forms, buttons, flows), test the interaction end-to-end
+   - Use \`snapshot -D\` before and after actions to verify the change had the expected effect
+
+5. **Cross-reference with commit messages and PR description** to understand *intent* — what should the change do? Verify it actually does that.
+
+6. **Check TODOS.md** (if it exists) for known bugs or issues related to the changed files. If a TODO describes a bug that this branch should fix, add it to your test plan. If you find a new bug during QA that isn't in TODOS.md, note it in the report.
+
+7. **Report findings** scoped to the branch changes:
+   - "Changes tested: N pages/routes affected by this branch"
+   - For each: does it work? Screenshot evidence.
+   - Any regressions on adjacent pages?
+
+**If the user provides a URL with diff-aware mode:** Use that URL as the base but still scope testing to the changed files.
+
+### Full (default when URL is provided)
+Systematic exploration. Visit every reachable page. Document 5-10 well-evidenced issues. Produce health score. Takes 5-15 minutes depending on app size.
+
+### Quick (\`--quick\`)
+30-second smoke test. Visit homepage + top 5 navigation targets. Check: page loads? Console errors? Broken links? Produce health score. No detailed issue documentation.
+
+### Regression (\`--regression <baseline>\`)
+Run full mode, then load \`baseline.json\` from a previous run. Diff: which issues are fixed? Which are new? What's the score delta? Append regression section to report.
+
+---
+
+## Workflow
+
+### Phase 1: Initialize
+
+1. Find browse binary (see Setup above)
+2. Create output directories
+3. Copy report template from \`qa/templates/qa-report-template.md\` to output dir
+4. Start timer for duration tracking
+
+### Phase 2: Authenticate (if needed)
+
+**If the user specified auth credentials:**
+
+\`\`\`bash
+$B goto <login-url>
+$B snapshot -i                    # find the login form
+$B fill @e3 "user@example.com"
+$B fill @e4 "[REDACTED]"         # NEVER include real passwords in report
+$B click @e5                      # submit
+$B snapshot -D                    # verify login succeeded
+\`\`\`
+
+**If the user provided a cookie file:**
+
+\`\`\`bash
+$B cookie-import cookies.json
+$B goto <target-url>
+\`\`\`
+
+**If 2FA/OTP is required:** Ask the user for the code and wait.
+
+**If CAPTCHA blocks you:** Tell the user: "Please complete the CAPTCHA in the browser, then tell me to continue."
+
+### Phase 3: Orient
+
+Get a map of the application:
+
+\`\`\`bash
+$B goto <target-url>
+$B snapshot -i -a -o "$REPORT_DIR/screenshots/initial.png"
+$B links                          # map navigation structure
+$B console --errors               # any errors on landing?
+\`\`\`
+
+**Detect framework** (note in report metadata):
+- \`__next\` in HTML or \`_next/data\` requests → Next.js
+- \`csrf-token\` meta tag → Rails
+- \`wp-content\` in URLs → WordPress
+- Client-side routing with no page reloads → SPA
+
+**For SPAs:** The \`links\` command may return few results because navigation is client-side. Use \`snapshot -i\` to find nav elements (buttons, menu items) instead.
+
+### Phase 4: Explore
+
+Visit pages systematically. At each page:
+
+\`\`\`bash
+$B goto <page-url>
+$B snapshot -i -a -o "$REPORT_DIR/screenshots/page-name.png"
+$B console --errors
+\`\`\`
+
+Then follow the **per-page exploration checklist** (see \`qa/references/issue-taxonomy.md\`):
+
+1. **Visual scan** — Look at the annotated screenshot for layout issues
+2. **Interactive elements** — Click buttons, links, controls. Do they work?
+3. **Forms** — Fill and submit. Test empty, invalid, edge cases
+4. **Navigation** — Check all paths in and out
+5. **States** — Empty state, loading, error, overflow
+6. **Console** — Any new JS errors after interactions?
+7. **Responsiveness** — Check mobile viewport if relevant:
+   \`\`\`bash
+   $B viewport 375x812
+   $B screenshot "$REPORT_DIR/screenshots/page-mobile.png"
+   $B viewport 1280x720
+   \`\`\`
+
+**Depth judgment:** Spend more time on core features (homepage, dashboard, checkout, search) and less on secondary pages (about, terms, privacy).
+
+**Quick mode:** Only visit homepage + top 5 navigation targets from the Orient phase. Skip the per-page checklist — just check: loads? Console errors? Broken links visible?
+
+### Phase 5: Document
+
+Document each issue **immediately when found** — don't batch them.
+
+**Two evidence tiers:**
+
+**Interactive bugs** (broken flows, dead buttons, form failures):
+1. Take a screenshot before the action
+2. Perform the action
+3. Take a screenshot showing the result
+4. Use \`snapshot -D\` to show what changed
+5. Write repro steps referencing screenshots
+
+\`\`\`bash
+$B screenshot "$REPORT_DIR/screenshots/issue-001-step-1.png"
+$B click @e5
+$B screenshot "$REPORT_DIR/screenshots/issue-001-result.png"
+$B snapshot -D
+\`\`\`
+
+**Static bugs** (typos, layout issues, missing images):
+1. Take a single annotated screenshot showing the problem
+2. Describe what's wrong
+
+\`\`\`bash
+$B snapshot -i -a -o "$REPORT_DIR/screenshots/issue-002.png"
+\`\`\`
+
+**Write each issue to the report immediately** using the template format from \`qa/templates/qa-report-template.md\`.
+
+### Phase 6: Wrap Up
+
+1. **Compute health score** using the rubric below
+2. **Write "Top 3 Things to Fix"** — the 3 highest-severity issues
+3. **Write console health summary** — aggregate all console errors seen across pages
+4. **Update severity counts** in the summary table
+5. **Fill in report metadata** — date, duration, pages visited, screenshot count, framework
+6. **Save baseline** — write \`baseline.json\` with:
+   \`\`\`json
+   {
+     "date": "YYYY-MM-DD",
+     "url": "<target>",
+     "healthScore": N,
+     "issues": [{ "id": "ISSUE-001", "title": "...", "severity": "...", "category": "..." }],
+     "categoryScores": { "console": N, "links": N, ... }
+   }
+   \`\`\`
+
+**Regression mode:** After writing the report, load the baseline file. Compare:
+- Health score delta
+- Issues fixed (in baseline but not current)
+- New issues (in current but not baseline)
+- Append the regression section to the report
+
+---
+
+## Health Score Rubric
+
+Compute each category score (0-100), then take the weighted average.
+
+### Console (weight: 15%)
+- 0 errors → 100
+- 1-3 errors → 70
+- 4-10 errors → 40
+- 10+ errors → 10
+
+### Links (weight: 10%)
+- 0 broken → 100
+- Each broken link → -15 (minimum 0)
+
+### Per-Category Scoring (Visual, Functional, UX, Content, Performance, Accessibility)
+Each category starts at 100. Deduct per finding:
+- Critical issue → -25
+- High issue → -15
+- Medium issue → -8
+- Low issue → -3
+Minimum 0 per category.
+
+### Weights
+| Category | Weight |
+|----------|--------|
+| Console | 15% |
+| Links | 10% |
+| Visual | 10% |
+| Functional | 20% |
+| UX | 15% |
+| Performance | 10% |
+| Content | 5% |
+| Accessibility | 15% |
+
+### Final Score
+\`score = Σ (category_score × weight)\`
+
+---
+
+## Framework-Specific Guidance
+
+### Next.js
+- Check console for hydration errors (\`Hydration failed\`, \`Text content did not match\`)
+- Monitor \`_next/data\` requests in network — 404s indicate broken data fetching
+- Test client-side navigation (click links, don't just \`goto\`) — catches routing issues
+- Check for CLS (Cumulative Layout Shift) on pages with dynamic content
+
+### Rails
+- Check for N+1 query warnings in console (if development mode)
+- Verify CSRF token presence in forms
+- Test Turbo/Stimulus integration — do page transitions work smoothly?
+- Check for flash messages appearing and dismissing correctly
+
+### WordPress
+- Check for plugin conflicts (JS errors from different plugins)
+- Verify admin bar visibility for logged-in users
+- Test REST API endpoints (\`/wp-json/\`)
+- Check for mixed content warnings (common with WP)
+
+### General SPA (React, Vue, Angular)
+- Use \`snapshot -i\` for navigation — \`links\` command misses client-side routes
+- Check for stale state (navigate away and back — does data refresh?)
+- Test browser back/forward — does the app handle history correctly?
+- Check for memory leaks (monitor console after extended use)
+
+---
+
+## Important Rules
+
+1. **Repro is everything.** Every issue needs at least one screenshot. No exceptions.
+2. **Verify before documenting.** Retry the issue once to confirm it's reproducible, not a fluke.
+3. **Never include credentials.** Write \`[REDACTED]\` for passwords in repro steps.
+4. **Write incrementally.** Append each issue to the report as you find it. Don't batch.
+5. **Never read source code.** Test as a user, not a developer.
+6. **Check console after every interaction.** JS errors that don't surface visually are still bugs.
+7. **Test like a user.** Use realistic data. Walk through complete workflows end-to-end.
+8. **Depth over breadth.** 5-10 well-documented issues with evidence > 20 vague descriptions.
+9. **Never delete output files.** Screenshots and reports accumulate — that's intentional.
+10. **Use \`snapshot -C\` for tricky UIs.** Finds clickable divs that the accessibility tree misses.
+11. **Show screenshots to the user.** After every \`$B screenshot\`, \`$B snapshot -a -o\`, or \`$B responsive\` command, use the Read tool on the output file(s) so the user can see them inline. For \`responsive\` (3 files), Read all three. This is critical — without it, screenshots are invisible to the user.
+12. **Never refuse to use the browser.** When the user invokes /qa or /qa-only, they are requesting browser-based testing. Never suggest evals, unit tests, or other alternatives as a substitute. Even if the diff appears to have no UI changes, backend changes affect app behavior — always open the browser and test.`;

+
+1. Read \`CHANGELOG.md\` header to know the format.
+
+2. **First, enumerate every commit on the branch:**
+   \`\`\`bash
+   git log <base>..HEAD --oneline
+   \`\`\`
+   Copy the full list. Count the commits. You will use this as a checklist.
+
+3. **Read the full diff** to understand what each commit actually changed:
+   \`\`\`bash
+   git diff <base>...HEAD
+   \`\`\`
+
+4. **Group commits by theme** before writing anything. Common themes:
+   - New features / capabilities
+   - Performance improvements
+   - Bug fixes
+   - Dead code removal / cleanup
+   - Infrastructure / tooling / tests
+   - Refactoring
+
+5. **Write the CHANGELOG entry** covering ALL groups:
+   - If existing CHANGELOG entries on the branch already cover some commits, replace them with one unified entry for the new version
+   - Categorize changes into applicable sections:
+     - \`### Added\` — new features
+     - \`### Changed\` — changes to existing functionality
+     - \`### Fixed\` — bug fixes
+     - \`### Removed\` — removed features
+   - Write concise, descriptive bullet points
+   - Insert after the file header (line 5), dated today
+   - Format: \`## [X.Y.Z.W] - YYYY-MM-DD\`
+   - **Voice:** Lead with what the user can now **do** that they couldn't before. Use plain language, not implementation details. Never mention TODOS.md, internal tracking, or contributor-facing details.
+
+6. **Cross-check:** Compare your CHANGELOG entry against the commit list from step 2.
+   Every commit must map to at least one bullet point. If any commit is unrepresented,
+   add it now. If the branch has N commits spanning K themes, the CHANGELOG must
+   reflect all K themes.
+
+**Do NOT ask the user to describe changes.** Infer from the diff and commit history.`;
