+You are entering the **od-contribute** flow.
+
+User input (may be empty): `$ARGUMENTS`
+
+## What to do right now
+
+1. **Load the skill** by invoking the `od-contribute` skill via the Skill tool. The skill owns the full execution playbook — do not reimplement it inline.
+
+2. **Pass the user input forward**:
+   - If `$ARGUMENTS` is one of `skill`, `design-system`, `i18n`, `docs`, `bug` (or a recognizable Chinese / English equivalent), pre-select that branch and skip the type-picking `AskUserQuestion` in Step 2.
+   - Otherwise, the skill will ask the user via `AskUserQuestion`.
+
+3. **Honor the interactive contract**:
+   - Always run the prerequisite check first (`gh` installed + authed). If it fails, surface the install/auth hint and stop — do not try workarounds.
+   - Always show the preview + require explicit confirmation before pushing or opening any PR/issue.
+   - At the end, print the PR or issue URL on its own line so the user can click through.
+
+Begin by invoking the skill now.

+description: One-click contribution flow for Open Design (nexu-io/open-design) — even for non-coders. Pick one of four cards (ship a Skill or Design System you made with OD; translate docs; fix a typo / write a blog; report a bug), the agent validates and opens a PR (or issue) for you. Trigger words contribute to open design, ship my OD skill, ship my OD design system, translate OD docs, report an OD bug, od-contribute.

+
+# od-contribute — first-contribution flow for Open Design
+
+Locked to `nexu-io/open-design`. Branches by **contribution type**, not by issue. Replaces the dev-loop with type-specific no-code validators. Designed so a product user with zero coding background can ship a real PR.
+
+## Language
+
+Mirror the user's language in every user-facing message — `AskUserQuestion` labels and descriptions, status updates, error explanations. Detect from their first message; when uncertain, default to English.
+
+**Generated artifacts (PR titles, commit messages, PR/issue body files, branch names) MUST be English** regardless of the user's chat language. GitHub conventions, maintainer review, and search all assume English. The templates under `templates/` are already English — keep them that way when rendering.
+
+Scripts live under `scripts/`. Source the shared helpers from any script:
+
+```bash
+source "$(dirname "$0")/config.sh"
+```
+
+`SKILL_DIR` below = the directory that contains this `SKILL.md`.
+
+---
+
+## Step 1 — Prereq check (always first)
+
+```bash
+bash "$SKILL_DIR/scripts/check-prereqs.sh"
+```
+
+- Exit 0: capture `GH_USER=<login>` from stdout. Default `TARGET_FORK="${GH_USER}/open-design"`.
+- Exit 2: surface the printed install / auth hint **verbatim** and stop. Do not attempt token workarounds.
+
+If `gh repo view "$TARGET_FORK"` fails, ask the user (one `AskUserQuestion`) whether to fork now via `gh repo fork nexu-io/open-design --clone=false`. Default to yes.
+
+## Step 2 — Pick contribution type
+
+Single `AskUserQuestion` (header: "Contribution", multiSelect: false), four options. Translate option labels/descriptions into the user's chat language; the branch routing is unchanged.
+
+1. **🎨 Ship something I made with OD** — _a Skill, Design System, HyperFrame, or template I want to contribute upstream_ → branch `3a`
+2. **🌍 Translate OD docs** — _README / QUICKSTART / CONTRIBUTING into a new language_ → branch `3b`
+3. **📝 Fix docs / write a blog / fix a typo** — _typo fix, dead link, use-case writeup_ → branch `3c`
+4. **🐛 Report a bug** — _something broke; I'll help turn it into a high-quality issue_ → branch `3d` (issue path, no PR)
+
+Each branch below is self-contained. Steps 7–8 (preview + push) are shared across branches `3a`/`3b`/`3c`. Branch `3d` skips them entirely.
+
+---
+
+### Step 3a — OD product submission (Skill / Design System)
+
+**3a.1** Ask user: "What's the local path to the artifact you want to ship?" (single free-text, translated into the user's chat language). Common: a folder path (Skill) or a single `DESIGN.md` file (Design System).
+
+**3a.2** Sniff type:
+
+```bash
+# Skill: folder containing SKILL.md with frontmatter.
+# Design System: file matching DESIGN.md anatomy.
+```
+
+If ambiguous, ask the user to confirm.
+
+**3a.3** Run setup:
+
+```bash
+bash "$SKILL_DIR/scripts/setup-workspace.sh" skill <slug>
+# or
+bash "$SKILL_DIR/scripts/setup-workspace.sh" design-system <slug>
+```
+
+`<slug>` is `od::slugify` of the Skill `name` frontmatter field or of the brand name. Capture `WORKDIR` from stdout.
+
+**3a.4** Copy artifact into workspace at the right target dir:
+- Skill → `$WORKDIR/skills/<slug>/`
+- Design System → `$WORKDIR/design-systems/<brand-slug>/DESIGN.md` (+ any sibling assets in the same folder)
+
+**3a.5** Validate:
+
+```bash
+bash "$SKILL_DIR/scripts/validate-skill-submission.sh" "$WORKDIR/skills/<slug>"
+# or, with 1-2 reference DESIGN.md files passed in:
+bash "$SKILL_DIR/scripts/validate-design-system.sh" \
+  "$WORKDIR/design-systems/<slug>/DESIGN.md" \
+  --reference "$WORKDIR/design-systems/airbnb/DESIGN.md" \
+  --reference "$WORKDIR/design-systems/apple/DESIGN.md"
+```
+
+If validation fails, surface the FAIL lines verbatim, ask the user to fix, retry. **Never push a failing artifact.**
+
+**3a.6** Ask 3 short questions via `AskUserQuestion` (translate the labels into the user's chat language):
+- "What name should we credit you under in the PR?" — free-text
+- "One-line pitch for this Skill / Design System?" — free-text
+- "Path to a screenshot (optional)?" — free-text
+
+**3a.7** Render `templates/PR-BODY-skill.md` (or `PR-BODY-design-system.md`) with substitutions:
+- `{{SKILL_NAME}}`, `{{SKILL_SLUG}}` (or `{{BRAND_NAME}}`, `{{BRAND_SLUG}}`)
+- `{{PITCH}}` (the one-line)
+- `{{MOTIVATION}}` (free-text — agent can offer to draft this from the skill body, but user confirms)
+- `{{TRY_PROMPT}}` (a prompt they recommend trying — agent suggests a default, user confirms)
+- `{{SCREENSHOT_BLOCK}}` (Markdown image block if a screenshot path was given, else empty)
+- `{{DISCORD_INVITE}}` from `$OD_DISCORD_INVITE`
+
+Write to `$WORKDIR/.od-contrib/PR-BODY.md`.
+
+→ Jump to **Step 7**.
+
+---
+
+### Step 3b — i18n translation
+
+**3b.1** Setup workspace (slug = `translate-<doc>-<lang>` if known, else `translate`):
+
+```bash
+bash "$SKILL_DIR/scripts/setup-workspace.sh" i18n translate
+# capture WORKDIR
+```
+
+**3b.2** Discover gaps:
+
+```bash
+bash "$SKILL_DIR/scripts/discover-i18n-gaps.sh" "$WORKDIR" > /tmp/od-i18n-gaps.json
+```
+
+Each line is JSON. Rank by:
+- `status: "missing"` first (missing language is highest leverage)
+- then `status: "stale"` ordered by `english_commits_since_translation` desc
+- README family before QUICKSTART before CONTRIBUTING
+
+**3b.3** Take the top 3–4 gaps and present via `AskUserQuestion` (header: "Translation target"). Each option label like: `README → 한국어 (Korean)` / `QUICKSTART (zh-CN) refresh — 12 commits behind`. Translate the header text into the user's chat language but keep the option labels descriptive (the language names belong in their native script).
+
+**3b.4** Once user picks, **rename branch** to be specific:
+```bash
+git -C "$WORKDIR" branch -m "od-contrib/i18n/<doc>-<lang>-<date>"
+```
+(or pre-set the slug in step 3b.1 if the user confirmed earlier.)
+
+**3b.5** Translate. Read the English source. Translate **structure-preserving**:
+- Code blocks: leave untranslated
+- Brand / product names: leave untranslated
+- Filenames in inline code: leave untranslated
+- Image / link targets: leave untranslated; if a localized version of a linked doc exists, swap the link to the localized file
+- Headings: translate, keep the heading depth identical
+- Tables: translate cell text only, keep alignment / pipes
+
+Write the result to `$WORKDIR/<TRANSLATED_PATH>` (e.g. `QUICKSTART.es.md`). Show user a unified diff vs. the English source for visual sanity-check (line-count delta within ±15% is a healthy signal).
+
+**3b.6** Validate the translated file against the English source. The `--reference` flag tells the validator to ignore relative refs that were already broken in the source — OD docs frequently link to website route slugs (e.g. `skills/blog-post/`) that aren't files on disk; we don't want a structure-preserving translation to fail because of pre-existing dead refs.
+
+```bash
+bash "$SKILL_DIR/scripts/validate-markdown.sh" \
+  "$WORKDIR/<TRANSLATED_PATH>" \
+  --reference "$WORKDIR/<ENGLISH_PATH>"
+```
+
+If FAIL → surface verbatim, fix, retry.
+
+**3b.7** Render `templates/PR-BODY-i18n.md` with `{{DOC_NAME}}`, `{{LANG_DISPLAY_NAME}}`, `{{LANG_CODE}}`, `{{TRANSLATED_PATH}}`, `{{ENGLISH_PATH}}`, `{{STATUS}}`, `{{TRANSLATION_NOTES}}` (one paragraph from the agent: anything tricky, untranslated terms it kept, etc.), `{{DISCORD_INVITE}}`.
+
+→ **Step 7**.
+
+---
+
+### Step 3c — Docs / blog / typo
+
+**3c.1** Setup workspace (slug `docs`):
+
+```bash
+bash "$SKILL_DIR/scripts/setup-workspace.sh" docs <slug>
+```
+
+**3c.2** Ask user (one `AskUserQuestion`):
+1. **Auto-discover small fixes** (run discover-doc-gaps, pick something)
+2. **I have a specific fix in mind** (free-text)
+3. **I want to write a blog / case study** (free-text — what's the use case?)
+
+**3c.3 (Auto-discover branch)** Run:
+
+```bash
+bash "$SKILL_DIR/scripts/discover-doc-gaps.sh" "$WORKDIR" > /tmp/od-doc-gaps.json
+```
+
+Group by `kind` (typo / deadlink / todo). Show the user up to 6 candidates via `AskUserQuestion`. Once picked, apply the fix in code (typo: replace word; deadlink: ask user for the new URL; todo: that's a proper task, ask user to write the missing prose).
+
+**3c.4 (Specific-fix branch)** Read the file, apply user's described change. Confirm via diff.
+
+**3c.5 (Blog branch)** First check whether OD has a blog directory:
+
+```bash
+ls "$WORKDIR/docs" 2>/dev/null
+```
+
+If a `docs/blog/` or similar exists, place the new post there. If not, ask the user where it should live, defaulting to `docs/<slug>.md`. Generate an outline → user fills in user-specific bits (their use case, screenshots, the prompt they used, the rendered output) → agent stitches into a final Markdown.
+
+**3c.6** Validate every changed/added file. For files that already exist in the repo (typo fix, dead-link fix, doc edit), pass `--reference` pointing at HEAD's version so we only fail on relative refs the user *introduced*, not on pre-existing route slugs:
+
+```bash
+# For modifications to existing files:
+git -C "$WORKDIR" show "HEAD:<path>" > "/tmp/od-contrib-orig-<basename>" 2>/dev/null
+bash "$SKILL_DIR/scripts/validate-markdown.sh" \
+  "$WORKDIR/<changed-path>" \
+  --reference "/tmp/od-contrib-orig-<basename>"
+
+# For brand-new files (e.g. a blog post the user is creating from scratch),
+# omit --reference. The validator will skip the relative-ref check entirely
+# (since it can't tell route slugs from real paths in isolation).
+```
+
+**3c.7** Render `templates/PR-BODY-docs.md` with `{{ONE_LINE_SUMMARY}}`, `{{DETAILS}}`, `{{FILES_LIST}}`, `{{DISCORD_INVITE}}`.
+
+→ **Step 7**.
+
+---
+
+### Step 3d — Bug report (issue path, no PR)
+
+**3d.1** Read OD's actual schema at runtime to make sure we mirror it:
+
+```bash
+gh api "repos/${TARGET_REPO}/contents/.github/ISSUE_TEMPLATE/bug-report.yml" --jq .content | base64 -d > /tmp/od-bug-report.yml
+```
+
+If the schema has drifted from the template (`templates/ISSUE-BODY-bug.md`), regenerate the body to match.
+
+**3d.2** Ask the user via `AskUserQuestion`, one structured prompt per critical field. Use **plain language**, not the YAML field names:
+
+| Bug-report field | Prompt to user |
+|---|---|
+| `description` | "What went wrong? One sentence is fine." |
+| `steps` | "How can I reproduce it? Walk me through step by step." |
+| `expected` | "What did you expect to happen?" |
+| `version` | "Which OD version are you running? (About menu, or `od --version`)" |
+| `platform` | dropdown: macOS (Apple Silicon) / macOS (Intel) / Windows / Linux / Other |
+| `logs` | "Any error logs you can paste? Skip if you don't have them." |
+| `screenshots` | "Path to a screenshot? Skip if you don't have one." |
+
+Translate every prompt above into the user's chat language at runtime.
+
+**3d.3** Auto-collect what we can (these don't need to ask the user):
+- OS family from `uname`
+- Node version from `node -v` if relevant
+
+**3d.4** Dedupe: extract 3–5 keywords from the description, run:
+
+```bash
+gh search issues "<keywords>" --repo "$TARGET_REPO" --state open --limit 5 --json number,title,url
+```
+
+If matches exist, present them to the user via `AskUserQuestion` (translate to user's language): "These existing issues look related. Do you want to: (a) comment on an existing one, (b) open a new issue anyway, (c) cancel?"
+
+**3d.5** If proceeding with new issue, render `templates/ISSUE-BODY-bug.md` and submit:
+
+```bash
+bash "$SKILL_DIR/scripts/create-issue.sh" \
+  --title "$TITLE" \
+  --body-file "$WORKDIR_OR_TMP/.od-contrib/ISSUE-BODY.md" \
+  --dedupe-keywords "<keywords>"
+```
+
+**3d.6** Print the issue URL on its own line. **Do not** push branches or open PRs from this branch.
+
+---
+
+## Step 7 — Preview + confirm (shared, PR branches only)
+
+Show the user a clean summary:
+
+```text
+About to commit:
+  Branch:  od-contrib/<type>/<slug>-<date>
+  Files:
+    + skills/foo/SKILL.md            (1.2 KB)
+    + skills/foo/preview.png         (54 KB)
+  Push to:  <fork or upstream>
+  Open PR:  nexu-io/open-design:main ← <fork>:<branch>
+```
+
+Then `git -C "$WORKDIR" diff --stat` and a `head -40` of the rendered PR body for visual sanity.
+
+Required `AskUserQuestion` confirmation (translate to user's language): **"Push this PR?"** with three options:
+- **Ship it** — proceed to Step 8
+- **Let me revise** — return to the relevant Step 3 sub-step
+- **Cancel** — leave the workspace on disk, tell the user the path so they can return later, exit
+
+Never push without an explicit "Ship it".
+
+## Step 8 — Push & open PR
+
+```bash
+bash "$SKILL_DIR/scripts/create-pr.sh" \
+  --workdir "$WORKDIR" \
+  --type "<skill|design-system|i18n|docs>" \
+  --title "<PR title from references/newcomer-tone.md>" \
+  --body-file "$WORKDIR/.od-contrib/PR-BODY.md"
+```
+
+Print the PR URL on its own line. Done.
+
+---
+
+## Safety rails (mandatory)
+
+- Never push to `main` / `master` / `develop`. The push scripts refuse.
+- Never `--force` push. Just don't.
+- All workspace activity stays under `$OD_WORK_ROOT` (default `$HOME/od-contrib-work`). `od::assert_in_workroot` enforces this.
+- Bug-report path **always** runs the dedupe search before `gh issue create`.
+- Honor user memory: skip GitHub user `xxiaoxiong` from any contributor lookup ([[feedback_no_outreach_xxiaoxiong]]).
+
+## When NOT to use this skill
+
+- The user wants to fix a daemon / web bug or add a feature with code changes → use `auto-github-contributor` instead (it has the TDD loop). This skill deliberately doesn't run lint/typecheck/tests because content paths don't need them.
+- The user wants to *generate* a Skill / Design System from scratch → that's Open Design itself. Run OD first, get an artifact, then come back here to ship it.

+# What an OD design-system folder looks like
+
+Reference for the `od-contribute` skill's `validate-design-system.sh` step.
+
+> **Authoritative source**: read 1–2 existing folders under `design-systems/` in `nexu-io/open-design` at runtime — the conventions evolve as new systems land.
+
+## Minimum viable design system
+
+```
+design-systems/<brand-slug>/
+└── DESIGN.md          # required — the brand brief OD loads
+```
+
+A few systems include extras: `components.html`, `tokens.css`. These are optional, referenced from `DESIGN.md` if present.
+
+## DESIGN.md structure (observed convention)
+
+H1 with the brand name, then a blockquote with category + one-sentence pitch, then numbered H2 sections. Looking at established systems (`airbnb`, `apple`, etc.), the typical section list is:
+
+```markdown
+# Design System Inspired by <Brand>
+
+> Category: <e.g. E-Commerce & Retail>
+> <one-sentence pitch>
+
+## 1. Visual Theme & Atmosphere
+## 2. Color Palette & Roles
+## 3. Typography
+## 4. Layout & Spacing
+## 5. Components
+## 6. Motion & Interaction
+## 7. Iconography & Imagery
+## 8. Voice & Tone
+## 9. Edge Cases & Variations
+```
+
+Section ordering and exact titles vary — the validator only checks **structural overlap with reference systems**, not exact heading text. ≥30% overlap with the union of headings from existing systems is enough to pass.
+
+## What the validator actually enforces
+
+1. File is non-empty and has at least one H1.
+2. ≥30% heading overlap with reference DESIGN.md files (when references are passed in).
+3. No `../` relative paths that would resolve outside `design-systems/<brand>/`.
+
+That's deliberately loose — DESIGN.md is a creative brief, not a schema.
+
+## Don'ts
+
+- Don't reference assets outside the brand folder.
+- Don't paste binary fonts; use a CSS `@font-face` reference and let OD resolve at runtime.
+- Don't use real customer logos / proprietary brand assets you don't have rights to (the validator won't catch this — it's a maintainer-review concern).

+# Newcomer tone — voice rules for PR / issue text
+
+Per user feedback ([[feedback_outreach_minimal]]), keep it minimal. The PR body is the **only** place we get to shape the maintainer's first impression of this contributor — make it warm, brief, and useful.
+
+## Hard rules
+
+1. **Always end the PR body with two things:**
+   - "👋 This is my first OD contribution." (or a similar one-line warmth)
+   - The OD Discord invite: <https://discord.gg/qhbcCH8Am4> (read from `OD_DISCORD_INVITE` env, never hardcode)
+2. **Never claim more than the PR actually does.** A typo fix is a typo fix — don't dress it up as "improving documentation quality" or list 5 fake checkboxes.
+3. **Plain language only.** No "ergonomic", "DX", "stakeholder", "stack rank". Talk like a friendly user, not a startup blog.
+4. **No emojis except the opening 👋 and one optional 🎨 / 🌍 / 📝 / 🐛 in the title or first line.** OD is design-loving but the maintainers read a *lot* of PRs.
+
+## Soft rules
+
+- Lead with **what changed**, not why or how. Maintainers can read the diff for the how.
+- "Why" gets at most 2–3 sentences. If it needs more, the work is too big for this skill — open an issue instead.
+- One screenshot if the change is visible. Zero is fine.
+- The "checklist" should reflect what the validator actually checked, not a generic ceremonial list.
+
+## Anti-patterns (do not do these)
+
+- **Don't** write an "ask" section. Don't say "please review when you have time" — the PR is the ask.
+- **Don't** invite the maintainer to call / DM you. Discord is the channel.
+- **Don't** apologize. ("Sorry if this isn't right" — the maintainer will tell you if it isn't.)
+- **Don't** include a "TL;DR" — if the summary needs a TL;DR, the summary is too long.
+
+## Title conventions (for `git commit` and `gh pr create --title`)
+
+| Type | Format | Example |
+|---|---|---|
+| Skill | `Add Skill: <name>` | `Add Skill: invoice-template` |
+| Design System | `Add Design System: <brand>` | `Add Design System: notion` |
+| i18n | `Translate <doc> to <Lang>` | `Translate QUICKSTART to Spanish` |
+| i18n (refresh) | `Update <Lang> translation of <doc>` | `Update zh-CN translation of README` |
+| Docs typo | `Fix typo in <file>` | `Fix typo in README.md` |
+| Docs other | `<verb> <noun> in <where>` | `Clarify daemon setup in QUICKSTART` |
+| Bug (issue title) | `<observed> on <surface>` | `Preview iframe is blank on Safari 17` |
+
+## When to ask before writing
+
+If the user wants to ship something whose tone is unusual (a manifesto blog post, a contentious refactor, naming a brand after a real company without rights), pause and ask the user. Better to skip the PR than ship something the maintainer will close politely.

+# OD repo map — what goes where
+
+Mirrors `nexu-io/open-design` `CONTRIBUTING.md` so the skill doesn't need to re-fetch it on every run. **If this drifts from upstream CONTRIBUTING.md, upstream wins** — re-read the live file when in doubt.
+
+## Three high-leverage contribution surfaces (per OD's CONTRIBUTING.md)
+
+| If you want to… | You're really adding | Where it lives | Ship size |
+|---|---|---|---|
+| Make OD render a new kind of artifact | a **Skill** | `skills/<your-skill>/` | one folder, ~2 files |
+| Make OD speak a new brand's visual language | a **Design System** | `design-systems/<brand>/DESIGN.md` | one Markdown file |
+| Hook up a new coding-agent CLI | an **Agent adapter** | `apps/daemon/src/agents.ts` | ~10 lines (code — out of scope for this skill) |
+| Improve docs, port a section to fr / de / zh-CN, fix typos | docs | `README.md`, `README.fr.md`, `README.de.md`, `README.zh-CN.md`, `docs/`, `QUICKSTART.md` | one PR |
+
+## Localized doc files we know about
+
+| Doc family | English source | Translations seen on disk (as of plan time) |
+|---|---|---|
+| README | `README.md` | ar, de, es, fr, ja-JP, ko, pt-BR, ru, tr, uk, zh-CN, zh-TW |
+| QUICKSTART | `QUICKSTART.md` | de, fr, ja-JP, pt-BR, zh-CN, zh-TW |
+| CONTRIBUTING | `CONTRIBUTING.md` | de, fr, ja-JP, pt-BR, zh-CN |
+| MAINTAINERS | `MAINTAINERS.md` | de, fr, ja-JP, pt-BR, zh-CN |
+
+The skill `discover-i18n-gaps.sh` does NOT trust this table — it scans the workspace at runtime. Use this list only when you need to seed an `AskUserQuestion` card without a workspace.
+
+## Issue templates
+
+- `bug-report.yml` — required fields: description, steps to reproduce, expected, version, platform.
+- `feature-request.yml` — out of scope for this skill (feature requests should come from product, not auto-routed.)
+- `preview-v0.8.0-feedback.yml` — branch-specific.
+
+## Out-of-scope surfaces (don't touch from this skill)
+
+- `apps/daemon/src/` — daemon code. Requires real review.
+- `apps/web/src/` — web app code. Requires real review.
+- `packages/`, `plugins/`, `tools/` — internal libs.
+- `e2e/` — Playwright-driven; non-trivial to author.
+
+If a user asks to contribute to those surfaces, suggest the original `auto-github-contributor` skill (TDD pipeline) instead.

+# What an OD skill folder looks like
+
+Reference for the `od-contribute` skill's `validate-skill-submission.sh` step and for guiding a user through assembling a Skill submission.
+
+> **Authoritative source**: read 1–2 existing folders under `skills/` in `nexu-io/open-design` at runtime — conventions evolve faster than this doc.
+
+## Minimum viable skill
+
+```
+skills/<your-skill>/
+└── SKILL.md          # required, must have YAML frontmatter
+```
+
+That's it. Many of the simplest skills in OD are exactly that: one Markdown file in one folder.
+
+## Frontmatter — what `validate-skill-submission.sh` requires
+
+```yaml
+---
+name: <kebab-case-slug>           # required; usually matches the folder name
+description: |                    # required; one paragraph; what the skill does in user terms
+  Generate and iterate ad creative including headlines, descriptions, and primary text.
+triggers:                         # optional but strongly recommended
+  - "ad creative"
+  - "ad headline"
+od:                               # optional; OD-specific metadata
+  mode: design-system             # or other modes; check existing skills
+  category: <category-slug>
+  upstream: "https://github.com/..."  # if the skill was lifted from somewhere
+---
+```
+
+**Required by validator**: `name`, `description`. Everything else is convention.
+
+## Body conventions (after the frontmatter)
+
+Looking at existing skills, the typical body has:
+
+1. `# <skill-name>` H1.
+2. A one-line "what it does" sentence.
+3. Optional `## Source` block when adapted from upstream (with attribution).
+4. `## How to use` with one or two example prompts the user might type.
+
+## When a skill folder needs more than `SKILL.md`
+
+- **Reference assets** — long prompt fragments, example outputs, image references — go alongside `SKILL.md` in the same folder, referenced via relative paths in `SKILL.md`.
+- **Subfolders** are fine: the validator only requires that every relative reference inside `SKILL.md` resolves and that no path escapes the skill folder.
+
+## Don'ts
+
+- Don't put runtime code in here. Skills are *content* — Markdown + maybe assets. Code adapters live in `apps/daemon/src/`.
+- Don't reference files outside `skills/<your-skill>/` — that breaks portability.
+- Don't put binaries you don't need (the lighter the folder, the easier the review).

 ## Validation strategy
 
 - After package, workspace, or command-entry changes, run `pnpm install` so workspace links and generated dist entries stay fresh.
+- For agent-stream / parser changes (`apps/daemon/src/claude-stream.ts`, `json-event-stream.ts`, `qoder-stream.ts`, etc.), replay a recorded session through the mock CLIs in `mocks/` to verify event shapes round-trip without burning provider budget. PATH-overlay activation: `export PATH="$PWD/mocks/bin:$PATH" OD_MOCKS_TRACE=<8-char-id> OD_MOCKS_NO_DELAY=1`. See `mocks/README.md` for the trace catalog and selection knobs.
 - Treat every `pnpm-lock.yaml` change as requiring a Nix pnpm deps hash refresh check. `nix/pnpm-deps.nix` is a generated lock artifact; use `pnpm nix:update-hash` only when intentionally maintaining Nix packaging, then re-run `nix flake check --print-build-logs --keep-going`. Contributors without Nix can rely on the PR `Validate workspace` gate, which now uploads or auto-applies the generated hash-only fix when possible.
 - Before marking regular work ready, run at least `pnpm guard` and `pnpm typecheck`, plus the package-scoped tests/builds that match the files changed. Do not use or add root `pnpm test`/`pnpm build` aliases.
 - For local web runtime loops, prefer `pnpm tools-dev run web --daemon-port <port> --web-port <port>`.

OpenAI-compatible covers OpenAI, Azure AI Foundry `/openai/v1`, DeepSeek, Groq, MiMo, OpenRouter, Ollama, LM Studio, and self-hosted vLLM; Azure OpenAI adds deployment URL + `api-version`; Google uses Gemini `:streamGenerateContent`.

 - **Tab persistence.** Every project remembers its open files and active tab in the `tabs` table. Reopen the project tomorrow and the workspace looks exactly the way you left it.
 - **Artifact lint API.** `POST /api/artifacts/lint` runs structural checks on a generated artifact (broken `<artifact>` framing, missing required side files, stale palette tokens) and returns findings the agent can read back into its next turn. The five-dim self-critique uses this to ground its score in real evidence, not vibes.
 - **Sidecar protocol + desktop automation.** Daemon, web, and desktop processes carry typed five-field stamps (`app · mode · namespace · ipc · source`) and expose a JSON-RPC IPC channel at `/tmp/open-design/ipc/<namespace>/<app>.sock`. `tools-dev inspect desktop status \| eval \| screenshot` drives that channel, so headless E2E works against a real Electron shell without bespoke harnesses ([`packages/sidecar-proto/`](packages/sidecar-proto/), [`apps/desktop/src/main/`](apps/desktop/src/main/)).

+// Regex matching fabricated role-marker lines injected by the model into
+// its own output. Anchored to start-of-line via (?:^|\n) so we don't
+// false-positive on user prose like "here is the ## user content".
+//
+// Scope (deliberately narrow): Markdown-style `## user` / `## assistant`
+// / `## assist` / `## system` only — these are the patterns the chat
+// host actually parses as turn boundaries (see `buildDaemonTranscript`
+// in apps/web/src/providers/daemon.ts). Chat-style markers like
+// `User:` / `Assistant:` / `Human:` / `AI:` are intentionally NOT
+// included, because:
+//   (1) The host never parses them as turn boundaries; a model emitting
+//       them does NOT cause the original #3247 security failure mode.
+//   (2) They collide with legitimate output far more often than the
+//       Markdown family (e.g., "User: bob@example.com", form labels,
+//       JSDoc lines). With kill-on-detection wired in server.ts
+//       (`abortForRoleMarker`), a false positive aborts the whole run
+//       — a much more expensive failure than a stray unflagged
+//       `User:` line in the chat scrollback.
+// If a host frontend ever starts parsing chat-style markers as
+// boundaries, narrow the additions to that frontend's specific
+// path rather than the shared regex.
+//
+// Three deliberate refinements vs. a naive `## role` match:
+//
+// 1. CASE-SENSITIVE. The chat host's turn-boundary delimiter is
+//    lowercase (`## user` / `## assistant` / `## system` — see
+//    `buildDaemonTranscript` in apps/web/src/providers/daemon.ts), and
+//    the `## CRITICAL` system-prompt block forbids only the lowercase
+//    forms. Title-Case Markdown headings like `## User Guide`,
+//    `## System Architecture`, `## Assistant settings` are LEGITIMATE
+//    content (LLMs emit these constantly in technical writing) and
+//    must not contaminate. Matching with `/i` would deterministically
+//    abort any run that produced such a heading — exactly the
+//    "false positive aborts the whole run" cost the docblock cites
+//    as the reason to keep the regex narrow.
+//    (See PR #3303 review r3324151877.)
+//
+// 2. POSITIVE LOOKAHEAD `(?=[^a-z])`. Without it, `## userland`,
+//    `## userspace`, `## users guide`, `## systemd`, `## assistance`
+//    all match via prefix in the alternation. The positive lookahead
+//    requires the character after the role keyword to exist AND to NOT
+//    be a lowercase letter:
+//      - `## user\n…`     → match (newline is not lowercase)
+//      - `## assistantR…` → match (R is uppercase; the glued-form
+//                           attack pattern still gets caught)
+//      - `## assistant.`  → match (. is not a letter)
+//      - `## users guide` → no match (s is lowercase letter)
+//      - `## userland`    → no match (l is lowercase letter)
+//    Why POSITIVE `[^a-z]` rather than NEGATIVE `(?![a-z])`: the
+//    negative form is satisfied at end-of-string, which in a streaming
+//    context means "we have just received `## user` but don't know
+//    what comes next yet". A negative lookahead would fire prematurely
+//    if the rest of the role-keyword landed in a later chunk (e.g.
+//    the model emits `## user` then `land` arrives). The positive
+//    form requires an actual non-lowercase character to be present,
+//    so detection waits one more chunk in that edge case — a
+//    one-character latency traded for correctness.
+//
+// 3. `[ \t]` instead of `\s` for inner whitespace. `\s` matches
+//    newlines, which would let oddities like `##\nuser` match across
+//    lines. Markdown role markers are always single-line by
+//    convention; restricting to space/tab tightens the match without
+//    losing any real attack pattern.
+//
+// Alternation order: `assistant` is listed before `assist` so a
+// fully-spelled `## assistant` consumes 9 chars (not 6) and the
+// `(?![a-z])` check is applied at position 9 (after the full word)
+// rather than position 6. Truncated forms (`## assist\n` from a
+// stream cut mid-emission) still match via the `assist` branch.

+// AFTER the role keyword, which by definition can't be present when

+// next byte. If one of these matches, the role keyword IS at the end
+// of the current buffer; we withhold it and revisit on the next

+//       no longer matches the role keyword → withheld bytes are
+//       confirmed safe and emitted alongside the new chunk.
+//   (3) The role keyword is part of a longer word that itself is a
+//       role keyword (only `user` ⊂ `users`, etc. — none extend to
