Behavioral rules that make AI coding agents more reliable — verification, self-correction, and scope discipline.
Debugging guidance and structured report template for thorough bug investigation, evidence gathering, and root cause documentation.
Cold-audit a completed delivery — verify the spec was actually delivered, challenge performative claims, and produce a what-landed report.
Shared implementation guidance for making minimal, correct, maintainable code changes that fit existing systems.
The doctrine for `/roadmap-review` — interactive triage of roadmap-shape drift, walked one item at a time, with paste-ready resolution phrasing for the active sizing lens.
When work would produce 2+ related specs, prefer initiative-first composition over `/design` × N siblings. Carries the canonical "multiple related specs" phrasing that both interactive triage (`/roadmap-review`) and design-time routing (`/design`) quote.

Guidelines for generating self-contained HTML mockups that look professional and are easy to iterate on.
When this skill runs inside a subagent (the usual case via ui-designer or /mock), the subagent's narrative return text is not shown directly to the user — the orchestrator surfaces a parseable file list. The last thing the subagent emits MUST be a <MOCKUP_FILES> block listing every file written:
<MOCKUP_FILES>
.hero/mocks/{slug}/index.html|{Mockup name}|primary
.hero/planning/features/{slug}/spec.md|Spec (Mockups section updated)|spec
</MOCKUP_FILES>
One file per line, pipe-separated path|label|kind. Include every variant when generating multiple options in one run. Skip this block and the user sees no links. See the ui-designer agent definition for full rules.
Selection is now driven by hero spec mock detect (see hero spec mock detect --help). The agent does not decide — the CLI does. This skill is loaded whenever the detect output's renderer field is "html", which fires when no Swift signals are detected, when --renderer=html was explicit, when hero.json mockups.renderer: "html" overrides auto-detect, or as a fallback when Swift signals are present but swiftc is missing.

Keep JS minimal. Common patterns:
Tab switching:
document.querySelectorAll('[data-tab]').forEach(tab => {
tab.addEventListener('click', () => {
document.querySelectorAll('[data-tab]').forEach(t => t.classList.remove('active'));
document.querySelectorAll('[data-panel]').forEach(p => p.style.display = 'none');
tab.classList.add('active');
document.querySelector(`[data-panel="${tab.dataset.tab}"]`).style.display = 'block';
});
});
Modal toggle:
function toggleModal(id) {
const modal = document.getElementById(id);
modal.style.display = modal.style.display === 'flex' ? 'none' : 'flex';
}
Dropdown:
function toggleDropdown(id) {
const dd = document.getElementById(id);
dd.style.display = dd.style.display === 'block' ? 'none' : 'block';
}
document.addEventListener('click', (e) => {
if (!e.target.closest('.dropdown')) {
document.querySelectorAll('.dropdown-menu').forEach(d => d.style.display = 'none');
}
});
Use realistic-looking placeholder data:
When invoked against a spec slug (not free-text), after saving the mockup, link it back from the originating spec so delivery agents can find it.
Locate the spec. Try in order:
.hero/planning/features/{slug}/spec.md.hero/planning/bugs/{slug}/spec.md.hero/specs/{slug}/spec.md (archive fallback)If a ## Mockups section does not exist, append one near the end of the spec body. Place it before ## Validation if that section exists; otherwise at the end of the file.
Add an entry in this format:
- [{Mockup name}](.hero/mocks/{slug}/index.html) — YYYY-MM-DD — one-line description of what the mockup shows
Hero landing page). Use something more specific when the spec has multiple mockups or iteration variants (e.g. Hero landing page — dense variant).On --iterate, match the existing entry by path. If the path is unchanged (the common case — overwriting index.html), update the date in place and rewrite the description only if the iteration meaningfully changed what's depicted. Don't append a duplicate row. If the iteration produces a new file (e.g. dense.html alongside index.html), append a new entry instead.
When /mock is invoked with free-text rather than a spec slug, there is no spec to write back to. Save the mockup under .hero/mocks/_adhoc/{kebab-case-summary}/index.html and skip the write-back step entirely. This keeps the .hero/mocks/ root clean — slug-keyed dirs match real specs; _adhoc/ clearly doesn't.
