Audit Ux And Save Files

Audit UX and Save Files

Disciplined usability evaluation of a running app, from the perspective of the people who actually use it — not a frontend pass. The deliverable is a durable on-disk artifact of usability problems and a prioritized list of the major changes they imply.

Dispatch parallel audit subagents that each embody one persona plus a UX expert's eye, drive the run-agent-browser skill through that persona's core journeys, capture screenshots at the moments friction appears, and write one markdown finding per real usability problem into a dated, persona-scoped, journey-scoped tree under ux-findings/. When the audit returns, cluster findings into UX themes, then synthesize a prioritized recommendations report. This skill reports; it does not fix.

This is not "make it look nicer." The questions are: Can this persona accomplish their goal? Where do they hesitate, misread, backtrack, or give up? What is confusing, redundant, or unnecessary? What one change would help most? Findings are judged by task impact and business consequence, not by pixels.

The skill owns three things: where files live, how usability findings are written (persona · journey · heuristic · severity · behavioral + business impact · recommended major change), and how the audit is synthesized into recommendations. It does NOT own visual/CSS correctness (that is audit-ui-and-save-files) and does NOT implement the recommendations.

When to Use

Trigger on phrases and contexts like:

• "audit the UX", "run a usability audit", "is this actually usable?"
• "where do users get confused / stuck / drop off?", "find the friction"
• "evaluate it as different personas", "walk a first-time user / power user / buyer through it"
• "do a heuristic evaluation of the app", "Nielsen-audit the flows"
• "what's confusing here, what should we simplify or remove?"
• "the feature works — but is it understandable? write up the usability problems for me"
• "screenshot the journeys, find the usability issues, and recommend the big changes"

Do NOT use this skill for:

• Visual / CSS / layout / responsive bugs. "The card overflows at 375px", "contrast is weak", "the grid breaks" → audit-ui-and-save-files. This skill ignores pixels except where they cause a comprehension or task failure.
• Implementing changes. This skill stops at the recommendations report. If the user wants the changes built, that is a separate, explicitly-requested pass (and likely a different skill).
• Single-flow inline check. If the user knows the one flow and just wants a quick read, drive run-agent-browser inline. This skill's overhead pays back at ≥2 personas or ≥3 journeys, or when the problem set is unknown.
• Accessibility-only audits. WCAG/AT conformance needs specialized tooling. (A persona with a disability is in scope as a persona; full a11y conformance is not.)
• Quantitative testing. Analytics, A/B tests, SUS-at-scale measure what happens; this skill is expert + persona-walkthrough and reveals why.

Headline Capabilities (read this section)

Three commitments separate this from a generic "review the UI" run. All three are non-negotiable.

1. The lens is persona + journey + heuristic — never pixels

Every finding answers: which persona, on which journey, hit which usability problem, violating which heuristic, with what behavioral and business consequence, and what major change fixes it. A finding with no persona and no task impact is not a UX finding — it is either a visual nit (wrong skill) or an opinion (cut it). The full finding template, the Nielsen-10 heuristic catalog with common violations, the persona/journey rubrics, and the severity scale all live in references/ux-finding-format.md — plant it verbatim in Phase 2.

2. Findings live in a dated, persona-scoped, journey-scoped tree

ux-findings/[YY-MM-DD]/[persona]/[journey]/NN-short-slug.md

Concrete (a run on 2026-05-28, the first-time user, on the onboarding journey, second issue found):

ux-findings/26-05-28/first-time-user/onboarding/02-value-prop-unclear-on-landing.md

Each segment is mandatory. Full grammar, persona/journey slug rubrics, and screenshot convention in "Output Tree" below and references/ux-finding-format.md.

3. The audit ends in RECOMMENDATIONS, not fixes

After the audit subagents return, cluster findings into UX themes and write ux-findings/[YY-MM-DD]/RECOMMENDATIONS.md — a prioritized list of the major changes (by severity × persona-reach), each with the personas it helps, the journeys it unblocks, and the business rationale. Then stop and report. Do NOT silently implement anything. If — and only if — the user explicitly asks to act, hand off per the routing note in references/synthesis-and-recommendations.md. Read that file before clustering.

The Workflow (Five Phases)

Phase 1 — Frame the personas and journeys (the most important phase)

A UX audit is only as good as its personas. Before dispatching anything, establish:

1. A dev or prod server is reachable. curl -s -o /dev/null -w "%{http_code}" must return 200. Boot the dev server in the background and wait for "Ready" if needed. Never audit a server that is not up.
2. The run-agent-browser skill is available. Check the available-skills list; if absent, surface it and stop — there is no fallback that produces real screenshots.
3. Personas are defined and grounded in the product. Each persona has: a name slug, a one-line identity, their goal ("what they came to do"), their expertise (first-time / returning / power / non-technical), and their context (mobile-on-the-go, evaluating-to-buy, daily-driver). Derive personas from the product's real audience — README, landing copy, pricing tiers, docs, the user. Do NOT invent personas the product was never built for. 2–5 personas is typical. The selection rubric is in references/ux-finding-format.md.
4. Each persona's journeys are listed. A journey is a goal-directed task: onboarding, first-core-task, find-and-evaluate, recover-from-error, upgrade, daily-workflow. Write tasks as goals in the persona's own words, never as click-by-click steps with product jargon — discoverability is half of what you're testing.
5. The audit date is fixed. Compute YY-MM-DD once and pin it for every subagent. Same audit = same date even across midnight.

If personas/journeys aren't obvious, ask the user once. Guessing personas wrong invalidates the whole audit.

Phase 2 — Plant the format spec

Write ux-findings/README.md in the project root before dispatching. Copy it verbatim from references/ux-finding-format.md — every subagent reads this file as the single format authority (finding template, Nielsen-10 catalog, persona/journey rubrics, severity scale, path grammar). Do not paraphrase; subagents are matched against this exact file.

Also create ux-findings/[YY-MM-DD]/screenshots/ as the known flat PNG location (per-persona prefix avoids collisions).

Phase 3 — Dispatch one audit subagent per persona

Partition by [persona]. Each subagent owns one persona, walks that persona's listed journeys, and writes only under ux-findings/[YY-MM-DD]//**. A persona with many journeys can be split, but the default unit is one-subagent-one-persona — because the subagent must stay in character for a coherent walkthrough.

The subagent IS the persona. Use the prompt template in references/persona-subagent-template.md (mission-protocol shape). It instructs the subagent to: adopt the persona's goal and expertise; attempt each journey as that persona would; think aloud (narrate confusion, hesitation, wrong guesses); observe silently — never use insider knowledge to rescue itself past a confusing point (the struggle is the finding); test the error / empty / edge paths, not just the happy path; screenshot the exact moment of friction; and write findings as a UX expert — what the persona did and felt, the heuristic violated, the business impact, the recommended major change. Fill the slots and dispatch. Do not compress the template.

DO NOT fully parallelize browser-driven subagents. run-agent-browser shares a Chrome daemon with a SingletonLock; firing many at once makes them steal each other's sessions and return empty. Stagger (2 at a time, wait for a batch to return) or run sequential single-instance. See references/footguns.md §1.

Phase 4 — Aggregate and find the systemic problems

When subagents return:

1. Inventory:

``bash find ux-findings/ -name "*.md" -not -name "README.md" -not -name "RECOMMENDATIONS.md" | wc -l find ux-findings/ -mindepth 2 -maxdepth 2 -type d | sort # personas × journeys touched `` Track counts by persona, by journey, by severity, and by heuristic.

1. Surface systemic problems — the highest-value patterns. The same confusion hitting multiple personas, or the same heuristic violated across multiple journeys, is a structural problem worth one big change, not many small ones. Lift these to the top.
2. Verify tree shape. Every path must match ux-findings////NN-.md. Move any stray file before continuing.
3. Report a triage summary: counts, severity breakdown, the top systemic problems, the worst per-persona blockers, and a path-to-everything. Do NOT start writing recommendations yet inline — that is Phase 5's structured artifact.

Phase 5 — Synthesize recommendations (report-only)

Follow references/synthesis-and-recommendations.md; the summary:

1. Cluster findings into UX themes. A theme groups findings that share a root cause — a broken journey step, a recurring mental-model mismatch, one confusing concept, or one missing feedback affordance. Merge near-duplicates.
2. Prioritize by severity × reach, not by count. A severity-4 blocker hitting the primary persona outranks ten cosmetic-UX nits. Use the impact/reach/confidence rubric in the reference.
3. Write ux-findings/[YY-MM-DD]/RECOMMENDATIONS.md — for each recommended major change: the problem (one line), the personas + journeys it affects, the supporting finding paths, the recommended change (a direction, not a pixel spec — "collapse the 3-step wizard into one screen with inline preview", "lead with the outcome, not the feature list"), and the expected behavioral/business win. Order by priority.
4. Report and stop. Present the recommendations. Do NOT implement. Only on an explicit user "go" do you hand off (routing in the reference) — and even then, this skill's job was the audit and the recommendations.

[persona] — kebab-case slug for who is using it, grounded in the product's real audience. Rubric (identity · goal · expertise · context) in references/ux-finding-format.md. Examples: first-time-user, returning-user, power-user, evaluator-buyer, admin, mobile-commuter.

[journey] — kebab-case slug for the goal-directed task being attempted. Examples: onboarding, first-core-task, find-and-evaluate, daily-workflow, upgrade, recover-from-error, share-or-invite. A journey is a goal, not a page.

NN-short-slug.md — zero-padded ordinal within [persona]/[journey]/, then a 3–6-word kebab slug naming the usability problem (not the page). Examples: 02-value-prop-unclear-on-landing.md, 05-no-way-to-undo-bulk-delete.md, 03-jargon-blocks-first-task.md.

Each .md follows the template in references/ux-finding-format.md.

Severity Rubric (task-impact framed)

Non-negotiable; every finding gets one label. Severity is about task completion and reach, not how ugly it looks.

• catastrophe (4) — the persona cannot complete a core task or abandons (gives up, leaves, picks a competitor). The journey is blocked.
• major (3) — the task completes but with real cost: confusion, wrong turns, repeated errors, long delay, or a near-abandon. The persona succeeds despite the design.
• minor (2) — a hesitation or moment of doubt that resolves; the persona pauses, re-reads, then proceeds.
• cosmetic-ux (1) — wording/clarity nit with no task impediment (an unclear label that's still guessable).
• (0 = not a UX problem. Do not file. If it's purely visual, it belongs in audit-ui-and-save-files.)

Always annotate reach: how many of the audit's personas hit this. Severity × reach drives Phase 5 prioritization. The full rubric, with the persona-reaction guidance, is carried verbatim in references/ux-finding-format.md.

Footguns

Catalogued with recovery protocols in references/footguns.md. The headline list:

1. Fully parallel browser dispatch causes SingletonLock contention → stagger or run sequential.
2. Filing visual/CSS nits as UX findings → scope bleed into audit-ui-and-save-files. A finding must name a task impact, or it's the wrong skill.
3. Inventing personas the product wasn't built for → personas must be grounded in the real audience; a fabricated persona produces fabricated problems.
4. "I'd prefer X" instead of "the user is blocked by X" → taste is not a usability finding. File behavior and consequence, not preference.
5. Persona drift — the subagent stops role-playing and reverts to an omniscient developer who "knows where the button is." The struggle is the data; insider rescue destroys it.
6. Happy-path-only walks → error, empty, and edge states are where usability dies. The DoD requires testing at least one non-happy path per journey.
7. Findings with no screenshot → an unscreenshotted friction claim is unverifiable; the format spec rejects it.
8. Recommending pixel fixes → Phase 5 recommends directions and major changes, not "move it 8px". Pixel work is the other skill.
9. Recommendations that are a restatement of findings → synthesize across findings into fewer, bigger moves; don't just relist.
10. Implementing instead of reporting → the skill stops at RECOMMENDATIONS.md unless the user explicitly says go.
11. Date computed per-subagent → findings split across two date dirs; pin the date at Phase 1.
