Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00094 | $0.01084 |
| Opus 5.5 | $0.00038 | $0.00434 |
| Sonnet 5.5 | $0.00019 | $0.00217 |
| Haiku 4.5 | $0.00009 | $0.00108 |
Grade A, and why
design-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design — Audit
Find what's broken in an EXISTING interface and prioritize fixes by impact. The output is a ranked, actionable issue list — not a vibe check. Every issue ties back to the user's goal, so you're fixing what matters, not nitpicking pixels.
When to use
- An existing screen/flow/site needs critique before iterating.
- "Why is conversion/completion low here?"
- Pre-redesign baseline: what to keep, what to fix.
When NOT to use
- Nothing's built yet →
design-ideate/design-get-context. - You want competitor benchmarks →
design-research. - Final conformance check on a prototype you just built →
design-qa(compares to a spec; audit is open-ended).
Inputs
- Target: live URL, screenshot/image, or component path.
./design/context.md(goal, user, success) if it exists — anchors severity.
Workflow
- Capture the UI: for a URL, use a browser-automation tool (snapshot + screenshot) or a web-fetch tool; for an image, use a vision/read tool; for code, read the components.
- Run heuristic passes:
- Hierarchy: is the primary action obvious within ~2 seconds? One clear focal point?
- Clarity: labels, microcopy, empty/error/loading states present and understandable?
- Flow: step count, friction, dead ends, unnecessary choices.
- Accessibility: contrast ratios, focus order, target sizes (≥44px), alt text, keyboard reachability. (Note: full WCAG conformance needs manual assistive-tech testing — flag it.)
- Consistency: spacing rhythm, type scale, component reuse vs one-offs.
- Conversion: distractions competing with the CTA, trust cues, friction before value.
- Score each issue: severity (high/med/low) × effort (S/M/L). Propose a concrete fix per issue.
- Write
./design/audit.md, sorted by severity. Hand fixes todesign-ideate/design-prototype.
Output: ./design/audit.md
target: https://app.example.com/signup goal: ↑ signup completion
| # | area | issue | sev | fix | eff |
|---|------------|------------------------------------|------|----------------------------------|-----|
| 1 | hierarchy | 3 CTAs same weight above the fold | HIGH | one primary, demote 2 to links | S |
| 2 | clarity | no error state on failed submit | HIGH | inline field errors + summary | M |
| 3 | a11y | CTA contrast 3.1:1 (<4.5 req) | HIGH | darken accent to #1A6FؚE | S |
| 4 | flow | asks company size before email | MED | move optional fields after signup| M |
| 5 | a11y | keyboard focus not visible | MED | add focus ring | S |
notes: full screen-reader pass still required (manual AT).
verdict: 3 HIGH issues likely suppressing completion; fix 1-3 first.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

design-audit is a skill published in the GitHub repository DKeken/codex-skills-alternative (15 stars, last pushed 4mo ago), licensed MIT. It adds 94 tokens to every session and 1,084 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
